“…A defective amalgam restoration is not a good sign since it can ruin the tooth's health and also cause secondary caries. But it can be prevented by facilitating contaminant free bonding and also by reducing microleakage.Most of the respondents of the survey preferred replacing the amalgam restoration, rather than repairing, as they found repair increases the longevity of the restoration and will serve the purpose .Repair of defective amalgam restorations are technique sensitive and requires operator skill (Popoff et al, 2011). Though respondents agreed repair would be a valid option, their confidence level in performing these treatments were not good, which made them prefer replacement over repair.…”

Background: Dental restorations were a requirement since the time dental cavities have been prevalent in humans and that has been so for ages and it has not always been treated the best way. The time and availability of the technique and methods as it is now were not so in the earlier times. Amalgam restorations are one of the old restorative materials that are to be performed with great skill, patience, and proper technique. Defective amalgam restorations can be made to serve the purpose with the advent of repair techniques. Aim: To assess the knowledge and perception regarding the management of defective amalgam restorations among dental practitioners in Chennai. Methods: A survey questionnaire regarding the management of defective amalgam restorations was prepared on a survey platform and distributed among 100 dentists randomly to analyze the perception of the participants towards the management of defective amalgam restoration. The survey questions are such that they try to assess the knowledge, experience, and the level of improvisation of the dentists regarding the repair of amalgam restorations. Convenient sampling was done and a sample size of 100 was chosen. The results obtained from the survey were then analyzed using SPSS 22.0 and the chi square test was done to assess the significant association between the field of practice and their responses to the questions and the graphs were plotted. Results: From the survey results it was evident that the dental practitioners find removal and replacement quite hectic and hence would like to have the alternate option of repair of the existing restoration if it is possible. Repair does seem to be a valuable idea on ways to manage defective amalgam restorations Repairing an amalgam restoration would save time for the dentist and money for the patient but due to the lack of certain techniques and instruments, it is not widely practiced. Replacement is mostly carried out for management of defective amalgam restorations. It does involve more time and expense but the purpose of managing a defective amalgam restoration is served.There was no significant association between the field of practice of the dentists (specialists/ general practitioners) and their response to the question for the majority of the survey questions. Conclusion:Repair does seem to be a valuable idea on ways to manage defective amalgam restorations rather than replacing it, but majority of the participants preferred replacing the restoration as they were not confident on methods to repair, and believed replacement would benefit the patients by increasing the longevity of the restoration.

“…Adhesive systems have been developed (and continue to be developed) in order to eliminate the microleakage that has caused problems for both the traditional amalgam and other restorations (17)(18)(19)(20)(21)(22)(23). Adhesives are commonly used in dentistry today.…”

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.

Background:Microleakage is one of the most frequently encountered problems in posterior tooth-colored restorations. Efforts to decrease this problem with resin restorations include techniques for reducing the ratio of bonded to unbonded restoration surfaces and following strategic incremental placement techniques to reduce residual stress at tooth-restoration interface which reduces the C-factor, hence microleakage.Aim:The present study aimed to evaluate microleakage associated with three placement techniques for compomer restorations in primary molars.Design and Methodology:This in vitro experimental study assessed the microleakage associated with bulk-fill, horizontal-incremental, and oblique-incremental compomer placement techniques in primary molars. Ninety specimens were divided into three groups of thirty for each of the placement techniques.Results:Nearly 86.6% of the specimens presented with microleakage involving the entire axial wall and pulpal floor in the bulk-fill group, whereas 56.6% and 46.6% of the specimens in the horizontal-incremental and oblique-incremental groups showed microleakage up to two-third and one-third of the axial walls, respectively. A significant difference in scores was observed between groups (P < 0.001).Conclusion:Microleakage was observed with all the three techniques but was comparatively lower with the incremental placement techniques. The oblique-incremental technique offered the least microleakage.

Repair of amalgam restorations with composite resin and bonded amalgam: A microleakage study

Abstract: The use of adhesive systems significantly affected the ability to seal the repair/ tooth interface. However, at the level of the repair/restoration interface, the bonded amalgam technique may increase microleakage.
