Abstract: | Intraindividual variations in the mutans streptococci measured by Strip mutans, in a 1-day and a 5-day period, as well as the effect of toothbrushing, were investigated. 30 subjects participated, and their levels of salivary mutans were estimated by a scale containing four steps. With the exception of three comparisons, time intervals of different lengths did not cause a deviation of more than one step. Comparisons made before and after toothbrushing yielded the same score in 22 cases, whereas two subjects showed a discrepancy of two steps. Clearly, in a short-term perspective, variations can certainly be found, but more pronounced discrepancies are rare. |
