Objective:
This scoping review aimed to map the knowledge, perceptions, and attitudes of dental professionals and students regarding MIH.
Materials And Methods:
A systematic search was conducted in the electronic databases MEDLINE/PubMed, Scopus, Web of Science, and Embase up to May 2023. A search in the OpenGrey database for grey literature was also performed. The reference lists of potentially eligible studies were checked to ensure that all relevant studies were analyzed. Scientific papers were considered eligible if they met the specified inclusion criteria: (1) focused on MIH; (2) assessed the knowledge/perception/attitudes of oral health professionals. Scientific papers were deemed ineligible if they met any of the following exclusion criteria: (1) lacking data on the knowledge/perception/attitudes regarding MIH among dental health professionals and students; (2) being a literature review/expert opinion/systematic review/case report.
Results:
207 potentially eligible studies were identified, and 35 studies were included. A clear distinction emerged between qualified dental professionals and students regarding knowledge, attitudes, and management of MIH. Globally, variability was evident: Australia/New Zealand demonstrated strong protocols, China/Chile reported substantial gaps, and the UK showed mixed performance. Treatment preferences differed, with Saudi Arabia favoring stainless steel crowns/composite resin and Malaysia using glass ionomer cement/composite resin.
Conclusion:
Knowledge, attitudes, and management of MIH differ significantly across professional levels and countries. Specialists and general dentists show greater confidence in diagnosing and treating MIH than students, though variations exist within both groups. The systematic review protocol was registered in OSF platform (doi: 10.17605/OSF.IO/NHMV2).
