Gingival recession
Conditions
Interventions
Experimental group: 12 smokers with a history of smoking for at least 5 years, with an average daily intake of 10 or more cigarettes per day
with Miller's class II gingival recession, greater than or equal to 2 mm, located in the canine or premolars. Control group: 14 individuals who reported never smoked
with Miller's class II gingival recession, greater than or equal to 2 mm, located in the canine or premolars.
The gingival recessions of the test (smoking) and control groups (nonsmokers) were treated

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Root coverage percentage calculated after 6 months of postoperative follow-up according to the following formula: 100- (Recession height at the end) X 100 / (Recession height at the beginning); The measurement was performed with the use of a digital caliper | — |
Secondary
| Measure | Time frame |
|---|---|
| Clinical attachment level measured in millimeters 28 days after initial preparation and 6 months after root covering surgery; Measurement performed using a millimeter periodontal probe ;Depth of probing measured in millimeters 28 days after the initial preparation and 6 months after the radicular covering surgery; Measurement performed using a millimeter periodontal probe ;Gingival recession height measured in millimeters 28 days after initial preparation and 6 months after root rcovering surgery; Measurement performed with the use of a digital caliper ;Gingival recession width measured in millimeters 28 days after initial preparation and 6 months after root covering surgery; Measurement performed with the use of a digital caliper ;Keratinized mucosal height measured in millimeters 28 days after the initial preparation and 6 months after the radicular covering surgery; Measurement performed with the use of a digital caliper after pigmentation of the mucogingival line with Schiller's solution ;Keratinized mucosal thickness measured in millimeters 28 days after the initial preparation and 6 months after the radicular covering surgery; Measurement performed using an endodontic duster and rubber stop;The set was inserted into the gingiva 2mm apical to the gingival margin, until the buccal bone plate, when the rubber stop was positioned making slight contact with the gingiva; The distance between the tip os the endodôntico duster and the rubber stop was then measured using the digital caliper ;Complete root coverage percentage was obtained from the percentage of cases with 100% of root coverage (no root exposure) ;Satisfaction with aesthetic result assessed from a questionnaire delivered to the patients at the end of the study (6 months after surgery) ;Postoperative morbidity assessed from a pain scale delivered to patients at the end of surgery; They were instructed to note, if they needed to use analgesic medication for postoperative pain, the time of | — |
