Figure 7. Transmission electron micrograph illustrating the basal lamina, consisting of the lamina lucida (LL) and the lamina densa (LD), and hemidesmosomes (HD) at the interface between the junctional epithelium and the tooth. The interposed matrix layer (*) may be a dental cuticle or a modified cementum matrix. The micrograph originates from a healthy but receded gingival site of a human tooth. AEFC, acellular extrinsic fiber cementum; CK, cytokeratin filaments.
