Do’s and Don’ts of Endodontic Chlorhexidine Use

 NE OF THE largest causes of endodontic failure is infection. Infection can be the reason for the tooth’s needing endodontics in the first place, or it can be the cause of retreating an already endodontically treated tooth. The causes of infection include caries, fracture, excessive trauma from operative or prosthetic preparation, leakage of restorations, missed canals or anatomy when doing the endodontics initially, inadequate instrumentation of the canal, and calcified canals. Endodontic infections are generally caused by multiple species of bacteria living on the canal walls or in the dentinal tubules.

 HE TOOLS that have advanced the field of endodontics include microscopes, endoscopes, ultrasonic instruments, and the latest addition: Cone Beam Computerized Tomography (CBCT). Traditionally, CBCT has been used by oral surgeons to facilitate implant placement, but now endodontists like us are using it for diagnosis and treatment planning.

E HAVE ALL HEARD a white lie or two—or, for that matter, even told one or two—at some point in our busy lives. “The check is in the mail, I never got the message, I’ll start my diet on Monday,” and even, “That looks so good on you,” are a few good examples. But how about this one? Ever hear the one, “I have never broken an endodontic instrument in a tooth”? Well, show me the dentist who never separated an endodontic file in a tooth and I will show you a practitioner who just doesn’t do a lot of root canals.

HE MORE I LECTURE on alternative methods of endodontic instrumentation compared to rotary NiTi, the more I realize that rotary NiTi is not the issue. The real nemesis for dentists is their continued use of K-files. Rotary NiTi reduces, but does not eliminate, the supposed need for K-files, the instrument of choice for creating the glide path. If one analyzes the design of K-files and the way they are used, one quickly realizes that their design does not support their function. The problem is that very few teachers in most of our schools have ever bothered to make the analysis that is the first step in understanding the relationship between form and function. So let’s give it a try right now.

ALCIUM HYDROXIDE has long been used as an intracanal dressing in endodontics. In the case of procedures that require more than one visit, calcium hydroxide paste remains within the canal space between appointments. As an intracanal medicament, it is stable for long periods, harmless to the body, and bactericidal within a limited area. The benefits of calcium hydroxide treatment are amply demonstrated by its successful results. It is helpful in reducing bacteria not only within the root canal space but also in the periapical tissue. 
ROM 1990 TO 2007, the demand for silver outpaced the supply. In order to balance out the shortage, governments had to inject silver into the market from their strategic stockpiles. The United States government at one time had 6 billion ounces of silver in its stockpile. By 2007, the US government had no silver left in its stockpile. Ninety-five percent of all silver that has been mined for the past 5,000 years has been consumed and is no longer available for use. There are an estimated 1 billion ounces of silver available above ground now.
