Recent studies have provided evidence for sensory-motor adaptive changes and action goal coding of visually guided manual action in premotor and posterior parietal cortices. To extend these results to orofacial actions, devoid of auditory and visual feedback, we used a repetition suppression paradigm while measuring neural activity with functional magnetic resonance imaging during repeated intr...

Objectives: Crocin, a constituent of saffron and yellow gardenia, possesses anti-nociceptive effects. In the present study, we investigated the effects of intra-fourth ventricle injection of crocin in a rat model of orofacial pain. The contribution of opioid system was assessed using intra-fourth ventricle injection of naloxone, an opioid receptor antagonist. Materials and Methods: A guide cann...

Previous findings have shown that saffron (Crocus sativus L.) extract and its active constituents produce antinociceptive effects in the rat models of orofacial pain. In the present study, the central H2 histaminergic and alpha-2 adrenergic receptors involvement in crocetin-induced antinociception in orofacial formalin pain in rats was evaluated.The guide cannula was implant...

The aim of this study was to establish the prevalence of orofacial pain and its impact on the daily performance of workers in the textile industry in the municipality of Laguna, Brazil. A cross-sectional study involving all workers (n= 267) of the five textile industries of the municipality in 2004 was conducted. Data were obtained through the questionnaire proposed by Locker and Gruska to meas...

Orofacial clefts include cleft lip (CL), cleft palate (CP), and cleft lip and palate (CLP), which combined represent the largest group of craniofacial malformations in humans with an overall prevalence of one per 1,000 live births. Each of these birth defects shows strong familial aggregation, suggesting a major genetic component to their etiology. Genetic studies of orofacial clefts extend bac...

BACKGROUND Alzheimer's disease (AD) affects not only memory but also other cognitive functions, such as orientation, language, praxis, attention, visual perception, or executive function. Most studies on oral communication in AD focus on aphasia; however, speech and orofacial apraxias are also present in these patients. The aim of this study was to investigate the presence of speech and orofaci...

AIM (1) To study the behavior disorders in children between 5 to 15 years. (2) To study the role of stress in causing behavior disorders. (3) To interpret the orofacial findings in children with behavior disorders. (4) Correlate the orofacial findings with behavior disorder. MATERIALS AND METHODS Ninty children with behavior problems between age of 5 to 15 years along with their parents who v...

The orofacial area is central for several vital functions such as breathing and eating. The orofacial area also acts as the basis for social interaction, emotional communication, facial expression and speech communication. Normal orofacial sensorimotor development is necessary for these functions to develop and mature in the child, hence orofacial dysfunction may be severely disabling. In the o...

BACKGROUND To determine the clinical characteristics of Continuous Neuropathic Orofacial Pain in patients that suffer Persistent Idiopathic Facial Pain (PIFP), Painful Post-Traumatic Trigeminal Neuropathy (PPTTN) or Burning Mouth Syndrome (BMS) and to describe their treatment. MATERIAL AND METHODS A retrospective observational study was made, reviewing the clinical history of the patients dia...
