Prevalence and Contributing Factors of Mandibular Labial Gingival Recession in Patients With Lingual Orthodontic Retainers: A Cross-Sectional Study.

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
objectivesTo investigate the prevalence and contributing factors of mandibular labial gingival recession in patients with fixed lingual orthodontic retainers.
methodsThis cross-sectional study involved 83 post-orthodontic patients with fixed lingual retainers. Labial gingival recession was assessed on the lower incisors and classified using Cairo's Recession Type system. Clinical parameters were collected, including bleeding on probing, biofilm, brushing habits and oral hygiene behaviours. Logistic regression was used to analyse factors associated with recession.
resultsLabial gingival recession was observed in 27 of 83 patients (32.53%). The mean recession was 0.66 mm. Significant associations were found between gingival recession, age (p = 0.008) and nail/pen/pencil biting habits (p = 0.021). Brushing technique and frequency also showed a significant association.
conclusionsLabial gingival recession was present in one-third of patients with fixed lingual retainers. Age and mechanical habits, such as nail-biting, were significant predictors. Preventive strategies should target behaviour modification and enhanced oral hygiene education.
