牙周病的单纯性牙周治疗和牙周正畸联合治疗的疗效比较

目的 探讨牙周病的单纯性牙周治疗和牙周正畸联合治疗的疗效。 方法 选择2011年1月—2014年1月在浙江省丽水市人民医院口腔科诊断为牙周病的患者38例作为研究对象，38例患者先进行单纯性牙周治疗，牙周状况进入静止期后给予牙周正畸联合治疗。比较单纯性牙周治疗前后及牙周正畸联合治疗前后测量探诊深度、牙冠长度、牙根长度和牙槽骨密度。 结果 单纯性牙周治疗后的探诊深度明显低于治疗前(P＜0.05)，牙周正畸联合治疗后的探诊深度明显低于治疗前(P＜0.05)。单纯性牙周治疗后的牙冠长度明显高于治疗前(P＜0.05)，牙周正畸联合治疗后的牙冠长度明显高于治疗前(P＜0.05)。单纯性牙周治疗组治疗后的牙根长度和治疗前比较差异无统计学意义(P＞0.05)，牙周正畸联合治疗组治疗后的牙根长度和治疗前比较差异无统计学意义(P＞0.05)。单纯性牙周治疗组治疗后的牙槽嵴顶骨密度明显高于治疗前(P＜0.05)，牙周正畸联合治疗组治疗后的牙槽嵴顶骨密度明显低于治疗前(P＜0.05)。单纯性牙周治疗组治疗后的根尖区骨密度明显高于治疗前(P＜0.05)，牙周正畸联合治疗组治疗后的根尖区骨密度明显低于治疗前(P＜0.05)。 结论 牙周病单纯性牙周治疗和牙周正畸联合治疗均可以改善牙周情况，增加牙冠长度，不增加牙根长度，单纯性牙周治疗增加牙槽骨的骨密度，牙周正畸联合治疗减少牙槽骨的骨密度。 

Efficacy of simple periodontal treatment and combined periodontal and orthodontic treatment on periodontal disease

Objective Tocompared the efficacy of simple periodontal treatment and periodontal orthodontic in the treatment of periodontal disease. Methods Total 38 cases of periodontal disease patients in our hospital were selected as research subjects,38 patients were first treated with simple periodontal treatment,after the periodontal status entering the stationary phase,thecombined periodontal and orthodontic treatment was performed.The measurement probing depth,crownlength,root length and alveolar bone density were compared before and after simple periodontal treatment and before and after the periodontal orthodontic treatment. Results The probing depthafter simple periodontal treatment was significantly lower than before the treatment(P<0.05),the periodontal probing depth after the periodontal orthodontic treatment was significantly lower than before treatment (P<0.05).The crown length aftersimple periodontal treatment was significantly higher than before(P<0.05),the crown length after periodontal orthodontic treatment was significantly higher than before(P<0.05).The root length of after simple periodontal treatment was no difference than before(P>0.05),the root length after periodontal orthodontic treatment was no difference than before(P>0.05).The alveolarcrestal bone mineral density aftersimple periodontal treatment was significantly higher than before(P<0.05),the crestal bone mineral density after periodontal orthodontic treatment was significantly higher than before(P<0.05).The apical bone mineral density aftersimple periodontal treatment was significantly higher than before(P<0.05),the apical bone mineral density after periodontal orthodontic treatment was significantly higher than before(P<0.05). Conclusion The simple periodontal treatment and periodontal orthodontic treatment for periodontal disease can all improve periodontal condition,increase crown length without increase root length.The simple periodontal treatment can increase the alveolar bone density,but the periodontal orthodontic treatment will reduce alveolar bone density.
