Round 9: Tossup 8

These body parts are partly created by ameloblasts, whose activity creates tree-ring-like striae of Retzius. Bacteria that grow on these body parts like Streptococcus mutans (15[1]-5[1])are particularly destructive toward their cementum. A hook-shaped WHO probe is used to measure the depth of the sulcus between these body parts and the surrounding (*) gingival tissue. (10[2]-5[1])These 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 body parts (10[2])and can (10[1])demineralize their enamel. For 10 points, name these body parts including incisors, canines, and molars. (10[1])■END■ (10[1])
