Abstract: Introduction: The Significant Caries (SiC) has been defined to determine dental caries for different societies by Word Health Organization. The good of present study was to evaluate Sic in 12-year-old students in city of Isfahan and make a comparison with dental caries risk factors.Methods and Materials: This was a descriptive cross sectional study. Three hundred and forty students, 12-year-old from Isfahan city were examined according to SiC Index by means of mirror and explorer. Risk factors and decay were evaluated recorded in separate check list. Findings were analyzed by Chi-square and SPSS soft ware.Results: The mean DMFT for all students were 2.4 and SiC Index was 4.6, which were directly related to factors such as regular brushing, parents’ educational level, mothers’ occupation families income, consump-tion of sweets, number of children in the family.Conclusion: SiC Index in 12-year-old students in Esfahan city was far from ideal SiC Index determined by World Health Organization which is 3. Therefore more attention to this group of student is recommended.

Abstract: Background and aims. Dental caries still remains a major problem in the field of oral and dental health and its prevention is more important than its treatment. Fluoride plays a significant role in prevention of caries, and improving oral and dental health. One of the common ways of fluoride use is the use of a fluoride-containing mouthwash, the most important of which in use is 0.2% sodium fluoride mouthwash. School-based fluoride mouthwash programs have been used for delivering oral and dental health to children in recent years. The aim of the present study was to assess the efficiency of 0.2% sodium fluoride mouthwash in prevention of dental caries according to DMFT index. Material and methods. The study included a case and a control group. For each group, 100 students were selected randomly from elementary schools of Tabriz, Iran. Case group had been participating in school-based fluoride mouthwash program for three years, while control group did not benefit from the program. The two groups were assessed by means of intra-oral examination. Data was recorded using DMFT index. Results. Following the use of 0.2% sodium fluoride mouthwash, mean DMFT index in case group decreased as much as 51.5% compared to that of control group. The mean values of decrease for the decayed, missing and filled indices were 45%, 44% and 59%, respectively. The decrease in DMFT value of the case group compared to that of control group was statistically significant (p< 0.001). A statistically significant decrease was seen in the decayed and filled indices of case group (p=0.042 and p=0.016, respectively), however the missing index did not show any statistically significant difference between the two groups (p=0.361). Conclusion. According to this study results, the weekly use of 0.2% sodium fluoride mouthwash program has been successful in elementary schools of Tabriz. Such program can play an important role in the improvement of oral and dental health among children of school age.

Abstract: In all cohorts, dental caries (DMFT and SiC Index according to WHO indications), was measured. For each variable measured (DMFT and sub-indices, SiC Index), differences in proportions among the five cohorts during the fifteen years were tested using χ2-square test.The mean DMFT index decreased from 4.3 ± 3.1 in 1989 to 0.8 ± 1.5 in 2004. The prevalence of untreated caries (DT) had a notable decrease between 1992 and 1995, increased slightly between 1995 and 1998 and had the greatest decrease in 2004. The number of filled teeth remains low. The percentage of caries-free children increased from 10% to 64%, whereas the percentage of untreated caries changed from 44% in 1989 to 62% in 2004. SiC Index decreased from 7.8 in 1989 to 3.9 in 2004.On the basis of the results of DMFT and SiC Index, caries experience has been reduced. The vigilance and the promotion of a higher standard of personal oral hygiene and dental check-ups are necessary to obtain an improvement of oral status in the future adult population and to reach the new WHO global goals.Dental caries remains the single most common disease of childhood that is not self-limiting or tractable with antibiotics. During a relatively short period of time (about twenty-five years), dental caries has undergone to a striking reduction in most industrialized countries [1,2]. Many factors played a role in this decrease. Most authors agree that the widespread use of fluoride in the toothpaste is the main reason for this decrease [3,4]. Preventive programs and changes in the restorative dental treatment approach are reported as important factors, too [5-7]. However, the real contribution of health services in the improvement of oral health, remains unclear. A possible contribution of the dental services to the caries decrease is the change in the diagnostic and treatment criteria [8]. The improvement in oral hygiene and the natural cyclical variation may also explain the decrease. The mass media and the advertisement bring ne

Abstract: objective: to determine the prevalence of caries, deft and dmft indices (sum of decay, messing, and filling tooth in primary and permanent dentition), and the significant caries index (sic) in scholars from leon, nicaragua. patients and method: dental data from a representative sample of 1,400 children were collected and analyzed in a cross-sectional study (year 2002). all subjects were clinically evaluated by one of two calibrated and standardized examiners. results: 28.6% children were caries free in both dentitions. caries prevalence in primary teeth in 6-years-old children was 72.6% and 45.0% in permanent teeth in 12-years-old children. mean deft and dmft were 2.98 ± 2.93 (n = 1,125) and 0.65 ± 1.43 (n = 1,379), respectively. the sic at 12 years of age was 4.12. children with caries experience in primary teeth were more likely to have caries in permanent teeth (odds ratio = 2.48; 95% confidence interval, 1.66-3.79) than children without caries in primary teeth. conclusion: low caries prevalence and experience were observed in the permanent dentition, with a substantial proportion of filled teeth. such favorable finding was not observed in the primary dentition. levels of caries failed to meet the oral health goal of fdi/who for the year 2000 in 6-years-old. however, the levels found in 12-year-olds had already met the goal for 2000. the present findings confirmed prior reports that the caries experience in primary teeth is associated with the experience of caries in permanent teeth.

Abstract: objective: to examine the relationship between the presence of enamel defects, dental caries in primary teeth, and exposure to various fluoride technologies and the presence of dental caries in permanent teeth in children with mixed dentition. materials and methods: a cross-sectional study was conducted in 713 children aged 6-9 years old in 4 elementary schools in campeche, mexico through the use of a questionnaire for the mothers and an oral examination in the children. the dependent variable was the prevalence of caries in permanent dentition. results: the mean number of decay, missing or filling teeth in primary dentition (dmft) and in permanent dentition (dmft) was 2.48 (2.82) (deft > 0 = 58.9%) and 0.40 (0.98) (dmft > 0 = 18.2%), respectively. the significant caries index (sic), which is calculated in deciduous dentition, was 5.85 for 6 year-olds. multivariate logistic regression adjusted for variables related to fluoride exposure revealed that older age (or = 2.99), a deft of > 0 (or = 5.46), and lower maternal educational level (or = 1.57) were significantly associated with a higher number of dental caries in permanent teeth. an interaction between sex and enamel defects was also found. conclusions: the number of dental caries in both primary and permanent dentitions was relatively smaller than that found in prior studies performed in mexican populations. the results confirm that the presence of caries in primary dentition is strongly associated with caries in permanent dentition. no significant relationship was found between fluoride exposure and dental caries in permanent dentition.

Abstract: Over 4000 adolescents between ages 12 and 19 (Case Group: N = 2124; Control Group: N = 2045) received oral health screenings conducted in public/private middle and high schools in Nevada in 2008/2009 academic year. Caries prevalence was computed (Untreated decay scores [D-Score] and DMFT scores) for the 30% of Nevada Youth who presented with the highest DMFT score (case group) and compared to the control group (caries-free) and to national averages. Bivariate and multivariate logistic regression was used to analyze the relationship between selected variables and caries prevalence.A majority of the sample was non-Hispanic (62%), non-smokers (80%), and had dental insurance (70%). With the exception of gender, significant differences in mean D-scores were found in seven of the eight variables. All variables produced significant differences between the case and control groups in mean DMFT Scores. With the exception of smoking status, there were significant differences in seven of the eight variables in the bivariate logistic regression. All of the independent variables remained in the multivariate logistic regression model contributing significantly to over 40% of the variation in the increased DMFT status. The strongest predictors for the high DMFT status were racial background, age, fluoridated community, and applied sealants respectively. Gender, second hand smoke, insurance status, and tobacco use were significant, but to a lesser extent.Findings from this study will aid in creating educational programs and other primary and secondary interventions to help promote oral health for Nevada youth, especially focusing on the subgroup that presents with the highest mean DMFT scores.By the year 2000, the World Health Organization (WHO) announced the global average goal for dental caries was to be no more than 3 DMFT (decayed, missing, filled teeth) at 12 years of age [1]. Although there has been a significant decline in dental caries prevalence since the early 1970s, oral
