Methods: In total, 104 lesions in the anterior maxilla were assessed. The localisation of CS termination points on the alveolar crest was evaluated. Subsequently, the consistency of the CS and CS-lesion relationships were determined based on the maximal diameter of the lesion and the presence of a cortical perforation. Results: Of the 104 lesions, 82 (78.8%) exhibited at least one CS. The presence of CS was statistically significantly different based on the diameter of the lesion (P <0.001). When the presence of CS was investigated in relation to cortical perforation status, a significant difference was observed (P <0.05). Anatomically, CS was most common in the central incisor and ended most frequently near the crest apex vertically and in the palatal region horizontally. Among the instances of CS, 55.3% were lesion-related, 22.3% were in contact and 23 (22.3%) were unrelated to the lesion. Conclusion: The incidence of CS was high in anterior maxillary pathological lesions and even higher in small-sized pathological lesions. Most CSs were located within or next to the surgical margin of the pathological lesion.eninfo:eu-repo/semantics/closedAccesscanalissinuosusCBCTmaxillaoral surgerypathological lesionArticle2821311374049776610.3290/j.cjdr.b6260624WOS:001511313800005Q4
