Speaker Profile

Prof. Ronald Ordinola-Zapata, DDS, MS, PhD

Associate Professor at the Endodontic Division, University of Minnesota School of Dentistry

Dr. Ronald Ordinola Zapata is currently Associate Professor at the Endodontic Division, University of Minnesota School of Dentistry and a Diplomate of the American Board of Endodontics. Dr. Zapata received his master's and doctorate degrees from the University of Sao Paulo in Brazil. He completed his Endodontic residency program at the IB Bender Endodontic Division, Albert Einstein Medical Center in Philadelphia, as well as a Certificate in Clinical Research at the University of Minnesota's School of Public Health. In his academic career, Dr. Zapata has published more than 100 manuscripts in peer-reviewed journals and lectured internationally in more than 16 countries. Dr. Zapata also serves as Associate Editor of the International Endodontic Journal (UK) and is member of the Scientific Advisory Board of the Journal of Endodontics (USA).

Learning content

The removal of bacterial biofilms and their byproducts is critical for apical periodontitis healing. A detailed knowledge of the root canal anatomy, the endodontic microbiome, the periodontal condition, the restorative prognosis and the overall patient’s health should be considered to determine the endodontic prognosis. The disinfection of the root canal system has traditionally been accomplished through mechanical debridement and the application of proteolytic solutions. Specific clinical scenarios have demonstrated that the neutralization of root canal contents can be accomplished only with irrigants and minimal dentin removal. The question of whether the disinfection of the root canal procedure could be achieved with or without enhanced irrigation arises.


In the second part of this presentation, we will address the relationship of the dental pulp and the periodontium. Multiple anatomical and iatrogenic pathways can communicate these tissues in both health and disease. These pathways include furcation canals, dentinal cracks, and vertical root fractures.  In other cases, a cemental root fracture (cemental tear) can mimic periapical pathosis. It is generally agreed that the dental pulp and its necrotic content affect the periodontal tissues. A controversy exists over the ability of periodontal disease to affect the dental pulp.  During this presentation, we will review diagnostic techniques, the prognosis, and treatment alternatives for endo/perio lesions.

Aims and Objectives

This series of lectures will provide participants with a current update on the basic and clinical science of non-surgical root canal treatment. The main goals are:

  1. Highlight the anatomical variations of posterior teeth and its clinical management.

  2. Discuss modern concepts in endodontic microbiology.

  3. Discuss the clinical advantages and limitations of different irrigation solutions and intracanal medicaments.

  4. Discuss the antimicrobial activity of conventional and multisonic irrigation in minimally invasive preparations.

  5. Provide a summary of clinical research that examined the efficacy of various irrigant solutions and intracanal medicaments on apical periodontitis healing.

  6. Evaluate the characteristics and clinical presentation of endo-perio lesions.

  7. Discuss the clinical presentation of cracked teeth, vertical root fractures and cemental tears.

  8. Discuss the endodontic prognosis in cases with complex endo-perio involvement.
