1. Regenerative endodontics

2. Basic Understanding What is regenerative endodontics ? Regenerative endodontics is a branch of dentistry focused on restoring the function and vitality of damaged or diseased dental pulp through biological processes, including tissue engineering and stem cell therapy. Discuss the primary goals of regenerative endodontic procedures. The primary goals are to eliminate infection, promote the regeneration of healthy pulp tissue, restore the normal function of the tooth, and potentially allow for continued root development. How does regenerative endodontics differ from traditional endodontic treatments? Traditional endodontic treatments focus on removing infected pulp tissue and sealing the root canal system, whereas regenerative endodontics aims to regenerate healthy pulp tissue and restore the tooth's vitality.

3. Biological Basis Explain the role of stem cells in regenerative endodontics . Stem cells are crucial in regenerative endodontics as they have the ability to differentiate into various cell types necessary for the regeneration of pulp and dentin tissue. What types of stem cells are commonly used in regenerative endodontic procedures? Commonly used stem cells include dental pulp stem cells (DPSCs), stem cells from human exfoliated deciduous teeth (SHED), and stem cells from the apical papilla (SCAP). Discuss the significance of the pulp-dentin complex in regenerative endodontics . The pulp-dentin complex is significant because it includes the dentin-producing odontoblasts and the vascular and neural components necessary for the tooth's sensory function and health.

4. Clinical Procedures Describe the typical clinical protocol for a regenerative endodontic procedure. The protocol usually involves disinfecting the root canal system, placing a scaffold material that promotes tissue growth, and delivering stem cells and growth factors to the treated area. What are the key steps involved in a regenerative endodontic treatment? Key steps include canal disinfection, minimal instrumentation to preserve stem cells, placement of an intracanal medicament, blood clot induction, placement of a scaffold, and sealing the access with a temporary or permanent restoration. How is the success of a regenerative endodontic procedure assessed clinically? Success is assessed through clinical symptoms (absence of pain or swelling), radiographic evidence of continued root development or apical healing, and response to vitality tests indicating the presence of healthy pulp tissue.

5. Materials and Techniques What materials are commonly used as scaffolds in regenerative endodontics ? Common scaffolds include blood clots, platelet-rich plasma (PRP), platelet-rich fibrin (PRF), and various biocompatible synthetic materials. Discuss the role of growth factors in regenerative endodontics . Growth factors such as bone morphogenetic proteins (BMPs), transforming growth factor-beta (TGF- β), and vascular endothelial growth factor (VEGF) play a crucial role in cell proliferation, differentiation, and tissue regeneration. How are antimicrobial agents used in regenerative endodontic treatments? Antimicrobial agents like calcium hydroxide, triple antibiotic paste, or low-concentration sodium hypochlorite are used to disinfect the root canal system, eliminating bacteria and creating a conducive environment for tissue regeneration.

6. Indications and Contraindications What are the indications for regenerative endodontic procedures? Indications include immature permanent teeth with necrotic pulp and open apices, non-responsive teeth to traditional endodontic therapy, and teeth with significant tissue loss requiring regeneration. Discuss the contraindications and limitations of regenerative endodontics . Contraindications include teeth with severe calcifications, root fractures, patients with systemic conditions affecting healing, or those unable to maintain oral hygiene. Limitations include unpredictable outcomes and the need for more long-term clinical studies. Which patient factors are considered when determining suitability for regenerative endodontic treatment? Factors include the patient's age, overall health, the extent of infection or damage, ability to attend follow-up visits, and commitment to maintaining oral hygiene. Outcomes and Prognosis What are the expected clinical outcomes of regenerative endodontic procedures? Expected outcomes include resolution of symptoms, regeneration of healthy pulp tissue, continued root development, and restoration of tooth function. Discuss the factors that influence the success rate of regenerative endodontic treatments. Factors include the initial disinfection level, type of scaffold and growth factors used, the presence of viable stem cells, the patient's immune response, and the technique's adherence to protocol. What are the potential complications associated with regenerative endodontics ? Potential complications include failure to achieve pulp regeneration, persistent infection, root canal recontamination, and lack of root development or apical closure.

7. Case Studies Present a case study where regenerative endodontics was successfully implemented. What were the key factors that contributed to the success? A case study might involve a young patient with an immature necrotic tooth treated with disinfection, a scaffold of platelet-rich fibrin, and a follow-up showing continued root development and symptom resolution. Key factors include effective disinfection, the use of a biocompatible scaffold, and proper follow-up care. Analyze a case where regenerative endodontics failed. What were the possible reasons for the failure? A failure case might involve persistent infection or lack of root development. Possible reasons include inadequate disinfection, insufficient stem cell viability, poor scaffold integration, or patient non-compliance with post-operative care.
