Eruptive path of maxillary canines in patients with lateral incisor agenesis: a longitudinal follow-up.
Article in The Angle orthodontist, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper, 1 of them a synthesis that pooled it.
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
objectivesTo evaluate the eruptive angle, mesiodistal position and height of permanent maxillary canines in patients with agenesis of the permanent maxillary lateral incisor (AL) from the mixed to the permanent dentition. MATERIALS AND
methodsThe sample was composed of orthodontic records of subjects with and without AL. The agenesis group comprised 11 patients, 7 with bilateral and 4 with unilateral AL (8.6 ± 1.6 years, 4 males, 7 females). The control group comprised 9 patients (8.5 ± 1.0 years, 2 males, 7 females) without AL. Panoramic radiographs were analyzed at three timepoints: inter-transitional period (T1), second transitional period (10.1±0.9 years, T2) and permanent dentition (11.9±1.1 years, T3). The long axis angle of the permanent maxillary canine (α and β), the mesiodistal distance (d) in relation to the central incisor, and the height (H) from the cusp tip of the canine to the occlusal plane were evaluated. Intergroup comparisons were performed with t-tests, Mann-Whitney, and Chi-square tests (P < 0.05).
resultsA mesial position of the canine cusp tip relative to the distal of the permanent maxillary central incisor was observed for the agenesis group at T1, T2 and T3. From T1 to T2, the agenesis group showed greater occlusal displacement of the canine tooth germ.
conclusionsIn patients with AL, canine tooth germs showed more mesial displacement and erupted a mean of 4.5 mm closer to the maxillary central incisors. Eruption of maxillary canines tended to be accelerated during the late mixed dentition in patients with AL.
