Abstract

Introduction: Dental bleaching is one of the most frequently performed procedures in dentistry nowadays due to the fact that there is increasing awareness of dental appearance, although this treatment improves esthetics and the quality of patients’ life, there are some side effects, being the most frequent tooth sensitivity, which is an unpleasant factor for the patient. Objective: To identify the prevalence of tooth sensitivity after bleaching treatment. Materials and methods: In the present study of a systematic review type, a search was carried out for RCT scientific articles using meta-search engines such as PubMed, Elsevier and Google Scholar. 31 articles were used for data collection, only those studies that were available in Spanish and English, published between the years 2000 – 2020, were selected. Results: Five determinant aspects of TS were analyzed resulting that the sensitivity is equal in home and clinical bleaching. that drugs are not able to prevent TS unlike the previous use of desensitizers; the highest grade of sensitivity recorded is the moderate one. Finally, the highest TS was observed after 1 hour of bleaching treatment. Conclusion: Due to the fact that the origin of tooth sensitivity induced by bleaching treatment is still unknown; it’s not possible to determine an exact prevalence since many factors could influence it.
