Clinical Trial Summary

The present study was designed as a randomised controlled clinical trial which was unicenter, double-blinded, parallel designed study, according to the Consolidated Standards of Reporting Trials (CONSORT) criteria, 2010. The study period was from July 2014 to September 2015.

Description:

90 Patients visiting the Out Patient of Department of Periodontology, Krishnadevaraya College of Dental Sciences and Hospital, Bengaluru, India, presenting with a chief complaint of dentinal hypersensitivity were enrolled in the study. Patients' age ranged from 18-60 years. The subjects interested in participating were explained in detail the treatment protocol. A verbal consent as well as a written informed consent was obtained from each patient Treatment of dentinal hypersensitivity with a combination of diode laser and potassium nitrate desensitising agent was considered as the test group and this was compared with diode lasers alone and desensitising agent alone as the positive control groups. The study was conducted in full accordance with the declared ethical principles (World Medical Association Declaration of Helsinki, version VII, 2013)13 and was approved by the Institutional review board of Krishnadevaraya College of Dental Science and Hospital, under the registration number of (ACA/DCD/SYN/KCODS - B/PG/2013-2014).

Intervention

Procedure:
• Fluorosed Group
A single episode of laser therapy with without potassium nitrate (RA Thermoseal*) desensitising agent application was administered to the patients, A group only with desensitising paste and A group with desensitising paste and laser treatment depending on the study group they were assigned
• Non Flourosed Group
A single episode of laser† therapy with or without potassium nitrate (RA Thermoseal*) desensitising agent application was administered to the patients, depending on the study group they were assignedGROUP 2B: Patients with healthy non fluorosed teeth receiving diode laser treatment$. (n=15)GROUP 2C: Patients with healthy non fluorosed teeth receiving diode laser + desensitising agent (potassium nitrate- RA thermoseal**) treatment.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Reduction in hypersensitivity	The primary outcome that was assessed in the study was the reduction in dentinal hypersensitivity sensation. The visual analogue scale was used as a recording scale when tested with the tests for hypersensitivity, which were the testing with a blast of air, ice cold water testing and electrical tactile sensitivity testing using a scratch-o-meter.	30 minutes
Secondary	use of diode laser in reducing hypersensitivity	Efficacy of treatment when diode laser is used alone as a treatment option after scaling and root planing.	30 mins
Secondary	use of desensitising agent alone	Efficacy of treatment when desensitising agent was used as monotherapy after scaling and root planing	30 minutes
Secondary	combination of densensitising agent and diode laser	3. Efficacy of treatment when a combination of diode laser and desensitising agent was used after scaling and root planing, for the treatment of dentinal hypersensitivity.	30 minutes
