Abstract
A light shield is provided for dental apparatus which shines light onto light curable material used to repair teeth. The shield is formed of a plastic material which substantially attenuates light in the blue range, and can be mounted onto the guide tube of the light gun utilizing engagement members defined between slits cut in the plastic sheet forming the body of the shield. The engagement members between the slits are displaced as the light shield is pressed onto the tip of the guide tube, with the engagement members then resiliently pressing against the periphery of the guide tube to firmly hold the shield in place. The shield can be easily removed by the dentist after the procedure with the patient is completed, and is economical so that it may be disposed of after one use.
