Validation of a multifactorial risk factor model used for predicting future caries risk with nevada adolescents

Abstract

BackgroundThe objective of this study was to measure the validity and reliability of a multifactorial Risk Factor Model developed for use in predicting future caries risk in Nevada adolescents in a public health setting.MethodsThis study examined retrospective data from an oral health surveillance initiative that screened over 51,000 students 13-18 years of age, attending public/private schools in Nevada across six academic years (2002/2003-2007/2008). The Risk Factor Model included ten demographic variables: exposure to fluoridation in the municipal water supply, environmental smoke exposure, race, age, locale (metropolitan vs. rural), tobacco use, Body Mass Index, insurance status, sex, and sealant application. Multiple regression was used in a previous study to establish which significantly contributed to caries risk. Follow-up logistic regression ascertained the weight of contribution and odds ratios of the ten variables. Researchers in this study computed sensitivity, specificity, positive predictive value (PVP), negative predictive value (PVN), and prevalence across all six years of screening to assess the validity of the Risk Factor Model.ResultsSubjects' overall mean caries prevalence across all six years was 66%. Average sensitivity across all six years was 79%; average specificity was 81%; average PVP was 89% and average PVN was 67%.ConclusionsOverall, the Risk Factor Model provided a relatively constant, valid measure of caries that could be used in conjunction with a comprehensive risk assessment in population-based screenings by school nurses/nurse practitioners, health educators, and physicians to guide them in assessing potential future caries risk for use in prevention and referral practices.

Clinical comparison of Fuji VII and a resin sealant in children at high and low risk of caries

“…In the present study, individual caries experience in the primary dentition (dmft<2 or dmft>5) was the criterion used to divide patients into groups at high or low risk of caries. These same categories have been used as benchmarks in other studies 22,31) . Our study demonstrates that Fuji VII is useful as a pit and fissure sealant for children and effectively prevents caries.…”

“…Individual caries risk was based on the baseline dmft index of each patient. Two categories of caries risk severity were considered according to Ditmyer et al 22) and Kneist et al 23) : a) children with no or one carious tooth (dmft<2) were included in the LR group; and b) children with dmft>5 were placed in the HR group. Children with dmft 2-5 were not included in the present study.…”

Caries risk assessment in young adults using Public Dental Service guidelines and the Cariogram—a comparative study

“…This has led to guidelines which aim to act as a framework for the categorization of risk level, treatment decisionmaking and determination of individual recall intervals. In general, multiple risk factors and indicators based on general health, diet, oral hygiene and past caries experience have been proposed, varying with the age group at which they are targeted [4][5][6]. For adults, the Public Dental Service (PDS) in the Skåne Region have adopted guidelines based on past and present caries, periodontal conditions, general risk and technical risk.…”

Uji sensitivitas dan spesifisitas perangkat lunak “Prediktor Karies Anak” (The sensitivity and specificity test of software for dental caries prediction in children)

“…31 Alat prediksi karies yang mempunya nilai sensitivitas, spesifisitas, NDP dan NDN 70-100% termasuk dalam katagori bagus sampai sangat bagus, sehingga dapat dikatakan mempunyai validitas yang tinggi. 32 Perlu dilakukan penelitian lebih lanjut dengan menggunakan populasi yang lebih luas. Selain itu perlu melakukan penelitian tentang ada atau tidaknya perubahan perilaku anak maupun orangtua setelah dilakukan pengukuran prediksi resiko terjadinya karies.…”
