The Distribution of Missing Canals in Single-Rooted Teeth with Two Canals

Objective: To determine whether the missing canals in endodontically treated single-rooted teeth with two-canals are present either buccal or lingual/palatal for Turkish subpopulation. Methods: High-quality cone-beam computed tomography scans of 1297 belonging to 782 adults over age 18 were obtained from archive a dental clinic. Within this dataset, 129 had undergone endodontic treatment and possessed two canals, indicating absence one canal. These cases included 73 mandibular anterior teeth, 29 premolars, 27 maxillary second premolars. We carefully documented both tooth type location classify canal as independent, we required it have separate orifice other be connected within 5 mm its unsealed apex. The differences between categorical variables tested Chi-square analysis. P≤0.05 was chosen statistical significance level. Results: statistically more often premolars than similar (p=0.001). incidence lingual teeth; higher compared Overall, most frequently missed premolar (96.6%). Conclusions: prevalence is whereas encountered It essential clinicians aware these potential morphological variations enhance success root treatment.
