Gingival biotype is a clinical term used to describe the thickness of the gingiva. It has been classified as being thick or thin and may be related to the clinical outcome of root coverage procedures. This study evaluated the impact of gingival biotype on the clinical outcome of root coverage procedures following subepithelial connective tissue graft plus coronally positioned flap. A total of 19 patients, 10 with thin and 9 with thick gingival biotype, were treated for localized Miller Class I or II gingival recessions. After 6 months, 14 patients achieved complete root coverage, 7 from each group. The overall mean pooled root coverage rate was 90.93%. The thin biotype cases yielded a reduced mean root coverage of 88.51% compared with 93.63% for patients who had the thick biotype classification. Although the thin gingival biotype may impair the clinical outcome of root coverage procedures, this limitation does not appear to have a strong influence on the success of the root coverage therapy when subepithelial connective tissue graft was associated with the coronal positioning of the flap.

Microsurgery has evolved, permitting faster vascularization and healing than macro-interventions, reducing tissue trauma and obtaining precise wound closure. Therefore, this study aimed to detail the initial healing steps after the periodontal microsurgical procedure. A -26 year-old female had a localized recession (anterior lower tooth, recession type1-), with the absence of local keratinized tissue width (KTW) and adjacent gingival thickness (GT)<1 mm. After oral prophylaxis and occlusal adjustments, the pink esthetic score was performed (5 points), followed by the microsurgery procedure. Prior to inserting the subepithelial connective tissue graft (SCTG), the epithelial layer was removed, and the root surface was biomodified. Two days postoperatively, it was possible to observe a white layer from the SCTG in the gingival margin, decreasing after 4 days. In 6 days, the sutures were removed; no graft and volume loss was observed. For 9 days, the volume was the maintenance. Nevertheless, there was a reduction in tissue volume in the facial zone. After 11 and 13 days, an improved healing process was found, whereas, after 16 days, it was possible to report stable tissues, which was confirmed after 31 days, with a significant GR reduction and an increase in KTW and GT. Moreover, the final pink esthetic score (PES) was 9. Microsurgery had a faster healing and predictable outcome, suggesting reduced trauma, which may allow a quicker suture removal without jeopardizing the outcomes.
