Periodontal bacteria in supraqinqival plaque of children were examined. Microscopic and cultural methods were employed to detect orqanisms in patients aqed 1.5 to 11.5 years. Data collected suggest that there is an excessive amount of facultative orqanisms in plaque flora. Fusobacteria and S.sanquis are found to be indigenous in children. Findings indicate that colonization by anaerobes and facultative organisms occurs early in life. A.naeslundii colonizes early in life, while A.viscosus colonizes later in life. Colonization of S.mutans and spirochetes occurs more frequently when child nears school age. Primary dentition has more facultative organisms than mixed dentition. Spirochetes are more readily detected under microscopic examination than by cultural methods. Data on the effects of snacking suggest that high frequency of S.mutans is related to high frequency of eating. Antibiotic usage in relation to the colonization of spirochetes and S.mutans has no significant effect.Missing page 35.
