A comparative study of platelet-rich plasma, hydroxyapatite, demineralized bone matrix and autologous bone to promote bone regeneration after mandibular impacted third molar extraction.
Objectives: 1) to compare mandibular bone regeneration by applying autologous bone, platelet-rich plasma and two biomaterials (synthetic calcium hydroxyapatite, and demineralized bone matrix), and thus establish the potential benefits of these biomaterials in the regeneration of postextraction alveolar bone, 2) to identify wich of them accelerates more bone regeneration and 3) to determine whether there are differences in the postoperative period (pain, swelling, trismus, infection) depending on the material used. Study Design: It consists in a prospective, controlled (with a split- mouth design) and double blinded study. We use as a model an easily reproducible non-critical bone defect: th…
Aplasia of the lacrimal and major salivary glands (ALSG). First case report in spanish population and review of the literature
Aplasia of the lacrimal and the major salivary glands (ALSG) is a rare disorder with scarce cases described in the recent literature. The pattern of genetic inheritance is autosomal dominant with variable expressivity. A 40 years male patient was referred to the Oral and Maxillofacial Service at the Hospital Universitario de A Coruna diagnosed with complete agenesis of all salivary glands. Our case it is the first of ALSG syndrome in the Spanish literature. Imaging tests are necessary to confirm the lack of formation of salivary glands and alteration of lacrimal system. A mutation of FGF10 has been proposed as the responsible of the syndrome. The management of the lacrimal alteration depend…
