Comparative study of effectiveness of strontium chloride and formalin containing dentifrices in relieving dental hypersensitivity.

Dental hypersensitivity is a very distinct and annoying clinical complaint. The treatment of dentinal hypersensitivity can be a serious problem in professional dental practice. Many studies have been undertaken and corresponding treatments suggested resulting in various degrees of relief for the patient who is afflicted and concerned that his pain will be further provoked by eating solid or liquid food or by drinking cold or hot beverages. This concern also may cause psychic tension which can reduce the threshold of tolerance to all external stimuli to lower than normal levels.
