Clinical Trial Summary

This study will compare clinically the efficacy, time to action and duration of different treatments for patients with non-carious cervical lesions (NCCLs) that caused dentin hypersensitivity (DH).


Description:

This study will compare clinically the efficacy, time to action and duration of different treatments for patients with non-carious cervical lesions (NCCLs) that caused dentin hypersensitivity (DH). Casuistic and methods: 60 participants with NCCLs and positive for DH will be enrolled in the study to receive randomly the followed treatments: LA= 780 nm and 70mW GaAlAs Laser/ 4 sessions; LAP= placebo laser/ four sessions; RGI= ClinproTM XT Varnish/ in-office single session; RX= adhesive RelyXTM Arc/ in-office single session; DE= stannous fluoride dentifrice/30-days-home-use; DE-P= placebo dentifrice/30-days-home-use. Pain from DH is measured with visual analogue scale (VAS), pre-treatment and in accordance with each treatment, immediately after the end of the treatment (S1); one and two weeks (1S and 2S) and one and two months (1M and 2M) after the end of the treatments. Strategies of treatments are compared each other in each period of evaluation and along time with pre-treatments values of pain, using Kruskall-Wallis and Friedman Test (p<0.05).

Outcome

Type Measure Description Time frame Safety issue
Primary pain from dentin hypersensitivity (DH) Examiner assess dentin hypersensitivity (DH) using VAS (visual analogue scale). The selected tooth was thermic stimulated by a cold air (approximately 10°C) from a triple syringe placed 3mm from the buccal surface in the cervical area, perpendicular to the tooth long axis at full blast during 3 seconds. In addition, the selected tooth received a mechanical stimulus by a dental probe n° 05 over the cervical area. Thereby, volunteers were instructed to record the sensitivity perception by placing a mark on the scale from 0 (no pain) to 10 (intolerable pain) while sensitivity test was occurred pre-treatment
