“…These findings are in accordance to the qualitative results presented in Figure 5. The present results are also in qualitative agreement with in-vivo experiments of other authors which showed that the F (Fortify ® ) sealant can improve the wear resistance of composite resins 5,9 . Other in-vitro studies have also reported that both F and BC sealants can reduce the wear 12,21 .…”

“…Generally, dental sealants present low viscosity and surface energy, being able to penetrate, fill in and cover surface defects and, therefore, improve the resin surface by filling the microfissures and small irregularities usually presented in such composites. Further, they improve marginal integrity, reduce microleakage, decrease surface roughness and increase wear resistance [8][9][10][11][12][13] . Beun et al (2012) 14 have shown that resin-based pit and fissures sealants commercially available are effective on preventing pit and fissures.…”

Relation between in-vitro wear and nanomechanical properties of commercial light-cured dental composites coated with surface sealants

This work investigates the correlation between the in-vitro wear resistance and the nanomechanical properties of dental sealants commercially available. Mechanical properties, namely hardness (H) and elastic modulus (E), were assessed by nanoindentation technique. The coated samples presented lower H and E values than the Z250 composite resin substrate. Such measurements were used to calculate H/E ratios. Wear tests were carried out in water by using a pin-on-plate apparatus. Scars formed on the samples were qualitatively examined by optical microscopy, while their wear depths were measured by contact profilometry. Based on the findings, an empirical correlation between the wear depths and H/E was obtained. A high H/E ratio was associated to surfaces with enhanced wear resistance. For the tribological conditions here employed, the H/E ratio could be, therefore, considered a useful parameter for ranking the in-vitro wear of dental sealants.

“…4 Although long-term studies are not currently available to discuss the efficacy of composite surface sealants, short-term studies have shown that microcracks caused by the trauma of finishing procedures are resealed. 17 Microcracks particularly at the cavosurface margins can propagate overtime, hence it is logical that the use of surface sealants postoperatively decrease the surface wear and increase the longevity of direct resin restorations.…”

Aim:The purpose of this study was to assess the knowledge and practices of Saudi dentists in finishing and polishing composite restorations. Materials and methods:A cross-sectional questionnaire-based study was conducted among 306 Saudi dentists from March to April 2012. The collected data were analyzed using Microsoft Excel 2010 program and descriptive statistics were obtained. Results:Completed questionnaires were returned by 191 participants, giving a response rate of 62.4%. 115 (65.7%) respondents are using fine diamond finishing burs for finishing occlusal surfaces, 82 (48%) used fine aluminum oxide finishing discs for finishing facial surfaces, 130 (76%) used diamond finishing strips for finishing interproximal surfaces.121 (63.4%) respondents were of the view that the type of filler content has a major influence in providing color stability to the composite restoration and 137 (72.1%) believed nano-composites provided enhanced color stability. Conclusion:Dentists in Saudi Arabia are aware of the benefits of proper finishing and polishing of composite restorations. They however need to use finishing and polishing burs, disks, strips and pastes in a sequential series. Usage of composite polishing pastes and composite surface sealants should be emphasized in undergraduate curriculum.

The purpose of this study was to evaluate the difference of surface roughness of composite resin according to composite resin type, polishing methods, and use of resin sealant.Two hundred rectangular specimens, sized 8 × 3 × 2 ㎜, were made of Micro-new (Bisco, Inc., Schaumburg, IL, U.S.A) and Filtek Supreme (3M ESPE Dental Products, St. Paul, MN, U.S.A.), and divided into two groups; Micronew-M group, Filtek Supreme-S group. Specimens for each composite group were subdivided into five groups by finishing and polishing instruments used; M1 & S1 (polyester strip), M2 & S2 (Sof-Lex disc), M3 & S3 (Enhance disc and polishing paste), M4 & S4 (Astropol), and M5 & S5 (finishing bur). Polished groups were added letter B after the application of resin surface sealant (Biscover), eg, M1B and S1B.After specimens were stored with distilled water for 24 hr, average surface roughness (Ra) was taken using a surface roughness tester. Representative specimens of each group were examined by FE-SEM (S-4700: Hitachi High Technologies Co., Tokyo, Japan). The data were analysed using paired t-test, ANOVA and Duncan' s tests at the 0.05 probability level. The results of this study were as follows;1. The lowest Ra was achieved in all groups using polyester strip and the highest Ra was achieved in M5, S5 and M5B groups using finishing bur. On FE-SEM, M1 and S1 groups provided the smoothest surfaces, M5 and S5 groups were presented the roughest surfaces and voids by debonding of filler on the polished specimens. 2. There was no significant difference in Ra between Micronew and Filtek Supreme before the application of resin sealant, but Micronew was smoother than Filek Supreme after the application of resin sealant. 3. There was significant corelation between Ra of type of composite resin and polishing methods before the application of resin sealant (p = 0.000), but no significant interaction between them after the application of resin sealant. On FE-SEM, most of composite resin surfaces were smooth after the application of resin sealant on the polished specimens.※ 이 논문은 2006년도 조선대학교 학술연구비의 지원을 받아 연구되었음.
