Menarchal status as an indicator of mandibular second molar maturation in female adolescents.
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
backgroundMenarchal status is a key pubertal milestone in females, yet its relationship with dental maturation has not been adequately explored using multivariate approaches. This study aimed to evaluate the association between menarchal status and mandibular second molar calcification stages in female adolescents, and to determine whether menarchal status is associated with dental maturation after controlling for chronological age and vertical facial pattern.
methodsThis retrospective cross-sectional study included 180 Turkish female patients aged 9-16 years, equally distributed into three groups: pre-menarche (n = 60), early post-menarche (0-1 year, n = 60), and late post-menarche (> 1 year, n = 60). Mandibular second molar calcification was assessed using the Demirjian index (stages D-H). Chronological age across groups was compared using the Kruskal-Wallis test with Dunn post-hoc comparisons. Demirjian stages were analysed using the Kruskal-Wallis test with post-hoc comparisons, Spearman correlation, and ordinal logistic regression analysis controlling for vertical facial pattern (α = 0.05).
resultsDemirjian stage distribution differed significantly across menarchal groups (H = 110.49, p < 0.001), with median stages progressing from E to G to H. Menarchal status showed a strong positive correlation with dental maturation (ρ = 0.785, p < 0.001). In multivariate analysis, menarchal status was significantly associated with Demirjian stage (OR = 26.82, 95% CI: 13.66-52.68, p < 0.001); however, the magnitude of this effect partly reflects the equal-group design, and model fit was comparable to that of chronological age (AIC: 377.3 vs. 379.6).
conclusionsMenarchal status is strongly associated with mandibular second molar maturation, with model fit comparable to chronological age. These findings suggest that menarchal history may serve as a clinically accessible, non-invasive biological marker to complement dental maturation assessment in orthodontic treatment planning.
