| Tooth development occurs through the interaction between oral tissues during embryogenesis. Alteration through odontogenesis may cause tooth morphological alterations, one of these could be Dens evaginatus. This anatomical variation could be originated from an abnormal proliferation and folding of a portion of the inner enamel epithelium and subjacent ectomesenchymal cells of the dental papilla into the stellate reticulum of the enamel organ during the bell stage of tooth formation. Dens evaginatus is defined as a tubercle, or supplemental solid elevation on some portion of the crown surface. Inadequate clinical management of these teeth may result in a pulpal exposure and possible loss of vitality of the tooth. The research wants to report a case of Dens... |

| We determined and analyzed risk factors of hepatitis C virus (HCV)-infected Brazilian hemophiliacs according to their virological, clinical and epidemiological characteristics. A cross-sectional and retrospective study of 469 hemophiliacs was carried out at a Brazilian blood center starting in October 1997. The prevalence of HCV infection, HCV genotypes and factors associated with HCV RNA detection was determined. The seroprevalence of anti-HCV antibodies (ELISA-3.0) was 44.6% (209/469). Virological, clinical and epidemiological assessments were completed for 162 positive patients. There were seven (4.3%) anti-HCV seroconversions between October 1992 and October 1997. During the same period, 40.8% of the positive anti-HCV hemophiliacs had abnormal alanine... |
