“…Previous studies have reported similar results with pit and fissure sealants after using topical fluorides which have shown decreased enamel solubility, resulting in decreased bond strength. 19,20 Clinically, the etching of enamel creates microporos- ities within the enamel and reduces surface tension that allows the resin to penetrate and polymerize within the etched enamel rods. 21 Teeth with higher concentration of fluoride are more resistant to acid etching than normal teeth due to the formation of fluorapatite in the structure of the enamel surface, and topical fluoride application adversely affects etching treatment.…”

Objective: To evaluate the effect of prophylactic pastes containing active ingredients such as amorphous calcium phosphate (ACP), fluoride, or a combination of both on the enamel-bracket tensile bond strength. Materials and Methods: Human molars were randomly divided into four groups (N 5 40) according to the type of prophylactic pastes: control (no active ingredients), paste containing fluoride, paste containing ACP, and paste containing both fluoride and ACP. After prophylaxis, 20 brackets per group were bonded using an etch-and-rinse bonding technique (37% phosphoric acid and Ortho solo), and the other remaining 20 brackets were bonded using a self-etch bonding technique (Clearfil S 3 Bond). Samples were tested for tensile strength 24 hours after bonding using a universal testing machine. Data were analyzed using analysis of variance (ANOVA) and Student's t-test with significance level at .05. Results: The mean tensile bond strength varied between 3.043 (ACP) and 9.232 (control) MPa. The etch-and-rinse bonding technique was significantly affected by pastes containing active ingredients (P , .001). The self-etching system was not significantly affected by different pastes (P . .05). Conclusions: Cleaning enamel surfaces with prophylactic pastes that contain ACP and/or fluoride, prior to orthodontic bonding, resulted in a statistically significant decrease in the tensile bond strength of etch-and-rinse bonding technique.

“…Lightly filled epoxy resins were briefly used as fissure sealants, but their poor adhesion and instability, manifested by high-loss rates, prompted their withdrawal from clinical use. [23] Both types of materials have remained in use as endodontic sealers where they are largely protected from the oral environment by coronal restorations. However, coronal restorations may not always provide adequate protection.…”

Aim:The purpose of this study was to compare the in vitro micro-leakage resistance of adhesive resin materials to long-used zinc oxide-eugenol and epoxy resin sealers.Materials and Methods:Seven materials, five test (Real Seal, Real Seal XT, Panavia F 2.0, Infinity Syringeable, GCEM) and two controls (Tubliseal, AH Plus), were evaluated for micro-leakage resistance in a bovine incisor root model, with 12 roots per material. Teeth were root canal treated, stored in water, artificially aged by thermal-cycling, stained with silver nitrate, sectioned to yield eight measurement points per tooth (four coronal and four apical), giving 672 measurement points. Stain penetration was measured using digital positioners and a toolmakers microscope; then analyzed using descriptive statistics, two-way analysis of variance and multiple comparisons testing (P < 0.05).Results:All modern adhesive resinous materials leaked significantly less than long-used zinc oxide-eugenol and epoxy resin sealers (P < 0.05). Mean leakage values and their associated (standard deviations) in mm were: Infinity Syringeable 2.5 (1.5), Real Seal XT 3.2 (1.4), Real Seal 3.4 (1.6), Panavia F 2.0 3.8 (2.7), GCEM 4.2 (1.8), Tubli-seal 5.4 (2.8), AH Plus 6.3 (2.3). Overall, more leakage occurred apically than coronally (P < 0.0001). Many materials exhibited dimensional instability: Marked contraction, expansion, or lack of cohesion.Conclusion:A variety of adhesive resinous materials, endodontic sealers and crown cements, reduced micro-leakage in comparison to long and widely used zinc oxide- eugenol and epoxy sealers.

“…The effect on our results of the fluoride solution treatments used by some of the test subjects is not known. According to LEE, STOFFEY, ORLOWSKI, SWARTZ, OCUMPAUGH & NEVILLE (1972), topical fluoride treatments may be unfavorable for the retention of the sealant.…”

abstract— Findings 1.5 years after the application of the sealant revealed that among the 200 sealed permanent first molars, 2.5% of the sealants were lost or partly missing, while 95% of the sealants remained in good condition. During the test period, 7 of the 200 sealed permanent fissures had become carious, while 64 of the respective control fissures had decayed. The percentage effectiveness of the prevention by the present method was 85%. Four out of five molars that had lost the sealants became carious, but of the 190 molars having sealants in good condition, only three were diagnosed as carious. All teeth reported as contaminated with saliva at the sealing session had lost the material. No correlation could be found between the type of food eaten or oral hygiene habits of the subjects and the retention of the sealants.
