Packet 9: Tossup 8

These body parts are partly created by ameloblasts, whose activity (15[1])creates tree-ring-like striae of Retzius. Bacteria that grow on these body parts like Streptococcus mutans (15[2]-5[1])are particularly destructive toward their cementum. A (15[1])hook-shaped WHO (15[2])probe is used to measure the depth of the sulcus between these body parts and the surrounding (-5[1])(*) gingival tissue. (10[2]-5[1])These (10[1])body (-5[1])parts’ deciduous type erupt during infancy and are typically (-5[1])lost before (10[1])adulthood. (10[2])Sugar-fermenting bacteria form a biofilm (10[3])called plaque (10[2])on these (10[1])body parts (10[4])and can (10[1])demineralize their enamel. For 10 points, name these (10[1])body parts including incisors, canines, and molars. (10[1])■END■ (10[1])
