全身疾病对拔除老年人下颌第三磨牙的影响

The effect of whole body disease on mandibular third molar extraction in the elderly

目的:对老年人下颌第三磨牙就诊情况进行归纳总结,分析全身疾患对下颌第三磨牙治疗的影响情况。方法:随机选择502例老年人下颌第三磨牙534例,分析患者牙齿情况和全身情况,依靠相关科室协助实施手术;设立对照组:60岁以下排除全身及局部疾患的拔除下颌第三磨牙的健康患者150例,一并统计术后并发症情况。结果:502例患者均得到相对安全有效的治疗,观察组与对照组在术后并发症比较显示仅在干槽症的发生率上有统计学差异(P<0.05)。结论:在诊治老年人下颌第三磨牙时,只要认真分析患者全身及局部情况,可以有效降低手术风险,但术后应注意预防感染。

Objective： To summarize and analyze clinical characteristics of treatment of mandibular third molar in elderly patients and influence of systematic diseases on mandibular third molar extraction. Methods： 502 elderly patients with 534 mandibular third molars were randomly selected, and the general and local health was examined. 150 cases of mandibular third molar extraction of healthy patients under 60 years old without systemic diseases were included as control group.Postoperative complication was evaluated. Results： No complaint of surgical injury was reported. All elderly patients received effective and safe treatment. Significant difference of the postoperative complications between the two groups was found only in the incidence of dry socket（P〈0.05）. Conclusion： To substantially reduce surgical risks, it is important to analyze the systemic and local condition of elderly patients before extraction and to pay attention to anti-infective therapy.
