“…However, optimum composition of fillers should be used to obtain optimized physical, mechanical and clinical performance [37]. For comparative investigation of effect of ceramic nanofiller and glass ionomer cement, the most commonly used mechanical characterization methods include compressive strength (CS), flexural strength (FS), diametral tensile strength (DTS), fracture toughness (FT), microhardness (Knoop (KHN) or Vickers (VHN)), wear rate (WR), fatigue and creep [38][39][40].…”

In the present study, comparative analysis of glass ionomer and nanofillers in the performance of dental composite has been reviewed. In dental composite, a number of particulate fillers specifically nanoparticle are being tested and used. A new approach has been tried and investigated to replace expensive nanofillers with the other filler such as glass ionomer. There is a strong need to understand the scientific method, to conduct the clinical trial, and to perform the laboratory test to evaluate role of each parameter, constituent in the performance of dental composite. The present research reviewed the recent finding, possible opportunity and challenges for use of glass ionomer as replacement of nanofiller in dental composite. The existing literature on the favorable and non‐favorable side of glass ionomer is critically evaluated. The major aspect considered in the present review was to evaluate the surface roughness, mechanical properties and wear properties. The present article attempted to provide a state‐ of‐ the‐art analysis of fabrication method, surface treatment method and comparative analysis on role of particulate filler versus glass ionomer on the performance based on mechanical and wear testing mechanism.

“…The loss of an oxygen-inhibited layer over time reduces the chemical bonding capability of resin composite. A polished resin composite surface reduces the micro-mechanical bonding capability of an old composite with a new one [ 11 ]. Considering these factors, it is essential to explore and establish the best repair protocol that can achieve superior bond strength and durable repair.…”

This study investigates the impact of mechanical alteration on resin composite surfaces and its subsequent effect on repair bond strength. A total of 100 resin composite disks were prepared and were allocated for 24 h or 1 year of artificial aging. Specimens were embedded in epoxy resin, and the composite surfaces were mechanically altered using either diamond burs or air abrasion with aluminum oxide or glass beads. A universal bonding material was applied and a 2 mm circular and 3 mm high repair composite cylinder were prepared using a Teflon mold. Then, the specimens were tested for their shear bond strength, and the de-bonded specimens were observed under a scanning electron microscope to determine the failure pattern. SPSS 26.0 statistical software was used to analyze the data. Two-way ANOVA showed a statistically significant effect of mechanical alteration and aging on the shear bond strength of S-PRG-filler-based resin composite (p < 0.05). Surface modification with a fine diamond bur showed a significantly higher bond strength in both 24-h- and 1-year-aged specimens. Surface modification with alumina significantly increased the bond strength of 1-year-aged specimens; however, it was statistically insignificant for 24 h-aged specimens. Mechanical alteration with a fine diamond bur and 50-micron alumina can improve the repair bond strength of the composite.
