Summary

Pseudohypoparathyroidism, a genetic disorder, presents with Albright hereditary osteodystrophy and numerous dental anomalies. Early dental signs can delay diagnosis of this condition.

Area of Science:

  • Endocrinology
  • Genetics
  • Dentistry

Background:

  • Pseudohypoparathyroidism (PHP) is a rare genetic disorder characterized by resistance to parathyroid hormone.
  • Albright hereditary osteodystrophy (AHO) is the common phenotype associated with PHP, featuring distinct physical characteristics.
  • Dental anomalies are recognized manifestations of PHP, though often not the primary diagnostic focus.

Observation:

  • A case of pseudohypoparathyroidism is presented with classic Albright hereditary osteodystrophy features: short stature, round face, brachydactyly, and soft tissue calcifications.
  • The patient exhibited significant dental anomalies, including enamel hypoplasia, hypodontia, malformed roots, enlarged pulp chambers, microdontia, and pulp calcifications.
  • Additional unique findings in this case were ankylosis and an enlarged frontal sinus.

Findings:

  • The study highlights the diverse dental manifestations associated with pseudohypoparathyroidism, extending beyond previously reported findings.
  • The presence of ankylosis and an enlarged frontal sinus are noted as additional clinical observations in this specific case.
  • A significant delay in diagnosing pseudohypoparathyroidism was observed, attributed to the early and prominent presentation of multiple dental anomalies.

Implications:

  • Early recognition of dental anomalies in children may prompt earlier investigation for underlying conditions like pseudohypoparathyroidism.
  • Understanding the full spectrum of dental manifestations can improve diagnostic accuracy and timely intervention for PHP.
  • This case underscores the importance of a multidisciplinary approach involving endocrinologists and dentists for comprehensive patient care.
