The Journey to Excellence
Beyond the Operating Microscope
With over 80 peer-reviewed publications and more than 2,500 citations in scientific literature, Dr. Dianat isn’t just practicing endodontics, he’s actively shaping it. His research spans the spectrum of endodontic challenges:
Guided Endodontics: Developing techniques to navigate calcified canals that others deem “untreatable” Anesthesia Protocols: Solving the puzzle of why some teeth won’t get numb and how to overcome it Irrigation Dynamics: Optimizing bacterial elimination in complex canal systems Regenerative Techniques: Pushing the boundaries of pulp regeneration in mature teeth Artificial Intelligence Applications: Pioneering AI integration in endodontic diagnosis and treatment planning
When you’re treated by Dr. Dianat, you’re benefiting from techniques that were often published just months ago in journals like the International Endodontic Journal and Journal of Endodontics. Your treatment incorporates methods that other endodontists are just beginning to learn.
The Teacher Who Practices
Dr. Dianat maintains faculty positions at both the University of Maryland and the University of Southern California, where he teaches endodontic residents the same techniques he uses daily. This dual role keeps him at the forefront of the field. Teaching forces him to articulate not just what works, but why it works. It demands that every technique be evidence-based, every protocol defensible, every outcome measurable.
His involvement with the American Association of Endodontists goes beyond membership. As a Diplomate of the American Board of Endodontics, he’s demonstrated the highest level of expertise through rigorous examination and case presentation. This certification, held by less than 25% of endodontists, reflects a commitment to excellence that goes beyond state licensing requirements.
The Patents and Innovation
Dr. Dianat holds two United States patents for endodontic innovations that address one of the most critical aspects of root canal therapy: precise measurement of canal length. His patents, “Apparatus for measuring the length of root canal and a method of use thereof” (US-12336876-B2, 2025 and US-20240398529-A1, 2024), represent practical solutions to a challenge every endodontist faces daily.
Accurate canal length determination is the difference between successful treatment and complications. Too short, and infected tissue remains. Too long, and you risk damaging surrounding structures. Dr. Dianat didn’t just identify this problem; he invented a solution now recognized by the U.S. Patent Office. These aren’t theoretical concepts sitting in a drawer, they’re innovations born from treating thousands of patients and refusing to accept the limitations of existing technology.
When existing tools weren’t adequate, he didn’t just work around limitations, he invented solutions. This innovation mindset permeates his practice, where adopting new technology isn’t about having the latest gadget, but about achieving better outcomes.
A Personal Approach to Specialized Care
Despite his academic achievements, Dr. Dianat’s greatest satisfaction comes from the simple act of relieving pain and saving teeth. He personally reviews every case before treatment, during the procedure, and at follow-up. He’s known for calling patients the evening after treatment to check on their recovery, a practice he’s maintained since his residency days.
“Research and teaching make me a better clinician,” Dr. Dianat explains, “but it’s the patient in my chair who matters most. Every published paper, every lecture, every new technique ultimately serves one purpose: giving that patient the best possible outcome.”
Outside the Office
When not in the office, teaching, or researching, Dr. Dianat prioritizes family time. He believes that balance in life translates to steadiness in practice. His Instagram (@endogram.drd) showcases interesting cases and clinical photography, offering referring dentists and curious patients a window into the microscopic world of endodontics.
Why It Matters
Choosing Dr. Dianat means choosing someone who:

Always thirsting for knowledge, Dr. Mansouri keeps up-to-date with the latest advancements in dentistry, endodontics, radiology, and sterilization. She has always gone beyond what is expected to offer only the best to her patients.
Dr. Mansouri’s approach to your treatment always starts with patiently listening to you. Then, after a complete and thorough examination, she reviews and discusses the diagnosis and treatment options with you. She is honest with her patients and she will always give time to her patients to ask questions.
Why It Matters
Dr. Mansouri brings a patient-first philosophy to endodontics, believing that exceptional clinical care begins with exceptional communication. She takes time to ensure patients understand their condition, their options, and the reasoning behind her recommendations, often drawing diagrams and showing radiographs until anxiety is replaced with understanding.
Clinical Excellence
Dr. Mansouri stays at the forefront of endodontic advancement through continuous education in contemporary techniques, CBCT imaging, regenerative procedures, and advanced pain management. She’s one of the few endodontists in Orange County certified in NightLase therapy, a non-invasive laser treatment that reduces snoring by tightening oral tissues.
Approach to Care
Known for successfully treating patients with severe dental anxiety, Dr. Mansouri combines thorough pre-treatment communication with proven comfort protocols. She maintains close collaboration with referring dentists through comprehensive reports and remains available for consultation on complex cases.
Patients consistently describe their root canal experience with Dr. Mansouri as more comfortable than routine fillings elsewhere. This isn’t coincidence, it’s the result of deliberate techniques refined over years of practice, where technical precision meets genuine compassion.
We look forward to helping you schedule with us and experience the best quality, affordability, comfort, and care.
