[Effect of dual-wavelength laser combined with bioceramics iRoot SP to assist molar root canal treatment].

Purpose: To investigate the effect of dual-wavelength laser combined with bioceramics material iRoot SP on molar root canal treatment.

Methods: A total of 104 patients receiving root canal treatment from January 2020 to June 2023 were selected and divided into control group and experimental group according to random number table method, with 52 cases in each group. The control group was treated with iRoot SP paste, and the experimental group was treated with dual-wavelength laser(Nd:YAG and Er:YAG) combined with iRoot SP paste. The total effective rate, pain degree and complications were compared. Serum interleukin-6 (IL-6), interleukin-17(IL-17), tumor necrosis factor-α(TNF-α), bleeding index(BI), depth of periodontal probing(PD) and clinical attachment level(CAL) were observed before treatment, 6 weeks and 12 weeks after treatment. SPSS 22.0 software package was used for statistical analysis.

Results: The total effective rate of the experimental group was significantly higher than that of the control group, and the pain degree after root canal filling was significantly lower than the control group(P＜0.05). The levels of IL-6, IL-17, TNF-α, BI, PD and CAL in the experimental group were significantly lower than those in the control group at 6 and 12 weeks after treatment (P＜0.05).

Conclusions: Dual wavelength laser combined with bioceramic material iRoot SP has a better effect in the treatment of molar root canal, which is conducive to reducing periodontal inflammation and pain.
