Multiple internal resorption in permanent teeth associated with hyperparathyroidism

Area of Science:

• Dentistry
• Endodontics
• Oral Pathology

Background:

• Internal resorption is a dental defect where pulp tissue transforms, leading to dentin resorption.
• While often idiopathic, factors like trauma and caries can contribute; typically affecting single teeth.
• External root resorption is commonly linked to systemic conditions like renal disease and hyperparathyroidism.

Observation:

• A 28-year-old female presented with fractured permanent teeth and multiple internal resorptions.
• Resorptions affected incisors, canines, and premolars, sparing molars.
• Elevated parathyroid hormone (PTH) and uric acid levels were noted.

Findings:

• This case presents a rare association between multiple internal root resorptions and hyperparathyroidism.
• The patient's elevated PTH and uric acid levels suggest a potential systemic etiology for the widespread internal resorption.
• This contrasts with the more common association of external root resorption with systemic disorders.

Implications:

• This case suggests hyperparathyroidism may be a contributing factor to multiple internal root resorptions.
• Further research is needed to explore the link between systemic metabolic disorders and internal resorption.
• Understanding these associations can improve diagnosis and management of complex dental cases.
