The purpose of this study is to compare the biometric changes obtained on the recipient site as well as on the donor or control tooth after performing a lateral sliding flap or a coronally repositioned flap with a free gingival graft in order to determine whether the expected results are similar after either procedure.
23 persons with 28 teeth having localized gingival recession. 19 to 68 years old. Areas were randomly selected to either lateral sliding or coronally repositioned flaps. Clinically measurements were at 0, 1, 3, and 6 months.
A mean gain of 2.71 mm of soft tissue coverage resulted after both procedures at 6 mos. This coverage was stable after 1 month. Both the recipient as well as on the donor tooth for all variables tested, including sulcus depth and width of keratinized gingiva were stable after 30 days.
A significant increase in the width of keratinized gingiva occurred on the recipient tooth with both surgical procedures, avg. 3.21 mm at 6 mos.
Significantly more recession occurred post-op on the donor after the lateral sliding flap compared to the coronally repositioned flap.
No significant variations were found in the amount of soft tissue coverage relative to the width and depth of the recession. Repositioned flaps over a denuded root surface depends more on the height of the papillae present pro-op on each side of the defect, and thus, on the size of the bedn that can be prepared there, than on the width and depth of the recession.
Both procedure provided a satisfactory solution in the treatment of localized gingival recession. Similar amount of root coverage is expected from both. But a significantly more recession occurred post-op on the donor after the lateral sliding flap compared to the coronally repositioned flap.
