Regenerative medicine in dentistry aims to utilize the body's natural healing mechanisms or advanced technologies to repair or replace damaged or lost tissues in the oral cavity, such as teeth, gums, and bone.

Regenerative dentistry utilizes various types of stem cells, including embryonic stem cells, adult stem cells, and induced pluripotent stem cells (iPSCs). Each type has its own advantages and disadvantages, and the choice depends on factors such as availability, ethical considerations, and the specific application.

Tissue engineering in regenerative dentistry involves the combination of cells, scaffolds, and bioactive molecules to create functional tissues that can replace or repair damaged or lost tissues in the oral cavity.

Guided bone regeneration (GBR) is a surgical procedure that uses a combination of bone grafts and membranes to stimulate bone growth and regeneration in areas where bone loss has occurred, such as around dental implants or in preparation for dental procedures like sinus lifts.

Regenerative medicine holds promise in treating periodontal disease by promoting the regeneration of lost gum tissue and periodontal ligament, preventing further bone loss and tooth loss, and improving the overall health of the gums and supporting structures.

Hydroxyapatite is a biocompatible material that is similar to the mineral component of natural bone and teeth. It is often used in combination with regenerative medicine techniques, such as bone grafting, to promote bone growth and regeneration.

Regenerative medicine in dentistry faces several challenges and limitations, including ethical concerns regarding the use of stem cells, technical difficulties in isolating and manipulating stem cells, and the high cost of regenerative medicine procedures.

Direct pulp capping is a dental procedure that involves placing a biocompatible material directly onto the exposed pulp tissue to promote its regeneration and preserve the vitality of the tooth.

Regenerative medicine holds promise in treating dentin hypersensitivity by promoting the regeneration of lost dentin, blocking the exposed dentinal tubules, and stimulating the production of new dentin by the pulp.

Guided tissue regeneration (GTR) is a surgical procedure that involves placing a barrier membrane between the root surface and the bone defect to promote the regeneration of lost periodontal ligament and bone tissue.

Regenerative medicine holds promise in treating oral cancer by promoting the regeneration of lost or damaged tissues after cancer surgery, improving the success rate of radiation therapy and chemotherapy, and reducing the side effects of cancer treatments.

Enamel matrix derivative (EMD) therapy is a regenerative medicine approach that involves applying a protein-based material derived from developing enamel to the tooth surface to promote the regeneration of lost enamel.

Regenerative medicine holds promise in treating TMJ disorders by promoting the regeneration of damaged cartilage and bone in the TMJ, reducing inflammation and pain, and improving the range of motion and function of the TMJ.

Socket preservation is a surgical procedure that involves placing a biocompatible material into the extraction socket immediately after tooth extraction to maintain the alveolar bone volume and promote the regeneration of lost bone tissue.

Regenerative medicine holds promise in treating dental caries by promoting the regeneration of lost tooth structure, preventing further decay and progression of the caries lesion, and reducing the need for invasive dental procedures.
