Comparative evaluation of diode laser, stannous fluoride gel, and potassium nitrate gel in the treatment of dentinal hypersensitivity.

The aim of the present study was to compare the efficacy of diode laser (DL) with stannous fluoride and potassium nitrate gels in the treatment of dentinal hypersensitivity (DH). Fifty-four subjects, ages 25-45, having 2 adjacent teeth sensitive to air blast stimulation were included. The subjects were divided randomly into 3 groups (n= 18): Group A, subjects treated with DL; Group B, subjects treated with 0.

Comparison of radiovisiography and digital volume tomography to direct surgical measurements in the detection of infrabony defects.

Objectives: To compare the linear measurements of Radiovisiography (RVG) and Digital volume tomography (DVT) to direct surgical measurements in the detection of periodontal infrabony defects.

Study Design: RVG and DVT images were taken prior to periodontal surgery for 28 infrabony periodontal defects. After defect debridement, direct bony defect measurements were made from the cemento enamel junction (CEJ) to the base of the defect (CEJ-BD) and to the alveolar crest (CEJ-AC) with a periodontal probe.
