[Conceptions and facts on difficult primary dentition (author's transl)].

The appearance of the first teeth is often regarded as a particular effort of the child and associated with various complications. On the basis of clinical observations and histological investigations the statements and conceptions were looked into and the process of growth followed up closely for the purpose of clarifying physiological and pathological events, thus also differentiating facts from opinions and assumptions. Appropriate modes of behaviour are recommended.

The role of the dentist in the emergency room.

Although most of the problems seen by the dentist in the hospital emergency room are not life-endangering, they can still cause considerable difficulty for the patient and anxiety for the doctor when not treated quickly and effectively. To manage an emergency effectively requires a prepared plan of action. Such planning must participation of the physicians, nurses, and auxiliary emergency room personnel. Since oral and maxillofacial emergencies may present unfamiliar problems to them, they must be instructed in advance about their role in proper care of such patients. Likewise, the dentist must familiarize himself with the emergency room- its operation and its facilities. Through such cooperative efforts, effective patient management will be provided no matter what unforeseen situation may suddenly arise.

Influences of osteoclast deficiency on craniofacial growth in osteopetrotic (op/op) mice.

It is well known that the defect in bone resorption in osteopetrotic (op/op) mice brings about deformation of the cranium and failure of tooth eruption. However, the influences on longitudinal growth of the craniofacial skeleton have not been elucidated. This study was thus conducted to examine craniofacial morphology and longitudinal changes in the op/op mice by means of morphometric analysis with lateral cephalograms. Lateral cephalograms, taken every 10 days from 10- to 90-day-old mice, were analyzed on a personal computer for 11 measurement items. For the nasal bone region, the most prominent differences were found between the op/op and normal mice. The anterior cranial base and occipital bone height presented almost equivalent growth changes in both the op/op and normal mice. The size of mandible, meanwhile, was significantly smaller in the op/op mice than in the normal controls. The gonial angle was also significantly larger in the op/op mice than in the normal mice throughout the experimental period. Thus, substantial differences in craniofacial growth were demonstrated in various areas of the craniofacial complex, which are assumed essentially due to the lack of osteoclastic bone resorption during growing period. Since the difference became more prominent in the anatomic regions relevant to the masticatory functions, it would be a reasonable assumption that reduced masticatory function is also a key determinant for the less-developed craniofacial skeleton in the op/op mouse.

[Experimental study on supraeruption of the unopposed miniature pig molars].

Supraeruption of the molars in the absence of antagonist molars or without occlusal contacts was observed in a miniature pig. Tetracycline was used to label the new regenerated cementum and alveolar bone associated with the supraeruption. The results showed that the molar through root canal treatment migrated the same level as the molars with pulp, which means that the hydrodynamic and hydrostatic forces arising from the blood in pulp vessels look doubtful. Cementum and alveolar bone deposition was seen around the apical, cervical regions and under the furcation area. The thickness of the deposition layers was almost the same as the supraerupted volume from the model measurement.
