Magnifying Glass Aids Dentists
AIDED by an illuminated magnifying glass, dentists are now able to discover the minutest cavities in teeth without difficulty. Any slight discoloration of the tooth, indicating the presence of a flaw in the enamel, is immediately detectable under the glass. The glass has a bright lamp attached to its frame which illuminates the field of magnification. It can be adjusted to any position, simplifying the task of drilling out small cavities.
