RESUMEN
OBJECTIVE: This in vitro study characterized and monitored, by Optical Coherence Tomography (OCT) and Fourier Transformed Infrared Spectroscopy (FTIR), the effects of the association of acidulated phosphate fluoride gel (APF-gel) and Nd:YAG (neodymiun:yttrium-aluminum-garnet) laser, as sequencial treatments, in the prevention of incipient enamel caries lesions. METHODS: 120 human enamel samples were randomized into 3 groups (n = 40): APF-gel (1.23% F-, 4 min.); Laser+APF (Nd:YAG laser irradiation-0.6W, 84.9J/cm2, 10Hz, followed by APF-gel); and APF+Laser (APF-gel followed by laser irradiation). The samples were subjected to a 15-day pH-cycling, evaluated by OCT (quantification of optical attenuation coefficient-OAC) and FTIR (analysis of carbonate and phosphate content) before treatments, after treatments, and on the 5th, 10th and 15th days of pH-cycling. The statistical analysis was performed (α = 5%). RESULTS: The Optical Attenuation Coefficient (OAC) assessed by OCT increases with the progression of demineralization, and the Laser+APF presented the highest values of OAC in 10th and 15th days of pH-cycling. Nd:YAG decreased the carbonate content after treatment regardless of the application order of the APF-gel, while APF-gel did not interfere in the composition of enamel. The carbonate content was also changed in the first 5 days of the pH-cycling in all groups. CONCLUSION: Nd:YAG laser irradiation before or after the application of APF-gel did not influence the appearance of incipient caries lesions, showing no synergistic effect. Regardless of the application order of the APF-gel, laser irradiation reduces the carbonate content of the enamel, which also changes during the demineralization process. However, irradiation before the application of APF-gel increased the speed of progression of the lesions, which positively impacts public health as it can prevent caries disease, even in high risk individuals. OCT and FTIR are suitable for assessing this effect.

BACKGROUND: Given the increasing prevalence of primary tooth caries in Iran and the importance of providing evidence- and theory-based family-centered prevention programs, the present study is aimed at determining the family-centered social cognitive factors preventing deciduous tooth caries among children using the intervention mapping protocol. METHODS: This cross-sectional study was performed on 240 Iranian mothers in Ilam who were randomly selected to participate in the study. The data were collected using a self-designed questionnaire including items on demographic information and social cognitive constructs (knowledge, attitude, perceived severity, perceived benefits, perceived barriers, practice guidance, perceived self-efficacy, behavior intention, subjective norms, and social norms). The questionnaire was completed by mothers, and the data were analyzed by performing one-way analysis of variance and linear regression. RESULTS: The results obtained from linear regression analysis showed that perceived self-efficacy (B = 0.295, p < 0.001), perceived barriers (B = 0.084, p < 0.028), practice guidance (B = 0.774, p < 0.001), and social norms (B = 0.137, p < 0.020) accounted for 71% of the behavioral intention variance and were the most important predictors for preventing primary tooth caries among children. CONCLUSION: The findings suggest that perceived self-efficacy, perceived barriers, practice guidance, and social norms are essential for developing family-centered programs to prevent primary tooth caries in children.

Dental caries is a biofilm-mediated, dynamic disease with early onset. A balanced salivary microbiota is a foundation of oral health, while dysbiosis causes tooth decay. We compared the saliva microbiota profiles in children with and without caries. The study consisted of 617 children aged 9-12 years from the Finnish Health in Teens (Fin-HIT) study with available register data on oral health. Caries status was summarised based on Decayed, Missing, and Filled Teeth (DMFT) index in permanent dentition. The children were then classified into the following two groups: DMFT value ≥ 1 was considered as cavitated caries lesions (hereafter called 'caries') (n = 208) and DMFT = 0 as 'cavity free' (n = 409). Bacterial 16S rRNA gene (V3-V4 regions) was amplified using PCR and sequenced by Illumina HiSeq. The mean age (SD) of the children was 11.7 (0.4) years and 56% were girls. The children had relatively good dental health with mean DMFT of 0.86 (1.97). Since sex was the key determinant of microbiota composition (p = 0.014), we focused on sex-stratified analysis. Alpha diversity indexes did not differ between caries and cavity free groups in either sexes (Shannon: p = 0.40 and 0.58; Inverse Simpson: p = 0.51 and 0.60, in boys and girls, respectively); neither did the composition differ between the groups (p = 0.070 for boys and p = 0.230 for girls). At the genus level, Paludibacter and Labrenzia had higher abundances in the caries group compared to cavity free group in both sexes (p < 0.001). Taken together, there were minor differences in saliva microbiota between children with and without caries. Potential biomarkers of caries were the sugar metabolisers Paludibacter and Labrenzia. These bacteria presumably enhance salivary acidification, which contributes to progression of dental caries. The clinical relevance of our findings warrants further studies.

BACKGROUND: Early childhood dental caries (ECC), a serious public health problem lacks information on the association between ECC, risk factors and nutritional status among children in Tanzania. Therefore, this study aimed to determine the prevalence of ECC, risk factors and nutritional status among 3-5-year-old preschool children and to assess its correlation with the form, visible plaque scores in upper anterior teeth, total sugar exposure, anthropometric measures, and socio demographic attributes. METHODS: This cross-sectional study was conducted on 831 children registered in public preschools in Kisarawe District. Assessment of ECC used the WHO (2013) criteria and anthropometric measures used the WHO Child Growth Standards (2006). Structured questionnaires were completed by children's parents through an interview. Collected information on socio-demographic attributes including oral hygiene and sugar exposure to their children was analyzed. RESULTS: Only 459 children (55.2%) were recognized as caries-free. Dental caries experience in terms of decayed, missing and filled teeth (dmft) index was 2.51. Children with visible plaque were the majority (56.1%). The dmft score index was negatively and significantly associated with weight-for-age z-score [Coefficient: -0.11 (95% CI: -0.76, -0.11)] and positively significantly associated with visible plaque score index [Coefficient: 0.16 (95% CI: 0.18, 0.52)] and total sugar exposure [Coefficient: 0.19 (95% CI: 0.15, 0.38)] in the adjusted model. The prevalence of underweight was 4.2% [95% CI: (3.0-5.8)] and severe underweight was 0.2% [95% CI: (0.1-0.9)] while prevalence of stunting was 1.6% [95% CI: (0.9-2.7)] and severe stunting was 0.4% [95% CI: (0.1-1.1)]. CONCLUSION: This study demonstrated a significant negative relationship between ECC and children's anthropometric measures indicated by weight-for-age, and positive relationship with sugar exposure and poor oral hygiene indicated by visible plaque on upper anterior teeth. Controlling risk factors will reduce the occurrence of ECC thereby catering for a healthy population of well-nourished children.

BACKGROUND: Sugar-sweetened beverages (SSBs) have been associated with childhood caries; however, associations among lifelong beverage intakes and adolescent caries have received less attention. OBJECTIVE: To investigate associations between beverage intakes during childhood and adolescence and caries experience at 17 years of age, while adjusting for fluoride intakes and toothbrushing. DESIGN: Descriptive model analyses were conducted on data collected from a longitudinal birth cohort study. PARTICIPANTS/SETTING: Participants included Iowa Fluoride Study members (n = 318) recruited at birth between 1992 and 1995 with at least 6 beverage questionnaires completed from ages 1 to 17 years and a caries examination at age 17. EXPOSURE: Predictors included mean daily milk, juice (100% juice and juice drinks before age 9), SSB (including juice drinks after age 9), and water/sugar-free beverage (SFB) intakes; daily fluoride intakes; and daily toothbrushing frequencies for ages 1 to 17. MAIN OUTCOME MEASURES: The outcome was dental caries count at age 17, adjusted for the number of scored tooth surfaces (decayed and filled surfaces attack rate [DFSAR]). STATISTICAL ANALYSES PERFORMED: Univariable generalized linear models were fit for each predictor and the outcome DFSAR. Multivariable models assessed combined effects of beverage types, fluoride variables, toothbrushing, sex, and baseline socioeconomic status. RESULTS: Based on multivariable models, each 8 oz of additional daily juice and water/SFB decreased expected DFSAR by 53% (95% confidence interval [CI]: 17%-73%) and 29% (95% CI: 7%-46%), respectively, and 8 additional oz SSBs increased expected DFSAR by 42% (95% CI: 5%-92%), after adjustment for other beverage intakes, toothbrushing, total fluoride intake excluding SSB fluoride (non-SSB total fluoride), sex, and baseline socioeconomic status. Each additional daily toothbrushing event decreased expected DFSAR by 43% (95% CI: 14%-62%) after adjustment for beverage intakes, non-SSB total fluoride intake, sex, and baseline SES. CONCLUSIONS: Higher juice and water/SFB intakes and more toothbrushing were associated with lower caries at age 17, while higher SSB intakes were associated with higher caries.

Saliva contains a large number of proteins that play various crucial roles to maintain the oral health and tooth integrity. This oral fluid is proposed to be one of the most important host factors, serving as a special medium for monitoring aspects of microorganisms, diet and host susceptibility involved in the caries process. Extensive salivary proteomic and peptidomic studies have resulted in considerable advances in the field of biomarkers discovery for dental caries. These salivary biomarkers may be exploited for the prediction, diagnosis, prognosis and treatment of dental caries, many of which could also provide the potential templates for bioactive peptides used for the biomimetic management of dental caries, rather than repairing caries lesions with artificial materials. A comprehensive understanding of the biological function of salivary proteins as well as their derived biomimetic peptides with promising potential against dental caries has been long awaited. This review overviewed a collection of current literature and addressed the majority of different functions of salivary proteins and peptides with their potential as functional biomarkers for caries risk assessment and clinical prospects for the anti-caries application.

BACKGROUND: To assess the relationship of chosen salivary proteins and peptides levels with the occurrence of caries in children. METHODS: PubMed, MEDLINE and EMBASE databases from 2000 to 2018 were researched for original observational studies published in English. The risk of bias and quality of the included papers were assessed regarding the guidelines by Fowkes and Fulton. RESULTS: Twenty-two studies were included in the review, from which the issue of glycoproteins (including immunoglobulins), AMPs and salivary enzymes was discussed. The research involved primary dentition (13 papers), as well as mixed (7) and permanent dentition (5). Caries assessment included visual inspection, dmft/s and DMFT/S indexed; quantity of Streptococcus mutans and Lactobacillus spp. bacteria; and caries risk assessment. DISCUSSION: The results of studies regarding the connection between salivary peptides and proteins and caries development in children are promising; however, further investigations should be undertaken. The majority of studies included are case-control and cross-sectional; however, it is necessary to conduct more cohort studies with adequate follow-up prior to considering this as markers for caries risk assessment.

RESUMEN: La Caries Temprana de la Infancia (CTI) es una forma de caries dental agresiva que afecta a niños, y en el último reporte nacional reveló una prevalencia de caries del 50 % en niños de 4 años de edad de la Región Metropolitana de Santiago (Soto et al., 2007). El objetivo de este estudio es validar un cuestionario que permita recolectar información relacionada con diversos factores de riesgo de caries en niños preescolares. Para la validación del cuestionario se determinó la validez de convergencia y discriminación, la consistencia interna y la confiabilidad test retest del instrumento en dos muestras independientes. Se aplicó el instrumento al cuidador principal de 118 preescolares entre 24 a 71 meses de edad, que asisten a jardines infantiles de dependencia particular (bajo riesgo de caries) y la Fundación INTEGRA (alto riesgo de caries) en la Región Metropolitana de Santiago, Chile. Se realizaron exámenes clínicos dentales por 2 odontólogos calibrados utilizando en el criterio OMS e ICDAS II. Se estimó un modelo de regresión logística y se evalúo la capacidad de discriminación del puntaje a través de una curva ROC. El cuestionario mostró una validez de discriminación de 0,95 entre ambos grupos y de la pregunta global 0,61 y una consistencia interna del cuestionario de 0,72. En la validez de convergencia se encontró que no existe asociación estadísticamente significativa entre el puntaje del cuestionario y la pregunta global dicotomizada (OD) 1,061. No obstante, se evidenció que si existe asociación estadísticamente significativa entre el puntaje del cuestionario y el grupo riesgo de caries (bajo y alto) (OD) 1,961. La estabilidad temporal mediante comparaciones Test - Retest calculado con el índice de Kappa osciló entre 0,37 a 1. Por lo tanto, se puede concluir que el presente cuestionario es un instrumento válido para discriminar riesgo de caries, permitiendo un mejor análisis de los determinantes de la caries dental en la población preescolar chilena.
ABSTRACT: Early Childhood Caries (ECC) is an aggressive form of tooth decay, and the last national unpublished reports reveal a caries prevalence of 50 % at 4 years of age in children, in the Santiago Metropolitan Region (Soto et al., 2007). The objective of this study is to validate a questionnaire that allows the collection of information related to several caries risk factors in preschoolchildren. For the validation of the questionnaire, the convergence and discrimination validity, the internal consistency and the retest, test reliability of the instrument were determined in two independent samples. The instrument was applied to the main caregiver of 118 preschoolers between 24 and 71 months of age, who attend private childcare centers (low caries risk) and the INTEGRA Foundation childcare (high caries risk) in the Metropolitan Region of Santiago, Chile. Dental clinical examinations were performed by two calibrated dentists using the OMS and ICDAS II criteria. A logistic regression model was estimated and the ability to discriminate the score through an ROC curve was evaluated. The questionnaire showed a validity of discrimination of 0.95 between both groups and of the global question 0.61 and an internal consistency of the questionnaire of 0.72. In the convergence validity, it was found that there is no statistically significant association between the questionnaire score and the dichotomized global question (RE) 1.061. However, it was evidenced that there is a statistically significant association between the questionnaire score and the caries risk group (low and high) (OD) 1.961. Temporal stability by means of Test - Retest comparisons calculated with the Kappa index ranged from 0.37 to 1. Therefore, it can be concluded that the present questionnaire is a valid instrument for discriminating caries risk, allowing a better analysis of the determinants of dental caries in the Chilean preschool population.

In recent years, unprecedented gains in the understanding of the biology and mechanisms underlying human health and disease have been made. In the domain of oral health, although much remains to be learned, the complex interactions between different systems in play have begun to unravel: host genome, oral microbiome with its transcriptome, proteome and metabolome, and more distal influences, including relevant behaviors and environmental exposures. A reasonable expectation is that this emerging body of knowledge can help improve the oral health and optimize care for individuals and populations. These goals are articulated by the National Institutes of Health as "precision medicine" and the elimination of health disparities. Key processes in these efforts are the discovery of causal factors or mechanistic pathways and the identification of individuals or population segments that are most likely to develop (any or severe forms of) oral disease. This article critically reviews the fundamental concepts of risk assessment and outcome prediction, as they relate to early childhood caries (ECC)-a common complex disease with significant negative impacts on children, their families, and the health system. The article highlights recent work and advances in methods available to estimate caries risk and derive person-level caries propensities. It further discusses the reasons for their limited utility in predicting individual ECC outcomes and informing clinical decision making. Critical issues identified include the misconception of defining dental caries as a tooth or surface-level condition versus a person-level disease; the fallacy of applying population-level parameters to individuals, termed privatization of risk; and the inadequacy of using frequentist versus Bayesian modeling approaches to derive individual disease propensity estimates. The article concludes with the notion that accurate caries risk assessment at the population level and "precision dentistry" at the person level are both desirable and achievable but must be based on high-quality longitudinal data and rigorous methodology.

Older adults are retaining an increasing number of natural teeth, and nearly half of all individuals aged 75 and older have experienced root caries. Root caries is a major cause of tooth loss in older adults, and tooth loss is the most significant negative impact on oral health-related quality of life for the elderly. The need for improved preventive efforts and treatment strategies for this population is acute.

AIM: An investigation was conducted in a population of paediatric patients with a high risk of caries in order to assess the association between caries history (CH) and the number of early carious lesions (ECLs) and the frequency and timing of cariogenic food and beverage intake, sugar-containing medication, the frequency and efficacy of tooth brushing, and the use of topical fluorides. MATERIALS AND METHODS: Study design: descriptive study. One hundred children aged 6-15 years with≥ ECL of a permanent tooth and not enrolled in any dental health educational or preventive programme were selected. For diagnosis it was used an explorer according to the ICDAS II criteria. The participants completed a closed-list questionnaire on the frequency and timing of cariogenic food intake. RESULTS: There was a nonsignificant tendency to present more ECLs and a greater CH among patients who consumed cariogenic foods and beverages. A significant relationship (p<0.05) was observed between cariogenic beverages and the number of ECL or CH. Using the number of ECLs as dependent variable, regular fluoridated rinses (p=0.003), frequent sugar-containing medication (p=0.007), and cariogenic beverage consumption (p=0.024) were identified as explanatory parameters in the linear regression model. STATISTICS: The Student t-test was used to compare ECL and CH with dietetic factors, fluoridated rinses, sugar- containing medicines, and the frequency and efficacy of tooth brushing. Linear regression analysis correlated the number of ECLs to the mentioned explanatory variables. CONCLUSION: The frequent consumption of sugary beverages and medications, and failure to regularly use fluoridated rinses, were positively correlated to an increased number of ECLs in patients with a high prevalence of caries.

PURPOSE: The purpose of this paper was to determine if number and cost of dental treatments in high caries-risk children differs in children with early dental intervention compared to children with later intervention. METHODS: Billing data from children age zero to seven years old, whose first dental visit was between January 1, 2004 and December 31, 2004, were collected from 20 corporate treatment centers serving children from lower socioeconomic status backgrounds. Data included age at first visit, dental treatment codes, and associated costs for eight years after the first dental visit. Treatment included restorations, crowns, pulpotomies, and extractions. First visit age was categorized into early starters (younger than four years old) and late starters (four years of age or older). Linear regression with cluster adjustment for clinic determined a difference in costs and dental treatments by early and late starters. RESULTS: Of 42,532 subjects, 17,040 (40 percent) were early starters and 25,492 (60 percent) were late starters. There were 3.58 more dental procedures performed on late starters, over eight years of follow-up, than on early starters (P<.001). Late starters spent $360 more over eight years of follow-up than early starters (P<.001). CONCLUSION: In this study, number of procedures performed were fewer and cost of treatment less for children seen earlier versus later.

PURPOSE: To evaluate the 10-year durability of a nanohybrid resin composite in Class II restorations in a randomized controlled intraindividual comparison with its conventional hybrid resin composite predecessor. MATERIALS AND METHODS: Each of 52 participants received at least two Class II restorations that were as similar as possible. The cavities were chosen at random to be restored with a nanohybrid resin composite (Excite/Tetric EvoCeram (TEC); n=61) and a conventional hybrid (Excite/Tetric Ceram (TC); n=61). The restorations were evaluated with slightly modified USPHS criteria at baseline and then annually for 10 years. The overall performance of the experimental restorations was tested after intra-individual comparison and their ranking was tested using Friedman's two-way ANOVA. The level of significance was set at 5%. RESULTS: Four patient drop-outs with 8 restorations (4TEC, 4TC) were registered during the follow-up. A prediction of the caries risk showed that 16 of the evaluated 52 patients were considered as high risk patients. In total, 22 restorations, 11 TEC (3 premolars, 8 molars) and 11 TC (3 premolars, 8 molars) restorations failed during the 10 years. The main reason for failure was secondary caries (50%). 63% of the recurrent caries lesions were found in high caries risk participants. The overall success rate at 10 years was 80.7%, with an annual failure rate of 1.9%. No statistically significant difference was found in the overall survival rate between the two investigated resin composites. CONCLUSION: The nanohybrid and the conventional hybrid resin composite showed good clinical effectiveness in extensive Class II restorations during the 10-year study.

OBJECTIVE: The objectives of this research were to: (1) quantify the discordance between the caries lesion depth at which dentists restored initial lesions during a clinical study ("actual depth") and the lesion depth that they reported during a hypothetical clinical scenario ("reported depth"); (2) test the hypothesis that certain practitioner, practice, patient, and caries lesion characteristics are significantly associated with this discordance. METHODS: Practitioner-investigators who perform restorative dentistry in their practices completed an enrollment questionnaire and participated in 2 consecutive studies on caries diagnosis and treatment. The first study was a survey asking about caries treatment. The second study collected data on restorations placed in routine clinical practice due to caries in patients over 19 years of age on occlusal surfaces only or proximal surfaces only. We report results on 2,691 restorations placed by 205 dentists in 1,930 patients with complete data. RESULTS: Discordance between actual depth and reported depth occurred in only about 2% of the restorations done due to proximal caries, but about 49% of the restorations done due to occlusal caries. Practice type, restorative material used and the diagnostic methods used were significantly associated with discordance. CONCLUSION: Dentists frequently restored occlusal caries at a shallower depth as compared to their reported depth, but the discordance was very small for proximal lesions. Discordance for occlusal caries was more common when radiographs were not taken or if a resin restoration was placed.

BACKGROUND: The Public Dental Service of Västerbotten County (Sweden) recommends using population-based prevention strategies combined with an individual strategy for high-risk patients to manage caries. To facilitate this management strategy, all patients are evaluated for their risk of developing caries in the coming year using defined criteria. Using caries risk scoring over a seven-year period, the present study evaluates prophylactic measures, caries development, and non-operative treatments in adult patients. METHODS: From all adult patients (25-65 years; n = 76 320) scored with a high caries risk in 2005 (baseline) and with a dental visit in 2011, 200 subjects were randomly selected. In addition, an equally sized control group with a no/low caries risk was selected. Information concerning dental status, counselling, treatments, visits, and costs were retrieved from dental records. RESULTS: Over the seven-year study period, subjects with high caries risk had significantly higher caries incidence in spite of shorter recall intervals, more dental appointments, and higher costs for dental care than subjects with no/low caries risk. Non-operative measures, such as additional fluoride and individual counselling on diet at baseline (2005), was higher in the high caries risk group, whereas information about basic prophylaxis and counselling on oral hygiene showed only small differences. The frequency of non-operative measures given during the seven-year study period to patients in the high caries risk group is considered to be remarkably low and improvement, determined as reclassification from high to no/low caries risk from 2005 to 2011, was seen in only 13% of the participants. CONCLUSIONS: This study formulated two major conclusions. First, adult patients with high or no/low caries represent different populations, that each contain distinct subpopulations, those who improve/impair or maintained their caries risk and disease progression. These groups need different strategies in disease treatment. Second, preventive measures and non-operative treatments were associated with improvements in caries risk and maintenance, but the extent to which such treatments were given to high caries risk subjects was unacceptably low. Improved adherence to the guidelines for caries treatment may reduce caries risk, visits to dental clinics, and costs for the patients.

Pits and fissures on the occlusal surfaces of posterior teeth are sites affected commonly by demineralisation caused by the caries process. Clinicians face daily challenges in detecting these lesions, accurately diagnosing their activity and choosing from a range of management options. Traditionally, the detection of an active (or potentially active) occlusal lesion invariably resulted in the preparation of a standardised occlusal cavity, often extending beyond the confines of diseased tissue, followed by the insertion of a direct restorative material, most commonly dental amalgam. The overwhelming weight of contemporary evidence now favours minimally invasive (MI) operative management when required (usually after non-operative prevention has failed), and a wide range of equipment, materials and operative techniques is available to help operators to preserve the maximum amount of healthy/repairable tooth tissue and to allow restoration with more biologically respectful, tooth-preserving materials. This paper aims to provide clinicians with practical guidance in the prevention, early detection, predictable diagnosis and minimally invasive management of early occlusal carious lesions.

PURPOSE: Microbiological methods that accurately identify caries-susceptible children may enhance caries control and assist treatment planning. This study's purpose was to evaluate the usefulness of two microbiological indicators (mutans streptococci [MS] and lactobacilli [LB] levels), singly and in combination, for predicting early childhood caries (ECC) and their contributions in multifactorial modeling. METHODS: A total of 1,782 randomly selected three- to five-year-olds were recruited and underwent oral examination and microbiological tests using commercially available diagnostic kits. A questionnaire was completed by their parents. After 12 months, the caries increment in 1,576 (â¼88 percent) children was assessed. RESULTS: Caries risk increased with the MS and LB levels but plateaued above the LB level of 10(5) CFU/ml saliva. MS, LB, and combined MS+LB models predicted one-year caries increment (Δdmft>0) with a sensitivity/specificity of 79 percent/67 percent, 51 percent/89 percent, and 66 percent/85 percent, respectively. Sensitivity/specificity reached 80 percent/80 percent when baseline caries experience ("past caries") was added to the MS+LB model and up to 85 percent/80 percent and 81 percent/85 percent when psychosociobehavioral factors and oral hygiene status were added to the MS+LB model, without and with "past caries," respectively. CONCLUSIONS: The combined "mutans streptococci+lactobacilli+past caries" model is useful for identifying at-risk children. Incorporating MS and LB into a biopsychosociobehavioral model slightly improved the prediction, even without "past caries".

OBJECTIVES: To evaluate the effect of biannual fluoride varnish applications in preschool children as an adjunct to school-based oral health promotion and supervised tooth brushing with 1000ppm fluoride toothpaste. METHODS: 424 preschool children, 2-5 year of age, from 10 different pre schools in Athens were invited to this double-blind randomized controlled trial and 328 children completed the 2-year programme. All children received oral health education with hygiene instructions twice yearly and attended supervised tooth brushing once daily. The test group was treated with fluoride varnish (0.9% diflurosilane) biannually while the control group had placebo applications. The primary endpoints were caries prevalence and increment; secondary outcomes were gingival health, mutans streptococci growth and salivary buffer capacity. RESULTS: The groups were balanced at baseline and no significant differences in caries prevalence or increment were displayed between the groups after 1 and 2 years, respectively. There was a reduced number of new pre-cavitated enamel lesions during the second year of the study (p=0.05) but the decrease was not statistically significant. The secondary endpoints were unaffected by the varnish treatments. CONCLUSIONS: Under the present conditions, biannual fluoride varnish applications in preschool children did not show significant caries-preventive benefits when provided as an adjunct to school-based supervised tooth brushing with 1000ppm fluoride toothpaste. CLINICAL SIGNIFICANCE: In community based, caries prevention programmes, for high caries risk preschool children, a fluoride varnish may add little to caries prevention, when 1000ppm fluoride toothpaste is used daily.
