fa Validity of caries risk assessment programmes in preschool children سلامت دهان و جامعه نگر Oral Health and Epidemiology پژوهشي Research <p> <strong>Objectives</strong></p><p>  Various programmes have been developed for caries risk assessment (CRA). Nevertheless, scientific evidence on their validity is lacking. This study aimed to compare the validity of 4 CRA programmes (CAT, CAMBRA, Cariogram, and NUS-CRA) in predicting early childhood caries. <strong></strong></p><p> <strong>Methods </strong></p><p> A total of 544 children aged 3 years underwent oral examination and biological tests (saliva flow rate, salivary buffering capacity and abundance of cariogenic bacteria mutans Streptococci and Lactobacilli). Their parents completed a questionnaire. Children's caries risk was predicted using the 4 study programmes without biological tests (screening mode) and with biological tests (comprehensive mode). After 12 months, caries increment in 485 (89%) children was recorded and compared with the baseline risk predictions. </p><p> <strong>Results</strong></p><p>  Reasoning-based programmes (CAT and CAMBRA screening) had high sensitivity (≥93.8%) but low specificity (≤43.6%) in predicting caries in children. CAMBRA comprehensive assessment reached a better balance (sensitivity/specificity of 83.7%/62.9%). Algorithm-based programmes (Cariogram and NUS-CRA) generated better predictions. The sensitivity/specificity of NUS-CRA screening and comprehensive models were 73.6%/84.7% and 78.1%/85.3%, respectively, higher than those of the Cariogram screening (62.9%/77.9%) and comprehensive assessment (64.6%/78.5%). NUS-CRA comprehensive model met the criteria for a useful CRA tool (sensitivity+specificity≥160%), while its screening model approached that target. </p><p> <strong>Conclusions</strong></p><p>  Our results supported algorithm-based approach of caries risk modelling and the usefulness of NUS-CRA in identifying children susceptible to caries. </p><p> <strong>Clinical significance</strong></p><p>  This prospective study provided evidence for practitioners to select tools for assessing children's caries risk, so that prevention measures can be tailored and treatment plan can be optimised. </p><hr><p></p><p> <strong>Source: </strong>Journal of Dentistry</p><p> <a href="http://www.jodjournal.com/article/S0300-5712(13)00154-1/abstract" target="_blank"><font color="#0000ff">Full Text</font></a></p> Early childhood caries, Caries risk assessment, Multifactorial modelling, Sensitivity, Specificity, Prospective study 0 0 http://idai.ir/browse.php?a_code=A-10-32-2192&slc_lang=fa&sid=1 Xiaoli Gao 100319475328460010305 100319475328460010305 Yes Dental Public Health, Faculty of Dentistry, The University of Hong Kong, 34 Hospital Road, Sai Ying Pun, Hong Kong Ivy Di Wu 100319475328460010306 100319475328460010306 No Orthodontics and Pediatric Dentistry, School of Dentistry, University of Michigan, 1011 N University Avenue, Ann Arbor, MI 48109-1078, United States Edward Chin Man Lo 100319475328460010307 100319475328460010307 No Dental Public Health, Faculty of Dentistry, The University of Hong Kong, 34 Hospital Road, Sai Ying Pun, Hong Kong Chun Hung Chu 100319475328460010308 100319475328460010308 No Oral Diagnosis and Polyclinics, Faculty of Dentistry, The University of Hong Kong, 34 Hospital Road, Sai Ying Pun, Hong Kong Chin-ying Stephen Hsu 100319475328460010309 100319475328460010309 No Oral Diagnosis and Polyclinics, Faculty of Dentistry, The University of Hong Kong, 34 Hospital Road, Sai Ying Pun, Hong Kong May Chun Mei Wong 100319475328460010310 100319475328460010310 No Dental Public Health, Faculty of Dentistry, The University of Hong Kong, 34 Hospital Road, Sai Ying Pun, Hong Kong
