“…carried out a study among Jordanian dentists and reported that few dentists (13.8%) had knowledge of the Minamata Convention, and only 17% of the study population had undergraduate orientation in support of restoring posterior teeth with composite. They also revealed that only 28.1% of these practicing dentists were convinced that amalgam should be discontinued in consideration of the reported health and environmental safety concerns. The senior resident doctors in the present study were more likely than the younger clinicians to place resin composite and GIC restorations, this may be as a result of this senior group of dentists being more confident in the use of these adhesive materials, which are more technique sensitive in comparison to the placement of amalgam restorations.…”

Objective: The Minimata Convention on mercury includes amalgam phase-down and eventual phase-out from dentistry. To aid its subsequent evaluation it is important to have baseline data of amalgam use in a locality prior to implementing a phase-down. Methodology: Records of patients spanning 5 years from January 2011 to January 2016 were analysed to determine and the compare frequency of amalgam usage with other dental materials for carious teeth restorations in a Nigerian university teaching hospital. Classes of cavities restored and cadres of operators who employed the different materials were included. Institutional ethics committee approval was obtained prior to commencing the study. Results: 2,058 patients' records were retrieved, 59% females and 41% males. Their ages ranged 19-80 years, mean 33.5 AE 12.7 years, young adults 20-39 years old were the majority (62.9%). Filling materials included 57.5% amalgam, 17.6% glass ionomer cement (GIC) and 24.9% resin composite. Class I restorations constituted 70.5% of amalgam restorations, while Class II restorations made up 29.4% and Class V restorations accounted for 0.1%. Undergraduate dental students placed most of the amalgam restorations (60.5%), and 78.9% of all their restorations were amalgam. Less experienced dentists used all materials equally; the more experienced dentists placed more composite resin and GIC (43.3%). Conclusion: Amalgam fillings constituted nearly 60% of the restorations of carious teeth. Training of dental students in placement of non-mercury alternatives to amalgam and Minimum Intervention Dentistry needs to be emphasized in dental schools. Phase-down of amalgam should be intensified in Nigeria with the ultimate aim of a phase-out in line with the Minamata Convention.

“…Al-Rabab'ah et al 11 reported an even lower percentage of Jordanian dentists (17%) who had received undergraduate training in placement of posterior resin composite. 11 Dentists who completed their undergraduate studies before the implementation of the Minamata Convention would have received training in restorative dentistry focused on amalgam, and these professionals are most likely to resist the shift from amalgam to other restorative dental materials. Our findings highlight the need to conduct continuing dental education in adhesive/operative dentistry at several easily accessible centres across the country to impart this knowledge to dentists lacking operative dental skills in the area of adhesive dentistry.…”

“…Over 50% (52.4%) were unaware, 13.2% were unconvinced, and 39.2% were uncertain regarding the health hazards associated with the mercury content of amalgam specified by the UNEP and other international bodies. Al-Rabab'ah et al 11 also reported that only 28.1% of Jordanian dentists were convinced that amalgam use needs to be discontinued owing to the alleged health and environmental hazards associated with its use. 11 Of the 741 participants with poor knowledge of the Minamata Convention, 31 (4.2%) admitted to adopting good phase-down practices, which could be attributed to the increasing demand for tooth-coloured restorative materials by patients.…”

“…This treaty led to a global paradigm shift in dentistry (both at the undergraduate and post-graduate operative levels) to encourage the adoption of minimally invasive approaches to dental restorations. 11 Currently, mercury-free dental restorations are the mainstay of treatment used by dental students and dentists in several countries. 12,13 Therefore, dental education continues to show a steady shift in focus from amalgam to non-amalgam restorative materials, and amalgam use will most likely be restricted to pre-clinical settings, following a phase-out in the future.…”

Background: Amalgam is one of the most reliable dental restorative materials. Health and environmental concerns associated with the mercury content of amalgam have necessitated an amalgam phase-down in clinical practice. Objectives: This study investigated the level of awareness and preparedness for the planned amalgam phase-down recommended by the Minamata Convention amongst Nigerian dental students and dentists. Methods: This cross-sectional national survey was performed across all geopolitical zones of Nigeria. Data regarding awareness, practice and level of preparedness for amalgam phase-down were obtained using a questionnaire that was distributed amongst clinical dental students and dentists of different cadres, who routinely place dental restorations, in public and private practice. The questionnaires were administered online or were hand delivered. Data were analysed using the chi-square test and Spearman's rank correlation coefficient. A p value ≤ 0.05 was considered statistically significant. Results: Notably, 845 dental students and dentists participated in the survey. Mean age (±standard deviation) of participants was 30.15 ± 7.67 years, 33.8% were students, and 66.2% were dentists (most dentists [77.1%] were employed at public hospitals). A significant percentage of respondents had poor knowledge of the Minamata | 667 MAKANJUOLA et AL. How to cite this article: Makanjuola JO, Umesi DC, Ndukwe AN, et al.

This review was conducted to assist the busy dentist in keeping abreast of the latest scientific information regarding the clinical practice of dentistry. Each of the authors, who are considered experts in their disciplines, was asked to peruse the scientific literature in their discipline published in 2016 and review the articles for important information that may affect treatment decisions. Comments on experimental methodology, statistical evaluation, and the overall validity of conclusions are included with many of the reviews. The reviews are not meant to stand alone but are intended to inform the interested reader about what has been discovered in the past year. The readers are then invited to go to the source, if they want more detail.
