The Doctors Eyes Occlusal Mirror No. 11 (55mm) is a glass dental mirror that uses an ultrabright coating, yielding near 100% reflectivity. This gives dentists truer color representation and provides more detail for intra-oral images. Each Occlusal Mirror is highly durable and built to withstand autoclaving up to 390°F. The removable silicon handle can also be autoclaved with the dental mirror.
