OBJECTIVE: Caries risk assessment tools operate on the subject level. The aim of the study is to create new caries risk assessment models that functions on the tooth and surface level to assess the risk of caries of single teeth and surfaces. METHODS: Secondary data from the Dental Longitudinal Study was used to evaluate caries symmetry. Teeth were grouped into posterior and anterior teeth. Surfaces were grouped into fissured, proximal, and facial and lingual surfaces. The prediction of future caries on a tooth or a surface by the current caries on a bilateral or adjacent tooth or surface was evaluated. Additional general and oral caries risk factors on teeth and surfaces were adopted from the American Dental Association caries risk assessment tool. Caries on bilateral and/or adjacent teeth or surfaces were augmented with significant oral clinical caries predictor to build the caries risk assessment tools for teeth and surfaces. The models were validated by calculating sensitivities and specificities. RESULTS: 495 subjects with baseline and three year follow up data were included in the study. Caries prevalence and incidence was symmetrical (right and left) on the population level. On the individual level, caries incidence was symmetrical (right and left) and also tends to affect adjacent teeth or surfaces. Baseline caries on bilateral and adjacent teeth and surfaces was predictive of caries at follow up in all groups of teeth and surfaces except posterior teeth. Local oral caries risk factors like visible plaque, interproximal restorations, and xerostomia significantly predicted caries on single teeth and surfaces. Tools of caries risk assessment for anterior teeth and the three groups of surfaces were built. The sensitivities of these tools ranged between 67.33% to 85.51 %, specificities ranged between 38.40 % to 66.11%, and the overall accuracies ranged between 41.95% to 66.27%. CONCLUSION: Dental caries is a symmetrical disease affecting the right and left sides of the mouth equally. Past caries experience is significant in predicting future caries. New models were built to assess caries risk for anterior teeth, fissured surfaces, proximal surfaces, and facial and lingual surfaces with acceptable accuracy. / 2018-09-28T00:00:00Z

Dental caries is a very common chronic infectious disease that is preventable and related to dental behaviours. The objective of this study was to develop a parental questionnaire to predict the child’s caries risk without professional evaluation and assess if risk factors worked together and if behaviours changed over time. At baseline, a survey and examination for caries were administered to 100 subjects aged 1 to 3 years old in Winnipeg, Manitoba. Six months later the same survey and examination were administered. Statistical analysis included logistic regression, Pearson Chi-squared, McNemar’s, Fisher’s exact tests and paired T-tests. The main finding was this survey could not predict future caries risk. Parents’ reports of visible cavities/fillings in their child predicted caries. Few risk factors changed significantly over time. A change in developmental delay corresponded to a change in caries. Overall, caries risk was found to be complex and requires further investigation.

Purpose: This was a pilot study to assess the impact of a preventive strategy following full-mouth dental rehabilitation (FMDR) under general anesthesia in children with early childhood dental caries. Methods: Sixty-six patients completed FMDR and were included in the analysis. At the consultation visit, caries risk assessment (CRA) and dental exam information were recorded, and caregivers completed an oral health knowledge (OHK) questionnaire. Patients returned for a post-surgery and recall visit. Caregivers received oral hygiene instructions in a motivational-interviewing style. Results:At the consultation visit all patients were high risk. At the post-surgery visit, only 47% remained high risk (chi-square P Conclusions: Preliminary data demonstrates that the preventive strategy is effective in reducing CRA level in children following FMDR.

Oitenta e um alunos de 6a a 8a séries da rede pública escolar de Piracicaba foram selecionados e se submeteram a um exame clínico odontológico - feito por um pesquisador clínico com experiência no diagnóstico e tratamento de pacientes de alta atividade de cárie - e a um exame salivar, feito com o produto CARITEST SM®, a partir de um mesmo lote de fabricação. Utilizando-se a estatística kappa, a reprodutibilidade do teste microbiológico foi verificada através da concordância interexaminador, na avaliação dos resultados microbiológicos de maneira independente. A validade foi verificada, através da sensibilidade e especificidade, comparando-se os resultados microbiológicos com o critério de validação ("gold standard") da pesquisa. Os valores de kappa, k=0,55 e k=0,78, representaram, respectivamente, uma concordância interexaminador regular considerando a avaliação segundo 6 escores propostos pelo fabricante, e uma concordância boa para a classificação segundo alta e baixa contagem microbiológica,- dada pelo agrupamento dos escores. O valor para a sensibilidade foi de 0,59 e para a especificidade foi de 0,85, mostrando que o teste foi mais específico do que sensível, identificando melhor os indivíduos de baixo risco de cárie. Esse teste microbiológico pode ser considerado um bom auxiliar na avaliação do risco de cárie, porém não é o único fator preditivo a ser avaliado, frente ao caráter multifatorial da doença / Abstract: The aim of this study was to evaluate the efficacy of a microbiological test for estimation of mutans streptococci levels in caries risk assessment. Eighty-one volunteers from 6th up to 8th grades from Piracicaba's public schools were assessed for dental caries. A researcher with great skills in examining and treating patients with high caries activity performed the examinations. The students were then submitted to a salivary test, CARITEST SM® (from the same batch number). Kappa statistics (K) was applied to verify the repeatibility of the simplified test checked through interexaminer agreement, in the classification of the microbiological tests, independently and blind. The validity of the test was verified according to sensibility and specificity, comparing the microbiological results with the gold standard for caries risk. A fair agreement was verified when the examiners classified according to 6 scores (K=0.55) and a good agreement when they classified according to high or low density of unit colonies formation (K=0.78). The sensibility was 0.59 and the specificity was 0.85, showing that there was a moderate ability of the test to identify the subjects with high caries risk and a substantial ability to identify the group of low caries risk. The microbiological test represents an aid for cariesrisk assessment, but it is not the only criteria to be used for caries risk diagnosis, considering the multifactorial character of the disease / Mestrado / Dentística / Mestre em Clínica Odontológica

Aim: The aim of the study was to compile scientific studies that studied the reliability of the caries risk assessment instruments (CAMBRA, Cariogram and R2) and their capacity to predict future caries development in children and adolescents. Method: The study is a general literature study based on scientific articles obtained from the databases Dentistry & Oral Sciences source (DOSS), PUBMED, CINAHL, SwePub and SveMed+. The articles were selected according to inclusion-/exclusion criteria. The included studies were reviewed with modified review template to present studies of strong value. The result is based on a total of 17 scientific articles that respond to the study's purpose and questions. Result: Caries risk assessment instrument is a useful tool in dental care, as it facilitates work with the risk grouping of patients. However, there is a need for further development of the various instruments in order for these to be considered fully reliable. Conclusion: The common feature of the three caries risk assessment instruments is that these should be reviewed and further developed in order to achieve full reliability. / Syfte: Syftet med litteraturstudien var att sammanställa vetenskapliga studier som studerat tillförlitligheten av kariesriskbedömningsinstrumenten (CAMBRA, Cariogram och R2) och deras kapacitet att förutse framtida kariesutveckling hos barn och ungdomar. Metod: Studien är en allmän litteraturstudie baserad på vetenskapliga artiklar hämtade från databaserna Dentistry & Oral Sciences source (DOSS), PUBMED, CINAHL, SwePub och SveMed+. Artiklarna har valts ut med hjälp av inklusion- och exklutionskriterier. De inkluderade artiklarna granskades med hjälp av en modifierad kvalitetsgranskningsmall för att fastställa att studierna vara av hög validitet, reliabilitet och kvalitet. Resultatet baseras på totalt 17 vetenskapliga artiklar som svarar på studiens syfte och frågeställning. Resultat: Användning av de tre kariesriskbedömningsinstrumenten är ett bra hjälpmedel inom tandvården, då det underlättar vid riskgruppering av patienter. Dock finns ett stort behov av vidareutveckling av de olika instrumenten för att dessa ska anses fullt tillförlitliga. Slutsats: Gemensamt för de tre kariesriskbedömningsinstrumenten är att dessa bör granskas och vidareutvecklas för att full tillförlitlighet ska kunna uppnås.
