Abstract
Aim The present in vivo study aims to evaluate and compare the clinical efficacy and survival rate of resin-based composite sealant (Clinpro Sealant, 3M ESPE, Irvine, California, United States of America) with high viscosity glass ionomer (GI) (Equia Forte, GC India, Patancheru, Telangana, India) using atraumatic restorative treatment (ART) sealant protocol in primary molars. Materials and methods The design of the study was a clinical, prospective split-mouth study. A total of 100 contralateral primary molars were selected and divided into two groups. In group I, children received Equia Forte, and in group II, children received Clinpro Sealant. The follow-up examinations were performed in the 1st and 6th months. Simonsen's criteria were used to check for retention. International Caries Assessment and Detection System II (ICDAS II) criteria were used to check for dental caries. The data obtained were subjected to statistical analysis. Results At 6 months, there was no statistically significant difference between the groups with regard to retention and caries preventive effect. Conclusions High-viscosity GI sealants can be applied using the ART protocol and provide an alternative to resin-based sealants. Clinical significance There is a limited number of studies on the performance of ART sealants in primary molars. Thus, the clinical efficacy and survival rate of resin-based composite sealant (Clinpro Sealant, 3M ESPE, Irvine, California, United States of America) with high viscosity GI (Equia Forte, GC India, Patancheru, Telangana, India) using ART sealant protocol in primary molars were evaluated. The research concluded that high-viscosity GI sealants using ART protocol are effective sealants in primary molars. How to cite this article Kaverikana K, Vojjala B, Subramaniam P.

Abstract
OBJECTIVE The aim of this in vivo study was to evaluate the clinical one-year follow-up of a silica- and flouroapatite-reinforced glass carbomer filling material as compared to a resin composite restorative material. METHODS AND MATERIALS In this study, a total of 100 restorations were performed. Caries were removed conventionally with diamond burs. Half of the restorations were restored with nanocomposite resin (TEP) (Tokuyama Estelite, Tokuyama Dental, Japan) and the other half were restored with glass carbomer (GC) material (GCP Dental, The Netherlands). Each restorative material was applied according to the manufacturer's instructions. Restorations were evaluated with modified USPHS criteria at the end of the first week, 6 months, and 12 months. Data were analyzed using Fisher's Exact Chi-Square test, Fisher Freeman Halton Test, and Continuity (Yates) Correction. The Wilcoxon sign test was used for intra-group comparisons of the parameters. RESULTS When the filling materials were compared with one another, a statistically significant difference was observed in the 12th month on the marginal discoloration. A statistically significant difference was observed between the two materials in the 6th month on the marginal adaptation (p<0.05). CONCLUSIONS In view of these results, there is a need to improve the physical properties of the GC filling material in further in vivo studies.

[PMID: 35206153 PMCID: PMC8871583 DOI: 10.3390/ijerph19041966] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 12/16/2021] [Revised: 02/07/2022] [Accepted: 02/08/2022] [Indexed: 02/01/2023]
Abstract
Dental sealants are an excellent means to prevent pits and fissure decay. Currently, there are multiple commercially available sealant materials. The purpose of this study was to assess the retention of glass carbomer fissure sealant and the incidence of secondary caries over a period of 24 months in comparison with a resin-based sealant. Materials and Methods: We included 32 children in the study, with ages between six and eight years and an average age of 6.8 years old. For each child, we sealed four permanent molars (totaling 128 teeth). The study group was divided into sub-groups. Sub-group A was represented by 64 first permanent molars which underwent dental sealing procedures with composite resin-based fissure sealant, Helioseal F™, and sub-group B was represented by 64 first permanent molars which underwent dental sealing procedures with glass carbomer cement, GCP Glass Seal™. The sealants were assessed clinically at 6, 12, 18, and 24 months. Results: The 6-month follow-up evaluation showed no statistically significant differences between the two materials neither regarding sealant retention nor new carious lesions formation (p > 0.05). At the 12-month recall, 57 molars had good retention (89.06%) from sub-group A and 44 molars (68.75%) from sub-group B; there was a statistically significant difference (p = 0.0187) between the two treatment choices only regarding material retention. At the last recall after 2 years, sub-group A had a higher number of molars with perfect sealing (47–73.43%) and 8 molars (12.5%) with new caries lesions and sub-group B had 23 (35.93%) molars with perfect sealing and 15 molars (23.44%) with new caries lesions; there was a statistically significant difference (p < 0.0001) between the two treatment choices only regarding material retention. Conclusions: The glass carbomer retention is very inferior to the resin-based material. The glass carbomer sealant was effective in preventing new caries development, comparable with the conventional resin-based sealant.

Abstract
OBJECTIVES This meta-analysis review aims to answer two questions: 1) What is the effectiveness of hydrophilic resin-based sealant (RBS) in preventing/arresting pits and fissures caries in permanent teeth, and 2) What is the retention rate of a hydrophilic RBS as compared to alternative treatments. DATA Randomized control trials investigating the efficacy of hydrophilic RBS compared to any other (placebo) treatment for permanent teeth. Outcomes were retention rate and caries prevention/arresting. SOURCES A systematic search for eligible studies was conducted on six electronic databases (Scopus, Ovid MEDLINE, Ovid Embase, Cochrane; Web of Science, PubMed) from inception to March 2021. The Cochrane guidelines were used to classify the risk of bias. STUDY SELECTION/RESULTS A systematic literature search resulted in 290 studies. Thirteen articles met our inclusion criteria and were included in the systematic review. Six articles were identified as good or fair quality and were included in the quantitative analysis. Meta-analysis results indicated that there is no significant difference in retention (RR 1.01, 95% CI:0.96-1.07, P-value 0.66), (RR 1.03, 95% CI: 0.89-1.19, P-value 0.0009) at six and twelve months, respectively. Likewise, for caries prevention there is no significant difference (RR 0.97, 95% CI: 0.91-1.03, P-value 0.19), (RR 0.30, 95% CI: 0.91-1.03, P-value 0.30) at six and twelve months. CONCLUSIONS This meta-analysis showed no statistically significant difference between the hydrophilic RBS and alternative treatment options (such as conventional resin or glass ionomer) regarding retention or caries prevention at six- and twelve-month follow-up. Future studies are required to investigate longer-term outcomes.

Abstract
Tooth decay in children and adolescents remains a public health problem, despite prophylaxis and preventive measures being largely available. The aim of our study was to evaluate the clinical behavior of four dental sealants, related to first permanent molar topography and patient age (when sealant was applied for the first time). We assessed, by means of visual inspection and palpation with a dental probe, a group of 200 children, enrolled corresponding to school age-grade (mean age of 7 years at baseline) and randomly divided according to the material used as dental sealant (Admira seal©, Embrace Wet Bond©, Fotoseal©, GC Fuji Triaje©) in 4 groups (n = 50). Sealant clinical evaluation was made at 6-, 12-, 18-month intervals for dental material retention assessment. At 6 months, the sealant detached the most from 3.6 molars, and the material used was Fotoseal© (27.6%). At 12 months, Fotoseal© (48.3%) and GC Fuji Triaje© (41.4%) from 3.6 molars express detachment. At 18 months, 4.6. molars sealed with Admira Seal© (25.7%) and Embrace Wet Bond© (28.6%) lost the sealant. We noticed less detachment in maxillary molars and if sealant was applied around 7 years of age. In conclusion, sealant application on first permanent molars must be encouraged and practitioners can choose between various materials available.

Abstract
Aim The aim of this study is to determine the retention rate and pattern of different pit and fissure sealants placed on the occlusal surface of newly erupted first permanent molars after 3, 6, 9, and 12 months. Materials and methods Seventy children were enrolled in this study. They divided into seven groups (m = 10) according to the type of the sealant. The four permanent first molars of each child were sealed. The sealant was applied according to the instructions from the manufacturer. A clinical evaluation was carried out at 3, 6, 9, and 12 months. The clinical observations were divided into three categories: total retention (TR), partial retention (PR), and total loss (TL). Results The resin-based sealant performed better than the glass ionomer-based sealant except for the Ketac Molar Easymix. At 3 months, there was no significant difference among all the tested groups (p > 0.05), while at 6, 9, and 12 months, there was a highly significant difference (p < 0.001). The glass carbomer sealant showed the least retention rate at all intervals. Conclusion With an exception of the Ketac Molar Easymix, resin-based sealers performed better than glass ionomer-based sealers. Clinical significance A proper application of pit and fissure sealant will decrease the chance for caries development in newly erupted teeth. How to cite this article Hassan AM, Mohammed SG.

Abstract
This article presents a discussion paper for both consideration and implementation of Minimal Intervention Dentistry (MID) principles by the general dental practitioner. It argues that if these concepts can be adopted in early childhood by both the community and the profession, "Teeth for Life" can become a reality for all. Oral Health promoting behaviours can be nurtured and supported from infancy and developed into everyday living practice for a lifetime thereby maintaining an optimal quality of life. MID techniques have become more refined and supported by scientific research in the recent times and should be considered an essential clinical guideline for the future disease management.

Abstract
INTRODUCTION/OBJECTIVES Pit and fissure sealants are an essential part of preventive dentistry and should be adopted as a crucial part of the minimally invasive dentistry due to their profound benefit to our patients. METHODS The study design is a single-blind, split-mouth, randomized controlled clinical trial. Forty patients between age 6-9 were selected. First permanent molars' occlusal surfaces with scores of 1, or 2 according to the International Caries Detection and Assessment System II (ICDAS II) and with scores between 14-30 by using DIAGNOdent device (Kavo®, Biberach, Germany) were selected and readings recorded. One side of the mouth was randomly chosen to have either the moisture tolerant resin sealant or the glass ionomer sealant placed, and then the second material was placed on the other side. The retention of these materials was analyzed at 3 and 6 months. The sealants were then removed and DIAGNOdent readings were subsequently taken. RESULTS After three months, full retention was found in 38/40 (95%) teeth in Group A (Embrace™ WetBond™) and 35/40 (87.5%) teeth in Group B (Fuji TRIAGE®). Additionally, no sealant suffered a total loss in group A, whereas, three sealants were totally lost (7.5%) in group B. The difference in sealant retention in two groups in this period was not found to be statistically significant (P > 0.05). At six months, full retention was found in Group A 34/40 (85%) and 25/40 (62.5%) in Group B. Also, the partial loss in Group A was 2/40 (5%) whereas in Group B 7/40 (17.5%). Also, the total loss was 4/40 (10%) and 8/40 (20%) in Group A and B, respectively. The difference in sealant retention in two groups after six months follow-up was found statistically significant (P < 0.05). The initial mean values of DIAGNOdent readings were 22.42 and 22.8 in Group A and Group B, respectively. After six months, DIAGNOdent mean values revealed a drop in both groups, and this difference was statistically significant. Nevertheless, when Group A was compared to Group B in terms of remineralization effect, the differences were found not to be statistically significant (p > 0.05). CONCLUSIONS Within the limitation of this study, we affirmed that occlusal caries lesions, which is restrictive to enamel and in need of surgical intervention, can be arrested clinically by sealing the lesion with both a hydrophilic resin sealant and glass ionomer sealant materials. Embrace™ WetBond™ showed superiority over the glass ionomer sealant tested in retention after six months follow up.

Abstract
Objectives To study the fluoride uptake and release properties of glass carbomer dental cements and compare them with those of conventional and resin-modified glass ionomers. Materials and Methods Three materials were used, as follows: glass carbomer (Glass Fill), conventional glass ionomer (Chemfil Rock) and resin-modified glass ionomer (Fuji II LC). For all materials, specimens (sets of six) were matured at room temperature for time intervals of 10 minutes, 1 hour and 6 weeks, then exposed to either deionized water or sodium fluoride solution (1000 ppm in fluoride) for 24 hours. Following this, all specimens were placed in deionized water for additional 24 hours and fluoride release was measured. Results Storage in water led to increase in mass in all cases due to water uptake, with uptake varying with maturing time and material type. Storage in aqueous NaF led to variable results. Glass carbomer showed mass losses at all maturing times, whereas the conventional glass ionomer gained mass for some maturing times, and the resin-modified glass ionomer gained mass for all maturing times. All materials released fluoride into deionized water, with glass carbomer showing the highest release. For both types of glass ionomer, uptake of fluoride led to enhanced fluoride release into deionized water. In contrast, uptake by glass carbomer did not lead to increased fluoride release, although it was substantially higher than the uptake by both types of glass ionomer. Conclusions Glass carbomer resembles glass ionomer cements in its fluoride uptake behavior but differs when considering that its fluoride uptake does not lead to increased fluoride release.

Abstract
OBJECTIVE The aim of the present study is to update the results of two previous meta-analyses, published in 2006 and 2012, on the survival percentages of atraumatic restorative treatment (ART) restorations and ART sealants. The current meta-analysis includes Chinese publications not investigated before. MATERIALS AND METHODS Until February 2017, six databases were interrogated (two English, one Portuguese, one Spanish and two Chinese). Using six exclusion criteria, a group of six independent reviewers selected 43 publications from a total of 1958 potentially relevant studies retrieved. Confidence intervals and/or standard errors were calculated and the heterogeneity variance of the survival rates was estimated. RESULTS The survival percentages and standard errors of single-surface and multiple-surface ART restorations in primary posterior teeth over the first 2 years were 94.3% (± 1.5) and 65.4% (± 3.9), respectively; for single-surface ART restorations in permanent posterior teeth over the first 3 years, they were 87.1% (± 3.2); and for multiple-surface ART restorations in permanent posterior teeth over the first 5 years, they were 77% (± 9.0). The mean annual dentine-carious-lesion-failure percentages in previously sealed pits and fissures using ART sealants in permanent posterior teeth over the first 3 and 5 years were 0.9 and 1.9%, respectively. CONCLUSIONS ART single-surface restorations presented high survival percentages in both primary and permanent posterior teeth, whilst ART multiple-surface restorations presented lower survival percentages. ART sealants presented a high-caries-preventive effect. CLINICAL RELEVANCE ART is an effective evidence-based option for treating and preventing carious lesions in primary and permanent posterior teeth.

Abstract
BACKGROUND The aim of this systematic review and meta-analysis was to evaluate the ability of glass ionomer cements (GICs) and resin-based sealants (RBSs) to prevent the occurrence of caries and their retention in standards-based clinical studies. TYPES OF STUDIES REVIEWED The authors conducted a literature search (from database inception through September 20, 2017) to identify studies for inclusion in this systematic review. The authors assessed the quality of the evidence with the modified Jadad scale and performed the meta-analysis by using a random-effects model. RESULTS The authors considered 20 studies on caries prevention and 28 studies on retention that met the inclusion criteria for the meta-analysis. The results of the meta-analysis for caries development showed no significant difference (odds ratio, 0.938; 95% confidence interval, 0.647 to 1.359; P = .734). However, the result for the retention rate showed the advantage of RBSs (odds ratio, 6.006; 95% confidence interval, 3.226 to 11.183; P = .000). CONCLUSIONS AND PRACTICAL IMPLICATIONS There was no difference between the percentage of caries development with use of GICs as fissure sealing material compared with that for the conventional RBSs, but the retention rate of conventional RBSs was much higher than that of the GICs.

Abstract
OBJECTIVES The aim of this study was to compare the caries-preventive effect and the retention rates of sealants prepared with a new modified and a high-viscosity glass-ionomer cement (GIC) in recently erupted first permanent molars. MATERIALS AND METHODS: Fifty-six children (224 teeth) were included in a split-mouth randomised clinical trial. All children had their four first permanent molars sealed with either Clinpro XT Varnish (CXT) or Fuji IX GP FAST (FJ). FJ sealants were placed according to the ART protocol. Retention rates and caries-preventive effect of both materials were assessed clinically after 24 months, and survival curves were created according to the Kaplan-Meier method. For sealant retention rates, analyses were performed according to both the traditional method and modified sealant retention categorisation. RESULTS FJ sealants were retained longer in comparison to CXT sealants (p < 0.05), regardless of the categorisation used. In relation to the caries-preventive effect, no statistically significant differences were observed between materials (p = 0.99). Sealants prepared with the high-viscosity GIC according to the ART protocol survived longer than those prepared with the modified GIC, but both materials were equally effective in preventing cavitated dentine lesions over 24 months. CONCLUSION We concluded that GIC-based sealants are effective in preventing dentine caries lesions.

Abstract
BACKGROUND National Health and Nutrition Examination Survey 2011-2012 data indicated that, in the United States, nearly one-fourth of children and over one-half of adolescents experienced dental caries in their permanent teeth. The purpose of this review was to summarize the available clinical evidence regarding the effect of dental sealants for the prevention and management of pit-and-fissure occlusal carious lesions in primary and permanent molars, compared with a control without sealants, with fluoride varnishes, or with other head-to head comparisons. TYPE OF STUDIES REVIEWED The authors included parallel and split-mouth randomized controlled trials that included at least 2 years of follow-up, which they identified using MEDLINE (via PubMed), Embase, LILACS, the Cochrane Central Register of Controlled Trials, and registers of ongoing trials. Pairs of reviewers independently conducted the selection of studies, data extraction, risk of bias assessments, and quality of the evidence assessments by using the Grading of Recommendations Assessment, Development and Evaluation approach. RESULTS Of 2,869 records screened, the authors determined that 24 articles (representing 23 studies) proved eligible. Moderate-quality evidence suggested that participants who received sealants had a reduced risk of developing carious lesions in occlusal surfaces of permanent molars compared with those who did not receive sealants (odds ratio [OR], 0.15; 95% confidence interval [CI], 0.08-0.27) after 7 or more years of follow-up. When the authors compared studies whose investigators had compared sealants with fluoride varnishes, they found that sealants reduced the incidence of carious lesions after 7 or more years of follow-up (OR, 0.19; 95% CI, 0.07-0.51); however, this finding was supported by low-quality evidence. On the basis of the evidence, the authors could not provide a hierarchy of effectiveness among the studies whose investigators had conducted head-to-head comparisons. The investigators of 2 trials provided information about adverse events, but they did not report any adverse events. CONCLUSIONS AND PRACTICAL IMPLICATIONS Available evidence suggests that sealants are effective and safe to prevent or arrest the progression of noncavitated carious lesions compared with a control without sealants or fluoride varnishes. Further research is needed to provide information about the relative merits of the different types of sealant materials.

Abstract
This paper reviews the literature and discusses the latest updates on the use of pit and fissure sealants. It demonstrates the effectiveness of pit and fissure sealants in preventing caries and the management of early carious lesions. It compares the use of different sealant materials and their indications. It describes the application technique for sealants. It also reviews the cost-effectiveness of sealants as a preventive strategy. From this review and after the discussion of recently published studies on pit and fissure sealants, it is evident that sealants are effective in caries prevention and in preventing the progression of incipient lesions. It is therefore recommended that pit and fissure sealant be applied to high-caries-risk children for optimum cost-effectiveness. It is a highly sensitive technique that needs optimum isolation, cleaning of the tooth surface, etching, and the application of a thin bonding layer for maximum benefit. Recall and repair, when needed, are important to maximize the effectiveness of such sealant use.

Abstract
BACKGROUND Dental sealants were introduced in the 1960s to help prevent dental caries, mainly in the pits and fissures of occlusal tooth surfaces. Sealants act to prevent bacteria growth that can lead to dental decay. Evidence suggests that fissure sealants are effective in preventing caries in children and adolescents compared to no sealants. Effectiveness may, however, be related to caries incidence level of the population. This is an update of a review published in 2004, 2008 and 2013. OBJECTIVES To compare the effects of different types of fissure sealants in preventing caries in occlusal surfaces of permanent teeth in children and adolescents. SEARCH METHODS Cochrane Oral Health's Information Specialist searched: Cochrane Oral Health's Trials Register (to 3 August 2016), the Cochrane Central Register of Controlled Trials (CENTRAL) (the Cochrane Library, 2016, Issue 7), MEDLINE Ovid (1946 to 3 August 2016), and Embase Ovid (1980 to 3 August 2016). We searched ClinicalTrials.gov and the World Health Organization International Clinical Trials Registry Platform for ongoing trials to 3 August 2016. No restrictions were placed on language or date of publication. SELECTION CRITERIA Randomised controlled trials (RCTs) comparing sealants with no sealant or a different type of sealant material for preventing caries of occlusal surfaces of premolar or molar teeth in children and adolescents aged up to 20 years. Studies required at least 12 months follow-up. We excluded studies that compared compomers to resins/composites. DATA COLLECTION AND ANALYSIS Two review authors independently screened search results, extracted data and assessed risk of bias of included studies. We presented outcomes for caries or no caries on occlusal surfaces of permanent molar teeth as odds ratio (OR) or risk ratio (RR). We used mean difference (MD) for mean caries increment. All measures were presented with 95% confidence intervals (CI). We conducted meta-analyses using a random-effects model for comparisons where there were more than three trials; otherwise we used the fixed-effect model. We used GRADE methods to assess evidence quality. MAIN RESULTS We included 38 trials that involved a total of 7924 children; seven trials were new for this update (1693 participants). Fifteen trials evaluated the effects of resin-based sealant versus no sealant (3620 participants in 14 studies plus 575 tooth pairs in one study); three trials with evaluated glass ionomer sealant versus no sealant (905 participants); and 24 trials evaluated one type of sealant versus another (4146 participants). Children were aged from 5 to 16 years. Trials rarely reported background exposure to fluoride of trial participants or baseline caries prevalence. Resin-based sealant versus no sealant: second-, third- and fourth-generation resin-based sealants prevented caries in first permanent molars in children aged 5 to 10 years (at 24 months follow-up: OR 0.12, 95% CI 0.08 to 0.19, 7 trials (5 published in the 1970s; 2 in the 2010s), 1548 children randomised, 1322 children evaluated; moderate-quality evidence). If we were to assume that 16% of the control tooth surfaces were decayed during 24 months of follow-up (160 carious teeth per 1000), then applying a resin-based sealant would reduce the proportion of carious surfaces to 5.2% (95% CI 3.13% to 7.37%). Similarly, assuming that 40% of control tooth surfaces were decayed (400 carious teeth per 1000), then applying a resin-based sealant would reduce the proportion of carious surfaces to 6.25% (95% CI 3.84% to 9.63%). If 70% of control tooth surfaces were decayed, there would be 19% decayed surfaces in the sealant group (95% CI 12.3% to 27.2%). This caries-preventive effect was maintained at longer follow-up but evidence quality and quantity was reduced (e.g. at 48 to 54 months of follow-up: OR 0.21, 95% CI 0.16 to 0.28, 4 trials, 482 children evaluated; RR 0.24, 95% CI 0.12 to 0.45, 203 children evaluated). Although studies were generally well conducted, we assessed blinding of outcome assessment for caries at high risk of bias for all trials (blinding of outcome assessment is not possible in sealant studies because outcome assessors can see and identify sealant). Glass ionomer sealant versus no sealant: was evaluated by three studies. Results at 24 months were inconclusive (very low-quality evidence). One sealant versus another sealant: the relative effectiveness of different types of sealants is unknown (very low-quality evidence). We included 24 trials that directly compared two different sealant materials. Comparisons varied in terms of types of sealant assessed, outcome measures chosen and duration of follow-up. Adverse events: only four trials assessed adverse events. No adverse events were reported. AUTHORS' CONCLUSIONS Resin-based sealants applied on occlusal surfaces of permanent molars are effective for preventing caries in children and adolescents. Our review found moderate-quality evidence that resin-based sealants reduced caries by between 11% and 51% compared to no sealant, when measured at 24 months. Similar benefit was seen at timepoints up to 48 months; after longer follow-up, the quantity and quality of evidence was reduced. There was insufficient evidence to judge the effectiveness of glass ionomer sealant or the relative effectiveness of different types of sealants. Information on adverse effects was limited but none occurred where this was reported. Further research with long follow-up is needed.

Abstract
Fissure sealant retention is traditionally considered as a proxy measure for caries prevention. This study investigated the logic behind this proposition, and its validity. A logical framework of the proposition was established. The mechanism of caries development was transferred into a Directed acyclic graph, and this was used to investigate the logical framework. The sensitivity and specificity of full sealant retention in the prediction of dental carious lesion development and the number of false positive/false negative prediction rates were computed. The sensitivity/specificity was statistically compared to that of random values. A contradiction in the logical framework was identified. The mean sensitivity/specificity was 37.9% (SD = 27.8%) and 67.6% (SD = 28.4%), respectively. When these values were compared against random values (30.5%, SD = 25.7% and 58.7%, SD = 31.6%), a non-significant sensitivity (P = 0.06) and a borderline higher specificity (P = 0.04) were observed. The overall false prediction rate was 33.7%, with 16.9% and 16.8% false negative and false positive predictions, respectively. The sensitivity/specificity was too low and the false prediction rate was too high to consider retention a valid proxy for caries prevention. The logic behind the investigated proposition is flawed, contradicted by the current empirical evidence, and thus invalid.

Abstract
The aim was to test the null-hypothesis that there is no difference in the cumulative survival rate of retained composite resin (CR) sealants and a high-viscosity glass-ionomer Atraumatic Restorative Treatment (ART) sealant in first permanent molars calculated according to the traditional and the modified retention assessment criteria over a period of 3 years. This cluster-randomized controlled clinical trial consisted of 123 schoolchildren, 6-7-years-old. At baseline, high-caries risk pits and fissures of fully erupted first permanent molars were treated with CR and ART sealants. Evaluations were performed after 0.5, 1, 2 and 3 years. Retention was scored for free-smooth surface and for each of three sections into which the occlusal surface had been divided. The modified criterion differed from the traditional in that it determined an occlusal sealant to be a failure when at least one section contained no visible sealant material. Data were analysed according to the PHREG model with frailty correction, Wald-test, ANOVA and t-test, using the Jackknife procedure. The cumulative survival rates for retained CR and ART sealants in free-smooth and occlusal surfaces for both criteria were not statistically significantly different over the 3 years. A higher percentage of retained CR sealants on occlusal surfaces was observed at longer evaluations. Cumulative survival rates were statistically significantly lower for the modified criterion in comparison to the traditional. The modified retention assessment criterion should be used in future sealant-retention studies.

Abstract
The aim of this study was to evaluate and compare for 24 months, the retention and surface characteristics of two pit-and-fissure sealants: Helioseal Clear and Helioseal F (Ivoclar Vivadent). The correlation between the different stages of eruption and sealant retention was also verified. Fifty children aged 6 to 8 years participated in the study, totalizing 153 teeth divided into two groups: HC (Helioseal Clear) and HF (Helioseal F). After 6, 12, 18 and 24 months, a clinical examination was performed by previously calibrated examiners. The surface characteristics and the retention of the sealants (modified RYGE & SNYDER criteria) were assessed. Analyzing the occlusal surface, HC exhibited a statistically significant higher retention at 12 (p=0.0345) and 24 months (p=0.0076). Concerning the surface characteristics, only the superficial discoloration of HC was smaller than HF, during the entire studied period. For all the other characteristics, the results of the Mann-Whitney test were highly significant at different periods (p=0.0000 to 0.0421). The frequency of air bubbles within the sealant surfaces, determined by Chi-square test, was significantly higher in HF (p=0.000:12 and 18 months to p=0.002: 6 and 24 months). HC sealant material exhibited the best performance regarding the retention and surface characteristics on the occlusal surface.

Abstract
OBJECTIVES The null-hypothesis tested was that there was no difference in the frequency of remnants of high-viscosity glass-ionomer sealants left behind in pits and fissures of occlusal surfaces of first permanent molars and that of resin composite and glass-carbomer sealants. MATERIALS AND METHODS Based on the results of a sealant trial, a sample of sealed teeth from which the material had apparently completely disappeared from at least one of the three sections into which the occlusal surface was divided, assessed through visible clinical examination, was also assessed from images of colour photographs and Scanning Electron Microscopy (SEM) as the reference image. The sample size consisted of 112 and 120 teeth from 59 and 98 children at evaluation years 2 and 3 respectively. Two examiners performed the assessments. Fisher's Exact Test was applied to test for the differences between the dependent variable and the sealant groups. RESULTS The remnants of sealant material left in the deeper parts of pits and fissures were assessed from colour photograph and SEM images in five sections at year 2 and in eight sections at year 3. The assessment found no sealant group effect. CONCLUSION The frequency of remnants of glass-ionomer sealant in pits and fissures of occlusal surfaces in first permanent molars is not higher than the frequency of glass-carbomer and resin sealants after 2 and 3 years. CLINICAL RELEVANCE Contrary to the current assumption, there appears to be no significant difference in the frequency of remnants left behind in pits and fissures between glass-ionomer and resin sealants.

Abstract
Resumo Objetivo Este estudo avaliou a microdureza de dois materiais ionoméricos – Glass Carbomer (GC-GCP Dental) e Riva Light Cure (RL-SDI) ‒ em combinação com quatro unidades fotopolimerizadoras (Carbo LED lamp, GCP-Dental; Demi LED curing light, Kerr; Poli Wireless, Kavo; Radii Plus, SDI). Material e método Foram confeccionados 80 corpos de prova seguindo a orientação dos fabricantes, sendo 40 para cada material ionomérico e, para cada 10 corpos de prova, uma das unidades fotopolimerizadoras foi utilizada. Após sete dias de armazenamento em água destilada e temperatura ambiente, os 80 corpos de prova foram submetidos ao teste de microdureza Vickers (microdurômetro HMV 2T). Cinco indentações foram realizadas em cada corpo de prova (centro, extremidades direita e esquerda, e superior e inferior). O ensaio foi realizado sob uma carga de 100 gramas, com tempo de penetração de dez segundos. Resultado Independentemente da unidade fotopolimerizadora, o Riva Light Cure (RL-SDI) apresentou menor microdureza que o material Glass Carbomer (GC-GCP-Dental). A microdureza do Glass Carbomer (GC-GCP-Dental) foi influenciada pelo tipo de unidade fotopolimerizadora utilizada como fonte de calor. A análise de variância e o Teste de Tuckey (p<0,05) mostraram que a interação dos fatores ‘material’ vs. ‘unidade fotopolimerizadora’ (p<0,001) e os fatores principais ‘material’ (p<0,001) e ‘unidade fotopolimerizadora’ (p=0,002) foram estatisticamente significantes. Conclusão O material ionomérico Glass Cabomer (GCP- Dental) apresentou valor de microdureza significativamente superior quando comparado com o cimento de ionômero de vidro modificado por resina Riva Light Cure (SDI), independentemente da unidade fotopolimerizadora utilizada.

Abstract
The aim of this study was to test the hypothesis that the colour photograph method has a higher level of validity for assessing sealant retention than the visual clinical examination and replica methods. Sealed molars were assessed by two evaluators. The scores for the three methods were compared against consensus scores derived through assessing retention from scanning electron microscopy images (reference standard). The presence/absence (survival) of retained sealants on occlusal surfaces was determined according to the traditional and modified categorizations of retention. Sensitivity, specificity, and Youden-index scores were calculated. Sealant retention assessment scores for visual clinical examinations and for colour photographs were compared with those of the reference standard on 95 surfaces, and sealant retention assessment scores for replicas were compared with those of the reference standard on 33 surfaces. The highest mean Youden-index score for the presence/absence of sealant material was observed for the colour photograph method, followed by that for the replica method; the visual clinical examination method scored lowest. The mean Youden-index score for the survival of retained sealants was highest for the colour photograph method for both the traditional (0.882) and the modified (0.768) categories of sealant retention, whilst the visual clinical examination method had the lowest Youden-index score for these categories (0.745 and 0.063, respectively). The colour photograph method had a higher validity than the replica and the visual examination methods for assessing sealant retention.

Abstract
To compare the levels of agreement and the survival rates of sealant retention for different sealing materials over a 2-year period assessed using the visual clinical examination and replica methods, sealant retention data were obtained by visual clinical examination and from replicas of the same sealed tooth at baseline and at 0.5-, 1- and 2-year evaluation points in 407 children and were compared for agreement using kappa coefficients. Survival curves of retained sealants on occlusal surfaces were created using modified categorisation (fully retained sealants and those having all pits and fissures partly covered with the sealant material versus completely lost sealants that included pit and fissure systems that had ≥1 pit re-exposed) according to the Kaplan-Meier method. The kappa coefficient for the agreement between both assessment methods over the three evaluation time points combined was 0.38 (95% confidence interval (CI): 0.35-0.41). More sealant retention was observed from replicas than through visual clinical examination. Cumulative survival curves at the three evaluation times were not statistically significantly higher when assessed from replicas (P=0.47). Using the replica method, more retained sealant material was observed than through visual clinical examination during the 2-year period. This finding did not result in a difference in the survival rates of sealants assessed by the two assessment methods. When replicas cast in die stone are used for assessing sealant retention, the level of reliability of the data is higher than that of data obtained through the commonly used visual clinical examination, particularly if such assessments are conducted over time.

Abstract
OBJECTIVE The hypotheses tested were: the cumulative survival rates of dentin caries lesion-free pits and fissures of ART conventional high-viscosity glass-ionomer sealants with light-curing (high-intensity LED) and glass-carbomer sealants are higher than those of conventional ART sealants and resin-composite sealants after 4 years. METHODS The randomized controlled clinical trial covered 405 children (mean age 8-years). Three dentists placed sealants in pits and fissures of high caries-risk children. Evaluation by two independent evaluators was conducted after 0.5, 1, 2, 3 and 4 years. The Kaplan-Meier survival method, ANOVA and t-test were used in data analyses. RESULTS 1304 first permanent molars were sealed. 12.3% of children and 15.4% of sealants dropped out. 46 re-exposed pits and fissures, 39 (occlusal) 7 (free smooth surfaces), in 42 children developed a dentin carious lesion. The cumulative survival of dentin caries lesion-free occlusal pits and fissures in ART plus LED group (98%) was statistically significantly higher than in the resin-composite group (96.4%) and in the glass-carbomer group (94.5%). The cumulative survival of dentin caries lesion-free occlusal pits and fissures in the glass-carbomer group was statistically significantly lower than that in the conventional ART group (97.3%). For the free smooth surfaces, there was no statistically significantly difference among the four sealant groups. SIGNIFICANCE Light-cured ART conventional high-viscosity glass-ionomer sealants prevented the occurrence of dentin cavities best.

Abstract
PURPOSE Dental sealant materials may intraorally release their components, including bisphenol-A (BPA), but long-term health effects are uncertain. The New England Children's Amalgam Trial (NECAT) found that composite restorations were associated with psychosocial, but not neuropsychological or physical, outcomes. The previous analysis did not consider sealants and preventive resin restorations (PRRs), which were routinely placed. The purpose of this analysis was to examine sealant/PRR exposure in association with psychosocial and other health outcomes. METHODS NECAT recruited 534 six- to 10-year-olds and provided dental care during a five-year follow-up. Annually, examiners conducted psychosocial and neuropsychological tests and measured body mass index (BMI) and fat percentage (BF%). Associations between surface years (SY) of sealants/PRRs and outcomes were tested using multivariable models. RESULTS Cumulative exposure level to sealants and/or PRRs was not associated with psychosocial assessments (eg, total problems: Child Behavior Checklist, 10-SY β=-0.2 ± 0.3, P=.60) or neuropsychological tests (eg, full-scale IQ, 10-SY β=0.1 ± 0.2, P=.60). There were no associations for changes in BMI-for-age z-score (P=.40), BF% (girls 10-SY β=-0.2 ± 0.3; boys 10-SY β=-0.1 ± 0.3), or menarche (10-SY hazard ratio=0.91, 95% confidence interval=0.83-1.01, P=.08). CONCLUSIONS This study showed no associations between exposure level of dental sealants or PRRs and behavioral, neuropsychological, or physical development in children over 5-years.

Glass ionomer ART sealants in Chinese school children-6-year results. J Dent 2013; 41:764-70.

Abstract
OBJECTIVE To evaluate longitudinally ART sealants placed in Chinese school children under field conditions. METHOD 191 ART sealants were placed in 140 children, aged 11-14 years, by five assistant dentists in four secondary schools in Deyang, Sichuan Province, China. Teeth selected for sealing were those with pits and fissures that were deep or showing early enamel caries. Teeth were excluded if there was obvious cavitation extending into dentine. Standard instruments and procedures for ART sealants were used. The material used was a high-viscosity glass-ionomer (Ketac-Molar, 3MESPE) that was inserted into the pits and fissures with the "press-finger" technique. The status of the sealants was evaluated annually over 6 years after placement by the same examiner who was not involved in the placement of the sealants using explorers, mouth-mirrors and an intra-oral fibre-optic light. No missing sealants were replaced during the study. RESULTS 107 sealants (56% of the original) were examined after 6 years. The cumulative survival rates of the sealants (partially or fully retained) after 2, 4 and 6 years were 79%, 68% and 59%, respectively. Caries prevention lagged the fall in sealant survival but remained high throughout the study period, being over 90% in the first 4 years and 85% after 6 years. CONCLUSIONS ART sealants placed under field conditions in Chinese schoolchildren have a high retention rate. Missing sealants should be replaced to maintain their preventive efficacy. CLINICAL SIGNIFICANCE The sealing of pits and fissures can be an effective caries preventive approach. Resin-based sealants have the disadvantage in that they require an optimal level of moisture control during placement. In children and in outreach situations glass ionomer ART sealants, which are more moisture tolerant, can offer a viable alternative.

Abstract
BACKGROUND Dental sealants were introduced in the 1960s to help prevent dental caries in the pits and fissures of mainly the occlusal tooth surfaces. Sealants act to prevent the growth of bacteria that can lead to dental decay. There is evidence to suggest that fissure sealants are effective in preventing caries in children and adolescents when compared to no sealants. Their effectiveness may be related to the caries prevalence in the population. OBJECTIVES To compare the effects of different types of fissure sealants in preventing caries in permanent teeth in children and adolescents. SEARCH METHODS We searched the Cochrane Oral Health Group's Trials Register (to 1 November 2012); the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2012, Issue 7); MEDLINE via OVID (1946 to 1 November 2012); EMBASE via OVID (1980 to 1 November 2012); SCISEARCH, CAplus, INSPEC, NTIS and PASCAL via STN Easy (to 1 September 2012); and DARE, NHS EED and HTA (via the CAIRS web interface to 29 March 2012 and thereafter via Metaxis interface to September 2012). There were no language or publication restrictions. We also searched for ongoing trials via ClinicalTrials.gov (to 23 July 2012). SELECTION CRITERIA Randomised or quasi-randomised controlled trials of at least 12 months duration comparing sealants for preventing caries of occlusal or approximal surfaces of premolar or molar teeth with no sealant or different type of sealant in children and adolescents under 20 years of age. DATA COLLECTION AND ANALYSIS Two review authors independently screened search results, extracted data and assessed trial quality. We calculated the odds ratio (OR) for caries or no caries on occlusal surfaces of permanent molar teeth. For trials with a split-mouth design, the Becker-Balagtas odds ratio was used. For mean caries increment we used the mean difference. All measures are presented with 95% confidence intervals (CI). The quality of the evidence was assessed using GRADE methods. We conducted the meta-analyses using a random-effects model for those comparisons where there were more than three trials in the same comparison, otherwise the fixed-effect model was used. MAIN RESULTS Thirty-four trials are included in the review. Twelve trials evaluated the effects of sealant compared with no sealant (2575 participants) (one of those 12 trials stated only number of tooth pairs); 21 trials evaluated one type of sealant compared with another (3202 participants); and one trial evaluated two different types of sealant and no sealant (752 participants). Children were aged from 5 to 16 years. Trials rarely reported the background exposure to fluoride of the trial participants or the baseline caries prevalence.- Resin-based sealant compared with no sealant: Compared to control without sealant, second or third or fourth generation resin-based sealants prevented caries in first permanent molars in children aged 5 to 10 years (at 2 years of follow-up odds ratio (OR) 0.12, 95% confidence interval (CI) 0.07 to 0.19, six trials (five published in the 1970s and one in 2012), at low risk of bias, 1259 children randomised, 1066 children evaluated, moderate quality evidence). If we were to assume that 40% of the control tooth surfaces were decayed during 2 years of follow-up (400 carious teeth per 1000), then applying a resin-based sealant will reduce the proportion of the carious surfaces to 6.25% (95% CI 3.84% to 9.63%); similarly if we were to assume that 70% of the control tooth surfaces were decayed (700 carious teeth per 1000), then applying a resin-based sealant will reduce the proportion of the carious surfaces to 18.92% (95% CI 12.28% to 27.18%). This caries preventive effect was maintained at longer follow-up but both the quality and quantity of the evidence was reduced (e.g. at 48 to 54 months of follow-up OR 0.21, 95% CI 0.16 to 0.28, four trials (two studies at low risk of bias and two studies at high risk of bias), 482 children evaluated; risk ratio (RR) 0.24, 95% CI 0.12 to 0.45, one study at unclear risk of bias, 203 children evaluated).- Glass ionomer sealant compared with no sealant: There is insufficient evidence to make any conclusions about whether glass ionomer sealants, prevent caries compared to no sealant at 24-month follow-up (mean difference in DFS -0.18, 95% CI -0.39 to 0.03, one trial at unclear risk of bias, 452 children randomised, 404 children evaluated, very low quality evidence).- Sealant compared with another sealant: The relative effectiveness of different types of sealants remained inconclusive in this review. Twenty-one trials directly compared two different sealant materials. Several different comparisons were made according to type of sealant, outcome measure and duration of follow-up. There was great variation with regard to comparisons, outcomes, time of outcomes reported and background fluoride exposure if this was reported.Fifteen trials compared glass ionomer with resin sealants and there is insufficient evidence to make any conclusions about the superiority of either of the two materials. Although there were 15 trials the event rate was very low in many of these which restricted their contribution to the results.Three trials compared resin-modified glass ionomer with resin sealant and reported inconsistent results.Two small low quality trials compared polyacid-modified resin sealants with resin sealants and found no difference in caries after 2 years.- Adverse effects: Only two trials mentioned adverse effects and stated that no adverse effects were reported by participants. AUTHORS' CONCLUSIONS The application of sealants is a recommended procedure to prevent or control caries. Sealing the occlusal surfaces of permanent molars in children and adolescents reduces caries up to 48 months when compared to no sealant, after longer follow-up the quantity and quality of the evidence is reduced. The review revealed that sealants are effective in high risk children but information on the magnitude of the benefit of sealing in other conditions is scarce. The relative effectiveness of different types of sealants has yet to be established.

Abstract
Background The atraumatic restorative treatment (ART) approach was born 25 years ago in Tanzania. It has evolved into an essential caries management concept for improving quality and access to oral care globally. Results Meta-analyses and systematic reviews have indicated that the high effectiveness of ART sealants using high-viscosity glass ionomers in carious lesion development prevention is not different from that of resin fissure sealants. ART using high-viscosity glass ionomer can safely be used to restore single-surface cavities both in primary and in permanent posterior teeth, but its quality in restoring multiple surfaces in primary posterior teeth cavities needs to be improved. Insufficient information is available regarding the quality of ART restorations in multiple surfaces in permanent anterior and posterior teeth. There appears to be no difference in the survival of single-surface high-viscosity glass-ionomer ART restorations and amalgam restorations. Discussion The use of ART results in smaller cavities and in high acceptance of preventive and restorative care by children. Because local anaesthesia is seldom needed and only hand instruments are used, ART is considered to be a promising approach for treating children suffering from early childhood caries. ART has been implemented in the public oral health services of a number of countries, and clearly, proper implementation requires the availability of sufficient stocks of good high-viscosity glass ionomers and sets of ART instruments right from the start. Textbooks including chapters on ART are available, and the concept is being included in graduate courses at dental schools in a number of countries. Recent development and testing of e-learning modules for distance learning has increasingly facilitated the distribution of ART information amongst professionals, thus enabling more people to benefit from ART. However, this development and further research require adequate funding, which is not always easily obtainable. The next major challenge is the continuation of care to the frail elderly, in which ART may play a part. Conclusion ART, as part of the Basic Package of Oral Care, is an important cornerstone for the development of global oral health and alleviating inequality in oral care.

Abstract
OBJECTIVES The aim of the present study was to investigate the caries-preventive effect of sealants produced with a high-viscosity glass-ionomer with an elevated powder-liquid ratio (ART), of having energy added to this glass-ionomer, and that of glass-carbomer, in comparison to that of resin composite sealants. METHODS The randomized controlled trial covered 407 children, with a mean age of 8 years. At a school compound three dentists placed sealants in pits and fissures of high caries-risk children. Evaluation by two independent evaluators was conducted after 0.5, 1 and 2 years. The Kaplan-Meier survival method, ANOVA and t-test were used in analyzing the data. RESULTS 1352 first permanent molars were sealed. 6.6% of children and 6.8% of sealants dropped out within 2 years. 27 re-exposed pits and fissures, 20 in occlusal and 7 in smooth surfaces, in 25 children, developed a dentin carious lesion. The cumulative survival of dentin carious lesion-free pits and fissures in the glass-carbomer sealant group was statistically significantly lower (97.4%) than those in the high-viscosity glass-ionomer with energy supplied (99%) and the resin-composite (98.9%) sealant groups. There was no statistically significant difference in the cumulative survival of dentin carious lesion-free pits and fissures, between the high-viscosity glass-ionomer with (99%) and without (98.3%) energy supplied sealant groups, after 2 years. SIGNIFICANCE The survival of dentin carious lesion-free pits and fissures was high in all sealant types. More dentin carious lesions were observed in the glass-carbomer sealant group.
