Can Hyaluronic Acid be used to Stabilize Traumatized Teeth ?

Objective: Dental trauma may occur during daily life because of unexpected accidents. These dental traumas may affect facial esthetics and self-image; thus, successful dental trauma treatment is important. The objective of our study is to determine whether hyaluronic acid (HA) may be used as a stabilizer in the periodontal ligament space of traumatized teeth. Methods: Ex vivo study of pig mandibular central incisors will be used as a dental trauma model. Mandible segments containing central incisors will be fixed in acrylic. The incisor will receive luxation trauma using a simple extraction procedure. Subsequently, some samples will receive periodontal injections of HA and other samples will be used as untreated controls, Mineral Oil or Saline. Traumatized samples will be tested for mobility using 1) manual tests, 2) the Periotest, and 3) a materials testing system (MTS).
