This study showed that serum uric acid was lower in oral cancer patients compared with healthy volunteers and low serum uric acid was associated with increased risk of oral cancer development.

Aims:This study was conducted to assess the sex determination potential from mesiodistal (MD) and buccolingual (BL) dimensions of permanent maxillary first molar.Subjects and Methods:The study was conducted in the Department of Oral Medicine and Radiology, Al-Badar Rural Dental College and Hospital, Gulbarga, Karnataka, on 600 subjects (300 male and 300 female), aged 17–25 years. The subjects were selected based on the inclusion and exclusion criteria set forth for the study. After obtaining informed consent, the intraoral measurements of MD and BL dimensions on casts of the first maxillary molars were taken using digital vernier caliper with resolution of 0.01 mm.Statistical Analysis Used:The data obtained were subjected to statistical analysis using paired and unpaired t-test to compare MD and BL dimensions between males and females. P ≤0.05 was considered statistically significant.Results:The mean MD width of the first maxillary molar was 10.60 ± 0.6644 mm (right) and 10.60 ± 0.6644 mm (left) in males and 10.40 ± 0.6255 mm (right) and 10.40 ± 0.6255 mm (left) in females. The mean BL width of the first maxillary molar was 11.60 ± 1.2227 mm (right) and 11.60 ± 1.2227 mm (left) in males and 11.20 ± 0.8440 mm (right) and 11.20 ± 0.8440 mm (left) in females. The differences between males and females in MD and BL dimensions measured were statistically significant (P < 0.05). Right and left MD dimensions exhibited sexual dimorphism of 1.92% and right and left BL dimensions exhibited sexual dimorphism of 3.57%.Conclusions:The MD and BL dimensions of the maxillary first molars may be used as an aid in sex discrimination.

There is a lacunae for scientific review of curcumin for PMDs specially on OSMF. Appropriate therapeutic interventions are needed for the initial, intermediate, and advanced stages of the disease. High-quality RCTs should be initiated.

Background: Oral submucosal fibrosis (OSMF) is one of the most prevalent premalignant conditions in India which is easy to diagnose but difficult to manage. At present it is considered as irreversible and incurable. It has also been referred to as an epidemic in India. Aims and Objectives: To correlate the frequency and duration of habits with clinical staging, functional staging and histopathological grading and to correlate the clinical and functional staging with histopathological grading. Materials and Methods: The study included a total of 90 subjects, 80 with OSMF in the experimental group and 10 patients in the control group. Patient personal history was recorded with chewing habits, including frequency and duration of chewing. The site of keeping the quid, time duration and whether he/she swallows it or spits it were also noted. Clinical staging was done on the presence of palpable fibrous bands. Functional staging was accomplished by measuring mouth opening. Incisional biopsy was done for all the patients for histopathological examination. Histopathological grading was according to Pindborg and Sirsat. Results: The experimental group comprised 71 males and 9 females, the majority of which were in the age group of 21-30 years. Correlation of habits with clinical staging, functional staging and histopathological grading were significant (p<0.05). Clinical and functional staging did not correlate with histopathological grading, but the correlation of clinical and functional staging was highly significant (p<0.01). Conclusions: The widespread habit of chewing gutkha is a major risk factor for OSMF, especially in the younger age group. In this study, it was found that with increase in the duration and frequency of the habit the severity of the disease increased.

Aims:• This study was conducted to know sex determination potential from mesiodistal dimensions of permanent canines. • To find out the average size of canines in males and females of south Indian population. • To compare the findings with National and International Studies. Study Design: The subjects were selected based on the inclusion and exclusion criteria set forth for the study. Measurements of mesiodistal widths of the four canines were made on the dental casts of each of the 600 subjects with Digital caliper with 0.01 resolution and subjected to statistical analysis. Statistical methods used were statistical mean, standard deviation, Student's t-test (p< 0.05), step-wise discriminant analysis and cross validated discriminant analysis using SPSS version 11.00.
