Abstract

Abstract:

Objective To explore and compare the clinical effects of Er: YAG laser combined with Nd: YAG laser assisted non-surgical treatment of smoking and non-smoking patients with Stage Ⅲ Grade C periodontitis. Methods A total of 52 patients with Stage Ⅲ Grade C periodontitis who visited the Periodontology Department of Linyi People’s Hospital from March 2023 to May 2024 were selected. A total of 208 teeth were collected. The subjects were divided into four groups: smoker control group (SP group), smoker experimental group (ST group), non-smoker control group (NSP group), non-smoker experimental group (NST group). The control groups were treated with subgingival scaling and root planing, while the experimental groups were treated with Er: YAG laser combined with Nd: YAG laser assisted therapy on the basis of subgingival scaling and root planing. The plaque index (PLI), gingival index (GI), probing depth (PD) and attachment loss (AL) were recorded at baseline, 1 month, and 6 months after treatment. Three hours after treatment, each patient used the visual analogue scale (VAS) to assess the level of discomfort experienced during the treatments. Results After 1 and 6 months of treatment, all periodontal indices were significantly reduced compared to those before treatment (P<0.05). There were no significant differences in PLI, GI changes among the groups (P>0.05). The PD and AL in the ST group and NST group were significantly lower than those in the SP group and NSP group, respectively (P<0.05), and the PD and AL in the NSP group and NST group were significantly lower than those in the SP group and ST group, respectively (P<0.05). After 3 h of treatment, there was no significant difference in VAS scores among the groups (P>0.05). Conclusion Erbium-neodymium dual-wavelength laser can serve as an adjunctive method for the basic treatment of smoking-related periodontitis patients, potentially facilitating the healing response in those patients after non-surgical treatment.
