Shades of knowledge: awareness among Brazilian dentists on non- and microinvasive approaches for tooth discoloration.
Observational study in Journal of applied oral science : revista FOB, 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
objectiveTooth discoloration is a frequent concern among dental patients. While many professionals and patients choose veneers or other invasive solutions, Minimal Intervention Dentistry (MID) recommends non- and microinvasive approaches to preserve tooth structure. To assess Brazilian dentists' knowledge and practices on tooth discoloration and how education and professional profile may influence them. METHODOLOGY: A cross-sectional observational study was conducted with 384 volunteer dentists via an online series of questions on causes, diagnosis, treatment (per tissue removal), and professional-patient relationship. Answers were scored (1=correct/affirmative, 0=incorrect/negative). Descriptive and multivariate regression analyses were performed (α=0.05).
resultsMost respondents were female, aged 20-49, from the Southeast region. Correct answer rates: 69.9% for causes, 69.4% for diagnosis, 48.8% for treatment, 83.6% for professional-patient relationship, 56.4% overall. Graduation from public universities and holding graduate training in Operative or Pediatric Dentistry or Orofacial Harmonization were associated with better outcomes.
conclusionKnowledge of non- and microinvasive approaches to tooth discoloration remains limited. Broader educational efforts are needed, especially among specific groups of professionals who showed lower performance.
