Examination of root canal morphology of teeth affected by Molar Incisor Hypomineralization (MIH): Frequency of accessory canals

Abstract

Aim: The aim of this study was to investigate the incidence of the presence of accessory canals in the root canal of the maxillary first molar teeth affected by Molar Incisor Hypomineralization (MIH). Methodology: A total of 12 maxillary first molar teeth affected by MIH were obtained from 10 children aged from 10 to 12 years. The frequency of the presence of accessory canals was examined by using microcomputed tomography and 3D image software. Results: Accessory canals were observed in the mesiobuccal (MB) canal in all of the samples with a statistically significant difference (p
