The potential role of a size-scaling principle in orofacial movements for speech was examined by using between-group (adults vs. 5-yr-old children) as well as within-group correlational analyses. Movements of the lower lip and jaw were recorded during speech production, and anthropometric measures of orofacial structures were made. Adult women produced speech movements of equal amplitude and ve...

The embryonic head development, including the formation of dental structures, is a complex and delicate process guided by specific genetic programs. Genetic changes and environmental factors can disturb the execution of these programs and result in abnormalities in orofacial and dental structures. Orofacial clefts and hypodontia/ oligodontia are examples of such abnormalities frequently seen in...

Elemental diet in the treatment of orofacial Crohn's disease HISTORY A 12 year old boy presented via his orthodontist with a three month history of facial swelling and a one year history of intermittent diarrhoea. Examination revealed a pale boy with asymmetrical thickening of his cheeks, a buccal mu-cosal fold on the left, and friable mucosa on the right. Investigations revealed a mild hypochr...

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...

low-power lasers are a group of lasers with a power less than 500 mw and unlike high-power lasers they have no effect on tissue temperature; they produce light-dependent chemical reactions in tissues. the purpose of this study was to review the clinical applications of these lasers and their success rate in different studies in orofacial pains. the articles with the key word “low level laser th...

In the present study, the effects of intra-hippocampal microinjections of morphine (an opioid agonist) and naloxone (an opioid antagonist) were investigated in the formalin-induced orofacial pain in rats. Orofacial pain was induced by subcutaneous injection of formalin (1 %, 50 μl) in the upper lip region and the time spent of face rubbing was measured in 3-min blocks for 45 min. Formalin induc...

Mothers exposed to Antiepileptic drugs (AEDs) are at high risk to born babies with orofacial malformations such as cleft lips. About 9 percent of congenital abnormalities in babies of mothers with epilepsy relates to orofacial abnormalities. Maintaining safe antiepileptic drugs for millions of mothers with epilepsy is very important. Researches show that new AEDs have less side effects than the...

Orofacial clefts are one of the most common congenital anomalies. The incidence is approximately 1 : 500 to 1 : 550 births [1]. The group of orofacial anomalies is heterogeneous. It comprises “typical” orofacial clefts ((cleft lip (CL), cleft lip and cleft palate (CLP) and cleft palate only (CP)) and “atypical” clefts (median, transversal, oblique and other Tessier’s types of facial clefts)[1]....
