Prevalence of palatogingival groove and its association with periapical lesions and periodontal bone loss: a cone beam computed tomography study.
Article 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 1 paper.
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
backgroundThis study aimed to evaluate the prevalence of palatogingival groove (PGG) in maxillary incisors and its association with periapical lesions and periodontal bone loss.
methodsCBCT images from 943 patients were included. Age, sex, and the presence of PGG were recorded. PGG type was determined according to the Gu classification. All maxillary incisors of patients with PGG teeth were evaluated for periapical lesions and periodontal bone loss. Statistical analysis was performed with the Pearson chi-square test and Fisher's exact test.
resultsPGGs were present in 107 maxillary incisors (2.8%) of 89 patients (9.4%). PGGs were observed significantly less frequently in maxillary central incisors than in maxillary lateral incisors (p < 0.001). The most common PGG was type I (75.7%), followed by type II (15.9%) and type III (8.4%). PGGs were associated with periapical lesions and periodontal bone loss (p < 0.001). PGG teeth without periapical lesions or periodontal bone loss were mostly type I. When the PGG was type II or III, the teeth mostly had periapical lesions and periodontal bone loss (p < 0.001). A significant relationship was detected between the periapical lesion status and bone loss status in PGG teeth (p < 0.05).
conclusionsPGGs were found mostly in maxillary lateral incisors. Most teeth with type II and III PGGs were characterized by periodontal bone loss and periapical lesions. Additionally, most PGG teeth with periodontal bone loss had periapical lesions. These findings imply that the presence of a PGG should be suspected in a maxillary incisor with a narrow periodontal pocket and periapical lesion but no caries, cracks, or restorations.
