Prevalence Of Middle Mesial Canals And Isthmi In Mandibular First And Second Molars In A Tabriz Subpopulation Using Cone Beam Computed Tomography
Having knowledge of root canal morphology is a crucial requirement for effective treatment. Taking into account the impact of factors such as age, gender, and race on the diversity of root canals in teeth, this study aimed to investigate the prevalence of middle mesial (mid-mesial) canals and isthmus in mandibular first and second molars in a specific subpopulation of Tabriz patients. Cone-beam computed tomography (CBCT) was used for this investigation.
CBCT radiographs of 215 patients were examined to determine the presence of the mid-mesial canal and isthmus in mandibular first and second molars without endodontic treatment based on gender. All samples were obtained from the Faculty of Dentistry, Tabriz University of Medical Sciences, in 2019. The obtained results were analyzed using SPSS version 16, employing a chi-square test (P < 0.05).
On the left mandibular side, twenty-eight samples (13%) exhibited a mid-mesial canal in both the first and second molars. On the right side, these values were 29 (13.5%) and 47 (21.9%) for the first and second molars, respectively. Regarding the frequencies of isthmus in mandibular first and second molars, the values were 2 (0.9%) and 18 (8.4%) on the right side and 5 (2.3%) and 21 (9.8%) on the left side, respectively (P-values = 0.147, P = 0.938, P = 0.193, and P = 0.713 in left first, left second, right first, and right second mandibular molars, respectively, which were insignificant).
This study revealed a low prevalence of mandibular first and second molars with mid-mesial canal and isthmus. The left and right sides and gender did not influence this prevalence.
