Effect of maxillary impacted canine teeth on root resorption of adjacent teeth: a CBCT-based observational study.
Observational study in BMC oral health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 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
backgroundThe aim of this study was to investigate the effect of impacted maxillary canines on root resorption and periodontal tissues of adjacent central, lateral, and premolar teeth across different age groups using Cone Beam Computed Tomography (CBCT) imaging.
methodsCBCT images of 203 impacted maxillary canines from patients of varying ages were retrospectively evaluated. Parameters included eruption stage, localization (right/left and palatal/buccal/central), dental follicle characteristics (shape and width), contact with adjacent teeth, periodontal contour integrity, and degree and location of root resorption. Statistical analyses assessed the relationships between these variables.
resultsA total of 203 impacted maxillary canines, including 123 on the right and 80 on the left side, were assessed. Impacted canines were most commonly affected with lateral teeth (57.6%). Root resorption occurred in 33.3% of these lateral teeth, with 14.5% showing severe resorption. Mild resorption was most frequently observed in central incisors and first premolars (16.7% and 12.5%, respectively). Root resorption was significantly more frequent when impacted maxillary canines were in contact with adjacent teeth (p = 0.005 for central incisors, p < 0.001 for lateral incisors, and p = 0.012 for premolars). No significant difference was found between genders in terms of root resorption (p > 0.05). Impacted canines were most commonly located in the palatal position (73.4%), but no statistically significant difference was found in root resorption rates between palatal, buccal, and central positions (p = 0.490). Canine follicle shape, width, and eruption stage did not significantly affect root resorption (p > 0.05).
conclusionPalatal position and contact of impacted maxillary canines with adjacent teeth increase root resorption frequency, especially affecting lateral incisors. CBCT provides accurate diagnostic information that supports clinical decision-making for impacted canine cases.
