Evaluation of the effect of enamel preparation on retention rate of fissure sealant
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 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 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 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 Following a single application of a chemically polymerized fissure sealant ( Concise Enamel Bond System ) 60 % of the sealants were present after 2 years of examination . The effectiveness of the treatment was highly significant and the caries reduction , irrespective of the sealant status , was found to be about 50 % . The caries reduction was 98 % in sealed pairs where the material was fully retained 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 BACKGROUND Long-term retention of pit and fissure sealants is essential for their success . The aim of this study was to compare the retention rates of sealants placed with acid-etching and air abrasion followed by acid etching . METHODS Sixteen subjects aged 16 and 17 years were included in the study . Using a half-mouth design , the authors performed fissure preparation with phosphoric acid gel on r and omly assigned maxillary and m and ibular permanent premolars and molars from one side of the mouth ( Group I ) and performed air abrasion followed by acid etching on the contralateral side of the mouth ( Group II ) . The authors applied sealant material on 162 teeth , and they evaluated the sealants as complete retention , partial loss or total loss at six , 12 and 24 months . RESULTS While fissure sealant retention rates were not significantly different for the two techniques at six months ( P = .97 ) , the retention rates for the teeth in Group II were significantly higher at 12 ( P = .025 ) and 24 months ( P = .002 ) . Molar retention rates were significantly less than those for premolars at each evaluation period ( P < .05 ) . CONCLUSION The sealant retention rates at 12 and 24 months were higher in Group II ( air abrasion followed by acid etching ) . CLINICAL IMPLICATION S As air abrasion followed by acid etching result ed in significantly higher sealant retention rates , this method could be a good choice for fissure preparation before sealant placement for long-term success 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 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 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 A 24-month clinical study was carried out to evaluate and compare the retention rate , marginal integrity and caries preventing effects of a polyacid-modified resin composite based fissure sealant , Dyract Seal , to that of a resin based fluoride fissure sealant , Delton FS+ .  Fifty-three patients ( 27 female and 26 male ) , 7 to 10 years old , were included in the study . At baseline , a total of 192 permanent first molars were sealed with either fissure sealant ( n=96 , each ) , using invasive technique . The sealed teeth were evaluated at post-operative 3 , 6 , 12 and 24 months with respect to evaluation parameters . The data were analyzed with the Chi-Square tests where alpha=0.05 . There were no statistically significant differences between fissure sealants as regards to retention and prevention of caries for all periods of the evaluation ( p>0.05 ) . However , regarding marginal integrity of the sealants , Delton FS+ gave significantly better results than Dyract Seal for the 3- , 6- and 12-month evaluations , respectively ( p<0.05 ) . In conclusion , the use of  Dyract Seal on permanent molars with invasive technique was found to be clinical ly comparable to Delton FS+ for the 24-month evaluation period Aim : This was to compare 3 different material s for fissure sealing ( FS ) after a clinical use during a 24 month period and to assess the use of flowable composite resins in combination with dentine adhesives as sealing material s. Study Design : There were 41 patients aged from 7–17 years , for whom 100 permanent molars were sealed with 3  different sealing material s. Methods : Group A , 33 teeth were sealed material Helioseal Clear Chroma ( Vivadent , Schaan , Liechtenstein ) ; Group B , 33 teeth were sealed with Teethmate F1 ( Kuraray , Kurashiki , Japan ) , and in Group C , 34 teeth were sealed with the flowable composite Tetric Flow ( Vivadent , Schaan , Liechtenstein ) . For the analysis of the degree of retention , the criteria used were : 0-complete retention , 1-loss of 1/3 of material , 2-loss of 2/3 of material , 3-complete loss of material . Clinical criteria for appearance of a new caries lesion included following values : Caries present ( + ) or caries absent ( − ) . Statistics : Chi-Square test was used for statistical analysis of retention rates between groups . Results : After the 24 month period , the highest retention rate of complete retention was established for the material Tetric Flow of 76.5 % , Helioseal Clear Croma 66.7 % , and Teethmate F1 60.6 % . The incidence of caries with Helioseal Clear Croma was 6.1 % , for Teethmate F1 3 % , with no statistically significant difference after the 24 months period ( p=0.656 ) . In the group of teeth sealed with Tetric Flow , there was not a single case of caries noted . Conclusions : The use of flowable composite resins as sealing material s is equal to other material s for fissure sealing The purpose of this study was to evaluate the retention of fissure sealants  , applied with 4 different combinations of isolation and preparation of occlusal surface . In 95 children aged 7 - 8 years , having all four first permanent molars fully erupted and caries free , a chemically initiated tinted fissure sealant was placed with the following 4 different methods in every child . 1 ) Tooth 16 : Cotton rolls isolation and cleaning of occlusal surface using a bristle brush and non-fluori date d paste . 2 ) Tooth 26 : Rubber dam isolation and mechanical preparation of pits and fissures using a round bur No. 0 in a slow h and -piece . 3 ) Tooth 36 : Rubber dam isolation and cleaning of occlusal surface using a bristle brush and non-fluori date d paste . 4 ) Tooth 46 : Isolation with cotton rolls and mechanical preparation of pits and fissures using a round bur No. 0 in a slow h and -piece .  Eighty children were available for re-examination 4 years later ( 320 teeth ) . The 4 methods of application showed the following success rates of full retention : 1 ) 81 % 2 ) 88 % 3 ) 91 % 4 ) 93 % . Although statistical analysis of the results revealed only marginal statistically significant difference among the four different methods of application ( p = 0.091 ) , there was statistical significant difference ( p = 0.031 ) between methods 1 and 4 . No differences were detected among the remaining methods . The present trial revealed best sealant retention using a combination of cotton rolls isolation and mechanical preparation of the occlusal surface . ( ABSTRACT TRUNCATED AT 250 WORDS AIM This was to evaluate the efficacy of pit and fissure sealant ( FS ) using two different application techniques for caries prevention assessed at five and ten years . METHODS The study was conducted using Delton(R ) pit and fissures sealant applied with either rubber dam ( RD )  ( Group A : 50 children , 200 first permanent molars , 120 second permanent molars ) or cotton wool rolls ( CR )  ( Group B : 50 children , 200 first permanent molars , 112 second permanent molars ) . At five and ten years FS were evaluated for retention , loss and incidence of occlusal and proximal carious lesions recorded . STATISTICS The data were analysed with the Chi- square test comparing the results obtained for first permanent molars and second permanent molars at five and ten years . RESULTS There was no statistical difference between results in the two groups ( p < or = 0.05 ) . The highest retention rate , 81.7 % , was found for second permanent molars sealed under RD at the five year assessment . The lowest , 64.3 % also for second molars sealed under CR humidity control at ten years . CONCLUSIONS Pit and fissure sealants are a valid preventive approach that can be applied with similar results with rubber dam or cotton rolls 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 .

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 The half-mouth technique was used to determine the treatment effect of an application of an ultraviolet-light-polymerized sealant . The side of the mouth to be treated with the sealant was r and omly selected . At the one-year examination , a statistically significant reduction in occlusal caries was found for teeth coated with the sealant . Practically no color change or marginal discoloration was evident and retention of the sealant was excellent Background : Prevention from caries is a principle in dentistry and fissure sealant therapy is being used as a preventive method success of sealants is directly depending on their retention . Aim : The Aim of the present study is to evaluate effects of enamel preparation on sealant retention . Setting s and Design : Clinical trial . Material s and Methods : About 57 children aged 6 - 8 year old took part in this study . 200 first molar teeth of these children has been r and omly separated into two groups : A case group ( Mechanically preparation of enamel ) and a control group ( conventional method , without preparation ) . After applying fissure sealants children were followed up 6 months later . Statistical Analysis Used : Mann- U- Whitney Test was used . Results : Complete retention after 6 month follow up was 86.7 % in case group and 82.8 % in control group . No significant difference was seen between the groups after 6 month follow up . ( P = 0.508 ) . Conclusion : Although statistical evaluation did n't show significant difference , but sealant retention was more after preparation technique
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 .
