Quantification and Comparison of the Impact of the Smoking Status on Oral Polymorphonuclear Leukocyte and Malondialdehyde Levels in Individuals with Chronic Periodontitis: A Double-Blinded Longitudinal Interventional Study.

Background: The formation of reactive oxygen species by oral polymorphonuclear leukocytes (oPMNs) is amplified in smokers with chronic periodontitis (CP) causing tissue damage which can be measured by quantifying levels of malondialdehyde (MDA).

Objective: To quantify and compare the impact of smoking status on oPMN and MDA in individuals with CP before and after scaling and root planing (SRP).

Materials And Methods: Sixty individuals were divided into four groups, namely, periodontally healthy (Group A), current smokers with CP (Group B), former smokers with CP (Group C), and nonsmokers with CP (Group D).

Platelet derived growth factor-BB levels in gingival crevicular fluid of localized intrabony defect sites treated with platelet rich fibrin membrane or collagen membrane containing recombinant human platelet derived growth factor-BB: A randomized clinical and biochemical study.

Background: Development of autologous and recombinant growth factor/matrix combination products represent a new emerging trend in regenerative therapeutics and have gained increasing attention as a strategy to optimize tissue regeneration. The aim of the present study was to evaluate the levels of platelet derived growth factor-BB (PDGF-BB) in gingival crevicular fluid (GCF) during early healing period after the regenerative treatment of intrabony defects using beta tricalcium phosphate (β-TCP) as a bone regeneration material with either platelet rich fibrin (PRF) membrane or collagen membrane (CM) treated with recombinant human PDGF-BB (rhPDGF-BB).

Methods: Twenty patients (13 males and 7 females) with chronic periodontitis participated in this prospective, randomized clinical and biochemical study.

Efficacy of Two Pre-Procedural Rinses at Two Different Temperatures in Reducing Aerosol Contamination Produced During Ultrasonic Scaling in a Dental Set-up - A Microbiological Study.

Aerosol has been considered one of the main concerns in the dental community because of possible risk of infection transmission. Antiseptics used in the form of pre-procedural rinses can reduce aerosol contamination during dental procedures. The aim of this study is to evaluate and compare the efficacy of 0.

Effects of two desensitizing dentifrices on dentinal tubule occlusion with citric acid challenge: Confocal laser scanning microscopy study.

Background: Dentin hypersensitivity results when patent tubules are exposed to pain-inducing external stimuli.

Aim: This study aims to compare the effects of two desensitizing dentifrices containing NovaMin and arginine on dentinal tubule occlusion with and without citric acid challenge in vitro using confocal laser scanning microscopy (CLSM).

Materials And Methods: Forty dentin discs were randomly divided into Groups I and II containing twenty specimens each, treated with NovaMin and arginine-containing dentifrices, respectively.

Effect of Pre-Procedural Chair-Side Finger Stretches on Pinch Strength amongst Dental Cohort- A Biomechanical Study.

Introduction: Ergonomics is the essential principle behind the health and successful practice for a dentist and dental hygienist. During the procedure of dental Scaling and Root Planing (SRP), a high level of pinch force is exerted by the finger muscles resulting in early muscle fatigue.

Aim: This pilot study comparatively evaluated the Pinch Strength (PS) of the finger muscles, prior to and after SRP, amongst dental cohort performing chair-side hand and finger stretches to those not performing the same.
