Deciduous first molars with the buccal gingiva in situ were obtained from three year old cynomologus monkeys 2 months and 4 months after gingivectomy. Of the four specimens examined to date, all showed formation of a new epithelial attachment consisting of hemidesmosomes and a basement lamina. In some areas this attachment apparatus connected the cells directly to the tooth surface. In other areas, “cuticular” structures were interposed between the attachment apparatus and the tooth surface. Although the layers intervening between the attachment apparatus and the tooth surface may represent acquired pellicles, they may also be due to denaturation of superficial layers of cementum. Any factor affecting the integrity of the epithelial tissue, the attachment apparatus or these “cuticles” could result in breakdown of the epithelial attachment.
