Dr. Obadah Austah is a Consultant Endodontist at AQUA Dent Clinics and Assistant Professor in the Department of Endodontics at King Abdulaziz University's Faculty of Dentistry in Jeddah. He earned his BDS from KAU before completing a full academic track at UT Health San Antonio (UTHSCSA) — a clinical Certificate in Endodontics, a Master of Science in Dental Science, and a PhD in Translational Science focused on pain biology. He is a Diplomate of the American Board of Endodontics.
Dr. Austah's research sits at the intersection of endodontics, neurobiology, and bone immunology. His research, supported by NIH/NIDCR grant R01 DE027929, has investigated how trigeminal afferent neurons regulate apical periodontitis. His work — published in the Journal of Endodontics, Cellular and Molecular Life Sciences, Scientific Reports, and Molecular Pain — has reshaped the understanding of the nociceptor-immune-bone axis in dental infection, and his work on regenerative endodontic procedures in immature teeth is widely cited. He serves on the Scientific Advisory Board of the Journal of Endodontics — the specialty's highest-impact journal.
Clinically, Dr. Austah delivers microsurgical endodontics, non-surgical retreatment, and regenerative procedures for immature permanent teeth — applying evidence from his own bench research directly at chairside.
Apical surgery under the operating microscope — for cases that non-surgical treatment cannot resolve.
Regenerative protocols for immature permanent teeth — preserving pulp vitality and continued root development.
Revising previously failed root canal treatment — with microscopic technique and flexible NiTi instrumentation.
An advanced tooth-preservation option when conventional apical surgery is not feasible — controlled extraction, treatment, and replantation.
Treating teeth with challenging anatomy — accessory canals, severe curvatures, and calcifications — guided by CBCT imaging.
Evidence-based protocols for crown and root fractures, luxation injuries, and avulsion.
Scientific Advisory Board member of the Journal of Endodontics — the specialty's highest-impact journal — with research supported by NIH/NIDCR grant R01 DE027929.
Dr. Obadah Austah is a Consultant Endodontist and member of the Scientific Advisory Board of the Journal of Endodontics (JOE) — the leading peer-reviewed journal in the field.
Using a surgical microscope (4× to 25× magnification) during root canal treatment lets the endodontist see and clean fine accessory canals impossible to detect with the naked eye, materially improving long-term success rates.
Yes — microscope-assisted endodontic re-treatment is a core part of his practice, including post + pin removal and complex apical leakage cases, often saving teeth that would otherwise be extracted.
