Eligibility
Inclusion criteria
Inclusion criteria: Patients who present Cairo RT1 gingival recession; the teeth must be healthy, with all sites presenting a probing depth less than or equal to 3 mm; bleeding rate less than or equal to 5%; without gingival inflammation; free of caries; both sexes

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Expected outcome 1 (Primary): It is expected to observe statistically significant differences between the groups in the structural parameters of gingival recession, including recession height, width, gingival thickness, and attached gingiva height, measured using standardized methods. ;Observed outcome 1 (Primary): Significant improvement was observed in all structural parameters in both groups, with statistically significant differences favoring the group treated with Ozonated Platelet-Rich Fibrin associated with coronally advanced flap compared to the control group. ;Expected outcome 2 (Primary): Significant improvement is expected in periodontal health parameters, such as probing depth and clinical attachment level, after treatment in both groups. ;Observed outcome 2 (Primary): Both groups showed a reduction in probing depth and an improvement in clinical attachment level, with no statistically significant difference between them. ;Expected outcome 3 (Primary): A reduction in pre- and postoperative dentinal sensitivity is expected, measured by the modified U.S. Public Health Service index, in both groups. ;Observed outcome 3 (Primary): The group treated with Ozonated Platelet-Rich Fibrin showed a significantly greater reduction in dentinal sensitivity compared to the control group. | — |
Secondary
| Measure | Time frame |
|---|---|
| Expected outcome 4 (Secondary): It is expected to identify and classify each patient’s periodontal biotype, correlating it with the clinical outcomes obtained.;Observed outcome 4 (Secondary): The periodontal biotype was successfully classified, but no significant association was found between biotype and the clinical outcomes evaluated. | — |
