A comparative evaluation of the effect of alcoholic and non alcoholic beverages on tooth enamel surface pretreated with β-tricalcium phosphate, bioactive glass and amine fluoride: an study.

Background And Aims: The aim of this study is to quantitatively evaluate the effect of different alcoholic and non alcoholic beverages on the tooth enamel surface topography pretreated with various remineralizing agents using Atomic Force Microscopy.

Methods: 120 tooth specimens were prepared from 60 freshly extracted intact human premolars by sectioning from mesial to distal surfaces using low speed diamond discs and were randomly assigned to study groups and control group. Specimens of Group I, Group II and Group III were pre-treated with β-Tri calcium phosphate, bioactive glass and amine fluoride respectively for 4 minutes for 28 days, followed by storage in artificial saliva.

Evaluation of titanium mesh and fibers in reinforcing endodontically treated molars: An study.

Aim/objective: We aimed to evaluate the fracture resistance of titanium mesh and fibers that could aid as a substitute for crown coverage.

Materials And Methodology: Forty extracted human mandibular molar teeth were selected for this study and were divided into four groups ( = 10). Access cavity preparation was done in all experimental teeth (Groups 2-4) maintaining 1.
