Acute Apical Periodontitis : Histology

Acute Apical Periodontitis : Histology A. The apical region of the root canal pulp is infiltrated by inflammatory cells; the toxins that are released during the inflammatory process elicit the periapical inflammatory reaction. B. Coronally one observes necrotic tissue, but further apically the tissue contains only individual inflammatory cells. The cavitation and apparent dissolution of […]

Internal Mineralization: Histology

Internal Mineralization: Histology Histology A. Fibrodenticle in the process of increasing adherence to the root canal wall by means of active secondary dentin formation. B. Denticle attachment to the canal wall in secondary dentin (the cleft is an artifact). C. Onion skin-shaped, irregularly formed fibrodenticle. D. Free fibrodentin denticle with hard tissue forming pulpoblasts at […]

Open Pulpitis: Histology

Open Pulpitis: Histology

Open Pulpitis: Histology Histology A. The carious process has destroyed much of the dentin, and bacteria have entered the pulp chamber; the result is ulceration as well as a massive accumulation of inflammatory cells. From the ulcerative pulpal tissue, granulation tissue begins to emerge and literally grow out of the coronal opening. The bacterial infiltration […]

Irreversible Pulpitis : Histology

Irreversible Pulpitis : Histology

Irreversible Pulpitis : Histology Histology The advanced dentin caries beneath the fissure has reached the pulpal tissues; note the accumulation of inflammatory cells. The root canal pulp exhibits several diffuse calcifications, but is inflammation-free. Within the coronal pulp, one notes a massive inflammatory cell infiltration with small areas of tissue disintegration. The bacteria within the […]

Reversible Pulpitis: Histology

Reversible Pulpitis: Histology

Reversible Pulpitis: Histology Histology Secondary (repair) dentin and denticle formation adjacent to the advanced dentin caries. Secondary dentin has only few tubules and is bordered by few odontoblasts. Within the pulp horn, one notes an accumulation of inflammatory cells. Note the initial disintegration of the odontoblastic layer and the obvious inflammatory cell infiltration, without tissue […]

Dental Caries : Histology

Dental Caries : Histology Histology Fig – A/B : Penetrating advanced dentin caries, with carious opening into the pulpal tissue and adjacent necrosis. Fig – C/D : Dilation of the dentinal tubules as ampullae and garlands (zones 1–3). Fig – E/F :  Bacterial expansion of dentinal tubules. Fig – G  : Bacteria can also penetrate […]
