Objectives: The purpose of this case series was to compare the clinical, radiographic, and histopathologic features of 11 cases of ameloblastoma that reported to the Goa Dental College and Hospital over a period of 4 years from January 2008 to December 2012. Study Design: Data with respect to the patients' ages, sex, location of lesions, radiographic features, histopathologic features and surgical treatment and follow-up, was analyzed. Results: The mean age in males was 23.25 ± 6.99 years, while that in females was 43.43 ± 17.13 years. Seven (63.63%) of the 11 subjects were females, and four (36.36%) were males. 10 (90.9%) of the 11 ameloblastomas were located in the mandible. Swelling was noted in all 11 patients. 10 cases showed radiographic findings, while one case was a peripheral soft-tissue variant. Seven (70%) of the 10 tumors were multilocular with a well-demarcated corticated border, and three cases (30%) were unilocular. Two cases showed a soap-bubble appearance. Histologically, five cases were unicystic, four were multicystic, one was desmoplastic and one was a peripheral variant. Follow-up ranged from 12 to 34 months and there were no signs of recurrence in any of the patients. Conclusions: Ameloblastomas more commonly occur in females at an older age, as compared with males. Radiographic features that could help in diagnosing ameloblastomas include its predominant occurrence in the mandible, multilocular radiolucency with well-defined, corticated, scalloped margins, expansion of buccal and lingual cortical plates, root resorption and tooth displacement.

Objective: The objective of this study is to investigate the influence of flap design on visibility and accessibility during removal of impacted third molar and hematoma formation, wound gaping and healing of flap post-operatively. Study Design: The randomized prospective comparative study included 30 patients with impacted mandibular third molars. Two flap designs namely "envelope flap" (Koener's incision) and 'triangular flap' (Ward's incision) were used. After 7 days, sutures were removed and status of wound, periodontal health, and progress of healing was assessed. Patients were followed through 15 days to judge the incidence of post-operative complications in both groups. Results: No statistical differences were noted between the groups in terms of visibility, accessibility, excessive bleeding during surgery, healing of flap, sensitivity of adjacent teeth, and dry socket. A statistically significant difference was observed in post-operative hematoma, wound gaping, and distal pocket in adjacent tooth, which was significant in Ward's triangular incision group in comparison to Koeiner's envelope incision group. Conclusion: The selection of the flap design is dependent on needs of the case and preference of the operating surgeon and does not seem to have a significant influence on the health of tissues. In order to avoid wide area of exposure of bone, the operating surgeon should clinically and radiographically assess the designing of incision and mucoperiosteal flap, the clinical relevance is still debatable.

Objective: To evaluate the upper airway dimensions in adolescents treated for bimaxillary proclination with first premolar extraction. Materials and Methods: A retrospective cephalometric evaluation was carried out on the available pre and post orthodontic treatment records of 150 patients (12-18 years of age) who had bimaxillary proclination and were treated with fixed orthodontic therapy. Cephalometric landmarks for sagittal airway measurements and hyoid bone were identified; linear and angular measurements were obtained. Descriptive statistics using paired t-test was used to assess changes in pre and post treatment values and Pearson's correlation coefficient was calculated to evaluate the reliability of observations. The method error calculations were performed using the Dahlberg formula. Results: It was observed that the mean values of nasopharyngeal dimension and Total Airway Length (TAL) showed no statistically significant difference in pre and post treatment groups. All other airway and hyoid parameters showed statistically significant difference. Pearson's correlation coefficient showed statistically significant correlations in all the airway and hyoid parameters. Conclusions: In the present study, the nasopharyngeal dimension and TAL were not found to be directly affected by the retraction of anterior teeth, This can be attributed to the fact that nasopharyngeal dimension and TAL are not under direct influence of tongue position. The other findings also indicated direct correlation of tongue position to oropharynx and hypopharynx. Consequently, we emphasize clinically relevant anatomic risk factors that should be given prime importance and serious consideration on the decision whether to extract or not in growing patients.

Aim: To comparatively evaluate the therapeutic efficacy of chlorhexidine (CHX) chips (Periocol-CG) and indigenous curcumin (CU) based collagen as adjuncts to scaling and root planning in the nonsurgical management of chronic periodontitis. Materials and Methods: A total of 120 sites from 60 patients presenting with chronic periodontitis (age group 25-55 years) of both sexes, with pocket depth of ≥5 mm with radiographic evidence of bilateral bone loss were earmarked for the study. A split mouth design was employed, and all the clinical parameters-plaque index, gingival index, probing pocket depth (PPD) and clinical attachment levels (CAL) were recorded at baseline, 1 month, 3 months, and 6 months. However, the microbiological parameters, i.e., N-benzoyl-DL-arginine-β-naphthylamide (BANA) test and microbial colony count were recorded at baseline, 3 months and 6 months postoperatively. Results: Significant reduction in plaque and gingival index scores were observed in both groups at the end of the study period, i.e., 6 months. The microbiological parameters (BANA test, microbial colony count), PPD and CAL levels also showed significant improvement in both groups. However, at the end of the study period CHX group showed greater improvement in all of these parameters compared to CU collagen group. Conclusion: Future directions of this study should include targeting the beneficial effects of these local drug delivery systems at varied concentrations so that they could be utilized to achieve the maximum beneficial therapeutic effects in the nonsurgical treatment of periodontal disease.

Lipoma is a benign neoplasm of mature fat cells. Although a common mesenchymal neoplasm of trunk and extremities, its occurrence in the oral and oropharyngeal region is rather rare. Lipoma accounts for 1-5% of all benign oral tumors, occurring in patients above 40 years of age with slight male predilection. Oral lipoma presents as asymptomatic, slowly growing mass rarely exceeding 25 mm in diameter. Documented here is a rare case of a large size lipoma (>3 cm in diameter) occurring as an extraoral swelling in a girl aged 13 years, which was subsequently diagnosed and treated 4 years later. Furthermore discussed are the peculiarities in the clinical presentation, differential diagnosis, and investigations for this case.

Background: Periodontitis is a common inflammatory disease with complex and multi-factorial origin. Tobacco usage has shown its adverse effect on periodontal health. Various components within saliva not only protect the integrity of oral tissues, but also provide clues to local and systemic diseases and conditions. Salivary thiocyanate (SCN) has been shown to be a chemical indicator in smokers and smokeless tobacco users. Noninvasive nature of salivary testing has made it an attractive and effective alternative to blood and urine testing. Limited studies are there comparing and correlating the salivary SCN levels in smokers with chronic periodontitis (CP). However, no studies show correlation of salivary SCN among gutka chewers with CP. Aims and Objectives: The objective of the following study is to estimate, compare, and correlate the SCN levels in periodontally healthy, CP, smokers with CP and gutka chewers with CP subjects. Materials and Methods: Study includes 120 subjects with age 18-55 years, categorized as periodonally healthy (n = 30), CP (n = 30), smokers (n = 30), and gutka chewers (n = 30) with CP. Required clinical parameters such as gingival index, probing depth and clinical attachment loss were recorded and salivary SCN levels were estimated through ultraviolet-spectrophotometer. Results: Mean salivary SCN level were shown to be higher among smokers and gutka chewers with CP as compared to healthy and CP alone. Conclusion: The present study exhibited the significant increase in salivary SCN levels among smokers and gutka chewers when compared to others, concluding that the analysis of salivary SCN levels could be used as an adjunctive means of diagnosis.

Primary malignant melanoma is a rare and aggressive neoplasm that originates from the proliferation of melanocytes. Although, it comprises 1.3% of all cancers, malignant melanoma of the oral cavity accounts for only 0.2-8% of all reported melanomas and occurs approximately 4 times more frequently in the oral mucosa of the upper jaw, usually on the palate or alveolar gingivae. Most of the mucosal melanomas are usually asymptomatic in early stages, and presents as pigmented patch or a mass delaying the diagnosis until symptoms of swelling, ulceration, bleeding, or loosening of teeth are noted. The prognosis is extremely poor, especially in advanced stages. Therefore, any pigmented lesion of undetermined origin should always be biopsied. We herewith report of two cases of oral malignant melanoma in a 60 and 75-year-old female.

Aim: The aim of the study was to determine the clinical and histopathological effect on palatal hyperplasia caused by suction cups by different methods of management used for recovery of abused tissues. Materials and Methods: A total of 35 subjects agreed for biopsy procedure, from 50 patients who gave consent for the study. Out of the 35 subjects, 20 were randomly selected for treatment with discontinuation of denture (Group I) and 15 selected for denture relined with tissue conditioner (COE-comfort) (Group II). Punch biopsy procedure was performed on these patients to study the histopathology of the lesion before the two modalities of treatment was administered on them. Results: Inflammation caused by suction cup decreased considerably by both the treatment modalities, i.e., the use of tissue conditioner as well as discontinuation of denture (tissue rest) for a period of 2 weeks. Conclusion: It was concluded that wearing denture day and night considerably increased the severity of inflammatory papillary hyperplasia of palate. Healing was better with tissue conditioner when compared with tissue rest.

In the absence of syndromes, bilateral dentigerous cysts (DC) located on the jaws are unusual. In English based language literature review, we only found eight reports of nonsyndromic bilateral dentigerous cyst associated with mandibular third molars. Therefore, we report the unusual occurrence of sizable nonsyndromic bilateral DC associated with mandibular impacted third molars in a 42-year-old Caucasian woman. The lesions were assessed by cone beam computed tomography (CBCT) the right lesion showed approximately 23.64 mm and the left one, 16.57 mm diameter, both located intimately next to the mandibular canal. Bilateral surgical enucleation, related teeth excision of both third molars and plate for fixation placement on the right and bigger lesion, under general anesthesia was the final treatment choice. Clinical, radiographic and histopathological features confirmed diagnose of bilateral dentigerous cyst. Now-a-days, the patient is on 18 months radiograph follow-up with favorable osseous formation with no evidence of recurrence of the cysts.

Myoepithelial carcinoma is a rare neoplasm of salivary glands that account for < 1% of all salivary gland tumors. The most common sites of involvement are major salivary glands mainly parotid gland. Intraorally, it can arise from minor salivary glands; palate is the most common site of occurrence. It also occurs in nasopharynx, paranasal sinuses, nasal cavity and larynx in head and neck region. Myoepithelial tumors were first described in 1943. Their malignant variant, myoepithelial carcinoma, was first reported by Stromeyer et al., in 1975, characterized by distinct morphologic heterogeneity and an infiltrative growth pattern into adjacent tissues. Here, we report a rare case of a 55-year-old female with myoepithelial carcinoma of buccal mucosa. It was also rare because of unusual location of tumor. Our patient was treated with wide local resection and remained free of disease for 15 months.

Since the inception of root form implant dentistry by P-I Branemark in the early 1980's, so many technical advances have been put forward by several authors. However, the open tray impression technique is still performed for impressing multiple implant fixtures as it was first described in the original Branemark procedure manual. The most critical aspect for a successful implant-supported restoration is the passive and an accurate fit of superstructures to avoid preload and loading stresses. Splinting impression technique in multiple implants has gained popularity. Auto-polymerizing acrylic resin is among the most routinely practiced splinting material for multiple implant units. However, unfortunately, it exhibits shrinkage, which makes an impression quite inaccurate. This case report presents the solution to minimize the shrinkage of resin by utilizing sectional-splinting technique as advocated in the previous implant literature.

Burkitt's lymphoma (BL) is the fastest growing malignancy of the lymphoreticular system to affect humans and has a potential ability to double in size every day. A case of maxillary sporadic BL (sBL) associated with neuro-orbital involvement in an Indian male is presented. sBL initially presented as maxillary swelling with no obvious dental and periodontal changes. Histological specimen from incisional biopsy revealed a round cell malignant tumor and immunohistochemistry reactions favored nonHodgkin's lymphoma consistent with BL. Four weeks later, patient presented with orbital involvement as diplopia, sixth cranial nerve palsy, and medial rectus palsy. Chemotherapy regimen according to LMB 89 protocol was started. During chemotherapy regimen patient showed bradycardia and Babinski response, suggestive of central nervous system involvement. sBL associated with orbital involvement is extremely rare and only seven cases have been reported. Our case showed unusual presentation; despite the aggressive tumor did not show any common clinical, radiological, and hematological findings. We also discussed the role of oral medicine specialist, importance of early diagnosis, and prompt referral in management of maxillary sBL.

Paracoccidioidomycosis (PCM) is a deep mycosis with primary lung manifestations that may present cutaneous and oral lesions. Oral lesions mimic other infectious diseases or even squamous cell carcinoma, clinically and microscopically. Sometimes, the dentist is the first to detect the disease, because lung lesions are asymptomatic, or even misdiagnosed. An unusual case of PCM with 5 months of evolution presenting pulmonary, oral, and cutaneous lesions that was diagnosed by the dentist based on oral lesions is presented and discussed.

Aim: The aim of the following study is to evaluate the cleaning capacity of a hybrid instrumentation technique using Reamer with Alternating Cutting Edges (RaCe) system files in the apical third of mesial roots of mandibular molars. Materials and Methods: Twenty teeth were selected and separated into two groups (n = 20) according to instrumentation technique as follows: BioRaCe - chemomechanical preparation with K-type files #10 and #15; and files BioRaCe BR0, BR1, BR2, BR3, and BR4; HybTec - hybrid instrumentation technique with K-type files #10 and #15 in the working length, #20 at 2 mm, #25 at 3 mm, cervical preparation with Largo burs #1 and #2; apical preparation with K-type files #15, #20, and #25 and RaCe files #25.04 and #30.04. The root canals were irrigated with 1 ml of 2.5% sodium hypochlorite at each change of instrument. The specimens were histologically processed and photographed under light optical microscope. The images were inserted onto an integration grid to count the amount of debris present in the root canal. Results: BioRaCe presented the highest percentage of debris in the apical third, however, with no statistically significant difference for HybTec (P > 0.05). Conclusions: The hybrid technique presented similar cleaning capacity as the technique recommended by the manufacturer.

Aims: The aim of this study is to evaluate the treatment outcome of immediately loaded Implants in the interforaminal region of anterior mandible. Materials and Methods: A total of 15 completely edentulous patients aged between 50 and 70 years were selected satisfying certain inclusion and exclusion criteria. Two implants were placed in 33 and 43 region (B and D location) and the implants were loaded immediately by mandibular overdenture retained with O-ring attachments. The implants were evaluated for various clinical parameters at 6 months, 1 year, 1.5 years, and 2 years intervals after initial placement. Results: There was increased marginal bone loss around implants during the 1 ^st year after that the bone loss was insignificant. Clinical stability of immediately loaded implants was lower initially for 6 months, but improved by the end of 1 ^st year. Survival rate for immediately loaded implants was 96.6% at the end of the period of study. Conclusion: Immediate loading of interforaminal mandibular implants demonstrated a highly acceptable clinical success at the end of 2 years. However, initially the marginal bone level and clinical stability were significantly lower which showed improvement with time.

Success in root canal treatment is achieved after thorough cleaning and shaping followed by complete obturation of the canal system. Therefore, endodontic therapy requires specific and complete knowledge of the internal and external dental anatomy, and its variations in presentation. The internal anatomy of the maxillary central incisor is well-known and usually presents one root canal system. This case report describes an endodontic treatment of traumatized both maxillary central incisors with two canal systems. Knowledge of dental anatomy is fundamental for proper endodontic practice. When root canal treatment is performed, the clinician should be aware that both external and internal anatomy may be abnormal.

Objectives: The objective of the following study is to evaluate the usefulness of ultrasonography (USG) in comparison with conventional radiography and computed tomography (CT) scan in the diagnosis of zygomatic arch and mandibular fractures. Materials and Methods: A total of 40 patients with suspected fracture of the zygomatic arch and/or mandibular fractures were included in the study. Two groups (one for zygomatic arch fractures and the other for mandibular fractures) of 20 patients each were designed for the study. Ultrasonographic examinations were performed using small linear probe (LA435, Siemens Acuson Antares) with 10 MHz frequency. Data from CT and conventional radiography were compared with that of USG. Results: Sensitivity and specificity of USG in assessing zygomatic arch fractures were 100% and 100%, respectively; and that of mandibular fractures were 94.74% and 100%, respectively. Overall sensitivity, specificity, positive predictive value, and negative predictive value of USG against CT in diagnosing zygomatic arch and mandibular fractures were found out to be 97.4%, 100%, 100%, and 66.7%, respectively. Conclusion: USG is a very reliable tool in detection of fractures involving zygomatic arch and mandible. It can be used for screening of suspected fractures of zygomatic arch and mandible to avoid unnecessary radiation exposure from conventional radiography and CT scans.

Periapical lesion is a general term used to describe the periapical inflammatory process that occurs in response to the invasion of micro-organisms in the root canal system as well as inflamed vital pulp. This phenomenon necessitates endodontic intervention and if the necrosis has occurred prior to tooth maturation, wide patency of the apical foramen requires some treatment modalities such as apexification or apical plug. Orthodontic treatment, on the other hand, is cautiously done for previously traumatized teeth due to increased risk for necrosis of the compromised tooth. This article tends to review the successful treatment process with calcium-enriched mixture (CEM) cement apical plug for an immature previously traumatized incisor tooth with an extensive periapical lesion, which was under orthodontic treatment as well.

Medication-related gingival enlargement is a common reactionary phenomenon that occurs with the use of several types of therapeutic agents, including antiepileptic drugs (AEDs). This disorder has been documented since 1939, shortly after the introduction of phenytoin. In the present case, a concise review of literature concerning the etiopathogenesis and management of AEDs (phenobarbitone and phenytoin) induced gingival enlargement has been described. It is vital that not only the periodontist, but also dental surgeons and medical practitioners should become aware of the potential etiologic agents, characteristic features, and the differential diagnosis of drug induced gingival enlargement in order to be able to prevent, diagnose and successfully manage the condition.

Gingival fibromatosis is characterized by gingival tissue overgrowth of a firm and fibrotic nature. The growth is slow and progressive and is drug-induced, idiopathic, or hereditary in etiology. It occurs isolated or frequently as a component of various syndromes. Our patient presented with the complaint of gingival enlargement associated with progressive deafness, characteristic of Jones syndrome. This case report is important and unique since it is the first known one to have a Jones syndrome-like presentation without a family history. A male patient aged 14 years reported with the chief complaint of swelling of gums and progressive hearing loss in both ears for the past one year. There was no family history or history of drug intake. Enlargement was generalized, fibrotic and bulbous, involving the free and attached gingiva, extending up to the middle 1/3 ^rd of the crown. Investigations such as pure tone audiogram, impedance audiometry, and Tone decay test concluded that there was severe right and moderate left sensorineural hearing loss. The case was diagnosed to be idiopathic, generalized gingival fibromatosis with progressive hearing loss. The gingival overgrowth was managed by gingivectomy and periodic review. The patient was advised to use high occlusion computer generated hearing aids for his deafness as it was not treatable by medicines or surgery. This unique case report once again emphasizes the heterogeneity of gingival fibromatosis, which can present in an atypical manner.
