Application of microcomputed tomography for quantitative analysis of dental root canal obturations

Journal Title: Advances in Hygiene and Experimental Medicine - Year 2014, Vol 68, Issue

Abstract

Introduction: The aim of the study was to apply microcomputed tomography to quantitative evaluation of voids and to test any specific location of voids in tooth’s root canal obturations. Materials and Methods: Twenty root canals were prepared and obturated with gutta-percha and Tubli-Seal sealer using the thermoplastic compaction method (System B + Obtura II). Roots were scanned and three-dimensional visualization was obtained. The volume and Feret’s diameter of I-voids (at the filling/dentine interface) and S-voids (surrounded by filling material) were measured.Results: The results revealed that none of the scanned root canal fillings were void-free. For I-voids, the volume fraction was significantly larger, but their number was lower (P = 0.0007), than for S-voids. Both types of voids occurred in characteristic regions (P < 0.001). I-voids occurred mainly in the apical third, while S-voids in the coronal third of the canal filling.Conclusions: Within the limitations of this study, our results indicate that microtomography, with proposed semi-automatic algorithm, is a useful tools for three-dimensional quantitative evaluation of dental root canal fillings. In canals filled with thermoplastic gutta-percha and Tubli-Seal, voids at the interface between the filling and canal dentine deserve special attention due to of their periapical location, which might promote apical microleakage. Further studies might help to elucidate the clinical relevance of these results.
