Summary
Periapical cemental dysplasia (PCD) lesions in Japanese patients predominantly occur in premolar-molar regions. This contrasts with PCD lesion locations observed in other ethnic groups, suggesting geographic variations in this condition.
Area of Science:
- Oral pathology
- Dental radiology
- Cemento-osseous lesions
Background:
- Periapical cemental dysplasia (PCD) is a common periapical jaw lesion.
- Understanding the geographic distribution of PCD is crucial for diagnosis.
Observation:
- Three middle-aged female patients with multiple PCD lesions in the maxilla and mandible were analyzed.
- Histological examination revealed fibrous connective tissue and cementum-like hard tissue.
- Lesions were primarily located in the premolar-molar regions.
Findings:
- A literature review of Japanese PCD cases showed a similar predilection for the premolar-molar regions.
- This distribution pattern in Japan differs from that reported in other ethnic groups.
- PCD lesion occurrence sites show ethnic and geographic variations.
Implications:
- The findings suggest that the location of PCD lesions in Japanese individuals is predominantly in the premolar-molar regions.
- This contrasts with the typical anterior jaw location reported in other populations.
- Awareness of these geographic variations can aid in the diagnosis and management of PCD.
