Objective: The aim of this study was to determine the separate effects of dental sealants and fluoride varnish on dental caries in fissured and nonfissured surfaces of permanent first molars. Methods: A clinical trial was conducted with three groups of 6- to 8-year-old schoolchildren: a sealant group (n=100), in which Delton was applied to first molars; a varnish group (n=98), in which Duraphat was applied to first molars; and a control group (n=116), which had no intervention as part of the study. Absolute and percent caries reductions were compared at 24 months. Results: Compared to the controls, sealants resulted in a 68 percent and 87 percent reduction on fissured and nonfissured surfaces, respectively. The corresponding figures for varnish were 38 percent and 66 percent. Conclusion: Sealant and fluoride varnish are effective in preventing caries in both fissured and nonfissured surface.
Randomized Trial on Fluorides and Sealants for Fissure Caries Prevention
Journal of Dental Research, 2012
To investigate the effectiveness of topical fluorides in preventing fissure caries, we conducted a randomized controlled trial with parallel groups. In total, 501 children (1,539 molars, 3,078 sites), mean age 9.1 years, who had at least one sound permanent first molar with deep fissures or fissures with signs of early caries were recruited. They were randomly allocated among four groups:
Evaluation of fissure sealant applied to topical fluoride treated teeth
Fissure sealant is an important tool in the prevention of dental caries. This study evaluated the effect of treating the enamel with topical fluoride gel prior to acid etching on sealant retention clinically (Part I) and in vitro (Part II). In part I a split mouth design using contralateral first permanent molars was conducted. Seventy (35 pairs) molars were sealed. Fissure sealant was applied on one side of the mouth (control group) and the contralateral tooth received acidulated phosphate fluoride gel (test group) prior to acid etching. The sealant was evaluated after 6 and 12 months and scored as intact, partially lost or completely missing. In part II, the shear bond strength between sealant and buccal enamel of extracted permanent molars without or with topical fluoride treatment was evaluated. Results showed no statistically significant differences between the test and control groups either clinically or in vitro. It is concluded that topical fluoride application prior to acid etching does not have a deleterious effect on sealant retention. However, further investigations should be conducted using different types of fluoride before altering the traditional practices
Fluoride Varnishes for Preventing Occlusal Dental Caries: A Review
Dentistry Journal, 2021
Dental caries are most likely to occur on occlusal surfaces from the early eruptive stages of the tooth. In children, about 80% to 90% of dental caries are occlusal caries. Different preventive modalities are used to prevent occlusal caries. One of the methods used for occlusal caries prevention is fluoride varnish. A vast number of clinical trials have evaluated several types of sealant material and fluoride varnish to assess their ability to prevent occlusal caries in both primary and permanent dentition. The purpose of the current study was to provide an updated overview of the development, composition, mechanism of action, application, and safety of fluoride varnish, as well as its effect on occlusal caries prevention. This review of recently published studies on fluoride varnish and its effect on occlusal caries prevention shows that in children at moderate to high risk of caries, fluoride varnishes prevent occlusal caries. Both resin-based fissure sealants and fluoride varnish...
Fissure Seal or Fluoride Varnish? A Randomized Trial of Relative Effectiveness
Journal of Dental Research, 2017
Fissure sealant (FS) and fluoride varnish (FV) are effective in preventing dental caries when compared with a no-treatment control. However, the relative clinical effectiveness of these interventions is uncertain. The objective of the study was to compare the clinical effectiveness of FS and FV in preventing dental caries in first permanent molars (FPMs) in 6-to 7-y-olds. The study design was a randomized clinical trial, with 2 parallel arms. The setting was a targeted-population program that used mobile dental clinics in schools located within areas of high social and economic deprivation in South Wales. A total of 1,016 children were randomized 1:1 to receive either FS or FV. Resin-based FS was applied to caries-free FPMs and maintained at 6-mo intervals. FV was applied at baseline and at 6-mo intervals for 3 y. The main outcome measures were the proportion of children developing caries into dentine (D 4-6 MFT) on any 1 of up to 4 treated FPMs after 36 mo. At 36 mo, 835 (82%) children remained: 417 in the FS arm and 418 in the FV arm. A smaller proportion of children who received FV (n = 73, 17.5%) versus FS (n = 82, 19.6%) developed caries into dentine on at least 1 FPM (odds ratio [OR] = 0.84; 95% CI, 0.59 to 1.21; P = 0.35), a nonstatistically significant difference between FS and FV treatments. The results were similar when the number of newly decayed teeth (OR = 0.86; 95% CI, 0.60 to 1.22) and tooth surfaces (OR = 0.85; 95% CI, 0.59 to 1.21) were examined. In a community oral health program, semiannual application of FV resulted in caries prevention that was not significantly different from that obtained by applying and maintaining FS after 36 mo (EudraCT: 2010-023476-23; ISRCTN: ISRCTN17029222).
Inhibition of enamel mineral loss by fissure sealant: An in situ study
j o u r n a l o f d e n t i s t r y 4 1 (2 0 1 3) 4 2 – 5 0 a b s t r a c t Objectives: This study evaluated the effect of fluoride and non-fluoride sealants on hardness decrease (HD) and marginal adaptation (MA) on enamel substrates after cariogenic challenge. Methods: Occlusal enamel blocks, from human third molars, were randomly divided into six groups (n = 12), according to occlusal fissures condition (S – sound; C – caries-like lesion; CF – caries-like lesion + topical fluoride) and sealants (F – FluroShield; H – Helioseal Clear Chroma). Lesion depths were 79.3 AE 33.9 and 61.3 AE 23.9 for C and CF groups, respectively. Sealants were placed on occlusal surface and stored at 100% humidity (37 8C; 24 h/d). HD was measured by cross-sectional microhardness analysis at the sealant margin distances: À1 (under sealant), 0 (sealant margin), 1, 2 (outer sealant). Sealant MA was observed by polarized light microscopy and scored according to: 0 – failure (no sealant MA or total sealant loss); 1 – success (sealant MA present). MA and HD were analysed by ANOVA-R and mixed model analysis, respectively. Results: For HD (DS), F values (6900.5 AE 3686.6) were significantly lower than H values (8534.6 AE 5375.3) regardless of enamel substrates and sealant margin distances. Significant differences were observed among sealant margin distances: À1 (5934.0 AE 3282.6) < 0 (8701.5 AE 6175.7) = 1 (8473.2 AE 4299.4) = 2 (7761.5 AE 4035.1), regardless of sealant and sub-strate. MA was similar for all groups (p ! 0.05). Conclusion: MA was not affected by sealant type or substrate condition, whereas enamel HD was favourably impacted by fluoride in the sealant. In addition, sealants were more effective as a physical barrier than as its chemical potency in reducing enamel HD. Clinical significance: Sealing with a fluoride material is a recommended procedure to prevent caries of occlusal permanent molars in high-caries-risk patients, even though those exhibiting white spot lesions, since the enamel hardness decrease when fluoride sealant was used in vitro.
In vitro evaluation of fluoride products in the development of carious lesions in deciduous teeth
Brazilian Oral Research, 2009
The purpose of this study was to evaluate the effect of the application of fluoride products on the development of enamel caries in deciduous teeth. A total of 108 deciduous teeth were chosen for the study. Acid-resistant varnish was applied on the teeth, leaving only one area of 5 mm x 1 mm of dental enamel exposed. The teeth were allocated randomly to one of the following groups: 1) control-toothpaste without fluoride; 2) 1.23% fluoride gel; 3) Duraflur fluoride varnish; 4) Duraphat fluoride varnish; 5) Fluorniz fluoride varnish; 6) Fluorphat fluoride varnish; 7) varnish with Duofluorid; 8) 12% silver fluoride diamine (Cariestop); 9) children's fluoride toothpaste (500 ppm). The tested products were applied on the teeth according to the manufacturer's recommendations and the teeth were stored in a moist environment for 24 hours. Each group of teeth was then subjected to a pH cycling model for 14 days, after which the teeth were cut through the center for an analysis of the depth of the carious lesion by polarized light microscopy. Comparisons were made between the treatments and the control group. The mean lesion depth values were 318 µm ± 39 (control), 213 µm ± 27 (fluoride gel), 203 µm ± 34 (Duraflur), 133 µm ± 25 (Duraphat), 207 µm ± 27 (Fluorniz), 212 µm ± 27 (Fluorphat), 210 ± 28 (Duofluorid), 146 ± 31 (Cariestop) and 228 ± 24 (fluoride toothpaste). None of the products used here was able to completely prevent the formation of lesions. The highest cariostatic effect was achieved by fluoride varnish Duraphat and the lowest by the fluoride toothpaste. Descriptors: Fluorides; Dental caries; Deciduous tooth.

BACKGROUND Most of the detected increment in dental caries among children above the age of six years and adolescents is confined to occlusal surfaces of posterior permanent molars. Dental sealants and fluoride varnishes are much used to prevent caries. As the effectiveness of both interventions in controlling caries as compared with no intervention has been demonstrated previously, this review aimed to evaluate their relative effectiveness. It updates a review published originally in 2006 and updated in 2010 and in 2016. OBJECTIVES Our primary objective was to evaluate the relative effectiveness of dental sealants (i.e. fissure sealant) compared with fluoride varnishes, or fissure sealants plus fluoride varnishes compared with fluoride varnishes alone, for preventing dental caries in the occlusal surfaces of permanent teeth of children and adolescents. Our secondary objectives were to evaluate whether effectiveness is influenced by sealant material type and length of follow-up, docu...

Background/Aim: It is important to prevent caries on permanent first molars. Fissure sealants are very effective in protecting fissures from caries. The study aimed to determine the clinical success of fluoride-releasing fissure sealants in permanent first molars in the long term. Material and Methods: 64 children with 256 healthy erupted first permanent molars and followed for 5 years, comprised the study. Children who received a fluoride-releasing fissure sealant and came regularly to controls throughout 5 years were evaluated by retention rate and development of new caries and compared with a control group. Results: The complete retention rate of fluoride-releasing fissure sealants was 48.5% and 10.7 % of the sealed teeth had caries after 5 years. 25% of the teeth without fissure sealant were decayed after five years. There was no significant difference between the rate of retention of fissure sealants and the frequency of tooth brushing after 1 year. There was no significant dif...
Objective: Our study aims to evaluate the effect of mineralizing fluorine varnish on the progression of initial caries of enamel in temporary dentition by laser fluorescence. Material and Methods: Object of observation. 1 group-100 children aged 3, 4, 5 and 6 years treated with Clinpro ™ White Varnish with TCP (Tri-Calcium phosphate) (3M) – CV. Two groups-100 children aged 3, 4, 5 and 6 years without treatment with varnish CV. Location of the study-University Medical Dental Center Varna, Clinical Halls for Children's Dentistry, Faculty of Dental Medicine – Varna. Units of observation: Temporary teeth, Caries lesions at level d1 and d2. After processing the results and determination of the highlights was conducted by actual survey data processing package for mathematical and statistical analysis SPSS v 20.0. Results: The analysis of the results of temporary central incisors in six-year-old children showed a significant difference in the three study groups, the control group values being significantly higher than those in the treatment-treated group (t = 3.44, p<0.01) and those after treated with treatment with Clinpro White Varnish, TCP (t = 5.31, p<0.001). A significant difference showed the use of CV varnish, which showed improvement after treatment (t = 2.81, p<0.01). Results before and after treatment of lesions in the treated group also showed a significant difference, but better values were observed in temporary lateral incisors (t = 6.25, p<0.001 for temporary lateral incisors and t = 5.93, p<0.001 for temporary canines). The results in the study group before and after treatment also showed a significant difference in the provisional first and second molars (t = 7.53, p< 0.001 and t = 6.32, p< 0.001). Conclusion: 1. All reversible lesions may regress or stagnate by reducing the accumulated pathology above this diagnostic level. 2. After the first week, DIAGNOdent pen scores improved from less than three steps for d1b and d2 lesions and improved by two steps for d1a lesions. 3. Increased therapeutic efficacy of dental agents for non-invasive treatment is achieved by enhancing them with fluorides.
