Types of flashes and their applications in dental photography

Flash type		Use		Advantages and disadvantages
Single point		To capture anterior teeth (a small segment)		It casts a shadow, so the contour of anterior teeth can be readily appreciated in the photographs Not recommended for complete arch[10]
Ring flash		To capture complete arch		Not for anterior teeth photography Emits too much light, causes a flat and bland (due to the absence of shadow) captured image
Twin flash		For complete arch capture Can be used at different angulations. (45°; one on each side is recommended)		The second flash is used to cover the shadow whichis created by using a single-point flash
