Oral Pathology xray

27-year-old woman referred by her general dentist for evaluation of an incidental finding for a periapical radiolucency . The patient reports to have had a prior RCT on #19 several years prior.

On physical exam the there was no buccal or lingual expansion of the jaw, teeth were not mobile, tooth #20 with lingering cold sensitivity, and area not tender to palpation. 

Panoramic radiograph revealed a well-defined radiolucent lesion extending apically from tooth #21 to #18. The cyst displaced the inferior alveolar nerve inferiorly. The inferior cortex of the mandible is intact, along with no perforation of the buccal and lingual cortices. With IV sedation the patient was prepared for biopsy of the lesion. The biopsy returned as periapical granuloma.

Periapical Granuloma: The most common cyst of the jaw, found at the root apices of involved teeth. Pulpal necrosis with an ensuing infection stimulates the cell rests of Malassez to form a cyst. At times if a tooth is extracted and the apices are not thoroughly curretaged the remaining inflammatory tissue can form a cyst, evolving into a residual cyst.

Differential Diagnosis

  1. Periapical granuloma/radicular cyst
  2. Traumatic bone cyst
  3. Periapical scar

Treatment includes removal of the necrotic pulp either with RC T or extraction and enucleation of tooth. As with this patient extraction of the offending tooth and enucleation of the entire cyst was the modality of the treatment.

What Our Patients Say About Us

Even our patients who have been told in the past that they are not good candidates for dental implants have found options at our clinic.

  • Mindy W.

    This is a very welcoming center. Everyone seemed very competent and helpful. I had an oral biopsy today. No waiting. The staff were ready for me and all was in place. Dr. Yagoubian was warm , cheerful and I felt in extremely capable hands. I am so grateful I was referred to him. Sincerely, Mindy W.

  • Raj G.

    Dr. Yagoubian is excellent. I was in state for business when my wisdom tooth broke. I was lucky enough to find Dr. Yagoubian's office. Everyone there was professional and courteous. The procedure went smoothly. Dr. Y is highly skilled, meticulous, and a very personable health care provider (a rarity in the field, in my opinion). If you need an oral surgeon, I highly recommend him.

  • Chahab S.

    Dr Yagoubian is an excellent oral surgeon, supported by a very professional staff. They made the experience as stress-free as possible. Highly recommended.

  • Paul M.

    A positive experience from start to end. I got a sense that this was going to go well and it did. Two extractions, two implants, bone graft and removal of four part bridge. Leaving part of the bridge on one tooth. If there were 10stars they would be for Torrance oral surgery group and Dr. Alicia Wolf / Blanco Demtal Group for recommending Ben.
