Amalgam Restorations

Aim: The purpose of this study was to evaluate the effectiveness of different adhesive systems in amalgam restorations and their effects on microleakage. Methodology: In this study, 105 caries-free extracted human permanent molar teeth were used. Teeth were randomly assigned to five groups (n=21), and class I cavities were created on the surface of each tooth. The first was a control group to which no adhesive system was applied. Amalgam Liner (VOCO GmbH, Cuxhaven Germany) was applied to Group II, Clearfil SE-Bond (Kuraray Europe GmbH, Frankfurt Germany) was applied to Group III, Panavia F 2.0 (Kuraray Europe GmbH, Frankfurt Germany) was applied to Group IV, Amalgambond Plus (Parkell Inc.Edgewood, NY USA) was applied to Group V, and then amalgam (Tytin, Kerr, California USA) restorations were placed. After the polishing process, samples were subjected to thermocycling 1,000 times. Teeth were sectioned bucco-palatinally/lingually, and microleakage scores of the occlusal walls were evaluated under a stereomicroscope at 15X magnification by a standardized scale ranging from 0 to 4. One tooth was selected randomly from each group for SEM (Scanning Electron Microscope), and SEM LEO EVO 40 (LEO Ltd., Cambridge UK) photographs of amalgam-tooth hard tissue interfaces were also taken at different magnifications. The results of the microleakage tests were statistically analyzed by both the Kruskal-Wallis Test and the Mann Whitney U Test. Results: In terms of microleakage among groups, the differences that were determined were significant (p<0.05). Microleakage within the control group was determined to be the highest, and statistically important differences were observed between the other groups. Group V (Amalgambond Plus) was determined to have the lowest microleakage scores. Conclusion: In prepared class I cavities, amalgam adhesive systems are effective in preventing occlusal microleakage but do not completely blocked it.   How to cite this article: Ünal M, Atakul F.

Amalgam Restorations

Dental amalgam continues to be an important restorative material; both fundamental and applied research should be encouraged. The criteria for replacement of amalgam restorations should be re-examined to determine if the integrity of the margins should continue to receive the dominant research interest. In the studies of mechanical properties, first attempts have been made to apply fracture mechanics analysis to dental amalgam. The heterogeneous structure and time-dependent strain of dental amalgam will have to be considered in future studies. More attention should be given to the effects of zinc, which has been shown to improve resistance to marginal fracture. The corrosion properties have been studied in depth, but there are some important unanswered questions. The pathways of corrosion attack in high-copper amalgams and the kinetics of attack in amalgams of different composition should be examined. Biocompatibility of dental amalgam has recently received renewed interest and will have to be examined in more detail. The clinical significance of the release of metallic elements from restorations is generally unknown. Dental amalgam faces strong competition from non-metallic restorative materials. Future research should be more strongly focused on the critical issues. The involvement of scientists from related disciplines should be encouraged, and no effort should be made to restrict the talent pool by a centralization of resources.
