Analyze the clinical effect of YAG laser combined with sodium hypochlorite in root canal treatment of pulpitis

Abstract

Objective: To compare and analyze the clinical therapeutic effects of sodium hypochlorite combined with Nd: YAG laser and sodium hypochlorite alone for root canal disinfection in patients with pulpitis. Methods: Patients with pulpitis were divided into control group and observation group according to random number table method. Both groups received root canal treatment, while the control group received root canal irrigation with 1% sodium hypochlorite. The observation group was irrigated with 1% sodium hypochlorite combined with Nd: YAG laser. Periodontal index, inflammatory index, life quality score and bacterial infection clearance rate of the two groups were compared before and 3 months after treatment. Results: The total effective rate of the observation group was 95.35%, which was higher than that of the control group 79.07% (p
