    Study Notes

    Denticles and Pulp Chamber

    • True denticles are localized masses of calcified tissue resembling dentin, exhibiting tubular structure.
    • Coronal pulp is centrally located in the crown, mirroring the shape of the dentin surface.
    • Extensions of the pulp chamber exist beneath cusps to provide blood supply.
    • Pulp chamber can act as a pathway for infections between the pulp and periodontal ligament.

    Structural Features of the Pulp

    • Central pulp region contains large nerve trunks and blood vessels.
    • Structural integrity ensures proper function of the pulp and surrounding tissues.

    Root Resorption

    • Root resorption refers to the breakdown of tooth root structure due to cell activity.
    • Physiologic root resorption occurs during normal tooth shedding in children.
    • Pathologic root resorption can occur due to infections, tumors, or other conditions.
    • Types include external resorption (tissue reaction in periodontal/pericoronal tissues) and internal resorption (reaction from pulpal tissue).

    Tumors and Cysts

    • Tumors can be benign or malignant and may cause root resorption.
    • Cysts are closed sacs lined with epithelium, filled with fluid or semisolid material.

    Clinical Features of Inflammation

    • Chronic inflammatory reactions in pulp tissue can lead to granulomas and potential necrosis.
    • Loss of substance in the tooth structure can stem from prolonged inflammatory conditions.

    Enamel Hypoplasia

    • Enamel hypoplasia can result from local infection or trauma, primarily affecting maxillary incisors or premolars.
    • Specifically affects single teeth, referred to as Turner’s tooth and associated with Turner’s hypoplasia.

    Diseases of the Pulp

    • Pulp diseases are classified into acute and chronic forms based on their inflammatory nature.
    • Acute pulpitis may arise from previous inflammation leading to chronic conditions.

    Chronic Pulpitis

    • Chronic pulpitis stems from unresolved acute pulpitis, typically with milder symptoms.
    • Open (communicates with oral cavity) and closed (no communication) forms exist.
    • Histological features include vascular dilatation and edema fluid accumulation.

    Treatment and Prognosis

    • Resolutions like pulpotomy can relieve discomfort; however, extensive damage leads to poor prognosis with limited recovery options.
    • Treatments involve the removal of infected tissue and possibly filling root canals with inert materials.
    • Severe cases of pulp insults may lead to necrosis and necessitate root canal therapy as the primary intervention.
