Different surgical techniques have been used to treat periodontal osseous defects. Periodontists were very full of hope with osseous grafts but the results were disappointing or unpredictable. A best knowledge of the biologics determinants of periodontal healing has lead to the concept of guided regeneration. A case of deep osseous defect of a mandibular incisor was treated by the placement of a Gore Tex membrane. The clinical and radiographic result is satisfactory.

This study presents a detailed example of the examination of the tooth treated by thermal therapy, by infrared thermography and the different manners to show the results of the examination. The results of the work shows: the thermal diffusion into the tooth is similar to the thermal diffusion into an isotropic environment, the fusion heat of the dentine is reached without any damage to the pulp. The study of the tooth treated by the thermal action of the MICRO PLASMA SYSTEM confirms the thérapeutical effects of the thermal treatment without any damage to the pulp.

The diagnosis as well as the therapy of fractured teeth are often a real problem for the general practitioner. Their major etiology is iatrogenic but is sometimes accidental or parafunctional. In order to avoid complications we should as a rule use the least invasive techniques in our therapies. The rapidity and the extent of periodontal destruction induced by these lesions impose a precise diagnosis and in most cases an extraction without any delay.

Inspite of the new technics using composite resin, cast dowel and core is still used to replace lost coronal structure of endodontically treated teeth. Before the core preparation, an X-ray is essential. The metal used for the post and core must be the same as the one used later for the following full crown. Preparation methods must be well established. Acrylic resin or silicone may be used as impression technics.

During a 3 weeks period, an immunotherapy by oral route was applied in patients presenting periodontal diseases (gingivitis and chronic adult periodontitis). This study, double blindly conducted, points out a statistically significative decrease of the main clinical symptoms of periodontal diseases (bleeding, erythema, oedema, pain, suppuration, fetidness) without any other local treatment and shows the interest of such a therapy in addition to the classical local treatments applied to patients presenting periodontal diseases.

Stelligraph, a software program for designing the removable partial denture offers many possibilities in computer assisted technology. The design can be realized on any particular case, based on three different concepts. This software program can also provide on individual, manual and personalized design this offening complete freedom in the conception. This software program is an expert system in removable partial denture by providing the general practitioner with a rational design as well as clinical guidance for oral rehabilitation.

The XVIIth century is the Golden Century of Holland, liberated from spanish domination, and becoming an economical and political powerful State, owing to maritime trade. Art, Science and literature progress and shine as never equaled. Our investigation is based upon writtings of professors, and those of their students or any other practitioner newly established in Holland, land of liberty. In those writings we are in search of remedies against odontology. Usual therapeutics is all together general and local. General, its evacuated peccant humors by vein section and purgation; local, it acts upon surrounding regions (shoulder, tempel, ear, chin), in the mouth (collutorium), on the tooth or its cavity.

It is important to know child bruxism symptomatology and etiology. It will allow diagnosis by simple endo and exo oral examination, in deciduous and mixte denture. Early treatment of bruxism can then be established, preserving integrity of permanent denture.

The calcification of the stylo-hyoid ligament is very often accidentally discovered during a panorex examination. Sometimes it is responsible of lateral and cervical pain spreading to the oral cavity and the maxilla. This anatomic landmark results in man from the more or less complete ossification of the hyo-branchial system due to the persistence of the Reichert cartilage. The anatomical environment of the ossified stylo-hyoid ligament is very rich in thick blood vessels and cranial nerves and can lead after compression or irritation to: vascular pain of the external carotid artery, recurrent syncopes by irritation of the carotid sinus, pain in the tonsils, phonation and swallowing troubles, referred pain in the temporo-mandibular joints. The standard clinical and radiographic examination will help to establish the differential diagnosis. The treatment is either non surgical, by cutaneous infiltration of local anesthetic or surgical, by the removal through the oral cavity of the calcified stylo-hyoid ligament.

Psychogenic oral paresthesia represent a proteiform condition, more and more frequent. The failure to recognize it can lead to unjustified investigations or/and procedures. These manifestations are secondary to a psychic problem which varies in severity. In most cases, the establishment of a trust relationship, explanations to the patient and eventually a psychotherapy are sufficient to eliminate the symptoms. In severe cases, a psychotherapy or a psychiatric treatment are almost always necessary.
