title: The concepts of minimally invasive dentistry and its impact on clinical practice: a survey with a group of Brazilian professionals.
abstract: This cross-sectional study aimed to assess the knowledge and attitudes of 123 Brazilian dentists in relation to the concepts and practice of minimally invasive dentistry (MID). Data were collected through a questionnaire developed and validated by experts. Statistical analysis was performed using an spss program and Pearson's chi-square test. Most participants had up to 10 years experience after graduation (69.9%), were specialised (60.2%) and worked in public and private service (43.1%). Regarding current concepts of dental caries, 87.0% were unaware and 65.9% answered that the treatment involves only the restorative phase. In relation to caries lesion arrest, 39.8% replied that it depended on the total removal of carious tissue. Most of them were aware of MID procedures (82.1%) but 49.6% did not follow them in daily practice. From these participants, 48.4% did not believe in the technique or did not know how to perform it. Decisions on partial or total removal of carious dentine, behaviour in relation to the procedures (permanent or temporary) and the practice of MID were not influenced by how long since the professionals had graduated or become specialised. It can be concluded that scientific evidence reaches most of the professionals, but does not benefit all patients, as many practitioners still follow the principles of total removal of carious tissue. Teaching should include making professionals fully aware of the carious process and encourage them to fully adopt the techniques and attitudes of MID.
