This work realized thanks to exchange by IFMSA happened at Medical School Praga's invitation, describes two researchs. The first presents the casuistry of scholastic czechoslovak population; the second 87 cases with multiple teeth agenesis observed at Pedodontic's Clinical of Praga's Hospital Motol. The Authors, after describing the review of literature about epidemiology, etiopathogenetic, symptomatology and diagnosis aspects, present a personal contribution in accordance with existing literature.

The coronal fractures of the upper incisors for traumatic injuries represent the 8% of the total dental trauma. The use of new dentinal adhesive have permitted to obtain new interesting development in dental traumatology and dental esthetic, like the possibility of the utilisation of the dental fragment, of the incisor broken for a trauma. The new dentinal adhesive is the Gluma (Bayer). The Authors describe the technique, the times, some particulars and step by step all the method to obtain good final results. Finally are presented all the advantages compared to the traditional methods with the composites materials.

Carious cavities treated with traditional system and with chemo-mechanical system have been compared at Sem. The pulpal biocompatibility and toxicity absence are clinically and radiographically observed and verified on elements subjected to direct and indirect pulpal capped treatment.

Patients affected by acute leukemia under radiotherapy and chemotherapy, less than 12 years old were investigated about DMFT index. Patients were in total remission. All erupted permanent teeth, with attention to an eventual oligodontia of non erupted teeth also, excluding third molars, were investigated by clinical and X-Ray examination. Authors concluded that there is no difference between these patients and normal subjects for this index.

The Authors point out the expedient that support a normal eruption of the teeth when used during secondary dentition avoiding a following orthodontic treatment.

Human teeth morphogenesis was studied by optical microscopy from the 10th to 20th week of fetal life. Enamel, dentin and pulp development were analyzed. An important observation on mandibu teeth arises from this investigation that consists in a biforcation of mandibular ossification in two branches, this could allow to the teeth to develop inside the mandibular arch.

The early morphofunctional reequilibration of skeletal III Class pattern is one of the keys of resolution of this complex and dramatic pathology. Long-term controls suggest the use of Quad-Helix and III Class elastic traction as soon as possible, in order to correct premaxillary and maxillary hypoplasia eventually complicated by a posterior cross-bite. The simplicity of interceptive therapy is inversally proportional to the benefits that could be obtained and which are reliable and stable.

Some particular strategies to face the treatment of fearful children are discussed. The Authors show both psychological and pharmacological techniques (especially conscious sedation with N2O/O2), very useful to know the patient better and to start a good relation with the dentist, avoiding any possible negative reaction as well.

The Authors presented sovrannumeraries (S) teeth in primary dentition, and the pedodontic, surgical and orthodontic problems. Semeiotics signs, and X Ray suggested, are described. All the types of S. teeth are showed: supplementaries, conoides, tuberculates and infundibuliformes. For every type characteristics, problems and surgical timing are described. Tuberculates and infundibuliformes teeth are the most dangerous for the permanent teeth interrupted: eruption delay, dilacerations, impactions, fusion, follicles, diseases, are reported. The direction of the growth of S. teeth must be analyzed. If the direction is external the timing of surgery is very important. Finally the Authors emphasized the role of cooperation of pedodontist, with oral surgeon and orthodontist for to obtain good results.

The Authors made a transversal epidemiological study on 256 children attending the elementary schools in a commune of Siena. The subjects aged between 6 and 11 years have been examined having in view a registration of prevalence of dysgnathia problems in children.
