The control of haemorrhage at the operative site during periradicular surgery

Clinical technique Effective apical sealing in endodontic surgery requires a dry root-end cavity to insert the filling material. A number of procedure s for controlling haemorrhage have been described in the literature. An imp rovement of these techniques is proposed in this paper: by using a mixture of surgical wax and fibres of calcium alginate. This device, easy to place, sterile and non-toxic, permits placement of a root-end filling under more favourable conditions.
