ABSTRACT
The aim of this investigation was to study the incidence of the appearance of the nutrient canals in the mandibular anterior region of periapical radiographs of patients with diabetes mellitus. A total of 133 patients were examined, 73 patients exhibited diabetes mellitus, where 60 patients did not. The results of this investigation showed that: 1. The incidence of the appearance of the nutrient canals is much greater in the patients with diabetes mellitus (75.34%) than in the patients were used as control (41.66%). 2. In patients with diabetes mellitus, nutrient canals are seen more frequent in males (54.52%) than in females (45.48%). 3. The number of nutrient canals seems to have relation with the duration of disease and the recent value of blood glucose.

The aim of this study was to investigate the existence of asymmetry or not between the right and left side of the mandible. Three hundred eighty six edentulous dry mandibles were measured. The results showed that: --Asymmetry was found in a percentage of 82.26% between the two rami of the mandible, with the right ramus being smaller than the left (45.66%). --Asymmetry was found in a percentage of 82% between the two parts of the body of the mandible, with the right part being smaller than the left (51.91%). --Asymmetry was found in a percentage of 82.2% between the two sides of the mandible, with the right side being smaller than the left (47.4%). --Asymmetry was found in a percentage of 82.2% between the two sides of the arch, formed of the rounded lower border of the mandible, with the right side being smaller than the left (49.2%).

Eagle's syndrome has received scant attention in both medical and dental literature. The symptoms related to this condition can be confused with those attributed to a wide variety of facial neuralgias. The present case refers to a 46-year-old white woman with the symptomatology of Eagle's syndrome, especially the carotid artery type.

The purpose of this study was to determine the incidence of the appearance of nutrient canals in periapical radiographs of the mandibular anterior region of hypertensive patients with alveolar bone loss. A total of 220 patients were examined, 120 patients exhibited hypertension and radiographic signs of alveolar bone loss, where 100 patients did not. The results of the present study showed that: 1. The incidence of the appearance of the nutrient canals is much greater in the hypertensive patients with alveolar bone loss (58.33%) than in the nonhypertensive patients without alveolar bone loss (54%). 2. In hypertensive patients with alveolar bone loss, nutrient canals are seen more frequent in females (59.01%) than in males (57.62%). 3. The number of nutrient canals increases with severity of alveolar bone loss.

Although the orthopantomograph has some disadvantages comparing with other techniques in the study of the TMJ, is useful sometimes for visualization of extensive osseous changes of the condyles. This study was done in order to study the exact site of the radiographic representation of the condylar surfaces in the orthopantomograph and to evaluate the degree of alteration of their size and shape. In two dry skulls (one edentulous and the other with complete dentition) a lead foil was placed in each one of the five surfaces of the condyles. The orthopantomographs were taken and the site of the radiopaque lead foil was evaluated for the radiographic representation of each surface. Also the degree of the alteration of the size and shape of the condylar surfaces was determined by the calculation of the two dimensions of each surface, in the skull and in the radiograph. The results of this study showed that all five condylar surfaces are contributing for the radiographic image of the condyle and always in an exact position each of them. The greatest distortion of the size and shape is taken place in the upper surface of the condyle and finally that the orthopantomograph cannot give us exact and accurate representation of the shape or the morphology of the condyle.

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.

In the present study the degree of density of three anatomic regions in 215 orthopantomographs was evaluated. The three anatomic regions which were selected were: the maxillary sinus, the hard palate and the hard tissues (enamel and dentin) of the right lower first molar. The degree of density was correlated with the age and sex of the patients and it was found to increase with the age. The difference of the density was found to be statistical significant between the decade 1-10 compared to the other decades of age. The degree of density was greater in the women in all three anatomic regions but statistical significant only in the first molar region and in the decades 1-10 and 31-40.
