Detecting dental calculus is clinically challenging in dentistry. This study used typodonts with extracted premolar and molar teeth and simulated gingival tissue to compare the performance of differential reflectometry and periodontal probing. A total of 30 extracted teeth were set in an anatomical configuration in stone to create three typodonts. Clear polyvinyl siloxane impression material wa...

Periodontally affected root surfaces are hyper mineralized, and contaminated with cytotoxic and other biologically active substances especially endotoxins which play a pivotal role in preventing new connective tissue attachment to the exposed root surface. Following root planing the instrumented root surface is invariably covered by smear layer containing remnants of dental calculus, contaminat...

background and aims. previous researches, conducted mostly on extracted teeth, have shown that efficacy of calculus removal decreases with increasing pocket depth, but there is still a lack of clinical studies concerning the correlation be-tween residual calculus and varying pocket depths. the objective of the present clinical study was to assess the efficiency of mechanical tooth depuration by...

Smoking is a major, preventable risk factor for periodontitis. This pilot study in Nigeria evaluated the effect of dental oral prophylaxis on oral hygiene and periodontal indices among 13 systemically healthy smokers and 8 non-smokers. All participants received full-mouth scaling and root planing, tooth polishing, demonstration of correct brushing technique and a new toothbrush and toothpaste. ...

Abstract Dental calculus and other preserved microbiome substrates are an attractive target for dietary reconstruction in past populations through a variety of physical, chemical, molecular means. Recently, studies have attempted to reconstruct diet from archaeological dental using archaeogenetic techniques. While may provide relatively stable environment DNA preservation, the detection plants ...
