摘要
目的观察在口腔手术显微镜下使用无机三氧化物聚合体(MTA)修复髓腔穿孔的临床疗效。方法对37例19～57岁因髓腔穿孔的患者,在口腔显微镜下使用MTA进行穿孔区修复治疗。术后随访进行临床评价,包括MTA修复后的临床症状、牙齿松动度、髓腔穿孔区周围牙槽骨是否发生吸收情况。结果术后1周复诊,所有患者临床症状均无不适,12个月复诊,37例患牙穿孔区牙槽骨均未继续发生骨吸收。结论口腔手术显微镜下MTA在用于髓腔穿孔修复时定位准确,能够较好地封闭穿孔,促使牙槽骨病变恢复。
Objective To observe the effect of mineral trioxide aggregate（MTA） in repairing pulp cavity perforation by using oral surgical microscope.Methods A total of 37 patients of 19~57 years old with pulp cavity perforation were studied.MTA was used for repairing perforation area treatment.Regular follow-up clinical evaluation included clinical symptoms,the degree of tooth looseness,and alveolar bone absorption around perforation area.Results In the observation after 12 months,all cases exhibited normal chewing function without any complaint.In X-ray film,the areas of previous alveolar bone lesion decreased.Conclusion MTA used in pulp cavity perforation restoration has accurate positioning,better able to close perforation,and prompt alveolar recovery.MTA may be one kind of ideal biomaterials for repairing perforation in dental cavity.
