摘要

Streptococcus mutans is strongly associated with dental caries. The dextrans produced aid colonization of the organisms on tooth surfaces. S. mutans has been isolated wherever it has been looked for throughout the world. The organisms are found in almost all cases in carious lesions and on noncarious tooth surfaces, occlusal and interproximal sites are predominately colonized. Inferential evidence shows a definite relationship between the presence of S. mutans and caries development. Current information indicates if the organism could be eliminated in young adults it would be difficult to reacquire it. Use of iodine and fluoride preparations reduces prevalence of S. mutans, but never completely or permanently eliminates the organism. Reports are mixed on beneficial effects of dextranase in controlling or eliminating plaque. (Author)
