Low-level Laser Therapy in Combination with Desensitising Agent Reduces Dentin Hypersensitivity in Fluorotic and Non-fluorotic Teeth - A Randomised, Controlled, Double-blind Clinical Trial.

Purpose: Dentin hypersensitivity (DH) is a prevalent painful condition of the teeth, the management of which lies in the obliteration of patent dentinal tubules. The purpose of this study was to compare the efficacy of 5% potassium nitrate (PN), low-level laser therapy (LLLT), and combination of low-level laser therapy and 5% potassium nitrate (LLLT+PN) in patients with fluorotic and non-fluorotic hypersensitive teeth.

Materials And Methods: Ninety self reporting patients with DH completed the randomised, double-blind study.

Dental unit water lines decontamination with the aid of nanotechnology.

Aim: This article reviews the issue of dental unit waterline (DUWL) contamination which affects all the clinical and hospital settings. The contaminating microorganisms commonly isolated from these settings and the most pathogenic among them have serious consequences. Over the years several measures are inculcated for decontamination of water, their advantages and shortcomings have been addressed.

Analysis of matrix metalloproteinase-8 levels in gingival crevicular fluid and whole mouth fluid among smokers and nonsmokers using enzyme-linked immune-sorbent assay and a novel chair-side test.

Aim: To indigenously prepare a chair-side test kit for investigating and comparing the matrix metalloproteinase (MMP)-8 levels in gingival crevicular fluid (GCF) and saliva in patients with healthy periodontium, gingivitis and chronic periodontitis in smokers and nonsmokers. To validate the diagnostic accuracy of indigenously prepared chair-side test against enzyme-linked immune-sorbent assay (ELISA). Furthermore, to assess the effect of nonsurgical periodontal therapy (NSPT) on the levels of MMP-8 in GCF and saliva among the test groups.
