The Path to Specialization
Beyond the Operating Microscope
With over 80 peer-reviewed publications and more than 2,500 citations in scientific literature, Dr. Dianat stays actively involved in advancing the field. His research covers a range of topics that directly affect patient care—from developing approaches for calcified canals to improving anesthesia protocols for difficult-to-numb teeth, optimizing how we clean root canal systems, exploring regenerative techniques, and investigating how artificial intelligence might help with diagnosis and treatment planning.
What does this mean for you? When you’re treated by Dr. Dianat, your care reflects not just years of experience, but also current research published in journals like the International Endodontic Journal and Journal of Endodontics.
Teaching and Learning
Dr. Dianat has taught endodontics for many years at SBMU and he currently holds a faculty 
position at the University of Maryland. Teaching has an unexpected benefit: it keeps him sharp.
 Explaining why a technique works forces a deeper understanding than simply performing it.
 Every protocol needs to be evidence-based, every approach defensible.
As a Diplomate of the American Board of Endodontics—a certification held by less than 25% of
endodontists—Dr. Dianat has demonstrated expertise through rigorous examination and case
presentation, a commitment that goes beyond standard licensing requirements.
Innovation in Practice
Dr. Dianat holds two United States patents for innovations in dentistry (US-12336876-B2, 2025 and US-20240398529-A1, 2024). Accurate canal length determination matters—measure too short and infected tissue remains; measure too long and you risk affecting surrounding structures. These patents represent practical solutions developed from treating thousands of patients and looking for ways to improve outcomes.
This approach extends throughout the practice. New technology isn’t adopted for its own sake, but when it offers measurable benefits for patients.
What Matters Most
Outside the Office
When not treating patients, teaching, or researching, Dr. Dianat prioritizes time with family.
His Instagram (@endogram.drd) offers a glimpse into interesting cases and clinical photography for
referring dentists and curious patients alike.
Clinical Expertise
Caring for Anxious Patients
Many patients arrive at an endodontist’s office already nervous, sometimes after putting off care for months or even years. Dr. Mansouri has developed a reputation for helping these patients feel at ease. Her approach combines thorough communication before treatment with comfort techniques refined over years of practice. The result? Patients often describe their root canal experience with Dr. Mansouri as more comfortable than routine fillings they’ve had elsewhere.
This doesn’t happen by accident. It comes from genuine care, technical skill, and the patience to meet each person where they are.
