Room: Exhibit Hall

Objective: The aim of this study was to assess the root canal configurations in permanent mandibular central incisors (PMCIs), permanent mandibular lateral incisors (PMLIs), permanent mandibular first premolars (PMFPs) and the correlation with the appearance of distolingual root (DLR) in permanent mandibular first molars (PMFMs) using cone-beam computed tomography (CBCT) imaging. Methods:A total of 400 patients’ CBCT images were included. The prevalence and distribution of DLR in PMFMs along with root canal configurations of PMCIs, PMLIs and PMFPs were assessed. Multivariable logistic regression and partial correlation analysis were used to evaluate the correlation between the root canal configurations of PMCIs, PMLIs, PMFPs and PMFMs with DLR. Results: The prevalence of PMFMs with DLR was 23.0%, the incidence of complicated root canal configurations in PMCIs, PMLIs, PMFPs were 15.6%, 25.1% and 25.9%, respectively. The most prevalent complicated root canal anatomical type in PMCIs and PMLIs were Vertucci's Type III, and PMFPs in Vertucci's Type V. The incidence of complicated root canal configurations in PMCIs, PMLIs and PMFPs were both correlated to the presence of PMFMs with DLR (p<0.001). After adjusting for categorical variables including gender, age, and side, the correlation coefficient for PMCIs, PMLIs and PMFPs were 0.153 (p<0.001), 0.203 (p<0.001) and 0.304 (p<0.001). Conclusions: The gradually increasing correlation between PMFMs with DLR and PMCIs, PMLIs, PMFPs with complicated root canal morphology is prominent in Taiwanese individuals. Clinicians should be aware of root canal variants and correlation before endodontic treatment.

We devoted to clinical study by analyzing cone-beam computed tomography (CBCT) images. In addition, we are the first group to regard mandibular first molars with distolingual root as a factor to correlate other permanent teeth with complicated root canal morphology. Furthermore, we have some research performance published in Journal of Endodontics.
