Guidance intended to reduce fluoride toothpaste ingestion in early childhood was introduced in Ireland in 2002. In 2007, water fluoride concentration was adjusted from 0.8–1.0 to 0.6–0.8 ppm. The objective of this study was to determine the difference in caries and fluorosis levels following introduction of these 2 policy measures. A before-and-after study compared caries and fluorosis in random samples of 8-y-olds in Dublin ( n = 707) and Cork-Kerry ( n = 1148) in 2017 with 8-y-olds in Dublin ( n = 679) and Cork-Kerry ( n = 565) in 2002. Dentinal caries experience (primary teeth, d3vcmft(cde)) and fluorosis (permanent teeth, Dean’s index of very mild or higher) were clinically measured. Lifetime exposure to community water fluoridation (CWF) was classified as “full CWF”/“no CWF.” Effect of examination year on caries prevalence and severity and fluorosis prevalence was assessed using multivariate regression adjusting for other explanatory variables. There was little change in commencement of fluoride toothpaste use at ≤24 mo following introduction of toothbrushing guidance. Among children with full CWF, there was no statistically significant difference in caries prevalence or severity between 2017 and 2002. In 2017, caries prevalence was 55% in Dublin (full CWF) and 56% in Cork-Kerry (full CWF), and mean d3vcmft(cde) among children with caries was 3.4 and 3.7, respectively. Caries severity was less in 2017 (mean 4.2) than 2002 (mean 4.9) among children with no CWF ( P = 0.039). The difference in caries severity between children with full CWF and no CWF was less in 2017 than in 2002 (interaction P = 0.013), suggesting a reduced benefit for CWF in 2017. In 2017, fluorosis prevalence was 18% in Dublin (full CWF) and 12% in Cork-Kerry (full CWF). Fluorosis was predominantly “very mild” with no statistically significant difference between 2017 and 2002. CWF at 0.6 to 0.8 ppm is an effective caries-preventive measure. Results suggested low uptake of toothbrushing guidance, a reduced caries-preventive effect for CWF in primary teeth, and no reduction in fluorosis following introduction of the policy measures.

The aim of this study was to evaluate the urinary fluoride excretion of 2- to 7-year-old children exposed to different water fluoride concentrations in the city of Catolé do Rocha, PB, Brazil. Forty-two children were allocated to 3 groups according to the concentration of fluoride in the water: G1 (n=10; 0.5-1.0 ppm F), G2 (n=17; 1.1-1.5 ppm F) and G3 (n= 15; >1.51 ppm F). The study was carried out in two 1-week phases with 1-month interval between the moments of data collection: in the first phase, the children used a fluoride toothpaste (FT) (1,510 ppm F) for 1 week, whereas in the second phase a non-fluoride toothpaste (NFT) was used. The urine was collected in a 24-h period in each week-phase according to Marthaler's protocol. The urinary fluoride excretion data expressed as mean (SD) in µg/24 h were: G1-FT= 452.9 (290.2); G1-NFT= 435.1 (187.0); G2-FT= 451.4 (224.0); G2-NFT= 430.3 (352.5); G3-FT=592.3 (390.5); and G3-NFT=623.6 (408.7). There was no statistically significant difference between the water fluoride groups, and regardless of the week phase (ANOVA, p>0.05). The use of fluoride toothpaste (1,510 ppmF) did not promote an increase in urinary fluoride excretion. There was a trend, though not significant, as to the increase of urine fluoride concentration in relation to fluoride concentrations in the water. The excretion values suggest that some children are under risk to develop dental fluorosis and information about the appropriate use of fluoride is necessary in this area.

Objectives: Biopure MTAD™, a new root canal irrigant has shown promising results against the most common resistant microorganism, E. faecalis, in permanent teeth. However, there is lack of studies comparing its antimicrobial effectiveness with NaOCl in primary teeth. The purpose of this study was to compare the in vivo antimicrobial efficacy of NaOCl 2.5% and Biopure MTAD™ against E. faecalis in primary teeth. Study design: Forty non vital single rooted primary maxillary anterior teeth of children aged 4-8 years, were irrigated either with NaOCl 2.5% (n=15), Biopure MTAD™ (n=15) and 0.9% Saline (n=10, control group). Paper point samples were collected at baseline (S1) and after chemomechanical preparation (S2) during the pulpectomy procedure. The presence of E. faecalis in S1 & S2 was evaluated using Real time Polymerase Chain Reaction. Results: Statistical significant difference was found in the antimicrobial efficacy of NaOCl 2.5 % and BioPure MTAD™ when compared to saline (p>0.05). However, no statistical significant difference was found between the efficacies of both the irrigants. Conclusions: NaOCl 2.5% and BioPure MTAD™, both irrigants are equally efficient against E. faecalis in necrotic primary anterior teeth. MTAD is a promising irrigant, however clinical studies are required to establish it as ideal root canal irrigant in clinical practice.

Background: The autism spectrum disorder (ASD) has been introduced as one of the complicated developmental disabilities impairing communication and behavioral, intellectual as well as social functioning describes diverse symptoms, such as difficulties in communication skills and social interactions. The present research has been performed to assess seriousness of the dental caries in conjunction with the oral cleanliness amongst children suffering from autism in comparison with a control group according to age groups and gender. Materials and Methods: This research involved 30 children aged 3-14 years (male, female) who suffered from autism and attended autism centers in Welfare Children Teaching Hospital in Baghdad province, Iraq, were selected for the study compared to 30 healthy children with the same age group. Plaque (PlI), Decayed, missing, and filled surfaces (dmfs, DMFS), calculus (CI) as well as Gingival (GI) indices have been applied for measuring the status of oral health for these two groups. The data of our research has been analyzed by SPSS 26. Results: The entire autism group was caries active. For primary dentition, a lower dmfs values were recorded for study in comparison with the controls, differences have been not significant in dmfs, while for permanent dentition, a higher DMFS values were recorded for study in comparison with the control group with statistically significant concerning DMFS (P < 0.05). Moreover, caries experience (DS and DMFS) among both genders were higher in the study group in comparison with the controls with a significant difference in female only. Total mean value of PlI in the study group has been greater than the controls with no statistically significant difference. In addition, total mean value of GI in the study group has been lower than the controls with no statistically significant difference. Furthermore, correlation coefficient between the caries experience of primary and permanent teeth with PlI and GI among study and control group showed no significant correlations seen in the study and control groups, all of them were positively correlated except (ds) with (GI) in control group which was negatively correlated with no significant correlation. Conclusion: children with ASD had higher dental caries severity regarding permanent teeth compared to normal subjects, plaque higher in autistic group than control group. Dental care planners must design preventing strategies for avoiding caries; procedures for oral care as well as educational programs for oral care and promotion for addressing diverse challenges facing the oral care in ASD.

ABSTRACTObjectives: The aim of this study was to investigate the presence of Enterococcus faecalis in endodontic infections in both deciduous and permanent teeth by culture and polymerase chain reaction (PCR) methods.Methods: A total of 145 children aged 5-13 years old were involved in this study. The presence of E. faecalis in necrotic deciduous and permanent teeth root canals was studied using culture and polymerase chain reaction methods.Results: Among 145 molar teeth, 57% (n=83) presented necrotic asymptomatic pulp tissues and were included in this study. Culture and PCR methods detected the test species in 18 and 22 of 83 teeth involved, respectively. E. faecalis was cultured from 8 (18%) of 45 necrotic deciduous teeth and from 10 (26%) of 38 necrotic permanent teeth. PCR detection identified the target species in 10 (22%) and 12 (32%) of necrotic deciduous and permanent teeth respectively. Statistically significant difference in the presence of E. faecalis in deciduous and permanent teeth was found by culture and PCR methods (P=0.03 and 0.02, respectively). The difference in the presence of E. faecalis between two different methods was not statistically significant (P>.05).Conclusions: The results of the present study confirm that both culture and PCR methods are sensitive to detect E. faecalis in root canals.

The aim of the study was to evaluate the factors associated with the prevalence and severity of dental caries as well oral hygiene habits among 4- to 6-year-old children in Kaunas (Lithuania) in 2000 and 2010. Material and Methods. A repeated cross-sectional study was carried out to reveal the changes in dental caries prevalence in 2000 and 2010. The study population comprised 4- to 6-year-old children living in Kaunas city and attending kindergartens. The study consisted of two parts: questionnaires on oral health behavior and clinical examination of children’s teeth by the World Health Organization methodology. Results. A total of 941 4–6-year-old children were examined in 2000 and 2010. The prevalence of dental caries increased from 85.4% in 2000 to 88.4% in 2010; however, the difference was not significant (P=0.28). A significant increase in the dmf-t index, describing the severity of dental caries, was observed (from 7.42 in 2000 to 12.03 in 2010, P<0.001). The percentage of 4- to 5-yearold girls and 5-year-old boys brushing their teeth regularly decreased in 2010. During the period of the study, a significant change in the accumulation of plaque on children’s tooth surfaces was documented (P=0.001). Conclusions. Comparing 2000 and 2010, no significant difference in the prevalence of dental caries among 4- to 6-year-old children in Kaunas was observed; however, the severity of dental caries differed significantly. A significant decrease in regular toothbrushing skills was documented for 4- and 5-year-old girls and 5-year-old boys. The Silness-Loe oral hygiene index was assessed as satisfactory.

This study analyzed comparatively, by confocal laser scanning microscopy (CLSM), the depth of caries-like lesions produced by biological and chemical artificial models in permanent and primary dentin. Six primary molars and six premolars were used. The occlusal enamel was removed and a nail polish layer was applied on the specimens, except for a 4 x 2 mm area on dentin surface. Half of specimens were immersed in acid gel for 14 days (chemical model) and the other half was immersed in BHI broth with S. mutans for 14 days (biological model). After development of artificial caries, the crowns were longitudinally sectioned on the center of the carious lesion. Three measurements of carious dentin depth were made in each specimen by CLSM. Measurements depths were compared between the caries models and between tooth types by one-way ANOVA and Tukey test (a=5%). For permanent teeth, the biological model showed significantly higher (p<0.05) caries depth values than the chemical model. For primary teeth, no statistically significant difference (p>0.05) was found between the caries models. The artificial caries model influenced caries depth only in permanent teeth. There was no difference in carious dentin depth between permanent and primary teeth, regardless of the artificial caries model.

Purpose Many novel materials have been developed such as composite resin, ceramic, zircon or metal-supported ceramic for use in aesthetic restoration of primary teeth and permanent teeth with extensive crown damage. The aim of the present study was to compare microtensile bond strengths on materials using the microtensile bond strength test. Materials and methods The microtensile bond strength on the primary tooth dentin was measured on extracted primary teeth using an indirect method and fracture patterns were evaluated. Results The analysis of bond strengths using the Mann-Whitney U-test did not show significant difference between the rank averages of the compomer and composite resin (p = 0.741). The dentin sections, from which test samples were obtained, contributed to the bond strength; dentin samples obtained just above the pulp had lower bond strength, and the difference was statistically significant (p = 0.005). The adhesive type fracture was the most prevalent fracture type for both materials. Conclusions When the chemical, physiological, and micromorphological differences between primary and permanent teeth are taken into consideration, the success of the materials used for restorations can be different between primary and permanent teeth. Therefore, materials used in the dentistry must be evaluated separately for primary teeth.

Background: It is necessary to understand the prevalence and pattern of distribution of dental caries for better planning and execution of preventive activities in the right dimension. This study provided the base line data about prevalence of dental caries in pre-school children of Bharakahu, Islamabad, and its association with brushing, sugar consumption and previous dental visits. Material and Methods: A total of 384 preschool children aged 3-5-year-old were screened from periurban area of Bharakahu, Islamabad, using type IV screening method. Data about decayed, missing and filled teeth was recorded using decayed-missing-filled teeth (DMFT) index. Socio-demographics, brushing, sugar consumption and previous dental visits were also recorded and analyzed and their association with dental caries was assessed using Chi square and Odds ratio. Results: The overall caries prevalence among the sample was 49%. The mean DMFT score with 1 SD was 2.07±3.215. There was no significant difference in caries prevalence in relation to gender of the children. The most significant association was for brushing and low DMFT. Children who brushed their teeth were 4 times more likely to have a low DMFT score of <1 than those who did not brush at all (P<0.001). Likewise, those who had visited a dentist in the past were twice more likely to have a low DMFT (P=0.003). The association of low sugar consumption and a low DMFT score was statistically insignificant (OR 1.4; P=0.878). Hence, brushing turned out to be the most significant factor in determining the caries experience for a child. Conclusions: This study provided us with the baseline data regarding the prevalence of caries in primary school going children of Bharakahu. The prevalence of unmet dental treatment needs was reflected through a high number of ‘decayed teeth’ as compared to missing and filled ones highlighting the need for restorative care in these children.

Introduction: Fluoride toothpastes are a major reason for the decline in dental caries globally. For fluoride toothpaste to be effective, an adequate amount of Total Soluble Fluoride (TSF) must be available in the toothpastes. Aim: To determine and compare the Total Fluoride (TF), TSF and pH among various toothpaste brands. Materials and Methods: An in-vitro study was conducted during October 2019 on 20 toothpaste samples, which belonged to four groups namely, herbal toothpastes group, nonherbal toothpastes group, medicated toothpastes group and kids toothpastes group. Analysis of the samples was done at the Department of Environmental Engineering Laboratory, National Institute of Technology, Surathkal, Karnataka, India. The TF and the TSF concentration was determined using fluoride ion electrode. The pH was determined using pH meter. Statistical analysis was performed using Statistical Package for Social Sciences (SPSS version 19.0). Analysis of variance (ANOVA) was used by Tukey’s post-hoc test to determine the difference between groups. The level of significance was kept at 0.05. Results: The results showed that there was a significant difference between the toothpaste types for mean TF concentration (p=0.004). The post-hoc test showed that there was a significant difference between herbal and nonherbal toothpastes (p=0.041) where the mean TF concentration for nonherbal toothpastes was 1095.20 ppm when compared to herbal toothpastes was 704.40 ppm. The results showed that there was a siginificant difference between the toothpaste types for Mean TSF concentration (p<0.003). There was a significant difference between medicated and kids toothpastes (p=0.024) where the mean total soluble fluoride concentration for medicated toothpastes was 938.60 ppm when compared to the kids toothpastes was 521.20 ppm. Conclusion: The present study showed that pH of all the toothpastes were either neutral or alkaline and the TSF concentration was less when compared to TF concentrations.
