Development and validation of the Dental Artificial Intelligence Readiness and Acceptance Instrument (DAI-RAI) for dental professionals.
Article in BMC oral health, 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
backgroundArtificial intelligence (AI), including applications such as radiographic image analysis, caries detection, and treatment planning, is increasingly integrated into dental diagnostics, education, and clinical workflows. However, validated instruments to evaluate dental professionals' preparedness for AI remain limited, particularly those capturing both readiness and acceptance in clinical contexts. This study developed and psychometrically validated the Dental Artificial Intelligence Readiness and Acceptance Instrument (DAI-RAI) to assess readiness and acceptance toward AI adoption in dentistry.
methodsItems were constructed based on the Technology Readiness Index (TRI) and Technology Acceptance Model (TAM), adapted to the dental AI context, and refined through expert review and pilot testing. The final validation sample included 941 dental professionals. Exploratory factor analysis (EFA) using Maximum Likelihood with Varimax rotation examined factor structure, followed by confirmatory factor analysis (CFA) using AMOS and R. Internal consistency and convergent validity were evaluated using Cronbach's alpha (α), Composite Reliability (CR), and Average Variance Extracted (AVE).
resultsSampling adequacy was confirmed using the Kaiser-Meyer-Olkin (KMO) measure, which was excellent (KMO = 0.95; Bartlett's χ²= 6640.32, p < 0.001). EFA supported a two-factor solution accounting for 61.8% of the variance, and one low-loading item (loading = 0.37) was removed based on the predefined threshold of ≥ 0.40. CFA indicated an acceptable overall fit (CFI = 0.915; TLI = 0.900; SRMR = 0.047), although RMSEA (0.108) suggested moderate model misfit. The final validation was conducted on a large sample of dental professionals (N = 941). The final instrument, comprising two modified constructs, AI-Technology Readiness (AI-TR) and AI-Technology Acceptance (AI-TA), consisted of 15 items (AI-TR = 8, AI-TA = 7). The DAI-RAI demonstrated excellent reliability and convergent validity (AI-TR: α = 0.92, AVE = 0.621; AI-TA: α = 0.94, AVE = 0.659). Partial measurement invariance was established across professional roles.
conclusionThe DAI-RAI is a concise, reliable, and theory-grounded measure that evaluates dental professionals' AI readiness and acceptance. Its validated structure supports its application in educational planning, workforce development, and the ethical implementation of AI in dental care.
