Standardized periodontal lesions were produced in rats by inserting silk ligatures into the gingival sulcus of the first mandibular molars for three weeks. Ligatures were removed and the tissue left to heal for 10 weeks. The newly formed dento‐epithelial junction was investigated electron‐microscopically and compared with the same structure in control animals with an intact periodontium. No differences were found between the experimental and the control animals. The existence of a sub‐lamina lucida (a substructure of the internal basement lamina) was confirmed, as described previously in monkeys.
