Claims1
A method of coating the internal surfaces of a post hole located in a tooth comprising the steps of:
- forming a post hole in a tooth to a predetermined depth,
- placing a fluent dental material intended to line the interior surfaces of a post hole onto an applicator having an applicating end defined as an elongated spiral having minute radially extending flocking disposed along the longitudinal length of said spiral,
- said applicating end so formed being of a size to be received in said post hole formed in a tooth,
- rotating said dental applicator so formed so that the radially extending fibers are rotated whereby the spiral causes the fluent dental material on the applicating end to be placed onto the interior surface of the post hole in an up and down movement as the applicator is rotated to ensure a uniform coating of the internal surfaces of a post hole,
- and removing the dental applicator from the post hole upon the coating of the internal surfaces of said post hole.
