Once- versus twice-daily aspirin treatment in patients with essential thrombocytosis.

Insufficient platelet inhibition has been reported in up to 40% of aspirin-treated patients, including patients with essential thrombocytosis. To maintain sufficient platelet inhibition, a shorter dosing interval with aspirin has been suggested. We aimed to investigate the antiplatelet effect of low-dose aspirin given twice-daily compared to standard once-daily dosing in patients with essential thrombocytosis.

The influence of impaction on the rate of third molar mineralisation in male black Africans.

One of the main criteria used in dental age diagnostics in living adolescents and young adults is assessment of the mineralisation stage of the third molars. In the case of Europid populations, it has been established that impaction status has an influence on the rate of mineralisation of the third molars. In view of this, a study was undertaken to determine whether the chronological process of wisdom tooth mineralisation is dependent upon impaction status in black Africans too.

Studies of the chronological course of wisdom tooth eruption in a Black African population.

The importance of forensic age estimation in living subjects has grown over the last few years. In dental age estimation, tooth eruption is a parameter of developmental morphology that can be analyzed by either clinical examination or by evaluation of dental X-rays. In the present study, we determined the stage of wisdom tooth eruption in 410 male and 106 female Black South African subjects of known age (12-26 years) based on radiological evidence from 516 conventional orthopantomograms.

Comparative study on the effect of ethnicity on wisdom tooth eruption.

The current knowledge base for evaluating the influence of ethnic origin on wisdom tooth eruption is still inadequate. We therefore analyzed and compared the chronology of wisdom tooth eruption in three ethnic populations-German, Japanese, and black South African-based on evidence from 2,482 conventional orthopantomograms. The investigated German population ranked in the middle in terms of the age of wisdom tooth eruption.

Studies on the progress of third-molar mineralisation in a Black African population.

The forensic determination of the age of living people has become increasingly important in recent years. With regard to the relevant age group, the radiographic assessment of third-molar mineralisation is of particular importance. So far, the influence of geographic origin on the mineralisation rate has been insufficiently analysed.
