“…These studies differ in establishing the reference point from which measurement accuracy is determined. Some authors measured from the minor diameter (apical constriction) (21,22,(27)(28)(29)(30)(31)(32)(33), whereas others measured from the major diameter or apical foramen (16,23,34). EALs have traditionally afforded some latitude of acceptable error in locating the apex (21,25,26,30).…”

“…Nevertheless, whatever the apical limit, the measuring device used should be precise and reliable (ie, able to locate the chosen limit and giving similar readings when used by more than one operator [37]). The materials most often used are alginate (28,31,32,35,40), agar (36,43), saline solution (24,27), and gelatin (44). The validity of measurements made with in vitro models (ie, the extent to which they depict the clinical accuracy of EALs) is unknown (36).…”

“…Although numerous studies indicate an increase in the accuracy concerning the determination of the WL by different EALs 5,7,[22][23][24] , the fact that prior cervical preparation of root canals performed with different instruments might affect the accuracy of these devices has not yet been proved. Thus, this study was aimed at evaluating the influence of cervical preparation, using LA-Axxess (SybronEndo) and S1 and Sx ProTaper (Dentsply Maillefer), on the accuracy of Root ZX mini and Joypex 5.…”

ObjectiveThis study was aimed at evaluating the influence of cervical preflaring using LA-Axxes No. 1 bur (SybronEndo, Glendora, USA) or S1 and SX ProTaper files (Dentsply Maillefer, Ballaigues, Switzerland) Results McNemar's test (α<0.05) was used to detect differences in the accuracy of the EALs before and after each preflaring with different instruments, and to detect difference in accuracy among devices. No differences were found concerning the accuracy of the EALs (P > 0.05) after the cervical preflaring, regardless of the used instrument. ConclusionThe preflaring procedure increased the number of accurate measurements for both EALs, with statistical difference for Joypex 5 when the preflaring was performed with LA-Axxess. However, after the cervical preflaring, the EALs showed similar accuracy, regardless of the used instrument.Indexing terms: Dental instruments. Endodontics. Odontometry. RESUMO ObjetivoAvaliar a influência do preparo cervical utilizando a broca LA-Axxess nº 1 (SybronEndo, Glendora, EUA) ou os instrumentos ProTaper S1 e SX (Dentsply Maillefer, Ballaigues, Suíça) na precisão dos Localizadores Apicais Eletrônicos (LAEs): Root ZX mini (J. Morita Corporation, Tóquio, Japão) e Joypex 5 (Denjoy, Changsha, China). MétodosTrinta incisivos inferiores foram acessados e o comprimento do canal radicular (CCR) determinado com uma lima K #15 com o auxílio de um estereomicroscópio. Em seguida, os dentes foram distribuídos em dois grupos (n=15) referentes ao preparo cervical com LA-Axxess ou instrumentos ProTaper. Os dentes foram incluídos em alginato e o CCR determinado pelos LAEs antes e após o preparo cervical. Os dados foram classificados em: precisos, se a diferença na medida do CCR era ≤ 0,05 mm; e imprecisos, se a diferença era >0,5 mm ou estava além do CCR.Resultados O teste de McNemar (α<0.05) foi utilizado para detectar diferenças na precisão dos LAEs antes e após o preparo com os diversos instrumentos, e para detectar diferenças na precisão entre os aparelhos. Não foram identificadas diferenças na precisão entre os dois LAEs (P>0,05) após o preparo cervical, indiferente do instrumento utilizado. ConclusãoO preparo cervical aumentou o número de medições precisas dos LAEs, com diferença estatística para Joypex 5 após o uso da LA-Axxess, contudo os aparelhos apresentaram precisão similar após o preparo cervical, indiferente do instrumento utilizado.
