Effect of Nd︰YAG Laser Assisted in Treating Periodontitis on Bone Metabolism and Periodontal Esthetics of Patients
Objective To explore the effects of Nd∶YAG laser assisted in treating periodontitis on bone metabolism and periodontal esthetics of patients.Methods Sixty patients with periodontitis admitted to the author's hospital from January 2017 to April 2020 were selected and divided into control group and observation group by random number table method,with 30 patients in each group.The control group was treated with ultrasonic subgingival scaling and root surface leveling,and the observation group was treated with Nd∶YAG laser on the basis of the control group,the therapeutic effect was observed 3 months after treatment.The total effective rate of the two groups at 3 months after treatment was compared,levels of periodontal indexs,gingival crevicular fluid osteocalcin(OCN),type i collagen(COL-I),nuclear factor κB receptor activating factor ligand(RANKL)and inflammatory factors before treatment and at 3 months after treatment of the two groups were compared.Results At 3 months after treatment,the total effective rate of the observation group was 96.67%,higher than that of the control group(76.67%)(P<0.05).At 3 months after treatment,plaque Index(PLI),gingival Index(GI)scores,pocket depth(PD)level,RANKL、tumor necrosis factor-α(TNF-α),interleukin 6(IL-6),interleukin 1β(IL-1β)levels of gingival crevicular fluid in both groups were lower than those before treatment,and those in the observation group were lower than those in the control group(P<0.05).At 3 months after treatment,OCN,CoL-I levels of gingival crevicular fluid in the two groups were higher than those before treatment,and those in the observation group were higher than those in the control group(P<0.05).Conclusion Nd∶YAG laser assisted in treating periodontitis could improve OCN and COL-I levels of gingival crevicular fluid,reduce RANKL level of gingival crevicular fluid,improve bone metabolism,inhibit inflammatory response,and then improve periodontal aesthetics esthetics indexs,with effective effect.
