Summary
This case study highlights external root resorption in a mandibular molar, distinct from typical periodontitis-related furcation defects. Careful diagnosis is key to differentiating these conditions.
Area of Science:
- Dentistry
- Periodontology
- Oral Surgery
Background:
- A 51-year-old female presented with a suspected complicated furcation defect on a mandibular right second molar.
- Clinical examination revealed a lesion near the furcation entrance, with periapical radiographs showing root and periapical radiolucency.
Observation:
- Radiographs showed a root lesion overlapping the furcation and periapical radiolucency.
- A large concave lesion was noted close to, but not directly connected to, the furcation.
Findings:
- Exploratory surgery revealed a deep, round lesion and a complete vertical root fracture after amalgam restoration removal.
- The diagnosis shifted to tooth fracture with external root resorption.
Implications:
- External root resorption can occur in the furcation area due to chronic inflammation, presenting differently than periodontitis.
- Differentiating root resorption from periodontitis-induced furcation involvement requires careful clinical and radiographic interpretation.
