Summary
A rare implant periapical lesion (IPL) was caused by starch particles from surgical gloves. Treatment involved debridement and implant resection, suggesting a less invasive approach for managing such foreign-body reactions.
Area of Science:
- Dentistry
- Oral Surgery
- Pathology
Background:
- Implant periapical lesions (IPLs) can arise from various causes.
- Identifying the etiology of IPLs is crucial for effective management.
- Stable dental implants can still develop periapical pathologies.
Observation:
- An osteolytic lesion was observed around a stable Straumann hollow-screw implant 3.5 years post-placement.
- Radiographic findings indicated bone loss around the implant apex and mid-portion.
- Histopathology revealed chronic inflammation and foreign-body material.
Findings:
- Foreign-body material was identified as starch particles using polarized light microscopy and Fourier transform infrared microspectroscopy.
- The etiology of the implant periapical lesion was attributed to a foreign-body reaction to starch.
- Starch contamination likely originated from starch-coated surgical gloves during the implant procedure.
Implications:
- This case highlights an unreported etiology for implant periapical lesions.
- IPLs caused by foreign-body reactions may be managed by debridement and implant resection, avoiding complete implant removal.
- Systematic histopathologic examination of peri-implant soft tissue is recommended for accurate diagnosis.
