CBCT Evaluation of the Relationship Between Mandibular Molars and the Inferior Alveolar Canal in a Peruvian Population.
Review in Journal of clinical and experimental dentistry, 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
Background: Proximity between the inferior alveolar canal and mandibular molar apices is a critical factor in oral surgery and implant dentistry, as it may increase the risk of nerve injury. Cone-beam computed tomography (CBCT) enables precise three-dimensional evaluation of this relationship; however, evidence in Peruvian populations remains limited. Material and Methods: A descriptive cross-sectional study was conducted using 177 CBCT scans obtained from the IRM Radiological Center in Trujillo, Peru (2024-2025). The distance between the inferior alveolar canal and the apices of mandibular first and second molars was measured at the mesial and distal roots. Descriptive statistics were calculated, and differences according to age and sex were assessed using Student's t-test and the Kruskal-Wallis test (p < 0.05). Results: First mandibular molars showed greater distances from the canal, with mean values of 5.1 mm in mesial roots and 4.3-4.4 mm in distal roots. Second molars presented shorter distances, particularly in distal roots (2.5-2.6 mm). No significant differences were observed among age groups (p > 0.05). Male patients showed greater distances than females, with significant differences in mesial roots (p < 0.05). Conclusions: Second mandibular molars are located closer to the inferior alveolar canal than first molars. CBCT provides clinically relevant information for surgical planning and may help reduce the risk of inferior alveolar nerve injury.
