He had bilateral post-axial polydactyly (figure 1). He never experienced any respiratory difficulty and there was no history of apnoeic episodes. The central nervous syste...
Joubert syndrome is a rare autosomal recessive disorder. It is characterized by congenital ataxia, hypotonia, developmental delay and at least one of the following features: neonatal respiratory disturbances and abnormal eye movements; including nystagmus and oculomotor apraxia. Molar tooth appearance is an essential finding for the diagnosis of Joubert syndrome. We report a five-days-old newbo...
Ameloblastic fibrodentinoma (AFD) is a rare benign mixed odontogenic tumor that occurs predominantly in children and young adults. AFD is usually associated with delayed eruption of the tooth and shows painless swelling. We present a case of AFD affecting an 8-year-old Japanese girl with a complaint of delayed eruption of her left mandibular second premolar tooth. Intraoral examination did not ...
Nowadays, with the applications of titanium dioxide nanoparticles (TiO2-NPs) in pharmacy, food industry, cosmetics, toothpaste and sunscreens, pregnant women are exposed to nanoparticles. Since tooth development is vuln-erable to environmental impacts and mandibular first molar bud develops before maxillary first molar bud, in this ex-perimental study the effects of TiO2-NPs on the development ...
Joubert syndrome is a clinically and genetically heterogeneous ciliopathy characterized by a typical cerebellar and brainstem malformation (the "molar tooth sign"), and variable multiorgan involvement. To date, 24 genes have been found mutated in Joubert syndrome, of which 13 also cause Meckel syndrome, a lethal ciliopathy with kidney, liver and skeletal involvement. Here we describe four patie...
Joubert Syndrome (JS) in adult population is extremely rare. Here, we describe the first adult case seen in the Republic of Turkey. Our patient, a 19-year-old male, was diagnosed primarily by magnetic resonance imaging (MRI) finding of the typical “molar tooth sign”, in addition to JS clinical features such as mental retardation, hypotonia, dysarthria, nystagmus and ataxia. Detailed images of h...
Joubert syndrome (JS) is an inherited disorder characterized by transient episodic hyperpnea, ataxia, and vermian hypoplasia. Typical imaging findings of JS include hypoplasia or aplasia of the cerebellar vermis, thick and elongated superior cerebellarpeduncles and an abnormally deep interpeduncular fossa with 'molar tooth sign'. We present a case of JS associated with deep cerebral sulci and f...
Objective: Impacted tooth develops when the fails to erupt into its anatomical functional position. Theaim of this prospective study was find out common clinical effects impacted lower molar on adjacent tissuesand evaluate relationship between signs and symptoms as regards gender agerespectively. Material Methods: Data for were obtained using a well-structured questionnaireat Teem Dental Hospit...
Background and Aim: The third molar tooth lies with symptoms such as periodontal problems, caries, crowding, root resorption, cyst and tumor formation of the adjacent second molar. The purpose of this study was performed to evaluation of the position of mandibular third molar teeth and its effect on second adjacent molar teeth. Materials and Methods: Panoramic radiography were obtained from 26...
