Caries risk assessment in chilean adolescents and adults and its association with caries experience
Rodrigo Andrés Giacaman,Paulina Miranda Reyes,Valeria Bravo León
Brazilian Oral Research , 2013, DOI: 10.1590/s1806-83242013000100002
Abstract: Cariogram is a computer program that uses an algorithm to assess caries risk. Although the use of Cariogram has recently increased, little information is available regarding its effectiveness in adults. This study aimed to determine whether caries risk from Cariogram relates to caries experience in adults. One hundred and eighty Cariogram files were completed from patients aged ten to fifty-six years (mean: 23.28 years). Seven factors from the software were included from patient records to complete the Cariogram: caries experience, diet (content and frequency), stimulated salivary flow, hygiene index, related diseases and fluoride usage. The percentages of "chances of avoiding new lesions" (caries risk) were obtained from Cariogram, and the subjects were classified into five risk groups. Results were compared for each variable with ANOVA, and a correlation between caries and Cariogram variables was calculated by Pearson's correlation coefficient. A multivariate regression model was also used. Only three patients were classified as low risk, and none were classified as very low risk. Thus, only the four upper quintiles were considered for the analysis, and the lower quintile was not considered in the study. Neither DMFT nor the number of lesions were significantly different among the Cariogram's risk categories (p > 0.05). Only diet content was significantly correlated with caries experience (p = 0.006). Caries lesions failed to correlate with any Cariogram variable (p > 0.05). Age, not sex or caries risk scores, showed a strong and positive association with DMFT (p < 0.01). Caries risk from Cariogram appears to be unrelated with caries experience or caries lesions in a high-caries adult population.

Abstract: introduction: the diagnosis of caries susceptibility is a challenge which the present diagnostic procedures have to face. the presence of acids in the oral environment leads to a ph-level decrease, with lactic acid being the main responsible for this situation; the possibility of detecting its levels in the mouth could be used as an adequate diagnostic tool for assessing the individual caries risk. materials and methods: in this preliminary study we evaluate a test recently launched on the market by 3m (clinpro? cario l-pop), which allows to measure on an ordinal scale the presence of lactic acid on the lingual surface. we have related the mean number of non-treated decay in 24 children between 6 and 14 years of age to the lingual surface lactic acid levels measured with the new test. results: in those patients with low lactic acid levels (low risk patients), according to the test, we did not observe any tooth with active caries lesions. there is an increase in the mean number of teeth with active caries in patients with are classifies as medium or low-risk patients according to the test. conclusion: this new test could be a useful auxiliary tool for evaluating the individual caries susceptibility risk. nevertheless, it is necessary to perform longitudinal studies in order to know its efficacy in the prediction of caries risk.
PRESENCE OF Streptococcus Mutans IN SALIVA AND ITS RELATIONSHIP WITH DENTAL CARIES: ANTIMICROBIAL SUSCEPTIBILITY OF THE ISOLATES

Universitas Scientiarum , 2004,
Abstract: Dental caries is a localized, transmissible, pathological infectious process that ends up in the destruction of hard dental tissue. Streptococcus mutans is considered to be the main cause of dental caries. Indeed, numerous reports have shown the close relationship between salivary levels of S. mutans and dental caries. The purpose of this study was to determine the relationship between the presence of Streptococcus mutans and dental caries, and to evaluate the antimicrobial susceptibility of the isolates. Unstimulated saliva was collected from 53 3 to 5-year-old children from the Diego Torres school in Turmequé (Boyacá, Colombia). Saliva samples were vortexed and serially diluted in 0.05 M phosphate buffer. Aliquots of 100 ul of the appropriate dilutions were cultured on Mitis Salivarius Bacitracin agar medium for the selective isolation of S. mutans, and incubated anaerobically for two days at 37 o C. The minimal inhibitoryconcentrations of the S. mutans isolates were evaluated against penicillin, amoxicillin, cefazolin, erythromycin, clindamycin, imipenem and vancomycin by an agar dilution method. The dental caries experience in these children was 66% (35/53) and S. mutans was found in the saliva of 33 children (62%); 21 of them had dental caries and 12 did not. In the 20 children from whom S. mutans was not isolated, 14 (70%) were found to have caries. There were no statistically significant differences in S. mutans counts between the group with dental caries and the caries-free group (p=0.21). All isolates were highly sensitive to penicillin, amoxycillin, cefazolin, erythromycin, clindamycin, imipenem and vancomycin; 50 and 90% of the strains from S. mutans were inhibited by concentrations of less than 0.12 and 0.5 ug/ml, respectively, for all antibiotics studied. In conclusion, not all of the children hosting this microorganism had caries, and the S. mutans strains were highly sensitive to the antibiotics tested.

Abstract: Destruction of calcified tissue was caused by acids which are by product of carbohydrate metabolism of acidogenic bacteria consequent to dental caries. The purpose of this study was to assess the existence of acidogens potentially causing the dental caries and comparatively evaluation of efficacy of different toothpastes. The dental plaques of fifty persons belong to three age groups (1 - 20, 21 - 40, 41 - 60 year and above) were examined to identify microorganisms by the culture method. Thirty nine bacteria were isolated by spread plate method on BSMY I minimal media. Thirteen out of thirty nine, acidogens colonized in the dental plaques. Seven potentially acidogens CD17, CD26, CD27, CD28, CD29, CD34 and CD35 were treated with five different toothpastes. Inhibition effect of Triclosan and Fluoride containing tooth pastes were found more efficient. The results of the present study revealed that bacteria that commonly cause dental caries colonized in dental plaques of children and alcoholic person. Therefore, dental plaques must be considered a specific reservoir of colonization and subsequent dental caries. To reduce the dental problem triclosan and fluoride containing product should be recommended.

Iranian Journal of Public Health , 2005,
Abstract: Objectives: The study examined the hypothesis that severe dental caries may affect growth and development in preschool children. Methods: The study examined 218 children with severe caries using standard diagnostic criteria. All children were weighed and measured and a food frequency questionnaire was completed for each. Six months subsequent to tooth extraction, 131 of the children were followed up and underwent repeat measurement of height, weight, dental health and food intake. For each child, body mass index (BMI) was calculated, and all measurements were converted into standard deviation scores and compared to the UK 1990 growth reference. Results: In the six months period after having their decayed teeth extracted the children’s BMIs had increased by 0.654. Two-sided t-tests for paired data showed this difference to be significant (P< 0.01). Conclusion: Treatment of gross dental disease appears to promote "catch-up" growth and normalisation of body mass index.

Indian Journal of Dental Advancements , 2011, DOI: 10.5866/3.3.563
Abstract: Aims and objectives: The present study was carried out to know the prevalence of dental fluorosis and the relation of dental fluorosis at varying degree of fluoride concentration in drinking water among the study subjects. Methodology: The study population was selected by stratified cluster random sampling methodology. A total of 1810 school children were screened for dental fluorosis. Data was entered into computer and analyzed using (SPSS 11.5 version). Chi square test was used for comparison of fluorosis and various levels of fluoride concentration in drinking water. Results: It was observed that number of children affected with dental fluorosis increases with the increase in level of concentration of fluoride in drinking water. The results of the study indicated that dental fluorosis exists irrespective of levels of fluoride concentration in drinking water.
Chemo Mechanical Caries Removal A New Horizon
Pratap Kumar M,Nandakumar K,Sambashivarao P,Sandhya P S
Indian Journal of Dental Advancements , 2011, DOI: 10.5866/3.4.668
Abstract: In this era of minimal intervention dentistry, the changing concept of cavity preparation and the introduction of reliable adhesive materials have lead to the development of alternative methods of caries removal. Chemo mechanical caries removal (CMCR) involves the chemical softening of the carious dentine, followed by its removal with gentle excavation. This process removes only the infected tissues thereby preserving the healthy dental structures, avoiding pulpal irritation and patient discomfort. Chemo mechanical caries removal has gained high acceptance among children, dental phobic's and medically compromised patients. This article presents a comprehensive review on chemo mechanical caries removal using caridex, carisolv, and papacarie.
