Comparison of Romidan RomiApex A-15 & J Morita Root ZX<\/h2>\n
SUMMARY<\/div>\n
The purpose of this study was to determine the capacity of the studied equipments to locate the foramen exit position correctly,\u00a0fundamental data for working length determination. Twenty extracted superior central incisors, totaling twenty canals, were used in this\u00a0experiment. Measurements were executed at the point \u201c0.5\u201d of the new Romiapex A-15 apex locator unit (Romidan, Israel) and at the\u00a0second green mark indication of the Root ZX II (J. Morita, USA) apex locator unit. Once obtained the electronic reading, the file used as\u00a0electrode was fixed in position. The gauging of the results was accomplished by wearing one of the external radicular walls of the root\u00a0apical third, and direct visualization with aid of a surgical microscope. The results indicated that, on average, Romiapex A-15 indicated\u00a0measures 0,24mm (\u00b10,30) short of the exit of the apical foramen, and Root ZX II 0,21mm(\u00b10,25), not presenting significant differences\u00a0between the two devices. The analysis of the results indicated that all measurements were inside of an acceptable clinical limit,\u00a0demonstrating that the tested devices are precise and reliable in the determination of the foramen exit position.<\/div>\n

INTRODUCTION<\/div>\n
The establishment of the correct apical limit of instrumentation is accepted as one of the most important operative procedures in\u00a0Endodontics. Significant evidences show that the instrumentation until the limit of the radiographic apex or above and beyond this, it can\u00a0commit in a irreversible way the success of the clinical endodontic therapy.\u00a0Although the main radicular canal is limited for the apical foramen, also known as larger foramen, the point of smaller diameter of this\u00a0canal is found usually in the apical constriction, equally call of smaller foramen, being located, on average, approximately 1mm short of\u00a0the apical foramen, being able to, still, to vary its position from zero to 2mm short of the foramen. This point contains the pulpal tissue,\u00a0communicating it to the apical periodontal ligament. The operative procedures in Endodontics should be contained in such limit that\u00a0doesn’t cause damages to the periapical tissue, favoring the cure and repairing of this area after the treatment. It is accepted that the\u00a0apical constriction should be the ideal limit of instrumentation and filling.\u00a0Some techniques of determination of the endodontic working length were described and checked scientifically, among them the digital\u00a0tactile sensibility, methods based in radiographic analysis, and electronic methods. The third generation of apex locators (APIT, ENDEX,\u00a0APEX FINDER, JUSTY II, ROOT ZX and ROOT ZX II, BINGO 1020, NOVAPEX, among others), were checked in past studies and in vitro comparison of two electronic apex locators\u00a0indicated reliable and precise measurements of the position of apical foramen. The presented positive results were shown superiors to those\u00a0of the INGLE radiographic technique. The present study intends to identify if the new Romiapex A-15 and Root ZX II present necessary\u00a0and reliable measurements for the position of the foramen, indispensable point in the calculation of the working length.<\/div>\n

CONCLUSION: Considering the results of this study, it can be concluded that new Romiapex A-15 and Root ZX II presented precise and reliable\u00a0measurements in the executed experimental conditions, being shown efficient in the determination of the foramen exit position at clinical\u00a0limits.<\/div>\n<\/blockquote>\n
