摘要
目的探讨慢性牙周炎患者牙槽骨厚度与临床指标的关系。方法选取新疆石河子市人民医院2017年12月~2019年6月收治的牙周炎患者112例为观察组,根据牙周炎严重程度分为轻度组40例,中度组38例,重度组34例。同期纳入新疆石河子市人民医院行牙周检查的牙周健康者40例为对照组。比较各组上颌中切牙根周牙周袋探诊深度(PD)、出血指数(BI)、临床附着丧失(CAL),通过锥形束CT测量上颌中切牙根周釉质牙骨质界下3、5、7 mm处腭侧、唇侧、远中、近中牙槽骨厚度。通过Spearman分析牙槽骨厚度与牙周组织破坏的关系。结果对照组、轻度、中度、重度牙周炎组患者PD、BI依次逐渐增大,比较差异有统计学意义(P<0.05),轻度、中度、重度牙周炎组患者CAL依次逐渐增大,比较差异有统计学意义(P<0.05);CEJ下3 mm处轻度牙周炎组PBT、LBT、MBT、DBT值明显低于对照组(P<0.05);CEJ下5 mm处对照组、轻度、中度牙周炎组患者PBT、LBT、MBT、DBT值逐渐降低,比较差异有统计学意义(P<0.05);CEJ下7 mm处对照组、轻度、中度、重度牙周炎组患者PBT、LBT、MBT、DBT值逐渐降低,比较差异有统计学意义(P<0.05);经Spearman分析,PD、BI、CAL均分别与PBT、LBT、MBT、DBT呈负相关(P<0.05)。结论上颌中切牙根周牙槽骨厚度与牙周组织破坏程度呈负相关,牙槽骨厚度可能与牙周炎的发生密切相关。
Objective To investigate the relationship between alveolar bone thickness and clinical index in patients with periodontitis.Methods 112 patients with periodontitis being treated in People’s hospital of Shihezi from June 2018 to June 2019 were randomly selected and divided into mild group(n=40),moderate group(n=38)and severe group(n=34)according to the severity of periodontitis.Meanwhile,other 40 healthy individuals at the same hospital were chosen as control group.The probing depth(PD),bleeding index(BI)and clinical attachment loss(CAL)were compared between four groups.Conical beam CT was used to measure the palatal bone thickness(PBL),labial bone thickness(LBL),distal bone thickness(DBL)and mesial bone thickness(MBL)respectively at 3,5,7 mm under the maxillary central incisor periodontal enamel bone junction(CEJ).The relationship between alveolar bone thickness and periodontal tissue destruction was analyzed by Spearman.Results The PD and BI had an increasing trend in control group,mild group,moderate group,and severe groups(P<0.05),and the CAL had an increasing trend in mild,moderate,and severe groups(P<0.05).At 3 mm under the CEJ,The PBT,LBT,MBT,and DBT in the mild group were significantly lower than those in the control group(P<0.05);At 5 mm under the CEJ,The PBT,LBT,MBT,and DBT had a decreasing trend in control group,mild group,and moderate groups(P<0.05).At 7 mm below the CEJ,The PBT,LBT,MBT,and DBT had an decreasing trend in control group,mild group,moderate group,and severe groups(P<0.05).Spearman analysis showed that PD,BI,and CAL were negatively correlated with PBT,LBT,MBT,and DBT,respectively(P<0.05).Conclusion Alveolar bone thickness in patients with periodontitis has a negative correlation with the degree of periodontal tissue destruction.Alveolar bone thickness may play a role in the occurrence and development of periodontitis.
