Clinical, radiological and histological study was done for six months at various intervals to evaluate biocompatibility of the material and compare the regeneration of the bone in the alveolar socket. The study showed that Chitra- Calcium Phosphate Cement (graft material) is biocompatible and has no significant soft tissue reaction. The material maintains the alveolar bone height when used to fill extraction sockets and accelerates bone regeneration in the extraction sockets. However a more elaborate study with a larger number of clinical cases is very much essential to be more conclusive regarding its efficacy.
