This article reports a case of atypical tetanus localised exclusively in the head, with an oral point of entry very rare nowadays. With reference to this case, we describe the pathophysiology, clinical forms and the treatment of this infection. It is therefore essential that every practitioner, in the presence of a trismus, should consider the possibility of tetanus.

Since the use of cyclosporine A therapy in kidney, cardiac hepatitis livers pancrease transplants, the oral surgeon have seen gingival overgrowth under this immunosuppressive drug. In this article the authors reports 2 cases and accomplishes light and electron microscopic study. Gingivectomy is exposed.

A thorough clinical examination will help determine a precise diagnosis and a treatment plan in accordance with our patients expectations. A good prognosis will depend upon the strict observation of the rules regulating conventional endodontic and surgical treatments.

340 adult diabetics participated to this work in Conception's Hospital of Marseille. The examinated teeth were the 16, 21, 24, 36, 41 and 44. The indexes (Pl.I., G.I.), the depths of the pockets (upon these teeth), the quantity of gingival fluid (upon 21 and 24 only) were registrated. Statistically, the results showed: the gingival inflammation, the quantity of plaque and the severity of the periodontal disease increase with age and that with a maximum between 55 and 65 years.

The future site of the implant, close anatomical obstacles and the insertion axis of single various implants, can be determined by the use of the scanner. Giving precise instructions is very important in determining the selection of sectional planes to be used the radiologist such as: axial sections, direct or reconstructed frontal sections, sagittal or reconstructed sagittal oblique sections. Precise measures can be directly realized on the scanner. When it is impossible to obtain the orthogonality of all the sectional planes, correction of the measures can be realized by using the cosinus of the angle obtained by the effective sectional plane and the ideal plane.

This article is about the different iatrogenic (or others) mechanical and/or chemical trauma that can affect the mandibular nerve and which can lead to paresthesia. Depending on the different causes of the paresthesia, the prognosis for nerve sensitivity regeneration will vary: In some cases treatment is necessary to make the symptoms disappear, in others expectation will be the rull and the prognosis is very poor.

The chemical principles of tooth bleaching are detailed in order to analyze scanning microscopy data obtained following internal and external bleaching tooth bleaching appears harmless to the enamel structure providing no etching is applied prior to bleaching. Previous enamel undermining appears to increase the porosity along preexisting cracks. Internal bleaching gives way to enamel and dentinal demineralization, which is of particular importance at the dento enamel junction. The biological effects of bleaching on dental hard tissues must be viewed in light of the clinical indications for these procedures.

Oral cancers are frequent among men aged 45-60. They are detected by dentists stomatologists and general practitioners, at advanced stages with cervical metastasis node. The routine oral examination and detection of a precancerous lesion or an early cancer for alcohol drinkers are tobacco smokers. Main cancer symptoms are presented there to support diagnosis.

The bacteria of the genre Capnocytophaga are part of the subdominant flora of the oral cavity. For diverse microorganisms it has been proved that the adhesion constitutes the first step of the colonization of a place leading to the eventual pathology. The adhesion capacity to human epithelial cells (keratinised and non) of eight strains of genus Capnocytophaga has been studied. All strains appear to have a very weak capacity of adhesion. This diministe can be originated from the fact that the host cells have been harvested from healthy subjects.

Actually, the CANAL FINDER SYSTEM is the only entirely automated endodontic device. After four years of existence, many evaluations were able to show the qualities of this system regarding root canal penetration, cleaning and shaping. The earlier concerns such as ergonomical problems were solved: automated extraction of the K-file, automated sodium hypochlorite irrigation. A new file was created, particularly well adapted to the root canal shaping of curved canals. This addition has improved the efficiency of the automated instrumentation. The CANAL FINDER SYSTEM has reached a maturity level permitting an excellent reliability and ease of use.
