Caracterização Metodológica dos Estudos In Situ sobre Erosão Dentária: Uma Abordagem Atual

Abstract

Objective: To characterize the methodology of studies on dental erosion. Material and Methods: Literature searches were carried out the databases Scopus and PubMed, using the descriptor erosion, the term in situ and the Boolean operator AND. The survey instrument consisted of a form containing the following variables: author, country where the research was performed, publication year, type of sterilization of the specimens; prior preparation of the tooth surface; analysis of tooth wear; origin, tissue and type of tooth; dentition; substance, pH and quantity of the demineralization/chelating solution; duration of the erosive challenge; number of volunteers and study length. Results: A total of 26 manuscripts were selected. The biological material mostly used was of human origin (69.23%), of which 100% corresponded to enamel. Teeth sterilization was carried out preferably with ethylene oxide (26.9%). The immersion 150ml, soft drink, 4 times/day and 5min were the most frequent choices for the erosive challenging. The pH values ranged from 1.0 to 3.8. Preventive measures by the use of fluorides or presence of acquired pellicle on the specimens’ surface were observed 80.76% of the articles. Profilometry and microhardness were the most commonly used tests to assess dental erosion. Conclusion: The most applied methodology consisted of human teeth sterilized with ethylene oxide exposed to soft drinks, evaluated by means of profilometry and microhardness tests. DESCRIPTORES: Tooth erosion. Methods. Clinical trial.
