Conventional orthodontic appliances use mechanical forces to modify the position of tooth/ teeth into a more favorable position. However, scope these fixed are greatly restricted by certain morphological conditions which caused due deviations in developmental process or neuromuscular capsule surrounding orofacial skeleton. To overcome this drawback, myofunctional came being. These considered be...

Teeth morphology has been widely used in taxonomic, biological and fossil teeth studies of Chondrichthyes. Herein, dental abnormalities in Amblyraja doellojuradoi are described. Almost 10% of 182 specimens sampled presented any of these types of dental anomalies: (1) an additional incomplete tooth row between two complete rows, (2) an increasing tooth base size and division of its cusps until t...

Dental disease and its prevention and treatment comprises approximately 10% of the general equine practitioner’s work. The most common disease affecting the equine hypsodont teeth is the development of dental overgrowths. Brachydont dentition (canines and wolf teeth) are less often diagnosed with dental disease. Gingivitis and periodontal disease as seen in many young horses can affect any toot...

A case of multiple pulp stones, a supernumerary tooth and a congenitally missing tooth accompanied by several developmental dental anomalies concurrently affecting the upper and lower anterior teeth in an Iranian healthy girl is reported. Developmental tooth abnormalities are usually found in conjunction with certain diseases or conditions. In the present case, although the patient had consangu...

From the debate over developmental "universals" in Piagetian theory and the controversy between developmental and difference theories of mental retardation, an important hypothesis emerges—one that is testable via cognitivedevelopmental comparisons between retarded and nonretarded persons. This similar sequence hypothesis holds that retarded and nonretarded persons traverse the same stages of c...

Genetically modified corn Bt11 is insect-resistant and expresses Cry1Ab toxin, an insecticidal protein, in kernels. Although Bt11 corn is considered safe based on animal performance, there are no reports available on the clinico-biochemical effects of feeding it to cattle. In this study, we evaluated the effects of feeding Bt11 to calves, using blood and ruminal clinico-biochemical parameters. ...

the witkop syndrome is a rare autosomal dominant disorder characterized by the absence of several teeth and abnormalities of the nails. this is the first report of a rare genetic tooth and nail syndrome diagnosed in a 2.5-year-old boy with early exfoliation of the primary canine, absence of the primary incisors, and nail dysplasia. a homozygous mutation was identified in 3’-utr of msx1 gene in ...

Vascular reflexes were assessed in 17 adult patients with Charcot-Marie-Tooth disease using the Valsalva manoeuvre, and the pulse rate and systolic blood pressure responses to standing. Six patients showed abnormalities consistent with an autonomic neuropathy. One patient had giant nerve fibre bundles in the myenteric plexus of bowel resected for co-existent Crohn's disease, indicating histolog...

We report prenatal and neonatal neuroimaging findings in a case of oral-facial-digital syndrome type VI (OFDS VI). Prenatal MR imaging at 29 weeks' gestation showed hypoplastic cerebellar vermis and hemispheres, the molar tooth sign, and a hypothalamic hamartoma. Neonatal MR imaging confirmed these findings. The neonate developed breathing abnormalities and exhibited frontal bossing, multiple b...

Parents often are concerned with “lumps and bumps” that appear in the mouths of children. Pediatricians should be able to distinguish the normal clinical appearance of the intraoral tissues in children from gingivitis, periodontal abnormalities, and oral lesions. Recognizing early primary tooth mobility or early primary tooth loss is critical because these dental findings may be indicative of a...
