目的探讨Beyond冷光美白技术对活髓变色牙齿进行漂白时敏感发生情况。方法于2009年6月至2010年3月在解放军第463医院口腔门诊用Beyond冷光美白仪及配套的冷光美白剂对30例患者的活髓变色牙齿进行漂白,其中10例患者术前曾服用止痛剂,分别观察术中、术后24、72h及1周患者牙齿敏感情况。结果术前服用止痛剂者均未出现敏感症状;未服用者术中有14例(70.0%)患者有程度不等的牙齿敏感症状,其中2例(14.3%)患者出现牙髓刺激症状,术后24h17例(85.0%)患者有不同程度牙齿敏感症状,术后72h至1周可自动消除,未见有牙髓炎症状发生。结论 Beyond冷光美白技术对牙髓的刺激性为可复性、短时性、一过性。术前如进行完善彻底检查,给予口服止痛剂,术中规范操作将有助于减少敏感疼痛发生。
Objective To investigate the sensitivity of Beyond cold-light whitening technique to the bleaching of live pulp discolored teeth. Methods From March 2009 to March 2010, bleomyctomy of live pulp discoloration of 30 patients was performed in the 46th Hospital of People’s Liberation Army Oral Clinic with Beyond cold light whitening instrument and matched cold light whitening agent. Ten patients took pain relief preoperatively Agents were observed intraoperative and postoperative 24,72 h and 1 week patients with dental sensitivity. Results There were no sensitivities in patients taking analgesics before operation. Tooth sensitivities were found in 14 patients (70.0%) who were not taking intraoperatively, and 2 patients (14.3%) had endodontic symptoms After 24h, 17 cases (85.0%) patients had different degree of tooth sensitivity symptoms, and could be eliminated automatically after 72 hours to 1 week. No symptoms of pulpitis occurred. Conclusion Beyond cold light whitening technology on the pulp irritation is refolding, short-term, transient. Perfection as a thorough preoperative examination, given oral analgesics, intraoperative standard operation will help reduce the incidence of sensitive pain.
