OBJECTIVE To examine and compare social acceptance, social behavior, and facial movements of children with and without oral clefts in an experimental setting. DESIGN Two groups of children (with and without oral clefts) were videotaped in a structured social interaction with a peer confederate, when listening to emotional stories, and when told to pose specific facial expressions. PARTICIPA...

BACKGROUND Although the prevalence of oral clefts in China is among the highest in countries worldwide, little is known about its descriptive epidemiology. METHODS Data used in this study were collected from 1996 to 2005 using the nationwide hospital-based registry, the Chinese Birth Defects Monitoring Network. A total of 4,891,472 newborns (live or still births with 28 weeks of gestation or ...

BACKGROUND Nonsyndromic oral clefts are complex in cause and have multiple genetic and environmental risk factors. This retrospective, questionnaire-based, case-control study investigated the relationship between oral clefts and parental mental and physical health and social support. METHODS Three hundred forty-seven parents of children with nonsyndromic oral clefts and 420 controls were incl...

The occurrence of dental abnormalities affecting both the primary and permanent dentition in children with oral clefts has been well documented.1-5 These abnormalities can be in the number, morphology, or eruption pattern of the teeth and are more frequent in children with clefts than in children without clefts.1 Specifically, both supernumerary and fused teeth have been shown to occur with gre...

Nonsyndromic oral clefts are considered a problem of public health in Brazil, presenting a multifactorial etiology that involves genetic and environmental components, such as maternal alcohol consumption. Several candidate genes have been investigated to identify some association with nonsyndromic clefts risk. The epidermal growth factor (EGF) gene is implicated in the normal craniofacial devel...

UNLABELLED Background Several studies have examined the effects of folic acid fortification on the occurrence of orofacial clefts. This study was carried out to evaluate the impact of flour fortification with folic acid on oral clefts in Northern Iran. METHODS In this hospital based study from March 2006 to September 2009, we screened the total number of live births at all hospitals in Golest...

This study investigated the prevalence of oral habits in children with clefts aged three to six years, compared to a control group of children without clefts in the same age range, and compared the oral habits between children with clefts with and without palatal fistulae. The sample was composed of 110 children aged 3 to 6 years with complete unilateral cleft lip and palate and 110 children wi...

BACKGROUND Suggestive, but not conclusive, studies implicate many genetic variants in oral cleft etiology. We used a large, ethnically homogenous study population to test whether reported associations between nonsyndromic oral clefts and 12 genes (CLPTM1, CRISPLD2, FGFR2, GABRB3, GLI2, IRF6, PTCH1, RARA, RYK, SATB2, SUMO1, TGFA) could be confirmed. METHODS Thirty-one single nucleotide polymor...
