Condition dentin hypersensitivity
Treatments resin-modified glass ionomer cement clinpro xt, glass ionomer cement vidrion r
Phase phase 2/phase 3
Sponsor Federal University of Pelotas
Start date April 2014
End date April 2016
Trial size 20 participants
Trial identifier NCT02378129, UFPel


The aim of this randomized, double-blind, split-mouth clinical trial is to evaluate and compare the desensitizing efficacies of the resin-modified glass ionomer cement ClinproTM XT (3M ESPE, Minnesota, USA) and the conventional glass ionomer cement Vidrion R (SS White, Gloucester, UK) at 2-year follow-up.

Eligibility Criteria

Male or female participants from 28 years up to 70 years old.

Inclusion Criteria: - Male and female subjects between 18 and 70 years old - At least 2 teeth with dentin hypersensitivity in two different hemiarchs - Dental elements with hypersensitivity without any pulp alteration - People who are not taking any medication and women who are not pregnant - Patients without eating disorders or very acidic diets. Exclusion Criteria: - Teeth with hypersensitivity that presented extensive or unsatisfactory restorations, fractures, periodontal alterations, caries lesions, orthodontic brackets, endodontic treatments, pulp alterations. - Subjects who received any desensitizing therapy during the last 3 months - Subjects being under analgesics/anti-inflammatory drugs at the time of the study - Teeth with hypersensitivity and non-carious cervical lesions

Additional Information

Official title Evaluation of the Effectiveness of Dentin Hypersensitivity Treatment Using Glass Ionomer Cements: A Randomized Clinical Trial
Principal investigator Rafael G Lund, PhD
Description Subjects will require to have at least two teeth in different hemiarchs with dentin hypersensitivity. Teeth will be randomized into 2 groups, receiving either Clinpro XT or the conventional glass ionomer cement Vidrion R. Prior to the desensitizing treatment (baseline), painful symptoms will be assessed by tactile and air blast tests using the Visual Analogue Scale (VAS). Treatment evaluations will be conducted up to 2-year post-treatment.
