    Study Notes

    Diseases of Pulp

    • Pulp is a delicate connective tissue containing blood vessels, nerves, and undifferentiated connective tissue cells.
    • Pulp inflammation (pulpitis) is a common disease. Untreated, early pulp inflammation can lead to periapical inflammation.
    • Pulp anatomy significantly impacts inflammation. The pulp's lack of collateral circulation and the constricted apical foramen limit its blood supply and venous return.
    • The pulp's containment within the hard dentin chamber restricts swelling, causing vessel compression and potential pulp necrosis.
    • Lack of proprioceptors in the pulp makes pain localization difficult.
    • Pain from the pulp can be felt in multiple teeth on the affected side, or referred to distant sites like the ear.

    Significance of Pulp Anatomy in Inflammation

    • The absence of collateral circulation limits the pulp's blood supply.
    • The constricted apical foramen restricts venous return.
    • The hard dentin chamber prevents pulp swelling, potentially leading to vessel compression and pulp necrosis.
    • The lack of proprioceptors makes pain localization difficult.

    Etiology of Pulp Inflammation (Living Irritants)

    • Bacteria: Gain access through dental caries, tooth fractures, blood-borne infections (hematogenous spread), or through deep periodontal pockets via accessory root canals.

    Etiology of Pulp Inflammation (Non-living Irritants)

    • Chemical: Free phosphoric acid in cements, arsenic resin monomers, monomers in composite restorations, and sterilizing agents (e.g., alcohol).
    • Thermal: Large metallic restorations, heat-evolved during cavity or crown preparations, heat from cement setting (e.g., acrylic resin).
    • Electric: Presence of two dissimilar metals (galvanism).
    • Mechanical: Trauma, abrasion, accidental pulp exposure (iatrogenic), traumatic occlusion, expansion of trapped air, and crushing of blood supply.

    Classification of Pulpitis

    • According to type of inflammation: Focal Reversible Pulpitis, Acute Irreversible Pulpitis, Chronic Irreversible Pulpitis.
    • According to extent of pulp involvement: Partial Pulpitis, Total Pulpitis.
    • According to communication with oral cavity: Closed Pulpitis, Open Pulpitis.

    Focal Reversible Pulpitis (Pulp Hyperemia)

    • Definition: Active dilation of pulpal blood vessels, considered reversible if the irritant is removed before significant damage.
    • Etiology: Any previously mentioned etiologic factors.
    • Pathogenesis: Vasodilation of blood vessels and increased capillary permeability, fluid exudate causing edema, increased blood viscosity, and slowed blood flow.
    • Clinically: Sensitivity to thermal changes (particularly cold), sharp shooting pain, pain resolves rapidly on stimulus removal, pain not easily localized, increased sensitivity to electrical pulp test.
    • Microscopically: Dilated blood vessels, edema in connective tissue, intact odontoblastic layer.
    • Treatment: Removal of the cause (e.g., decay).
    • Prognosis: Reversible with removal of irritant.

    Acute Irreversible Pulpitis

    • Definition: Acute inflammation of the dental pulp, often the result of untreated reversible pulpitis.
    • Etiology: Pulp hyperemia, exacerbation of chronic pulpitis, or the previously mentioned etiologic factors (bacterial, chemical, thermal, electric, mechanical).
    • Pathogenesis: Fluid exudates, swelling of odontoblastic nuclei, possible blood flow slowing and leukocyte migration, possible necrosis and pus formation, and the potential for pulp abscess.
    • Clinically: Sensitivity to thermal changes, pain described as sharp lancinating pain that is sustained after stimulus removal; pain localized, increased sensitivity to electrical pulp test.
    • Microscopically: Destruction of the odontoblastic layer, dilation of blood vessels, edema in connective tissue, inflammatory cell infiltration (polymorphonuclear leukocytes), focal tissue destruction, and pus (pulp abscess) formation.
    • Treatment: Extraction of the tooth or endodontic treatment.

    Chronic Irreversible Pulpitis

    • Definition: Chronic inflammation of the dental pulp, often progressive and characterized by absence of acute symptoms.
    • Etiology: Following acute pulpitis or developing de novo; low-virulence causative agents are often the cause.
    • Clinically: Pain may be intermittent, dull ache, tooth may be less reactive to thermal stimulation, diminished response to electrical pulp test, and insensitivity to percussion.
    • Microscopically: Increased fibroblastic activity resulting in granulation tissue replacement of pulp tissue, continued inflammatory cell infiltration (plasma cells and lymphocytes), possible disruption of odontoblastic layer based on severity.

    Chronic Open Ulcerative Pulpitis

    • Definition: Pulp exposed, granulation tissue replacing the dentin roof on the pulpal surface due to decay.
    • Clinically: Pain ranging from mild to aggravated, particularly when food is impacted.
    • Microscopically: Granulation tissue with chronic inflammatory cells, possible collagen fiber formation at the pulp's surface.
    • Treatment: Extraction of the tooth or endodontic treatment.

    Chronic Hyperplastic Pulpitis (Pulp Polyp)

    • Definition: Pulp hyperplasia, typically in a protected area. Wide access to blood supply.
    • Etiology: Usually develops in readily accessible areas for blood supply, often in response to pulp irritation.
    • Clinically: Frequently displayed in deciduous teeth or permanent first molars, appearing as a red structure protruding from a large carious cavity; less sensitive to manipulation, and fewer nerve endings.
    • Histopathology: Granulation tissue with chronic inflammatory cells and may exhibit epithelization.
    • Treatment: Extraction of the tooth or endodontic treatment

    Pulp Necrosis (Pulp Gangrene)

    • Definition: Complete death of the pulp tissue due to ischemia (insufficient blood supply).
    • Etiology: Often results from untreated acute or chronic pulpitis, or trauma.
    • Clinically: Cessation of all symptoms.
    • Microscopically: Empty pulp chambers or canals, necrotic tissue.

    Comparison of Different Pulpitis Types (Table)

    • This table summarizes key differences in pulpitis types (including considerations like pain characteristics, reversibility, and various diagnostic test responses). (Detailed information on the comparison of Pulpitis types is located in page 13 of the text)
