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.
