The effects of combined Nd∶YAG and Er∶YAG laser therapy in the treatment of chronic periodontitis patients with Type 2 diabetes mellitus
30 patients with chronic periodontitis and Type 2 diabetes mellituse were included.By a split-mouth design,the teeth in the left side were served as the experiment group and given Nd∶YAG and Er∶YAG laser therapy adjunctive to conventional periodontal treatment;the teeth in the right side were served as the control group and given conventional periodontal treatment alone.Before and after treatment perio-dontal and CBCT image indexes were examinde and compare between the 2 groups.Before treatment all the indexes were not statistically dif-ferent between the 2 groups(P＞0.05).3 months after treatment,the bleeding index(BI)and probing depth(PD)of the experimental group were significantly lower than those of the control group(P＜0.05).6 months after treatment,BI,PD and attachment loss(AL)in the experi-mental group were significantly lower than those in the control group,and the surface area and volume of the root in the alveolar bone were significantly higher than those in the control group(P＜0.05).Nd∶YAG and Er∶YAG laser therapy adjunctive to conventional periodontal treatment is more effective than conventional periodontal treatment alone in the treatment of chronic periodontitis with type 2 diabetes melli-tus.
