[The evolutionary historical (phylogenetic) background of the wisdom-tooth problem].

The almost ubiquitous wisdom tooth problem of modern man is in the present paper made the object of an analysis and evaluation on a comprehensive biological basis. It is pointed out that a number of fundamental traits of human cranio-facial evolution have implied developmental trends which have ultimately placed them at the bottom of the later wisdom tooth problem. These aspects are particularly associated with the discrepancy between the size of the jaws and the dental apparatus, arising by failing coordination in the tempo of regression of the separate masticatory elements during the phylogenetic process. The wisdom tooth problem, however, has not become manifest and acute until the present age, with the marked reduction of masticatory function which has taken place.

[Idiopathic histiocytosis of the jaw].

Principal features of Idiopathic Histiocytosis (IH) are discussed in relation to five cases treated in the Department of Maxillofacial Surgery VMA. Clinical symptoms of the disease are known. Radiology of the bones and bone scintiscans are of most importance for evaluation of extension of the disease. Surgery is treatment of choice. The major problem with IH in the jaws is, however, progressive mutilation of dental apparatus.

Myxoma of the jaws with an unusual intracellular banded structure.

Myxoma of the jaw is a rare odontogenic tumor, probably derived from the dental apparatus. The case described here was studied by both light and electron microscopic methods. Stellate cells with branching processes were reported in an abundant acid mucopolysaccharide stroma, and ultrastructurally these cells were seen to be fibroblast. Occasionally myxoblasts and macrophages were reported in the tumor. No odontogenic epithelium was identified, while an intracellular synthesis of cross-striated fibrils was observed. The ultrastructural features suggest that the connective tissue cell is the proliferating component of the tumor and is very similar to a fibroblast.

[Clinical anatomy of the human mental foramen].

BACKGROUND: The great diffusion of the surgical technics in oral implantology and the progress of the radiological imaging produces some interest for the clinical anatomy of the mental foramen (MF). The study, in addition to the measurements that define it, considers others anatomical features of practical utility and the variableness of them. METHODS: In the Anatomic Institute of the Bologna University, it has been made a morphometric revision of the MF on 100 dried mandibles of normal young adults (78 males, 32 females) random chosen with the complete integrity of the dental apparatus and of the mandibular bone criteria. The measurements have been made by anthropometric methods on the two sides of the same mandible (n = 200) and for everyone has been reported in the tables the medium, the maximum and the minimum values with their specific variation interval. The results are applicable to the common work conditions because they take in consideration among the specific characteristics of the MF in addition to the seat, the course of the mandibular canal, the thickness and the height of the mandibular bone. RESULTS: To the clinical and diagnostic imaging object the medium values of the anatomical measurements can be considered sufficent. To anthropometric, anesthesiologic and surgical aims it is also necessary the knowledge of the maximum and the minimum values and the variation interval. In the living man the anatomicomedical study of the MF is made by the diagnostic imaging, especially by computed tomography with specific algorithm, because it makes possible absolutely exact measurements. CONCLUSIONS: Finally, the specifications on the MF provided by the present study are important not only for an anatomical but also for a practical point of view because they are a datum point value in the patient clinical management.
