| Abstract |
|
The aims of this study were to compare the status of dental caries between mental retarded persons(MR) and normal persons and investigated the association among dental caries and oral factors(plaque index, S. mutans, Lactobacillus, buffering capacity, salivary total IgA and anti-S. mutans IgA titers). DMFS index and plaque index were significantly greater in the MR person group than in the normal person group. The concentration of S. mutans-specific IgA was significantly greater in the normal person group than in the MR person group, but that of salivary total IgA was not show the significant difference. Salivary buffering capacity was significantly greater in the normal person group than in the MR person group, but the counts of salivary S. mutans and Lactobacillus were not significantly different. By age group(I: 9-11Y, II: 12-14Y, III: 15-18Y), DMFS index and plaque index were significantly greater in the MR person group than in the normal person group at III. The S. mutans counts and Lactobacillus counts were significantly greater in the normal person group than in the MR person group at I, but those were contrary at II, III. There was a high correlation among caries index and buffering capacity, level of S. mutans and Lactobacillus, plaque index at III. |
