“…It has been stated that the best surface finish on a composite resin is attained by permitting the resin to set in contact with a matrix and the procedure has been advocated by manufacturers. That view has also been supported by writers such as Chandler, Bowen & Paffenbarger (1971), Messing & Ray (1972) and Deubert & Jenkins (1972). Such a surface may, nevertheless, be far from ideally smooth.…”

“…Various hardness tests have been employed (Peterson et al, 1966;Von Fraunhofer, 1971;Valcke, 1978). Scanning electron microscopy has been employed by a large number of investigators including Chandler et al (1971), Beech & Brown (1972), Hannah & Smith (1973), Gray & Gavin (1975), Kanter, Koski & Graham (1976) and Valcke (1978). Surface roughness has been observed with the aid of profilometers by Glantz & Larsson (1972), Kanter et al (1976), Horton et al (1977), andde Wet (1978).…”

Four direct filling resins were examined in order to compare the roughness and porosity of different materials, mixed by different methods. From each material six specimens were prepared. Each specimen was formed against a Mylar sheet and the Mylar-formed surface was examined. Subsequently it was trimmed and polished and re-examined. Each specimen was examined with a microscope using incident light and employing an automatic point-counting attachment in order to assess the percentage surface (apparent) porosity. Each specimen was also examined with a stylus-type profile meter. Rt (total roughness height) was recorded for all specimens and Ra (roughness average) was recorded for all polished specimens. The findings support the conclusion that a capsulated resin without an inorganic filler yields a better surface than other resins.

“…Otherwise, the finishing tool only removes the soft resin matrix, leaving the filler particles protruded. 24,31 Also, the ormocer (Definite) presented a smooth surface finish by Astropol polishers. It can be explained by the presence of multigrain types of caoutchouc, silicone oxide, aluminum oxide, titanium oxide, iron oxide, and diamond dusts impregnated into the polishers.…”

Analysis of variance revealed highly significant differences between the materials for the Ra roughness parameter at each finishing and polishing system used (p < 0.05). On the one hand, Filtek P90 (3M ESPE Dental Products, Seefeld, Germany) and Definite (Degussa, Dental Centrum, Hanau, Germany) provided the smoothest surface finish (Ra) when they were finished and polished with a series of Sof-Lex pop-on disks (3M ESPE Dental Products) and Astropol (Ivoclar Vivadent, Schaan, Liechtenstein), respectively. On the other hand, Filtek P60 (3M ESPE Dental Products) presented the roughest surface when it was finished with Fini disks (Jeneric/Pentron Clinical Technologies, Wallingford, CT, USA). Scanning electron microscope images indicated a uniform surface topography for Filtek P90 with most finishing/polishing systems. Contrary to CompoSite polishers (Shofu Inc., Kyoto, Japan), Astropol showed the smoothest surface finish with most of the investigated composites. CLINICAL SIGNIFICANCE The smoothest surface finish was achieved by most of the finishing/polishing systems investigated specifically on cationic (Filtek P90) and organically modified ceramics (Definite) composites compared with dimethacrylate-based composites, suggesting their successful clinical use.

“…The discussion on how to polish the surfaces of composite fillings has not yet been settled (Chandler, Bowen & Paffenbarger, 1971;Hannah & Smith, 1973;McLundie & Murray, 1974;Heath «fe Wilson, 1976;Davidson & Tas, 1978). They all tried to abolish the surface roughness using several methods.…”

The use of glazing materials for finishing dental composite resin surfaces

The purpose of this study was to investigate the retention of glazes on polished composite surfaces. Sections of three differently resin-coated composites have been prepared in vitro and examined by scanning electron microscopy (SEM). All samples showed an interrupted interstice between glaze and composite. After ultrasonic cleaning of the composite surface, the empty porosities do not provide enough mechanical retention to retain the glaze. The difference in physical properties of both components may explain the releasing ofthe sealant. Surface conditioning with H3PO4 (37%) enhances the mechanical retention on coarse-grained composites. The same effect occurs using chloroform. This chemical also realizes a partial chemical bond. However, it has been proved to be insufficient to prevent glaze releasing. Consequently, the use of glazing materials seems unsuitable for a permanent gloss on composite surfaces.
