Numerous mandibular pathologies are diagnosed in the emergency department (ED). We present the case of a woman with severe right-sided mandibular pain who was found to have a pathological fracture and osteonecrosis of the jaw (ONJ). The etiology of ONJ was found to be associated to previous use of zoledronic acid to treat osteoporosis. The aim of this case report is to discuss the etiology, dia...

BACKGROUND Osteonecrosis of the jaw (ONJ) is a destructive bone process in patients undergoing bisphosphonate therapy and it is modulated by local and systemic factors. The purpose of this article is to determine the prevalence of ONJ in patients who have undergone intravenous bisphosphonate therapy, and relate the risk factors described to establish a protocol to reduce the risk of developing ...

METHODS A total of 616 subjects with varying severity of spinal pain or no spinal pain completed a questionnaire focusing on symptoms in the jaw, head and spinal region. A subset of the population (n = 266) were sample...

OBJECTIVE To compare the prevalence of tinnitus in temporomandibular disorder (TMD) patients affected by either jaw muscle pain, temporomandibular joint (TMJ) internal derangements, or TMJ arthrosis. METHODS The presence of self-reported tinnitus was assessed in 250 consecutive TMD patients and correlation analysis was performed with clinical TMD signs and symptoms. RESULTS Tinnitus prevale...

Jaw movement induced by stimulation of the neocortical jaw motor region was predominant in a jaw opening direction whereas that following stimulation of the amygdala was predominant in a jaw closing direction. Additionally, these two brain regions ...

The aim of the present investigation was to assess the psychological profile of a sample of patients with temporomandibular disorders (TMD) and to compare the psychometric scores between patients with pain of different diffusion, location, intensity and duration. One hundred and ten (N = 110) patients with painful TMD fulfilled three psychometric instruments. Pain features were assessed as cate...
