Analytical validation of Smilo.ai: evaluating an AI-driven platform for automated oral health screening and global diagnostic accessibility.
Article in Frontiers in 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
Background: Oral diseases affect more than 3.5 billion people worldwide and remain among the most neglected global health challenges. Access to preventive oral healthcare is constrained by workforce shortages, transportation barriers, and patient apprehension toward dental procedures. Artificial intelligence (AI)-enabled diagnostic systems offer scalable solutions for early detection and triage through non-dental personnel. This study presents the Phase 1 analytical validation of Smilo.ai, an AI-driven platform designed for automated detection of common oral health conditions using standardized digital oral photographs. Methods: A cross-sectional validation study was conducted among 45 adult participants in a community-based oral health screening program in India between February 1 and 10, 2025. Each participant contributed one composite oral image containing four standardized views (frontal, left lateral, right lateral, and occlusal), yielding an analytical dataset of 45 images ( Results: Smilo.ai demonstrated an overall sensitivity of 73.6%, precision of 46.0%, accuracy of 47.3%, and a macro-level Cohen's Conclusion: This Phase 1 validation establishes a performance baseline for Smilo.ai and identifies optimization priorities, including positive prediction bias correction and threshold recalibration necessary before screening workflow integration. AI-assisted screening models hold significant promise for improving preventive oral healthcare access among underserved populations. The upcoming Phase 2 validation will evaluate clinical generalizability through synchronous clinical examinations to confirm real-world applicability.
