It also occludes open dentin tubule and thus reduces the dental sensitivity. It also occludes open dentin tubules and thus reduces the dental sensitivity. Their binding to the teeth also occludes open dentin tubules, helping to reduce dentin hypersensitivity. HEMA forms deep resinous tags and then occludes the dentinal tubules. The second layer however occludes the dentinal tubules and strongly adheres to the canal walls. Structural analysis by X-ray crystallography indicates that antibody binding partially occludes putative carbohydrate binding pockets. This suggests that the ball occludes the channel by binding electrostatically rather than covalently. Additionally, the enlarged fourth mandibular tooth occludes into a pit in the rostrum. Earth totally occludes direct solar radiation within the umbra, the central region of the shadow.
