Kneckt, Mirka, Psychological features characterizing oral health behavior, diabetes self-care and health status among IDDM patients Abstract Associations have been found between diabetes status and periodontal diseases and dental caries. In addition to biological explanations, psychological features can be proposed to affect the relations between oral health and IDDM (=insulin-dependent diabetes mellitus). The aim of this study was to evaluate the psychological features characterizing oral hygiene practices, dental visiting and diabetes self-care. The research population consisted of 149 IDDM patients, and cross-sectional data were collected by a quantitative questionnaire, in clinical examinations and from patient records. There was a positive correlation between the sum scores for dental self-efficacy and diabetes self-efficacy and, correspondingly, between the dental and diabetes locus of control beliefs. High self-esteem was found to associate with good adherence to some specific health behaviors, such as tooth brushing, exercising and insulin adjustment. When Weiner´s attribution theory was used, there were similarities in the causal thinking in oral and diabetes view. All in all, especially the perception of self-efficacy was found to be a powerful feature characterizing health behavior. There were overlapping relations showing an association of high dental self-efficacy with good diabetes adherence, of high diabetes self-efficacy with frequent dental visiting, and of good metabolic control with high tooth brushing self-efficacy, frequent tooth brushing and low plaque level. On the basis of these results, enhancement of self-efficacy appears important. These results suggest that there might, indeed, be some common psychological features for both oral health behavior and diabetes self-care. These could partly explain the relations between diabetes status and periodontal diseases and dental caries. The results can be utilized in patient-centered health education by identifying and enhancing the psychological features that characterize health behavior and health status. The results emphasize the need for cooperation between dental and diabetes health care professionals in their daily practice.

The regional odontodysplasia, also referred as odontogenic dysplasia, is a rare condition which has been described as an alteration of the dental development affecting the mineralized structures of both the permanent and deciduous teeth, and it has been associated with retardation in the eruption of the affected teeth, gum edema, hydrocephalus and Epidermal Nevus Syndrome. The etiology is still unknown, however, some hypotheses have been suggested about their origin. About its incidence, this disease is more frequent in the anterior segment of the maxilla and usually unilateral. Epidemiologically this disease shows no predilection for any racial group, being more frequent in the first and second decade of life and predominantly in females. Clinically the Odontodysplasia Regional is characterized as an hypoplasia of enamel and dentin in teeth badly formed with size alteration and form coloration varying of the yellow to chestnut; the presence of smooth and extremely friable dentine, tooth mobility and defective mineralization increases the possibilities of the pulp exposure and a tendency to develop abscesses. Radiographically has the appearance of ghosts tooth with a bizarre morphology; reduction of the normal radiopacity decrease of the thickness of the dentine and enamel structures. They generally present with open apexes; shortened or absent roots; diffuse calcification in the inside of the pulp. Histopathologically it presents with accented reduction of the amount of dentin, presence of great interglobular dentine areas and irregular standard of the dentine canals. Enamel is usually thin, hypoplasic and hypocalcified. The pulp presents atrophic areas, fibrose and hyalinization and the cement does not have marked structural alterations. The treatment of the Regional odontodysplasia has been the reason of many quarrels. This present essay aims to review the literature and report a clinical case.
