This study was done to assess the influence of the topical application of two different desensitizing agents on dentin permeability and dentinal tubule occlusion. Twenty-one rats provided 84 teeth: 36 for the in vitro and 48 for the in vivo investigation. The following agents were tested: Group 1, 2% potassium nitrate plus 2% sodium fluoride gel; Group 2, 5% sodium fluoride varnish; Group 3, 3%...

Introduction: Dentin hypersensitivity (DH) is a commonly encountered dental complaint, management of which often challenging to dentists. It occurs when dentinal tubules are patent both at the pulpal and oral surface. widely accepted that DH affects function quality life. Thus, it necessary for dentists manage properly. Objective: The objective this study was assess efficacy VivaSens Propolis i...

The aim of this study was to determine the action of desensitizing materials on bovine dentin. Four extracted healthy bovine molars were selected out of which 5 blocks from cervical region of each tooth were obtained, resulting in a 5x5mm final area. To compose the negative control group (group B), the samples were separated and not submitted to any treatment. For the positive control (Group A)...

BACKGROUND Dentin desensitizers may change the properties of smear layer and have adverse effects on the bonding performance of adhesive systems. AIM The aim of this study was to compare the effect of bioactive glass (BG), hydroxyapatite, and diode laser desensitization on shear bond strength of resin composites to dentin at different time intervals. MATERIALS AND METHODS Seventy-two caries...
