Glandular odontogenic cyst (sialo-odontogenic cyst): report of two cases and literature review of 45 previously reported cases.

The clinical, radiological, histopathological and immunohistochemical (cytokeratin) features of two cases of glandular odontogenic cyst (GOC) are presented and discussed in a review of 45 cases of GOC hitherto reported. Of cases with available information, 34 occurred in the mandible and 6 in the maxilla; the male:female ratio was 19:28, and the mean age was 46.7 years in males and 50.0 years in females. Six cysts recurred once after 2-8 years (mean 2 years 8 months) and 2 (5.3%) recurred twice after 2 and 5 years and after 3 and 5 years, respectively, giving a rate of recurrence of 21%. The identification of osteodentin in one of the present cases and the co-expression of cytokeratins (CK) 13, 19 and 8 strongly support the concept of odontogenic differentiation in the GOC. Careful surgical removal of the lesion succeeded by a 5-year follow-up period is recommended.

Palatine and mandibular tori. A morphologic study in the current Norwegian population.

Five thousand Norwegians, 2783 females and 2217 males, ranging in age from 16 to 89 years, have been screened for the presence of torus palatinus and/or torus mandibularis and analyzed with regard to size and shape of tori, sex, and age. The tori have been classified according to size as small, medium, and large. No measurements have been made, consistent with the view that these characteristics are non-metrical and should be assessed by means of a standard procedure. The prevalence figures of both tori were fairly low, in accordance with former reports. In torus palatinus there was female predominance, with a sex ratio of 5:3. In torus mandibularis the males were in majority, and the sex proportion was 4:3. In both sexes prevalence of the two tori was highest in the 35- to 65-year age group. Further analysis indicated in both tori a real correlation between prevalence and size and some correlation also between size and shape of torus palatinus but not of torus mandibularis. The figures of concurrence of the two tori were low, denoting a non-significant correlation. Still, the analysis showed that each torus occurred more than twice as frequently in an individual bearing the other torus. Torus morphoanalysis, explaining diverging patterns of clinical conduct in the two tori, and the relative weight of hereditary versus environmental factors as morphogenetic determinants of the condition, including a quasi-continuous genetic or threshold model, have contributed to shed new light on the torus phenomenon. The occurrence and propagation of torus mandibularis complies reasonably well with this model, and the present analysis indicates that even torus palatinus should appropriately be considered a threshold character.

[Odontology and the disabled elderly--an unsolved social problem].

An outline of the state of dental and oral health in the disabled elderly population in Norway is presented with reference to the existing legislation in this field, which, however, has failed to function according to intention and expectancy. Various aspects of the problems are discussed and a number of factors pointed out, considered to be of paramount importance for a solution of this enbarrasing situation, unworthy of our welfare society.

[Oral surgical treatment in elderly patients. 1].

A survey is presented on the basic principles of oral surgery in ageing and aged patients. This paper deals with the preoperative evaluation of the patient, followed by a presentation of the most important geriatric diseases with special surgical implications.

[Oral surgical treatment in elderly patients. 2].

A survey is presented on the basic principles of oral surgery in ageing and aged patients. Problems of local anesthesia are taken up and relevant surgical procedures in the elderly presented. Some essential pathophysiological factors are pointed out, related to the ageing process and with bearing upon surgical treatment in old people generally.
