Extrusion of Root Canal Filling Materials in Molars of a Turkish Subpopulation

Abstract

Aim This research aimed to investigate the root canal filling sealer or gutta-percha extrusion in molars in a population in Turkiye. Material and method Cone-beam computed tomography images of 831 endodontically treated molars (284 maxillary first molars, 189 maxillary second molars, 178 mandibular first molars, and 180 mandibular second molars) were examined at three planes by two endodontists. The presence of extrusion, the number of teeth, and the type of molar were determined via the chi-square test at a p-value of 0.05 in SPSS V25 (IBM, Chicago, IL). Results 13.71 % of the molars had extrusion of root canal filling materials. In maxillary and mandibular molars, extrusion was observed in 17.5% and 8.7% of cases, respectively. Extrusion was seen in 15.8% of maxillary first molars, 20.1% of maxillary second molars, 8.4% of mandibular first molars, and 8.9% of mandibular second molars. Conclusion Root canal filling material extrusion was statistically detected more in maxillary molars than in mandibular molars. Extrusion was more observed in maxillary second molars than in other molar categories.
