Brief summary
The purpose of this study is to evaluate and compare the clinical performance of dental restorative materials in Class II cavities of primary molar teeth
Detailed description
Restorations will be placed on four primary molar teeth with proximal caries, in a split mouth design. 100 patients will be included in the study. The teeth will be randomized into four groups according to the restorative materials. Group 1: Adhesive agent+ Compomer (Dyract AP, Dentsply DeTrey, Konstanz,Germany) Group 2: Primer + Resin modified glass ionomer (Vitremer, 3M ESPE, U.S.) Group 3: Adhesive agent + Giomer (Beautifil II, (Shofu Dental, Tokyo, Japan) Group 4: Amalgam (Permite amalgam, SDI Limited, Bayswater, Australia) The restorations will be evaluated at baseline, 3., 6., 12. months for the first year, and at every 6 months for 5 years. The modified US Public Health Service criteria (secondary caries, marginal integrity, marginal discoloration and retention) will be used for clinical evaluation of restorations. The data will be analysed statistically using Wilcoxon test, chi square test and the Kaplan-Meier survival method will be used to estimate survival percentages.
Interventions
DEVICECompomer
Aesthetic resin dental materials that are used to replace structure loss, commonly for dental caries of primary tooth. Compomers designed to combine the aesthetics of traditional composite resins with the fluoride release and adhesion of glass-ionomer cements.
DEVICERMGIC
Dental restorative materials that are a combination of the desirable properties of glass-ionomer (fluoride release and chemical adhesion) with high strength and low solubility of resins.
DEVICEGiomer
Giomers are dental materials that are hybrid of compomers and glass ionomers, and are used to restore dental caries.
DEVICEAmalgam
Amalgam is a silver-colored dental restorative material that can be used to restore both primary and permanent posterior teeth which have dental caries.
