    Study Notes

    Dental Sclerosis (Condensing Osteitis)

    • A periapical inflammatory condition caused by a localized sclerotic bone reaction to a dental infection.
    • Often linked to a carious or heavily restored, non-vital tooth (sometimes, a vital tooth).
    • Results from infection of periapical tissues in a patient with good immunity and a low-grade inflammatory stimulus.
    • Mostly asymptomatic, with possible mild pain; typically near molar root apices.
    • Affects young to older adults; usually discovered during routine dental X-rays.
    • Radiographic feature: a radiopacity within the periapical area, blending with the surrounding bone, but separated from the periodontal ligament space.
    • Treatment: Removal of the underlying cause (e.g., treatment of the affected tooth); bone lesions often resolve or partially heal.

    Apical Periodontitis

    • A localized acute inflammatory change in the tissues surrounding the tooth's apex, the periodontium.
    • Caused by traumatic occlusion (high spot restorations, rapid orthodontics, bruxism) in a normal pulp or reversible pulpitis, acute pulpitis or pulp necrosis.
    • May present with a history of recent dental work, pain from prior pulpitis, a carious, restored, or discolored tooth.
    • Tooth may be slightly extruded with heavier bite pressure due to inflammatory exudate in the periodontal ligament.
    • Severe, localized pain (even to touch) due to acute nature and triggered periodontal ligament proprioceptors.
    • Pain not elicited by hot or cold stimuli.
    • Pulp tester response varies; no facial edema, alveolar tenderness, or other systemic reactions.
    • Radiographic changes may initially be absent, appearing later as a slightly hazy lamina dura and slight widening of the periodontal space around the apex.
    • Histopathology: a typical acute inflammatory reaction localized to the apex, with engorged blood vessels and an abundance of neutrophils.
    • Treatment:
      • Normal pulp/reversible pulpitis: Remove the irritant.
      • Irreversible pulpitis/pulp necrosis: Root canal treatment.
      • Antibiotics not typically used for acute periodontitis, as direct dental treatment is preferred.

    Periapical Abscess

    • A suppurative condition (pus formation) of the periapical area of a non-vital tooth.
    • Can be acute or chronic.
    • Etiology: Extension of infection from pulp tissue or an acute exacerbation of a periapical granuloma.
    • Pathogenesis: Decayed tooth infection following pulpitis, traumatic injury, or pulp necrosis allows bacterial ingress, causing vasodilation and inflammatory fluid infiltration into the periodontal ligament and alveolar bone.
    • Severe, persisting irritants lead to acute inflammation, neutrophil infiltration, cell necrosis, and pus formation.
    • Acute periapical abscess: Pus stimulates osteoclastic activity and bone resorption, causing submucosal pus extension and swelling.
    • Chronic periapical abscess: Low-intensity irritant or draining pus through a sinus tract; may cause mild pain, discomfort, or a salty taste.
    • Clinical features (acute):
      • Systemic: Acute onset pain, redness, hotness, fever, malaise, lymphadenitis, leukocytosis.
      • Local: Intense, localized pain (periodontal ligament proprioceptors); feeling of fullness, tooth elongation; pain on percussion, non-response to pulp tester (non-vital).
      • Swelling (bone resorption and submucosal pus); possible intraoral or extraoral pointing. Draining leads to chronic stage & pain reduction.
    • Radiographic features:
      • Early: No changes.
      • Progressing: Widening of the periodontal ligament space.
      • Later: Hazy or ill-defined periapical radiolucent area.
      • Chronic: Large, ill-defined periapical radiolucent area.
    • Histopathology:
      • Central pus (necrotic tissue, dead/living neutrophils).
      • Surrounding: Vasodilated blood vessels, dense inflammatory cells (mostly neutrophils), thick fibrous wall.
    • Management:
      • Open access to drain pus through root canal
      • Endodontic treatment.

    Recrudescent (Phoenix) Abscess

    • An acute exacerbation of a chronic periapical lesion (chronic apical periodontitis, chronic abscess, granuloma, or cyst).
    • Etiology/Pathogenesis:
      • Commonly follows root canal treatment; inadequate debridement, untreated necrotic pulp, shift in balance between microorganism virulence and host resistance (high virulence microorganism stimulation or lowered host defense).
      • Sudden worsening of chronic periapical lesion symptoms.
    • Clinical/Radiographic Features: Similar to periapical abscess, except for a large, ill-defined periapical radiolucency.
    • Management:
      • Repeat endodontic treatment or tooth extraction.
      • Antibiotics to control infection spread.
