摘要： 目的:探讨改良式硅橡胶印模定位平行投照技术的临床运用。方法:选取24例牙周炎牙周治疗患者及24例牙体牙髓科根管治疗的患者,分别进行硅橡胶印模定位平行投照和分角线投照,分别测量数字式根尖片上沿牙长轴方向的牙体长度(L)及釉牙骨质界牙体宽度(W), 按照牙位分为前牙+上颌磨牙组和下颌磨牙组,使用SPSS 22.0软件进行配对t检验及相关性分析比较2种投照技术2次投照的差异。结果:虽然两种投照技术前后2次投照的牙体长度及宽度的配对t检验均不具有显著性差异(P>0.05), 但是与分角线投照技术相比,改良式硅橡胶印模定位平行投照技术所得到的前后两次根尖片上的牙体长度和宽度的组内相关系数更高。结论: 改良式硅橡胶印模定位投照技术是一种稳定可靠、可操作性强的根尖片投照技术,适用于需要进行纵向定量对比的各类口腔科疾病诊断和分析。

Abstract: Objective: To explore the application of silicone rubber impression positioning paralleling technique in clinic practice. Methods: 24 periodontitis patients needed repair of periodontal bone defects and 24 endodontic patients needed root canal treatment were performed silicone rubber impression positioning paralleling technique and bisecting-angle technique respectively. The length of the tooth along the long axis of the tooth and the width of tooth at enamelo-cemental junction were measured on the digital periapical radiograph,which were divided into anterior teeth + maxillary molar group and mandibular molar group. Paired t test and reliability test was used to compare the differences and correlations of the periapical radiograph before and after treatment, SPSS 22.0 was used for analysis. Results: Although there was no significant differences of the length and width on periapical radiograph before and after treatment using paired t-test(P>0.05), compared with the bisecting-angle technique, the silicone rubber impression positioning paralleling technique showed stronger correlation, which suggested silicone rubber impression positioning paralleling technique was more stable. Conclusion: The silicone rubber impression positioning paralleling technique is reliable, stable, and relatively simple technique. It is suitable for the diagnosis and analysis of various dental diseases requiring longitudinal quantitative comparison.
