Methods: Teeth of 74 subjects were examined, and the DMFT index was calculated according to World Health Organization (WHO) criteria to determine the past caries experience. Caries activity tests were performed according to manufacturer's instructions. For Cariview ® test, plaque samples were collected from the tooth surface by using a sterile cotton swab and incubated at 37 o C for 48 h; an indicator was added to observe the color changes according to the plaque acidogenicity. The subjects were classified into three groups (Low, Moderate, High) according to the level of caries risk. The data were assessed using one-way ANOVA to compare the caries experiences of risk groups according to the caries activity test results, and the relationships between the caries activity tests and the DMFT index were evaluated. Results: The overall mean DMFT index was 5.70±4.42. There was a significant difference in the DMFT index among the caries risk groups (Low, Moderate, High) according to the Cariview ® test result (P=0.036). Further, there was a positive correlation between the Cariview ® score and the DMFT index (r=0.23, P=0.047) and between the Cariview ® score and the previous caries activity tests score (P<0.01). Conclusions:The new caries activity test (Cariview ® ) can be easily used at dental clinics and enables precise caries risk assessment.

Effects of a mouthwash containing Lespedeza cuneata extract on risk of dental caries: a randomized, placebo-controlled clinical trial

“…Cariview ™ kit (AIOBIO, Seoul, South Korea) is a new caries activity test kit that evaluates the acidity of organic acids secreted by microorganisms in plaque through color. Cariview ™ was used as a tool to reflect dental caries activity according to the manufacturer's instructions 26 . The buccal surfaces of #16 and #36 teeth in the oral cavity were rubbed with a sterile cotton swab, and then immediately put into the culture media.…”

Oral health status of inpatients with varying physical activity limitations in rehabilitation wards

“…Tooth mobility was assessed using a scale for rating visible tooth mobility [25] . After the oral examination was complete, a caries activity test (Cariview) was performed according to the manufacturer's instructions [26] . The total score ranged from 0 to 100, with scores of 0 to 40, 41 to 70, and 71 to 100 representing a low, moderate, and high risks, respectively.…”

Oral health of older residents in care and community dwellers: nursing implications

“…According to the manufacturer's standard, those who scored 70 or above were regarded as a high caries activity group (Jung et al. ).…”

“…Higher scores indicate more acid production by oral bacteria. According to the manufacturer's standard, those who scored 70 or above were regarded as a high caries activity group (Jung et al 2014).…”
