Periapical Lesions and Missed Canals in Endodontically Treated Teeth: A Cone-Beam Computed Tomographic Study of a Chinese Subpopulation
BACKGROUND: Periapical lesions (PL) are a common complication of endodontically treated teeth (ETT), which can result from a missed canal (MC). This study aimed to assess the prevalence of PL and MC in the ETT of a Chinese subpopulation and investigate potential associations between them. MATERIAL/M...

Sumario: | BACKGROUND: Periapical lesions (PL) are a common complication of endodontically treated teeth (ETT), which can result from a missed canal (MC). This study aimed to assess the prevalence of PL and MC in the ETT of a Chinese subpopulation and investigate potential associations between them. MATERIAL/METHODS: A total of 561 cone-beam computed tomography images were selected and analyzed. A total of 1024 endodontically treated posterior teeth excluding third molars were evaluated for the presence of PL and MC. The chi-square test or Fisher’s exact test, as well as the odds ratio test, were used to determine whether there was an association and risk relationship between the incidence of PL and the occurrence of MC. RESULTS: The overall prevalence of PL and MC in ETT was 56.1% and 19.0%, respectively. In endodontically treated molars, the incidence of PL and MC was 64.1% and 27.6%, whereas in premolars, it was 42.1% and 4.27%. The maxillary first molar showed the highest frequency of PL (71.5%) and MC (65.7%), with the mesiobuccal second canal being the most missed (78.8%). Teeth with an MC were found to be 3.658 times (95% confidence interval=2.541–5.301, P<0.0001) more likely to be associated with a PL. CONCLUSIONS: Endodontically treated teeth with missed canals are associated with higher risks of periapical lesions. The high prevalence of these complications in a Chinese subpopulation underscores the importance of implementing enhanced diagnostic and treatment methods for root canal treatment or retreatment. |
