 The Traumatic Bone Cyst is an intraosseous cavity that appears in the jaw of young patients. One of the most accepted theories is about bleeding inside the bone due to trauma, instead of the correct formation of the clot, the liquefactive necrotic clot is reabsorbed in another way, forming the cyst. The first objective of this clinical case is to return the functionality and correct health of the patient. The second objective is linked to the presentation of a specific clinical case, which will allow us to illustrate the treatment of the Traumatic Bone Cyst of a 16-year-old male patient, who attended an orthodontic consultation, being referred to an interconsultation with the surgery area. maxillofacial, due to discomfort in the lower right quadrant when chewing. As a complementary examination, the computerized axial tomography CT scan shows a radiolucent shadow compatible with a "bone...

 The quality of the root canal filling is today considered a factor of great importance in the success of endodontic treatment. The three-dimensional filling with thermoplastic injection prevents percolation and microfiltration towards the peri-apical tissues of the root canal. With the help of a combined technique of vertical condensation and thermoplasticized gutta-percha, working times are reduced and we obtain favorable results, but it depends on an excellent biomechanical preparation that facilitates the entry of instruments at the time of obturation.The present clinical case focuses on performing an endodontic treatment with manual protaper biomechanical preparation, thermoplastic filling and vertical condensation in the dental clinic of the Equinoctial Technological University, in the city of Quito-Ecuador. The current use of techniques with thermoplasticized gutta-percha allows ...
