  • 1. NEWSLETTERS SUMMER 2012 Dentsply Tulsa Dental Specialties Charline Morris Charline.Morris@dentsply.com 416.735.6777 WWW.TULSADENTALSPECIALTIES.COM I’d like to again thank Dr. Ken Serota (kendo@endosolns.com) for his assistance in the preparation of our Summer Newsletters. His expertise and commitment to continuing dental education has been the hallmark of our collaborative efforts going back over nine years.....The material presented is an introduction to a series of courses being prepared for our fall evening study club sessions. Our objective is to ensure that you have continual access to information from both the print and digital worlds to provide you with the ability to deliver the highest calibre endodontic therapeutics possible. Synopsis of newsletters (III) I. History of WaveOne™ Access - think 3D - axial, coronal, sagittal II. Glide Path - secret to NiTi safety ProUltra® Piezo Ultrasonic WaveOne™ system - ProMark™ Endodontic Motor Irrigation - Qmix® (antimicrobial) III. GuttaCore™ Cheers, Charline

If an .04 tapered rotary file is used, then root perforation during post preparation. the GC obturator one apical size smaller is chosen. Advances in materials science and polymer GuttaCore is a notable advancement in endodontics, chemistry enabled the development of a strong core in that polymer chemistry has enabled a core of from a cross-linked, thermoset elastomer of gutta- sufficient strength to be placed in demanding percha that when coated with regular gutta-percha anatomical confines, such as severely curved canals enables the clinician to bypass all the challenges or canals that are difficult to reach. It requires previously associated with the carrier-based minimal heating to be effective in its flow and obturation technique. adaptation to the prepared canal walls. Generally, applications of GuttaCore® (GC) are It should be noted that the the cross linked GC somewhat similar to those used with other GP core obturator is impervious to the use of chemicals for carriers; however, the shaping parameters are softening, although the gutta-percha that surrounds different. The minimum size must be 25/.06 or the obturator is susceptible to softening with greater ideally to ensure optimal canal debridement chemical agents. The goal achievable is the highest and sufficient space and taper for the GC material to level of root canal obturation possible. flow into the canal intricacies. 2
