摘　　要：目的:综合分析锥形束CT(CBCT)在门诊口腔临床诊断和治疗中的应用。方法:收集2012年3月-2014年8月,在本院口腔门诊应用锥形束CT检查的患者6810例,年龄为4-89岁,对其辅助诊断、指导治疗的意义进行分析。结果:复杂下颌第三磨牙阻生经CBCT定位(3465例,50.88%);缺失牙患者经CBCT设计行缺牙种植修复(1856例,27.25%);牙列畸形通过CBCT行埋伏牙导萌术定位(538例,7.90%);牙体牙髓病经CBCT检查明确复杂根管的走形、牙根折裂早期诊断(501例,7.36%);慢性牙周炎经CBCT检查评估病变牙槽骨的吸收范围(265例,3.89%);颞下颌关节病(TMD)(112例,1.65%);外伤患者经CBCT检查发现颌骨骨折(40例,0.59%);颌下腺导管肿胀经CBCT检查发现并明确定位阳性结石(33例,0.48%)。结论:CBCT技术广泛应用于口腔门诊的临床诊疗过程中,有助于进行辅助诊断和制定诊疗方案、规避手术风险,在提高门诊临床诊疗的安全性、精确性等方面具有重要的参考价值,值得进一步推广应用。Objective：To comprehensively analyze the applications of cone-beam CT（CBCT） in diagnosis and therapy in the outpatient clinic. Methods： A total of 6810 patients receiving CBCT examination, aged 4 to 89 years old, were selected from the department of stomatology during March 2012 to August 2014. Results： 3465 patients（50.88%） with mandibular third molars were evaluated by CBCT.1856 patients（27.25%） with missing teeth received dental implant restorations by CBCT design. 538 patients from pediatric dentistry and orthodontics（7.90%） were assessed exactly by CBCT examination to help guide and expose the impacted teeth. The complex root canal morphology was clearly demonstrated by CBCT analysis in 501 cases（7.36%）, showing its helpfulness for early diagnosis. 265 patients（3.89%） with chronic periodontitis identified by the absorption of alveolar bone were confirmed by CBCT. 112 cases of temporomandibular joint disorders（TMD）（1.65%） and 40 cases of the jaw bone fracture（0.59%） due to trauma were found through the CBCT examination. 33 patients（0.48%） with swollen submandibular duct were clearly diagnosed, in which caseradiopaque calculus could be identified. Conclusion：CBCT technology can be widely used in dental care for diagnosis and clinical treatment. It is helpful for the dentist to make a diagnosis, design a treatment plan, and to avoid risks of thesurgery. Furthermore, it can give adjunctive information to improve the diagnosis and treatment efficacy, and thus is worthy of further application.
