摘要
目的探讨重度牙周炎患者的磨牙对应上颌窦黏膜厚度的变化。方法选取2017年2月~2019年2月我院口腔科收治的行上颌磨牙拔除治疗的重度牙周炎患者作为研究组(14例),另外选取同期口腔科收治的上颌磨牙存在牙槽骨轻度吸收的患者作为对照组(15例)。两组均进行锥形束CT(CBCT)检查,测量比较两组磨牙对应上颌窦黏膜的厚度最大值(maxMT)及磨牙剩余牙槽骨高度最小值(minRRH),统计其黏膜增厚比例。并对研究组患者在拔除上颌磨牙、位点保存术6个月后对应的上颌窦黏膜厚度的变化情况进行分析。结果研究组治疗前的磨牙maxMT高于对照组,上颌窦黏膜增厚的比例高于对照组,差异有统计学意义(P<0.05);研究组治疗前的minRRH低于对照组,差异有统计学意义(P<0.05)。研究组磨牙拔除后对应上颌maxMT低于治疗前,上颌窦黏膜增厚的比例低于治疗前,差异均有统计学意义(P<0.05)。结论重度牙周炎患者的磨牙对应上颌窦黏膜的厚度明显增加,经上颌磨牙拔除同期拔牙位点保存术治疗后,其病理性增厚明显改善。
Objective To investigate the changes of maxillary sinus mucosa thickness corresponding to molars in patients with severe periodontitis.Methods From February 2017 to February 2019,patients with severe periodontitis treated by maxillary molar extraction were selected as the study group(n=14),and patients with mild alveolar bone resorption in maxillary molars treated in the department of stomatology at the same time were selected as the control group(n=15).The patients in both groups were examined by conical bundle CT(CBCT),the maximum thickness of maxillary sinus mucosa(maxMT)and the minimum alveolar bone height(minRRH)of molars were measured and compared between the two groups.And the proportion of mucosal thickening was counted.After 6 months of extraction of maxillary molar and site preservation,the changes of mucosal thickness of maxillary sinus in the study group were analyzed.Results The thickness of maxMT before treatment in the study group was higher than that in the control group,the proportion of mucosal thickening in the maxillary sinus was higher than that in the control group,the differences were statistically significant(P<0.05);the minRRH before treatment in the study group was lower than that in the control group,the difference was statistically significant(P<0.05).After molars extraction in the study group,the corresponding maxMT was significantly lower than before treatment,and the proportion of maxillary sinus mucosal thickening was lower than before treatment,the differences were statistically significant(P<0.05).Conclusion The thickness of molars corresponding to maxillary sinus mucosa in patients with severe periodontitis is significantly increased,and the pathological thickening is significantly improved after simultaneous extraction site preservation.
