Comparison Of The Effect Of Propolis And Gluma Desensitizer On The Management Of Dentin Hypersensitivity

INTRODUCTION Dentin hypersensitivity is commonly characterized by a short sharp pain. This pain is believed to arise from the dentinal tubules that are exposed particularly in response to external stimuli such as evaporative, thermal, tactile or chemical forces.Pain caused by dentin hypersensitivity hampers an individual's day to day activities which includes eating, drinking and often breathing. Since patients do not perceive this as a severe problem they usually do not seek professional treatment. They prefer over the counter products to reduce the sensitivity when the severity increases.

Hydrodynamic theory by Astron and Brannstorm is accepted most widely out of several theories. According to him the flow of the dentinal fluid was dependent upon the mechanical, thermal, evaporative, and osmotic stimuli. This flow in tubules can activate nerves along the entire canal of the pulp causing pain. Therefore, closing the dentinal tubules is the key approach in the management of dentin hypersensitivity. This can be done possibly by crystal precipitation in the tubule. Various methods and agents are being used for its management for instance laser therapy and fluorine preparations, strontium and zinc chlorides, potassium oxalate and dental adhesives.

Gluma desensitizer is an aqueous solution which contains glutaraldehyde 5% and hydroxyethyl methacrylate (HEMA) 35%. It has been found to be an effective desensitizing agent. It blocks the dentinal tubules intrinsically, countering the mechanism of hydrodynamics that eventually leads to dentin hypersensitivity.

Propolis is a naturally occurring resin. It is brown in colour. It is collected by honey bees from exudates of plants and trees. With the secretions and wax it is modified in the beehives. Honey bees use it to protect their hives and repair any opening or damage.

In homeopathic practices it is widely used as an anti-inflammatory and antiseptic agent. Propolis is composed of resins 50-60%, waxes 30-40%, essential oils 5-10%, pollen 5% and other micro elements like aluminium and calcium.
