[The reimplantation of teeth avulsed by trauma]. / Il reimpianto di denti avulsi per cause traumatiche.

The paper underlines the importance of the reimplantation of teeth following injury in young subjects. The positive results achieved within the short term encourage the extension of this method even to those cases with a poor prognosis (unsuitable means of conservation, long interval between injury and reimplantation). The tooth with in any case serve to retain the space until a prosthetic replacement is inserted when growth has ended.

[The long-term clinical follow-up of a group of patients subjected to surgical intervention for the extraction of supernumerary impacted teeth]. / Controllo clinico a distanza di un gruppo di pazienti sottoposti ad intervento chirurgico per l'estrazione di denti sovrannumerari inclusi.

A long-term clinical control carried out on 34 patients subjected to surgery for the removal of included extra teeth at the Odontostomatological Clinic of the University of Turin is reported. The patients had mostly been treated at ages between 7 and 12 followed up between 4 and 8 years later. Long-term damage, from an orthodontic viewpoint also, is not frequent and when present is not of particular importance. The operation, carried out early and with correct technique, does not cause particular damage to teeth or adjacent bone or nerve structures and does not create psychological traumas for the young patient. It is therefore advisable for the surgical removal of extra included teeth which are causing damage to adjacent structures to be programmed as early as possible so as to permit maximum functional and aesthetic recovery and to minimise to the utmost the consequences of the operation.

[Tumors and the histogenesis of Schwann cells of maxillofacial competence]. / Tumori ed istogenesi dalle cellule di Schwann di competenza maxillo-facciale.

After a brief review of published data relating to the clinical and anatomicopathological characteristics and therapeutic problems of tumours deriving from the nerve sheaths of the oromaxillofacial area, the paper reports 13 cases of these neoplasias observed from 1975 to 1988 in the maxillofacial surgery ward of the Dentistry Clinic at the University of Turin. The group include 6 schwannomas (neurinomas), 6 neurofibromas and 1 malignant schwannoma. Clinical symptoms and methods of diagnosis are described.

[Dental changes in children with malabsorption]. / Alterazioni dentarie nei bambini con malassorbimento.

The paper reviews existing reports on relations between pathologies leading to malabsorption and dental lesion in children. The following dental alterations are reported in the literature: delayed eruption of deciduous teeth, hypoplasia of enamel and dental caries. These lesions have been observed in gastrointestinal pathologies, for example, coeliac disease, chronic diarrhea and recurrent vomiting, intolerance of cow's milk protein, Crohn's disease and salmonellosis. The delayed eruption of deciduous teeth and hypoplasia of the enamel are certainly correlated to malabsorption and maldigestion, especially if these are protracted over time. Dental caries may be due to poor oral hygiene, poor diet and to the presence of modified calcification. Only a comparative study with a control group will enable the effective prevalence to be assessed.
