A Study on the Mechanism of Pain Elicited from the Dentin.

The article presents a study which examined the mechanism of pain found in the dentin and the role of odontoblasts in the pain response. Absorbent paper was applied to exposed dentin to prove that exposed outer apertures of dentinal tubules register pain when in contact with absorbent materials. The mechanical stimulation of pain fibers at the pulpo-dentinal border is discussed.
