Periosteal Fenestration Procedure in Apically Positioned Flap Increases the Attached Mucosal Width: An In Vivo Experimental Study.
Article in Journal of clinical periodontology, 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
aimTo evaluate the efficacy of the apically positioned flap (APF) with periosteal fenestration in increasing the width of the masticatory mucosa (MM, including attached and keratinized mucosa) and to assess the histological properties of the MM gained through this technique. MATERIALS AND
methodsSix mongrel dogs were treated using a split-mouth design, with APF alone (control) and APF with periosteal fenestration (test) applied from the first to the fourth maxillary premolars on both sides (total of 48 sites). Clinical MM width (cMW) and digitally scanned MM width (dMW) were measured at baseline, post-operatively, and after 8 weeks of healing. Histological observations included measuring the distance from the free gingival margin to the mucogingival junction (MGJ) and the width of non-keratinized attached mucosa (NKAM). A linear mixed model was employed to analyse changes in MM measurements.
resultsThe mean gain of cMW was 3.17 mm (SD 1.63) in the control group and 4.27 mm (SD 1.91) in the fenestration group with a significant difference in favour of the fenestration group. The estimated mean difference was 1.45 mm (95% CI: 0.57-2.33; p = 0.002). Histologically, the increased mucosal width observed in the fenestration group, compared to the control group, was primarily characterized by non-keratinized epithelium.
conclusionAPF with periosteal fenestration enhances the attached mucosal width; however, this increase is predominantly composed of NKAM rather than orthokeratinized mucosa.
