Analysis on Effectiveness of Joint Application of Diode Laser and Basic Periodontal Treatment on Chronic Periodontitis
Objective To observe the supportive effect of diode laser on basic periodontal treatment for the sake of providing other reliable methods for chronic periodontitis.Method Thirty patients diagnosed with chronic periodontitis at the outpatient clinic of Fuyang People's Hospital were selected and divided into two groups randomly,15 patients in each group.Four index teeth were chosen from each patient,and 6 sites were explored in each tooth,resulting in a total of 60 affected teeth and 360 sites.For the teeth in the control group,only periodontal cleaning and scraping and root planing were performed.For the teeth in the experimental group,diode laser irradiation was given on the basis of the above treatments,and the parameters of the laser treatment light were set as follow,power 1.5 W,frequency 10 Hz,and irradiation time:10 s for each tooth.Periodontal clinical indexes were compared between the two groups before the treatment 6 and 12 weeks after the treatment respectively,including the depth of probing,loss of clinical attachment and bleeding index of probing.The plaque index changes that occurred 1-5 weeks after the treatment were recorded.Furthermore,the pain level during the treatment was also recorded and compared with visual analog scale(VAS),and the effect of the two treatment modalities on the gingival soft tissue recovery time was also evaluated.Results 6 and 12 weeks after the treatment,the periodontal clinical indexes and gingival recovery time in the experimental group were much less than those in the control group(P＜0.05),and VAS scores were significantly lower in the experimental group than in the control group(P＜0.05).Both methods were effective in removing plaque.There was a difference in the plaque indexes between the two groups 1 week after the treatment(P＜0.05),but no apparent difference was presented at other time points.Conclusions Both basic periodontal treatment and auxiliary diode laser will effectively improve the periodontal clinical indicators,but the adjunctive diode laser has better clinical effect.
