Abstract
Objective To investigate the effect of nano-composite resin on cosmetic repair of maxillary anterior teeth.Methods From June 2021 to June 2023,patients who underwent cosmetic repair of maxillary anterior teeth in the Affiliated Stomatological Hospital of Nanjing University Medical College were selected as the research objects.They were divided into two groups according to the random number table method,59 cases in each group.The control group was repaired with light-cured composite resin,and the observation group was repaired with nano-composite resin.The two groups were followed up for 3 months after repair,and the clinical efficacy of the patients was evaluated at 3 months after repair.The pain level[visual analogue scale(VAS)]and postoperative sensitivity at different time points(1 month,2 months and 3 months after repair)were recorded and compared.Clinical score(Ryge),pink aesthetic index(PES)score,periodontal related indexes[gingival index(GI),plaque index(PLI),sulcus bleeding index(SBI),tooth mobility(MD)]were measured before and 3 months after restoration.The prosthesis loosening,prosthesis shedding were recorded and compared between the two groups during the follow-up period.Results After repair,the proportion of A-grade repair patients in the observation group was higher than that in the control group in terms of edge fit,color matching(P＜0.05).After 3 months of repair,the VAS scores of both groups were lower than those of 1 and 2 months after repair,and the observation group was lower than the control group.There were statistically significant differences between the two groups in terms of time points,between groups,and interaction comparison(P＜0.05).After repair,the Ryge scores of both groups were lower than before repair,and the Ryge score of the observation group was lower than that of the control group,The PES score was higher than before repair,and the PES score was higher than the control group(P＜0.05).At 1,2,and 3 months after restoration,the incidence of tooth sensitivity in the observation group was lower than that in the control group(P＜0.05).The stability of the restoration in the observation group was higher than that in the control group(P＜0.05).After restoration,the periodontal related indicators in both groups were lower than before restoration,and the observation group was lower than the control group(P＜0.05).Conclusion Nanocomposite resin can effectively improve the clinical efficacy of patients with cosmetic repair of maxillary anterior teeth,reduce the incidence of postoperative sensitivity,improve the aesthetics of teeth,improve the stability of repair.关键词
