Effects of dental pulp revascularization in treatment of young permanent teeth with pulp necrosis and periapical periodontitis
Objective:To observe effects of dental pulp revascularization in treatment of young permanent teeth with pulp necrosis and periapical periodontitis. Methods:A prospective study was conducted on 68 children with pulp necrosis and periapical periodontitis of young permanent teeth admitted to this hospital from February 2021 to January 2024. According to the random number table method,they were divided into observation group and control group,34 cases in each group. The control group was treated with conventional apexification,while the observation group was treated with dental pulp revascularization. The clinical efficacy,the root index (root length,root canal wall thickness) levels and the pain[visual analogue scale (VAS)]score before and after the treatment,and the incidence of complications were compared between the two groups. Results:he total effective rate of the observation group was 97.06% (33/34),which was higher than 73.53% (25/34) of the control group,and the difference was statistically significant (P<0.05). After the treatment,the levels of root canal wall thickness and root length of the two groups were greater than those before the treatment,those of the observation group were greater than those in the control group,and the differences were statistically significant (P<0.05). After the treatment,the VAS scores of the two groups were lower than those before the treatment,that in the observation group was lower than that in the control group,and the differences were statistically significant (P<0.05). Further,the incidence of complications in the observation group was 5.88% (2/34),which was lower than 23.53% (8/34) in the control group,and the difference was statistically significant (P<0.05). Conclusions:Dental pulp revascularization in the treatment of pulp necrosis and periapical periodontitis in young permanent teeth can improve the total effective rate of treatment,improve the levels of root indexes,and reduce the pain scores and the incidence of complications. Moreover,it is superior to conventional apexification.
