Web Security: Keep Your Practice Safe From Hackers
Thomas Surgent will be presenting on how to keep your practice safe from hackers.
Topics will include setting up your first password manager. Protecting your email from hackers. Identifying malicious downloads and much more. There will be plenty of time to ask additional questions.
This course is FREE and good for 2 ADA CE Credits. Light food and refreshments will be served.(Continued)
In review of the endodontic failures that come through the office, a great many of them are due to vertical root fractures rather then actual failure of the RCT. This particularly seems to be associated with treatment that uses the aging standard of greater taper. Greater tapered canal preparation of .06 and.04 result in more tooth structure removal hence weakening the root which makes the tooth more susceptible to vertical fracture. As the standard of care is changing to thinner and thinner canal preparation to conserve root structure, the expectation is to see less of an occurrence of fracture over time. The use of rotary or interrupted rotary NiTi is inconsistent with minimal root preparation since it it indiscriminate in both the buccal-lingual and medial-distal dimensions. The use of .02 stainless instruments in a reciprocating hand piece allows targeted instrumentation by internal routing of the canal walls in the buccal-lingual direction while conserving tooth structure in the thinner mesial-distal dimension. Additionally this easily accomplished with NO FEAR of instrument separation.(Continued)
THIS WAS THE YEAR THAT WASN'T
ENDO Tip of the Week - Using an Apex Locator
Using an apex locator! First and foremost, use of an apex locator is the standard of care. It’s a common question and complaint in every malpractice issue I have defended, particularly those involved with overfills and nerve damage to the mandibular canal. So if you have one, please use it. If you don’t have one, please buy one!
It is important to realize that the mechanism by which the apex locator works is the completion of an electrical circuit, lip ground to canal. If one of those contact points is not able to conduct, then there will be a faulty measurement which can lead to over instrumentation or under instrumentation. Thus it is imperative that proper contact is made on the lip ground. A dry lip and lip ground will not conduct well, so wet the lip ground before placement and continually check that the lip is moist under the rubber dam during the procedure. Additionally and equally important, a completely dry canal will be a poor conductor. So it is important to make sure the canal is damp. Using a little RC Prep on the instrument will solve this. A wet pulp chamber, particularly in contact with a metal restoration or tissue will throw the reading off. Don’t use a loose fitting instrument. Use one that has some contact with the canal walls for a more accurate reading. With a little snugness you won’t disturb the position of the instrument as you slide your stop into position. If you are getting close to a measurement of 22 to 25 mm you may want to use a 31 mm instrument so tooth structure or the rubber stop prevent you from getting the instrument clip on firmly. You can also attach the instrument clip to the end of a college plier thus making the plier an extended clip. If you clip it to one end of an explorer it makes a wonderful probe to check for perforations.
A confirmation radiograph can be taken if you feel more comfortable doing so, but I would definitely suggest it if the apicies are in close proximity to the mandibular nerve or any other risky anatomy. Additionally if your locator is not responding in the normal fashion that you are used to, take a confirm radiograph. Calcified apices and debris blocked apicies will also throw off the reading. Hope this is of help. More tips to come!(Continued)
Evolutionary Endodontics: Two Pathways, Different Outcomes - CE Credit
Kase of the Month - Root Amputation Procedure
What would you do if a patient presented with a failing root canal retreatment or a failing apicoectomy?
Dental Root Amputation Procedure
Dental root amputation is described as the surgical removal of one of the roots of a multi-rooted tooth. This procedure is carried out to remove disease, to prevent further bone loss and/or to remove part of the tooth that has a tooth fracture. This procedure is indicated in patients that present with a failing root canal retreatment (RCT) or a failing apicoectomy. This option is worth exploring if a patient wants to save their tooth. Dental root amputation may prolong the viability of a tooth for a few years. Case selection is of utmost importance prior to performing this procedure. Long-term survival rate of a resected tooth is 83% at five years and 68% at ten years. Lower molars usually fail due to root fracture while the upper molars usually fail due to periodontal breakdown progression.(Continued)
Kase of the Month - Never Assume
There are time when assumptions just don't hold water. We all sometimes assume that the anatomy of many roots are written in stone. Maxillary anterior teeth should have only one canal and any irregularities seen on a radiograph are attributed to invaginations in root morphology or artifact, because how could a central, lateral or canine have 2 canals or for that matter 2 roots. We all know that the appearance of an MB2 canal in a maxillary first molar happens 65% of the time. This is not "fake news"! Lower first premolars can easily present with 2 canals. Maxillary second molars can have an MB2 as well. Thus it becomes imperative that we don't accept root or canal morphology as "knee jerk or boiler plate." Angled PA radiographs from both the distal and mesial are helpful. A CBCT scan would be imperative if in doubt. Wouldn't it be nice to know the actual number of canals in a tooth before needless excavation is started and tooth structure is undermined rendering the root more susceptible to fracture. If it is present, then using a scope and conservative excavation is indicated. Don't take it for granted!(Continued)
Kase of the Month - Irrigation is King
In endodontics as with many other things in life there are no shortcuts. Everything that leads to a successful outcome when doing root canal is dependent upon the preceding steps when initiating treatment. Obviously proper diagnosis Is first. To avoid the dentolegal stuff; communication, alternatives, documentation and consent are paramount as well! Cutting to the nitty gritty, when doing root canal if you don't have proper irrigation, the treatment will probably not fall into the success rate of standard endodontics. Debridement is dependent on irrigation, thus If there is not enough irrigation solution in your canal contacting tissue and canal walls the you aren't debriding properly. Whether it's 5.25% sodium hypochlorite, 18% EDTA, or your final irrigation solution of 2% chlorhexidine, all must ultimately get close enough to the apex to do their job. Using 30 gauge needles bent to follow the canal with no wedging and light pressure is key. Delivering solution to the apex is also done with negative pressure irrigation systems where the irrigant is drawn from the pulp chamber to the apex under suction. Most importantly establishing a proper glide path and shape to a patent apex is the key to getting solution to the apical 1/3. Once you start creating your shape and approach a your expected taper the irrigation needle can be placed in a more apical direction. You can't get a 30 gauge needle down a canal that's been instrumented to a 25 with no taper in the proper dimension. That's just math!(Continued)
New Internal Bleaching Solution Making Endo Easier
Dr Amy Dukoff with be presenting at our office on the proper Application of E-Rinse White for Internal Bleaching at our office on October 4th - 6:30PM It removes the dirt & debri & organic material from within the dentin;
- Aids in removing pulpal tissue trapped in the pulpal calcifications.
- Aids in removing the trapped dirt and stains and dead tissue from under the pulpal calcifications
- Facilitates locating the pulpal orifices by removing the unwanted pulpal debri, dirt, stains, tissue in order to improve the illumination - the way light passes through the dentinal tubules- improving visibility inside the tooth.
