ABSTRACT
OBJECTIVE: The Shprintzen-Goldberg syndrome is an extremely rare syndrome with a characteristic face. This is one of a group of disorders characterized by craniosynostosis and marfanoid features. The aim of this study was to present a new sporadic case of the syndrome and describe in detail the findings at the maxillofacial region.

PURPOSE: General consensus has been reached on extracting mandibular third molars when they are involved in pathologic processes. However, early extraction is advisable in cases of eruption disturbances of the mandibular second molar, before or during orthodontic treatment. METHODS: Thirty-two patients with early extraction of the mandibular third molar before or during orthodontic treatment were examined. RESULTS: In these cases either the presence of the third molar presented an obstacle in the eruption path of the second, or third molar germ removal was considered beneficial to the course of orthodontic treatment. CONCLUSIONS: Early extraction of the mandibular third molar facilitates the eruption of the second molar, especially in cases where evidence of crowding and lack of space in the posterior mandibular region exist. Orthodontic treatment may, in some cases, aggravate eruption disturbances of the second molar.

Submersion occurs when a previously erupted tooth becomes embedded in the oral tissues. The purpose of this paper is to examine the distribution, the degree of re-impaction, the rate of congenital absence of the successor buds and the treatment in 28 submerged teeth in 17 patients.

In this paper the essential knowledge for the overall tracing of the postero--anterior cephalometric radiographs has been discussed. Special attention has been paid to the structures of the facial skeleton and their radiographic description as well as to the methodology of an effective tracing. This knowledge could be very useful to a better study of the postero--anterior radiograph which helps to a complete diagnosis.
