Linking facial typology to dental morphology and gingival characteristics: a cross-sectional study.
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
backgroundContemporary orthodontic planning increasingly recognizes the importance of periodontal soft-tissue morphology. Thin gingiva is more susceptible to recession and may limit safe tooth movement. The evidence regarding the relationship between facial and gingival morphology is inconsistent. The aim of the present study was to investigate the associations between facial typology, gingival and dental characteristics in periodontally healthy young adults. METHODOLOGY: Facial measurements included facial height (N-Me), facial width (Zy-Zy) and facial index (FI = N-Me/Zy-Zy). Periodontal examination included the determination of gingival phenotype (GP) by periodontal probe visibility method, measurement of the width of attached gingiva (AG) and ultrasonic measurement of gingival thickness (GT). Additionally, crown width (CW) and clinical crown height (CCH) were measured.
resultsSixty-one patients (aged 21-30), 43 females and 18 males participated. CW of maxillary and mandibular central incisors demonstrated significant positive correlations with Zy-Zy. GT at teeth 22 and 42 correlated positively with Zy-Zy, while GT at teeth 31 and 32 correlated negatively with FI. A significant positive association was observed between AG at multiple teeth and N-Me. Male sex emerged as an independent predictor of GT at 22 and 42 and AG at 11, 42, 41, 31 and 32, while increasing FI was associated with reduced GT at 31 and 32.
conclusionsIndividuals with broader faces seem to present wider central incisors and thicker gingival tissues. Subject with greater facial height may present wider zone of attached gingiva at incisors. In males, gingiva may be thicker and of a wider band of attached tissues.
