    Notes: Specimens of oral mucosa were taken from alveolar mucosa, attached gingiva, cheek, floor of mouth, hard palate, lip, soft palate and tongue from vervet monkeys (Cercopithecus aethiops), and prepared for histological and histometric examination. Masticatory mucosa showed an epithelial-connective tissue union comprised of prominent thin rete pegs and connective tissue papillae. Lining mucosa had broader rete pegs and short connective tissue papillae. Elastic fibres were seen in all tissues except hard palate and attached gingiva. Histometric examination showed considerable variation in epithelial width and cell densities between the various epithelia. Tongue had the widest epithelium and alveolar mucosa the narrowest. Cell density was greatest in alveolar mucosa and least in cheek and floor of the mouth epithelium.

    Notes: The pulpal response to Protemp® (ESPE Gmbh) was compared to zinc oxide-eugenol, Super Syntrex (de Trey) and Protemp® plus zinc oxide-eugenol liner in 144 vervet monkey (Cercopilhecus pygerythus) incisor teeth, according to ADA Specification No. 41. Cellular displacement into dentinal tubules, superficial and deep inflammation were present only in the 3-day specimens in all materials. Mean scores for the test material were lower than both negative and positive controls. In the 30-day specimens the prevalence of reparative dentine under the test material was similar to the negative control, while at 90 days it was less than (he negative control, although the severity in affected specimens was more than the positive control. Use of a zinc oxide-eugcnol liner reduced the severity of reparative dentine formation.

    Notes: Specimens of clinically healthy oral epithelium from the vervet monkey (Cercopithecus aethiops) containing gingiva, alveolar mucosa and muco-gingival junction were examined histologically and with the scanning electron microscope.The gingiva was covered by a stratified squamous keratinized epithelium and the alveolar mucosa by a non-keratinized stratified squamous epithelium. A groove was present between the two epithelia in approximately half the specimens, the floor of which was lined by keratinized epithelium. Non-keratinized epithelial cells were seen to interdigitate with keratinized cells at the base of the alveolar mucosa side of the groove.

    Notes: The buccal and lingual gingival tissues in the vervet monkey were compared. Blocks of fresh tissue, consisting of mandible and associated soft tissues, were prepared for histological examination. Coronal and transverse sections, 7 and 25 μm thick, were cut through the full thickness of the mandible and stained with haematoxylin and eosin, picromallory and a variety of elastic stains. Photomicrographs of step serial sections were enlarged to standard magnification for histometric analysis. The buccal epithelium is thicker and shows a greater degree of keratinization than the lingual epithelium. The rete pegs are more prominent and penetrate deeper into the lamina propria on the buccal aspect. There appears to be two sets of elastic fibres in the submucosa on the buccal aspect and only one on the lingual. The buccal elastic fibres consist of a sub-epithelial plexus of fine fibres and a longitudinal set of thicker fibres. The lingual fibres are situated sub-epithelially only. The presence and orientation of the elastic fibres may be associated with the functional demands of flexibility and resiliency on the two epithelia.

    Notes: Portions of clinically healthy epithelium from the hard and soft palates, free and attached gingivae, cheek, floor of mouth and lip from the vervet monkey (Cercopithecus aethiops) were examined with the light and with the scanning electron microscope.The epithelia can be subdivided histolocally into keratinized and non-keratinized types. Each of these has a definite surface appearance irrespective of the region from which they are derived. Non-keratinized epithelia show a corrugated surface formed by microplications while keratinized epithelia have a cratered or pitted appearance. In addition, the parakeratinized free gingival surface may be masked by the presence of pellicle. The reason for the different surface appearances is obscure but may be related to different intercellular interdigitations in the two types of epithelia.
