![]() Considering that the use of rubber dam significantly increases the tooth survival rates after initial RCT, its constant usage will improve the infection control―and in consequence the outcome―of endodontic treatment. Moreover, 15% reported that they do not use a rubber dam for any of the RCTs that they provide. A survey conducted in 2013 reported that only 44% of general dentists who perform root canal therapy (RCT) use rubber dam isolation. Although the use of the rubber dam in the United States is considered the standard of care, recent studies have shown that is not universal among general dentists. ![]() Failure to use a rubber dam indicates that the clinician does not understand the need to protect the patient from aspiration or swallowing instruments, the protection afforded the dental staff from contaminated aerosols, the microbial nature of the disease process, and the decreased success rate for treatment when strict asepsis is not used.Įvidence exists that many general dentists unnecessarily place themselves at risk by not using the rubber dam when performing endodontic procedures. Expert testimony is not required in cases involving patients who swallowed or aspirated instruments or materials, because juries are considered competent to determine negligence. Rubber Dam Isolation ApplicationĪpplication of the rubber dam for isolation during endodontic treatment has many distinct advantages and is mandatory for legal considerations. These building blocks are based on the best available evidence and provide a basis for incorporating more complex and alternative techniques. These chapters introduce concepts and principles that are important for successful treatment. A number of instruments and techniques are advocated for treatment procedures. Areas presented include isolation, access, length determination, cleaning and shaping, and obturation. Illustrate the portions of the tooth that must be removed to attain access to the canals.Ĭhapters 14 and 15 address the technical aspects of nonsurgical root canal treatment. Relate reasons and indications for removing caries or restorations before access.ĭescribe the technical procedure, materials used, and sequence to properly access all teeth.ĭemonstrate the step-by-step technique for obtaining estimated and correct working lengths.ĭescribe the practice and accuracy of electronic apex locators. Identify major objectives of endodontic access preparation, including importance of dentin preservation. Identify patients who should be considered for referral. Recognize situations in which special isolation approaches are necessary and identify isolation techniques for unusual situations. After reading this chapter the student should be able to:ĭescribe the rationale for rubber dam isolation during endodontic procedures.ĭescribe techniques for application of the clamp and rubber dam.
