Evaluation on the efficacy of processed hydrated and dehydrated amnion chorion membrane on the proliferation of periodontal ligament fibroblasts.

The purpose of the present study was to process and assess the effect of hydrated amnion chorion membrane and dehydrated amnion chorion membrane on proliferation of periodontal ligament (PDL) fibroblast cells. The amnion chorion membrane (ACM) from placenta of 18 systemically healthy patients was obtained from the Department of Obstetrics and Gynaecology. They were processed as hydrated and dehydrated based on different processing methods. The Periodontal ligament cells were obtained from periodontal ligament of freshly extracted premolars of systemically healthy patients, due to orthodontic reasons. The PDL cells were further cultured in laboratory and were exposed to hydrated and dehydrated amnion chorion membrane. The MTT assay was performed to assess the proliferation of PDL fibroblast cells after 24 and 48 h. The hydrated and dehydrated amnion chorion membrane showed proliferation of PDL fibroblasts after 24 and 48 h. The proliferation of PDL fibroblasts in hydrated (p = 0.043) and dehydrated (p = 0.050) amnion chorion membrane was statistically significant at the end of 24 and 48 h respectively. On inter-group comparison dehydrated ACM showed significant proliferation of PDL fibroblasts after 24 (p=0.014) and 48 h (p=0.019). Within the limits of the present study, it can be concluded: both hydrated and dehydrated amnion chorion membrane showed proliferationof PDL fibroblast cells. However, dehydrated ACM showed significant proliferation of PDL fibroblasts.
