Evaluation of a new resin-based composite material.
Amalgam and composite are the most commonly used restorative materials in dentistry. Due to the toxicity of mercury and the subsequent environmental problems, the search for alternatives continues and search into new composite restorative materials intensifies. The presently available composites have improved, but shrinkage of the composite during the curing procedure is still a clinical problem. A new composite restorative material has among other advantages demonstrated lower shrinkage in laboratory studies, due to a new formulation of the material.
This project aims to study the clinical performance of this new composite compared to a commonly used composite restoration material. 72 patients (158 teeth) are allocated to the project which is carried out at the School of dentistry, University of Aarhus, Denmark.
This project aims to study the clinical performance of a new composite restoration material (Filtek Silorane®) compared to a conventional composite restoration material (Ceram X®).
Amalgam and composite are the most commonly used restorative materials, with the number of composite restorations increasing over the past 20 years. Composite restorative materials have improved considerably over the years. They have almost reached the same resistance to wear as amalgam, and are as a consequence now also used for molar restorations.
The main reasons for replacing composite restorations are fractures and caries associated with the restorations.
To reduce the risk of caries a new composite material Filtek Silorane® with reduced polymerization shrinkage has been developed.
Extensive laboratory studies have been performed on the new material, but the clinical attributes have yet to be disclosed.
The study will be carried out as a randomized, double blinded, longitudinal study, with assessment of the restorations after one year.
The project includes 72 patients, 158 teeth. Most of the patients have been recruited from the Treatment Planning Clinic at the dental school in Aarhus. After giving their consent to take part in the study, the teeth are randomized into two treatment groups. Multi surface restorations of both upper and lower molars and premolars are performed
The treatment procedure is:
The patients are offered local anesthetic before treatment start. The cavity is excavated and filled according to the guidelines for composite restorations. An impression of the cavity is taken before and after it has been filled. After treatment bw-radiographs are taken.
The control procedure is:
The restoration is evaluated according to marginal adaptation, cavo surface marginal discoloration, approximal contact, fractures, caries associated with restorations and postoperative hypersensitivity. The controls will take place after three weeks and one year.

Restorations of metal, porcelain, or plastic made to fit a cavity preparation, then cemented into the tooth. Onlays are restorations which fit into cavity preparations and overlay the occlusal surface of a tooth or teeth. Onlays are retained by frictional or mechanical factors.
Dental caries involving the tooth root, cementum, or cervical area of the tooth.
A tooth's loss of minerals, such as calcium in hydroxyapatite from the tooth matrix, caused by acidic exposure. An example of the occurrence of demineralization is in the formation of dental caries.
The predisposition to tooth decay (DENTAL CARIES).
Treatment for the prevention of periodontal diseases or other dental diseases by the cleaning of the teeth in the dental office using the procedures of DENTAL SCALING and DENTAL POLISHING. The treatment may include plaque detection, removal of supra- and subgingival plaque and calculus, application of caries-preventing agents, checking of restorations and prostheses and correcting overhanging margins and proximal contours of restorations, and checking for signs of food impaction.
