Regeneration of supporting tissue to tooth surfaces affected by periodontitis has long been an ideal goal of periodontal therapy. Periodontitis affected root surfaces are hyper mineralized and contaminated with cytotoxic and other biologically active substances. Such surfaces are not biocompatible with adjacent periodontal cells, the proliferation of which is pivotal for periodontal wound healing. Traditional surgical and non-surgical periodontal therapies aim at arresting periodontal disease by removal of plaque- invested tissues from disease-affected roots. However complete removal appears not possible with only mechanical debridement. Thus, root conditioning has been recommended as an adjunct to mechanical root surface debridement to remove smear layer and root associated endotoxins and to expose collagen fibers on the dentin surface. A number of agents have been proposed which when applied remove the smear layer, eliminate the cytotoxic material like endotoxins, uncover and widen the orifices of dentinal tubules and expose the dentin collagen matrix. This collagen matrix is thought to provide a substrate which supports chemotaxis, migration and attachment.

Biomimetic dentistry is an interdisciplinary approach and has potential for transforming everyday dental practice. It brings the power of modern biological, chemical, and physical science to solve real clinical problems. Each chapter in this textbook gives you insight of how biomimetic materials function as root canal sealer, filling materials, cements and root and crown repair material and possesses features as like strengthening the root following obturation, good sealing ability, enhanced biocompatibility and antibacterial properties. Contemporary biomaterials have shown ability to overcome the limitations of traditional materials. Hence the future dentistry would involve the use of biomimetic materials which could successfully replace lost enamel, dentin, cementum and even the pulp tissue.
