“…These protective characteristics of saliva depend mainly on its mechanical cleansing action the dilution and neutralization of plaque acid by buffering system, particularly bicarbonates. The role of saliva in the process of dental caries is well known [12][13][14][15][16][17] . Dreizen et al have demonstrated that concentration of saliva buffers varies in relation to number of caries 18) .…”

This study was conducted to investigate the relationship between results of a salivary buffer test (CAT21 Buf Test) and caries status in 507 preschool children, who were 4-6 years old in Ulaanbaatar City, Mongolia. The prevalence of caries in the preschool children was 96.1%, and the mean deft and d teeth were 8.1 and 7.2, respectively. The mean CAT21 Buf Test score was 53.3% for low risk (high buffer capacity) and 46.7% for high risk (low buffer capacity). When salivary buffer score was divided into two groups (high risk, low risk), mean deft differed a significantly between the two groups (ANOVA PϽ0.001). The high risk group had a mean deft higher than that of the low risk group. These results suggest that the CAT21 Buf Test is useful for clinical application in children. Furthermore, when the CAT21 Buf Test score was higher, a higher correlation was shown with caries status. organism is compelled to react against them. The most effective reaction is neutralization of the acids by saliva buffers, in much the same way that the organism protects itself against internal pH variations by blood buffering. The relationship between buffer capacity and caries activity has been of interest to many researchers 21-23). Our knowledge of the functions of individual bacterial and salivary constituents and their interactions has increased enormously in recent years 24-26). We now have a better understanding of their diagnostic importance in the determination of caries activity 27,28). Salivary diagnostics is now entering the realm of modern dentistry. The aim of the present study was to investigate the relationship between the results of the CAT21 Buf Test and caries status in Mongolian preschool children. Materials and methods Subjects of study Five hundred seven preschool children aged 4-6

“…All of the tests of acidogenic potential of saliva have been reported to correlate to some degree with caries activity. However, the correlation of many of them is weak or questionable (Kesel, 1943;Rickles, 1953;Gardner & Snyder, 1960;Snyder et al, 1962;Snyder et al, 1963). The best correlation appears to be obtained with the Snyder test (Snyder, 1960).…”

“…This test, however, does not correlate adequately with caries activity. (Sellman, 1950;Snyder et al, 1962;Snyder et al, 1963). Another method measures the oxygen uptake of saliva in the absence (Kroncke & Naujoks, 1956) or presence (Green et al, 1959) of substrate by manometric techniques.…”

“…Residual starch is determined by spot tests (Turner & Crane, 1944) or, colorimetrically, by the production of a blue starch iodine complex (Claycomb et al, 1956). Enzyme activity has also been measured by the release of glucose (Hess & Smith, 1948 Claycomb et al, 1956;Snyder et al, 1962;Snyder etal., 1963).…”

“…The test is not, however, predictive of increment of decay. Different investigators have found the test to vary from essentially useless in the prediction of caries (Boyd et al, 1949;Glass, 1952;Iyer, 1952), to a low or moderate correlation coefficient that is significant a t a group level, but of no value for individual prediction (Kesel, 1943;Marshall-Day et al, 1949;Snyder, 1951;James & Parfitt, 1954;Slack & Martin, 1956;Snyder et al, 1962;Snyder etal., 1963).…”

Interest in a new test for caries risk in adolescents undergoing orthodontic treatment

et al. 2009

It has been reported that patients undergoing orthodontic treatment present a high risk of caries. Recently, an immediate chair-side test was proposed, displaying the intra-oral lactic acid production of cariogenic bacteria. The aim of this 12-month follow-up prospective cohort study was to evaluate the association between having a high score on this test and caries occurrence in 110 young patients scheduled for orthodontic treatment. Caries occurrence was studied by Kaplan-Meier curves and Multivariate Cox models allowed the examination of its association with covariates. Fifty four patients developed at least one carious lesion during the follow-up period. At baseline, approximately 70% of the patients presented a high risk of caries according to the test and this number came close to 80% by the study's completion. According to the Kaplan-Meier estimator, 51% (CI(95%) 0.40, 0.60) of the sample would have developed at least one carious lesion during the follow-up. The test score was then associated with age, DMFT, and caries occurrence. This study showed that a high test score at baseline associated with a high DMFT predicted a high risk of caries (RR = 2.6). Taking the patient's age into consideration, an increase of 1 year resulted in a 10% decrease of the risk of caries occurrence (RR = 0.89). Within the limits of this longitudinal study, it may be concluded that this test is useful to evaluate the risk for dental caries in adolescents with orthodontic treatment. Furthermore, the distribution of the lesions in our sample suggests specific clinical approaches for this group of patients.
