A microbiological assessment of polymer and conventional carbide burs in caries removal.

Purpose: The purpose of this study was to compare the caries removal efficiency of polymer burs (Smartburs) and conventional carbide burs microbiologically.

Methods: Twenty-four patients participated, each presenting 2 active carious lesions on the occlusal surfaces of primary molars. Sample-taking and caries-removal were done in the following order: (1) first sample (from the carious dentin); (2) caries removal (with a Smartbur or carbide bur); and (3) second sample (from the caries-free dentin), respectively.

The prevalence and surface distribution of caries among schoolchildren in Ankara, Turkey according to their dental health behaviors.

The aim of this study was to classify children according to their oral hygiene behaviors at the elementary school, and to evaluate the effects of oral health behaviors on caries prevalence, and to calculate the number of carious teeth and the surface distribution of caries in school children during a 2-year follow-up period. Results shows that even in the presence of the acquisition of appropriate oral hygiene behavior during preschool period, dental professionals and educational system should supported oral health motivation in primary school.
