In this study an attempt was made to correlate the causative factors of leukoplakia. Histologic criteria helped for the classification of our cases in three groups according to widely accepted standards. As final result it is that smoking and excess use of alcoholic drinks could be involved as causative agents. The clinical appearance of the leukoplakia lesions with their histological type is also correlated.

285 patients complain for pain in the oral mucosa. 92 patients characterized the pain as causalgia. The informations from the history taken were estimated by Bayes' formula. The results from this study showed there is possibility to be causalgia the pain in the oral mucosa characterized as burning, smarting or both of them.

After a short review of the recent literature on headache the close relationship between headache and craniomandibular disorders was studied. In a total of 116 patients with craniomandibular disorders in the Stomatognathic Physiology Clinic of the Dental School of the University of Athens, 73 patients (62.9%) were found suffering from headache. In most of the patients the headache subsided after the treatment.

The success of a prosthesis, in the past was related only to the perfectness of construction and the occlusion. Nowadays the criterion for the acceptance of a prosthesis is its good relation to the gingival tissues. It would be a great error to isolate some parts of the prosthesis and study their possible influence to the gingival tissues. Instead of this, prosthesis should be seen on its whole. The proceeding for the prevention of the periodontal damage is related to all the stages of the construction of a prosthesis beginning from the tooth preparation, the impression till the fixation of the temporary prosthesis. According to these, the present study deals with the elements of the prosthesis which may affect the gingival tissues.

The apicoectomy in molars is a well accepted, though not so popular, method for the treatment of molars with chronic inflammatory periapical disease. This paper is about the indications as well as the surgical technique of the operation. The procedure is connected with very good clinical results and no serious complications, therefore is suggested for wider clinical application.

In this paper a retrospective clinicostatistical study of 508 cases of odontogenic cysts of the jaws treated at the Department of Oral and Maxillofacial Surgery of the University of Athens during the last ten years 1977-1987 is undertaken, in order to evaluate their frequency and other aspects of clinical and therapeutic interest. These 508 odontogenic cysts represent 78.7% of the total number of cysts of the jaws treated in the same period in our department which means that the frequency of odontogenic cysts is still high. In regards to the incidence of each variety of odontogenic cysts, radicular cysts were found to have the highest frequency (59.6%), followed by the residual cysts (28.4%) and dentigerous cysts (12%). A higher incidence of odontogenic cysts in males (65.3%) than in females was also found, a fact which accords with that of other authors. The age distribution for patients with radicular cysts was the 3rd decade, for patients with residuals cysts the 6th decade and for patients with dentigerous cysts the 2nd decade. The majority of radicular and residual cysts was located in the maxilla whereas dentigerous cysts were more frequently located in the third molar mandibular area. Intraoral painless swelling was the most important clinical finding (74.6%). Radiologically the most frequent finding was that of a radiolucent area surrounded in 96.2% of our cases by a continuous radiopaque line. All these lesions were treated either by enucleation and apicoectomy of the teeth or by enucleation and extraction of the teeth followed by primary closure of the surgical cavity. In two cases of dentigerous cysts a two stage operation was performed. The results were highly satisfactory.

The aim of this study was to determine the incidence of fainting during the procedure of a simple extraction in healthy individuals and the probable difference in its incidence and expression in relation to sex and age. Nine hundred eighty-nine healthy patients were examined (491 men and 498 women). From our results it was concluded that the incidence of fainting during a simple extraction is extremely low. It was not found statistical significance between faint and it's relation to sex and age.

This study deals with the relationship which exists between upper and lower anterior teeth. Measurements for the width of the upper central incisor, six upper anterior teeth and the six lower anterior teeth were drawn from 98 couple of casts taken from 50 female and 48 male age range 22-27 years old. Our results showed: A) A significant statistical difference exists between male and female regarding the width of upper and lower anterior teeth. B) There is no a statistical significant difference between these two groups regarding the width of the upper central incisor. C) There exists a relationship of 1.3 between upper and lower teeth. D) A relationship of 6.1 between upper anterior teeth to central upper incisor. E) A relationship of 4.7 between lower anterior teeth to upper central incisor.

Occlusal splints have been very often used in dentistry as a treatment modality for patients with craniomandibular disorders. They can be built directly in the mouth or indirectly in the laboratory. The purpose of this study was to present an indirect method for the construction of the stabilisation splint. The casts were mounted on a semi-adjustable Whip-mix articulator with face bow. After waxing up, the splint model was adjusted in respect to the desired occlusal contacts, in centric relation. The splint model was converted to acrylic using the method as for the construction of dentures and was finally adjusted in the mouth.

In our investigation we have studied and analysed the modifications on the ultrastructure of the cocci and bacteridium of saliva under "in vitro" influence of sparse and dense solutions chlorhexidine di-gluconate. We noticed that the sparse solutions of the drug revealed ruptures of the cellular wall and of the cellular membrane as well as "plasmoptysis" and "plasmolysis". The protoplasm, showing a general coagulation, damage of the cytoplasmic membrane and the cellular wall and in concentrations of 1% and 2% we observed a disorganisation of the nuclear chromatin.
