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.
