12-year survival of composite vs. amalgam restorations.

Contains fulltext : 89725.pdf (publisher's version ) (Closed access)Information about the long-term clinical survival of large amalgam and composite restorations is still lacking. This retrospective study compares the longevity of three- and four-/five-surface amalgam and composite restorations relative to patients' caries risk. Patient records from a general practice were used for data collection. We evaluated 1949 large class II restorations (1202 amalgam/747 composite). Dates of placement, replacement, and failure were recorded, and caries risk of patients was assessed. Survival was calculated from Kaplan-Meier statistics. After 12 years, 293 amalgam and 114 composite restorations had failed. Large composite restorations showed a higher survival in the combined population and in the low-risk group. For three-surface restorations in high-risk patients, amalgam showed better survival.1 oktober 201

Literature review: Restorations of class II cavities in the primary dentition with compomers

A large number of studies concerning the use of compomers in class II cavities in the primary dentition already exist, but the variety of the research perspectives is even bigger. AIM: This study therefore intends to abridge and evaluate the existing research through a systematic literature review. METHODS: In order to gather relevant articles an extended literature research was carried out. The criteria for the evaluation of the resulting articles were based on the article of Kilpatrick and Neumann [2007]. RESULTS: According to the subject of the research, the articles were divided into the following groups: PAM-C; PAM-C and amalgam; PAM-C and GIC; PAM-C and hybrid composites; PAM-C and pre-treatment. CONCLUSIONS: The findings lead to the conclusion that PAM-C can be an alternative to other restorative materials in the primary dentition in class II cavities, except in the case of teeth with pulpectomies or pulpotomies. The placement of compomers takes longer than placing amalgam, but the procedure consists of fewer steps compared to composites. However, patient-compliance remains essential
