目的：对树脂包覆技术进行间接修复进行了大量的研究，并报道了其疗效。本研究对牙本质树脂涂层技术在预备牙体后的临床过程进行了研究，并对该技术的临床效果进行了检验。方法：对2014年9月至2019年10月期间在三家合作牙科诊所中的一家就诊的18例患者中的20例进行评估。采用树脂涂层技术，在嵌体空腔制备后应用薄涂层材料（Hybrid CoatⅡ，HCⅡ）进行治疗。患者的牙科和医疗记录以及临床信息，包括牙齿部位、手术、使用的材料以及手术前后和召回时的临床症状，均采用既定的临床评估标准获得。结果：前磨牙修复率为50%，磨牙修复率为50%。除一例外，其余病例均采用局麻。40%的病例单独使用HCⅡ进行树脂涂层，60%的病例使用HCⅡ与可流动树脂联合进行树脂涂层。19例患者，95%的患者术后预后良好。在治疗前冷水刺激疼痛的10例（50%）患者中，9例预后良好；然而，在一个病例中，饮用冷水后疼痛持续存在，患者随后出现牙髓症状，因此需要切除牙髓。结论：HCⅡ树脂包覆技术在嵌体空腔制备中的临床应用效果良好。
Purpose: Many studies have been conducted on the resin-coating technique for indirect restorations, and its efficacy has been reported. This study investigated the clinical course of cases with the resin-coating technique for dentin after inlay cavity preparation and examined the efficacy of the technique clinically.Methods: Twenty cases in 18 patients visiting one of three dental clinics that were collaborating with this investigation between September 2014 and October 2019 were evaluated. The patients were treated using the resin-coating technique by applying a thin coating material (Hybrid Coat Ⅱ, HC Ⅱ) after inlay cavity preparation. Patient dental and medical records as well as clinical information that included tooth site, procedures, materials used, and clinical symptoms before, during, and after the procedures and at the time of recall were obtained using set clinical evaluation criteria.Results: Fifty percent of the restorations were performed in premolars and 50% in molars. Local anesthesia was used in all cases except one. Resin coating was performed using HC Ⅱ alone in 40% of cases and HC Ⅱ combined with a flowable resin in 60% of cases. After inlay placement, 95% of the cases (19 cases) had a favorable outcome. Of the 10 cases (50%) where the patient experienced pain on cold water stimulation before treatment, nine cases had a favorable outcome; however, in one case pain on drinking cold water persisted and the patient then presented with pulpal symptoms, thereby requiring a pulpectomy.Conclusion: The results demonstrate the clinical efficacy of the resin-coating technique using HC Ⅱ on inlay cavity preparations.
