      A photographic black contraster is a tool for dental photography that provides a black background to isolate the teeth of interest. The black color neutralizes the background, making it easier to visualize color matches or mismatches.

      Contemporary dental photography: selection and application.
      Rigid contrasters can be made of anodized aluminum or aluminum steel alloy and soft contraster of malleable stainless steel or copper sheet covered with medical grade plastic silicone rubber, which is latex-free, safe, and hypoallergenic. Contrasters are sterilized in an autoclave up to 135 °C and available in different shapes to allow anterior, lateral, and occlusal photographs, as well as of different sizes including large, medium, or small adult arches and for pediatric use.
      Contrasters are available from dental suppliers. However, they are relatively expensive, and usually multiple contrasters are needed for different intraoral photographs. The following article describes a cost-effective and straightforward technique to fabricate an intraoral photographic contraster by using a kitchen solid nylon turner or spatula. A nylon turner is inexpensive, heat-resistant, stain-resistant, safe to use, and autoclavable. In addition, it has a long contra-angled handle for improved convenience and accessibility.
