Conditions

Gingival diseases in patients with thin gingival biotype and treated by orthodontics Oral Health

Interventions

This study is a randomized controlled trial. Patients are randomly selected according to their order of arrival, and the odd numbers are only treated by orthodontics. The even numbers have braces inst

Design outcomes

Primary

Measure	Time frame
1. Acceleration of the orthodontal movement assessed by Little's irregularity index before and every month after the connective tissue graft until the end of the orthodontic treatment 2. Gingival thickness assessed by an endodontic spreader before and after the treatment 3. Width of the attached gingiva assessed by William's prober before and after the treatment	—

Secondary

Measure	Time frame
Gingival parameters measured using the root coverage esthetic score (RES) before and after the treatment: 1. GM (gingival margin): zero points = failure of root coverage (gingival margin apical or equal to the baseline recession); 3 points = partial root coverage; 6 points = complete root cover 2. MTC (marginal tissue contour): zero points = irregular gingival margin (does not follow the CEJ); 1 point = proper marginal contour/scalloped gingival margin (follows the CEJ) 3. STT (soft tissue texture): zero points = scar formation and/or keloid-like appearance; 1 point = absence of scar or keloid formation 4. MGJ (mucogingival junction): zero points = MGJ not aligned with the MGJ of adjacent teeth; 1 point = MGJ aligned with the MGJ of adjacent teeth	—
