Deflection Studies Using an Electronic Probe to Evaluate Restorative
Materials and Bonding Agents,” _Esthetic_Dentistry_Update_, Volume 6,
No. 1, February 1995:10–13.
Several studies have shown that large-cavity preparations in posterior
teeth weaken tooth structure, and if restored, under occlusal loading
cuspal fracture can occur. This study measured the amount of deflection
that occur when a vertical load is applied to the cuspal incline of a
tooth. The Tenure®-Core Paste combination, compared with amalgam,
significantly increased resistance to deflection. The following table
describes the results.
