This study evaluates the frequency of osteoradionecrosis associated with dental extractions.
A total of 405 patients submitted to radiotherapy and had dental extractions were evaluated. The patients were divided into 3 groups.
In group 1, 316 patients were submitted to 1.647 dental extractions (mean 5.2 teeth per patient) and in another 47 patients the number of teeth removed was not clearly reported. Group 2 comprised 5 patients who had 33 teeth extracted (mean 6.6 each). In group 3, 55 patients had 290 teeth removed (mean 5.3 each) and in another 2 patients the number of dental extractions could not be established. In general, only 3 cases of osteoradionecrosis related to dental extractions were observed: 2 related to exodontias performed before and 1 after radiotherapy.
The low prevalence of osteoradionecrosis found in this work suggests the possibility of performing exodontias after radiotherapy by experienced dentists in the management of head and neck cancer.
本研究评估与拔牙相关的放射性骨坏死的发生率。
共评估了405例接受放疗并拔牙的患者。这些患者被分为3组。
第1组，316例患者接受了1647次拔牙（平均每位患者5.2颗牙），另有47例患者拔除牙齿的数量未明确报告。第2组包括5例患者，共拔除33颗牙（平均每位患者6.6颗）。第3组，55例患者拔除290颗牙（平均每位患者5.3颗），另有2例患者的拔牙数量无法确定。总体而言，仅观察到3例与拔牙相关的放射性骨坏死病例：2例与放疗前拔牙有关，1例与放疗后拔牙有关。
本研究中发现的放射性骨坏死低发生率表明，在头颈部癌症的治疗中，经验丰富的牙医在放疗后进行拔牙是有可能的。
