Calculus attaches to tooth surfaces by all of the following EXCEPT hemidesmosomes. mechanical locking to tooth/root irregularities. organic pellicle. close adaption to cementum. 9. The difference in the color between subgingival and supragingival calculus is related to Haemolysis of erythrocytes pH of the saliva Death of the leukocytes All of the above 10. The dentogingival unit is composed of Junctional epithelium and gingival fibers None of the above PDL fibers and gingival fibers Junctional epithelium and PDL fibers 11. Which of the following PDL fibres prevent extrusion of tooth Horizontal fibres Transseptal fibres alveolar crest fibres Oblique fibres 12.
