Study Notes

Various stimuli can elicit a pain reaction, including tactile, thermal, evaporative, osmotic, and chemical.
Hypersensitivity is characterized by sharp, short, or transient pain in response to non-noxious stimuli.
Dentin is composed of fluid-filled dentinal tubules that are potentially innervated with nerve fiber endings.
Gingival recession is a common cause of hypersensitivity.
Attrition, abrasion, and erosion can also lead to hypersensitivity.
Hydrodynamic theory explains the transmission of stimuli from the outer surface of the dentin to the pulp.
Natural desensitization mechanisms include sclerosis of dentin, secondary dentin, smear layer, and calculus.
Hypersensitivity is most commonly found among 30- to 40-year-olds and in women.
Pain perception can be impacted by various factors such as stress, fatigue, and health beliefs.
Diagnostic techniques and tests include visual and radiographic assessments, percussion, and mobility testing.

Bite stick used to assess tooth fracture pain
Transillumination with high-intensity light to visualize cracked tooth
Dye may indicate fracture line
Pulpal pathology assessment
Thermal pulp tests used for assessment
Electric pulp tests used for assessment
Techniques used to diagnose tooth fractures
Bite stick and transillumination are non-invasive techniques
Pulp tests involve minimal discomfort
Early detection of tooth fractures can prevent further damage.
