Background/Objectives Pit and fissure caries constitute a predominant portion, approximately 90% in permanent posterior teeth and 44% in primary teeth among children and adolescents. Among various preventive modalities, pit and fissure sealants play a pivotal role in safeguarding these vulnerable areas. Categorized by materials such as glass ionomer, composites, and polyacid-modified glass ionomers, these sealants offer effective protection. This study aims to evaluate the efficacy of glass ionomer-based pit and fissure sealants in terms of retention rate at 12-month post-procedure period in permanent first molars. Methodology This study was conducted at the Department of Operative Dentistry, Nishtar Institute of Dentistry, Multan, Pakistan. Fifty-six children, aged 7 to 12 years, presenting with pit and fissure caries in permanent first molar teeth were enrolled. Glass ionomer sealant was meticulously applied to the affected pits and fissures. The efficacy was assessed after 12 months based on predefined criteria. Results The age of participants ranged from 7 to 12 years, with a mean age of 9.24 ± 1.38 years. Among the 56 patients, 23 (41.2%) were male and 33 (58.8%) were female. Sealant retention was noted in 31 (55.35%) patients, while 25 (44.65%) experienced sealant loss. In the 7 to 9-year age group, 19 demonstrated complete sealant retention, whereas in the 10 to 12-year age group, 12 exhibited complete retention. Concerning gender distribution, 17 males and 14 females exhibited complete sealant retention. Conclusion Glass ionomer-based sealants demonstrate excellent properties for pit and fissure sealing owing to their low technique sensitivity, cost-effectiveness, and favorable retention rates. Therefore, they represent an optimal choice for this preventive dental procedure.

Journal of Pharmacy & Bioallied Sciences Feb 2024In this study, the retention rates of four different pit and fissure sealant materials on the first permanent molars were clinically assessed and compared.
OBJECTIVE
In this study, the retention rates of four different pit and fissure sealant materials on the first permanent molars were clinically assessed and compared.
MATERIALS AND METHODS
A total of 120 kids aged 7 to 10 participated in a randomized controlled experiment. On their first permanent teeth, the subjects each got one of the four sealant materials (A, B, C, or D). Over the course of 24 months, the retention rates were evaluated every 6 months. The Chi-square test and Kaplan-Meier survival analysis were used for statistical analysis.
RESULTS
At 6, 12, 18, and 24 months, the following retention rates were observed overall: A (85%, 78%, 65%, 52%), B (90%, 82%, 70%, 60%), C (78%, 70%, 55%, 42%), and D (95%, 88%, 75%, 62%). At each time point, the sealant materials showed significant variations in retention rates ( 0.05). While sealants A and C showed lower retention rates, sealant D showed the best retention rates, followed by sealant B.
CONCLUSION
This study shows that different materials have different retention rates for pit and fissure sealants on first permanent molars. Higher retention rates for sealants D and B suggest that they may be superior than sealants A and C. These results highlight how crucial it is to choose the right sealant materials to guarantee long-term retention and effectiveness in avoiding dental cavities.

Meta-Analysis
Characterization of the oral microbiota and the relationship of the oral microbiota with the dental and periodontal status in children and adolescents with nonsyndromic cleft lip and palate. Systematic literature review and meta-analysis.
OBJECTIVE
To identify the characteristics of the oral microbiota and the relationship of the dental caries and periodontal status in patients aged 0 to 18 years with non-syndromic cleft lip and palate (CLP).
MATERIALS AND METHODS
A systematic review of the literature was carried out. Five databases were consulted, including publications in English, Spanish and Portuguese. The evaluations of the quality of the observational studies and the experimental studies were carried out with the Newcastle-Ottawa scale and CONSORT guidelines, respectively. The risk of bias of the studies was determined using Rev Manager 5.4, and 5 publications were meta-analyzed.
RESULTS
The cariogenic microbiota of children and adolescents with cleft lip and palate was similar to that of children without clefts, although with higher counts of Streptococcus mutans and Lactobacillus spp. The periodontopathogenic microbiota was related to the presence of Campylobacter spp, Fusobacterium spp, Fusobacterium nucleatum, Prevotella intermedia/nigrescens, Parvimonas micra and Porphyromonas gingivalis, considered microorganisms with high pathogenic capacity. Heterogeneity was shown in relation to the microbiota and the type of fissure, presenting numerous microorganisms associated with the pre- and post-surgical condition (cheilorrhaphy and palatorrhaphy) such as Staphylococcus aureus, Streptococcus beta hemolyticus, Klebsiella pneumoniae and Klebsiella oxytoca, Moraxella catarrhalis, Candida spp, Candida albicans, Candida krusei and Candida tropicalis. The meta-analysis revealed that patients with cleft lip and palate were 2.03 times more likely to have caries than the control group (p<0.005).
CONCLUSION
In the microbiota, there was a great diversity of microorganisms that can vary according to the type of fissure and surgical interventions predisposing patients to a greater probability of dental caries, it is important to take into account the technique used to describe the oral microbiota in order to be able to compare the different studies.
CLINICAL RELEVANCE
Studying the microbiota and the relationship of dental caries and periodontal status in children and adolescents with cleft lip and palate can facilitate the comprehensive care of patients with these conditions.

Conventional resin-based sealants release minimal fluoride ions (F) and lack antibacterial activity. The objectives of this study were to: (1) develop a novel bioactive sealant containing calcium fluoride nanoparticles (nCaF) and antibacterial dimethylaminohexadecyl methacrylate (DMAHDM), and (2) investigate mechanical performance, F recharge and re-release, microleakage, sealing ability and cytotoxicity. Helioseal F served as commercial control. The initial F release from sealant containing 20% nCaF was 25-fold that of Helioseal F. After ion exhaustion and recharge, the F re-release from bioactive sealant did not decrease with increasing number of recharge and re-release cycles. Elastic modulus of new bioactive sealant was 44% higher than Helioseal F. The new sealant had excellent sealing, minimal microleakage, and good cytocompatibility. Hence, the nanostructured sealant had substantial and sustained F release and antibacterial activity, good sealing ability and biocompatibility. The novel bioactive nCaF sealant is promising to provide long-term F ions for caries prevention.

BACKGROUND
Dental sealants are effective for the prevention of caries in children at elevated risk levels, and increasing the proportion of children and adolescents who have dental sealants on 1 or more molars is a Healthy People 2030 objective. Electronic health record (EHR)-based clinical decision support systems (CDSSs) have the ability to improve patient care. A dental quality measure related to dental sealant placement for children at elevated risk of caries was targeted for improvement using a CDSS.
METHODS
A validated dental quality measure was adapted to assess a patient's need for dental sealant placement. A CDSS was implemented to advise care team members whether a child was at elevated risk of developing caries and had sealant-eligible first or second molars. Data on dental sealant placement at examination visits during a 5-year period were analyzed, including 32 months before CDSS implementation and 28 months after CDSS implementation.
RESULTS
From January 1, 2018, through December 31, 2022, the authors assessed 59,047 examination visits for children at elevated risk of developing caries and with sealant-eligible teeth. With the implementation of a CDSS and training to support the clinical care team members in September 2020, the appropriate placement of dental sealants at examination visits increased from 27% through 60% (P < .00001).
CONCLUSIONS
Integration of a CDSS into the EHR as part of a quality improvement program was effective in increasing the delivery of sealants in eligible first and second molars of children aged 5 through 15 years and considered at high risk of developing caries.
PRACTICAL IMPLICATIONS
An EHR-based CDSS can be implemented to improve standardization and provide timely and appropriate patient care in dental practices.

BACKGROUND
Sealing dental pits and fissures with resin-based sealants effectively prevents occlusal dental caries. The effectiveness of resin-based pit and fissure sealants relies on maintaining a strong bond between the sealant and the enamel.
OBJECTIVE
This study compared the micro-tensile bond strength (μTBS) of a conventional resin-based sealant (Clinpro™) and a hydrophilic resin-based sealant (Embrace™ WetBond™) when applied to intact, aprismatic human enamel.
METHODS
Forty extracted permanent premolar and molar teeth were divided into two groups and paired by tightly approximating two buccal surfaces to create an artificial enamel groove (fissure). Fissure sealants (Clinpro™ and Embrace™ WetBond™) were applied to the artificial enamel 'grooves' in each group. The specimens were then cut into beams with a cross-sectional area of 1 mm and tested for the micro-tensile bond strength (μTBS). Fractured surfaces of samples were examined under a conventional microscope to identify the failure modes. Two specimens from each group were prepared and observed under a scanning electron microscope (SEM). Mann-Whitney U and Fischer-Freeman-Holton exact tests were used to test the statistical differences between the fissure sealants.
RESULTS
The μTBS mean ± SD for Clinpro™ was 16.43 ± 7.08, and 10.57 ± 6.64 for Embrace™ WetBond™. There was a statistically significant difference in μTBS between Embrace™ WetBond™ and Clinpro™ (p < 0.001). There was no association between fissure sealant and failure modes (p = 0.922).
CONCLUSION
Clinpro™ showed higher μTBS to enamel than Embrace™ WetBond™. Further studies are needed to conclude the clinical effectiveness of these sealants.

INTRODUCTION
The role of sealants for pits and fissures has been emphasized in caries prevention. Considering the advantages of a surface sealer and the effects of its application over restorative materials; the study is aimed at evaluating two pit and fissure sealants with a nanofilled resin coating.
MATERIALS AND METHODS
In this double-blinded study, a total of 60 caries-free extracted third molars were collected and divided into two groups of 30 each receiving either a resin-based sealant (Helioseal F) or a glass ionomer-based sealant (GC Fuji VII). Each sample was then applied with GCoat Plus surface sealer. 15 samples each containing GC Fuji VII and 15 containing Helioseal F were then subjected to wear. Another 15 samples of GC Fuji VII and 15 of Helioseal F were subjected to compressive load.
RESULTS
On assessing the wear strength, the weight loss in group I (resin sealant with surface sealer) was 1.73 ± 0.50 (μg) which was statistically significant ( = 0.023). There was no significant difference in comparing the wear depth between both groups. There was a high statistically significant difference when assessing the compressive strength, group II (glass ionomer sealant with surface sealer) had 3566.4 ± 757 (μm) when compared to group I (resin sealant with surface sealer) 1568.53 ± 680 ( ≤ 0.01).
CONCLUSION
Sealants are known for their poor retention and keeping that in mind we designed this study to evaluate the physical properties of sealants with a resin coating over them. Within the limitations of this study, the conclusions are glass ionomer sealant showed greater resistance to wear when compared to the resin-based sealant and the resin-based sealant showed higher compressive strength values than the glass ionomer sealant.

Introduction In modern dentistry, the focus is more on preventing caries than on treating it, which helps preserve the tooth structure. Pit and fissure sealants (PFS) are the most effective methods for providing a mechanical barrier and avoiding the accumulation of dental plaque in deep pits and fissures, thereby preventing occlusal caries. The present study was conducted to compare the efficiency of dentin bonding agents (DBA) with or without fissurotomy in reducing microleakage before PFS placement. Materials and methods A total of 48 freshly extracted premolars were randomly divided into four groups as follows: Group 1, the conventional technique of PFS (Clinpro, 3M ESPE sealant); Group 2, fissurotomy performed before PFS placement; Group 3, Scotchbond Universal Adhesive (3M ESPE DBA) applied before PFS placement; and Group 4, fissurotomy along with DBA was used before PFS placement. The teeth were subjected to thermocycling followed by dye penetration using a 1% solution of methylene blue for 24 hours. All teeth were then assessed for microleakage by a qualitative method using a stereomicroscope at 40X and depth of dye penetration by image analysis. The Kruskal-Wallis test followed by Dunn's test was used for intergroup comparisons of microleakage scores, and ANOVA followed by Tukey's test was used for intergroup comparisons of the depth of dye penetration. These analyses were conducted using statistical software (SPSS version 22, Chicago, IL, USA). Results Statistically significant differences were observed between the groups in terms of the microleakage scores and depth of dye penetration (p<0.05). The group 4 showed a minimum microleakage score (0.50±0.52), and maximum scores were observed in Group 1 (2.16±0.71). Group 2 showed insignificant differences with groups 3 and 4 for depth of dye penetration (p>0.05). Statistically significant differences were observed between groups 1 and 2, groups 1 and 4, and groups 3 and 4 for the microleakage score (p<0.05). Conclusion Fissurotomy with or without DBA significantly reduced microleakage before the PFS placement. Prior use of fourth-generation DBA significantly reduced microleakage compared with PFS placement without the use of DBA.

OBJECTIVE
To improve oral health disparities and outcomes among US children impacted by dental caries, there is a need to understand the cost-effectiveness of a targeted, risk-based versus universal-based approach for caries prevention.
METHODS
Health and economic outcomes were simulated in a cohort of 50,000 US children aged 1-18 years, comparing current practice (CP) to risk-based-prevention (RBP) and prevention-for-all (PFA) strategies using health care sector and limited societal perspectives. Prevention included biannual oral health exams and fluoride varnish application, and one-time dental sealant placement. The primary outcome is the cost-effectiveness ratio (ICER), defined as the additional cost per quality-adjusted life year (QALY) gained when comparing each strategy to the next least costly one.
RESULTS
For RBP compared to CP, the ICER was US$83,000/QALY from the health care sector perspective; for PFA compared to RBP the ICER was US$154,000/QALY. Using a limited societal perspective that includes caregiver time spent attending dental or medical setting visits, RBP compared to CP yielded a ratio of $119,000/QALY and PFA compared to RBP was $235,000/QALY. Results were most sensitive to changes in the probability of pain from an episode of dental caries, costs for prevention and restoration, and the loss in health-related quality of life due to dental caries pain. Scenario analyses evaluating a reduced intensity of prevention services yielded lower ICERs.
CONCLUSION
Using a risk-based approach that identifies and targets children at increased risk for dental caries to guide the delivery of prevention services represents an economic value similar to other pediatric prevention programs.
