Filter by:The aim of this study is to determine and compare the longevity of single-tooth cast restorations made of precious metal vs. non-precious metal (e.g. partial crowns, crowns) and to determine the influence of patient-, tooth-, treatment-, and restoration-specific parameters on longevity. Patients who received single-tooth cast restorations made of precious metal or non-precious metal (e.g. partial crowns, crowns) between 1997 and 2022 will be retrospectively analyzed. Patient-, tooth-, treatment-, and restoration-specific parameters will be obtained from digital and paper-based dental records. Survival and success of the restorations will be assessed using Kaplan-Meier statistics. Mean annual failure rates (mAFR) and median survival time will be calculated (Kaplan-Meier statistics). Potential predictive factors will be tested using log-rank tests and multi-variate Cox-regression analysis.
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 the study is to evaluate the clinical performance of new bioactive injectable composite compared to nanohybrid composite during the restoration of posterior cavities
This study is conducted to evaluate the clinical performance of two fiber-reinforced resin composite restorations compared to nanohybrid resin composite restorations in patients with posterior MOD cavities
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.
In geriatric patients, will the clinical performance of nano hydroxyapatite reinforced glass ionomer be better than conventional glass ionomer cement in treatment of root caries lesions over one year follow up?
This study compares the survival rates of both direct and indirect resin-based composite restorations in the treatment of severe tooth wear.
With limited evidence-based information in literature about using self-adhering flowable composite in conservative class V restorations, it was found beneficial to evaluate the newly introduced material using a randomized controlled clinical trial to test the null hypothesis that moist bonding self-adhering flowable composite with and without adhesive system will have the same clinical performance as conventional flowable composite in cervical caries lesions.
The objective of this double-blind randomized clinical trial is to evaluate the influence of caries risk, occlusal stress and missing teeth on anterior restorations over a 10 years follow up period. 300 teeth will be randomized according to two adhesive systems: Single Bond 2 and Single Bond Universal (3M ESPE); and two composite resins: nanoparticulated (Filtek ™ Z-350- 3M ESPE) and nanohybrid (IPS Empress Direct - Ivoclar Vivadent). The randomization will be stratified according to the risk of caries and cavity type. The primary outcomes will be longevity, annual failure rate (AFR) and the success of the restorations, and the secondary outcome will be causes for restorations' failure.
