Cistos ósseos simples são lesões benignas, raras, que acometem o tecido ósseo. Podem ser considerados como pseudocistos devido à falta de revestimento epitelial e geralmente estão associados a traumas anteriores, que provocam a formação de hematoma intraosseo. A lesão acomete, principalmente, in...
ABSTRACT PURPOSE: To compare bone healing in mandibular vertical body osteotomies (MVBO) after fixation with a resorbable 2.0mm-profile fixation system in the first and third postoperative months in rabbits. METHODS: Twenty hemimandibles of ten rabbits were divided into two groups according to duration...

Summary Osteoporosis is a disease of ascending character in the world population; in this context, bone biomarkers are being increasingly studied in order to aid in the diagnosis and monitoring of these patients. The main objective of this study was a literature review of articles whose main theme was th...
The term heterotopic ossification refers to bone formation in normally non-ossifying tissue. It represents a benign, localized, self-limiting and well-circumscribed lesion, and the phenomenon is rather unusual in the immediate vicinity of bones. Likewise, it is very rare in soft tissues such as the gastr...
ABSTRACT Condylar hyperplasia is a disorder characterized by excessive and progressive growth affecting the condyle, neck, body, and mandibular ramus. Under this condition, mandibular growth occurs in all three planes of space, but more predominantly in one of them. Its etiology is controversial in its o...
Objetivo: O presente estudo objetivou avaliar as características morfométicas, histológicas e imunoistoquímicas do tecido ósseo coletado de pacientes portadores de hipertensão arterial sistêmica compensada pelo uso de medicamentos antagonistas do sistema renina-angiotensina-aldoesterona (SRAA). Ma...
La cirugía bariátrica es un recurso terapéutico cuyo uso para el manejo de la obesidad mórbida crece rápidamente. La intervención induce varios cambios en el perfil hormono-metabólico de los pacientes: disminuye la absorción de calcio, caen los niveles de vitamina D, se produce un hiperparatiroid...

Bisphosphonates are the first choice therapy for the pharmaco logical treatment of osteoporosis. Following reports of cases of bisphosphonaterelated osteonecrosis of the jaw and atypical femur fracture, the safety of longterm use of bisphosphonates has been evaluated, resulting in the proposal of stronti...
