View clinical trials related to Dental Restoration Failure.
Filter by:Despite significant advances in composite materials, they are still perceived as technique-sensitive and exhibit failure related to excessive wear and polymerization shrinkage. Cention N is a recently introduced alkasite restorative that contains special reactive fillers. Its application in restorative dentistry may be significant, promoting remineralization of carious lesions & reduction of polymerization shrinkage. The study will aim to compare the clinical performance of Cention N (with and without adhesive) and composite resin (Filtek Bulk Fill) in class I restorations using FDI criteria. Thirty-six class I cavities will be selected and equally allocated into 3 groups: Group I (n=12): (Cention N with adhesive), Group II (n=12): (Cention N without adhesive) & Group III (n=12): composite resin (Filtek Bulk Fill) in class I cavities. Patients will be followed up at 1 week 3, 6, and 12 months and evaluated using the FDI criteria. Postoperative sensitivity, staining, and recurrent caries will be evaluated in this clinical trial.
Clinical performance of two different ceramic restoration in patient mouth after 3 years follow up
The aim of this study will be to evaluate the clinical performance of polyethylene fiber reinforced resin composite restorations versus bulk fill resin composite restorations in endodontically treated teeth.
This study compares the survival rates of both direct and indirect resin-based composite restorations in the treatment of severe tooth wear.
The purpose of this study is to determine whether a new tooth-colored composite material is effective for load-bearing dental fillings.
A cohort of 20 patients aged 18 to 80 years (mean 28.35 years) of both genres females (65%) and males (35%) with 80 composite restorations were recruited at the Operative Dentistry Clinic at the Dental School of the University of Chile. All participants presented with marginal adaptation clinical features that deviated from the ideal and were rated Bravo according to the modified United States Public Health Service (USPHS) criteria for the sealing group and no treatment group. As a positive control were considered composites with alpha values in marginal adaptation. The protocol was approved by the Institutional Research Ethics Committee of the Dental School at the University of Chile (Project PRI-ODO-0207). All of the patients signed informed-consent forms and completed registration form. The selection criteria are summarized below.
