OBJECTIVE
Many studies have reported the clinical problems associated with resin composite restorations in NCCLs. None has compared these clinical problems in NCCLs with and without occlusal wear facets. The present study sets out to determine the proportion of NCCLs that presents occlusal wear
The purpose of this study was to evaluate resistance to occlusal wear in high-strength resin posterior teeth (here in after referred to as HS teeth), and to clarify the effects of occlusal adjustment by grinding on the wear resistance of HS teeth. In order to remove the surface layer of HS teeth,
The purpose of this study was to evaluate the clinical effect of using composite resin to fill dental attrition on occlusal surface. Whether the dental attrition had enough space to the material was determined first. Sometimes grinding the sharp and steep cusps or ridges of the opposite teeth was
Unacceptable occlusal wear has been reported for resin-modified glass ionomer cements (RMGICs) placed in permanent molar teeth. Three different surface treatments of a RMGIC were evaluated over periods of up to 2 years for their effects on restoration wear behaviour: (a) sealing with a thin layer of
To investigate the occlusal wear of bulk-fill and conventional flowable resin composites.Four bulk-fill flowable resin composites: (1) Filtek Bulk Fill Flowable Restorative (FB); (2) G-ænial Bulk Injectable (GB); (3) SDR Flow+ (SD); and (4) Tetric EvoFlow The purpose of this study was to investigate the relation between the texture of worn surfaces of composite resins and the maximum wear depth. Three types of composite resins were investigated: a hybrid composite resin consisting of irregular-shaped inorganic filler particles (APX); a composite
Information on the long-term clinical performance of composite resins in posterior restorations is still very limited. The council has classified some composite resins as "provisionally acceptable" for permanent teeth on the basis of information submitted under the guidelines for the acceptance
To investigate the effects of different fillers and their contents on the wear of composite resins, four composites (CS: non-porous spherical silica, AS: porous spherical silica, AZ: porous spherical zirconium silicate, and IS: non-porous irregular-shaped silica) were experimentally prepared using
A series of photo-initiated composite resins, with a Bis-GMA-TEGDMA resin matrix, was investigated in vitro for occlusal wear, surface roughness, diametral tensile strength, and hardness. The materials contained mixtures of ground quartz (macrofiller, 3 microns) and colloidal silica (microfiller,
