Biopsy and Consultation Services

OHSU School of Dentistry Biopsy and Consultation Services offer state-of-the-art diagnostic services for all oral and maxillofacial lesions and tumors. Our board-certified pathologists are recognized leaders in the field, providing complete oral histopathologic diagnostic services and clinical oral medicine consultations with referring providers. We gladly offer second opinion consultations and accept patient referrals for thorough examinations and biopsy planning. 

The biopsy service encompasses:

  • Biopsy kits with formalin solution
  • Zeus/Michel's solution can be provided for direct immunofluorescence studies with FedEx Lab Pack and label. 
  • Cytology kits can be provided (typically for the diagnosis of candidiasis or herpes simplex).*
  • Pathological diagnoses faxed or mailed within 24 hours of soft tissue specimen receipt, with exceptions for hard tissue, special stains and DIF studies. 
  • Consultation with pathologist.
  • Most medical insurance carriers accepted.

*While the department does not receive microbiologic specimens for culture, it does receive exfoliative cytology specimens. These specimens are scrapings from the mucosal surface that are then examined under the microscope with special stains. Typically, we suggest that exfoliative cytology be used to diagnose candidiasis and more rarely herpes simplex.

Radiology Services

OHSU School of Dentistry offers craniofacial imaging and other diagnostics, including cone beam computed tomography (CBCT) scans which include a burned CD with CBCT viewer and written radiographic interpretation completed by a board-certified oral and maxillofacial radiologist. We also offer interpretations on your CBCT scans referred to the lab. For your convenience, we provide online HIPPA-compliant uploading of CBCT scans and interpretations. Consultations on images (both 2D and 3D) are also available.
