Item Mitotic activity in the oral epithelium of the albino rat(1976) Cleaton-Jones, P.In groups of Wistar rats 3 and 12 months of age, colchicine and radioautography were used to assess mitotic activity in oral epitheliums. Apparent mitotic activity in the epitheliums of the cheek, hard palate, and central, intermediate, and lateral zones of the soft palate depended on the method used and the age of the rat.Item Radioautographic study of mesenchymal cell activity in the secondary palate of the rat(1976) Cleaton-Jones, P.Fifteen µCi of ³H-thymidine was injected into the amniotic cavity of fetal rats from day 15 to 19 postinsemination. Analysis of radioautographs from these rats did not show increased mesenchymal cell activity to be responsible for medial rotation of the palatal shelves. Variations in cell activity in the older fetuses were mainly due to developing bone and glands.Item A quantitative study of soft tissue specimen shrinkage during preparation for scanning electron microscopy(1975) Wilton-Cox, H.; Cleaton-Jones, P.Item Relative analgesia (Nitrous Oxide Sedation)(1974) Cleaton-Jones, P.Item The palatal vault in adult South African Bantu-speaking Negroids(1970) Cleaton-Jones, P.Item A simple viewing table for clinical and research use(1975) Volchansky, A.; Austin, J. C.; Cleaton-Jones, P.Item A macroscopic and microscopic study of the development of the rat palate including the soft palate(1976) Cleaton-Jones, P.Item Papain induced changes in cartilage(1969-02) Dreyer, C. J.; Cleaton-Jones, P.Item A scanning electron microscope study of the developing rat secondary palate(1976) Cleaton-Jones, P.The surfaces of the developing secondary palatal shelves and palate, in Wistar strain albino rats, were examined using scanning electron microscopy. Beginning on the 16th day after insemination there was a progressive degeneration of the cell surfaces on the medial aspect of the shelves. This took the form of a loss of surface microvilli and intercellular boundaries accompanied by the appearance of clefts between the cells. Fusion of the palate was complete by the 18th day and two epithelial zones could be recognized in the soft palate. The cell surface degeneration is possibly an essential change prior to shelf fusion.Item Dental health related to oral hygiene and academic instruction in a group of dental students(1963) Cleaton-Jones, P.
