Abstract
AbstractOrthodontic therapy applies forces to teeth, causing an inflammatory reaction in the periodontal ligament. This is repaired by remodeling of the periodontium, allowing tooth displacement. Although orthodontic therapy is mostly initiated during childhood and adolescence, the number of adults seeking this treatment is increasing as our society's esthetic awareness rises. However, adults may already have periodontal tissue abnormalities, rendering orthodontic treatment inefficient because a healthy periodontium is essential for success. Numerous risk factors have been linked to periodontal lesions, with orthodontic tooth movement possibly playing a minimal influence. Although such tissue damages are mostly of esthetic rather than functional concern for patients, restoration frequently requires invasive procedures. Autologous cells for the treatment of periodontal complications have grown in popularity as a less intrusive alternative. The present review analyzed the literature on the use of mesenchymal stem cells and oral tissue‐derived fibroblasts for the healing of periodontal defects that may be related to orthodontic tooth movement. Furthermore, the advantages and challenges of the two cell types have been examined. Although the number of clinical studies is currently limited, our study demonstrates that oral fibroblasts have the potential to be the next emergent frontrunners for tissue engineering in the periodontium.
