Many authors have advocated different methods of treating alveolar osteitis. Despite many years of research, however, little progress has been made and so a study with large enough sample and standard outcome measures is warranted.

Goal of this study is assess the effect of postoperative use of a monoject syringe on postoperative complaints after surgical removal of a lower third molar.

One of the most common postoperative complications after the removal of a third molar is a condition known as dry socket. This term has been in use since 1896. Since then several other terms have been used, including alveolar osteitis, postoperative alveolitis, alveolitis, sicca dolorosa and fibriniolytic alveolitis. Bim labelled the complication fibrinolytic alveolitis which is the most accurate of the terms, but also the least used. The condition has generally been characterised by delayed healing associated with degradadtion of clot, and is usually accompanied by persistent, radiating, pain postoperativively in and around the extraction site that is not easily relieved by analgesics. Because of the pain, swelling and trismus, patients also tend to have a greater need for painkillers. If it is possible to reduce the amount and severity of postoperative pain felt by patients the postoperative period would be more endurable, the quality of life will be less affected, and in addition to this it is possible that the amount of analgesics taken by patients after surgery could be lowered7. It can be a burden for both patients an surgeons and my result in a loss of productivity because at least 45% of patients require multiple visits to the surgeon.
