“…no material is able to produce a 100% decrease in dentin permeability. Supposedly, if a material seals the interface perfectly, the passage of¯uid should drop to zero [5], but this occurred in none of our experiments. Our results show a wide range of permeability decreasing rates.…”

“…Consequently, we have adopted a quantitative method to assess microleakage, based on various studies by Pashley et al [1,12,16,22] and by other authors [5,7,8]. The results obtained can be compared with the results of other studies.…”

“…Bacterial penetration could lead to pulpal irritation [1±3]. In addition, a non-physiological sealing would permit greater movement of the dentin¯uid in the tubules that could result in dentin hypersensitivity if the hydrodynamic stimuli reach a suf®cient threshold [1,2,4,5].…”

“…Different authors [1,3,4,5,11±15] have disagreed on this point. For some researchers [1,3,5,12,13,15] it is clear that dentin permeability (i.e. the sealing ability) is inversely related to the magnitude of bond strengths.…”

Objectives: (1) Test the sealing capacity and tensile strength of various adhesive systems: Scotch Bond 1 (Single Bond in USA)(SB1) 1 Z100, Syntac Sprint (SYN) 1 Tetric Ceram, Prime and Bond 2.1 (PB21) 1 TPH Spectrum, F2000 (Adhesive 1 Compomer) (F2000) and Optibond Solo (OPT) 1 Prodigy, to perfused teeth (30 cm distilled H 2 O), in select areas. (2) Determine the relationship between sealing ability and size of adhesive area (BA) with tensile strength (TS).Methods: Segments of human third molars n 67 sealed with amalgam on their coronal side were connected to a perfusion system (30 cm distilled H 2 O), to measure the basal permeability. Access cavities were drilled through the amalgam to expose dentin (area range: 8.7±20.8 mm 2 ) and measure the permeability of that area. Cavities were sealed with one of the test materials and permeability measured prior to tensile testing. The percentage of decrease in permeability (PPD) that occurred with the different combinations of materials was also measured.Results. Tensile strength: there were no statistically signi®cant differences among groups. Permeability: ANOVA showed that there were statistically signi®cant differences in the mean % decrease in permeability (PPD) among groups p 0:018 : Student±Newman±Keuls test p , 0:05 detected that the mean PPD of F2000 ranked statistically higher than that of SB1. Relationship among variables: a linear correlation was found de®ned by the formula TS 7:47 1 0:008 £ PPD 2 0:23 £ BA; with a signi®cance of the model p 0:0097:Signi®cance: None of the materials studied reduced permeability up to 100%. They all produced low tensile bond strengths (maximum mean value of groups: 5.51 MPa (OPT)). q

“…9 In addition, the relationship between bond strength and microleakage is not clearly understood, and a significant number of studies have failed to demonstrate a relationship between bond strength and microleakage. [12][13][14] Little is known about the effect of the acidity of 1-bottle light-cured adhesives on the microleakage of selfcured composites.

SUMMARYThis in vitro study examined the effect of 1-bottle light-cured adhesives with different acidities on the microleakage of a self-cured composite in Class II restorations. Forty-five Class II cavities were prepared on the proximal surfaces of extracted human intact third molars that were randomly assigned to 3 groups (15 cavities in each group). The following adhesives were applied according to the manufacturer's instructions: Single Bond (Group 1), Excite (Group 2) and One-Step (Group 3). The teeth were restored with a combination of a self-cured resin composite (Concise) and a light-cured resin composite (Filtek P60). After thermocycling (500 cycles at 5°C/55°C) and immersion in 2% basic Fushin, the teeth were sectioned and evaluated for microleakage using a stereomicroscope (16x). Microleakage was scored on a scale of 0 to 3. Kruskal-Wallis analysis showed that there was a significant difference in microleakage values of 3 adhesives with a self-cured composite, and low pH may have contributed to high microleakage values. Also, 2 by 2 comparisons with the MannWhitney U-test revealed a significant difference at the p<0.05 level between Groups 1 and 2 and between Groups 2 and 3. However, there was no statistically significant difference between Groups 1 and 3.

Inverse relationship between tensile bond strength and dimensions of bonded area

It is a known fact that there is a relationship between magnitude of bonded area and laboratory tensile test results. This relationship has been described for a range of areas between 1 and 10 mm 2 , in extracted, nonperfused teeth. The aim of this study is to test this relationship in perfused teeth, with bonded areas ranging from 0.7 to 110.9 mm 2 . Dentin of 92 sound third human molars was exposed and perfused, and three groups of bonded areas (
