Introduction:
This study was designed as a clinical trial to evaluate and compare the regenerative potential of platelet-rich fibrin (PRF), platelet-rich plasma (PRP), and blood clot in immature necrotic permanent teeth with or without associated apical periodontitis.
Methods:
Access preparation was done under rubber dam isolation. Copious irrigation was done with 2.5% NaOCl and triple antibiotic paste was placed as an intracanal medicament. After 4 weeks, the cases were divided into four groups with five patients in each group. The study design had three test arms and one control arm. Group I in which mineral trioxide aggregate apexification was carried out and it was kept as control group to evaluate the regenerative potential of blood clot and platelet concentrates, Group II in which blood clot was used as scaffold in the canal, Group III in PRF was used as scaffold, and Group IV in which PRP carried on collagen was used as a scaffold.
Results:
The clinical and radiographic evaluation after 6 and 18 months was done by two independent observers who were blinded from the groups. The scoring was done as: None score was denoted by, Fair by 1, Good by 2, and Excellent by 3. The data were then analyzed statistically by Fisher's exact test using Statistics and Data 11.1(PRP Using harvest Smart PReP2) which showed statistically significant values in Group III as compared to other Groups.
Conclusion:
PRF has huge potential to accelerate the growth characteristics in immature necrotic permanent teeth as compared to PRP and blood clot.

REVIEW ARTICLE
Prevention and treatment of white spot lesions in orthodontic patients
Maryam Khoroushi, Marzie Kachuie
January-March 2017, 8(1):11-19
DOI

PMID
:28566845
Decalcification of enamel, appearing as white spot lesions (WSLs), around fixed orthodontic appliances is a major challenge during and after fixed orthodontic treatment by considering the fact that the goal of orthodontic treatment is to enhance facial and dental esthetic appearance. Banded or bonded teeth exhibit a significantly higher rate of WSLs compared to the controls with no braces as fixed appliances and the bonding materials promote retention of biofilms. These lesions are managed in the first step by establishing good oral hygiene habits and prophylaxis with topical fluorides, including high-fluoride toothpastes, fluoride mouthwashes, gels, varnishes, fluoride-containing bonding materials, and elastic ligatures. Recently, other materials and methods have been recommended, including the application of casein phosphopeptides-amorphous calcium phosphate, antiseptics, probiotics, polyols, sealants, laser, tooth bleaching agents, resin infiltration, and microabrasion. This article reviews the currently used methods to manage enamel demineralization during and after orthodontic treatment and the risk factors and preventive measures based on the latest evidence.

Mucormycosis in a diabetic patient: A case report with an insight into its pathophysiology
Syeda Neelam Afroze, Rajani Korlepara, Guttikonda Venkateswara Rao, Jayakiran Madala
October-December 2017, 8(4):662-666
DOI
:10.4103/ccd.ccd_558_17
PMID
:29326525
Mucormycosis is one of the most rapidly progressing and fulminant forms of fungal infection which usually begins in the nose and paranasal sinuses following inhalation of fungal spores. It is caused by organisms of the subphylum Mucormycotina, including genera as Absidia, Mucor, Rhizomucor, and Rhizopus. The incidence of mucormycosis is approximately 1.7 cases per 1,000,000 inhabitants per year. Mucormycosis affecting the maxilla is rare because of rich blood vessel supply of maxillofacial areas although more virulent fungi such as Mucor can overcome this difficulty. The common form of this infection is seen in the rhinomaxillary region and in patients with immunocompromised state such as diabetes. Hence, early diagnosis of this potentially life-threatening disease and prompt treatment is of prime importance in reducing the mortality rate.

Marcelo Carlos Bortoluzzi, Jefferson Traebert, Renata Lasta, Thaiany Naila Da Rosa, Diogo Lenzi Capella, Andréia Antoniuk Presta
October-December 2012, 3(4):393-397
DOI
:10.4103/0976-237X.107424
PMID
:23633796
Objectives:
The aim of this study was to observe the tooth loss over age in a sample of Brazilian patients and analyze their ability to chew, relating it to how much is the loss of oral function impact over the quality of life (QoL).
Materials and Methods:
This is a single center, observational study and the data were collected through clinical examination followed of questionnaires to obtain sociodemographic information, the ability to chew (through the index of chewing ability [ICA]) and QoL (through Oral Health Impact Profile, OHIP-14).
Results:
The sample was composed by 171 random volunteers with mean age of 47 (SD 15.2). Low number of natural teeth was associated with an increase of age (Spearman's rho correlation coefficient-0.7,
P
< 0.001, 2-tailed) and chew disability (ICA: chew's ability vs. disability) (Mann-Whitney U-Test,
P
< 0.001). Chew disability showed a negative impact over the QoL (overall OHIP; Mann-Whitney U Test
P
< 0.001) and in five of seven OHIP domains (Functional Limitation, Physical Pain, Psychological Discomfort, Physical Disability, Psychological Disability). Age over than 40 years, was also associated with chewing disability (Pearson Chi-Square
P
< 0.001) and poorer QoL (Mann-Whitney U test
P
= 0.01).
Conclusion:
This study observed that the chewing disability produces a significant and negative impact over oral-health related QoL and both, poor QoL and chewing disability are related with the decrease of the number of natural teeth.

Rashi Bahl, Sumeet Sandhu, Kanwardeep Singh, Nilanchal Sahai, Mohita Gupta
July-September 2014, 5(3):307-311
DOI
:10.4103/0976-237X.137921
PMID
:25191064
Objective:
The aim of this retrospective study was to evaluate the involvement of fascial spaces, their bacteriology, sensitivity to antibiotics and management of odontogenic infection in 100 patients of age less than 60 years.
Results:
The mandibular 3
rd
molar was found to be the most commonly offending tooth, followed by the mandibular 2
nd
molar. The submandibular space was the most frequently involved fascial space both in single fascial space infections and multiple fascial space infections. Mixed growth (aerobic and anaerobic) was seen in culture smears of 60 patients, only aerobic bacterial growth was seen in 25 patients and anaerobic bacterial growth was seen in culture smears of 15 patients. Streptococcus viridans was the most frequently isolated bacteria among the aerobes, whereas Bacteroides and Prevotella were the most common bacterial species among anaerobes. Empirical antibiotic therapy in the form of Co amoxiclav and Metronidazole was given. Incision and drainage followed by extraction of the offending tooth/teeth was carried out.
Conclusion:
It was concluded that odontogenic infections were mixed aerobic-anaerobic infections. Anaerobic as well as aerobic cultures were necessary to isolate all pathogens. Successful management of these infections depends on changing the environment through decompression, removal of the etiologic factor and by choosing the proper antibiotic.

Introduction
: Prevention of dental caries is one of the main strategies in contemporary pediatric dental practice. Mouth rinses are widely used as an adjunct to maintain oral hygiene. It is important for these products to be effective and safe for regular use in children.
Objective
: The aim of the study was to investigate the efficacy of a newly introduced xylitol, sodium fluoride and triclosan containing mouth rinse in reducing levels of plaque
Streptococcus mutans
and to compare it with that of a 0.12% chlorhexidine mouth rinse.
Materials and Methods
: Thirty children were randomly divided into two groups of 15 children each. Group I (study group) was given a mouth rinse containing xylitol (5%), sodium fluoride (0.05%) and triclosan (0.03%) and Group II (control group) was given a chlorhexidine (0.12%) mouth rinse. Both mouth rinses were alcohol free. Mouth rinsing was carried out twice daily, half an hour after breakfast and half an hour following dinner, for a period of 21 days under the supervision of the investigator.
Results:
In both groups, there was a significant reduction in the mean S. mutans count at the end of 21 days (P < 0.001). No significant difference was observed between the two mouth rinses.
Conclusion:
The use of a low fluoride-xylitol based mouth rinse appears to be a suitable choice for regular use in children.

DOI
:10.4103/ccd.ccd_828_17
PMID
:29875567
Aim:
This study aims to evaluate the antibacterial efficacy of biosynthesized silver nanoparticles (AgNPs) produced using the fungi against
Enterococcus faecalis
biofilm model on root dentin.
Materials and Methods:
AgNPs were biosynthesized using the fungi
Fusarium semitectum
isolated from healthy leaves of
Withania somnifera.
Minimum inhibitory concentration (MIC) of AgNPs was determined by microbroth dilution method using series of dilutions. MIC dose was standardized to evaluate the antibacterial efficacy. For biofilm model, thirty root dentin blocks prepared using human extracted single-rooted teeth were inoculated with
E. faecalis
in Trypticase soy agar broth for 2 weeks with alternate day replenishment and randomly divided into three groups (
n
= 10 each) and treated as: Group I: Sterile distilled water, Group II: AgNPs, and Group III: 2% chlorhexidine gluconate (CHX) and incubated at 37°C for 24 h. Each dentin block was rinsed in saline, vortex shaken for 60 s, and serial decimal dilutions were prepared and plated on trypticase soy agar plates and incubated for 24 h followed by CFU colony counting and statistically analyzed using one-way ANOVA followed by
post hoc
Tukey honestly significant difference test.
Results:
MIC of AgNPs for
E. faecalis
was determined as 30 mg/ml. No significant difference was seen between AgNPs and 2% CHX when compared to the control group with mean colony counts being 2.4, 2.5, and 6.77 CFU/ml (10
7
), respectively (
P
< 0.0001), against
E. faecalis
biofilm.
Conclusion:
Biosynthesized AgNPs exhibit effective antimicrobial activity against
E. faecalis
biofilm on root dentin. Therefore, it can be employed as antimicrobial agent for root canal disinfection.

in vivo
study
Brinda Godhi, PB Sood, Arun Sharma
October-December 2011, 2(4):296-301
DOI
:10.4103/0976-237X.91792
PMID
:22346156
Background:
Preservation of pulp vitality is of utmost importance to the normal physiological functioning of tooth in situ and physiological process of exfoliation in a tooth affected by disease or trauma. Pulpotomy serves such a purpose using various medicaments applied directly on vital pulp.
Aim:
The aim of this study was to evaluate clinically and radiographically the effects of mineral trioxide aggregate (MTA) and formocresol (FC) as a pulp dressing after coronal pulp amputation (pulpotomy) in primary molars prospectively over a period of 1 year.
Materials and Methods:
Thirty-three healthy children, aged between 5 and 8 years, requiring pulp therapy were selected after clinical and radiographic assessment. A total of 50 maxillary and mandibular primary molars were treated by the conventional pulpotomy technique. The teeth were divided into two equal groups. In Group A, FC was used as the pulp dressing agent, and in Group B, MTA was used before restoration with stainless steel crowns. The research employed was a prospective study. The teeth treated were assessed postoperatively after 1, 3, 6 and 12 months. The observations were tabulated and statistically analyzed.
Results:
Clinically, both the groups showed 100% success at 1, 3, 6 and 12 months. At 3 months, the radiographic success rates of FC and MTA were 92% and 96%, respectively, and at 6 and 12 months, the radiographic success rates of FC and MTA were 88% and 96%, respectively.
Conclusion:
MTA showed a higher success rate than FC and may be a favorable material for pulpotomy in primary molars whose pulps have been compromised by a carious or mechanical pulp exposure

Syed Gufran Ali, Sanjyot Mulay, Aparna Palekar, Deepak Sejpal, Anurag Joshi, Hina Gufran
October-December 2012, 3(4):459-463
DOI
:10.4103/0976-237X.107440
PMID
:23633809
Aim:
This prospective randomized clinical study (1) investigated the prevalence of post-obturation pain after single visit root canal treatment and (2) evaluated the influence of factors affecting the pain experience.
Materials and Methods:
One thousand three hundred and twenty eight (1328) patients were included in this study. Conventional single visit root canal treatment was carried out. The chemicomechanical preparation of root canals was done by a rotary protaper system with a combination of hand instruments. Post-operative pain was recorded by each patient by using visual analogue scale in well-defined categories at three time intervals, 12 h, 24 h, and 48 h. The data were analyzed using Fisher's exact test.
Results:
The prevalence of post-obturation pain (severe) within 48 h after treatment was 4% (
n
= 54) but less as compared to the pain experienced after 12 h (9%) and 24 h (8.6%). The factors that significantly influenced post-obturation pain experience were: Age (Fishers exact test = 46.387,
P
= 0.0), gender (Fishers exact test = 23.730,
P
= 0.0), arch (Fishers exact test = 11.710,
P
= 0.001), and presence of pre-operative pain (Fishers exact test = 67.456,
P
= 0.0).
Conclusion:
The presence of post-operative pain was low (4%). The important prognostic determinants of post-obturation pain were: Old age, female, mandibular teeth, and presence of pre-operative pain. The vital condition of the tooth does not affect the intensity and frequency of post-obturation pain.

Inflammatory myofibroblastic tumor is an uncommon lesion of unknown cause. It encompasses a spectrum of myofibroblastic proliferation along with varying amount of inflammatory infiltrate. A number of terms have been applied to the lesion, namely, inflammatory pseudotumor, fibrous xanthoma, plasma cell granuloma, pseudosarcoma, lymphoid hamartoma, myxoid hamartoma, inflammatory myofibrohistiocytic proliferation, benign myofibroblatoma, and most recently, inflammatory myofibroblastic tumor. The diverse nomenclature is mostly descriptive and reflects the uncertainty regarding true biologic nature of these lesions. Recently, the concept of this lesion being reactive has been challenged based on the clinical demonstration of recurrences and metastasis and cytogenetic evidence of acquired clonal chromosomal abnormalities. We hereby report a case of inflammatory pseudotumor and review its inflammatory versus neoplastic behavior.

Context
and
Objective:
Statin treatment, apart from its hypolipidemic action has proven its antimicrobial activity by improving the survival rate of patients with severe systemic bacterial infections. Periodontitis is an inflammatory disorder of tooth supporting structures caused by a group of specific microorganisms. The objective of the present study was to determine the antimicrobial activity of pure simvastatin drug against the primary periodontal pathogens.
Materials
and
Methods:
Minimum inhibitory concentration (MIC) was determined against
Porphyromonas
gingivalis
and
Actinobacillus
actinomycetemcomitans
using serial dilution method.
Results:
MIC of simvastatin against
P. gingivalis
was 2 μg/ml and
A. actinomycetemcomitans
was found to be <1 μg/ml which requires further dilutions to determine the exact value.
Conclusions:
Data suggests a potent antimicrobial activity of simvastatin against both
A. actinomycetemcomitans
and
P gingivalis
. Hence simvastatin can be prescribed as a dual action drug in patients with both hyperlipidemia and periodontal disease.

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
.

DOI
:10.4103/0976-237X.94538
PMID
:22557889
Purpose:
The most common chronic disease of childhood is early childhood caries which is five times more prevalent than asthma and seven times higher than that of allergic rhinitis. Most children do not receive dental care until they are three years old, yet by the time more than thirty percent of children from lower socioeconomic groups already have caries. To determine the prevalence and severity of early childhood caries among pre-school children, to describe the child characteristics associated with the development of early childhood caries and to find the association of early childhood caries and maternal risk factors.
Materials and Methods:
This descriptive study was carried out among children attending the immunization clinic of Sree Avittam Thirunal Hospital, Medical College, Trivandrum and children attending the randomly selected Anganwadies and Day care centres in Trivandrum, the capital of Kerala, wherein there are migrants from all over the State. A total of 350 children aged 12-36 months and their mothers were studied. The mother was first interviewed by a structured questionnaire; then the child's and mothers clinical examination was carried out covering caries experience and oral hygiene status.
Results:
Among 350 children studied the prevalence of dental caries in this study population was found to be 50.6 %( 177). Statistically significant associations were found between the severity of decay and the child's age(
P
<0.001), female gender(
P
<0.05),low socioeconomic status (
P
<0.05), feeding frequency (
P
<0.05), type of feeding(
P

PMID
:25191074
Objectives:
The aim of the present study was to infer and to record the prevalence of incidental maxillary sinus pathologies in patients presenting with dental problems using the cone-beam computed tomography (CBCT) scans performed for maxillofacial diagnostic purposes.
Materials and Methods:
This retrospective study has evaluated 201 patients (402 maxillary sinuses consecutive CBCT) for various incidental maxillary sinus pathologies by two observers. Pathologic findings were categorized as mucosal thickening (MT), opacification (OPA), polypoidal-mucosal thickening (PT), others (antrolith and discontinuity of the sinus fl oor) and no pathologic findings. Correlations for pathologic findings and the factors of age and gender were calculated.
Results:
The prevalence for total incidental findings is 59.7%. The present study showed MT (35.1%) as most prevalent finding followed by OPA in (16.6%), PT in 7.2% and others in 0.7%. There was no statistically significant difference between gender and between the age groups. There was no statistically significant difference between different indications groups for CBCT scans.
Conclusions:
The incidental maxillary sinus abnormalities are highly prevalent in the asymptomatic dental patients; hence oral radiologists should be aware of these incidental findings and comprehensively evaluate the entire captured CBCT volume, which can help in early diagnosis, treatment and follow-up of the patient.

In recent years, age estimation has become increasingly important in living people for a variety of reasons, including identifying criminal and legal responsibility, and for many other social events such as a birth certificate, marriage, beginning a job, joining the army, and retirement.
Objectives:
The aim of this study was to assess the developmental stages of left seven mandibular teeth for estimation of dental age (DA) in different age groups and to evaluate the possible correlation between DA and chronological age (CA) in South Indian population using Willems method.
Materials
and
Methods:
Digital Orthopantomogram of 332 subjects (166 males, 166 females) who fit the study and the criteria were obtained. Assessment of mandibular teeth (from central incisor to the second molar on left quadrant) development was undertaken and DA was assessed using Willems method.
Results
and
Discussion:
The present study showed a significant correlation between DA and CA in both males (
r
= 0.71 and females (
r
= 0.88). The overall mean difference between the estimated DA and CA for males was 0.69 ± 2.14 years (
P
< 0.001) while for females, it was 0.08 ± 1.34 years (
P
> 0.05). Willems method underestimated the mean age of males by 0.69 years and females by 0.08 years and showed that females mature earlier than males in selected population. The mean difference between DA and CA according to Willems method was 0.39 years and is statistically significant (
P
< 0.05).
Conclusion:
This study showed significant relation between DA and CA. Thus, digital radiographic assessment of mandibular teeth development can be used to generate mean DA using Willems method and also the estimated age range for an individual of unknown CA.

Objective:
To determine the effect the early childhood caries (ECC) has on quality of life (QOL) parameters of both children and their parents.
Materials and Methods:
A cross-sectional study was carried out in the Department of Pedodontics and Preventive Dentistry, Manipal College of Dental Sciences, Manipal, India.
Clinical Setting:
The study consisted of 500 children-parent pairs. The study was performed in Manipal and Bhubaneswar (250 children-parent pairs in each group), fulfilling the inclusion requirements of healthy children aged between 3 and 6 years old and children having ECC. The two groups were equally divided as follows: Group I - 250 child-parent pairs (Bhubaneswar) and Group II - 250 child-parent pairs (Manipal and Udupi).
Interventions:
This was a questionnaire-based study and the parents and their children were provided the questionnaires with various questions on QOL parameters. Questionnaires were validated in the respective local languages.
Results:
The data collected were analyzed using the SPSS (version 10.0) package. For assessing the internal consistency of the questionnaire, Cronbach's alfa test was used. To find the comparison between groups, Chi square test and "t" test were used.
Conclusions:
Oral health has a definite effect on the QOL of children. The most affected parameters by ECC were consumption of food and sleep in children, which significantly influence the parents. The questionnaire had good internal consistency in both Kannada and Oriya versions.

The purpose of this study was to evaluate mandibular morphology in different facial types using various parameters. This study was conducted on lateral cephalograms of a total of 110 subjects, which included 55 males and 55 females between the age of 18-25 years having a mean of 22.3 years for males and 21.5 years for females. The sample was divided into normodivergent, hypodivergent, and hyperdivergent subgroups based on Jarabak's ratio. Symphysis height, depth, ratio (height/depth) and angle, antegonial notch depth, ramal height and width, mandibular depth, upper, lower, and total gonial angle, and mandibular arc angle were analyzed statistically and graphically. It was found that the mandible with the vertical growth pattern was associated with a symphysis with large height, small depth, large ratio, small angle, decreased ramus height and width, smaller mandibular depth, increased gonial angle, and decreased mandibular arc angle in contrast to mandible with a horizontal growth pattern. Sexual dichotomy was found with mean symphysis height and depth in the female sample being smaller than in the male sample, but symphysis ratio was larger in the female sample; males having greater ramus height and width, mandibular depth than females. The mandible seemed to have retained its infantile characteristics with all its processes underdeveloped in hyperdivergent group.

Aims and Objectives
: To compare the marginal sealing ability of ormocer with a hybrid composite using an ormocer based bonding agent and a conventional fifth generation bonding agent.
Materials and Methods
: Fifty four human premolars were randomly distributed into four test groups of 12 teeth each and two control groups of 3 teeth each. Class I occlusal preparation of 1.5 mm depth were made in each tooth. These were restored using the adhesive and restorative material according to the group. The restorations were finished using a standard composite finishing and polishing kit. Thermocycling between 5
o
C and 55
o
C was carried out. Having blocked the root apex and the entire tooth surface except 1 mm around the restoration margin, the teeth were immersed in 2% methylene blue for 48 hours, after which the dye penetration through the margins of each sample was studied under a stereomicroscope.
Results and Discussion
: Group IV (Admira with Admira Bond) showed the minimum marginal leakage with a mean of 0.200 mm. Four samples in this group showed no microleakage at all and a maximum of 0.400 mm was seen in one sample. Group II (Spectrum TPH with Admira Bond) showed the maximum leakage with a mean of 0.433 mm. One sample showed as much as 1.00 mm of microleakage. Admira when used with Admira Bond showed lesser microleakage than Spectrum TPH used with Prime & Bond NT, the difference being statistically insignificant.

Context:
Dental trauma has become an important attribute of dental public health. The primary requisite before actively dealing with such problems is to describe the extent, distribution, and associated variables with the specific condition.
Aims:
The aim of the present study was to assess the prevalence and distribution of traumatic dental injuries (TDI) to anterior teeth among 3 to 13 years old Chidambaram school children.
Settings and Design
: A cross-sectional study was conducted. Data was collected through a survey form and clinical examination.
Materials and Methods:
A total of 3200 school children in the age group of 3-13 years were selected from 10 schools of Chidambaram, Tamilnadu. Information concerning sex, age, cause of trauma, number of injured teeth, type of the teeth, lip competence, terminal plane relationship and the molar relationship were recorded.
Statistical Analysis Used:
The statistical software EPIINFO (Version 6.0) was used for statistical analysis. In the present study,
P≤0.05
was considered as the level of significance.
Results:
The trauma prevalence in the present study was 10.13%. Children with class I type 2 and mesial step molar relationship exhibited more number of dental injuries. Enamel fracture was the most common injury recorded. Only 3.37% of the children had undergone treatment.
Conclusion:
The high level of dental trauma and low percentage of children with trauma seeking treatment stresses the need for increased awareness in Chidambaram population.

Reliability of natural head position in orthodontic diagnosis: A cephalometric study
Naveen Bansal, Jeetinder Singla, Gurmeet Gera, Monika Gupta, Gurpreet Kaur
April-June 2012, 3(2):180-183

Natural head position is a standardized and reproducible position, of the head in an upright posture, the eyes focused on a point in the distance at eye level, which implies that the visual axis is horizontal. While natural head position is a standardized position, natural head posture is a physiologic position of the head, when taking the first step forward from the standing to a moving or walking posture. "Orthoposition" is characteristic for a person and reproducible, but differs among persons. Cephalometrics is constantly undergoing refinements in its techniques and analyses to improve the clinical applications. NHP, a long-proposed modification, yet not fully into practice, can be an "ideal" reference for us to improve our cephalometric interpretation. This study was done to investigate sexual difference in the data obtained, from the study between male and female subjects and to compare the data given in 10-measurement cephalometric analysis based on natural head position, with the data obtained from the present study.

Protein carbonyl: An oxidative stress marker in gingival crevicular fluid in healthy, gingivitis, and chronic periodontitis subjects
Avani R Pradeep, MV Ramchandraprasad, Pavan Bajaj, Nishanth S Rao, Esha Agarwal
January-March 2013, 4(1):27-31
DOI
:10.4103/0976-237X.111589
PMID
:23853448
Background:
A defined role for reactive oxygen species (ROS) in the tissue destruction that characterizes periodontitis has been described. Protein carbonyl (PC) is the most widely used biomarker for oxidative damage to proteins, and reflects cellular damage induced by multiple forms of ROS. The purpose of this study is to determine the presence of PC in gingival crevicular fluid (GCF) in healthy, gingivitis, and chronic periodontitis (CP) subjects and to find an association, if any.
Materials and Methods:
A total number of 75 subjects (38 males and 37 females) were selected based on their clinical parameters into three groups: Group 1 (25 healthy subjects), Group 2 (25 gingivitis subjects), and Group 3 (25 CP subjects). GCF samples were collected to estimate the levels of PC.
Results:
The PC concentration in GCF was highest in subjects with CP as compared to gingivitis and healthy subjects and a significant association was observed between GCF PC levels and all periodontal parameters.
Conclusion:
There was an increase in PC levels in GCF as the disease process progressed from healthy to gingivitis and CP, suggesting a role for increased oxidative stress in CP.
