Assessment of the Radiopacity of Different Fissure Sealants Compared to Dental Hard Tissues

Aim: The radiopacity of dental materials is crucial for assessing the radiographic success of restorations and can significantly influence clinicians' choice of materials. The objective of our study is to compare the radiopacity of five fissure sealants with that of compomer, composite, glass ionomer filling, and dental hard tissues using digital imaging techniques. Material and Method: Five different fissure sealants (Fuji Triage, BeautiSealant, Grandio Seal, Helioseal F Plus, Embrace Wetbond), compomer (Compoglass F), composite (Solare X), and glass ionomer filling (Equa Forte) materials were prepared as 5 samples each in disk form with a thickness of 2 mm. As controls, sections of primary and permanent teeth with a thickness of 2 mm, along with an aluminum step wedge were utilized. The mean gray values of the samples were measured using Image J software, and the equivalent aluminum thickness was subsequently determined. Statistics analysis using Kruskal-Wallis test at p<0.05. Results: The equivalent aluminum thicknesses related to the radiopacity of fissure sealants are ranked as follows: Fuji Triage (5.2±0.2) > Grandio Seal (3.9±0.2) = permanent tooth enamel (3.7±0.2) = Embrace Wetbond (3.6±0.6) = primary tooth enamel (3.6±0.3) = BeautiSealent (2.1±0.3) > Helioseal F Plus (1.1±0) (p<0.05). The radiopacity equivalent aluminum thicknesses of restorative materials are ranked as follows: Compoglass F (7.3±0.4) > Solare X (4.7±0.3) = Equa Forte (4.4±0.4) = permanent tooth enamel (3.7±0.2) = primary tooth enamel (3.6±0.3) (p<0.05). Conclusion: Materials like Fuji Triage and Compoglass F exhibit high radiopacity values, which can significantly aid clinical monitoring and restoration success.

Evaluation of Microleakage of Different Types of Pit and Fissure Sealants: An In Vitro Comparative Study.

Compare and evaluate the microleakage of different types of pit and fissure sealants, 3M ESPE Clinpro, GC Fuji Triage Capsule, and 3M ESPE Filtek Z350 XT. A total of 54 freshly extracted maxillary and mandibular premolar teeth were used and randomly divided into three groups of 18 teeth each, and the following pit and fissure sealants were used: group I-Clinpro, group II-GC Fuji Triage Capsule, and group III-Filtek Z350 XT. Samples underwent thermocycling at 5° and 55°C with a dwell time of 10 seconds for 250 cycles. The apices of the teeth were sealed with impression compound, and two coats of fingernail polish were applied and immersed in 5% methylene blue dye for 24 hours and then sectioned. The sectioned specimens were then analyzed at 4× magnification under a stereomicroscope for dye penetration and were evaluated based on Williams and Winters' criteria. The data were collected for statistical analysis. Descriptive statistics included mean, standard deviation (SD), frequency, and percentage. Inferential statistics included the Chi-squared test and one-way analysis of variance (ANOVA), followed by the post hoc Tukey's test. The level of significance was set at 0.05 at a 95% confidence interval, and the results revealed that the mean difference of the sealants was GC Fuji Triage (2.1667), Clinpro (0.7778), and Filtek Z350 XT (0.1667). Filtek Z350 XT exhibited the least microleakage when compared to Clinpro and GC Fuji Triage, with their mean difference statistically significant. Hence, Filtek Z350 XT can be a promising sealant and a restorative material. Prabahar T, Chowdhary N, Konkappa KN, et al.

Evaluation of the marginal integrity of various pit and fissure sealants.

To evaluate the marginal integrity of various pit and fissure sealants subjected to different application methods. A total of 253 non-carious human third molars extracted and randomly divided into two groups according to the preparation method employed: invasive or non-invasive. Eight fissure sealant materials were tested: nano-filled flowable composite (Filtek Ultimate Flow), nanohybrid flowable composite (GrandioSo Flow), micro-hybrid flowable composite (Majesty Flow), resin-based unfilled fissure sealant (ClinPro Sealant), resin-based filled fissure sealant (Fissurit FX), resin-based highly filled fissure sealant (GrandioSeal), giomer-based fissure sealant (BeautiSealant), and glass ionomer-based fissure sealant (Fuji Triage). Samples were subjected to two-year cyclic thermo-mechanical and brushing simulations. Two observers quantitatively evaluated the restoration margins and classified them as either "permanent restoration edge", or if a gap larger than 250 μm was evident, "gapping at the restoration edge". The extent of the gap was recorded as a percentage relative to the total length of the restoration edge. The baseline marginal adaptation had no significant effect on the marginal adaptation (P > 0.05). However, the preparation method and type of fissure sealant material had a significant impact on the marginal adaptation (P < 0.05). On the basis of quantitative analysis, the highest marginal integrity was observed for flowable composites, whereas the lowest was observed for glass ionomer-based fissure sealant.

Dentinhaftung bioaktiver Füllungsmaterialien für die Kinderzahnheilkunde

Aim: Bioactive materials are of interest for dental restoration in children with high caries risk. An important parameter for clinical success is durable adhesion to tooth hard tissues. Therefore, the present study evaluated dentin bonding behavior of two bioactive materials (ACTIVA BioACTIVE-RESTORATIVE [Acti, Pulpdent, Watertown, MA, USA] using All Bond Universal [BISCO, Schaumburg, IL, USA], and Cention N bonded with Adhese Universal [Cent, Ivoclar Vivadent, Schaan, Liechtenstein]) compared to a bonded resin composite (Filtek Z250 [FZ250, 3M Oral Care Dental Products, St. Paul, MN, USA] with OptiBond FL [Kerr, Biberach, Deutschland]) and a conventional glass ionomer cement (Fuji Triage pink [FTp, GC Corporation, Tokyo, Japan]) using Cavity Conditioner (GC Europe, Löwen, Belgien).Materials and methods: Twenty-eight caries-free third molars were randomly assigned to four groups (n = 7). Crowns were ground flat to expose dentin. Specimens were pretreated according to the manufacturers' instructions and built-up in 0.5-2 mm layers with composite. After storage (24 h at 37 °C in distilled water), specimens were cut into resin-dentin beams (0.36 mm2 for Acti, Cent, and FZ250; 1 mm2 for FTp) and subjected to microtensile bond strength testing. Additional micromorphological analyses were done using both light and scanning electron microscopy. Statistical appraisal was carried out using one-way analysis of variance (ANOVA; modified least significant difference [LSD] test; p <0.05). Results: Dentin bond strengths were (in MPa, numbers I-III indicate significant differences between groups): FZ250: 63.9 ± 8.3 (I); Acti: 52.1 ± 8.2 (II); Cent: 51.4 ± 10.9 (II); FTp: 3.7 ± 0.9 (III). A pronounced hybrid layer was only found in FZ250. The investigated bioactive restorative materials showed lower dentin adhesion compared to the bonded resin composite, but 13-fold higher values than the GIC (FTp).Conclusion: When adhesively bonded, the bioactive materials under investigation exhibited good dentin bonding behavior. In minimally invasive restorations, we recommend using them with a separate bonding step. However, further studies must show whether this impairs the caries-inhibiting, bioactive effect of the materials.

Caries-inhibiting Effect of Microencapsulated Active Components in Pit and Fissure Sealants.

The aim of the present in vitro study was to examine the caries-inhibiting effect of a pit and fissure sealant (PFS) containing ion-releasing microcapsules under cariogenic conditions in a biofilm artificial mouth. Forty-eight human third molars were divided into four groups (n=12 per group). Fissures were extended with burs and sealed with experimental PFS. The four groups of specimens were treated as follows: 1) EPFS 1: EPFS (Premier Dental) of increasing viscosity, containing microcapsules loaded with remineralizing agents (calcium, phosphate, and fluoride ions); 2) US: fluoride-releasing PFS (UltraSeal XT plus, UltraDent Products, South Jordan, UT, USA); 3) EPFS 2: experimental PFS of constant viscosity containing microcapsules loaded with calcium, phosphate, and fluoride ions; and 4) FT: glass ionomer cement (GIC) (GC Fuji Triage CAPSULE WHITE glass ionomer cement, GC Europe NV, Leuven, Belgium). FT and US were used as control groups. EPFS 1 and EPFS 2 were the experimental groups. Specimens were stored in distilled water for 14 days at 37°C, subjected to 10,000 thermocycles (5°C and 55°C) and finally exposed to microbiological cycling in a Streptococcus mutans-based artificial mouth for 10 days. Replicas were made for scanning electron microscopic (SEM) evaluation and specimens were cut for fluorescence microscopy. Overall demineralization depths at the margin of Fuji Triage were significantly shallower than in the other groups (p<0.05). Overall demineralization depths adjacent to the experimental pit and fissure sealant EPFS 2 (59±15 μm) were comparable to the values of the resin-based pit and fissure sealant UltraSeal XT plus (58±10 μm, p≥0.05). SEM revealed surface roughness of the GIC-based PFS. The experimental PFS with microcapsules containing active components for remineralization did not show a caries-inhibiting effect compared to a fluoride-releasing resin-based PFS. Lower demineralization depths adjacent to GIC sealants indicate an anticariogenic effect through fluoride ion release.

ОNE-YEAR CLINICAL EVALUATION OF THE CARIES-PREVENTIVE EFFECT OF GLASS-IONOMER SEALANT ON NEWLY ERUPTED FIRST PERMANENT MOLARS IN CHILDREN

Background: Dental sealant is a material that is applied to pits and fissures in order to prevent the occurrence of occlusal dental caries. The caries-prophylactic effect of sealants on a glass-ionomer basis has not been sufficiently studied, which motivates us to conduct our research. Purpose; To monitor the caries-preventive effect of a glass-ionomer-based sealant after silanization of the newly erupted first permanent molars in children aged 5-6 years. Materials and methods: We started the study with 78 healthy, newly erupted first permanent molars (silanized with Fuji triage, GC), the follow-up was performed at 3,6 and 12 months by visual method on the ICDAS II system, diagnostics under magnification using VistaCam Macro and modified Ryge criteria. After recoding the data obtained from monitoring the occlusal surfaces of the newly erupted first permanent molars, we performed a frequency analysis of the data depending on the absence or presence of caries. Results: In the group of 5-6-year-olds after the application of glass-ionomer-based sealant in the newly erupted first permanent molars, one year after application of the sealant, we assessedver 95% of the examined surfaces as healthy with all diagnostic methods that we used. Conclusion: Glass-ionomer cements used for silanization are the main tool of choice when it is impossible to control moisture, as is the case with newly erupted molars. Despite their significantly low retention, they provide an excellentaries-prophylactic effect.

Caries-Preventive Effect and Retention of Glass-Ionomer and Resin-Based Sealants: A Randomized Clinical Comparative Evaluation.

Background Deep fissures are highly unprotected from the development of caries. Resin-based materials and glass-ionomer cements for sealing fissures are useful in caries control through physical barrier formation, which prohibits metabolic exchange between fissure microorganisms. Retention is one of the most critical properties of fissure sealants. This in vivo study is aimed at comparing and evaluating the clinical efficacy of resin and glass ionomer-based fissure sealants on first permanent molars with follow-ups at 6-, 12-, and 18-month intervals. Methods A randomized split-mouth design clinical study was conducted after obtaining the ethical committee approval. A total of 50 patients, aged between 7 and 12 years, were randomized and enrolled in the study to perform a total of 200 sealant placements on all four caries-free and hypoplasia-free first permanent molars having deep fissures, which are susceptible to caries, were included in this study. The four permanent molars were divided into the following four groups: group A (control), B (Grandioseal, Voco, Germany), C (Smartseal & Loc, Detax Gmbh & Co, Germany), and D (Fuji triage capsule, GC, Belgium). The sealed molars were clinically evaluated at intervals of 6, 12, and 18 months to assess sealant retention, surface roughness, marginal coloration, and caries status through visual evaluation of the sealant by two evaluators. Results Concerning retention, there were statistically significant differences between the sealants in terms of the survival of partial and fully retained sealants as well as in the survival of caries-free teeth. Two resin-based (Smartseal & Loc) and glass-ionomer cement (Fuji triage) sealants showed significantly similar performances in permanent molars for up to 18 months. In terms of retention, one of the resin-based (Grandioseal) sealants performed better as compared to the others and showed better caries prevention in deep fissures. Conclusion It is concluded that both the sealants had comparable retention and caries-preventive effects in 7 to 12-year-old children and can be considered as suitable sealants for a period of at least 18 months in moderate caries risk patients.

Progression of Enamel Demineralisation Around Fissure Sealants: Optical Coherence Tomography Study.

To evaluate the progression of enamel demineralisation around fissure sealants using cross-polarisation optical coherence tomography (CP-OCT). Three fissure sealants; Fuji Triage (FJ, GC), Beautisealant (BT, Shofu) and Helioseal resin sealant (HL, Ivoclar Vivadent) were placed in cavities (3 × 0.5 × 1 mm) prepared in bovine enamel blocks (n = 5). After 7-day artificial saliva incubation, specimens were subjected to demineralisation for 4 weeks (pH 4.5). CP-OCT scans (Santec) were acquired for each specimen after 1, 2 and 4 weeks of demineralisation and lesions were quantitatively measured to analyse lesion progression. Repeated-measures ANOVA demonstrated that lesion size was statistically significantly affected by demineralisation period, fissure sealant type, and their interaction (P < 0.001). At 4 weeks, the highest mean value of lesion size was observed in HL group while FJ group showed the lowest. The rate of lesion progression was slower in FJ and statistically significantly different from BT (P < 0.05), which in turn was statistically significantly different than HL (P < 0.001). Fissure sealants that actively release ions are capable of improving the acid resistance of adjacent enamel. Beautisealant showed increased demineralisation inhibition compared to conventional resin sealant, but less than that provided by glass-ionomer sealant.

Adhesion of three types of fissure sealant in saliva-contaminated and noncontaminated conditions: an in vitro study.

To evaluate the proportion of microleakage (PM), shear bond strength (SBS), and the fissure sealant (FS) interface by scanning electron microscopy (SEM) in three kinds of FS when the enamel surfaces were contaminated with saliva. 198 sound third molar teeth were randomly divided into three pretreatment condition groups (n = 66): dry, saliva contamination removed by cotton pellet, or saliva removed by air-drying. A resin-based FS (Clinpro™), amorphous calcium phosphate-containing FS (Aegis®), or glass ionomer-based FS (Fuji Triage®) was applied on the treated enamel, and PM and SBS were assessed. Two specimens from each group were observed with SEM. p values < 0.05 was considered statistically significant. Glass ionomer-based FS showed the highest PM in all three surface conditions (p values < 0.05 were considered statistically significant). No significant difference in PM was observed between resin-based FS and amorphous calcium phosphate-containing FS (p > 0.05). Resin-based FS showed significantly greater SBS in all three surface conditions compared to glass ionomer-based FS. SEM observations showed that saliva contamination led to gaps at the enamel-sealant interface. Neither cotton pellet-drying nor air-drying effectively removed saliva from the contaminated enamel surface. Glass ionomer-based FS showed the highest PM and the lowest SBS in contaminated and noncontaminated conditions. The highest SBS was obtained with resin-based FS.

A Comparative Analysis of the Duration and Cost of Treatment Between Glass Ionomer and Resin Based Fissure Sealants among Children in Benin City, Nigeria

Background: Dental service utilization in children is reduced as a result of long treatment times and prohibitive cost of treatment. This may result in an increase in early childhood caries and subsequent premature tooth loss. Fissure sealants are a preventable method in the management of dental caries but the cost may be a barrier to early treatment.&#x0D; Aim: To compare the duration and cost of sealant treatment between glass ionomer and resin based fissure sealants among children in Benin City,Nigeria.&#x0D; Materials and Methods: All occlusal surfaces of the lower permanent first molars (2 teeth each in a total number of 50 children) were sealed andincluded in the study (n=100). A split-mouth design was used in which a light cure Bis-GMA resin-based sealant was compared with a glass-ionomersealant. They were then randomly placed in 50 matched contralateral pairs of permanent first molar teeth and a stop watch used to record the duration of placement. The cost of treatment was calculated by dividing the cost of the sealant kit with the total number of sealed occlusal surfaces. Statistical analysis was done using Statistical Package for Social Sciences version 21.0 with the chi square test for determination of variables. Probability values of p&lt;0.05 were considered statistically significant.&#x0D; Results: The duration of sealant treatment using resin based sealant ranged from 235 to 446 seconds (mean time 318.86 +55.54 secs); while theduration of sealant treatment using glass ionomer based sealant ranged from 238 to 360 seconds (a mean time 292.57 +33.56 secs); and this wasstatistically significant (P&lt;0.001). The cost of sealing a tooth surface using resin sealant (Clinpro®) was five hundred and seventy naira only. Similarly, the cost of sealing a tooth surface using glass ionomer based sealant (GC Fuji triage®) was eight hundred and forty naira only.&#x0D; Conclusion: Less chairside time is required for sealant treatment using glass ionomer than resin based sealant for fissure sealing procedures. The use of resin based fissure sealant is relatively cheaper when compared with glass ionomer based sealant&#x0D;

Influence of Laser and Ozone Pretreatment on the Shear Bond Strength of Fissure Sealants: An In Vitro Comparative Study

Aim: To evaluate the shear bond strength (SBS) of 3 fissure sealants used alone and with ozone and laser pretreatment. Materials and Methods: For the SBS test, the flattened enamel surfaces of 90 healthy third molars were randomly divided into nine groups ( n = 10 for each groups), based on different sealants (BeautiSealant, Fuji Triage, and Grandio Seal) and pretreatment conditions (no pretreatment, pretreatment with ozone, and pretreatment with neodymium-doped yttrium aluminum garnet [Nd:YAG laser]). Ozone was applied for 30 s in caries superficial mode, and Nd:YAG laser was applied for 60 s. After the pretreatment procedures, sealants were placed inside a mold on the enamel surface. SBS was measured with a universal testing machine. Data were analyzed using analysis of variance. Tukey’s multiple comparison tests were applied to determine the difference between the groups (α = 0.05). Results: The lowest SBS was observed in the Fuji triage group. Nd:YAG laser and ozone did not affect the SBS of BeautiSealant. However, significant differences were determined in the Fuji triage and Grandio Seal groups after pretreatment procedures ( P &lt; .05). Conclusion: Ozone and laser can be employed to disinfect fissures before BeautiSealant application.

The Effect of Simulated Field Storage Conditions on Dental Restorative Materials for Military Field Use.

Dental readiness, one critical component of medical readiness, is adversely impacted by dental emergencies. Many dental emergencies require restorative materials such as glass ionomers, resins, and zinc oxide eugenols to remedy them. The Authorized Dental Allowance List (ADAL) and Authorized Medical Allowance List (AMAL) contain the equipment and materials used by Navy dentists to treat Sailors and Marines. These supplies are subjected to harsh storage conditions on deployments. Much is known about how materials behave when stored at room temperature, but less is known about how their properties are affected after exposure to high temperatures and humidity. We subjected five dental restorative materials to storage in aggravated conditions, and then tested them to determine which products are more robust. Unopened packages of Fuji Triage, Fuji IX GP (both GC America Inc., Alsip, Illinois), TPH Spectra ST Low Viscosity, Intermediate Restorative Material (both Dentsply Sirona, York, Pennsylvania), and Herculite XRV (Kerr Corporation, Orange, California) were exposed to 0, 5, or 10days' storage at 30-60°C with 95% relative humidity. After storage in these aggravated conditions, we tested the compressive strength, hardness, elastic modulus, flexural strength, flexural modulus, sorption, and solubility of each material. The physical properties of all materials were affected by storage in aggravated conditions, though the properties of some materials degraded more than others. Both glass ionomers, Fuji Triage (P=0.0012) and Fuji IX GP (P=0.0031), and the composite Herculite XRV (P=0.0253) lost compressive strength after 5 or 10days in aggravated conditions. The hardness values for all materials were affected (P<0.05) by the aggravated conditions, though the elastic modulus of TPH Spectra was not affected (P>0.05). None of the materials lost flexural strength (P>0.05) or had changes in their flexural modulus (P>0.05). The water sorption behavior of Fuji Triage (P=0.0426) and Fuji IX GP (P=0.0201) changed after 10days of aggravated storage, and the solubility of all materials was altered by the harsh conditions. Some materials degrade more than others in aggravated conditions. Both resin composite materials were more resistant to high temperatures and humidity levels than the glass ionomers tested. These changes in physical characteristics should be considered when reviewing or optimizing the ADAL/AMAL for different projected operational environments.

Pit and fissure sealants penetration capacity and their correlation with fissure morphology.

Background and aimsPit and fissure sealant placement corresponds to an effective approach of the prevention of caries on occlusal surfaces. Fissure morphology and dental material characteristics are the key factors for sealant effectiveness. The aim of this in vitro study was to compare the penetration ability of two commercially available pit and fissure sealants.MethodsTwenty sound human premolars extracted for orthodontic purpose have been sealed according to manufacturer’s instructions as follows: Group I (n=10), light-cured unfilled resin-based sealant, Admira Seal® (Voco GmbH); Group II (n=10), resin modified glass ionomer sealant without varnish, GC Fuji Triage® (GC Corporation). The teeth have been sectioned buccal-lingually in the middle of the occlusal surface, and the sections were examined at 40× with an inverted microscope.ResultsPenetration of the sealants was found to be greater in U-type fissure pattern (91.69%) followed by V-type (75.42%), IK-type (71.24%) and then in I-type (63.98%). The depth of penetration of GC Fuji Triage® (82.85%) demonstrated to be superior to Admira Seal® (76.28%).ConclusionU fissure design was more common than other fissure patterns and showed significantly higher penetration for the two type of sealants evaluated. Resin modified glass ionomer sealant used in the present study perform comparably with the filled resin sealant.

Cell physiological effects of glass ionomer cements on fibroblast cells

The cytotoxicity of glass ionomer cements (GICs) was investigated using a novel, cost-effective, easy-to-perform and standardized test. GIC rings were made using in-house designed, custom-made moulds under sterile conditions; 10 with Fuji Equia and 10 with Fuji Triage capsules, placed in direct contact with primary human gingival fibroblasts (HGF) and immortalized human fibroblasts (HFF1). On day 1, 4, 14 and 21, an AlamarBlue® (resazurin) assay was completed towards determining the effects of the GICs on metabolic activities of the cells, whilst cell morphology was examined by light microscopy. The influence of the compounds released from the GIC rings on cell physiological effects (viability, proliferation and adhesion) during 24 h incubation was further investigated by impedimetry.Result trends obtained from this battery of techniques were complementary. At 100 v/v% concentration, the released compounds from Equia were strongly cytotoxic, while at lower concentration (0, 4, 20 v/v%) they were not cytotoxic. In contrast, Triage elicited only slightly transient cytotoxicity.The method proposed has been proved as being efficient, reliable and reproducible and may be useful in quick testing of the cytotoxicity of similar biomaterials by using an immortalized cell line.

Retention and remineralization effect of moisture tolerant resin-based sealant and glass ionomer sealant on non-cavitated pit and fissure caries: Randomized controlled clinical trial

Introduction/objectivesPit 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. MethodsThe 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. ResultsAfter 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). ConclusionsWithin 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.

Comparison of Glass Carbomer, Giomer, Glass Ionomer and Resin Fissure Sealants on Permanent Molar Teeth Fissure Sealants on Permanent Molar Teeth

Objectives: To compare the success of the newly developed glass carbomer-based fissure sealant to resin, glass ionomer, and giomer-based fissure sealants in permanent molar teeth according to the modified United States Public Health Service criteria. Methods: Glass carbomer-based fissure sealant GCP Glass Carbomer, glass ionomer-based fissure sealant Fuji Triage, giomer-based fissure sealant Beauti Sealant, and resin-based fissure sealant prevent seal were applied using invasive/non-invasive methods to extracted human molars. Specimens were randomly assigned into three groups based on the simulated aging procedure time. Results: According to the retention score results of Group 1, the invasive giomer material yielded the highest score in the Group. The retention score results of Group 2 showed that the invasive resin subgroup had the highest alpha-score. Furthermore, we found that the invasive GIS, non-invasive giomer, and invasive giomer subgroups had similar alpha-scores within Group 2. The glass carbomer and glass ionomer cement subgroups were unsuccessful in maintaining their edge integrity, edge coloring, surface roughness, and surface coloring. Conclusion: Thus, glass ionomer cements (GIC) and glass carbomer-based materials can be useful alternatives to residual monomers contained in resin-based fissure sealants. For patients who can be controlled regularly, glass carbomer fissure sealant can be applied using invasive methods.

Glass Ionomer Cement Sealant (GC Fuji TRIAGE®) in the Prevention of Post-eruptive Fractures in Molars Affected by Molar-Incisor Hipomineralisation: a Randomized Clinical Trial

Physical characteristics of two moisture tolerant fissure sealants immersed in commercial products with different pH range

Objective This study aimed to evaluate and compare between four physical variables (sorption, solubility, color change and fluoride release) for glass ionomer (GI) sealant against moisture tolerant resin sealant in solutions with different pH in different time intervals. Materials and methods Thirty discs were prepared from GI Fuji Triage and Embrace WetBond (EWB) resin sealant. Sorption, solubility and color change were measured after different time intervals (1 day, 1 week, and 1 month) of immersion of the specimens in different solution having different pH. In addition 10 disks were assessed for fluoride release of both sealants after being immersed in distilled water. Results EWB showed greater sorption in all media after 1 day and 1 week. GI sealant showed highest water sorption after 1 week and this sorption decreased again after 1 month. GI showed greater initial solubility in Pepsi and water after 1 day (P = 0.016). Pepsi showed higher solubility for EWB while no significant effect was found for GI with different media. The color change was greater for EWB when immersed in Pepsi and ginger. After 1-month storage, the color change was the highest specially for Pepsi for both sealants. Fluoride release was greater for GI compared to EWB. Conclusion Both sealants showed different physical performance depending on the type of immersion media and time period. This is expected to affect their mechanical properties and hence their clinical performance.

The heat risk during hardening of dental glass-ionomer cements using a light-curing

An use of a polymerization lamp to irradiate chemically hardened glass-ionomer materials may improve their properties and accelerate the setting time. However, an excessive increase in the temperature of a material poses a potential risk for the dental pulp. Maximum temperatures reported during irradiation of selected glass-ionomers have been determined in this paper for samples of sizes similar to those used in clinical practice. Three glass-ionomer materials used for filling dental cavities have been examined: GC Fuji VIII, GC Fuji Triage Pink, and GC Fuji Triage White. The LED Elipar lamp was used in the light-curing process. The temperature measurement on the outer surface of the samples was conducted with the use of the Thermovision®550 thermal imaging camera. The examined materials significantly differed in the maximum temperatures they reached, as well as the time they required to reach these temperatures. A statistically significant positive correlation of maximum temperature with the sample weight was observed for the GC Fuji Triage Pink material.

Bacterial adhesion on fissure sealants: Effects of exposure to acidic drink.

BackgroundAdherence of bacteria to teeth surface is considered an important step in the development of caries and the use of fissure sealants is crucial for the prevention of caries in occlusal surfaces of molars and premolars. The aim of this study was to investigate and compare the adherence of Streptococcus mutans to different fissure sealants, after acidic drink exposure.Material and MethodsThe tested materials were Fissurit, Fissurit FX, Grandio Seal, Fuji Triage, Constic. Bacterial suspension was deposited onto each material and the adhesion was evaluated trough the colony forming units (CFUs) determination with or without acidic drink exposure.ResultsThe tested materials showed different behaviors with significant differences. Bacterial adherence values of the untreated materials were very dissimilar: Fuji Triage and Constic materials showed the better results (P<0.05).ConclusionsSurface alteration after acidic drink exposure, changed the bacterial adhesion (except for Grandio Seal): Fissurit, Fissurit FX and Fuji Triage decreased their susceptibility to be colonized by S. mutans (P<0.05); on the contrary, Constic increased up to ~4 times the bacterial adhesiveness respected to the untreated control (P<0.05). Key words:Acidic drinks, bacterial adhesion, fissure sealants, Streptococcus mutans.
