Wear resistance of three direct resin composites in artificial Saliva at varying pH levels

Under the tested *<i>in vitro</i>* conditions, Kerr SonicFill resin demonstrated wear behavior most comparable to natural enamel across varying pH environments, showing stable performance. This suggests it could be a suitable choice for dental restorations requiring durability under varying pH conditions, though direct extrapolation to clinical performance requires caution. The increased wear of natural enamel at alkaline pH was an interesting finding warranting further study.
