What is dentin hypersensitivity?

Pain from exposed dentin tubules as a response to external stimuli (cold, heat, air, sweet, sour)

What are some patient behaviors that can trigger a hypersensitivity pain response?

Bulimia, whitening, brushing hard, or clenching/grinding

What condition precedes the development of dentinal hypersensitivity?


Describe the role of dentinal tubules in the development of hypersensitivity?

If they are exposed, the stimuli moves through the tubes to the pulp causing the pain

There are many factors that contribute to gingival recession, subsequent root exposure, and potential dentin hypersensitivity. Name as many as you can.

Oral piercings, narrow zone of attached gingiva, improper OHI, facial orientation of teeth, erosion, periodontal disease and treatment, restorative treatment, attrition, tight or short labial frenum, periodontal surgery, improper brushing, whitening

What are two factors that can contribute to erosion on an exposed root surface?

citrus drinks, carbonated drinks, acid reflux, bulimia

How does abfraction occur?

A microscopic lesion commonly found on the gingival margin and looks like a V-shaped notch in the cervical area

Which natural desensitization mechanism is related to narrowing of the inside wall of the dentin tubules?

Sclerotic Dentin

A smear layer can reduce dentin hypersensitivity by blocking the dentin tubules, what causes a smear layer?

It accumulates after root instrumentation using toothpaste with abrasive particles, attrition or abrasion cutting with a burr

What is a negative effect of a smear layer?

May increase your risk for hypersensitivity by root planning and exposing the collagen fibers which may increase the migration and attachment of PDL cells

Two different patients can experience pain from hypersensitivity in different ways. Why is pain perception subjective?

It doesn't feel the same for everyone and everyone feels is differently, what is painful to one may be tolerated by one

What are some components to include in your patients dental history of hypersensitivity?

Self report of symptoms, scales, diet analysis, parafunctional habits, stressors, what they are sensitive to, when the sensitivity started, where it is located, what they are sensitive to

What are 2 patient response-related diagnostic tests that can be used to determine location and severity of tooth pain?

Biting forces on bite stick, percussion test

What are some trigger questions you can ask your patient about?

Hot or cold, stop immediately upon removal of the stimuli, how bad is your pain, how long it lasts, where it is located, when it started, what are you sensitive to

You can use VRS to rate the level of pain your patient is feeling. If your patient describes her tooth-related pain as a level 3, what does she mean?

significant discomfort and lasted longer than 10 seconds

Identify at least 5 clinical techniques used to differentiate among the variety of potential causes for dental pain

radiographic exam, occlusal exam, dental history, percussion, clinical exam, transillumination

Not one best method has been identified for the treatment of hypersensitivity. Treatment options offered to the patient should begin with the most _________ and least ___________ measures.

Conservative, least invasive

List five factors that you can take into consideration when selecting a desensitizing agent

no staining, consistent, acceptable taste, prescribe an agent that takes little time, no pulp irritation, rapid lasting effect, easy to apply and no harm

What patient action, if used as part of daily oral hygiene regimen, can contribute to the formation of a smear layer or reparative dentin and thereby reduce hypersensitivity?

burnishing with wooden pick

identify the ingredients in over-the-counter (OTC) desensitizing dentifrices

Potassium nitrate

Identify therapeutic ingredients that block the pain response by occluding the dentinal tubules

fluorides, oxalates, gluteraldehyde, calcium carbonate, arginine

List 3 means of covering exposed dentinal tubules at the CEJ

Unfilled or partial resins, dentin bonding agents, composite and glass ionomer, soft tissue gates

The highest prevalence of hypersensitivity is found in __________. Prevalence and severity ___________ in older folks due to the occurrence of natural mechanisms of desensitization.

Periodontally involved patients, decreases

What are 5 stimuli that elicit pain reaction?

Tactile, thermal, evaporative, osmotic, chemical

What is currently the accepted explanation for the transmission of stimuli from the outer surface of the dentin to the pulp?

Hydrodynamic theory
