Abstract :
[en] Aim: The objective of this study was to compare two different periodontal plastic surgery procedures to treat Miller’s class I recession: a coronally advanced flap (control group) versus the pouch technique (test group), both of which were associated with connective tissue graft.
Methods: Forty consecutive patients were included, with 20 patients being allocated for each group. The level of recession coverage, the keratinised tissue quantity, gingival aesthetics (PES), and postoperative outcomes were assessed for a follow-up period of 6 months.
Results: After 6 months, both techniques allowed for the excellent mean root coverage of 96.3 ± 12.1% in the control group and of 91.3 ± 17.6% in the test group. Complete root coverage was achieved in 89.5% (17/19) and 79% (15/19) of the recession cases in the control and the test groups, respectively. A significant increase in keratinised tissue height (p=0.0011) was observed in the test group. A significant improvement in the pink aesthetic score was found in the 2 groups, but gingival texture displayed significantly better results in the test group (p<0.0001). No significant difference between the 2 groups was found in terms of the morbidity outcomes. Pain killer consumption was similar in the 2 groups and significantly decreased over time.
