[Treatment of superior incisor gemination]. / Traitement d'une gémination incisive supérieure.

An 11 year old child presented to our department with an isolated abnormality of the left superior median incisor which was bigeminate. The existence of two distinct roots allowed the separation of 21 and 21 b with extraction of 21 b and preservation of 21, whose crown was reconstituted by means of a composite. There was a favourable outcome with conservation of the vitality of the tooth and no signs of ankylosis.

[Statistical study of alveolar process inclination. Analysis of results of teleradiographic examinations of the head, in sagittal and vertical projection, in 1 600 children referred for consultation in a specialised dentofacial orthopedic unit (author's transl)]. / Etude statistique de l'inclinaison des procés alvéolaires. Analyse des téléradiographies de la tête en incidences sagittale et verticale de 1 600 enfants adressés à une consultation spécialisée d'orthopédie dento-faciale.

For 1 600 children sent to a dental facial orthopedics consultation, the vestibulo lingual inclination of the incisors and molars was measured on two cephalograms of the head, the first one in profile, the second in vertical incidence, the X-Rays being perpendicular to the plane of the biting surfaces of the molar teeth. A statistical analysis was realized on the dental inclination previously observed in order to precise the frequency and amplitude of each anomaly, test their associations and evoke their muscular causes.
