Abstract:
Objective To explore the application value of cone beam computed tomography(CBCT)for the analysis of influencing factors of the nutrient canals(NCs)of the mandible.Methods The CBCT imaging data of 234 patients who attended some center's stomatology department from April 2021 to April 2024 were analyzed retrospectively,including 120 patients with periodontitis(enrolled into a periodontitis population group)and 114 periodontally normal persons(divided into a periodontally normal population group).The periodontitis population group was categorized into Subgroup 1(resorption length≤1/3 root length),Subgroup 2(1/3 root length0.05).The three subgroups were significantly different in the detection rate of mandibular NCs(P<0.05),and statistical differences were also found between Subgroup 1 and 2 and between Subgroup 1 and 3 in the detection rate of mandibular NCs(P<0.05),while not found between Subgourp 2 and 3(P>0.05).The relevant influencing factors on the mandibular NCs included age(OR=1.069,P<0.001)and having periodontal disease(OR=0.154,P<0.001).Conclusion CBCT is of great significance for evaluating the relationship between mandibular NCs and alveolar bone resorption.[Chinese Medical Equipment Journal,2025,46(7):51-55]
