目的 应用锥形束CT分析侵袭性牙周炎(aggressive periodontitis,AgP)患者牙槽骨缺损程度和方式,探讨AgP患者牙槽骨缺损的分布规律.方法 采用简单化随机法选取中国医科大学口腔医学院牙周科门诊广泛型AgP患者40例,年龄14～ 36岁,男性15例,女性25例,采用锥形束CT对入选对象进行扫描,并应用其自带的NNT软件测量分析切牙区、尖牙区、前磨牙区及磨牙区牙齿的牙槽骨缺损程度及缺损方式.结果 40例广泛型AgP患者中,中、重度牙槽骨缺损的位点数占总位点数的86.6％(3 769/4 352).上颌磨牙区牙槽骨缺损最严重[(6.3±0.7)mm],尖牙区最轻[(4.8±0.8)mm];下颌切牙区牙槽骨缺损最严重[(5.9±0.9)mm],尖牙区最轻[(5.1±0.7)mm].上颌尖牙区、磨牙区和下颌前磨牙区同区不同位点间牙槽骨缺损程度差异有统计学意义(P＜0.05),下颌尖牙区和磨牙区同区不同位点间牙槽骨缺损程度差异有统计学意义(P＜0.01).上颌磨牙近中[(6.9±0.7)mm]和下颌切牙近中[(6.5±1.1) mm]牙槽骨缺损最严重.下颌第一磨牙近中[13.6％ (42/308)]、上颌第一磨牙近中[12.0％(39/316)]及上颌第一前磨牙近中[10.8％(34/316)]易出现斜形骨缺损.结论 广泛型AgP患者大多数位点牙槽骨缺损较严重,其中缺损最严重的部位为上颌磨牙近中和下颌切牙近中;下颌第一磨牙、上颌第一磨牙和上颌第一前磨牙近中最易出现斜形骨缺损.
目的 應用錐形束CT分析侵襲性牙週炎(aggressive periodontitis,AgP)患者牙槽骨缺損程度和方式,探討AgP患者牙槽骨缺損的分佈規律.方法 採用簡單化隨機法選取中國醫科大學口腔醫學院牙週科門診廣汎型AgP患者40例,年齡14～ 36歲,男性15例,女性25例,採用錐形束CT對入選對象進行掃描,併應用其自帶的NNT軟件測量分析切牙區、尖牙區、前磨牙區及磨牙區牙齒的牙槽骨缺損程度及缺損方式.結果 40例廣汎型AgP患者中,中、重度牙槽骨缺損的位點數佔總位點數的86.6％(3 769/4 352).上頜磨牙區牙槽骨缺損最嚴重[(6.3±0.7)mm],尖牙區最輕[(4.8±0.8)mm];下頜切牙區牙槽骨缺損最嚴重[(5.9±0.9)mm],尖牙區最輕[(5.1±0.7)mm].上頜尖牙區、磨牙區和下頜前磨牙區同區不同位點間牙槽骨缺損程度差異有統計學意義(P＜0.05),下頜尖牙區和磨牙區同區不同位點間牙槽骨缺損程度差異有統計學意義(P＜0.01).上頜磨牙近中[(6.9±0.7)mm]和下頜切牙近中[(6.5±1.1) mm]牙槽骨缺損最嚴重.下頜第一磨牙近中[13.6％ (42/308)]、上頜第一磨牙近中[12.0％(39/316)]及上頜第一前磨牙近中[10.8％(34/316)]易齣現斜形骨缺損.結論 廣汎型AgP患者大多數位點牙槽骨缺損較嚴重,其中缺損最嚴重的部位為上頜磨牙近中和下頜切牙近中;下頜第一磨牙、上頜第一磨牙和上頜第一前磨牙近中最易齣現斜形骨缺損.

Objective To evaluate the degree and pattern of alveolar bone defect in aggressive periodontitis(AgP) using cone-beam CT(CBCT),and to investigate the distribution of alveolar bone defects in aggressive periodontitis.Methods Forty AgP patients(age:14-36 years,male:15 cases,female:25 cases) were selected by simple random method and scanned by CBCT.NNT software was applied to measure the average degree of alveolar bone defects and bone loss types in different regions.Results In forty AgP patients,86.6％(3 769/4 352) sites presented moderate and severe alveolar bone defects.In the maxilla,the molar areas presented the heaviest alveolar bone defect[(6.3±0.7) mm],the canine areas showed the lightest bone loss[(4.8±0.8) mm].In the mandible,the incisal areas presented the heaviest alveolar bone defect[(5.9±0.9) mm],the canine areas showed the lightest bone loss[(5.1±0.7) mm].The degree of alveolar bone defect in the areas of maxillary canine,maxillary molars,mandibular premolar was significantly different(P＜0.05).The degree of alveolar bone defect in mandibular canine and mandibular molars was significantly differenct (P＜0.01).The most serious alveolar bone defect was in the mesial side of maxillary molar[(6.9±0.7) mm] and the mesial side of mandibular incisor[(6.5± 1.1) mm].The oblique bone defects were found in the mesial part of the first molars in mandibula[13.6％ (42/308)],the first molars in maxilla[12.0％(39/316)] and the first premolar in maxilla[10.8％(34/316)].Conclusions The alveolar bone defects of generalized AgP patients were serious.The most serious areas were located in the mesial side of maxillary molars and the mesial side of mandibular incisor.
