A Study of Wedge Operation: clinical evaluation from initial examination to six months after surgery

The purpose of this investigation was to evaluate on the procedure of the wedge operation compared with the full thickness flap operation. The subjects were 27 sites from 10 patients for the wedge operation group and 28 sites from 8 patients for the flap operation group. Before the each operation, the initial preparation as usual routine was taken with plaque control program, including scaling and root planing, every two weeks intervals. Plaque index, gingival index and probing depth were measured from initial examination up to 6 months post-operative. The results were analysed statistically as follows: 1) Plaque indices were shown no signifficant difference between the wedge operation and the flap operation. 2) Gingival indices were shown on the signifficant difference between the wedge operation (15.5%) and the flap operation (49.8%).
