Implant Dimensions Commonly Used for the Posterior Mandibular Region among Patients Visiting a Dental Institution in Chennai: Retrospective Study.

Rehabilitation with dental implants is, without doubt, an ordained technique. The clinical utilization of dental implants has accelerated in recent years, and new applications continue to emerge. This retrospective study aims to report the implant dimensions commonly used for the posterior mandibular region. It was done at Saveetha Dental College and Hospitals. A total of 391 patients with 670 implant sites within the 20-80 age group who had undergone implant placement were included in the study. The case sheets of patients were obtained from patient information archives. The data on each patient were obtained and tabulated. Out of the 391 patients, 52.2% were males and 47.8%% were females; 33.3% belonged to the < 35 age group, 34.5% belonged to the 35-46 age group, and 32.2% belonged to the > 46 age group. The prevalence rate of replacement for mandibular molars was 85.2%; for mandibular premolars, 14.8%. Implant dimensions for posterior mandibles were found to differ based on gender and age group. Males had a greater mean implant width compared to females. Implant dimensions with increased height were used in premolars compared to molars. Implant dimensions with increased width were used in molars compared to premolars. In general, implant width ranged from 3.3 to 5 mm and implant height ranged from 9.5 to 13 mm in the mandibular molar region.

Current state of topical antimicrobial therapy in management of early childhood caries.

The treatment of early childhood caries can have a significant economical burden and treatment relapses are frequent. Effective intervention by means of topical antimicrobial agents can reduce the burden of early childhood caries. The main aim in prevention and treatment should focus on inhibition of the growth of oral bacteria. This is a comprehensive review of the literature on the various antimicrobial agents which are proven to be effective in management of this carious progression. The review identified that there is a significant data to suggest use of antimicrobial agents in management of early childhood caries. Antimicrobial agents aid in better management of patients with early carious lesion. The relapse rates are less, when the treatment is combined with the use of antimicrobial agent.

Hepatitis B Infection Awareness among Dental Graduate Students: A Cross Sectional Study.

Hepatitis B virus transmission in a dental setting more commonly occurs due to inadequate/improper use of safety measures by the dentist. This particular study evaluated the hepatitis B virus infection related awareness among dental graduate students in a University Dental College, India. A validated questionnaire regarding the awareness about hepatitis infection and various infection control measures was distributed among the students of different year of study in undergraduate bachelor dental graduate program. The data extracted were tabulated and analyzed. Final year students showed an increased awareness when compared to third year students. There is need for improving the knowledge among the nonclinical students, mainly on transmission of virus through salivary contact. The overall awareness among the students is only fairly satisfying, which signifies the need for continued infection control education among the students.
