[Study of the etiologic factors of bucco-dental pathology in handicapped children and adolescents].

Periodontal diseases and dental caries are extremely frequent in children and adolescents with sensori-motor handicaps. This study was undertaken to identify etiological factors of these affections in order to define preventive measures. During a 3-year-period, a survey was performed among 994 handicapped children and adolescents from 14 institutional centres of the Rhône-Alpes Region. Factors appearing significantly involved in the etiology of periodontal diseases and dental caries among this population were insufficient brushing, lack of motivation towards oral hygiene of the institution, is staff the severity of the motor handicap, and long-term treatments with psychopharmaceutical agents. The authors suggest that preventive measures should be taken in order to eliminate these disabling dental diseases in handicapped children, mainly a reduction in sugar intake, a motivation of the staff to enforce oral hygiene and a limitation of psychopharmoceutical treatments.

Dentinogenesis imperfecta with dens in dente.

An uncommon case of dentinogenesis imperfecta with dens in dente was studied by light microscopy, microradiography, and electron-microprobe analysis. Numerous canals and cellular inclusions were found in the coronal portion of the dentin where the tubules were sparse and irregularly distributed. In the radicular portion of the molar, large canals ran parallel to each other down to the apical region. The cementum was thinner and the Tomes granular layer greater in amount than usual. A dens in dente occurred in the radicular portion of the molar. It was located in a cavity and consisted of a mineralized cap of enamel, a spherical dentinal mass, and cellular cementum, located outside the cavity and in the "cervical" portion of the dens in dente.
