Use of ferric-sulphate gel for bleeding control in surgical exposure of impacted canines

The aim of the present study was to compare the influence of bleeding control, with or without using gel hydrosoluble with a basis of ferric-sulphate on the duration of closed- eruption surgery of palatally impacted canines. N=20 patients with unilateral palatally impacted maxillary canines were included in this study Subjects were randomly assigned to two experimental groups: in Group A (N=10) ferric sulphate gel was used before etching enamel surface, in Group B (N=10) conventional technique was applied. The duration of the complete surgery and the duration of the bonding procedure (partial surgery) were measured; moreover the presence or absence of bleeding was assessed at T0 (before etching the enamel surface) and at T1 (after the application of the bonding). The mean of the complete and partial surgical duration were for Group A (33.3±2.8min and 6.02±1.05min) and for Group B (36.7±2.6min and 8.4±2.3min). This difference was statistically significant (P
