目的 应用锥形束 CT 观测并分析慢性牙周炎患者牙槽骨缺损的形态特点,探讨慢性牙周炎牙槽骨缺损的分布规律.方法 采用单纯随机抽样法选取慢性牙周炎患者60例,对入选对象进行锥形束CT扫描并应用锥形束CT自带的NNT软件测量切牙区、尖牙区、前磨牙区及磨牙区牙齿(近中、远中、颊侧、舌侧4个位点)的平均牙槽骨缺损程度及缺损形式.结果 75％(45/60)的慢性牙周炎患者牙槽骨缺损形式为广泛型,25％ (15/60)的患者牙槽骨缺损形式为局限型；切牙区及尖牙区的下颌牙槽骨缺损程度均高于上颌相同位点；前磨牙区的下颌牙槽骨缺损程度低于上颌相同位点；下颌磨牙区的近中、远中及颊侧的牙槽骨缺损程度较上颌区域重,腭侧牙槽骨缺损程度低于上颌.结论 慢性牙周炎患者牙槽骨缺损较重的部位位于上颌磨牙的腭侧及下颌切牙的舌侧,锥形束CT扫描有利于更好地了解慢性牙周炎牙槽骨缺损的形式,对慢性牙周炎的治疗和预后评估具有一定的临床指导意义.
目的 應用錐形束 CT 觀測併分析慢性牙週炎患者牙槽骨缺損的形態特點,探討慢性牙週炎牙槽骨缺損的分佈規律.方法 採用單純隨機抽樣法選取慢性牙週炎患者60例,對入選對象進行錐形束CT掃描併應用錐形束CT自帶的NNT軟件測量切牙區、尖牙區、前磨牙區及磨牙區牙齒(近中、遠中、頰側、舌側4箇位點)的平均牙槽骨缺損程度及缺損形式.結果 75％(45/60)的慢性牙週炎患者牙槽骨缺損形式為廣汎型,25％ (15/60)的患者牙槽骨缺損形式為跼限型；切牙區及尖牙區的下頜牙槽骨缺損程度均高于上頜相同位點；前磨牙區的下頜牙槽骨缺損程度低于上頜相同位點；下頜磨牙區的近中、遠中及頰側的牙槽骨缺損程度較上頜區域重,腭側牙槽骨缺損程度低于上頜.結論 慢性牙週炎患者牙槽骨缺損較重的部位位于上頜磨牙的腭側及下頜切牙的舌側,錐形束CT掃描有利于更好地瞭解慢性牙週炎牙槽骨缺損的形式,對慢性牙週炎的治療和預後評估具有一定的臨床指導意義.

Objective To evaluate the morphological characteristics of alveolar bone defects of the patients with chronic periodontitis using cone-beam CT (CBCT).Methods Sixty patients with chronic periodontitis were included in this study.CBCT was used to scan the alveolar bone and NNT software to measure the alveolar bone defects and bone loss types in different regions.Results Seventy-five percent (45/60) of the alveolar bone defect was the generalized type,25％ (15/60) was the localized type.In incisor and canine area,the defect of the mandibular alveolar bone was more severe than in the same sites of maxilla.There was less bone loss in the premolar area of mandible than in the same site of maxilla.In the mesial and buccal sites of mandibular molars and in the lingual site of maxillary molars,the most severe alveolar bone loss was found.Conclusions The obvious alveolar bone defect areas in chronic periodontitis were the palatal side of maxillary molars and the lingual side of mandibular incisors.CBCT can clearly demenstrate the degree of alveolar bone defects in different regions of chronic periodontitis.
