Comparative study of the degree of apical microleakage between two different endodontic sealing cements

Abstract

Introduction. Considering that the main cause of failure in endodontics is due to bacterial contamination or their products inside the root canals due to apical microleakage, endodontic sealing cements play an important role for a hermetic and safe obturation. In recent years, the use of MTA Fillapex and Adseal has become more widespread, and their physicochemical and biological properties have also been the subject of recent studies. Objective. To compare the degree of apical microleakage of two different endodontic sealing cements in filled dental roots. Materials and methods. The study is comparative, cross-sectional, observational and quantitative. The analysis units were dental roots of extracted single-rooted pieces and straight roots of molars sealed with
MTA Fillapex and Adseal cements. The sample consisted of 60 roots. Results. Regarding the comparison between the different samples of MTA Fillapex and Adseal, it was found that, according to the sealing degree, the MTA Fillapex generated 11 samples with sealing degree 1, 5 samples with degree 2 and 2 samples with degree 3. The Adseal cement produced 18 samples with sealing degree 1 and 2 samples with sealing degree 2. Through inferential data analysis, the use of non-parametric tests was chosen. In this case, the test used was the Mann-Whitney U test, where a p-value of significance of 0.008 was obtained. Conclusion. It is concluded that there are significant differences between Adseal and MTA Fillapex cements in terms of apical microleakage.
