Abstract

Abstract: PURPOSE: To compare the effect of Nd:YAP laser and Hoshino's triple antibiotic paste on root canal disinfection in the treatment of pulp revascularization, and to provide reference for root canal disinfection in dental pulp revascularization. METHODS: Forty immature permanent teeth diagnosed as acute or chronic periapical periodontitis were included. The periapical lesions and root development were recorded. The cases were divided into 2 groups: the control group and the Nd:YAP laser disinfection experimental group. Clinical examination and X-ray evaluation of each case were performed after treatment. Statistical analysis was performed using SPSS 19.0 software package. RESULTS: Two cases showed symptoms in control group 1 week after treatment, while 4 cases had symptoms in the experimental group. The clinical symptoms disappeared in the control group 2 weeks after treatment, while 1 case still had symptoms in the experimental group. There was no significant difference between the two groups (P>0.05). Clinical evaluation at 18 months of follow-up showed that 2 and 3 cases had recurrent symptoms in the control group and the experimental group, respectively; continuous development of the root was noted in 12 and 10 cases on X-ray film in the control and experimental group, respectively, while 3 and 4 teeth had no obvious root development in the control and experimental group, respectively. There was no significant difference between the control group and the experimental group (P>0.05). CONCLUSIONS: Nd:YAP laser can be used for effective root canal disinfection without obvious effect on the prognosis of dental pulp revascularization.
