The healing process is a complex and integrated sequence of events initiated by the stimulus of injury. It requires the well – orchestrated action of many specialized cell types to restore structural and functional integrity. Unlike other wounds in the body, in periodontal wounds, there is a mineralized tissue interface at the junction of epithelium and connective tissue. The understanding of this process is necessary to visualize the outcome of different periodontal procedures, which inhibits the further progression of periodontal disease and restore the lost periodontal structures. Periodontal tissues undergo regeneration or repair according to the response to various periodontal therapies employed. The complex nature of this process can be understood better in the future to develop periodontal procedures resulting in complete regeneration of periodontal tissues.
