Background and Objectives: The absence, destruction, or loss ofβ-cells of pancreas results in type 1 diabetes (insulin-dependent diabetes mellitus [IDDM]). Presently, diagnosis and periodic monitoring of diabetes is achieved by evaluating blood glucose levels as it is relatively invasive and dreaded by children. In the light of this, present study was planned to compare salivary glucose values with blood glucose values and the biochemical characteristics of saliva in IDDM children were evaluated and obtained results were compared with the salivary parameters of normal children. Materials and Methods: Thirty IDDM children and 30 healthy children were selected for the study. Fasting blood sample and unstimulated salivary sample were collected from all the subjects and were subjected for analysis. Results: A weak positive correlation was noticed between fasting blood glucose and salivary glucose values in IDDM children. But a mean average of salivary glucose was high in IDDM children when compared with healthy children. The biochemical parameters like acid phosphatase, total protein count, and α-amylase were increased, whereas salivary urea did not show significant variation between the groups.Conclusion: With presently used diagnostic armamentarium, estimation of salivary glucose cannot replace the standard method of estimation of glucose in diabetic mellitus children. The established relationship was very weak with many variations.

Aim: To investigate the changes in soft tissue parameters of three age groups of untreated Yemenis females. Materials and Methods: The sample comprised 300 Yemeni females which were randomly selected and divided according to age into three equal groups (Group I: 7.34 ± 0.65 years [prepubertal], Group II: 11.11 ± 1.07 years [pubertal], and Group III: 22.17 ± 3.04 years [postpubertal]). Lateral cephalometric radiographs were taken for each subject, and soft tissue measurements were performed. Comparison between the three groups was done. One cephalogram representing the mean of its group was selected from the three groups; the selected three cephalograms (one from each group) were superimposed for growth changes evaluation. Results: Linear, as well as angular soft tissue measurements were significant for all measurements between the different age groups except Ls-Sn Pog', Li-Sn Pog', GSn Pog' and nasolabial angle, respectively. Conclusion: The identified changes with growth in Yemeni females having Class I skeletal and dental relationship should be considered during planning for orthodontic and/or orthognathic treatments.

Aim: Oral lichen planus (OLP) is a chronic mucocutaneous disease with an immunological etiology. This study was conducted to evaluate the effect of selenium combined with Vitamins A, C & E (Selenium-ACE) in the treatment of erosive-ulcerative OLP as an adjunctive to topical corticosteroids plus antifungal agent. Subjects and Methods: Thirty patients with a confirmed clinical and histopathologic diagnosis of OLP participated in this clinical trial. Patients were randomly allocated into one of three groups and treated as follows: (I) Topical corticosteroids, (II) topical corticosteroids plus antifungal, and (III) SE-ACE combined with topical corticosteroids plus antifungal. The patients were followed for 6 weeks. The pain and severity of the lesions were recorded at the initial and follow-up visits. All recorded data were analyzed using paired t-test and ANOVA test. A P ≤ 0.05 was considered significant. Results: The experimental groups showed a marked reduction in pain sensation and size of lesions, particularly in the final follow-up period, but there was no significant difference between the first two Groups I and II. However, healing of lesions and improvement of pain sensation was effective in Group III since a significant difference was found favoring Group III over both Groups I and II. Conclusion: No significant difference was found in treating erosive-ulcerative lesions of OLP by topical corticosteroids alone or combined with antifungal. However, when using SE-ACE in combination with topical corticosteroids plus antifungal, this approach may be effective in managing ulcerative lesions of OLP; but more research with a larger sample size and a longer evaluation period may be recommended.

Aim: This study was conducted to estimate and compare inorganic salivary calcium, phosphate, magnesium, salivary flow rate, and pH of unstimulated saliva and oral hygiene status of healthy subjects, subjects with periodontitis and dental caries, and to correlate salivary calcium level with number of intact teeth. Materials and Methods: The study population consisted of 48 systemically healthy subjects in the age group of 18-55 years, which was further divided into three groups: healthy, periodontitis, and dental caries. Oral hygiene index-simplified, probing pocket depth, clinical attachment level, the number of intact teeth, and active carious lesions were recorded. Estimation of inorganic salivary calcium, phosphate, and magnesium was performed spectrophotometrically using Vitros 5.1 FS. Statistical analysis was performed using the one-way analysis of variance test at 5% significance level. Results: There was a statistically significant increase in inorganic salivary calcium, phosphate, pH, flow rate, and poor oral hygiene status in periodontitis group compared to dental caries and healthy group. Conclusion: Subjects with increased inorganic salivary calcium, phosphate, pH, flow rate, and poor oral hygiene are at a higher risk of developing periodontitis. Since there is increased remineralization potential, these subjects have more number of intact teeth compared to the dental caries group.

Background: The ever-increasing demand for enhanced esthetic appearance has resulted in significant developments in bleaching products. However, the enamel surface roughness (SR) might be negatively affected by bleaching agents. This in vitro study was undertaken to compare the effects of three nanobiomaterials on the enamel SR subsequent to bleaching. Materials and Methods: The crowns of six extracted intact nonerupted human third molars were sectioned. Five dental blocks measuring 2 mm × 3 mm × 4 mm were prepared from each tooth and placed in colorless translucent acrylic resin. The enamel areas from all the specimens were divided into five groups (n = 6): Group 1 did not undergo any bleaching procedures; Group 2 was bleached with a 40% hydrogen peroxide (HP) gel; Groups 3, 4, and 5 were bleached with a 40% HP gel modified by bioactive glass (BAG), amorphous calcium phosphate, and hydroxyapatite, respectively. The enamel SR was evaluated before and after treatment by atomic force microscopy. The data were analyzed by Kruskal–Wallis and Mann–Whitney tests. Results: SR increased significantly in the HP group. SR decreased significantly in the HP gel modified by BAG group as compared to other groups. Conclusions: Within the limitations of this study, incorporation of each one of the three test biomaterials proved effective in decreasing enamel SR subsequent to in-office bleaching technique.

Statement of Problem: Inaccuracies in the fit of palatal major connectors may be related to distortion of the wax pattern due to prolonged storage time and faulty major connector design. Purpose: This in vitro study was carried out to find out the effect of storage time and major connector design on the accuracy of cobalt-chromium cast removable partial dentures (RPDs). Materials and Methods: A brass metal die with a Kennedy Class III, modification 1, the partially edentulous arch was used as a master die. Thirty-six refractory casts were fabricated from the master die. The refractory casts were divided into three groups (Group I: Anterior-posterior palatal bar, Group II: Palatal strap and Group III: Palatal plate) based on the design of maxillary major connector and subdivided into four groups (sub Group A: 01 h, sub Group B: 03 h, Sub Group C: 06 h, and sub Group D: 24 h) based on the storage time. For each group, 12 frameworks were fabricated. The influence of wax pattern storage time and the accuracy of the fit palatal major connector designs on the master die were compared. Casting defects (nodules/incompleteness) of the frameworks were also evaluated before finishing and polishing. Repeated measures analysis of variance was used to analyze the data. Results: The gap discrepancy was least in sub Group A (01 h) followed by sub Group B (03 h) and C (06 h) and most in sub Group D (24 h). Statistically significant differences (P < 0.05 in all locations L1–L5) in the fit of the framework were related to the design of the major connector. The gap discrepancy was least in Group I (anterior-posterior palatal bar) followed by Group II (palatal strap) and most in Group II (palatal plate). Conclusions: It is recommended that the wax patterns for RPD to be invested immediately on completion of the wax procedure. The selection of a major connector design is crucial for an accurate fit of RPD.

Aims: To assess whether educating the parents, teachers, and intermediate school children of Amritsar city about the emergency management of tooth avulsion was an effective method of increasing success rate of treatment of avulsion. Subjects and Methods: Self-administered questionnaires were prepared for 200 parents, teachers, and for intermediate school children to assess baseline knowledge. Sociodemographic distribution of the targeted group was carried out applying Kuppuswamy scale. Two months later, flip cards and posters were distributed to the selected sample followed by a reinforcement session conducted after 1 month in the form of slide presentations on dental trauma. After 3 months, reassessment performance was distributed to the same participants for reassessing any change in baseline knowledge. Further analysis of knowledge, attitude, and practices were carried out after 6 months. The scores based on Likert scale ranging 0-3 were obtained and put to statistical analysis to analyze efficacy of this program 12 months from baseline data. Results and Conclusion: Wilcoxon signed ranked test was applied to nonparametric data to study the knowledge before and after education was carried out. There was a significant change in the knowledge level of children, teachers, and parents after the campaign and teachers showed more positive change in the practice of emergency management of tooth avulsion, endorsing the fact that comprehensive dental education programs targeting school teachers and children can change the perspective of individuals toward treatment needs for dental trauma involving avulsion.

Background: The presence of an adequate width of keratinized tissue is important to maintain a healthy dentogingival junction. In case of inadequate width of attached gingiva, the gingival augmentation procedure has been performed classically using the patient's own masticatory mucosa and more recently, using an acellular dermal allograft as the donor material. Aims: The aim of the clinical study was to evaluate and compare the effectiveness of free gingival graft (FGG) and acellular dermal matrix (ADM) allograft in the ability to increase the zone of attached gingiva. Materials and Methods: Fifteen patients with 30 sites showing the inadequate width of attached gingiva (≤1 mm) were enrolled for the split-mouth study. The width of keratinized gingiva and other clinical parameters were recorded at baseline and 12^th month postoperatively. Statistical Analysis: The difference in clinical parameters within the group was assessed by Wilcoxon signed rank test. However, Mann–Whitney U-test was used to analyze the differences between test and control groups. Results: The width of attached gingiva increased significantly (P < 0.01) following both the treatments but comparatively lesser gain with ADM allograft (2.13 mm vs. 4.8 mm). ADM site had significantly more shrinkage (76.6%) than FGG site (49.7%). Though FGG was found to be more effective, clinicians can prefer ADM allograft because of its certain advantages over the FGG. Conclusion: ADM allograft has resulted in sufficient increase in width of attached gingiva although lesser than FGG. Considering the disadvantages of FGG, it can be concluded that ADM allograft can be used as an alternative to FGG in increasing width of attached gingival in certain clinical situations.

Background: The human first maxillary molar provides clues about evolution and is functionally important. It has four main cusps, and each cusp has an independent growth pattern and different evolutionary background. Though less explored, the analysis based on measurement of each cusp appears to be more meaningful biologically than conventional measurements of the whole crown. Aim: This study aimed to demonstrate the extent of sexual dimorphism in permanent maxillary first molar cusp diameters and their potential utility in sex prediction among Indians using logistic regression analysis (LRA). Materials and Methods: The mesiodistal and buccolingual (BL) crown diameters along with cusp dimensions and cusp indices of right maxillary first molar were measured in an Indian sample (149 males, 151 females; age range of 18–30 years). The possible sex dimorphism in these parameters was evaluated, and LRA was performed to ascertain their usefulness in sex prediction. Results: BL crown dimension and the hypocone (distolingual) cusp showed the highest sexual dimorphism. The combination of metacone and hypocone, i.e., distal cusp diameters among cusp parameters showed the highest accuracy (61.3%). While, on combining all the crown and cusp diameters together the overall accuracy was raised (64.3%). Conclusion: This study supports the ontogeny hypothesis suggesting that early-forming mesial cusps demonstrate less sexual variation as compared to subsequently formed distal cusps in the maxillary molar. Though the sex identification accuracy for cusp diameters of the permanent maxillary first molar in Indians is relatively moderate (≈61%), it can be used as an adjunct for sexing of adult Indians in forensic contexts.

Introduction and Aim: Banana is used widely because of its nutritional values. In past, there are studies that show banana plant parts, and their fruits can be used to treat the human diseases. Banana peel is a part of banana fruit that also has the antibacterial activity against microorganisms but has not been studied extensively. Since, there are no studies that relate the antibacterial activity of banana peel against periodontal pathogens. Hence, the aim of this study is to determine the antimicrobial activity of banana peel extract on Porphyromonas gingivalis (P. gingivalis) and Aggregatibacter actinomycetemcomitans (A. actinomycetemcomitans). Material and Methods: Standard strains of P. gingivalis and A. actinomycetemcomitans were used in this study which was obtained from the in-house bacterial bank of Department of Molecular Biology and Immunology at Maratha Mandal's Nathajirao G. Halgekar Institute of Dental Sciences and Research Centre. The banana peel extract was prepared, and the antibacterial activity was assessed using well agar diffusion method and minimum inhibitory concentration was assessed using serial broth dilution method. Results: In the current study, both the tested microorganisms showed antibacterial activity. In well diffusion method, P. gingivalis and A. actinomycetemcomitans showed 15 mm and 12 mm inhibition zone against an alcoholic extract of banana peel, respectively. In serial broth dilution method P. gingivalis and A. actinomycetemcomitans were sensitive until 31.25 μg/ml dilutions. Conclusion: From results of the study, it is suggested that an alcoholic extract of banana peel has antimicrobial activity against P. gingivalis and A. actinomycetemcomitans.

Aim: To compare the efficacy of powered toothbrushes in improving gingival health and reducing salivary red complex counts as compared to manual toothbrushes, among autistic individuals. Materials and Methods: Forty autistics was selected. Test group received powered toothbrushes, and control group received manual toothbrushes. Plaque index and gingival index were recorded. Unstimulated saliva was collected for analysis of red complex organisms using polymerase chain reaction. Results: A statistically significant reduction in the plaque scores was seen over a period of 12 weeks in both the groups (P < 0.001 for tests and P = 0.002 for controls). This reduction was statistically more significant in the test group (P = 0.024). A statistically significant reduction in the gingival scores was seen over a period of 12 weeks in both the groups (P < 0.001 for tests and P = 0.001 for controls). This reduction was statistically more significant in the test group (P = 0.042). No statistically significant reduction in the detection rate of red complex organisms were seen at 4 weeks in both the groups. Conclusion: Powered toothbrushes result in a significant overall improvement in gingival health when constant reinforcement of oral hygiene instructions is given.

Background: The intake of green tea has been increased recently due to its medicinal values. The antibacterial and antioxidant properties of green tea were found to be beneficial in the treatment of gingival and periodontal diseases. The aim of this comparative study was to compare the efficacy of the mouthwash containing green tea and chlorhexidine in the management of dental plaque-induced gingivitis. Materials and Methods: Thirty patients who participated in the study were divided randomly into two groups, each group of 15 patients was prescribed with either chlorhexidine or green tea mouthwash. Turesky modification of Quigley-Hein plaque index, Löe and Silness gingival index, Ainamo and Bay bleeding index, tooth stain, and tongue stain (TS) were recorded at baseline, 15 days, and 1 month. The subjects were asked to report any discomfort or alteration in taste. Results: There was a significant decrease in plaque index, gingival index, and bleeding index in both the groups. However, green tea mouthwash resulted in a statistically significant decrease in bleeding index compared to chlorhexidine group. There was no significant difference in tooth stain and TS in both the groups. Conclusion: The green tea-containing mouthwash is equally effective in reducing the gingival inflammation and plaque to chlorhexidine.

Context: Platelet-rich-plasma (PRP) and Platelet-rich-fibrin (PRF) are extensively used autologous platelet concentrates in periodontal regeneration, and PRF has a better efficacy as compared to PRP. The rationale for this difference has often been attributed to the difference in the structure of the fibrin matrix. However, the effect of concentration of platelets on the regenerative potential of these concentrates is obscure. Aims: The study was conducted to evaluate and compare, clinically and radiographically, the efficacy of PRF and PRP in the treatment of periodontal endosseous defects and to assess the effect of platelet concentration on periodontal regeneration. Materials and Methods: Twenty intrabony defects were selected and divided into two groups randomly by the coin toss method. Group I received PRP and Group II subjects were treated with PRF. The platelet counts in PRP and PRF were analyzed. Clinical and radiological parameters were assessed at baseline and 3, 6, and 9 months postoperatively. Statistical Analysis: Kruskal–Wallis Chi-square test, Wilcoxon signed rank test, t-test, and Spearman's rank correlation were used for statistical analysis of data. Results: There was statistically significant improvement in all the parameters in the two groups except in relation to gingival recession. There was a statistically significant difference between the platelet count in Group I and Group II (P = 0.002). Conclusion: PRP and PRF appear to have nearly comparable effects in terms of periodontal regeneration. The concentration of platelets appears to play a paradoxical role in regeneration. The regenerative potential of platelets appears to be optimal within a limited range.

Aims: To compare and evaluate the effectiveness of Canal Brushing technique, sonic activation, and master apical file (MAF) for the removal of triple antibiotic paste (TAP) from root canal using scanning electron microscopy (SEM). Materials and Methods: Twenty-two single rooted teeth were instrumented with ProTaper up to the size number F2 and dressed with TAP. TAP was removed with Canal Brush technique (Group I, n: 6), sonic (EndoActivator) (Group II, n: 6), and MAF (Group III, n: 6). Four teeth served as positive (n: 2) and negative (n: 2) controls. The roots were split in the buccolingual direction and prepared for SEM examination (×1000) at coronal, middle, and apical third. Three examiners evaluated the wall cleanliness. Statistical Analysis: Statistical analysis was performed by Kruskal–Wallis test and Wilcoxon rank sum test. Results: Difference in cleanliness between three groups is statistically significant in cervical region only. Pairwise comparison in cervical region Canal Brush and sonic activation showed more removal of TAP than MAF. Conclusions: Canal Brush and sonic activation system showed better result than MAF in the cervical and middle third of canal. In the apical third, none of the techniques showed a better result. None of the techniques showed complete removal of TAP from the canal.

Purpose: To review the clinical pattern and treatment modalities meted out to patients of odontogenic myxoma (OM) in Indian population in last 30 years and also to report 3 cases of OM. Method: A retrospective review of radiograph and histopathology of three cases of odontogenic myxoma treated between 2005 and 2011 was done. Immunohistochemical analysis was performed to examine the pattern of vimentin and NSE. Also a computerized literature search using Medline and Google scholar was conducted for published articles on OM in Indian population in last 30 years. Result: A total of 32 OM cases reviewed from 25 articles retrieved. Out of them 24 myxomas were present in maxilla, only 8 were in mandible and a single case was present in supraglottic region (larynx). Surgical procedure carried out was excision and curettage in 16 patients and resection with safe margin followed by reconstruction 13 patients. All the three reported cases were successfully treated by tumor enucleation and peripheral ostectomy with no recurrence after 3 to 7 years. Conclusion: Odontogenic myxoma is a rare odontogenic tumor with inconclusive clinical and radiographic features, hence histopathological examination is mandatory to confirm its diagnosis. Although the immunohistochemical analysis may help in diagnosis but plays no role in guiding treatment planning or predicting the rate of recurrence. Currently we lack data on number of reported OM cases in Indian population as author feels more patients must have been treated then reported.

Introduction: Malignancies constitute a wide variety of disorders having high mortality and morbidity rates. Current protocols for management include surgical intervention, chemotherapy, and radiation which possess numerous adverse effects. Many phytochemicals are available with anticancer properties similar to anticancer drugs. Major benefit of these compounds is apparent lack of toxicity to normal tissues. Graviola (botanical name: Annona Muricata) contain bioactive compound “annonaceous acetogenins” known for anticancer activity on cancer cell lines. Aims: To determine cytotoxicity of Graviola and percentage cell inhibition at G2M phase of cell cycle. Settings and Design: The cytotoxicity of aqueous extract of Graviola leaves on squamous cell carcinoma (SCC-25) cell lines at various concentrations evaluated using 3-(4,5-dimethylthiazol-2-Yl)-2,5-diphenyltetrazolium bromide (MTT) assay. The percentage of SCC-25 cell inhibition at G2M phase of cell cycle determined using flow cytometry. Methods: Graviola Leaves, American Type Culture Collection SCC-25 cell lines were procured from Skanda Laboratories, Bengaluru. The cytotoxicity of aqueous extract of Graviola on SCC-25 cells at various concentrations evaluated using MTT assay. The percentage of SCC-25 cell inhibition at G2M phase of cell cycle determined using flow cytometry. Statistical Analysis: Statistical analysis was done using one-way ANOVA. Results: MTT assay showed statistically significant (P < 0.001) dose-dependent inhibition of SCC-25 cell lines by Graviola with IC50 value of 12.42 μg/ml. Flow cytometry revealed that Graviola at 25 and 50 g/ml arrested 53.39% and 52.09% cells in G2M phase of cell cycle respectively, which was statistically significant. Conclusion: Graviola showed significant cytotoxic activity and percentage of cell inhibition at G2M phase cell cycle against SCC-25 cell lines.

Background: In the present scenario, we are made available with chemomechanical caries removal system containing a natural proteolytic enzyme for the ease in the excavation of infected dentine. The additive action for these agents is providing antimicrobial and anti-inflammatory properties. Aim: This study was undertaken for assessing the action of Carie Care™ and Papacarie Duo™ on Aggregatibacter actinomycetemcomitans. Materials and Methods: The samples were collected for cultivation of the periodontal pathogen from the clinical periodontal pockets using sterile paper points. The samples cultured under suitable conditions were analyzed with quantitative polymerase chain reaction targeting 16s r-DNA. The samples were divided into three groups namely, Group A: Control, Group B: With Papacarie Duo, Group C: With Carie Care. The pathogen inoculums plugs were inserted in the petri dishes containing chemically defined medium and the experimental gels at different concentrations and were incubated under optimal conditions. The inhibition of growth of the pathogen was studied visually. Results: There was visual inhibition of growth for Group B and C and also exhibited a dose-dependent effect also. Conclusion: Based on the results of the present study, Carie Care™ gel demonstrated better antimicrobial action against A. actinomycetemcomitans which is a major periodontal disease causing pathogen.

Background and Objective: The incidence of maxillofacial trauma is increasing at a very fast pace in developing countries like India and poses a major health burden. Hence, the epidemiological data of maxillofacial trauma during a 6 year period, was analyzed to study the characteristics, factors predisposing, and aid in advocating strict guidelines to prevent the same. Materials and Methods: Data related to 638 cases with maxillofacial trauma, from January 2008 to December 2014 were reviewed retrospectively and the data regarding gender, age, etiology, anatomic location of fracture, alcohol consumption, associated head and other injuries, modality of treatment rendered and associated complications were analyzed with descriptive statistics. Results: A total of 638 patients presenting with 869 maxillofacial fractures were analyzed. Most of them [344 (53.9%)] were young adults aged 18-40, whereas, 123 (19.2%) were 11 to 17 years, and 97(15.2%) adults. Men (79.4%) were more affected than women. Road traffic accidents remain the main etiology causing fractures in 470 (73.6%), whereas 397 (62.2%) had history of consumption of alcohol. Those with alcohol intoxication had multiple injuries. Mandible was more frequently involved with 360 (41.4%) fractures, and condyle being the most common site. A total of 374 (58.6%) underwent open reduction with internal fixation under general anesthesia. Prevalence of other injuries was noted in 207 (32.4%) and complications of fracture treatment in 41(6.4%) cases. Conclusion: Road traffic accidents under alcohol influence were most commonly associated with comminuted facial fractures with head injuries, frequently leading to death. Mandible was the most commonly fractured facial bone followed by zygoma

Successful endodontic treatment depends upon the clinician's knowledge and ability to manage aberrant anatomy. The mandibular canine normally comprises one canal and one root but 15% may have two canals with one or two foramina and even less frequent may have two roots. This paper presents a case report of bilateral mandibular canine having two root canals which merge into one canal and one foramina.

Myiasis is a universal term for extreme infection by the parasitic fly larvae that feed on their host living/dead tissue. Gingival myiasis is a rare disease in the humans associated with poor oral hygiene, suppurative oral lesions, alcoholism, and senility, among other conditions. We present a case of gingival myiasis in the maxillary anterior region on the palatal surface in a 21-year-old mentally challenged male with moderate periodontitis and neurologic deficit. The diagnosis was made on the presence of larvae in the lesion. Treatment done was a manual removal of the larvae, one by one, with the help of the clinical forceps, surgical debridement of the oral wound, and subsequent management of the periodontal disease.

There are a number of systemic diseases causing bony lesions throughout the body. Secondary hyperparathyroidism (HPT) which is associated with chronic renal failure is one such disorder resulting in a variety of bony changes. Secondary HPT develops when the parathyroid hormone is continuously produced in response to chronic low levels of serum calcium, a situation usually associated with the chronic renal disease. Here we present a case of secondary HPT causing bony changes in maxilla and mandible.

Clear cell odontogenic carcinoma is a rare, aggressive neoplasm of the jaw with only 74 reported cases. It occurs predominantly in the mandibular anterior region during fifth to seventh decades of life. Clinically it manifests as intra-bony swelling with a variable degree of pain. Microscopically, it reveals nests of cells with clear cytoplasm in connective tissue stroma arranged in different patterns. It is often misdiagnosed due to the rarity of lesion and confusing histopathology. Immunohistochemical staining plays an intricate role to uncertain the native of the clear cell to reach a confirmative diagnosis. The article aims to highlight the clinicopathologic features of clear cell odontogenic carcinoma in a middle-aged man with special emphasis on its differential diagnosis.

Peripheral ameloblastoma (PA) is a rare and unusual entity with histological characteristics similar to those of the common intraosseous ameloblastoma. In this paper, we present a case of PA in a 44-year-old male affecting the right retromolar trigone area along with its immunohistochemical profile using CK19 and Ber-EP4 markers.

Unilateral cleft lip and palate (UCLP) patients have an esthetic and functional compromise of the middle third of the face and nasal structures. To improve the esthetic result of lip repair, the concept of presurgical nasoalveolar molding (PNAM) was brought into conception. PNAM is an easy and passive method of bringing the alveolus and lips together by redirecting the forces of natural growth. This case report documents a 2-year follow-up of PNAM in UCLP.

The furcation area creates situations in which routine periodontal procedures are somewhat limited, and surgical procedures are generally required. The introduction of bioactive agents, such as platelet concentrates, enamel matrix derivatives, bone morphogenic proteins, and matrix macromolecules such as hyaluronic acid has expanded the scope for better outcomes in furcation treatment. Hyaluronic acid is a naturally occurring nonsulfated high molecular weight glycosaminoglycan that forms a critical component of the extracellular matrix and contributes significantly to tissue hydrodynamics, cell migration, and proliferation. Platelet-rich fibrin (PRF) is an immune and platelet concentrate containing all the constituents of a blood sample, which are favorable for healing and immunity. The purpose of the present case report was to assess through surgical re-entry, the regenerative capacity of Gengigel^™ in conjunction with PRF in a patient with grade II furcation defect. It was observed that the combined approach resulted in significant furcation defect fill on re-evaluation at 6 months.

Endodontic treatment options for immature, nonvital teeth conventionally include surgical endodontics, apexification with calcium hydroxide, or single visit mineral trioxide aggregate plug. Regeneration is a new concept which is been introduced in the treatment of traumatized open apex tooth. Regeneration of pulp-dentin complex in an infected necrotic tooth with an open apex is possible if the canal is effectively disinfected. The purpose of this case report is to add a new vista in regenerative, endodontic therapy by using platelet-rich fibrin for revitalization of immature nonvital tooth.

Epithelioid hemangioendothelioma (HE) is an intermediate malignant potential vascular neoplasm with uncertain clinical behavior, wide variations in microscopic findings, and prognosis. According to the World Health Organization (2002) classification, epithelioid HE has been considered under malignant tumors which rarely metastasize. The epithelioid variant, the most aggressive one, has similar gender predilection and sporadic occurrence in children. The patients usually present with an asymptomatic oral mass whereas few cases may report with the painful bleeding lesion. We attempt to present a case in an adolescent male with previously never described biological behavior, diverse histopathological features, and immunohistochemistry findings.

The term juvenile ossifying fibroma (JOF) is used in literature in naming two microscopically distinct fibro-osseous lesions of the craniofacial skeleton. One is characterized by small uniform spherical ossicles resembling psammoma bodies (psammomatoid JOF [PsJOF]). The other is distinguished by trabeculae of fibrillary osteoid and woven bone (trabecular JOF). Psammomatoid ossifying fibromas represent a unique subset of fibro-osseous lesions of the craniofacial region. PsJOF has been distinguished because of its location, clinical behavior, and age of occurrence. They have distinctive histomorphologic features and a tendency toward locally aggressive behavior, including invasion and destruction of adjacent anatomic structures. It is generally seen in the younger age group, and the most common site is paranasal sinuses, orbits, and frontoethmoidal complex. We report a case of JPOF involving mandible which is rarely been described in literature. An insight into the radiographic progression of this rare entity along with the clinical feature and surgical management is discussed.

Lymphangiomas are benign hamartomatous tumors of the lymphatic channels which present as developmental malformations arising from sequestration of lymphatic tissue that do not communicate with the rest of the lymphatic channels. Lymphatic vessels are filled with a clear protein-rich fluid containing few lymph cells. It can also occur in association with hemangioma. The onset of lymphangiomas are either at birth (60% to 70%) or up to two years of age (90%) and rare in adults. Lymphangiomas have marked predilection for the head and neck region (50-70%). The most common location in the mouth is the dorsum of tongue, followed by lips, buccal mucosa, soft palate, and floor of the mouth. On tongue, they may present as a localized or a diffused growth which may enlarge to cause macroglossia, impaired speech and difficulty in mastication. Herewith, we present a rare case of lymphangioma of tongue leading to macroglossia in a 8-year-old boy.
