Free gingival groove as a landmark for anatomical crown length in altered passive eruption.
Article in Journal of Indian Society of Periodontology. 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: Identifying the cementoenamel junction (CEJ) in patients with altered passive eruption (APE) can be challenging during esthetic crown lengthening. The free gingival groove (FGG) may serve as a useful landmark for estimating CEJ position. This study evaluated the agreement between FGG and surgically identified CEJ, and explored additional photographic variables for CEJ prediction when FGG was not clearly identifiable. Materials and Methods: This retrospective study analyzed presurgical and flap-reflected intraoral photographs of teeth 13-23 from 48 patients with APE who underwent esthetic crown lengthening at a university periodontal clinic. Proportion-based measurements were obtained in ImageJ by a calibrated examiner. The percentage of crown width to the distance from the incisal edge to the FGG (%WIFR) was measured on presurgical photographs, and the percentage of crown width to anatomical crown length (%WALR) was measured on flap-reflected photographs as the reference for CEJ position. Results: %WIFR showed strong agreement with %WALR across all teeth ( Conclusions: Standardized intraoral photographs can support clinically applicable CEJ estimation in APE, using the FGG as the primary landmark and a proportion-based prediction model as an alternative approach.
