Analysis of accuracy of endodontic millimeter rulers of different commercial brands
Year: 2012
Type: article
Abstract: ABSTRACT
Objective
Evaluate the accuracy of the Brazilian market of endodontic millimeter rulers.
Methods
The endodontic millimeter rulers were divided into four experimental groups of 10 rulers each, according to the commercial brand: Group 1 - Jon (Comercio de Produtos Odontologicos Ltda., Sao Paulo, Brazil), Group 2 - Microdont (Microusinagem de Precisao Ltda., Socorro, Brazil), Group 3 - Angelus (Angelus Solucoes Odontologicas, Londrina, Brazil) e Group 4 - ICE (Instrumentos Cirurgicos Esmeralda Ltda., Sao Paulo, Brazil). In each endodontic ruler the measure of 20.00 mm was verified with an electronic digital caliper. The results were statistically tested using variance analysis ANOVA followed by Turkey test with p <0.05.
Results
The results showed that the average measures of the rulers are not exact, ranging from 19.80 mm to 20.27 mm for the brand ICE (Instrumentos Cirurgicos Esmeralda Ltda., Sao Paulo, Brazil). The brand Angelus (Angelus Solucoes Odontologicas, Londrina, Brazil) had the lowest variation and exact measurement in 60% of rulers examined. There was no significant difference between brands.
Conclusion
The endodontic millimeter rulers analyzed were not standardized and accurate, so the professional should use the same ruler from the beginning to the end of the treatment.

RESUMO
Objetivo
Avaliar a precisao de reguas endodonticas milimetradas comercializadas no Brasil.
Metodos
As reguas endodonticas milimetradas foram divididas em 4 grupos experimentais de 10 reguas cada, de acordo com a marca comercial: Grupo 1 - Jon (Comercio de Produtos Odontologicos Ltda., Sao Paulo, Brasil), Grupo 2 - Microdont (Microusinagem de Precisao Ltda., Socorro, Brasil), Grupo 3 - Angelus (Angelus Solucoes Odontologicas, Londrina, Brasil) e Grupo 4 - ICE (Instrumentos Cirurgicos Esmeralda Ltda., Sao Paulo, Brasil). Em cada regua foi aferida a medida de 20,00mm por meio de um paquimetro digital eletronico. Os resultados obtidos foram submetidos a analise estatistica utilizando Analise de Variância ANOVA, seguido do teste de Turkey com p<0,05.
Resultados
Os resultados demonstraram que a media das medidas das reguas nao sao exatas, variando desde 19,80mm ate 20,27mm para a marca ICE (Instrumentos Cirurgicos Esmeralda Ltda., Sao Paulo, Brasil). A marca Angelus (Angelus Solucoes Odontologicas, Londrina, Brasil) apresentou a menor variacao e a medida exata em 60% das reguas examinadas. Nao houve diferenca significante entre as marcas.
Conclusao
As reguas endodonticas milimetradas analisadas, nao se mostraram padronizadas e precisas, devendo o profissional utilizar a mesma regua do inicio ao fim do tratamento.
