Comparative evaluation of microhardness of dentin treated with 4% titanium tetrafluoride and 1.23% acidic phosphate fluoride gel before and after exposure to acidic pH: An study.

Aim: The aim of this study was to comparatively evaluate the effect of 4% titanium tetrafluoride (TiF4) and 1.23% acidic phosphate fluoride (APF) gel on the microhardness of human coronal dentin.

Materials And Methods: Thirty noncarious extracted premolars were collected and sectioned buccolingually with the help of diamond disk.

Shear bond strength evaluation of adhesive and tooth preparation combinations used in reattachment of fractured teeth: an ex-vivo study.

Objectives: The objectives of this study were to evaluate the bond strengths of different adhesive materials, different tooth preparation designs and adhesive tooth preparation combinations to reattach fractured incisor fragments.

Materials And Methods: The study sample comprised 48 intact human maxillary central incisors divided into two groups A and B. The incisal third was sectioned with a diamond disc.
