MEET DR. GARRETT GUESS


 

 

Dr. Guess is a La Jolla native, and obtained his specialty training at the Department of Endodontics at the University of Pennsylvania, where he received the Louis I. Grossman Award as the top endodontic resident. He attended the University of the Pacific School of Dentistry where he obtained his DDS degree as valedictorian of his class.

 


Dr. Guess is Board Certified as a Diplomate of the American Board of Endodontics which represents Dr. Guess’ ongoing dedication to possessing the highest level of clinical skill and updated scientific knowledge to provide the best possible evidence-based care to his patients.  Becoming Board Certified is a process that starts with first being Educationally Qualified by attending and completing an accredited Endodontic Speciality program.  Next, the level of Board Eligible means an application has been submitted to commence the Certification process, and then finally the level of Board Certification is obtained by succeeding with the 3-part examination process: written exam, case presentation and an oral examination process.  Less than 1/4 of practicing endodontists successfully complete the process and obtain the level of Board Certification which represents the pinnacle in educational and clinical capabilities in the specialty of Endodontics.  Board Certification is not only about having the skill and knowledge to pass the exams at the time of certification, but it is a commitment to the specialty and to patients to stay on top of the advancements in endodontics due to the 10 year recertification cycle that is required of all Diplomates like Dr. Guess that became Board Eligible after 1996.


Training from the University of Pennsylvania has given Dr. Guess the tools, experience and knowledge to treat all types of endodontic cases both conventionally and surgically. Dr. Guess has shared these abilities by instructing at the bimonthly microendodontic and microsurgical continuing education courses at the University of Pennsylvania Center for Micro-Endodontics and he is currently an adjunct assistant professor at the University of Pennsylvania Department of Endodontics.  For two years was on teaching staff for the General Practice Residency program at the Veterans Administration Heathcare System, San Diego, in La Jolla, CA.

Dr. Guess is active in the San Diego County Dental Society, having served for two years as the Chairman of the New Dentist Committee which organized events for dentists in practice less than ten years. For 10 years he has been on the Editorial Board for the Dental Society's newsletter Facets and is the publication's Technology Editor, contributing monthly articles and editorials to the Facets newsletter on topics ranging from endodontics to technology and its use in dentistry. For 10 years Dr. Guess served on the Specialist Advisory Board as the sole endodontic advisor for the San Diego Advanced Study Group and provided CE lectures to the club about the most recent advances in microscopic endodontics. He is also a specialist member of other study clubs in the San Diego County providing Continuing Education lectures, and has been a regular speaker for a local Continuing Educational Group Lecture Series providing CE lectures to local dentists on endodontic advancements.  Dr. Guess was a featured speaker at the University of Pennsylvania's 125th Anniversary Symposia Series entitled "Impact of High-Technology on Modern Clinical Dentistry" held in May, 2003 in Philadelphia, Pennsylvania. The continuing-education lecture topic for dentists and specialists covered technologic advancements in dentistry: their uses, benefits, and methods of incorporation in the advanced dental office in the information age.  He is a Specialist member of the American Association of Endodontists, American Dental Association, and California Dental Association and has been voted as a “Top Doctor” in San Diego Magazine’s annual review as voted by his peer dentists for the past eight years in a row.  He presented two sessions at the 2009 American Association of Endodontists annual session: one on surgical endodontics, and another on implant surgery in the endodontic practice.  At the 2010 Association Annual Session in San Diego, he gave three different lecture sessions, which included performing an endodontic microsurgery live-patient demonstration in front of the entire convention audience.  The titles of the sessions were: Elevating the Bar in Microsurgery: From Success to Service; Microsurgery and Grafting with a live patient demonstration; and finally Microsurgery A-Z: Theory and Practice.  At the 2011 Annual Session, Dr. Guess presented a surgical lecture with standing room only to his colleagues entitled Managing the Challenges of Endodontic Microsurgery.  In September 2012 he was part of an expert panel on surgical endodontics at the 2012 American Association of Oral and Maxillofacial Surgeon’s meeting held in San Diego. As part of the University of Pennsylvania Global Endodontic Symposium on Retreatment Surgical/Nonsurgical Management in November 2014, Dr. Guess presented to his colleagues on grafting in endodontic microsurgery.  And in November 2015, Dr. Guess presented about the exciting CBCT imaging impact on endodontic treatment planning at the “Penn Endo Global Symposium México 2015” event in Mexico City. Dr. Guess was an invited speaker at the 2017 American Association of Endodontists Annual Meeting and presented three sessions covering topics on surgical endodontic principles and 3-dimensional CBCT imaging.

Dr. Guess has been active in endodontic research, starting in August 2003 he published his own research in the peer reviewed Journal of Endodontics entitled, "Analysis of Continuous-Wave Obturation Using a Single-cone and Hybrid Technique." This project tested and proved the effectiveness of the most popular and effective root canal filling technique used by Dr. Guess and clinicians around the world. Dr. Guess presented this research topic and the findings in a lecture at the American Association of Endodontists annual meeting in 2001. Dr. Guess is also a featured author in the 2004 edition of the Dental Clinics of North America text book. Dr. Guess authored a chapter entitled, "Modern Dental Office Design in the Information Age" which reviews the methods and issues involved in setting up an endodontic practice using the most advanced offerings that technology has available today with Dr. Guess' own practice design serving as the model for this chapter. In 2004 Dr. Guess published an article in the Journal of Endodontics with a clinical aid article discussing his root canal retreatment technique entitled, "Predictable Therma-fil removal technique using the System-B heatsource," which was accepted and published in the January 2004 Journal of Endodontics issue. This article shares Dr. Guess' technique with his fellow endodontic colleagues to assist in the difficult retreatment of endodontic cases filled with Therma-fil obturators. Dr. Guess’s surgical case was used as an example of the capabilities of the recent technology and techniques in surgical endodontics in the July 2006 Journal of Endodontics cover article entitled “Modern Endodontic Surgery Concepts and Practice: A Review.”  His case was also the focus of the November 2008 international publication entitled “Einzelzahnimplantat oder Zahnerhaltung durch nicht-chirurgische Endodontie - Was ist die richtige Lösung?” in the German dental journal Aesthetische Zahnmedizin.  With his colleagues from the University of Pennsylvania, he contributed and authored the March 2007 Journal of Endodontics study titled "Microscopic Periradicular Surgery: Perioperative Predictors for Postoperative Clinical Outcomes and Quality of Life Assessment" which described and studied the common postoperative findings associated with contemporary apical surgery procedures.  Dr. Guess authored the article “An alternative to gutta-percha for root canal obturation” which was published in Dentistry Today in the December 2008 issue which reviewed a new root filling material available in endodontics.  And in 2010, Dr. Guess and two of his fellow faculty members from the University of Pennsylvania Department of Endodontics published the newsletter, Endodontics: Colleagues for Excellence Fall Edition titled “Contemporary Endodontic Microsurgery: Procedural Advancements and Treatment Planning Considerations.”  This publication was sent to every endodontist and every practicing dentist in the U.S. by the American Association of Endodontists to elevate their understanding on the status and capabilities of contemporary endodontic microsurgery and how it can benefit their patients.  Dr. Guess is currently working with his colleagues on producing the second textbook edition of the Atlas of Endodontic Microsurgery.

Over the past 16 years, Dr. Guess developed and designed the clinical computer system used in his office to better treat his patients and communicate with his referrals. His system is also installed at the University of Pennsylvania to maximize computerization of clinical research projects and is used by other endodontist offices across the nation, Europe, Canada and Australia. The system is called EndoTrak, and is a comprehensive endodontic practice management software solution. With the advanced computerized system managing information in the practice, all charting and patient information is efficiently and securely managed to provide comprehensive and efficient care to patients. The program Dr. Guess created was first introduced to endodontists at the American Association of Endodontists Annual Meeting in Tampa, Florida. In 2001, the research-oriented version of the software program developed for U. Penn was presented by Dr. Guess to the American Association of Endodontists annual meeting in Chicago, where it was awarded a research grant from the AAE Foundation. Also, Dr. Guess' additional technology work at the University of Pennsylvania was featured by Apple Computer on their web site which highlighted his work to streamline the surgical documentation process still utilized by the University of Pennsylvania’s Department of Endodontics, and in Dr. Guess' own office.
