Dentists' knowledge, skills, attitudes and barriers towards minimal intervention dentistry.
Article in Brazilian oral research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the 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.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
This cross-sectional study evaluated the knowledge, skills, attitudes, and perceived barriers of dentists from the Federal District, Brazil, regarding Minimal Intervention Dentistry (MID). A validated online questionnaire was administered using non-probabilistic snowball sampling, and 404 dentists participated (74% female; mean professional experience: 12 ± 10.9 years). Data were analyzed using descriptive and inferential statistics, including multiple linear regression (p < 0.05). The dependent variables were knowledge, skills, attitudes, and barriers, while the independent variables included administrative region, years of professional experience, type of graduation institution, academic qualification, professional role, and information-seeking behavior. Overall, participants demonstrated high levels of competency in MID, particularly in the preventive and diagnostic domains; however, selective carious tissue removal was the procedure performed least frequently (38.6%). Regression analyses showed that dentists involved in teaching or research reported significantly fewer barriers (β = -2.56; 95% CI: -3.90 to -1.23; p < 0.001). Dentists who had received formal training in MID achieved higher scores in knowledge (β = 2.95; 95%CI: 2.31 to 3.59; p < 0.001) and in skills and attitudes (β = 3.40; 95%CI: 2.18 to 4.62; p < 0.001), as well as fewer perceived barriers (β = -1.52; 95%CI: -2.35 to -0.68; p < 0.001). Information-seeking behavior was positively associated with greater knowledge (β = 2.35; 95%CI: 1.56 to 3.14; p < 0.001) and improved skills and attitudes (β = 3.06; 95%CI: 1.55 to 4.56; p < 0.001). Graduates from public universities presented higher scores for skills and attitudes (β = 2.17; 95%CI: 1.15 to 3.18; p < 0.001) and reported fewer barriers (β = -0.88; 95%CI: -1.61 to -0.15; p < 0.01). Brazilian dentists demonstrated a strong theoretical understanding of MID; however, practical implementation remains limited. Academic background, involvement in education and research, and proactive learning behaviors were key determinants of higher competency levels and reduced barriers to the adoption of MID.
