The relationship between nasal obstruction and craniofacial growth is unclear. The literature indicates that upper-airway compromise produces chronic mouth breathing, especially in the dolichocephalic (narrow-faced) child. It has been shown that a greater tendency exists toward the skeletal pattern associated with long face syndrome in dolichocephalic head types. Therefore, it becomes difficult...

Past investigations of Down's syndrome (DS) have indicated that there are marked abnormalities in the craniofacial morphology. The aim of this study was to establish the craniofacial anthropometric variables which discriminate DS group from healthy population and also to observe the changes occurring with growth. Using noninvasive method of craniofacial anthropometry, craniofacial pattern profi...

Craniofacial area is apart of the human body which undergoes the greatest changes during development and is characterized by uneven growth. External and internal factors affect the growth and development of craniofacial structures. They are responsible for the occurrence of specific craniofacial characteristics in different races or populations within the same race. The present study investigat...

Polycystin 2 (Pkd2), which belongs to the transient receptor potential family, plays a critical role in development. Pkd2 is mainly localized in the primary cilia, which also function as mechanoreceptors in many cells that influence multiple biological processes including Ca(2+) influx, chemical activity and signalling pathways. Mutations in many cilia proteins result in craniofacial abnormalit...

introduction: nager syndrome is a malformation resulting from problems in the development of the first and second branchial arches and limb buds. the cause of the abnormal development of the pharyngeal arches in nager syndrome is unknown. it is also unclear why affected individuals have bone abnormalities in their arms and legs. nager syndrome is thought to have an autosomal recessive inheritan...

OBJECTIVE To compare the craniofacial growth characteristics of untreated subjects with Class II division 1 malocclusion with those of subjects with normal (Class I) occlusion from the prepubertal through the postpubertal stages of development. MATERIALS AND METHODS The Class II division 1 sample consisted of 17 subjects (11 boys and six girls). The Class I sample also consisted of 17 subject...

background: zinc (zn) is an essential nutrient that is required in humans and animals for the growth, development, and maintenance of healthy bones. the aim of this study is to investigate the effects of zinc-defi cient nutrition on the dental, mandibular, maxillary, and cranial dimensions of rats. materials and methods: this experimental study was carried out on 14 male wistar rats. the rats w...

Cross-sectional studies have demonstrated an association between craniocervical angulation and craniofacial morphology. It was the aim of the present study to determine if the growth coordination suggested by this association could be detected in a longitudinal analysis of growth changes in posture and craniofacial morphology. The sample comprised 43 children, 20 girls and 23 boys. Cephalometri...

objective: silybum marianum has been used for centuries in herbal medicine for treatment of liver diseases. currently, there is no data available on the possible effects of silymarin on fetal development. this study aimed to investigate the teratogenic effect of silymarin on balb/c mice fetuses. materials and methods: a total of 40 pregnant mice were divided into 4 groups of 10 mice each. three...

Knowledge of normal eye development is crucial for the development of retinal rescue strategies. I shall focus on two signalling pathways that affect retinal development. Fibroblast growth factors function in retinal cell proliferation, retinal ganglion cell axon guidance and target recognition, craniofacial patterning and lens induction. Hedgehog proteins are required for progression of the ne...
