Sickle cell disease

Oral health effects

• Nerve death in healthy-looking teeth (aseptic pulpal necrosis)

  Patients with SCD can develop pulpal necrosis in clinically intact, caries-free teeth with no other odontogenic cause.

  Mechanism: Vaso-occlusive crises in the dental pulp's microcirculation cause ischemic pulp tissue death.

  Clinical management: Consider SCD in the differential for a nonvital tooth with no caries, trauma, or restorative history; manage per standard endodontic protocol.

• Thin or poorly formed enamel (enamel and dentin hypoplasia)

  Developmental enamel (and sometimes dentin) hypoplasia is more common in SCD patients and increases susceptibility to dental caries.

  Mechanism: Chronic anemia and hypoxia during odontogenesis are thought to disrupt normal enamel/dentin formation.

  Clinical management: Reinforce caries-preventive measures (fluoride, sealants, diet counseling) and monitor hypoplastic sites closely.

• Pale or yellow-tinged mouth lining (mucosal pallor / jaundice)

  Pallor of the buccal and labial mucosa and gingiva, sometimes with jaundice, is the most commonly reported intraoral finding in SCD.

  Mechanism: Chronic hemolytic anemia and hyperbilirubinemia.

  Clinical management: Recognize as a diagnostic clue rather than a disease requiring dental intervention; correlate with medical history.

• Jawbone infection and jaw pain (mandibular/maxillary osteomyelitis)

  Documented cases of mandibular osteomyelitis and jaw bone pain occur in SCD, sometimes mimicking odontogenic infection.

  Mechanism: Vaso-occlusion and infarction of jaw bone marrow create ischemic tissue vulnerable to secondary bacterial infection.

  Clinical management: Distinguish bony vaso-occlusive pain from odontogenic infection with imaging/labs before intervening surgically; treat true infection aggressively with antimicrobials.

• Numb lower lip and chin (mental nerve paresthesia)

  Vaso-occlusion within the inferior alveolar/mental nerve canal can cause numbness of the lower lip and chin that may persist for up to roughly 24 months.

  Mechanism: Ischemic injury to the mental/inferior alveolar nerve from vaso-occlusion in the mandibular canal.

  Clinical management: Document baseline lip/chin sensation before invasive mandibular procedures; if new paresthesia arises with no clear procedural cause, consider a sickle-related etiology and involve the patient's hematologist.
