“…5). Halitosis generates as a result of the metabolism of microorganisms and is closely related to the growth of microorganisms in the oral cavity, and control of oral microorganisms is essential to inhibit the generation of halitosis (Jeon et al, 2015). Therefore, WEA can control oral microorganisms as well as inhibit the generation of halitosis through anti-oral microbial activity and inhibition of oral microbial growth.…”

Apple contains nutrients such as sugars, dietary fiber, and vitamins as well as bioactive phytochemicals such as organic acid, fatty acid and phenolic compounds. This study was conducted to confirm the applicability of apples as a bleaching agent and functional substances for the prevention of oral infectious diseases and maintenance of oral health by investigating the bovine teeth bleaching effect, anti-oral microbial activity, and inhibitory effect of halitosis of water-extracted apple (WEA). From the results of quantitative analysis of the surface color of bovine teeth, the application of WEA significantly increased the ΔE value, indicating a bleaching effect. In the case of 100mg/ml, the ΔE value increased as the WEA application time increased, and the bleaching effect was the greatest. Based on the results of the disk diffusion test and selective culture using CRT bacteria test kit, WEA showed anti-oral microbial activity against the dental caries bacteria, Streptococcus mutans and Latobacillus casei, the periodontal bacteria, Aggregatibacter actinomycetemcomitans, and Eschericha coli, but showed no antifungal effect against Candida albicans, causing oral candidiasis. From the results of colony formation and generation of halitosis from salivary microorganisms, WEA inhibited the growth of salivary microorganisms and generation of components inducing halitosis such as hydrogen sulfide, methyl mercaptan and dimethyl sulfide, that occur during the metabolic process of oral microorganisms. Therefore, WEA is a functional substance derived from a safe and useful natural product that can be used for the prevention of oral infectious diseases and maintenance of oral health

This study aimed to compare the results of conventional methodology and real-time polymerase chain reaction (PCR) for acid-producing bacteria and identify the appropriate method for caries activity testing. Methods: Oral examination and caries activity tests, such as the CRT ® Bacteria test and modified Snyder test, were conducted on 33 middle school students in Cheongju, South Korea. Pearson correlation analysis was subsequently performed with a significance level of 5%. Results: The amount of Streptococcus mutans determined using the CRT ® Bacteria test was highly correlated with the decayed teeth (DT) index (R=0.570, P<0.05); decayed, missing, and filled teeth (DMFT) index (R=0.376, P<0.05); and dental health capacity of the first permanent molar (R=-0.395, P<0.05). The amount of Streptococcus mutans determined using real-time PCR was significantly associated with the DT index (R=0.528, P<0.05), DMFT index (R=0.369, P<0.05), and dental health capacity of the first permanent molar (R=-0.426, P=0.013). Conclusions: There was a significant correlation between the amount and the type of bacteria between the CRT ® Bacteria test and real-time PCR; therefore, these tests were found to be more appropriate to determine caries activity than the modified Snyder test. This study suggests that realtime PCR is a better technique for detecting caries activities than conventional techniques, such as the CRT ® Bacteria test and modified Snyder test, because it is easy to use and provides accurate results.
