Abstract:
Background: The philosophy of minimum interventional dentistry (MID) is to integrate
prevention, remineralization, and minimal intervention for the placement and replacement of restora-
tions. All branches of dentistry play an important role in practicing MID, and their primary goal is to
realize that any restoration is of less biological significance than the healthy original tissue Objectives:
The objective of this study was to assess the perception of MID among dental undergraduate students
and interns in terms of knowledge, attitude, and practice at the College of Dentistry. Materials and
Methods: This cross-sectional study was conducted among undergraduate students and interns at
the College of Dentistry, Qassim University, Saudi Arabia. A self-administered questionnaire was
distributed, which included basic demographic profiles and questions about the knowledge, attitude,
and practices toward MID. The data were tabulated in MS Excel, and all statistical analyses were
performed using SPSS version 21. Results: A total of 163 dental students were recruited, with senior
students comprising 73% and interns comprising 27%. Male students were slightly more prevalent
(50.9%) than female students (49.1%). About 37.6% of participants received training about MID during
educational courses, while 10.3% received it during their internship. A statistical test revealed that
the prevalence of interns who were trained in performing MID was significantly higher (p < 0.001).
Conclusions: The majority of the participants demonstrated proper knowledge, attitude, and practice
in different aspects of MID. Interns reported a higher rate of knowledge, attitude, and practice in
MID compared to undergraduate students. However, more education and hands-on training about
MID concepts during the college curriculum are necessary to attain better knowledge, attitude, and
practices that could be useful for more conservative clinical practice.
