Abstract
Objective To explore the influence of Z350 nanocomposite fluid resin on the repair effect and pulp reaction status in patients with dental wedge-shaped defects.Methods A retrospective analysis was performed on the clinical data of patients with dental wedge-shaped defects in the department of stomatology of Lixin County Hospital of Traditional Chinese Medicine,Bozhou City,Anhui Province from March 2022 to March 2023.35 patients(43 affected teeth)with Z350 nanocomposite fluid resin were included in observation group,and 31 patients(37 affected teeth)with resin-modified light-cured glass ionomer material were enrolled as control group.The repair effect and occurrence of complications(tooth soreness,pulpitis,discoloration)at 3 months after treatment and relevant periodontal biomarkers[(Alkaline phosphatase,ALP),(aspartate aminotransferase,AST),(Gingival crevicular fluid,GCF)],pulp reaction status(pulp electrical activity,pulp stimulation degree),masticatory function(masticatory efficiency,occlusal force)and dental aesthetics[(Index of orthodontic treatment need-aesthetic component,IOTN-AC)]before treatment and at 3 months after treatment were compared between both groups of patients.Results The effective rate of repair in observation group was significantly higher than that in control group(P＜0.05),and the total incidence rate of complications was significantly lower compared to control group(P＜0.05).At 3 months after treatment,the levels of ALP,AST and GCF in both groups were significantly enhanced than those before treatment,but the observation group had lower levels(all P＜0.05).The pulp electrical activity,pulp stimulation degree and IOTN-AC scores were significantly reduced compared with those before treatment,and the above indicators were lower in observation group(all P＜0.05).The masticatory efficiency and occlusal force at 3 months after treatment were obviously risen than those before treatment(P＜0.05),but there were no statistical difference between the two groups(P＞0.05).Conclusion Z350 nanocomposite fluid resin can effectively repair the dental wedge-shaped defects,and significantly improve the relevant periodontal biomarkers,pulp reaction status,masticatory function and dental aesthetics of patients.关键词
