[Possibilities of in vivo identification of various types of fissures in human teeth].

In consideration of the fact that the results from the visual appreciation of the fissures in freshly extracted teeth agree with the findings from thin sections of the same teeth, the authors developed a stereomicroscopic method for assessing in vivo the occlusal surfaces of human teeth. The great percentage of accurate assessments of wide fissures obtained with this method permits to recommend it. Narrow fissures may be ascertained by exclusion.

[Localization and frequency of interglobular dentin in human premolars from regions with various fluorine contents in the drinking water].

Using a light microscope, the authors compared 484 longitudinal ground sections of human premolars from a region where the drinking water contains 1.0 p.p.m. of fluorine withe 777 preparations from a region where the drinking water contains 0.35 p.p.m. of fluorine. Water fluoridation of fluorine supply during tooth development does not lead to a statistical significant change in the occurrence of interglobular dentine areas. Additional analyses justify at best the suspicion that teeth (and in particular female teeth) which developed under the influence of fluorine show a greater variability as to the occurrence of interglobular dentine areas.

[Diagnosis of frequent periodontal diseases by the specialist for general dentistry].

It is reasonable to refer a patient to a specialist or a special clinic if the own diagnostic possibilities are not sufficient to elucidate the case. But the own diagnostic possibilities should be fully used to spare the patient unnecessary travelling and loss of time. The most reliable and important symptoms and the local causes of frequent periodontal diseases are described and tabulated. All the symptoms indicated may be verified in any institution by inspection, palpation, measuring of socket depth and radiological examination. In this way the specialist is general stomatology will be aided in establishing a periodontal differential diagnosis.

[Self evaluation and objective dental findings].

In the course of a stomatological study, 354 students were asked for a self-assessment of their dental and oral hygiene and of their dental state. The results obtained were compared with those from an objective evaluation of the dental and oral hygiene and of the dental state of these individuals. Furthermore, the authors made inquiries about oral hygiene habits and knowledge of health, using anonymous questionnaires, 352 of which could be evaluated. Owing to the considerable overestimation of their dental and oral hygiene and of their dental state by the students, there was a great discrepancy from the objective findings, which existed also between the actual knowledge of health and its regular and deliberate application.

[Comparative radiological studies on the incidence of primary caries in treated vital and devitalized teeth].

The non-filled proximal areas of 709 vital and devital teeth with metal fillings were examined radiologically for primary caries. The findings were almost identical (Table 2). The somewhat higher prevalence of primary caries in vital teeth (Table 1) may be explained by the more drastic removal of predilection sites in devital teeth, which is due to the necessarily more extended cavity preparation.
