Investigation of dermatoglyphic patterns for mandibular retrognathism or maxillary prognathism as a novel diagnostic approach for skeletal Class II malocclusion.
Article in BMC oral health, 2025. 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
backgroundDermatoglyphics, the study of fingerprint patterns, is derived from the ectoderm, the same embryological layer responsible for craniofacial development. Its potential as a non-invasive diagnostic tool has been explored in various medical and dental conditions, including skeletal Class II malocclusion.
objectiveThis study aims to evaluate the correlation between dermatoglyphic patterns and cephalometric angles (SNA and SNB) in Class II skeletal malocclusion to establish a novel diagnostic approach. MATERIAL AND
methodsA total of 100 participants (aged 18:35 years) diagnosed with skeletal Class II malocclusion were evaluated. The participants were divided into two groups: 50 with increased SNA (> 84°) and 50 with decreased SNB (< 78°). Dermatoglyphic patterns, including Whorls, Loops, Tented Loops, Central Pockets, and Arches, were analyzed for all 10 fingers using the ink-and-stamp method. Cephalometric measurements were conducted using standardized lateral cephalogram. Statistical analyses, including Chi-Square tests and correlation analysis, were performed to identify significant associations.
resultsWhorl patterns were most associated with increased SNA, while Plain Loops correlated significantly with decreased SNB. The middle finger (F3) and Index finger (F7) emerged as the most reliable indicators of skeletal discrepancies. Chi-Square analysis confirmed a statistically significant association between fingerprint patterns and cephalometric measurements (p < 0.001).
conclusionDermatoglyphic patterns, particularly Whorls and Loops, demonstrate strong correlations with SNA and SNB angles in skeletal Class II malocclusion. This study establishes dermatoglyphics as a non-invasive, reliable diagnostic tool for early detection and personalized treatment planning in orthodontics.
