The position of the bolus in persons with mandibular prognathism was examined using a cineradiographic method before and after surgical correction of the prognathism. The pre-operative study included 30 persons, 18 women and 12 men. The test foods were bread and toffee. The results showed that...
In the resting position and in persons with normal jaw relations the lips have a mutual surface of contact. Clinically, the area of contact constitutes a well-defined zone. This contact zone was made visible by smearing with ointment and measured in 24 young and 21 older persons. In all subjects...
Penetration of bacteria into the tubules of intact dentin exposed by fracture was compared in vitro in pairs of teeth, one of which in each pair was mounted with an intrapulpal hydrostatic pressure equivalent to 30 mm Hg. The teeth were incubated at 37°C for 21 days. Intra-pair comparisons in...
In 58 embedded teeth and 126 follicles it was found that the enamel-forming epithelium could be heavily disturbed especially in narrow fissures and at the cemento-enamel junction by premature reduction preventing the enamel from being fully mineralized. The congestion of capillaries in the...
Extra-cellular neutrophil collagenase and elastase were demonstrated by immunochemical methods in crevicular material from clinically healthy and chronically inflamed human gingivae. Collagenolytic activity was shown by viscosimetry and elastolysis by its digestive action on elastin agarose...
52 totally or partially embedded teeth were studied in ground sections by soft microradiography to assess the quality of the enamel and the dentine. In 79 % the dentine was more or less globularly mineralized. In 50 % the dentine-enamel junction (D.E.J.) was more scalloped than normally and in...
The sensitivity of experimentally exposed dentin, where the conditions at the outer tubule apertures were changed by various treatments, was studied in 40 contralateral pairs of teeth by intra-pair comparison. The results showed: (1) Dentin areas exposed by fracture were more sensitive than...
