The SLA (sandblasted with large grit and acid etched) surface is a textured surface that has been documented to lead to a rapid and strong implant fixation. The purpose of the present study was to determine the contribution of sandblasting in addition to etching to implant anchorage. It was also aimed to determine if the pits carved during etching alone have a bone-interlocking capacity that leads to microanchorage between the implant and bone. SLA implants and machined-and-acid-etched (MA) implants were placed in the maxilla of Land Race pigs. After 10 weeks of healing, they were reverse torqued. The reverse torque of the SLA and MA implants was 157.29 +/- 38.04 N cm and 105.33 +/- 25.12 N cm, respectively. Sandblasting increased bone anchorage by 49.3%; the difference was statistically significant (p =.028). Bone was found attached to both surfaces; bone ingrowth was found in the pits of both surfaces. It is suggested that the two surfaces are able to generate bone interlocking and mechanical coupling at the interface. When finite-element modeling is performed with these surfaces, it is suggested that the bound mode be used instead of the slip mode.
This case-control study demonstrates that periodontal disease, especially markers such as BOP and bone loss, is independently associated with ischemic stroke.
-Infectious emergencies occupy a very significant part of odontology consultation. So, a retrospective study undertaken in 2003 in a french hospital (Dijon) was down to analyze the distribution of infectious pathologies in odontological emergencies. 352 patients were admitted during 2003 for an infectious dental etiology. The age of patients lies from 4 to 96. The pathology most frequently met is firstly the endodontical abscess and secondly cellulitis. The causal teeth from all confused arcades are first molars. And more surprising is the prevalence of the infectious emergencies on the left side. Regarding the distribution according to the period of the year, a slight prevalence is noticed in summer. This analyse permits to evaluate the various parameters which can influence infectious etiology urgencies.

Les urgences infectieuses occupent une place non négligeable dans les urgences odontologiques. Une étude rétrospective a été menée en 2003 dans un hôpital français (Dijon) afin d'analyser les urgences infectieuses en Odontologie. 352 patients ont été admis en 2003 pour une infection d'origine bucco-dentaire. L'âge des patients allait de 4 ans à 96 ans. La pathologie la plus fréquemment rencontrée est l'abcès endodontique compliqué par une cellulite faciale. Les dents causales à l'origine de ces urgences infectieuses sont le plus souvent les premières molaires. Ces urgences infectieuses prédominaient légèrement du côté gauche et pendant l'été.The odontological emergencies are increasingly frequent with the regional service of reception of emergencies. The dental abscess is a practical and odontological reason for a nearly daily consultation. It presents a very exceptionally vital risk. However, expressing itself in various clinical, unquestionable and specific cases requires an immediate assumption of responsibility by their particularly fugacious gravity, and sometimes involving the vital forecast [1]. The infectious emergencies are very often a complication of pulpar pathology; they occupy a very significant part of the consultation in odontology and touch the various social classes. These dental and periodontal infectious complications which are local (abscess, teeth), regional (let us phlegmons, cellulitis and osteitis) or remote (endocarditis, brain abscess, acute rheumatoid arthritis. . .), sometimes threaten the vital forecast [2].
RÉSUMÉLes lymphomes sont des proliférations malignes intéressant le tissu lymphoïde, représentés principalement par le lymphomes non hodgkiniens (LNH). Le tube digestif avec la cavité buccale constitue le principal site des lymphomes non hodgkiniens extra-ganglionnaires (LNHE) [14] .
