Oral and gingival health research

Horizontal serial sections of human, mon­ key and rat jaws reveal a compact band of connective tissue encircling the teeth within the marginal gingiva. This cir­ cumferential band is seen in normal tis­ sue of the three species. The purpose of this presentation is to describe this con­ nective tissue band and discuss its func­ tion. The circular band is best seen in hori­ zontal sections of healthy submucosa un­ derlying the epithelium of the margin of the gum. It is composed of many con­ nective tissue cells with their closely in­ terwoven collagenous fibers forming a compact well-differentiated group. Some of the fibers are embedded in the cementum of the teeth, others in the crest of the alveolar bone, although the large majority are not attached to bone or cementum but form an encircling band within the gingival margin.
