Dr Abiad earned her Bachelor degree in Dental Surgery from BAU where she also pursued, after dental graduation, a one-year program in Advanced General Dentistry and a two-year advanced training program in Fixed Prosthodontics and Restorative Dentistry. After this intensive postgraduate path, she earned a Master’s degree in Endodontics (also from BAU), after which she graduated from Cairo University with a "Doctorate of Dental Sciences - D.D.Sc." degree in Endodontics.

Dr. Abiad is a Specialist Member of the European Society of Endodontology (ESE) and Part of the  European Society of Endodontology Education and Scholarship Committee, engaged in PG programme accreditation. Associate Member of the American Association of Endodontists (AAE) and Active Member and previous vice president of the Lebanese Society of Endodontics (LSE). She has her private practice in Endodontics at Abiad Consulting Clinics ACC. She had many publication in the endodontic education field as well as endodontic microbiology, anatomy, materials and laser Doppler flowmetry.

In terms of basic research, Dr Abiad has actively worked on coronal microleakage, in-vivo LASER Doppler flowmeter measurement, surface cleaning and smear layer removal of root canal walls, bacterial eradication of endodontic canals, treatment of necrotic primary molars, and effect of sonic, passive ultrasonic, and laser energies on root canal dentin walls as well as intraradicular restorative techniques for debilitated teeth rehabilitation, root canal anatomy and root canal instrumentation and obturation as well as retreatment of recently introcuded materials are major parts of her publications. She has also published (in Lebanon , Egypt , Canada, Spain, Australia and United Kingdom) on evaluation of teeth pulp condition, use of laser Doppler flowmeter for detection of tooth vitality, use of CBCT in endodontics, and emergency treatment of pulp and periapical disease and retreatment of endodontic failure, treatment of abnormal root canal anatomy, and clinical efficiency of minocycline. In addition to numerous presentation on students self-assessment methods and effect.
