The Problem

Research shows that 30% of patients feel post-operative sensitivity after posterior resin restorations.1 Hypersensitivity can cause restoration replacement and the additional loss of tooth structure that happens whenever restorations are removed.2 The prevailing theory concerning the cause of dentin hypersensitivity is based on hydrodynamics and was initially developed by Brännström3,4 and further developed by others such as Pashley.5

Brännström et al. suggests that sensation of pain (hypersensitivity) can occur from the movement of fluid within the dentin tubules. When dentin tubules are exposed to external stimuli, such as cold, warmth or osmotically active substances, the dentinal fluid will flow.  This flow results in the stimulation of the odontoblasts and nerve fibers leading to the pulp, which patients perceive as pain.

The Solution

Adhese Universal is a dental bonding agent that has an integrated desensitizing effect. It forms a reliable dentin seal via a homogenous adhesive layer with defined resin tags, which prevents the movement of fluid in the dentin as well as post-operative sensitivity associated with that movement. No separate desensitizer is required when Adhese Universal is used due to its "Desensitizing Effect."

Studies show that Adhese Universal results in virtually no post-op sensitivity, thanks to its integrated desensitizing effect.
