![]() Obturation technique choices were lateral/vertical compaction, continuous wave, thermoplasticized injection, carrier-based (gutta percha), thermomechanical compaction with rotary instruments and paste. Sealer preference categories were ZOE, epoxy resin, calcium hydroxide and glass ionomer. Irrigation agents included normal saline, sodium hypochlorite, local anesthetic solution, hydrogen peroxide and chlorhexidine. ![]() Instrumentation preferences were categorized into NiTi hand files, engine-driven NiTi files of any rotary pattern, stainless steel hand files and rotary files of any type. Each had specified categories as well as an ‘other’ category in which practitioners could describe items not listed there were no limits to number of responses allowed. Questionnaire on Endodontic Care PracticesĪfter confirming on the questionnaire itself that the GD was still a GD and that he or she does at least one root canal procedure (RCT) each month, respondents were asked about categories of instrumentation, irrigation, sealer choice, obturation technique, and obturation material. 6 The objectives of the present study were to: (1) quantify GD’s use of specific endodontic materials (types of instrumentation files, irrigation solutions, sealers and fillers) and obturation techniques (2) identify and quantify inappropriate use and (3) ascertain if inappropriate use is associated with dentists’ practice characteristics. 13 Newton and co-workers’ classic long term study showed effects of this material in primates, finding that periapical inflammation predominated whereas the untreated controls showed no inflammation. 8– 12 Use of paraformaldehyde-containing sealers to obturate canals has never been taught in any US dental school. Paste fillers have fallen from favor mostly due to difficulty in controlling the material and inclusion of harmful ingredients. 7 The authors consider single-cone techniques inappropriate, because they may not adequately obturate the canal. ![]() Gutta percha on rigid carriers has recently become popular, with even the earliest studies showing a seal equivalent to conventional gutta percha compacted either with heat or at ambient temperature. Gutta percha has stood the test of time, most often paired with a zinc oxide-eugenol (ZOE) based sealer. 2– 5 Paste fillers are considered inappropriate due to difficulties in controlling placement in canals and because many contain formaldehyde. Single cone techniques lack sufficient research regarding long-term success and therefore are controversial. The authors consider others inappropriate, such as irrigants that are not antimicrobial, since early infections may not be clinically apparent. Some endodontic materials and techniques have significant evidence of effectiveness, and therefore are appropriate for routine use. 1 A limitation of the study was a low response rate, 479 responded (24%). Savani and colleagues surveyed 2000 GDs, finding that most had adopted the more-recent endodontic technologies, such as nickel-titanium (NiTi) rotary instruments and that more-recent graduates were more likely to have adopted newer technologies. Such studies are rare and are generally at a low level of evidence. Only limited evidence is available regarding how general dentists (GDs) have adapted to these changes, such as whether they have adopted newer technologies and maintain endodontic practice consistent with the latest scientific evidence. ![]() The armamentarium available for endodontic treatment continues to evolve and improve, offering clinicians an increasing range of treatment options. ![]()
