    Study Notes

    Dentine Hypersensitivity

    • Dentine hypersensitivity is a common oral health issue.
    • Pain is short-lived, sharp, and quickly resolves.
    • Pain is typically triggered by stimuli such as hot, cold, or acidic substances.
    • The pain is usually localized to a specific area or tooth.

    GDC Learning Outcomes

    • Dental practitioners need to describe oral diseases and their impact on diagnosis and treatment.
    • Aetiology and pathogenesis of oral diseases need to be explained.
    • Comprehensive and contemporaneous patient histories are essential for diagnosis.
    • Changes in patients' reported oral health status must be recognized and addressed.
    • The role of all involved dental team members in treatment plans must be understood.

    Pre-reading

    • Students should review histology of enamel and dentine prior to the session.

    Learning Objectives

    • Define dentine hypersensitivity based on its symptoms.
    • Explain the mechanisms leading to dentine hypersensitivity.
    • Identify and understand the factors that contribute to dentine hypersensitivity.
    • Outline the dental professional's role in managing dentine hypersensitivity patients.

    Dentine Hyper-Sensitivity (Page 6)

    • The issue may only be affecting a specific area of one tooth.
    • Patients describe having too much of certain aspects of quality.
    • Patients describe having a strong reaction to small changes.

    Pain Presentation

    • Pain from dentine hypersensitivity is characterized by short duration, rapid onset, sharp pain, and quick resolution.
    • These symptoms are observed only in the absence of additional symptoms.

    Cause of Pain

    • Pain arises from a combination of stimulus and a susceptible tooth.

    Tooth Susceptibility (Page 11)

    • Exposed dentine and cementum makes a tooth susceptible to hypersensitivity.
    • The tooth's anatomy plays a critical role in susceptibility.
    • Enamel, cementum, and dentine are involved in tooth construction.

    Dentinal Tubules (Page 12)

    • Dentinal tubules connect the dentine to the pulp.
    • The pulp contains nerves and blood vessels.

    Theories on Pain Registration

    • Theories include direct nerve innervation, odontoblast receptors, and hydrodynamic mechanisms.
    • Hydrodynamic theory is the most accepted theory for explaining the pain mechanism in dentine hypersensitivity

    Hydrodynamic Theory

    • Fluid movement through dentinal tubules can trigger pain.
    • Water makes up a significant part of dentine.

    Stimuli

    • Thermal changes (hot and cold), chemical agents (acid, whitening agents), and mechanical forces (brushing, eating) can trigger pain.

    Aetiology Definitions

    • Dentine hypersensitivity is pain from exposed dentine reacting to stimuli.
    • Stimuli such as chemical, thermal, or tactile stimuli.
    • Pain not explained by other dental defects or problems.

    Causes of Exposed Dentine

    • Natural morphology (5%, 30%, and 60% ratios of enamel overlap in relation to the gum line)
    • Localized gingival recession (caused by tooth brushing, nail biting, piercings, and opening items).
    • High frenum.
    • Periodontal disease.
    • Lack of keratinised tissue.
    • Orthodontics.
    • Generalised gingival recession post-periodontal treatment.
    • Tooth surface loss (attrition, abrasion, erosion, abfraction)

    Diagnosis Procedures

    • Examination (morphology and dentine exposure)
    • History taking (identification of the problem)
    • Testing (pain elicitation (3 in 1), identifying painful areas)
    • Comprehensive history (characteristics of pain, frequency, trigger factors)

    Dental Hygienists and Therapists Role

    • Identifying the cause of dentine hypersensitivity.
    • Identifying aetiological factors (e.g. medical, behavioral, or environmental causes).
    • Educating patients about the problems and their solutions.
    • Referring to more specialized dental professionals (e.g. general dentists) when necessary.
    • Providing preventative management and advice.

    Home Remedies

    • Use of desensitizing toothpaste.
    • Avoidance of acidic or extremely hot/cold beverages.
    • Use of fluoride treatments.

    Mechanisms of Action (Page 33)

    • Reducing stimulus.
    • Occluding tubules.
    • Desensitizing nerves.
    • Preventing further exposure.

    Treatment Agents

    • Agents such as calcium phosphosilicate, calcium triphosphate, bioactive glass, and others to occlude the dentinal tubules to relieve hypersensitivity.
    • Dentists use agents such as fluoride, arginine to desensitize nerves.

    Clinical Examination

    • Tooth morphology and assessment of dentine exposure are important.
    • Pain elicitation, through testing stimuli, pinpoints painful areas and confirms dentine hypersensitivity.

    Professional Treatment

    • Medications and other specialized treatment options by dentists.

    Summary

    • Identifying symptoms; the nature, severity, location, etc.
    • Identifying the cause/aetiology.
    • Providing education to the patient.
    • Referral to a general dentist.
    • Providing advice for self-care.
    • A review of dentine hypersensitivity.
    • Guidelines for general dentistry on dentine hypersensitivity.
