Abstract:
1. A lens for use with a light-curing device and that is sized and configured to be inserted at least partially within a dental preparation, the lens comprising: a hollow body that has a tapered profile and that includes a hollow interior region therewithin, the hollow body comprising: a base circumferentially extending around the body that is configured to be connected with the light-curing device in such a manner that light emitted from the light-curing device passes through the lens when in use; and a wall extending outwardly from the base and converging at an apex, the wall and apex bounding the hollow interior region, the wall and apex being configured such that, when the lens is coupled to a light curing device, light emitted by the light curing device passes through the hollow interior region before reaching the apex in order for the lens to transmit an increased quantity of light emitted by the light curing device through the apex in a forward direction when in use compared to a tapered lens that does not include a hollow interior region.
