The BULL rule in dentistry is an occlusal adjustment principle for posterior teeth, standing for "Buccal of Upper, Lingual of Lower," guiding dentists to adjust the inclines of the upper buccal (cheek-side) cusps and lower lingual (tongue-side) cusps to correct premature contacts, especially on the working side, while preserving functional cusps for stable chewing. It helps maintain proper bite alignment by selectively grinding non-functional inclines to resolve interferences and ensure smooth jaw movements.
