BACKGROUND: Orofacial clefts (OFCs), including nonsyndromic cleft lip with or without cleft palate (NSCL/P), are common birth defects. NSCL/P is highly heterogeneous with multiple phenotypic presentations. Two common subtypes of NSCL/P are cleft lip (CL) and cleft lip with cleft palate (CLP) which have different population prevalence. Similarly, NSCL/P can be divided into bilateral and unilateral clefts, with unilateral being the most common. Individuals with unilateral NSCL/P are more likely to be affected on the left side of the upper lip, but right side affection also occurs...

OBJECTIVES: Orofacial granulomatosis (OFG) is a chronic inflammatory condition affecting the orofacial area. Its connection to Crohn's disease (CD) is debated. Our aim was to describe a cohort of pediatric OFG patients in detail, study the long-term behavior of OFG and evaluate factors predicting CD in OFG patients. METHODS: We invited patients diagnosed with OFG at two university hospitals, Finland for a follow-up appointment. Patients (n = 29) were examined by a dentist and an otorhinolaryngologist using a structural schema...

Nonsyndromic cleft lip with or without cleft palate (NSCL/P) is a group of common human birth defects with complex etiology. Although genome-wide association studies have successfully identified a number of risk loci, these loci only account for about 20% of the heritability of orofacial clefts. The "missing" heritability may be found in rare variants, copy number variants, or interactions. In this study, we investigated the role of low-frequency variants genotyped in 1995 cases and 1626 controls on the Illumina HumanCore + Exome chip...

BACKGROUND: Nonsyndromic cleft lip with or without cleft palate (nsCL/P) is the most common orofacial birth defect with an aetiology involving both genetic and environmental factors. Genome-wide association studies (GWAS) have identified several genomic susceptibility regions for nsCL/P. In the present study, the three well established single nucleotide polymorphisms (SNPs) identified by GWAS (rs987525 at 8q24, rs7078160 at 10q25, and rs227731 at 17q22 loci) and one SNP identified by candidate gene study (rs642961 in IRF6 gene at 1q32 locus) were analysed for an association with nsCL/P in Slovak population...

BACKGROUND: Ebiino, also known as false tooth extraction, is a traditional practice done mainly in the remote areas of African countries, including Uganda. It involves the extraction of tooth buds in babies with common childhood illnesses such as fever, cough, and diarrhea. It is thought that the tooth buds are responsible for the ailments seen in these infants. The practice is performed by traditional healers using unsterile instruments. The complications associated with this dangerous practice have been mentioned in the literature and include anemia and septicemia, among others...

Definition and taxonomy This review deals with neuropathic pain of traumatic origin affecting the trigeminal nerve, i.e. painful post-traumatic trigeminal neuropathy (PTTN). Symptomatology The clinical characteristics of PTTN vary considerably, partly due to the type and extent of injury. Symptoms involve combinations of spontaneous and evoked pain and of positive and negative somatosensory signs. These patients are at risk of going through unnecessary dental/surgical procedures in the attempt to eradicate the cause of the pain, due to the fact that most dentists only rarely encounter PTTN...

Peter Svensson, Arne May
It is indisputable that the global scientific advances in headache research, be it bench or bedside, have benefited enormously from the operational diagnostic criteria published in 1988. Today, this classification system is indispensable. The reason for this success is a low inter-rater variability. In general, orofacial pain conditions are less well characterised - with the noticeable exemption of temporomandibular disorder pain. Tremendous work has been put into changing this, and significant progress has been achieved - in particular, in terms of the clinical implications and overriding conceptual models for oro-facial pain...

A 35-year-old woman was referred to the Department of Oral Medicine and Orofacial Surgery after several recurrences of an ossifying fibroma (OF) that affected the free and attached gingiva of the maxillary right central incisor. Surgery was performed with a complete excision of the lesion together with the surrounding healthy tissue up to the bone. To guide the healing of the anterior esthetic framework and the excised tissues, a porcine collagen matrix as an alternative to connective tissue graft was used...

REVIEW
Hitoshi Maezawa
The tongue plays important roles in a variety of critical human oral functions, including speech production, swallowing, mastication and respiration. These sophisticated tongue movements are in part finely regulated by cortical entrainment. Many studies have examined sensorimotor processing in the limbs using magnetoencephalography (MEG), which has high spatiotemporal resolution. Such studies have employed multiple methods of analysis, including somatosensory evoked fields (SEFs), movement-related cortical fields (MRCFs), event-related desynchronization/synchronization (ERD/ERS) associated with somatosensory stimulation or movement and cortico-muscular coherence (CMC) during sustained movement...

Background Many patients with mid-face or lower face craniofacial pain are diagnosed, based on accompanying signs and symptoms and features other than location, as either atypical migraines or atypical TACs. Distinguishing features of headache disorders as a cause of facial pain include the temporal pattern of pain, associated symptoms including light and sound sensitivity and nausea, cranial autonomic symptoms, and the lack of local triggering among others. Results An intraoral neurovascular pain has been observed, and was termed neurovascular orofacial pain (NVOP)...

BACKGROUND: Early Childhood Caries (ECC) has become a major public health concern worldwide, mostly affecting children from disadvantaged families in increasingly severe forms. This condition has been frequently reported to alter children's nutrition, growth and general development. It negatively impacts their quality of life, through painful episodes and severe eating difficulties. While this period is crucial for oral praxes development, the impact of dental state on oro-facial functions is poorly documented...

Of the available regenerative treatment options, craniofacial tissue regeneration using mesenchymal stem cells (MSCs) shows promise. The ability of stem cells to produce multiple specialized cell types along with their extensive distribution in many adult tissues have made them an attractive target for applications in tissue engineering. MSCs reside in a wide spectrum of postnatal tissue types and have been successfully isolated from orofacial tissues. These dental- or orofacial-derived MSCs possess self-renewal and multilineage differentiation capacities...

We investigated, using orofacial reactivity assessment, whether nonflavor context cues can elicit conditioned aversive reactions, and also whether context cues interfere, through blocking, with the reduction in taste palatability during taste aversion conditioning. Experiment 1 showed that a context previously paired with LiCl evoked aversive orofacial reactions, and also attenuated the reduction in palatability of a saccharin solution which was paired with LiCl in that context. In Experiment 2, this blocking effect was abolished when the rats were given nonreinforced exposure to the previously LiCl-paired context (context extinction) before aversive conditioning of the saccharin in compound with the context...

Rheumatoid arthritis (RA) is a systemic autoimmune disease characterized by chronic inflammation and synovial hyperplasia, which usually affects multiple joints. The temporomandibular joint (TMJ) becomes susceptible to the development of changes resulting from RA. The aim of this study was to evaluate the presence of TMD and degenerative bone changes in TMJ in patients diagnosed with RA (rheumatoid arthritis). The Research Diagnostic Criteria for Temporomandibular Disorders (RDC/ TMD) questionnaire was used for clinical evaluation of the TMJ and for TMD classification of 49 patients of both sexes and all ages...

Accumulating evidence suggests that epileptic seizures originating from the temporal lobe (TL) occur in cats. Typically, affected animals have clinically focal seizures with orofacial automatisms including salivation, facial twitching, lip smacking, chewing, licking, and swallowing. Motor arrest and autonomic and behavioral signs also may occur. Many affected cats have magnetic resonance imaging (MRI) changes within the hippocampus or histopathologically confirmed hippocampal sclerosis or necrosis. From the 1950s to the 1980s, cats frequently were used as animal models for neurophysiological experiments and electrophysiological studies, from which important basic knowledge about epilepsy originated, but which has been rarely cited in clinical veterinary studies...

The ascending pathway mediating proprioception from the orofacial region is still not fully known. The present study elucidated the relay of jaw-closing muscle spindle (JCMS) inputs from brainstem to thalamus in rats. We injected an anterograde tracer into the electrophysiologically identified supratrigeminal nucleus (Su5), known to receive JCMS input. Many thalamic axon terminals were labeled and were found mainly contralaterally in a small, unpredicted area of the caudo-ventromedial edge (VPMcvm) of ventral posteromedial thalamic nucleus (VPM)...

The objective of this study was to investigate the prevalence of live births with orofacial clefts in Brazil from 2009 to 2013, according to Brazil's federative units and regions, and correlate it with the number of corrective surgery procedures for cleft lip and palate performed through the Brazilian National Health System in the same period. The data were collected from the National Live Birth System (SINASC in Portuguese) and the Hospital Information System (SIH-SUS in Portuguese). The results showed that the average prevalence of oral clefts in the period was 5...
