[Therapeutic effect of chlorhexidine combined with mechanical debridement on peri-implantitis and its influence on patients' SF-36 score].

PURPOSE

To study the effect of chlorhexidine combined with mechanical debridement on peri-implant inflammation and the influence on SF-36 score of patients.

METHODS

One hundred patients with peri-implantitis admitted to Zhejiang Provincial People's Hospital from January 2015 to January 2019 were selected and randomly divided into control group and combined group with 50 cases in each group according to random number table method.Patients in both groups were treated with mechanical debridement, and patients in the combined group were gargled with chlorhexidine gargle apart from mechanical debridement. Plaque biofilm average activity and modified plaque index (mPLI), bleeding on probing (BOP), modified sulcus bleeding index (mSBI), probing the depth (PPD), clinical attachment level(AL) were measured before and after treatment. Sf-36 scale and VAS visual pain score were used to evaluate the quality of life and pain degree of patients, and the therapeutic effect and incidence of complications were assessed. The data were analyzed with SPSS 20.0 software package.

RESULTS

There was no significant difference in average activity, mPLI, mSBI, AL, PPD, BOP, VAS and SF-36 scores between the two groups before treatment(P>0.05); after treatment, the average activity, mPLI, mSBI, AL, PPD, BOP and VAS scores of plaque biofilm in the combined group were significantly lower than those of the control group, and the total effective rate of SF-36 score was significantly higher than that of the control group. The total effective rate of the combined group was significantly higher than that of the control group(P<0.05). The incidence of complications in the combined group was significantly lower than that in the control group(P<0.05).

CONCLUSIONS

Chlorhexidine combined with mechanical debridement is an effective treatment of peri-implantitis, which can effectively inhibit plaque biofilm activity and plaque formation, alleviate pain and improve the quality of life of patients.
