Steroid-induced anterior open bite. Case report

A young man presented with an increasing anterior open bite due to severe erosion and eventual collapse of the mandibular condyles. He had been undergoing immunosuppressive treatment, including high dose prednisolone, to treat the rejection of his renal transplant originally, and subsequently in connection with his mitral valve replacement following infective endocarditis. He also suffered severe secondary hyperparathyroid bone disease. A search of the English language literature failed to find a similar case.     

A survey of dental health and attitudes of adults in Queensland with respect to denture wearing

A postal survey was conducted in Queensland to investigate the dental health of adults with respect to denture wearing. The attitudes of the population to continuing attendance for dental care were also surveyed. Results obtained are compared with those for a very similar survey conducted in Victoria in 1977 and show that Queenslanders are exhibiting less edentulousness but have similar attitudes to denture wearing. The survey also indicates that cost is a large factor in determining the time at which dentures are replaced.     

Frontzahnstellung und Weichteilprofil—eine experimentelle Studie

Zusammenfassung Zahnlose Patienten mit noch guten Kieferverh?ltnissen, bei denen eine Versorgung mit Totalprothesen durchgeführt worden war, dienten als Modell, um die Auswirkungen einer systematischen Variation der Frontzahnstellung auf das Weichteilprofil studieren zu k?nnen. Dafür wurden Durchzeichnungen von bei verschiedenen Frontzahnstellungen gewonnenen Fernr?ntgenseitenbildern überlagert und miteinander verglichen. Es zeigte sich, da? die Auswirkungen von verschiedenen Faktoren abh?ngen. Der bisher kaum berücksichtigte Faktor „vertikale Lagerelation” erwies sich dabei als besonders bedeutsam.

Summary In order to study the effect of variation of the front teeth on the soft tissue profile, edentulous patients with good jaw relationships and fitted with dentures were taken as models. Radiographs were made with the front teeth in different positions and the tracings were superimposed and compared with one another. We saw that the effect depends on various factors. The factor “vertical position” proved particularly significant.

Résumé Afin d'étudier les effets de la variation systématique de la position des incisives sur le profil cutané, nous avons pris comme modèle des patients édentés qui portaient une prothèse, mais dont les machoires étaient encore en bon état. Après avoir radiographié les patients avec les incisives en différentes positions, nous avons superposé les radiographies et nous les avons comparées. Nous avons vu que l'effet produit dépend de plusieurs facteurs. Le facteur ?position verticale? s'est révélé être particulièrement significatif.
