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 Background This article constitutes a partial up date of the original systematic review evidence by Yengopal et al. from 15 January 2008 ( published in the Journal of Oral Science in 2009 ) with primary focus on research quality in regard to bias risk in trials . Its aim is to up date the existing systematic review evidence from the English literature as to whether caries occurrence on pits and fissures of teeth sealed with either GIC or resin is the same . Methods In addition to the 12 trials included during the original systematic review , 5 new trials were identified during the data base search ( up to 26 August 2010 ) and 2 further trials were included from a h and search and reference check . Of these , 3 trials were excluded and 16 were accepted for data extraction and quality assessment . The quality of accepted trials was assessed , using up date d quality criteria , and the risk of bias was investigated in more depth than previously reported . In addition , the focus of quantitative synthesis was shifted to single data sets that were extracted from the accepted trials . Results Twenty-six dichotomous and 4 continuous data sets were extracted . Meta- analysis and cumulative meta- analysis were used in combining clinical ly homogenous data sets . The overall outcome of the computed data sets suggest no difference between the caries-preventive effects of GIC- and resin-based fissure sealants . Conclusions This overall outcome is in agreement with the conclusions of the original systematic review . Although the findings of the trials identified in this up date may be considered to be less affected by attrition- and publication bias , their risk of selection - and detection-/performance bias is high . Thus , verification of the currently available results requires further high quality r and omised control trials Abstract Fissure sealing using partially filled resins is an established caries preventive practice . Glass ionomer cement ( GIC ) sealants may offer additional advantages due to their ability to bond chemically to enamel and release fluoride . The aim of this study was to compare the caries preventive effect and retention of a GIC and a resin-based sealant . Ketac-fil ® was tested against a chemically cured resin-based material ( Delton ® ) using a split mouth design . Perth ( Western Australia ) schoolchildren ( n= 465 ) , mean age 7 yr±0.72 ( S.D. ) , received sealants  on the occlusal surfaces of sound homologous permanent first molar pairs .  Test ( GIC ) and control ( resin ) sealants were systematic ally allocated to left and right sides based on the child 's month of birth , and were placed by dental therapists . After 3.64±0.11 yr , 415 children were examined by different clinicians , and the clinical status of the teeth and the extent of sealant retention recorded . Sealants were deemed retained when at least 2/3 of the fissure pattern was still sealed . In 252 tooth pairs , neither sealant was retained to this extent . In 71 pairs , the GIC was not retained and the resin sealant retained . In 40 pairs the reverse occurred ( McNemar 's test , χ2= 8.66 , P < 0.005 ) . Net gain ( additional lesions prevented by the test agent per 100 treatments ) was 6.1%(95 % CI 3.3 % , 8.9 % ) . Effectiveness of the GIC was 80.6 % ( 95 % CI 59.6 % , 90.7 % ) . The relative risk of caries in test teeth was 0.19 ( 95 % CI 0.09 , 0.40 ) . The study suggests that complete retention of GIC sealant is not necessary for caries prevention in newly erupted permanent first molars The aim of this community-oriented study was to evaluate different methods to prevent fissure caries . The following products and measures were tested : 1 ) glass ionomer cement ( GIC ) applied by dentist ; 2 ) same material applied by short term ( 3 days ) trained personnel ( teachers ) ; 3 ) application of a 0.5 % HF solution three times ; 4 ) an established autopolymerized resin based sealant ( Delton ) . The study was performed in Bangkok , Thail and , a city in a developing country experiencing increasing caries prevalence . Children with at least three sound permanent molars from two age groups , 7 - 8 and 12 - 13-yr-olds respectively were chosen from very low to medium socioeconomic level families . 1264 children were systematic ally assigned to experiment or control groups based on school and DMFT . For the younger age group , the 2 yr mean DFS occlusal increment in the Control group was 0.66 surfaces . Significantly lower increments were observed in the GIC experimental group : 0.17 surfaces applied by the teachers and 0.32 applied by dentist , corresponding to 74 % and 52 % reductions , respectively . The mean increment in the HF group was 0.44 surfaces , a 33 % reduction in relation to the Control group . For the 12 - 13-yr-olds , the mean occlusal surface DF increment was 0.70 surfaces in the Control group . Almost no occlusal increment was found in the Delton group , 0.05 DFS , a 93 % reduction . In the GIC Dentist group , the DFS increment was 0.48 and in the Teacher group 0.56 , corresponding to 31 % and 20 % reduction , respectively . A slight and nonsignificant increase of caries in relation to the Control group was observed in the HF group . ( ABSTRACT TRUNCATED AT 250 WORDS 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 ) AIM The aim of this study was to compare the caries-preventive effect of two types of sealant modalities and to evaluate whether the caries-preventive effect is related to sealant retention . A hypothesis was tested in which a glass ionomer sealant , once applied to the occlusal surface , was able to protect the fissure from caries even if the sealant appeared lost at visual inspection . DESIGN A 3-year r and omized split-mouth trial evaluating two sealant modalities was performed at a public health centre in Finl and . A chemically curing glass ionomer cement ( GIC ) and light-curing resin-based ( RB ) sealant material were applied r and omly to the permanent second molars . Sealant application as a routine treatment procedure was carried out to 599 children in the age group of 12 - 16 years .  Caries rate of the sealed teeth and sealant retention with both material s were analysed by a modified McNemar 's test . The effectiveness , rate difference , and relative risk with both sealant material s were measured . RESULTS The difference in caries rate between the two modalities was highly significant . When compared to the GIC sealant method , the effectiveness of  RB sealant method was 74.1 % and the rate difference 3.2 % ( 95 % CI 1.44 % , 4.98 % ) . The relative risk for RB-sealed surfaces vs. GIC-sealed surfaces of having detectable dentin caries was 0.26 ( 95 % CI 0.12 , 0.57 ) . The retention rate of sealants was higher with RB than GIC ( P < 0.001 ) . The effectiveness of the retention rate for RB sealants was 94.8 % and the rate difference 87.2 % ( 95 % CI 83.86 % , 90.50 % ) . The relative risk during the 3-year study period of having a defective or lost RB sealant  was 0.052 ( 95 % CI 0.036 , 0.075 ) when compared to having a defective or lost GIC sealant . CONCLUSION It is concluded that in preventing dentin caries a RB sealant programme including resealing when necessary was more effective than a single application of GIC . The original hypothesis was thus falsified 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 This study 's purpose was to evaluate the caries-preventive effect of a glass ionomer cement ( GIC ) used as an occlusal sealant on recently erupted permanent first molars . METHODS A double-blind , r and omized , controlled , clinical trial was undertaken that included 36 5- to 8-year-olds ( and 92 permanent first molars ) who were r and omly allocated to the test group ( GIC ) or the control group ( auto-polymerized resin-based sealant [ RBS ] )  . The Mann-Whitney test was used to compare the number of new carious or filled occlusal surfaces in the 2 groups . RESULTS After 6 months , 1 occlusal surface in the test group and 2 occlusal surfaces in the control group showed carious lesions ( P=.15 ) . In the fifth year of follow-up , 2 occlusal surfaces in the test group and 7 occlusal surfaces in the control group were filled or carious ( P=.42 ) , and the mean number of sealed surfaces that became carious or filled was 0.2 ( 95 % confidence interval [CI]=0.02 - 0.70 ) for the GIC-sealed teeth and 0.6 ( 95 % CI=0.20 - 1.30 ) for the RBS-sealed teeth ( P=.30 ) . CONCLUSION High-viscosity glass ionomer cement can provide some level of protection against dental caries when used as a dental sealant in newly erupted permanent first molars 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 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
This systematic review with meta- analysis found no evidence that either material was superior to the other in the prevention of dental caries .
Thus , both material s appear equally suitable for clinical application as a fissure sealant material
The purpose of this quantitative systematic review was to appraise the evidence on the  caries-preventive effect of glass ionomer cement ( GIC ) in relation to  resin-based fissure sealants .
