An In-vitro Comparison of Nano Hydroxyapatite, Novamin and Proargin Desensitizing Toothpastes - A SEM Study.

Introduction: Dentinal Hypersensitivity (DH) is commonly encountered clinical condition in dental practice which affects 8-57% of the adult population presenting for dental treatment, but the treatment of the same remains doubtful.

Aim: The purpose of this study was to evaluate and compare the effects of three different desensitizing agents (15% nano hydroxyapatite crystals; 5% novamin and 8% proargin) on dentinal permeability and tubule occlusion in-vitro. Scanning Electron Microscope (SEM) was used to evaluate the effect of these commercially available desensitizing toothpastes.

Amnion and Chorion Allografts in Combination with Coronally Advanced Flap in the Treatment of Gingival Recession: A Clinical Study.

Background: Guided tissue regeneration (GTR) based root coverage using different allograft membranes has been utilized to correct gingival recession defects with promising results. Amnion and chorion allograft membranes of alternative origin derived from human placental tissue has been advocated in the treatment of gingival recession. However, chorion membrane has been used in combination with amnion membrane no study has compared these allograft membranes in the treatment of gingival recession.
