Efficacy of ozonated water over chlorhexidine mouth rinse in chronic gingivitis patients - A comparative clinical study.

Aim: This study aimed to compare the efficacy of ozonated water mouth rinse over chlorhexidine mouth rinse against the accumulation of plaque in chronic gingivitis patients.

Materials And Methods: A total of 30 patients with chronic generalized gingivitis were choosen for the study. The duration of this study was 15 days and was divided into three groups.

Comparative efficacy of coronally advanced flap with and without guided tissue regeneration in the management of gingival recession defects: A split-mouth trial.

Background: The gingival recession causes tooth sensitivity, poor esthetics, and tooth mobility in severe cases. Scientific documentation revealed effective root coverage (RC) and increased keratinized tissue heights acquired with the coronally advanced flap (CAF) for multiple recession defects.

Objectives: This research evaluates and compares the efficacy of CAF procedures with and without Type I collagen bio-absorbable membrane in guided tissue regeneration (GTR) in the treatment of Miller's Class I and II gingival recession.

Photoinduced Charge Transfer and Trapping on Single Gold Metal Nanoparticles on TiO.

We present a study of the effect of gold nanoparticles (Au NPs) on TiO on charge generation and trapping during illumination with photons of energy larger than the substrate band gap. We used a novel characterization technique, photoassisted Kelvin probe force microscopy, to study the process at the single Au NP level. We found that the photoinduced electron transfer from TiO to the Au NP increases logarithmically with light intensity due to the combined contribution of electron-hole pair generation in the space charge region in the TiO-air interface and in the metal-semiconductor junction.
