We present a prospective clinical study on use of tranexamic acid mouthwashes in patients taking oral anticoagulants and who have to undergo minor ambulatory oral surgery, without modifying their anticoagulant therapy.Forty patients (18 men and 22 females) aged from 42 to 81 were studied from April 2000 to December 2002. All patients were under the same anticoagulant, vitamin K antagonist, (Sintrom) for different pathologies. The anticoagulant therapy was not modified neither before nor after surgery. More than 70 oral procedures were carried out under local anesthesia. The International Normalized Ratio of prothrombin time (INR) was=4. Tranexamic acid 5% (Exacyl) mouthwashes were prescribed during and after surgery.All the patients were followed up during 2 weeks after surgery. There were no postoperative bleedings.Use of tranexamic acid mouthwashes under a specific protocol is an efficient, reliable and economic method in preventing postoperative bleeding in patients under oral anticoagulant therapy.

The soft tissue response to clinically retrieved and decontaminated cover screws was evaluated in a rat model. The cover screws were cleaned by using citric acid, sterile water, hydrogen peroxide and CO2 laser alone or with a combination of these. In addition, decontaminated but not cleaned and unused cover screws were used as negative and positive controls, respectively. After cleaning the cover screws were implanted in the abdominal wall of the rat for 6 weeks. The thickness of the fibrous capsule and the number of macrophages within the capsule were measured by means of light microscopical morphometry. As compared to the negative control, CO2 laser on dry surface, CO2 laser + hydrogen peroxide and the positive control had statistically significant thinner fibrous capsules. As compared to the positive, only laser alone resulted in a similar tissue response. It is concluded that CO2 laser used alone or in combination with hydrogen peroxide may be used clinically for sufficient decontamination of titanium surfaces.

The aim of this study is to observe the frequency of the different types of disc displacements (d.d.) of the TMJ (ATM) and to evaluate if these types are related or not with malocclusions. One hundred patients and 13 asymtomatic volunteers underwent full clinic examination. sagittal MRI (mouth open and closed) and coronal MRI (mouth closed). The different types of disc displacements were noted and cumulated in frequency and in relation with several occlusal criteria. Unlike the general opinion stating that the antero-medial d.d. (d.d. a-m) are the most frequent amongst the internal derangements, the result of this study reveals that the antero-lateral d.d. (d.d. a-l) are more frequent amongst the patients (35.1%) and the asymptomatic volunteers in general and particularly in view of a malocclusion (exagerated anterior overlapping and posterior cross bite). The study gives rise to the question of the etiology of a antero-lateral d.d. and sets back the hypothesis of the lateral pterygoid muscle fundamental role in the disc displacements.

The authors describe the Meige's Syndrome also known as blepharospasm or mandibulo-oral dystonia. This Syndrome rather known by Neurologists and Ophthalmologists than by Stomatologists actually benefits by a specific treatment based on botulin toxins.

The use of a new alloplastic biodegradable implant called BIOFIX made of polyglycolate is described. We used it to cover bone defects in maxillo-facial surgery, principally for orbital floor restoration and frontal sinus repair, with very good results. It is an excellent material of temporary support and guidance during the healing period and new bone formation. However, it will be necessary to wait for the results of a multicentric european study to confirm its superiority in maxillofacial surgery.

The first and second branchial arch syndrome is a congenital affection, among whom one can range as well hereditary as non-hereditary entities. They always cause a badly mutilating facial asymmetry. In this article, the first and second branchial arch syndrome were divided in hemifacial and bilateral dysostoses. We pointed out the hemifacial microsomia, the most occurring entity in these series. From two case reports, we attempt to give a treatment synopsis of this syndrome, which is always done by a multi-disciplinary team, including dentists, orthodontists, maxillofacial surgeons and plastic surgeons.
