摘　　要：目的探讨激光下牙龈环切术(Circumferential supracrestal fiberotomy,CSF)辅助正畸压低对牙周炎患牙治疗效果和机制的影响。方法选取68例牙周炎患者,按照治疗方法不同分为试验组和对照组,比较两组患者的牙周指数、附着丧失、骨内根长、冠根比等指标,以及牙周组织形态和骨代谢相关因子(BMP-2、RUNX2、RANKL、OPG)的表达水平。结果试验组患者在正畸压低后,牙周指数显著降低,附着丧失显著减少,骨内根长显著增加,冠根比显著改善,牙周组织中骨形成因子显著升高,骨吸收因子显著降低,与对照组相比差异均有统计学意义。结论激光下CSF辅助正畸压低牙周炎患牙可以有效改善牙周状况和美观,增加骨内根长,减少附着丧失,其机制可能与促进牙周组织中骨形成和抑制骨吸收有关。Objective To investigate the effect and mechanism of laser-assisted circumferential supracrestal fibrotomy(Circumferential supracrestal fiberotomy,CSF)on the treatment of periodontitis teeth with orthodontic intrusion.Methods Sixtyeight patients with periodontitis who underwent orthodontic treatment in Kaifeng Stomatological Hospital from June 2020 to April 2022 were selected and divided into test group(laser-assisted CSF)and control group(no CSF)according to whether they underwent laser-assisted CSF.The periodontal index,attachment loss,intrabony root length,crown-root ratio and other indicators,as well as the morphology of periodontal tissue and the expression levels of bone metabolism-related factors(BMP-2,RUNX2,RANKL,OPG)were compared between the two groups.Results After orthodontic intrusion,the test group showed significant reduction in periodontal index,attachment loss,significant increase in intrabony root length,significant improvement in crown-root ratio,significant increase in bone formation factors and significant decrease in bone resorption factors in periodontal tissue,compared with the control group,the differences were statistically significant.Conclusion Laser-assisted CSF can effectively improve the periodontal condition and appearance of periodontitis teeth with orthodontic intrusion,increase intrabony root length,reduce attachment loss,and its mechanism may be related to promoting bone formation and inhibiting bone resorption in periodontal tissue.
