    Examination of the oral cavity is an integral part of every clinical examination. The clinical presentation of various viral conditions is discussed in this article and will provide the family practitioner with an up to ...
  • A pilot study to determine the effects of skin contact on two commonly used dental impression materials 
    Steyn, N.; Botha, Stephanus Johannes; Brand, Paul D.; Bernitz, Herman (International Organisation for Forensic Odonto-Stomatology, 2006-12)
    Impression materials used in the analysis of bite marks are required to maintain their stability and integrity for extended periods. It has been observed that certain impressions taken of skin lose their properties with ...
  • Implant failure due to titanium hypersensitivity/allergy? - report of a case
