1 · What the graph read from it

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.

Abstract

backgroundThe effectiveness of the modified coronally advanced tunnel (MCAT) technique in treating isolated gingival recession Type 1 (RT1) has been evaluated in a few studies. Hence, this prospective randomized controlled clinical trial was directed to assess the MCAT technique with connective tissue graft (CTG) or collagen matrix (CM) in improving clinical outcomes for isolated gingival recession type 1 (RT1), mainly the attached gingiva width (AGW) as a primary outcome. Despite the clinical relevance of AGW, there is a gap in the literature with limited studies concerning it as a primary outcome.

methodsForty patients were chosen and randomly assigned into either the control group (MCAT and CTG) or the test group (MCAT and CM) for short-term assessment (6 months) of single (RT1) gingival recession treatment. The primary outcomes were attached gingiva width (AGW), recession depth (RD), recession width (RW), and mean root coverage% (MRC%). The secondary outcomes included gingival thickness (GT), keratinized tissue width (KTW), periodontal probing depth (PPD), clinical attachment level (CAL), plaque index (PI), gingival index (GI), pink esthetic score (PES), root coverage esthetic score (RES), and patient-reported outcome measures (PROMs). The chi-square (χ²) test, Mann-Whitney U test, t-test, and Friedman test were used for statistical analysis of the outcomes.

resultsForty patients aged 18 to 45 years were enrolled in the current study. Evaluation of the primary outcomes (AGW, RD, RW) showed significant differences in the studied groups from the baseline to the final follow-up period (p-value ≤ 0.05). The MRC % results showed significant improvement after the 6-month follow-up period. For the control group, the MRC% was 97.08 ± 9.09, while for the test group, the MRC% was 96.75 ± 7.99. The PI, GI, PPD, CAL, KTW, PES, or RES values did not significantly differ among the two groups from the baseline to the final follow-up period.

conclusionOur study supported the efficacy of the MCAT in isolated gingival recession coverage. The CM may act as an alternative to CTG by increasing the patient's satisfaction and reducing tissue morbidity and surgical time.

trial registrationThe current clinical trial was retrospectively registered in ClinicalTrials.gov (ID: NCT06065774) and released on 11/18/2024.
