RESUMEN
Review of literature regarding frequency of traumatic injuries of primary teeth, types of injuries, therapy and possible consequences in permanent dentition. The diagram of prevalence shows no direct correlation to age, whereas according to diagram of incidence 70% of injuries occur in the second and third years of life. Injuries without dislocation of the deciduous tooth: fractura coronae dentis decidui, contusio seu concussio dentis decidui, fractura radicis decidui. Injuries with dislocation: luxatio totalis dentis decidui, luxatio partialis dentis decidui, intrusio dentis decidui. Consequences of traumas can be detected in disturbances of second dentition, in developmental anomalies of enamel and in considerable deformities of homologous permanent tooth.

An analysis of 191 primary incisors damaged by acute mechanical trauma on 108 children, ranging in age from 2 to 6 years, has showed that most of the patients were between 2 and 3 years of age (67%) when the accidents occurred. According to this clinical study the most frequent type of injury was partial luxation (42.93%). In 53.7% of cases the accident involved two teeth. The upper central primary incisors were damaged most frequently (82%). The ratio of boys to girls was 3:2.

Based on a study of ten deciduous human teeth, (front teeth and molars) under a Scanning Electron Microscope type Tesla BS 300 we could observe that the differences of the mineralization levels are more striking in the peritubular dentin, then in the intertubular structures. The structural transformation increases by approaching the resorption surface. Near the enamel the resorption surface shows a two-edged demineralization. The mineralized part near the enamel is probably the result of the protecting processes of the human organism.

The second dentition is a process determined in space and time which presumes the presence of the permanent dental germ, its optimal position and the soundness of the periapical area. In absence of these conditions the clinically and histologically proved pathological phenomena (ex. the pathological triad of second dentition) can occur.

The four directional (right nourishment, mouth hygiene, fluorides, early treatment) complex Infant Dentistry prevention and its teaching viewpoints are summarized. It is emphasized that no order of importance must be made among the four directions since lasting success can be achieved only by consequent carrying out of all tasks.

In twelve patients aged 13 to 24, histological examinations of twenty persistent milk teeth (with persistency having been due to aplasia of permanent teeth) showed that root resorptions are possible in such cases too. Cellular resorption results in the root being decomposed lacunally or linerly, respectively. The formation of osteodentin, which is a result of the phase of apposition and which is taking place in the pulp and along the surface of resorption, respectively, is considered a characteristic concomitant phenomenon. However, this tissue does not cause "true ankylosis". Accordingly, use of the term "ankylosis" to describe such cases is questionable. The author, on the strength of the results obtained in these studies, believes that root resorption of persistent milk teeth is a pathological process in the case of congenital absence of permanent teeth.

A total of 4106 children aged 2 to 18 were examined roentgenologically, with intraoral roentgenograms of the molar region being made on 148 (3,6%) of them. Analysis of such roentgenograms allows to make conclusions as to the necessity for making roentgen diagnoses on children.
