Abstract
PURPOSE To investigate the effect of pre-cured and co-cured flowable composite liner on fracture strength and microleakage of primary anterior teeth with extended composite resin restorations. METHODS In the current in vitro experimental study, the crowns of 54 extracted primary canine teeth were cut 1 mm above the CEJ, and a pulpectomy procedure was performed. The samples were randomly divided into three groups to restore the coronal part up to 4 mm above the CEJ. In group 1, the samples were built up with Filtek Z250 packable composite resin. In group 2 (pre-cure), first, 1 mm of Filtek Z350 XT flowable liner was applied to the sample, and after curing, the restoration process continued using packable composite resin. In group 3 (co-cure), the flowable composite liner was cured while the first layer of packable composite resin was applied; then, the same restorative procedure similar to the other groups was followed. The samples' cross-sectional area in the fracture strength test was calculated by AutoCAD software. Subsequently, the samples were subjected to a force in a universal testing machine. The samples related to the microleakage experiment were cut vertically, and then, the dye penetration percentage (10% methylene blue) was measured under a stereomicroscope. ANOVA was used to analyze the data. RESULTS Mean fracture strength in group 2 was significantly higher than in group 1 (P = 0.016). The microleakage mean in group 3 was significantly lower than in groups 1 (P = 0.000) and 2 (P = 0.026). CONCLUSION The flowable composite liner and its relevant separate curing increased the fracture strength of composite resin restorations. However, less microleakage was reported in the group where the liner was applied as a co-cure.

Abstract
The primary aim of this study was to determine the prevalence of dental caries and its association with infant feeding and oral health-related behavior in Japanese children between the ages of 18 months and 3 years. A total of 387 infants were initially examined at the age of 18 months (or 19 months in some cases) and then again at 3 years (or at 3 years 1 month in some cases). The primary objective was to identify factors contributing to the prevalence of caries in children aged 18 months. The secondary objective was to follow up children with no caries at the age of 18 months to seek potential correlations between background factors and the increment of caries by the age of 3 years. In an adjusted multivariate logistic regression model, children who continued breastfeeding were approximately 7 times more likely to have dental caries at 18 months of age than those who did not. Infants brought in for an oral examination and consultation at around 12 months of age were less likely to develop dental caries at 18 months of age than those who were not. Multivariate logistic regression analysis revealed that infants who did not receive a dental check-up at 12 months of age showed a significantly higher incidence of dental caries at 3 years of age. The present results suggest that prolonged breastfeeding is a risk factor for early childhood caries at 18 months of age, and that infants in whom a regular oral care program is implemented from the age of 12 months are less likely to develop early childhood caries at 18 months or 3 years.

Abstract
In developing countries, the prevalence of dental caries in children remains high, which means that implementing a simple and convenient classification is critical. The classification needs to be evidence-based and needs to reflect tooth-level information. In this study, the prevalence of dental caries in the primary dentition of 352 Myanmar school children at the ages of 5, 6, and 7 was analyzed at the tooth level to clarify the underlying data structure of the patterns of dental caries in the population. Ninety-three percent of subjects had caries in primary dentition and the mean number of decayed teeth in primary dentition was 7.54 ± 4.82. Based on the item response theory analysis, mixed-effect modeling, and Bayesian network analysis, we proposed the following classification: Group 1: No dental caries; Group 2: Dental caries in molar teeth or dental caries in maxillary anterior teeth; Group 3: Dental caries in both molar and maxillary anterior teeth; Group 4: Dental carries in mandibular anterior teeth. Dental caries (dmft) in the groups was different between groups. The results of characteristics of tooth-level information and classification presented in this study may be a useful instrument for the analysis of the data of dental caries prevalence in primary dentition.

Abstract
OBJECTIVE The purpose of this study was to describe the oral health, oral hygiene, and oral health habits of Kuwaiti infants and toddlers. SUBJECTS AND METHODS This cross-sectional study of a convenience sample included 336 infants and toddlers (156 females and 180 males). The teeth of the infants and toddlers were examined using a mirror and a light source. Oral hygiene was recorded, and then all teeth were cleaned with gauze and examined for caries. Parents were interviewed regarding their children's feeding habits, brushing or tooth cleaning, and night feeding. The evaluation criteria for caries were sound teeth, noncavitated lesions, cavitated lesions, filled teeth, and missing teeth. RESULTS The mean age was 11.1 ± 2.4 months (range 2-23). Of the 336 subjects, 247 (73%) had good oral hygiene, 64 (19%) had parents who brushed or cleaned their infants' and toddlers' teeth; 288 (86%) were bottle-fed, and 290 (86%) were also night fed. The mean number of teeth upon examination was 4.6 ± 2.7 (range 2-8). Three percent of the infants and toddlers had caries. Cavitated lesions were present in 6 patients (1.8%), while 4 (1.2%) had noncavitated lesions. The mean d1d2t (caries teeth: noncavitated lesions and cavitated lesions) was 0.03 ± 0.3, and the mean d1d2s (carious surfaces) was 0.07 ± 0.5. CONCLUSION The caries prevalence and severity was low in infants and toddlers. However, poor oral health practices and habits as well as unhealthy feeding practices that could affect the future caries prevalence were noted.

Abstract
OBJECTIVES Assess pediatric providers' ability to identify visible plaque on children's teeth. METHODS Pediatric providers (residents, nurse practitioners, and attendings) conducting well-child care on 15-month to 5-year-olds in an academic practice examined children's maxillary incisors for visible plaque (recorded yes/no). A dental hygienist then examined the children and recorded the degree of visible plaque present. RESULTS The children's mean age was 34 months (±15 months), and 50% had visible plaque. Providers (n = 28) identified visible plaque on 39% of children (n = 118), with 55% sensitivity and 80% specificity, and agreement with hygienist measured as a κ score was 0.34. Subgroup analyses (based on provider training level, exam experience, child age, and plaque scores) did not appreciably improve sensitivity, specificity, positive predictive value, negative predictive value, or κ scores. CONCLUSIONS Visible plaque exams performed during well-child care may not be accurate. To comply with caries-risk assessment guidelines, providers require further education in oral exams.

Abstract
OBJECTIVES Fluoride varnish (FV) is efficacious in caries prevention although its effects among different tooth surfaces are poorly understood. This study sought to determine the extent to which caries-preventive effects of a community intervention that included FV application among preschool-aged children varied according to primary tooth anatomy and baseline tooth pathology. METHODS Secondary analysis was undertaken of data from a community-randomized controlled trial among 543 3- to 5-year-old Aboriginal children in 30 Northern Territory Australian communities. Children in intervention communities received community health promotion and FV application once every 6 months. Net caries (d(3)mfs) risk and 95% confidence limits (CL) were estimated for the control and intervention arms, and stratified according to tooth anatomy/location and baseline pathology (sound, enamel opacity, hypoplastic defect or precavitated carious lesion). The intervention's efficacy was quantified using generalized estimating equation modeling accounting for study design and clustering. The assumption of efficacy homogeneity was tested using a Wald χ(2) test with a p < 0.2 criterion and post hoc pairwise comparisons. RESULTS The intervention resulted in a 25% reduction (relative risk, RR = 0.75; 95% CL = 0.71, 0.80) in the 2-year surface-level caries risk. There was substantial heterogeneity in FV efficacy by baseline surface pathology: RRs were 0.73 for sound, 0.77 for opaque, 0.90 for precavitated, and 0.92 for hypoplastic surfaces. Among sound surfaces, maxillary anterior facials received significantly more benefit (RR = 0.62) compared to pits and fissures (RR = 0.78). CONCLUSION The intervention had greatest efficacy on surfaces that were sound at baseline. Among those sound surfaces, maxillary anterior facials received most caries-preventive benefit.

Abstract
OBJECTIVES Dental caries of the permanent dentition is a multifactorial disease resulting from the complex interplay of endogenous and environmental risk factors. The disease is not easily quantitated due to the innumerable possible combinations of carious lesions across individual tooth surfaces of the permanent dentition. Global measures of decay, such as the DMFS index (which was developed for surveillance applications), may not be optimal for studying the epidemiology of dental caries because they ignore the distinct patterns of decay across the dentition. We hypothesize that specific risk factors may manifest their effects on specific tooth surfaces leading to patterns of decay that can be identified and studied. In this study, we utilized two statistical methods of extracting patterns of decay from surface-level caries data to create novel phenotypes with which to study the risk factors affecting dental caries. METHODS Intra-oral dental examinations were performed on 1068 participants aged 18-75 years to assess dental caries. The 128 tooth surfaces of the permanent dentition were scored as carious or not and used as input for principal components analysis (PCA) and factor analysis (FA), two methods of identifying underlying patterns without a priori knowledge of the patterns. Demographic (age, sex, birth year, race/ethnicity, and educational attainment), anthropometric (height, body mass index, waist circumference), endogenous (saliva flow), and environmental (tooth brushing frequency, home water source, and home water fluoride) risk factors were tested for association with the caries patterns identified by PCA and FA, as well as DMFS, for comparison. The ten strongest patterns (i.e. those that explain the most variation in the data set) extracted by PCA and FA were considered. RESULTS The three strongest patterns identified by PCA reflected (i) global extent of decay (i.e. comparable to DMFS index), (ii) pit and fissure surface caries and (iii) smooth surface caries, respectively. The two strongest patterns identified by FA corresponded to (i) pit and fissure surface caries and (ii) maxillary incisor caries. Age and birth year were significantly associated with several patterns of decay, including global decay/DMFS index. Sex, race, educational attainment, and tooth brushing were each associated with specific patterns of decay, but not with global decay/DMFS index. CONCLUSIONS Taken together, these results support the notion that caries experience is separable into patterns attributable to distinct risk factors. This study demonstrates the utility of such novel caries patterns as new outcomes for exploring the complex, multifactorial nature of dental caries.

Abstract
Background Dental caries is a major public health problem in many countries. Since the last territority-wide dental survey of Hong Kong preschool children was conducted in 2001, a survey to update the information is necessary. This study aimed to describe the dental caries experience of preschool children in Hong Kong and factors affecting their dental caries status. Methods A stratified random sample of children from seven kindergartens in Hong Kong was surveyed in 2009. Ethical approval from IRB and parental consent was obtained. Clinical examinations of the children were performed by two calibrated examiners using disposable dental mirrors, an intra-oral LED light and ball-ended periodontal probes. A questionnaire to investigate possible explanatory factors for caries status was completed by the children’s parents. Caries experience was recorded using the dmft index. Multifactor-ANOVA was used to study the relationship between dental caries experience, and the background and oral health-related behaviours of the children. Results Seven hundred children (53% boys), mean age 5.3 ± 0.7 years were examined. The mean dmft score of the surveyed children was 2.2 and 51% of them had no caries experience (dmft = 0). Most (>95%) of the decayed teeth were untreated. Statistically significant correlations were found between dental caries experience of the children and their oral health-related habits, family income, parental education level and parental dental knowledge. Conclusions Early childhood dental caries was prevalent among the preschool children in Hong Kong. Their caries experience was associated with their oral health-related behaviours, socio-economic background, and parental education and dental knowledge.

Abstract
Background Dental caries is the result of a complex interplay among environmental, behavioral, and genetic factors, with distinct patterns of decay likely due to specific etiologies. Therefore, global measures of decay, such as the DMFS index, may not be optimal for identifying risk factors that manifest as specific decay patterns, especially if the risk factors such as genetic susceptibility loci have small individual effects. We used two methods to extract patterns of decay from surface-level caries data in order to generate novel phenotypes with which to explore the genetic regulation of caries. Methods The 128 tooth surfaces of the permanent dentition were scored as carious or not by intra-oral examination for 1,068 participants aged 18 to 75 years from 664 biological families. Principal components analysis (PCA) and factor analysis (FA), two methods of identifying underlying patterns without a priori surface classifications, were applied to our data. Results The three strongest caries patterns identified by PCA recaptured variation represented by DMFS index (correlation, r = 0.97), pit and fissure surface caries (r = 0.95), and smooth surface caries (r = 0.89). However, together, these three patterns explained only 37% of the variability in the data, indicating that a priori caries measures are insufficient for fully quantifying caries variation. In comparison, the first pattern identified by FA was strongly correlated with pit and fissure surface caries (r = 0.81), but other identified patterns, including a second pattern representing caries of the maxillary incisors, were not representative of any previously defined caries indices. Some patterns identified by PCA and FA were heritable (h2 = 30-65%, p = 0.043-0.006), whereas other patterns were not, indicating both genetic and non-genetic etiologies of individual decay patterns. Conclusions This study demonstrates the use of decay patterns as novel phenotypes to assist in understanding the multifactorial nature of dental caries.

Abstract
OBJECTIVES The aims of this study were to compare prevalence of early childhood caries (ECC) in 1- to 3-year-old children seeing primary-care pediatricians at two urban medical centers in Boston to the prevalence of ECC in similarly aged US children surveyed as part of the Third National Health and Nutrition Examination Survey (NHANES III) and to assess risk factors for ECC among this cohort of children compared with risk factors among similarly aged US children. METHODS Characteristics of 787 1- to 3-year-old children from two urban Boston medical centers were compared with those of 3,644 similarly aged US children surveyed as part of NHANES III. Demographic and social characteristics and ECC prevalence by putative risk factors were compared. A multiple logistic regression model was fit to assess putative risk factors and difference between groups simultaneously. RESULTS Race, age, previous dental visit, parents' education, and household income were significantly associated with ECC prevalence. Parents' place of birth was a significant effect modifier with lower ECC among Boston children of immigrants than among US children of immigrants. CONCLUSIONS Lower ECC prevalence among urban Boston children of immigrant parents compared with US children of immigrant parents may reflect changing immigrant composition in the United States since NHANES III or a different immigrant composition in the Boston area compared with the United States. This finding reinforces the need for further research of immigrants in order to understand cultural practices that may affect oral health. Finally, low ECC prevalence among very young children reinforces the importance of early intervention in reducing ECC.

Abstract
AIM This was to investigate caries experience and patterns in a sample of 5-year-old children attending nursery schools in the Veneto Region (Italy). STUDY DESIGN Cross sectional study. METHODS The study was carried out between September 2005 and May 2006 with 348 randomly selected 5-year-old children. Two calibrated dentists using an artificial light, a plane dental mirror and a dental probe performed clinical dental examination. World Health Organisation (WHO) diagnostic criteria for dental caries: dmft, dmfs and SiC indexes were used to measure the severity of the disease. STATISTICS dmfs scores were analysed either as a continuous continuous (calculating means and standard deviations) or as a categorical variable (providing proportions). Pearson's chi square test for comparison between groups and Wilcoxon signed-rank test for distribution of dmfs scores between pairs of contiguous molars were used. RESULTS The most commonly affected teeth were primary molars, (78% of the overall sample), especially in the mandible. The surfaces of molars most often affected were the occlusal (52%). Proximal surfaces were affected more in first than in second primary molars. Dental caries occurred most often in the maxilla. The frequency of caries in anterior teeth was low (12%). CONCLUSIONS Caries experience in the primary dentition showed a symmetrical distribution localized on primary molars, most often in their occlusal surface. Caries in anterior teeth was uncommon.

Abstract
AIM To provide a review of the existing literature on early childhood caries (ECC) with particular reference on the nomenclature, case definition, epidemiology, etiology and risk assessment. METHODS An electronic search was used to identify and critically review papers that have been published and are pertinent to the above issues, evaluate and compile the reported evidence. RESULTS The term ECC has been adopted to more accurately describe dental caries that affects primary dentitions, replacing previously used terminology that associated the disease with the nursing habit. Suggested ECC case definition uses caries patterns as defining criteria, however, further refinement to include different clinical expressions of a varying severity is necessary. Significant percentages of preschool child populations are affected by ECC today, with the disease concentrating disproportionately in deprived families. Early colonization by mutans streptococci (MS) is associated with increased ECC development, with bacteria being transmitted in both vertical and horizontal ways. Dietary factors related to sugar consumption predispose to early MS colonization and establishment and increase the risk for ECC development, being part of the causal chain. Inappropriate bottle and breast-feeding behaviors also increase the risk, without showing a direct causal relationship. High risk children belong to ethnic minority groups and to low income families with poor parental behaviors and attitudes. CONCLUSIONS Further high-quality studies are needed to explore the role bacteria other than MS may play in caries initiation and progression, elucidate the interaction of the saliva immune defence system with a potentially defective tooth, and investigate the effect distant behavioral factors have on the causal chain that leads to ECC development.

Abstract
Oral health is integral to general health and essential to well-being and quality of life. Socio-behavioural and environmental factors play a significant role in oral disease and oral health. Dental caries is a global disease with few populations exempt from its effects. In developing countries, as development increases so does dental caries and children are at the forefront of the disease disadvantage. There is a growing need to identify high caries risk groups accurately to commence prevention from a young age. The effect of early intervention in childhood on general and dental health with both population and high-risk approaches also needs examining. As an educational tool, the paediatric food-based dietary guidelines may play a significant role in nutrition and oral health interventions. This paper provides information on nutrition, including access to fluoride and use of sugar. Oral health concerns, such as early childhood caries, which are important for the young child, are also discussed.

Abstract
OBJECTIVE Despite limited epidemiologic evidence, concern has been raised that breastfeeding and its duration may increase the risk of early childhood caries. The objective of this study was to assess the potential association of breastfeeding and other factors with the risk for early childhood caries among young children in the United States. METHODS Data about oral health, infant feeding, and other child and family characteristics among children 2 to 5 years of age (N = 1576) were extracted from the 1999-2002 National Health and Nutrition Examination Survey. The association of breastfeeding and its duration, as well as other factors that previous research has found associated with early childhood caries, was examined in bivariate analyses and by multivariable logistic and Poisson regression analyses. RESULTS After adjusting for potential confounders significant in bivariate analyses, breastfeeding and its duration were not associated with the risk for early childhood caries. Independent associations with increased risk for early childhood caries were older child age, poverty, being Mexican American, a dental visit within the last year, and maternal prenatal smoking. Poverty and being Mexican American also were independently associated with severe early childhood caries, whereas characteristics that were independently associated with greater decayed and filled surfaces on primary teeth surfaces were poverty, a dental visit within the last year, 5 years of age, and maternal smoking. CONCLUSIONS These data provide no evidence to suggest that breastfeeding or its duration are independent risk factors for early childhood caries, severe early childhood caries, or decayed and filled surfaces on primary teeth. In contrast, they identify poverty, Mexican American ethnic status, and maternal smoking as independent risk factors for early childhood caries, which highlights the need to target poor and Mexican American children and those whose mothers smoke for early preventive dental visits.

Abstract
The aim of this investigation was to study the effects of prolonged breast- or bottle-feeding on dental caries in Japanese infants. This longitudinal study was conducted by means of a questionnaire and clinical examination of 592 children at 18 months, 2 years and 3 years of age. The children were divided into three groups: 1) children still being breast-fed at 18 months of age (n=42); 2) children still being bottle-fed at 18 months of age (n=45); and 3) children weaned off of breast- or bottle-feeding and with no nonnutritive-sucking habits at 18 months of age (n=205). Results showed that breast-feeding at 18 months of age produced many significant differences to the control children, including a higher prevalence of caries and higher number of dft. However, no significant differences were observed between bottle-fed and control children. In conclusion, our results suggest that prolonged breast-feeding at an early age before primary dentition has fully erupted is a risk factor for dental caries. Therefore, breast-fed children need to be monitored more closely, and aggressive methods of preventive care need to be instituted. It is also important to identify factors related to dental caries among breastfed children as soon as possible, and develop effective preventive programs.

Abstract
BACKGROUND The authors conducted a study to compare the effect of a motivational interviewing counseling treatment with that of traditional health education on parents of young children at high risk of developing dental caries. OVERVIEW The authors enrolled in the study parents of 240 infants aged 6 to 18 months and randomly assigned them to either a motivational interviewing, or MI, group or a traditional health education (control) group. Parents in the control group received a pamphlet and watched a video. Parents in the MI group also received the pamphlet and watched the video; in addition, they received a personalized MI counseling session and six follow-up telephone calls. RESULTS After one year, children in the MI group had .71 new carious lesions (standard deviation, or SD, = 2.8), while those in the control group had 1.91 (SD = 4.8) new carious lesions (t[238] = 2.37, one-tailed, P < .01). CONCLUSIONS MI is a promising approach that should receive further attention. CLINICAL IMPLICATIONS MI may lead parents and others to better accept dental recommendations about preventing caries in their children.

Abstract
OBJECTIVE Clinical patterns of early childhood caries (ECC) encompassing specific teeth or surfaces have been previously proposed on an a priori basis and have been used as case definitions. The underlying assumption is that the patterns result from different host response and environmental conditions. Identifying caries patterns has utility in refining case definitions of ECC. Well-defined caries patterns should enhance the ability of an analysis to identify meaningful associations between suspected risk factors and ECC. The purpose of this project was to identify patterns of caries in the dentition of preschool children using multidimensional scaling without a priori pattern delineation. METHODS Between February 1994 and September 1995, five examiners visually examined 5171 Arizona preschool children aged 5-59 months old. Multidimensional scaling (MDS) was used as a classification/taxonomy technique to identify any underlying structure of the caries data. MDS provided a classification scheme for individual tooth surfaces based on the dissimilarity measures of squared Euclidean distance and of variance using an alscal analysis. Both two- and three-dimensional solutions were pursued; s-stress, stress, R-square and residual patterns were assessed in determining the best dimensional model, with the resulting quadrant positions of the tooth surfaces suggesting potential caries patterns. RESULTS All models demonstrated excellent fit. Two- and three-dimensional solutions suggested four caries patterns: (i) any maxillary incisor surfaces, (ii) first molar occlusal surfaces, (iii) second molar pit and fissure surfaces, and (iv) any smooth surfaces, excluding the maxillary incisor surfaces. CONCLUSIONS This is the first delineation of primary dentition caries patterns produced by a classification analysis without a priori pattern definitions. The identified caries patterns may arise from specific risk factors and/or be a function of the timing of various risk factor exposures. Use of these patterns as case definitions should enhance the ability to identify associations between suspected risk factors and ECC.

Abstract
OBJECTIVE To evaluate the cares status of Sri-Lankan Veddha children in relation to the traditional risk factors. Prevalence of dental caries is still high in certain populations, studies of which may shed additional light on the complex aetiology of caries. METHODS Using the NIDR criteria for caries diagnosis, the Strip Mutans technique (Dentocult SM), and a questionnaire administered by a native speaker, 39 children between the ages of 2-17 years were examined in a cross-sectional study. RESULTS Of the 2-9-year-olds, 33% were caries free in the primary dentition and 72% of 5-17-year-olds were caries free in the permanent dentition (mean dft = 2.7; SE = 0.61 and mean DMFT = 0.9; SE = 0.41). There was no correlation between caries and mutans streptococci levels. Excessive consumption of sugar or honey was significantly correlated with the mean dft levels (P = 0.007). The mother was the primary caregiver for all but two children and the children were breast-fed for an average of 2.8 years (SD = 0.82). The duration of breast-feeding was not correlated with the caries experience. CONCLUSION Lack of professional and home care and unfavourable dietary practices may be related to the high prevalence of caries observed in this population.

Abstract
OBJECTIVES Modeling new biomedical technologies and determining their expected cost is necessary before initiating formal clinical trials. This paper estimates an economic model for the potential cost impact of microbiological screening of toddlers for caries risk compared to the traditional method of managing pediatric caries. METHODS Potential cost savings were calculated based on screening test properties (sensitivity and specificity) derived from a population of 1,180 children aged 1 to 3 years with a caries prevalence of 15 percent. An algorithm was then developed to allocate prevalent and anticipate incident caries, treatment effectiveness assumptions, and existing regional treatment costs. RESULTS The cost analysis model conservatively predicts savings of 7.3 percent from screening and early intervention. Cumulative dental treatment costs for a child at age 4 years are $367.90 if the child has been screened and $396.70 otherwise. The model further predicts that cost savings increase significantly as caries prevalence increases. CONCLUSIONS Microbiologic risk assessment for pediatric caries may be an example of a preventive public health screening technique that results in both clinical benefits and cost savings. If the model is validated by randomized clinical trials, microbiologic screening could be used by pediatric primary care providers to identify toddlers who require early referral to dentists for further risk assessment and early caries management.

Abstract
OBJECTIVES The aim of this investigation was to compare clinical data regarding oral status (DMFT/DMFS indices) and streptococci or lactobacilli counts in stimulated whole saliva in two groups of children, aged 6 and 8 years. METHODS Seventy-nine boys and 93 girls aged 6 (84 subjects) and 8 (88 subjects) years old were selected. DMFT/dmft, DMFS/dmfs and OHI-S indices were recorded. Mutans streptococci (Sm) and lactobacilli (Lb) salivary levels were assessed using commercially available strip tests and were rated from 0 to 3 and from 0 to 4 in the group as a whole. RESULTS Mean dmfs was 9.06 +/- 10.80, made up of ds = 7.28 +/- 9.54, fs = 1.19 +/- 3.64 and ms = 0.59 +/- 3.47. Mean DMFS was 0.73 +/- 1.91, made of DS = 0.54 +/- 1.29, FS = 0.08 +/- 0.56 and MS = 0.11 +/- 0.56. Statistically significant differences were found for both Sm and Lb scores between those with and without caries in the primary teeth (P < 0.05). The different Lb scores were also significant in relation to caries in permanent teeth in older children. CONCLUSION A high proportion of children had some caries experience, and were in need of treatment.

Abstract
The prevalence of dental caries was studied in 3-5-year-old Uruguayan children (n = 76) living in 2 areas with different socioeconomic and cultural conditions. More children from the low socioeconomic area of Las Acacias had caries (68%) than children from the middle- to high-class neighborhood of Pocitos (19%). They also had poorer oral hygiene and a significantly higher caries prevalence (P < 0.05) than those from Pocitos. The occurrence of mutans streptococci and lactobacilli was determined in whole unstimulated saliva and compared with that in debris collected with a loop from the dorsum of the tongue. Mutans streptococci were detected in 42% of the children with significant correlations between the salivary levels of the microorganism and caries experience. Lactobacilli were recovered less frequently (18%). The detection of mutans streptococci in the tongue-loop samples was significantly correlated with that in whole saliva.

Abstract
Early childhood caries (ECC) is primarily a disease of poor, minority population children who generally have limited access to dental services. Public health dental clinics have not made the prevention and control of ECC a priority, and the services provided have not controlled ECC. New training and early screening are recommended. Additionally, repeated accessing of mothers and children through prenatal and postnatal medical visits is recommended. At such visits behavioral and chemotherapeutic strategies need to be utilized. Examples from a demonstration project in the Commonwealth of Northern Marianas are presented.

Abstract
OBJECTIVE This investigation assessed two methods for estimating epidemiologic indicators of oral health status among children: (1) a visual-only screening, performed independently by a dental hygienist and a registered nurse; and (2) a parent- or guardian-completed questionnaire. The indicators included dichotomous variables measuring dental caries and treatment needs, presence of sealants, injuries to the anterior teeth, and dental fluorosis. METHODS Following training and calibration, data were collected over an eight-day period in April 1994 among 632 elementary schoolchildren (aged 5 to 12 years) in Monticello, Georgia. Both screening and questionnaire findings were compared pairwise with results from visual-tactile examinations done by a dentist. Validity, represented by sensitivity, specificity, and predictive values, was assessed for screening results from the dental hygienist, the nurse, and the parent-completed questionnaire. RESULTS Validity was high for screening for caries and treatment needs (> 90% for sensitivity, specificity, and predictive values in a sample having 30% to 40% prevalence). Less valid data--mainly an effect of false negatives--were obtained for fluorosis, injuries, and presence of sealants. No significant difference in validity was observed between the nurse and the dental hygienist. One-third of respondents to the questionnaire did not know if their children needed fillings (a proxy for untreated decay) or had received sealants; only knowledge of restorations was comparable to results from screening. Intraexaminer reliability for the two screeners ranged from 85 to 100 for percent agreement and 0.70 to 0.93 for kappa scores. CONCLUSIONS Screening by dental hygienists or nurses can provide valid data for surveillance of dental caries and treatment needs. Training for visual assessment of fluorosis and injuries must be improved to diminish the proportion of false negatives. A parent-completed questionnaire is less effective than visual screening for evaluating oral health status in children.

Abstract
This paper considers the question of whether, by using the currently available measures for assessing caries risk, one can identify with sufficient accuracy the high caries-risk susceptible individuals who need individual protection to avoid having an unacceptably high number of new cavities. In addition, the outline of a typical caries prediction study is presented with an example, Finally, the accuracy of an actual caries prediction is compared with the accuracy of predicting the onset of acute myocardial infarction in order to point out the fact that the risk of any disease is difficult to assess accurately.

Abstract
OBJECTIVES The purposes of this study were to assess current dental caries experience and levels of mutans streptococci in Apache children in 1993 and to determine how caries levels and patterns were different from 15 years before. METHODS Four-year-old Head Start children (n = 127) were examined for dental caries and sampled for salivary mutans streptococci in 1993. Dental caries information on 113 4-year-old children from the same location was obtained from a chart audit of the 1978-79 Head Start dental examinations. RESULTS Neither the caries prevalence (95%) nor the prevalence of caries patterns differed between the 1978-79 and 1993 cohorts. However, the level of treatment received in 1993 was greater than that in 1978-79. Children with nursing caries (64%) had a greater severity of fissure caries and a greater prevalence of posterior proximal caries compared with caries-positive children without nursing caries. The mean dmfs and dmft on the children categorized in the high mutans streptococci range were greater than those of children categorized in the moderate range. CONCLUSIONS The caries prevalence found in these preschool Native Americans is among the highest reported for this age group and does not differ from that found at this location 15 years before. It appears that children with nursing caries in this population are at greater risk for posterior caries patterns.

Abstract
Recent studies have suggested that the identification of caries as discrete patterns may be valuable in describing and predicting caries experience on an individual basis. The purpose of this study was to assess the association between levels of salivary mutans streptococci and the prevalence, incidence and distribution of caries patterns in the primary dentition. A cohort of pre-school children (n = 146, mean age 3.8 yr) were examined for dental caries and sampled for salivary mutans streptococci (SMS) at baseline and once annually for 2 yr. Children's tooth surfaces were categorized into four patterns: pit/fissure, maxillary anterior, posterior proximal, and buccal/lingual smooth surface. Salivary mutans streptococci were enumerated using a tongue blade technique, and were categorized as low (0 CFU), moderate (1-50 CFU) and high (> 50 CFU). At year 2, children with high baseline SMS had the 1) highest prevalence of caries (87%) and the highest dmfs (9.15); 2) highest prevalence of each pattern, and 3) greatest number of patterns. Among children with the pit/fissure pattern, those with high baseline SMS had the greatest pit/fissure dmfs after 2 yr. Results show that baseline SMS levels were associated with both cross-sectional and longitudinal caries experience, numbers of caries patterns, and the prevalence and severity of those patterns.

Abstract
OBJECTIVES This study assessed the development of caries in preschool children over two years according to baseline caries pattern. METHODS Connecticut Head Start children (n = 142, mean age = 3.8 years) were examined for dental caries at baseline (spring 1991) and once annually for two years. Children were categorized at baseline as caries-free, having pit and fissure (PF) caries, or having maxillary anterior (MA) caries. RESULTS After two years, children who presented at baseline with MA or PF caries had a mean posterior dmfs of greater than seven and four times, respectively, that of children who were caries-free at baseline. When dental caries of the primary dentition was categorized by specific posterior patterns (i.e., posterior proximal [PP] and buccal/lingual [BL]), change in dmfs for the PP and BL patterns in the group that presented with pit/fissure caries at baseline were nearly four and three times greater, respectively, than for those in the caries-free group. The group that presented with maxillary anterior caries at baseline had PP and BL caries increments eight times those of children who began caries-free. CONCLUSION Dental caries presentation in 3- to 4-year-old children can identify those children and tooth surfaces that will be at the greatest risk for future caries development.

Abstract
The purpose of this study was to describe the dietary habits of infants and toddlers living in Sweden with special reference to caries prevalence at 2 and 3 years of age and to immigrant status. The study was designed as a prospective, longitudinal study starting with 671 children aged 1 year. At 3 years, all children were invited to a further examination. A total of 298 individuals, randomly selected from the original group, were also examined at 2 years. The accompanying parent was interviewed about the child's dietary habits. Children with caries at 2 and 3 years of age and immigrant children had, when they were 1 year old, consumed caries-risk products and been given nocturnal meals and sweetened liquid in a feeding bottle more often than caries-free 2- and 3-year-olds and non-immigrant children. Although a great variation in dietary habits was found in infants and toddlers, the use of sugar-containing products is widespread in Sweden even in early childhood.

Results were analyzed with the traditional dmfs/t index and with the Caries Analysis System. The system differentiated between caries patterns and examined the percentage of affected children (Prevalence), the degree to which these children were affected (Severity), and the proportion of total caries each disease pattern represented (Distribution). Over 67% of the children experienced caries, a level comparable to other reports from China and other developing countries, but 50% greater than those seen in United States preschool children. Nearly all children with caries experienced fissure caries. In 3-yr-olds maxillary anterior caries was the next most prevalent pattern with 43% affected, whilst in the 6-yr-olds, posterior proximal caries was the second most prevalent pattern with 68% affected. Since maxillary anterior caries was so prevalent, and because the presence of this pattern has been shown to be a risk factor for future caries, preventing the maxillary anterior pattern may markedly reduce caries in this population.

Abstract
OBJECTIVES The purpose of this study was to assess the dental health of Navajo preschool children, a population about whom little dental information is published. METHODS Caries data were collected and analyzed for 2,003 Navajo children aged 3-5 years in the Head Start program, and for a convenience sample of 115 children younger than three years old from the Women, Infants and Children (WIC) program. RESULTS Each age group had an extremely high mean dmfs; however, as much as 70 percent of this index comprised treated surfaces. Maxillary anterior caries was observed in the WIC children under two years of age and posterior proximal caries was observed as early as two years of age. The prevalence of maxillary anterior caries reached a maximum of 68 percent in the three-year-old Head Start children, and may be associated with the high level of posterior caries in this population. CONCLUSIONS Most children in this population may be considered at risk for developing caries. This Navajo preschool population has perhaps the earliest caries onset, among the highest caries prevalence, and among the highest level of treatment of any reported population.
