Seventeen human maxillary molars with vital pulp were scheduled for an extraction and implant placement as part of a periodontal treatment plan. The access cavity was prepared, and a #10 K file (Dentsply Maillefer, Ballaigues, Switzerland) was inserted into the palatal root using the Root ZX apex locator in order to determine the electronic working length (EWL); then, the teeth were extracted.

Materials and Methods: 24 maxillary incisors with history of trauma and PCO were included. Pre- operative CBCT WL measurements were performed using the softwares. Five EALs according to manufacturer’s instructions, followed by the radiographic method. Results: Pre-operative CBCT measurements (n=16) were similar among the different software (P>.05).

To achieve this objective the apical constriction must be detected accurately during canal preparation and precise control over working length during the procedure must be maintained. There are many methods of working length determination including electronic method. Introduction of apex locators have definitely served as an effective adjuvant to radiographs.

  • The Standard of Practice in Contemporary Endodontics
    ENDODONTICS Colleagues for Excellence Fall 2014 The Standard of Practice in Contemporary Endodontics Published for the Dental Professional Community by the American Association of Endodontists and the AAE Foundation www.aae.org/colleagues Cover artwork: Rusty Jones, MediVisuals, Inc. ENDODONTICS: Colleagues for Excellence s we approach the third decade of our advancing millennium, one of the realities of American dentistry is the expanding A shift in the delivery of patient care. The private practice model is shrinking and giving way to corporate and group models promoting interdisciplinary treatment planning. This shift promises competence, reliability and cost control, all demanded by the corporate and industry structures that deliver the care (1). As dental schools graduate novice practitioners trained and educated in a “generalist model” of care, many young practitioners will seek opportunities within these groups that provide patient services involving more and more complex endodontic procedures under an interdisciplinary umbrella. Thus, it is increasingly important for the generalist and the specialist to participate in concerted patient management with the overriding value of quality and patient safety at its core (2). A sustainable practice model that promotes high-quality, collaborative treatment has been a hallmark of American dentistry for decades, and newer practice models must maintain this high standard in order to provide value for patients and manage the complex dental problems that will regularly arise. The practice of endodontics has concurrently experienced a shift in the delivery of services and the advancement of scientific discovery within the field. Emergent technologies in instrumentation, magnification and imaging aimed at treating and salvaging the natural dentition with consistent outcomes, are all hallmarks of contemporary endodontic practice.
