    Elba Castro Goguen
    Diplomate, American Board of Endodontics

    The American Association of Endodontists sponsors the American Board of Endodontics. Founded in 1956, the American Board of Endodontics is the only certifying board for the specialty of endodontics and is one of the nine specialty boards recognized by the American Dental Association. The purpose of the ABE is to assure the public that the endodontists it certifies have demonstrated exceptional knowledge, skill, and expertise in the specialty of endodontics and to progressively raise the quality of patient care. Endodontics is focused in root canal treatment and diagnosing and treating tooth pain. Dr. Elba Castro Goguen of Advanced Endodontics of Virginia is the first Loudoun County Diplomate of the American Board of Endodontics. This is the pinnacle of the profession and awards her with the title of Board Certified Endodontist. Becoming a Diplomate of the American Board of Endodontics places the endodontist in a distinguished group of individuals who have demonstrated exceptional knowledge and skill, dedication to continued professional growth, and a commitment to providing the highest quality of patient care. In fact, the practice of endodontics as a recognized specialty of the ADA is reliant upon individuals who achieve Board certification. Approximately only 24% of all endodontists are board-certified. The board certification process involves a written examination, an oral examination, and a case series examination. This is a rigorous process that involves many hours of dedication and commitment and typically takes 3+ years to achieve. Board-certified endodontists have reached the highest level of education in endodontics. They understand and apply new research and literature to the practice of endodontics. They are at the peak of clinical decision-making and treatment planning and have enhanced technique and patient care. They contribute to the reputation and vitality of the endodontic specialty.
