CBCT to Evaluate Internal Root Resorption by Dr. Jason Hales Doctor of Dentistry Posted Tue 28 Dec 2010 1:02am CBCT can be used to evaluate the extent of root resorption. Before this technology, we would have to excavate a resorptive defect to evaluated the extent and restorability. The CBCT allows us to see in all dimensions the extent of a resorptive defect. In this case, the non-restorability was determined with CBCT alone. This saves the patient and ... Read on »
CBCT Reveals Root Resorption Unseen in Regular Radiography by Dr. Jason Hales Doctor of Dentistry Posted Sat 25 Aug 2012 2:40am The following case shows the advantage of CBCT in endodontic diagnosis. The following patient returned to our office today for re-evaluation of #14. We previously looked at #14 which had some gingival swelling, yet we could not definitively diagnose the tooth as necrotic. We assumed the swelling was a periodontal abscess and had given him ...

Resorption of Calcium Hydroxide Paste by Dr. Jason Hales Doctor of Dentistry Posted Fri 03 Apr 2009 11:17pm Calcium Hydroxide is widely used in endodontics for a number of purposes. Its antimicrobial properties are attributed to its high pH (basic), destructive effects on bacterial cell walls and ability to dissolve organic tissue. It is used routinely as an intracanal medicament. It is also used for apexification, apexigenesis, treatment of root resorpt ... Read on »
What is a Root Canal? by Dr. Dean Brandon Posted Tue 14 Jun 2011 6:59pm What is a Root Canal? Sounds bad doesn’t it? Well, where a pulpotomy is the removal of the pulp tissue in the upper chamber of the tooth, a pulpECTOMY (root canal) is the complete removal of all pulpal tissue including down to the end of the roots. Root canals are often needed if a front tooth is traumatized or even knocked out. Yes, we ... Read on »
Dentigerous Cyst by Dr. Jason Hales Doctor of Dentistry Posted Thu 11 Sep 2008 8:49pm This patient was referred to my office for endodontic evaluation. The patient had a prior RCT with some localized, intermittent pain & swelling. My clinical exam revealed #31 normal to percussion, perio defect on distal >14mm. Radigraphs revealed resorption of the distal root, and extensive bone loss on the distal of #31. Due to the s ... Read on »
Calcium Hydroxide as Intercanal Medicament by Dr. Jason Hales Doctor of Dentistry Posted Wed 09 Dec 2009 2:31pm Ca(OH)2 pastes are used in endodontics as a temporary canal filling material for multiple purposes including1. Stimulate continue root development 2. Control exudate/disinfect the canal system 3. Prevention of external root resorption following traumatic injuries 4. Create an apical barrier following over instrumentation Occasionally, I wil ... Read on »
To Scan or Not to Scan? by Dr. Jason Hales Doctor of Dentistry Posted Tue 07 Jun 2011 1:34pm This patient had RCT #2 done about 8 yrs ago in the military. She is reporting pain of several days duration. Today it is percussion sensitive, normal perio probings, no swelling or palpation tenderness. Adjacent teeth are WNL. Radiographs reveal peripical radiolucency and conical shaped root. Two canals have been filled. My assumption ... Read on »
Superstition Springs Endodontics goes 3D by Dr. Jason Hales Doctor of Dentistry Posted Thu 18 Nov 2010 12:14am Superstition Springs Endodontics is excited to introduce cone beam technology (CBCT) into their practice of endodontics. The decision to incorporate this technology has come after a extended review of the technology, research and clinical applications of CBCT in endodontics. Dr. Edward Carlson was among the first endodontists in Arizona ... Read on »
Avoiding Root Canal Therapy with MTA by Dr. Jason Hales Doctor of Dentistry Posted Mon 26 Sep 2011 3:10pm Dr. Hale's excellent post on pulp canal obliteration inspired me to share these few cases where a coronal barrier was also used to avoid root canal therapy. The most recognized reason to avoid complete pulpal debridement is biological, to maintain pulpal vitality, and thus continue root formation, subsequently improving fracture resistance, but t ...

Saving Teeth: Repairing a Resorptive Defect with MTA by Dr. Jason Hales Doctor of Dentistry Posted Thu 27 Oct 2011 12:50pm In 2006, #19 was diagnosed as necrotic pulp w/ acute apical periodontitis. An irregular radiolucency was noted on the mesial aspect of distal root. This was diagnosed a resorptive defect. While some may have elected to remove the tooth and place an implant or bridge, this patient wanted to preserve her tooth, so a root canal and root repair ... Read on »
