Background Remineralizing agents demonstrate potential to reverse early carious lesions. Theobromine containing dentifrices claim to remineralize enamel lesions effectively. The aim of this in-vitro study was to evaluate and compare the remineralization potential of dentifrices containing theobromine, 0.21% sodium fluoride (NaF) with functionalized tricalcium phosphate (f-TCP) and amine fluoride on artificial enamel caries. Materials and methods Sound extracted human premolars were demineralized to produce deep artificial carious lesions. The teeth were sectioned longitudinally and allocated to three treatment groups with nine specimens in each group: Group A (NaF + f-TCP), Group B (amine fluoride), and Group C (theobromine). The specimens were then subjected to pH cycling for seven days. Confocal laser scanning microscopy (CLSM) was utilized to record the patterns of demineralization and remineralization. One-way ANOVA and paired t-test were used to analyze changes in lesion depth. The level of significance was set at p<0.05. Results All three dentifrices effectively remineralized artificial carious lesions (paired t-test, p<0.001). Of the groups, Group A (54.97%) reported the highest percentage change in lesion depth values followed closely by Group B (51.51%) and Group C (31.71%), respectively. Conclusion Within this in-vitro study, theobromine containing dentifrice was effective in remineralizing lesions of enamel. However, theobromine demonstrated less remineralization potential in comparison to dentifrices containing NaF + f-(TCP) and amine fluoride.

Background and Objectives: Diabetes mellitus has increased rapidly throughout the world. The objectives of our study were to assess the knowledge and awareness about oral manifestations of diabetes, among type 2 diabetes mellitus patients, their risk for developing oral diseases due to complications associated with diabetes mellitus, and at same time, to perform an oral examination to detect these oral symptoms, if present any, along with the recording of Decayed Missing Filled Teeth Index (DMFT) and Community Periodontal Index (CPI) index. Methodology: Structured questionnaires consisting of 12 different statements on the knowledge base of oral manifestations of diabetes mellitus were distributed to 447 Type 2 diabetes mellitus patients. Following this oral examination, brushing and dental visit history were noted, and CPI index and DMFT indices were recorded in all the patients. Results: Results showed that the knowledge about oral manifestations of diabetes mellitus was poor with a mean value of 4.92 out of a possible score of 12. Among the study subjects, the average score of men was 4.42 while that of females, was 5.41. These scores, when subjected to statistical analysis, were highly significant. (P value- 0.005) Subjects also showed significantly high DMFT (P value <0.001) and CPI scores (P value- 0.270). Conclusion: Our study concluded that there is a significant lack of knowledge about oral manifestations of diabetes mellitus among patients and hence steps have to be taken to increase their awareness through various outreach programs. All health professionals need to work together for promoting better oral health so that oral complications of diabetes can be brought under control.

Aims and Objectives:The purpose of the study was to analyze and compare the incidence of road traffic accidents (RTA) with head injuries and maxillofacial injuries in two arterial roads, Old Mahabalipuram road (OMR) and East Coast road (ECR), connecting with Chennai city and outlining the need of safety precautions to be followed to reduce the incidence of morbidity.Materials and Methods:This study involved the medical records of about 1835 trauma victims who reported to Chettinad Health city, kelambakkam, between August 2008 and June 2013. The data analyzed were, age of trauma victims, gender, type of trauma, type of vehicle, accident time, accident zone, presence of head injury, maxillofacial injury and history of alcohol consumption.Results:Trauma victims were predominantly male (84.3%), with majority of individuals in the age group of 21-40 yrs (56%). About 42% of the reported accidents occurred in OMR and 18.3% of accidents occurred in ECR. About 51.2% of the reported road traffic accidents occurred in the busy traffic hours, between 7am-10am and 5pm-9pm. About 66.4% of RTAs were due to two wheeler vehicles and 21.6% were due to four wheeler vehicles. The incidence of head injury was 47.5% and about 1417 (77.2%) patients reported with maxillofacial injuries.Conclusion:RTAs are more common in OMR than in ECR, involving mostly male victims and two wheeler vehicles, during the peak traffic hours. Rash driving and over speeding of vehicles are the preventable causative factors. Wearing of Helmets by the two wheeler riders and seat belts by the four wheeler riders are essential to prevent morbidity. We stress the need of separate lane for Ambulance on the roads for faster transport of accident victims to nearby Hospital and trauma care centers.
