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 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 hypotheses tested were : survival rate of fully and partially retained glass-carbomer sealants is higher than those of high-viscosity glass-ionomer , with and without energy supplied , and that of resin composite ; survival rate of fully and partially retained sealants of high-viscosity glass-ionomer with energy supplied is higher than those without energy supplied . The r and omized clinical trial covered 407 children , with a mean age of 8 years . The evaluation took place after 0.5 , 1 and 2 years . Survival of sealant material in occlusal and in smooth surfaces , using the traditional categorization ( fully and partially retained versus completely lost sealants ) and the modified categorization ( fully and more than 2/3 of the sealant retained versus completely lost sealants ) , were dependent variables . The Kaplan – Meier survival method was used . According to both categorizations of partially retained sealants , the survival of completely and partially retained resin composite sealants  in occlusal and in smooth tooth surfaces was statistically significantly higher , and those of glass-carbomer sealants lower , than those of sealants of the other three groups . There was no statistically significant difference in the survival rates of completely and partially retained high-viscosity glass-ionomer sealants with and without energy supplied in occlusal and in smooth surfaces . After 2 years , glass-carbomer sealant  retention was the poorest , adding energy to high-viscosity glass-ionomer sealant did not increase the retention rate and resin composite sealants were retained the longest . We suggest the use of the modified categorization of partially retained sealants in future studies . It seems not necessary to cure high-viscosity glass-ionomer sealants . The use of glass-carbomer sealants can not be recommended yet 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 In recent years , the interest in the use of glass-ionomer material s as fissure sealants has increased . The aim of this study was to compare the retention and caries-preventive effect of glass-ionomer ( Fuji III ) and resin-based light-cured ( Delton ) fissure sealants .  Three health center dentists applied the sealants to 166 children ; glass-ionomer sealants  on one side and resin-based sealants on the contralateral side of the mouth . After 2 yr , one pair of molar teeth in the mouths of 151 children was compared . Twenty-six percent of glass-ionomer and 82 % of resin-based sealants were totally present ( P < 0.001 ) . During the 2 yr , in both groups 4.6 % of the sealed surfaces became carious . The results show that the retention of glass-ionomer sealants  is markedly inferior to the resin-based sealants . In this study , however , no difference in caries increment on the sealed surfaces was observed . This may be due to the different mechanism of caries prevention for the sealant material s , or to the overall low caries activity of the participants The aim of this study was to compare the retention and caries preventive efficacy of glass ionomer ( Fuji III ; GIC ) and light-cured resin-based ( Delton ; LCR ) fissure sealants .  One hundred and sixty-six 5 - 14-year-old schoolchildren received sealants on their newly erupted first or second molars ; a split mouth design was used . Previously reported 2-year results showed low retention rates for GIC sealants , but no difference in the caries increment between the groups . The same persons were invited to a dental check-up 6.1 to 7.8 ( mean 7.1 ) years after the application of sealants ;  111 persons ( 66.8 % of the original group ) participated in the study . The retention of sealants , and the caries status of occlusal surfaces and adjacent proximal surfaces was recorded . On the sealed occlusal surfaces , 10 % of GIC and 45 % of LCR sealants were totally and 9 % of GIC and 20 % of LCR sealants partially present . Twenty-three ( 23.5 % ) of the occlusal surfaces sealed with GIC and 16 ( 16.5 % ) of those sealed with LCR were carious or filled . Compared to LCR sealants , the effectiveness of GIC sealants  was -44 % ( 95 % CI -71 % , -16 % ) and net gain -7 % ( 95 % CI -18 % , 4 % ) . The relative risk of caries occurring was 1.44 ( 95 % CI 0.96 , 2.14 ) 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 OBJECTIVE To compare the retention and the caries preventive effect of a glass-ionomer developed for fissure sealing ( Fuji III ) and a chemically polymerized resin-based fissure sealant ( Delton ) . DESIGN A split mouth r and omized design using contralateral teeth . SETTING WHO Regional Demonstration , Training and Research Center for Oral Health , Damascus , Syrian Arab Republic . SAMPLE AND METHODS 179 children , 7 years old at the start of the study , were recruited from schools close to the Center . Only children with at least one pair of permanent first molars that were caries free or only had incipient lesions were included in the study . Follow-up examinations for sealant retention were done after 6 months , 1 year , 2 years and 3 years . The number of children available for reexamination was 129 ( after 6 months ) ; 121 ( after 1 year ) ; 115 ( after 2 years ) and 116 ( after 3 years ) . Four dental hygienists were trained in the sealant procedures and did approximately one fourth of the sealants each . RESULTS After 3 years the  glass-ionomer sealant was completely lost in almost 90 % of the teeth compared to less than 10 % of the resin sealed teeth . After 3 years the relative risk of a tooth sealed with glass-ionomer over that of a tooth sealed with resin was 3.38 ( 95 % CL : 1.98 ; 5.79 ) . This finding was consistent over type of tooth . CONCLUSIONS The glass-ionomer sealant tested in the present study had poorer retention and less caries protective effect than the resin-based sealant used PURPOSE To test the hypotheses : 1 ) cumulative survival rates of fully and partially retained high-viscosity glass-ionomer ( HVGIC ) ART sealants with heat application and glass-carbomer sealants on occlusal and free-smooth surfaces are both higher than that of resin sealants ; 2 ) cumulative survival rate of fully and partially retained high-viscosity glass-ionomer ART sealant with heat application on occlusal and free-smooth surfaces is higher than that of comparable ART sealants without heat application . MATERIAL S AND METHODS The block-r and omised clinical trial covered 405 eight-year-old children . The HVGIC was Ketac Molar Easymix , the glass carbomer was GlassCarbomer and the resin sealant was Clinpro . Retention rates of sealants on occlusal and free-smooth surfaces using conventional and modified categorisation ( fully and partially retained sealants vs those completely lost [ at least one-third of surface re-exposed ] ) were the dependent variables . The Kaplan-Meier survival method was used . RESULTS The cumulative survival rate of completely and partially retained resin sealants  on occlusal ( 81.2 % ) and free-smooth ( 81 % ) surfaces after 4 years was statistically significantly higher , and that of glass-carbomer sealants ( 10.8 % and 21.1 % , respectively ) was statistically significantly lower than those of the other sealant groups . There was no statistically significant difference in survival rates of completely and partially retained high-viscosity glass-ionomer ART sealants with ( 56 % for both surfaces ) or without heat application ( 56 % ) on occlusal and free-smooth surfaces ( 55.7 % and 59.1 % , respectively ) . CONCLUSIONS Resin sealants had the highest and glass-carbomer sealants the lowest retention rate after 4 years . Application of heat to high-viscosity glass-ionomer ART sealants did not result in a significantly higher sealant retention rate . Use of the modified categorisation for determining sealant retention is advocated OBJECTIVES The null-hypothesis tested was ; there is no difference in effectiveness between a new low-viscosity glass ionomer and a resin-based glutaraldehyde containing primer in treating hypersensitive teeth after 2 years . METHODS Using a split-mouth design , hypersensitive teeth in 14 adult patients were r and omly assigned to 2 treatment groups . Hypersensitive tooth surfaces were covered with a low-viscosity glass ionomer ( Fuji VII ) and a resin-based glutaraldehyde containing primer ( Gluma Desensitizer ) . The discomfort interval scale ( DIS ) ranging from 0 to 4 was used to test the level of hypersensitivity before and after treatment , and at 3 months using compressed air blown for 2 s , and at 1 and 25.2 months using a telephone interview . Differences between and within the treatment groups were tested using the sign rank test . RESULTS Evaluations in the gluma group were discontinued after 3 months . The mean DIS score for hypersensitive teeth in the glass ionomer group was statistically significantly lower than that in the gluma group , immediately after application ( p=0.0005 ) , after 1 month ( p=0.02 ) and after 3 months ( p=0.003 ) . After 3 months , 11/14 of the hypersensitive teeth in the glass ionomer group and 2/14 in the gluma group were free of sensitivity . The mean DIS score for hypersensitive teeth in the glass ionomer group remained low after 19.2 months ( 0.25 : S.E.=0.13 ) and 25.2 months ( 0.22 : S.E.=0.15 ) . CONCLUSIONS The null-hypothesis was rejected . The low-viscosity glass ionomer ( Fuji VII ) is more effective in treating hypersensitive teeth than Gluma Desensitizer after 3 months . The positive treatment effect of the glass ionomer continued until 25.2 months The aims of the present study were to evaluate the retention and caries-preventive effect of a single application of a light-cured resin-reinforced glass-ionomer cement ( Vitrebond ) in pits and fissures of newly erupted permanent first and second molars , when compared with a single application of a resin-based sealant ( Concise White Sealant ) during a 3-year period . The study group comprised 73 pairs of contralateral newly erupted permanent first and second molars ( 136 fissure sites ) in 53 children ( 29 girls , 24 boys ) . A split-mouth experimental design was used in which the two sealants were r and omly allocated to one of the teeth within each pair . Acid etching was not used before application of the glass-ionomer cement . The sealed teeth were checked for retention and caries after 1 , 6 , 12 , 24 and 36 months . The resin-based sealant was almost totally retained after 3 years ( 97 % ) and there was no caries in these teeth . The glass-ionomer cement was increasingly lost and could be observed in only 9 % of the sealed sites after 3 years . Carious lesions developed in 10 ( 7.4 % ) sites ( nine teeth , seven children ) . It was concluded that the resin-based sealant is superior to the glass-ionomer cement in preventing caries , and that the superior retention of the resin probably is an important factor for this PURPOSE To evaluate the retention and caries-preventive effectiveness of two ionomeric material s ( conventional and resin-modified ) , used as fissure sealants . MATERIAL S AND METHODS 100 children ( 6 - 8 years old ) with a total of 400 permanent first molars received  200 conventional glass-ionomer ( Ketac Bond ) and 200 resin-modified glass-ionomer ( Vitremer ) sealants .  Additionally , 108 children constituted the control group ( 432 teeth ) . Two dentists assisted by dental hygienists performed the sealant application . Clinical evaluations were carried out 6 , 12 , 24 , and 36 months after the sealant application by two other dentists , not carrying out clinical procedures , previously calibrated ( Kappa > 0.75 ) . RESULTS Total retention rates of 26 % , 12 % , 3 % , and 4 % for Ketac Bond and 61 % , 31 % , 14 % , and 13 % for Vitremer , being 6 , 12 , 24 , and 36 months after clinical evaluation , respectively . The differences between the two material s were statistically significant . The experimental groups showed a caries incidence of 93 % , 78 % , 49 % , and 56 % lower than the control group ( P < 0.01 ) for the four evaluation periods , respectively . In conclusion , the retention rates of ionomeric material s were low . Nevertheless , these material s showed a cariostatic effect , supported by statistically lower caries incidence in experimental groups compared to control group . Presence of active incipient caries was statistically associated with caries incidence in the first molars after 36 months , in relation to either experimental or control group 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 PURPOSE The aim of this work is to study and compare the retention rate , caries-preventing and antibacterial effects of resin-modified glass ionomer and flowable composite in comparison to conventional fissure sealant . METHODS Forty-five children aged 7 - 10 years with newly erupted lower first permanent molars were r and omly divided into three equal treatment groups . Group I : sealed by a conventional resin sealant ; Group II : sealed by resin modified glass ionomer ( RMGI ) ; and Group III : sealed by flowable composite .  Retention and caries status of the sealed teeth were recorded after 1 month , 6 months , year and 2 years . In addition , Streptococcus mutans counts were assessed at baseline , 1 day , 1 month , 6 months , 1 year and 2 years after sealant application . Data were analyzed by Fisher exact , chi-square and ANOVA tests . RESULTS Group III and Group I showed significantly higher retention rates than Group II fissure sealant ( p<0.05 ) . There were no differences of the caries-preventive effects between the tested sealant material s throughout the duration of the study . Streptococcus mutans counts were significantly lower in group II compared to group I or group III up to 6 months of the study ( p<0.05 ) . After 1 year of the study the differences of Streptococcus mutans counts were not significant ( p>0.05 ) . CONCLUSION This study indicated a lower retention of RMGI compared to flowable composite and resin sealant without significant difference in caries prevention or long-term bacterial inhibition While a one-year report had been previously published , this study was undertaken to evaluate the clinical performance and appearance of a resin-modified glass ionomer and a resin composite over two years . Thirty-seven pairs of restorations of FujI II LC and Z 250/Single Bond were placed in caries-free cervical erosion/abfraction lesions without tooth preparation . Restorations were clinical ly evaluated at baseline , 6 , 12 , 18 and 24 months using modified Ryge/USPHS criteria . No statistically significant difference ( p = 0.13 ) was observed in the overall performance of the material s. Retention was 96 % for the resin-modified glass ionomer and 81 % for the resin composite , with no additional restorations of either material lost after one year . As previously reported , retention of the Z 250 restorations at six months was below the minimum specified in the ADA Acceptance Program for Dentin and Enamel Adhesives . The resin composite restorations generally had a better appearance , with a 100 % alpha rating in color match , versus 85 % for the resin-modified glass ionomer 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 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-r and omized 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
This study confirms the likelihood that remnants of high-viscosity glass-ionomer sealant material are retained and block the deeper parts of pits and fissures even after the sealant appears to have disappeared clinical ly , exercising their carious lesion preventive effect
OBJECTIVES Resin composite sealants are retained longer than low-viscosity glass-ionomer sealants .
Nevertheless , a systematic review showed that there is no evidence that resin composite sealants are superior to low-viscosity glass-ionomers in preventing dentine carious lesion development .
This case study aim ed to investigate reasons for this .
