Research and Scholarship
Welcome to the spring 2023 issue of Insight, a newsletter celebrating the accomplishments of our community of scholars. We aim to spotlight insights from people at the Dugoni School working in all areas of scholarship, including clinical or biomedical research, the scholarship of teaching and learning, improvement of the health care system, and professional partnerships that advance the field.
Save the Date for OKU-Sutro Excellence Day!
May 3, 2023 | 1:00 pm- 5:00 pm
1:00 – 2:00 pm | Keynote Presentation — TBD 2:15 – 5:00 pm | Student Presentations/Judging Sessions
Join us as a presenter — or step up and be a judge! Judges will review presentations and posters in dental and basic research, clinical cases, and community health showcase projects prepared by dental students, residents, faculty, and staff.

Research in the Spotlight
Three-dimensional digital applications for implant space planning in orthodontics
What is it?
An overview of 3D imaging tools for implant treatment planning.
What problem does it aim to solve?
Implant failure rates are as high as 20%; good visualization is essential for planning before surgery. “Before, only two-dimensional examinations such as panoramic images were available to clinicians, limiting the capacity of the evaluation to only vertical and horizontal dimensions of the space while evaluating the edentulous area and planning implants.”
How does it work?
Combining multisource images such as Cone-Beam Computed Tomography (CBCT) and 3D digital dental models is essential for proper planning and managing implant surgery combined with orthodontic treatment. In addition, the use of data science approaches, advances in the image analysis field, and new AI approaches are becoming more popular among clinicians because of translational research and software availability. Therefore, better and more personalized treatment can be available, helping the clinical decision making and the prognosis.”
What are the real-world implications?
“The orthodontist needs to analyze each patient individually and use different software or tools that better fit their practice, allowing efficient treatment planning and satisfactory results with an adequate prognosis.”
What are the next steps?
While clinicians can benefit from these tools today, ongoing research alongside the ongoing development of and feature enhancements to these tools will help inform best practices.

Refined Topical 5-Fluorouracil Technique for the Targeted Treatment of Odontogenic Keratocysts
Representative example of odontogenic keratocyst treated with refined topical 5-fluorouracil technique. A, Preoperative Panorex radiograph showing a biopsy-confirmed odontogenic keratocyst involving the right mandibular body, and ramus. B, Six-month postoperative Panorex radiograph showing a well-healed, cystfree right mandible treated with enucleation, peripheral ostectomy, and refined topical 5fluorouracil technique.
What is it?
Odontogenic keratocysts (OKCs) are benign but often aggressive lesions in the jaw. This study represents an investigation of a potentially better way to treat them.
What problem does it aim to solve?
Treatment for OKCs includes application of a drug called 5-fluorouracil (5-FU), which is effective, but the way it is administered, using gauze packing material, is often very uncomfortable/painful for patients, and the gauze may be hard to place correctly if the lesion is too small or in a difficult-to-access location.
How does it work?
Thirteen patients were treated with this new method, in which the surgical cavity was irrigated with saline then covered with topical 5% 5-FU using a cotton swab. The final step was to place absorbable gelatin sponge coated with 5% 5-FU. “This refined technique further increases technical ease, decreases operative time, and precludes the need for packing removal, with similar efficacy as the original approach.

Research and Scholarship
What are the real-world implications?
If results hold up in subsequent studies over time, this method could be a better way of treating OKCs without having to remove packed gauze.
What are the next steps?
“A well-designed, long-term, prospective, randomized, double-blinded, controlled clinical trial would further support the above findings. A prospective study is currently underway.”
