About the Department


The Department of Diagnostic Sciences has three divisions: Oral Diagnosis, Oral Pathology, and Oral Radiology, all with their own director and teaching programs.

Pathology is responsible for all teaching of general and oral pathology to dental, dental hygiene and graduate students; provides consultation and biopsy services to the College and the professional community, and has a residency program in Oral and Maxillofacial Pathology.

Radiology is responsible for all imaging programs and through the Imaging Center a service to dental professionals.

Oral Diagnosis combines teaching with patient screening, evaluation and treatment planning for the College as well as a limited care treatment clinic.

Oral Pathology

The Division of Pathology has three full-time faculty members, Dr. John M. Wright, Dr. Harvey P. Kessler and Dr. Yi-Shing Lisa Cheng, and one part-time faculty member, Dr. Aparna Naidu. The faculty provides pathology instruction and patient consultations to dental hygiene, dental and advanced education students. The faculty provides a biopsy service to the college and professional community. The division also has an advanced education program in Oral and Maxillofacial Pathology accredited by the Commission on Dental Accreditation.

Oral Radiology

The Division of Radiology includes the Oral Radiology Clinic in the main building of the dental school and the free-standing Oral & Maxillofacial Imaging Center. There are three attending radiologists, Drs. Byron W. Benson, Hui Liang, and Diane Flint, to provide diagnostic interpretive and consultation services. 

Basic and advanced diagnostic imaging services are provided for regular patients of the dental school as well as patients referred by the professional community for specific imaging studies. The full-service Imaging Center provides services to assist in the management of temporomandibular joint dysfunction, dental implant site assessment, orthodontics, craniofacial anomalies, salivary gland dysfunction, trauma, and general pathology.

Oral Diagnosis

The faculty of the Division of Oral Diagnosis within the Department of Diagnostic Sciences staffs the Oral Diagnosis Clinic and provides the following service and educational functions within the Texas A&M University Baylor College of Dentistry clinical program:

  1. Patients with acute dental problems are screened and directed for treatment as indicated to various clinics of the College such as Oral Surgery, Endodontics, and the Limited Care Clinic. This is essentially the obligation of the faculty with only occasional student involvement.
  2. Prospective patients for comprehensive dental care are screened to determine if the patient’s dental treatment needs can be effectively provided by the various undergraduate and graduate programs of the College. Junior and senior dental students participate in this activity during scheduled rotations.
  3. The diagnostic data collection, diagnosis and preliminary treatment planning of all patients to be treated by third-year dental students in the Comprehensive Care dental program are supervised and reviewed by the faculty in the Oral Diagnosis Clinic.
