Mirrors for dental photography are the front surface type and can be made from thick glass covered with a highly reflective surface or polished metal plates. The mirroring surface can be on one side or both sides of the mirror.
A mirror is usually coated with a metal surface, chromium for example. Chromium’s metallic behavior makes the light reflected back (about 65% percent of the reflection, which is why it has a greyish tint).
Chromium mirrors 65-70%
Rhodium mirrors 75%
Titanium mirrors 80%
Dielectric mirrors 99%
Mirrors will scratch over time during usage. Do not stack mirrors on top of each other. Do not put the mirrors into an ultrasonic cleaning device.
All mirrors used in dental photography should be autoclavable. Titanium coated mirrors are more resistant to the autoclaving process.
