According to the particle size, composites are classified into micro-filled, macro-filled, and hybrid: (b) An important feature that determines the physical property of composite is its filler content. Increasing the concentration of the filler, either micro, macro, or hybrid, the quantity of resin is inferior, reducing the weaker and the more critical phase. Consequently the abrasion resistance, the hardness, and the elasticity module increase, and the coefficient of thermal expansion and the polymerization shrinkage decrease.
Lower-viscosity composites, with lower content of particles, allow better wetting of the tooth and are prepared as flowable composites. They are very useful when applied on the bottom of the cavity, for filling the undercuts, for fissure sealing, and for adhesive cementation. Flowable composites confer to the obturation elasticity to absorb the shrinkage stress. The macro-filled composites have size particle ranging from 5 to 25 μm. The filler content is approximately 70–80 % by weight. The surface became rougher because of the resin wear with exposure of the particle on the surface, losing shine and smoothness.
5 Diagnosis A correct diagnosis of caries and the determination of pulp status must precede any therapeutic procedure. The medical history of the patient, related to recent or past sensitivity or tooth pain or to past dental trauma, must be investigated. Even the type of pain, to mastication or consequent to chemical or thermal stimuli, is important for diagnosis. The occlusal carious lesions are detectable through a direct and close inspection of the oral cavity, improved by magnification devices (loops or operating microscope); the visit must follow a professional dental hygiene session, so that when the teeth are dry and free of deposits and pigmentations, a better acquisition of visual information is possible.
