A Novel Approach for Treating Fissure Caries
The problem of hidden caries
Current diagnostic methods
Previous and proposed solutions
Conservative cavity preparation
- Conservative cutting tip that removes less tooth structure than a 1/4 round bur.
- Bur head of sufficient length to extend to the DEJ during a one-pass cut, but short enough to permit the neck/head interface to remain within the visual operating field thus permitting depth gauge function.
- Cavity profile consisting of smooth, divergent lateral walls with no sharp internal line angles, appropriate for adhesive restoration.
- Minimal cavity profile dimensions that will provide for explorer access to dentin when required, with minimal additional loss of tooth structure.
- Smooth, yet efficient cutting operation characterized by well controlled cut, efficient clearing of cutting debris, minimal vibration, and mini-mal heat production during cutting.
- Differential cutting action along the bur head providing very conservative cutting action at the bur tip with progressively efficient cutting toward the head/neck interface to permit effi-cient enamel removal at full cutting depth when required for gaining access to established dentin lesions.
