Objectives: The purpose of the present study was to determine and compare the surface microhardness of three brands of artificial molars to verify if there is a significant difference between them. Materials and Methods: artificial molars were used based on acrylic resin, 15 lower molars of each brand TRILUX®, Gnathostar® and Duratone-n®, the samples were prepared making a coronal cross section to obtain a flat, smooth surface and polished, it was placed in pvc dies with 1.5cm Autopolymerizable acrylic, the surface to be analyzed was dyed blue, to then be taken to the Duroline-M Metkon Microdurometer where 3 indentations were made for each sample with a force of 200 grams during 15 seconds obtaining the results in units of Vickers (Hv). Results: The TRILUX® brand molars had higher surface microhardness with an average of 24,306 ± 1.41Hv, followed by the morals Duratone-n® with 22.2...

 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...
