- Abstract: Objective To study the therapeutic effects of Er:YAG laser irradiation of different energies on early peri-implant inflammation (PI). Methods A total of 108 patients with early PI after dental implantation were enrolled. According to random number table method, they were divided into 4 groups, with 27 cases in each group. Groups A, B and C were treated by 40, 60 and 80 mJ Er: YAG laser irradiation (once a week for 3 times), respectively. Control group was treated with minocycline hydrochloride.On the 7th, 14th, 28th and 60th days after the completion of treatment, plaque index (PLI), bleeding index (BI), probing depth (PD) and bone defect depth (DD) were recorded. Before the treatment and on the 60th day after the completion of treatment, the changes in the levels of interleukin 1α (IL-1α), C-reactive protein (CRP) and tumor necrosis factor α (TNF-α) in gingival crevicular fluid (GCF) were detected. The total response rates of treatment in different groups were also compared. Results The total response rates in groups A, B and C were 88.89% (24/27), 96.30% (26/27) and 92.59% (25/27), respectively, higher than 59.26% (16/27) in control group (P<0.05). During treatment, PLI and BI were decreased, and they were improved differently in different periods among different groups (P<0.05). Compared with those in group A on the 60th day after the completion of treatment, PLI and BI in group B and group C were improved significantly (P<0.05). On the 7th day after the completion of treatment, BI in group B, group C and control group was lower than that in group A (P<0.05). The PD and DD in the 4 groups were significantly different after treatment (P<0.05). On the 14th, 28th and 60th days after the completion of treatment, PD in group B and group C was lower than that in group A and control group (P<0.05). On the 60th day after the completion of treatment, the differences in DD among different groups were statistically significant (P<0.05), and the DD in groups B and C was less than that in group A and control group (P<0.05). The levels of IL-1α, CRP and TNF-α in GCF in groups A, B and C were significantly lower than those in control group (P<0.05), and there were statistical differences among groups A, B and C (P<0.05). Conclusion Within the safe range, 60 mJ Er:YAG laser has a good therapeutic efficacy in the treatment of early PI, worthy of popularizing.
