Since the first resin-based light-cured dental composites were introduced in the 1970s, significant advancements have been realized in resin and filler technology, and today more than 70 different brands of composite exist on the market. Today's clinicians can be easily confused about the subtle differences between the many available composite materials and may find it more difficult to make the correct decision about which material is best for each clinical situation.

To simplify decision-making and to offer a composite that can insure excellent performance in all clinical situations, DENTSPLY Caulk has introduced TPH Spectra Universal Composite. This new composite is based on the resin technology of TPH3 and contains nanohybrid- and micro-filler components. dental instruments uk The result is a composite that has the potential to perform well in either the anterior or posterior, and should have tooth-like translucency, improved polishability and color stability, and good wear resistance.2-4  TPH Spectra also comes in two handling choices: A creamy light-viscosity formulation, and a packable high-viscosity formulation. For both viscosities, the physical properties are similar. Because handling preference is subjective and highly individualized, practitioners are now able to select the right viscosity for all clinical situations. 

Restorative outcomes can be influenced by simplified shading options when the restorative material selected has excellent blending capability. Often called the "chameleon effect," composite blending with adjacent tooth structure is dependent on material translucency and shade, and is most pronounced in small- to moderate-sized restorations. Building and improving from the previous TPH3 composite formulation, TPH Spectra has a refractive index that falls directly between enamel (1.63) and dentin (1.54).5-6 Put simply, this means that when light hits TPH Spectra it appears indistinguishable from natural tooth structure.  dental equipment
In order to make shade selection simpler, it is available in the seven most popular shades: B1, A1, A2, A3, A3.5, A4, and C2.

Intraoral exam reveals a lesion on the disto-occlusal surface of tooth No. 29 (Fig. 1). After verifying the medical history and reviewing the radiographs, a direct composite resin restoration of the disto-occlusal of No. 29 was treatment planned.  
Anesthesia was achieved with one carpule of 4% Articadent? with 1:100,000 epinephrine (DENTSPLY Pharmaceutical) via buccal infiltration. Caries excavation was completed using a 330 carbide bur on a high-speed handpiece and a #4 round bur on a low-speed handpiece. The preparation was verified caries-free with Snoop caries detector (PULPDENT Corp). A rubber dam was placed after preparation was completed.
