Amalgam restorations for primary molars in clinical practice and dental schools: current situation and required changes.
Article in BMC oral health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06995859 (Amalgam Restorations Teaching in Pediatric Dentistry in Egyptian Universities), which is not on this map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Abstract
backgroundThere is a considerable debate in clinical practice regarding the use of amalgam restorations in primary molars. The current study aimed to assess the weight of teaching amalgam cavity preparation and restoration in various pediatric dentistry programs in Egypt, as well as the perceptions of pediatric dentistry educators regarding the teaching and use of dental amalgam as a restoration for primary molars. Additionally, this study sought to correlate the data with the respondents’ demographic data.
methodsA 24-question web-based questionnaire was created, validated, and sent to heads of pediatric dentistry departments in 30 dental schools in Egypt. The questionnaire was asked to be completed and shared with the teaching staff. The data gathered were exported into an Excel spreadsheet and statistically analysed. Spearman’s rank correlation coefficient and chi-square test for independence were used to assess associations between demographic variables and several statements from the questionnaire.
resultsA total of 139 respondents from 26 schools were included in the data analysis. 21 and 7 schools teach amalgam in undergraduate and postgraduate programs, respectively. 88% of the respondents have not used amalgam for a year or more, 73% will have no actual effect on their practice if amalgam were not an available option. 21% and 42% disagree with continuing to teach amalgam in undergraduate and postgraduate programs, respectively. Statistically significant relations were found between the age, years of experience, type of institution of respondents, and respondents’ agreement with the different statements from the questionnaire concerning the continuation of use and teaching amalgam, as well as increasing the time dedicated to teaching adhesive restorations.
conclusionsFor most paediatric dentistry faculty members, amalgam is not the best choice for restoring primary molars; however, they are cautious and not yet ready to discontinue teaching amalgam, especially among the older and more experienced faculty members. They also believe that the number of training hours dedicated to adhesive restorations should be increased. REGISTRATION: The current study was registered on clinicaltrials.gov on May 28, 2025, with the identifier number NCT06995859.
