Digital dental photography. Part 7: extra-oral set-ups.

This part of our series specifically addresses extra-oral dental photography consisting of portraiture and dental laboratory pictures. Portraiture, which is achieved using three types of illumination, natural daylight, bi-lateral camera mounted flashes (as for intra-oral images) or studio flashes, can be further divided into full face and dento-facial compositions. These are necessary for various dental disciples including evaluation of aesthetics, orthodontics and oral surgery facial profile assessment. Dental laboratory photography includes documentation of plaster casts and indirect prostheses. [ABSTRACT FROM AUTHOR]
