ABSTRACT Developmental disorders of human dentition may result in various abnormalities according to etiologic agents and the developmental period involved. The size, shape number teeth be affected. Dental can occur singly or multiples an individual not associated with syndromes. Complementary radiographic examinations are valuable for diagnosis, especially lesions that asymptomatic detected on...

Macrodontia is a dental condition where tooth or group of teeth are abnormally larger than average. Functional and aesthetic discrepancies may arise in affected individuals resulting lowering the quality life. It has been noted that macrodontia associated with several genetic endocrine abnormalities. Among which, KBG syndrome rare disorder characterized by developmental This case report provide...

We examined 502 subjects, 247 of whom had occupational elemental mercury exposures 20 to 35 years previously, to identify potential exposure-related neurological abnormalities. Few significant (p less than 0.05) differences existed between exposed and unexposed subjects. However, multiple linear regression analysis demonstrated several significant correlations between declining neurological fun...

PURPOSE The objective of this study was to compare postobturation flare-ups following single and two-visit endodontic treatment of molar teeth with periapical radiolucency. MATERIALS AND METHODS A total of 100 patients with asymptomatic molar teeth with periapical radiolucency were selected. They were randomly allocated into two groups. Fifty patients received complete endodontic treatment in...

A talon cusp is a relatively rare dental developmental anomaly characterized by the presence of accessory cusp-like structure projecting from the cingulum area or cementoenamel junction. It is frequently found on the palatal surface of the maxillary anterior teeth in the permanent dentition. The etiology is controversial, but it is suggested that this condition has a multifactorial cause, inclu...

Facial-Digital Syndrome Type VI Oral-facial-digital syndrome type VI (OFDS VI) or Váradi-Papp syndrome is a rare autosomal recessive disorder, distinguished from other type of OFDS by metacarpal abnormalities with central polydactyly; cerebellar abnormalities; and, sometimes, hypothalamic hamartomas. Affected patients present with hypotonia, cognitive impairment, irregular breathing, and oculom...

In peripheral nerve myelin, the intraperiod line results from compaction of the extracellular space due to homophilic adhesion between extracellular domains (ECD) of the protein zero (P 0 ) glycoprotein. Point mutations in this region of P 0 cause human hereditary demyelinating neuropathies such as CharcotMarie-Tooth. We describe transgenic mice expressing a full-length P 0 modified in the ECD ...

Hyperdontia or supernumerary teeth without associated syndrome is a rare phenomenon, as supernumerary teeth are usually associated with cleft lip and palate or other syndromes such as Gardner's syndrome, cleidocranial dysplasia, and so on. Five patients with supernumerary teeth visited our department. They had no familial history or other pathology, certain treatment protocols was modified due ...

Teeth are conspicuous features of many leaves. The percentage of species in a flora with toothed leaves varies inversely with temperature, but other ecological controls are less known. This gap is critical because leaf teeth may be influenced by water availability and growth potential and because fossil tooth characters are widely used to reconstruct paleoclimate. Here, we test whether ecologic...

We performed percutaneous CT-guided needle biopsies with a transfacial approach in the diagnosis of lesions of the parapharyngeal region. Via the buccal space, core needle biopsy specimens were obtained in eight patients with known parapharyngeal abnormalities identified by CT and/or MR imaging. In all cases, sufficient tissue was obtained to provide a definitive histologic diagnosis. There wer...
