OBJECTIVES The aim of this clinical study was to evaluate the retention rate and caries-prevention effect of a flowable composite compared to a conventional resin-based sealant in a young population over a 24-month period . METHODS Thirty-four patients , ranging in age from 16 to 22 years , diagnosed with at least 2 non-cavitated pit- and -fissure caries in the first and second molars were selected for this r and omized split-mouth design trial . A total of 220 sealants , were placed in 117 upper molars and 103 lower molars . The teeth were sealed with a flowable resin composite ( Tetric Evo Flow ) or a sealant material ( Helioseal F ) . Each restoration was independently evaluated in terms of retention and the presence of caries at baseline and at 1 , 6 , 12 , and 24 months . Data were analyzed using non-parametric Mann-Whitney U and Friedman 1-way ANOVA tests at p<0.05 . RESULTS Tetric Evo Flow showed complete retention with 100 % , 95.5 % , 93.8 % , and 88.5 % at 1 , 6 , 12 , and 24-month evaluations , respectively , while Helioseal F retention rates were 98.1 % , 95.5 % , 94.8 % , and 85.4 % , respectively , for the same evaluation periods . At the 24-month recall , 4 ( 4.2 % ) total losses were observed in subjects treated with Tetric Evo Flow and 2 total losses ( 2.1 % ) for Helioseal F , respectively . No significant differences were observed between the material s in retention rates or caries incidence for each evaluation period ( p>0.05 ) . CONCLUSION Placement of flowable composite as fissure sealants in the younger population seems to be as effective as conventional fluoride containing fissure sealants for the prevention of fissure caries . CLINICAL RELEVANCE The use of a flowable composite as a fissure sealant material , in conjunction with a total-etch , single bottle adhesive , yielded better retention than did the conventional fluoride containing resin-based fissure sealant over a 24-month period in young patients PURPOSE Pit and fissure sealants reduce occlusal caries when proper patient selection and application techniques are followed . To increase retention rate of sealants over time , good adaptation and deep sealant penetration are important . Studies remain inconclusive , however , as to determining if the bur preparation of pits and fissures would increase the adaptation and penetration thus improving sealant retention . The aim of this study was to assess if tooth preparation prior to sealant application improves sealant retention . METHODS In this prospect i ve cohort study , 43 children and adolescents from 4 Hutterites colonies were , for 3 years , bussed to the University of Manitoba pediatric dental clinic , Winnipeg , Manitoba , Canada , for comprehensive dental care including  sealant placement  using st and ard procedures . These came from a community with homogeneous social economical status , dietary habits , fluoride intake , and lifestyles . The decision of tooth preparation prior to sealant application was made ad hoc . Of 122 treated permanent posterior teeth , 54 had been treated as preventive resin restorations ( PRRs , type A or B ) and 68 were nonprepared sealants .  RESULTS After 1 year , teeth prepared ( type B PRRs ) and restored with flowable composite resins had significantly ( P<.01 ) lower retention rates ( 27 % vs 63 % ) than did teeth with nonprepared sealants or typeA PRRs . Teeth prepared ( type B PRRs ) were also significantly ( P<.001 ) more likely to have caries on follow-up examination ( 50 % vs 11 % ) than were teeth with nonprepared sealants or type A PRRs . CONCLUSIONS These results suggest that preventive resin type B restorations restored with flowable composites are not helpful in terms of retention or caries reduction UNLABELLED This clinical trial evaluated the retention rate of a flowable restorative system ( Bond 1 + Flow-It ! ) used as a pit- and -fissure sealant compared with a conventional filled resin sealant ( Fluroshield ) over a 1-year period . METHOD Using a half-mouth design , 160  sealants  ( 80 in primary and 80 in permanent teeth ) were placed on sound first/second primary molars and first permanent molars of 40 children aged between 4 and 7 years . For both primary and permanent dentitions , half the teeth ( n = 40 ) were sealed with Fluroshield and half ( n = 40 ) with Bond 1 + Flow-It ! Teeth were evaluated at baseline , 6- and 12-month intervals . RESULTS For both material s , there was no total loss of sealants placed on either the primary or permanent molars over 1 year . From Fluroshield sealants placed on primary teeth , 33 were completely intact after 6 months and 31 after 1 year . From those placed on permanent molars , no loss of material was observed after 6 months , while partial loss was noticed on 5 % of teeth at 1-year recall . For Flow-It ! resin applied on primary molars , partial loss of material was observed in only 1 sealant after 6 months and in 2 sealants after 1 year . On permanent teeth , 100 % retention rate was observed over a 1-year follow up . There was a statistically significant difference ( P < 0.01 ) between the sealing material s on primary but not permanent teeth , and , overall , Flow-It ! sealants presented a higher retention rate at both 6-month and 1-year evaluations . Significant differences ( P < 0.01 ) between baseline and the other evaluation periods were also observed . CONCLUSION It may be concluded that the flowable restorative system yielded optimal retention on both primary and permanent molars . Its retention rate was significantly higher than that of the conventional pit- and -fissure sealant on primary teeth 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 r and omized 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 AIM : To evaluate retention and caries prevention of a glass-ionomer cement ( GIC ) and a resin-based fissure sealant placed by fifth-year undergraduate dental students . METHODS : The study was conducted according to a split-mouth , r and omised clinical trial . Children with at least one pair of caries-free permanent first molars with deep pits and fissures were included in the study . The children were selected from a population that had a high risk for dental caries .  Sealant material s were applied by fifth-year undergraduate dental students on 346  fissures of the first permanent molars in 173 children . The ages of the children ranged from 7–15 years ( mean 9.4 ) . Two research ers at the clinics supervised all of the procedures . Intra-examiner reproducibility and inter-examiner reproducibility were 0.90 and 0.86 , respectively , for the clinical assessment of sealant retention and caries evaluation . RESULTS :  GIC sealants were completely lost in 31.9 % and resin-based sealants in 16.6 % ( p<0.05 ) . The total retention rates of GIC sealants and resin-based sealants were 13.8 % and 20.8 % , respectively . After 24 months , the caries increment was 3.4 % for GIC sealants and 4.8 % for resin-based sealants ( p>0.05 ) . CONCLUSIONS : The retention of GIC sealants was markedly inferior to the retention of resin-based sealants ; however , GIC when used as a pit and fissure sealant was slightly more effective in preventing occlusal caries To evaluate the retention and caries experience effects of three different material s used as fissure sealants after 24 months of clinical application : a resin-modified glass ionomer cement ( A ) , a flowable resin composite ( B ) and a compomer ( C ) .  One hundred and seventeen ( 117 ) teeth were sealed with material A , 119 teeth with material B and 120 teeth with material C. Children were r and omly assigned . Each one received only one of the material s studied .  Plaque index , dmft score and socioeconomic level were scored at baseline . The clinical exams were conducted 6 , 12 and 24 months after application of the sealant . Statistical analysis ( Kruskal-Wallis ) revealed that there were statistically significant differences between the retention rates of groups A and B and between groups B and C after 2 years , with material B showing better results . After 2 years , 3.1 % of the teeth of group A , 4.3 % of group B and 6.7 % of group C were Carious+Filled . There was no evidence of association between caries presence after 2 years and plaque index , dmft score and socioeconomic level . These results suggest that flowable resin composite had a satisfactory retention after this period of evaluation and all three material s were effective on occlusal caries prevention 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 r and omized 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 Sealing occlusal pits and fissures with resin-based sealants is a proven method of preventing occlusal caries . Retention of the sealant is very essential for its efficiency . This study evaluated the retention of glass ionomer used as a fissure sealant when compared to a self-cure resin-based sealant .  One hundred and seven children between the ages of 6 - 9 years , with all four newly erupted permanent first molars were selected . Two permanent first molars on one side of the mouth were sealed with Delton , a resin-based sealant , and the contralateral two permanent first molars were sealed with Fuji VII glass ionomer cement .  Evaluation of sealant retention was performed at regular intervals over 12 months , using Simonsen 's criteria . At the end of the study period , the retention of the resin sealant  was seen to be superior to that of the glass ionomer sealant BACKGROUND This article presents evidence -based clinical recommendations for the use of pit- and -fissure sealants on the occlusal surfaces of primary and permanent molars in children and adolescents . A guideline panel convened by the American Dental Association ( ADA ) Council on Scientific Affairs and the American Academy of Pediatric Dentistry conducted a systematic review and formulated recommendations to address clinical questions in relation to the efficacy , retention , and potential side effects of sealants to prevent dental caries ; their efficacy compared with fluoride varnishes ; and a head-to-head comparison of the different types of sealant material used to prevent caries on pits- and -fissures of occlusal surfaces . TYPES OF STUDIES REVIEW ED This is an up date of the ADA 2008 recommendations on the use of pit- and -fissure sealants on the occlusal surfaces of primary and permanent molars . The authors conducted a systematic search in MEDLINE , Embase , Cochrane Central Register of Controlled Trials , and other sources to identify r and omized controlled trials reporting on the effect of sealants ( available on the U.S. market ) when applied to the occlusal surfaces of primary and permanent molars . The authors used the Grading of Recommendations Assessment , Development , and Evaluation approach to assess the quality of the evidence and to move from the evidence to the decisions . RESULTS The guideline panel formulated 3 main recommendations . They concluded that sealants are effective in preventing and arresting pit- and -fissure occlusal carious lesions of primary and permanent molars in children and adolescents compared with the nonuse of sealants or use of fluoride varnishes . They also concluded that sealants could minimize the progression of non-cavitated occlusal carious lesions ( also referred to as initial lesions ) that receive a sealant . Finally , based on the available limited evidence , the panel was unable to provide specific recommendations on the relative merits of 1 type of sealant material over the others . Conclusions and practical implication s : These recommendations are design ed to inform practitioners during the clinical decision-making process in relation to the prevention of occlusal carious lesions in children and adolescents . Clinicians are encouraged to discuss the information in this guideline with patients or the parents of patients .

The authors recommend that clinicians re-orient their efforts toward increasing the use of sealants on the occlusal surfaces of primary and permanent molars in children and adolescents Objective : The purpose of this clinical study was to compare the retention rates of two flowable restorative systems ( Admira Flow and Gr and io Flow ) with that of a conventional resin-based sealant ( Fissurit F ) . Material s and Methods : The study was planned as a clinical trial with a split-mouth design . A total of 122 sealants ( 38 Admira Flow , 41 Gr and io Flow , 43 Fissurit F ) were r and omly applied to completely erupted permanent molars in 35 patients aged 9–20 years and followed up for 24 months . Data were analyzed using Pearson ’s χ2 and multiple comparison tests . Results : At the end of the follow-up period , Fissurit F had higher retention rates ( 81.0 % ) than both Admira Flow ( 60.5 % ) and Gr and io Flow ( 57.1 % ) , with p < 0.05 . However , there was no significant difference in caries development among groups ( p > 0.05 ) . Conclusion : The two flowable composite resin material s used as fissure sealant were less retentive than the conventional resin sealant The aim of the present trial was to ( 1 ) compare the caries-preventive effect of glass ionomer sealants , placed according to the atraumatic restorative treatment ( ART ) procedure , with composite resin sealants over time and ( 2 ) investigate the caries-preventive effect after complete disappearance of sealant material . Forty-six boys and 57 girls , mean age 7.8 years , were r and omly divided into two treatment groups in a parallel-group study design . A light-polymerized composite resin sealant material and a high-viscosity glass ionomer were each placed in 180 fully erupted first molars in their respective treatment groups . Evaluation took place annually for 5 years by calibrated examiners . After 5 years , 86 % composite resin and 88 % glass ionomer sealants did not survive . Three categories of re-exposure periods for caries development in pits and fissures after complete loss of sealants were distinguished : 0–1 , 1–2 and 2–3 years . In the 2- to 3-year group , 13 and 3 % of pits and fissures previously sealed with composite resin and glass ionomer , respectively , were diagnosed as having developed a dentine lesion . The relative risks ( 95 % CI ) of dentine lesion development in surfaces sealed with glass ionomer compared to those sealed with composite resin after 3 , 4 and 5 years were 0.22 ( 0.06–0.82 ) , 0.32 ( 0.14–0.73 ) and 0.28 ( 0.13–0.61 ) , respectively . The relative risks of dentine lesion development in pits and fissures previously sealed with glass ionomer compared with composite resin over re-exposure periods of 1–2 and 2–3 years were 0.26 ( 0.14–0.48 ) and 0.25 ( 0.09–0.68 ) , respectively . We conclude that the caries-preventive effect of high-viscosity glass ionomer sealants , placed using the ART procedure , was between 3.1 and 4.5 times higher than that of composite resin sealants after 3–5 years . Furthermore , high-viscosity ( ART ) glass ionomer sealants appear to have a four times higher chance of preventing caries development in re-exposed pits and fissures of occlusal surfaces in first molars than light-cured composite resin sealant material over a 1- to 3-year period . A well- design ed clinical trial using different types of oral health personnel should be implemented to confirm these initial results The purpose of the study was to evaluate whether the clinical effectiveness of pit and fissure sealant  was increased ( as demonstrated by an increased retention rate ) when a bonding agent was used prior to the placement of the sealant . Two pit and fissure sealants , Concise Light Cured White Sealant and Prisma Shield Light Cured Sealant , were placed in vivo with and without the use of the bonding agents , Scotchbond 2 and Prisma Universal Bond . After 2 years , 55 % of the sample was available for recall . The retention rates for the sealants were 77 % for Concise with Scotchbond 2 , 84 % for Concise with no bonding agent , 77 % for Prisma Shield with Universal Bond , and 77 % for Prisma Shield with no bonding agent . Results of this study indicated that the use of a bonding agent prior to the application of a pit and fissure sealant does not increase the retention rate PURPOSE To compare the h and ling and 6-month clinical performance of an experimental resin-modified glass ionomer cement ( K-512 = Fuji III LC ) with that of a light-cured resin-based sealant ( Delton Opaque ) when used as a pit and fissure sealant in 15 - 27 year old subjects . MATERIAL S AND METHODS Seventeen patients with 65 cement and 55 resin-based sealants  were recalled after 6 months for clinical examination and color photographs . RESULTS Sealant retention failures requiring retreatment were 74 % for the glass ionomer cement sealant and 11 % for the resin-based sealant , with one instance of fissure caries being found for each material . The resin-modified glass ionomer cement sealant showed a slight darkening from its initial placement , and was also more difficult to h and le than the resin-based sealant
Conclusion It seems that the use of flowable composite as a fissure sealing material can slightly increase the retention rate of sealants compared with conventional resin-based sealants
Objectives The aim of this systematic review and meta- analysis was to evaluate fissure sealant retention in clinical studies in which investigators used flowable composites as pit and fissure sealants compared with conventional resin-based pit and fissure sealants .
