Oro-facial manifestation of hypohidrotic ectodermal dysplasia--case report.

A case report of Hypohidrotic Ectodermal Dysplasia is presented. The oro-facial features are described together with the dental management of the condition. Children who have this condition should be treated early for their prosthodontic needs to aid mastication and appearance. Continued review and replacement of dentures provided should be instituted for the growing child.

Processing factors affecting the clarity of a rapid-curing clear acrylic resin.

The difficulty in repeatedly producing unblemished, clear acrylic resin in the dental laboratory has hindered its wider use, despite its many advantages over coloured material. Recently, rapid-cure dental acrylics have been introduced, which are available in both clear and coloured forms. This investigation examined various factors which may influence the production of unblemished, rapid-curing, clear acrylic resin. Utilizing a quantitative assessment of clarity, the most important factor influencing the clarity of the resin is shown to be the choice of separating medium. Tin-foil produces extremely high clarity, but alginate mould separator causes surface blanching. However, this surface blanching can be removed by polishing. Porosity, caused by too rapid curing, and stone model dryness are of only secondary importance. Possible water contamination of the monomer liquid due to accidental exposure only affects clarity at very high levels of contamination.
