Cariogram and Oratest in Caries Risk Assessment for School Children

Aims and objectives: The present study was carried out to evaluate the correlation between Cariogram and Oratest in caries risk assessment among school children. Materials and Methods:A clinical diagnostic trial including 240 healthy school children using Cariogram and Oratest to predict the dental caries risk for each individual.The data required for Cariogram construction (diet contents and frequency, the related general diseases, the use of fluoridated toothpaste, tooth brushing and other fluoride supplements, past dental history and dental plaque scores) were collected by dietary questionnaire, interview and clinical examination.Oratest was carried out for the same patients after performing the Cariogram.The analysis of collected data was performed using SPSS version 22 software program.The p-values ≤ 0.05 was considered statistically significant.Results: There were statistically significant differences for all risk factors and Oratest scores between low and high caries risk individuals classified by Cariogram.A highly significant positive correlation between the green sector of Cariogram (chance of avoiding development of caries in future) and Oratest scores, highly significant negative correlations between both Cariogram and Oratest and dental caries status were found.Children with Oratest time less than 64.43 minutes are at high caries risk.
