Studies using nonhuman primates have made marked contributions to our understanding of the anatomy and function of the primary somatosensory cortex (SI). Its ventral or inferolateral part (vSI) represents orofacial structures, such as the lips, periodontium, tongue, palate, chewing musculature, etc. This brain region is neurally interconnected with the ventral part of the primary motor cortex t...

The aims of the present study were to assess the influence of: a) trait anxiety on orofacial pain; and b) orofacial pain on state anxiety. Forty-four rats were initially exposed to the free-exploratory paradigm for the evaluation of their anxiety profiles. In accordance to the parameter "Percentage of time in the novel side", the animals were considered as presenting high or low levels of trait...

Although rare, Eagle syndrome should be always considered in the differential diagnosis in patients with chronic orofacial pain refractory to conventional treatments. Treatment is surgery and exeresis of the styloid process via a transoral or cervical approach depending on clinical and radiological features.

BACKGROUND Cerebral palsy (CP) is the main cause of severe physical impairment during childhood and has commonly shown oral motor association. It has been considered as the main cause of the high prevalence of problems in children's nutrition. Respiration, chewing, swallowing, speaking and facial expressionare part of the orofacial motor functions and when affected they can interfere in childre...

A harmonização orofacial é uma especialidade odontológica precedente da necessidade em ampliar e associar tratamentos entre as estruturas intra extraorais, reabilitando funções reestruturando unidades anatômicas que ao longo do tempo sofreram alterações, possibilitando restituir paciente confiança auto estima diversas faixas etárias. O objetivo trabalho salientar a importância lábio harmonia fa...

Calcium, through its various channels involves in local, spinal and supra-spinal transmission of pain. In the present study, we investigated the separate and combined treatment effects of verapamil (a calcium channel blocker), morphine (an opioid agonist) and naloxone (an opioid antagonist) on pain in the orofacial region of rats. Orofacial pain was induced by subcutaneous (SC) injection of for...

The first dilemma of facial pain patients is “who to consult”? Is this a dental problem or a medical one and who will be able to treat it most appropriately? There is no doubt that the dental conditions described by Renton in her first article are best managed by dentists.
