1. Ouellet, D., "A Simple Method Measuring Composite Resins Polymerization Shrinkage," Journal of Dental Research, Vol. 76 (1996): 291.

Marathon demonstrated the least amount of polymerization shrinkage compared to other light-cured systems. Because polymerization shrinkage is directly related to postoperative sensitivity, using Marathon and Tenure dramatically reduced sensitivity.

2. Scherer, W., Leinfelder, K., "Bulk Placement of Composite Resin in Class II Preparations," Esthetic Dentistry Update, Vol. 7 (1996): 28-30.

The technique of bulk placement of composite resin, Marathon and True Vitality, was presented in this article. The technique described allows practitioners to place a posterior composite resin material in class II preparations in a bulk-filled manner quickly and efficiently without the occurrence of postoperative sensitivity and fracture of the enamel walls.

3. Ouellet, D., "Considerations and Techniques for Multiple Fill Direct Posterior Composites," Compendium, Vol. 16 (1995):12.

Dual-cured Marathon polymerizes independent of a curing light and eliminates the need for incremental layering. This technique offers better quality restorations with less chairtime.

4. Godder, B., et al., "Direct-Shrinkage Composite Placement," General Dentistry (1995): 444- 446.

The purpose of this study was to compare microleakage of two different composite placement techniquesincremental vs. bulk filling. No significant differences of microleakage were discovered between the two different methods.

5. Medige, J., "Effects of Restorative Materials on Cuspal Flexure," Quintessence International, Vol. 26 (1995): 571-576.

Analysis compares the effects of tooth strengthening with different restorative materials in a tooth subjected to cuspal loading in relation to surface strains. Linear strain gauges were used. The results demonstrated a statistically significant difference in strength between teeth restored with Tenure/Marathon V and those restored with either amalgam or Scotchbond 2/P-50. The combination of Tenure/Marathon demonstrated a tooth strengthening effect at both proximal and buccal sites.

6. Kasloff, Z., et al, "Cuspal Deflection Studies Using an Electronic Probe to Evaluate Restorative Materials and Bonding Agents," Esthetic Dentistry Update, Vol. 6 (1993): 10-12.

Studies demonstrated that large cavity preparations in posterior teeth weaken tooth structure even if restored, cuspal fracture can occur under occlusal loading. The purpose of this study was to measure the amount of deflection that would occur when a vertical load is applied to the cuspal incline of a tooth. The results demonstrated that the combination of Tenure/Marathon compared with amalgam significantly increased resistance to deflection. Amalgam alone provided an insignificant amount of resistance to deflection.
