A study of the connective tissue surrounding the developing tooth in the vervet monkey.

Developing teeth in the Vervet monkey (Cercopithecus aethiops) were examined at various pre-eruptive stages. A longitudinal arrangement o f periodontal fibres was seen grouped alongside the hone and cementum and parallel to them. These fibres later ex­ tended coronally, passing around the reduced enamel epithelium. It was difficult to compare this study to other species as there were differences in terminology and in the precise stages o f development described. There was however a suggestion that the pre-eruptive periodontalfibre arrangement in the vervet monkey is similar to that in man. OPSOMMING
