Eficácia de diferentes agentes dessensibilizantes no tratamento da hipersensibilidade dentinária: uma revisão integrativa

Abstract

Dentin hypersensitivity (DH) is a pathological process characterized by acute and short-term pain, of multifactorial etiology, closely related to non-carious cervical lesions and which impacts patients' quality of life. This study aimed to search for scientific evidence regarding the effectiveness of different chemical and physical desensitizing agents, isolated and combined, in controlling dentin hypersensitivity associated with non-carious cervical lesions. For this, a search was carried out for randomized clinical studies, in English or Portuguese, published in the last 10 years, in the databases PubMed (Medical Literature Analysis and Retrieval System Online) and Portal de Periódicos da CAPES (Coordenação de Aperfeiçoamento de Emprego of Superior Level), encompassing the Scielo (Scientific Electronic Library Online), Web Of Science, PubMed and PubMed Central databases, using as descriptors ‘’hypersensitivite non-carious cervical lesions’’ OR ‘’cervical dentin hypersensitivity’’ AND ‘’clinical trial’’. A total of 270 references, after removing duplicates and filtering by the inclusion and exclusion criteria, 22 eligible studies remained. HD. Potassium oxalate proved to be effective in all studies that involved it. With regard to physical agents, the most researched is the low-power laser, this proves to be effective, but its effect can be enhanced when associated with the laser of high potency or combined with chemical agents based on glutaraldehyde or potassium oxalate. In short, it can be concluded that all researched agents are effective in the treatment of HD, but the durability is still not well defined. The combination of agents can be an effective alternative, in particular, protocols that combine laser therapy with a chemical agent, in addition, more long-term studies are needed, with larger samples, so that in the near future, the specific therapy for each case will be precisely and faithfully indicated.
