Résumé
Objective:To explore the clinical efficacies of root canal filling and repair material(iRoot BP plus)and trioxide condensate(MTA)of root canal repair material,which were used in endodontic revascularization of dental pulp,in treating the apical infection of young permanent teeth.Methods:A total of 40 young patients with apical infection of permanent teeth admitted to the dental department of hospital were selected,and they were divided into an observation group and a control group according to the random number table method,with 20 cases in each group.All patients adopted endodontic revascularization of dental pulp to conduct treatment.The observation group used iRoot BP plus to seal the upper end of the root canal,and the control group used MTA to seal the upper end of the root canal.The clinical efficacy,treatment cycle,frequency of visits,recovery time of chewing and recovery time of apical infection of the two groups of patients were compared.At the same time,the thickness of root canal wall and the root length,as well as the satisfaction of patients for treatment,of the two groups were compared.Results:After endodontic revascularization of dental pulp,the total effective rate of treatment in the observation group was 95%,which was significantly higher than 60%in the control group,and the difference was statistically significant(x2=8.326,P>0.05).Compared with the control group,the treatment cycle,frequency of visits,recovery time of chewing and recovery time of apical infection of the observation group were significantly shortened,and the differences were statistically significant(t=12.492,t=10.424,t=6.524,t=11.907,P<0.05),respectively.After treatment,the length of the root of dental crown and the thickness of root canal wall of the patients in the observation group were respectively longer and better than those in the control group,the differences were statistically significant(t=8.742,t=7.048,P<0.05).The four satisfaction scores of patients in the observation group,which included bite,tooth color,chewing ability and overall aesthetics,were respectively higher than those in the control group,and the differences were statistically significant(t=5.437,t=5.093,t=7.591,t=6.852,P<0.05).Conclusion:iRoot BP plus has more advantages than MTA when the endodontic revascularization of dental pulp is used to treat the apical infection of young permanent teeth,which can more effectively improve the clinical efficacy and treatment satisfaction of patients.
