Summary
Enamel pearls (EPs) are rare dental anomalies, often found in molar furcations. This study used micro-CT to analyze EP frequency and morphology, revealing one case mimicking a severe endodontic-periodontic lesion.
Area of Science:
- Dentistry
- Oral Pathology
- Radiology
Background:
- Enamel pearls (EPs) are developmental anomalies, typically found on tooth roots.
- Their occurrence, precise location, and morphological characteristics require detailed investigation using advanced imaging techniques.
- Understanding EPs is crucial for differential diagnosis in complex dental cases.
Observation:
- Micro-computed tomography (µCT) and cone beam computed tomography (CBCT) were employed to analyze EPs.
- 23 EPs were evaluated for frequency, position, number, and morphology.
- A specific case highlighted an EP mimicking an endodontic-periodontic lesion on a maxillary first molar.
Findings:
- EPs were found in 0.74% of the evaluated sample, predominantly in the furcation area of maxillary molars.
- The average major diameter, volume, and surface area of EPs were measured, with no significant differences between maxillary second and third molars.
- The case report confirmed an EP's association with advanced localized periodontitis.
Implications:
- EPs, particularly when located in furcations, can contribute to periodontal breakdown.
- Accurate identification of EPs using advanced imaging is essential for correct diagnosis and treatment planning.
- This study contributes to the understanding of EPs' prevalence and their potential role in periodontal disease etiology.
