Efetividade dos agentes químicos no tratamento da hipersensibilidade dentinária em dentes com lesão cervical não cariosa

Abstract

Cervical Dentin Hypersensitivity (CDH) is an increasingly common clinical condition in dentistry. The loss of enamel, cementum and the consequent exposure of the dentinal tubules, cause an exacerbated response to thermal, chemical, tactile and osmotic sensory stimuli in regions of exposed dentin, leading to a painful condition and discomfort to the individual, which may be caused by to non-carious cervical lesions. As a treatment option for this condition, we have surgical, restorative and non- restorative protocols. This study consists of a literature review on the effectiveness of chemical agents in the treatment of cervical dentin hypersensitivity in teeth with non- carious cervical lesions. For this, a search was carried out in the PubMed (Medical Literature Analysis and Retrieval System Online), Scielo (Scientific Electronic Library Online) and ScienceDirect (Elsevier Science's MegaSource) databases, using "Dentin hypersensitivity" AND "non-carious cervical lesion" AND "dentin desensitizing agent", in the period between 2012 and 2022. We found 280 articles published in English and, after excluding the repeated articles and filtering the articles by the inclusion criteria, 24 studies remained eligible to compose the study. According to the studies included in this review, in terms of effectiveness, positive results were observed in the treatment of HD in the use of all the neural, obliterating and mixed chemical agents mentioned in this work. The treatments carried out through the application of fluoride varnishes, which act by obliterating the tubules, and presented results immediately after their use, stood out. With this, it demonstrates that more clinical studies are needed, for longer periods of time to define a methodology that presents greater durability in the use of chemical agents in the treatment of dentin hypersensitivity in teeth with non-carious cervical lesion.
