The effects of different types of surface conditioning methods on enamel demineralization: an in-vitro rebonded bracket study

OpenAlex · İngilizce

Aim: This study aimed to evaluate the effects of the conventional etching and primer (CEP) method andthe self-etching primer (SEP) method on demineralization while rebonding the brackets.Material and Methods: Sixty extracted maxillary first premolar teeth were divided into 4 groups, eachcontaining 15 teeth. The teeth in Groups 1 and 2 were bonded using CEP, and those in Groups 3 and4 were bonded using SEP. After the first bonding, adjacent surfaces of the brackets were measuredusing DIAGNOdent pen, and demineralization values were recorded (T0). The teeth were kept in ademineralization solution for 15 days in a 37°C incubator. Then, all brackets were debonded. The teethin Groups 1 and 3 were rebonded using CEP, and those in Groups 2 and 4 were rebonded usingSEP. In this way, via the enamel surface conditioning prior the first bonding and rebonding, the groupswere constructed as; Group 1 (CEP-CEP), Group 2 (CEP-SEP), Group 3 (SEP-CEP) and Group 4(SEP-SEP). The teeth were kept in the same solutions by same way (T1). The Kolmogorov-Smirnovtest was used to determine whether or not the data were normally distributed, the Wilcoxon test wasused for comparisons within groups, and the Mann-Whitney U and Kruskal-Wallis tests were used forcomparisons between groups. p
