Abstract Objective To investigate and analyze the clinical efficacy of three types of subgingival irrigation as adjunctive therapies in the treatment of chronic periodontitis. Methods A total of 400 maxillary first molar of patients with chronic periodontitis in the Aviation General Hospital and Beijing Chuiyangliu Hospital from June 2016 to June 2017 were selected and divided into hydrogen peroxide group, Iodophor group, hydrogen peroxide + Iodophor group and NS group, with 100 patients in each group. After subgingival scaliing and or root planning, teeth to all the subjects, patients in hydrogen peroxide group, Iodophor group, and hydrogen peroxide + Iodophor group were irrigated by hydrogen peroxide, Iodophor, hydrogen peroxide + Iodophor, respectively, and the NS group was irrigated with 0.9% NS as the control. Once a week, for 4 weeks. Parameters including gingival index (GI), bleeding index (BI), attachment level (AL) and probing depth (PD) were compared before and after treatment. Results After treatment, GI, BI, AL and PD of patients in the four groups were significantly reduced, and the PD and AL of the hydrogen peroxide + Iodophor group were significantly lower than those of the other three groups (P < 0.05). After treatment, there was no significant difference in GI or BI among the four groups (P > 0.05). Conclusion All the three types of subgingingival irrigation can improve the curative effect to different degrees, and compared with other simple subgingival irrigating solutions, hydrogen peroxide and Iodophor achieves better clinical effectiveness.
