An experimental study of incidence and prevalence (1), morphology (2) and proliferative activity (3) of the epithelial remnants of Malassez following orthodontic tooth movement of rat molars has been performed. It was observed that the experimental procedure influenced these 3 parameters of the marginal periodontal membrane. On the pressure side undergoing hyalinization, a marked reduction or a complete absence of epithelial remnants occurred.
On the tension side, increased prevalence of epithelial remnants occurred, compared to both the pressure side and to the control tooth. The epithelial remnants appeared to be transferred from a resting into a more proliferative state.
The present findings indicate that both pressure and tension produced by orthodontic tooth movement may influence the proliferative rate of the epithelial remnants.
