    Effects of Intracanal Medicaments on the Measurement Accuracy of Four Apex Locators: An In Vitro Study
    (Galenos Publ House, 2023) Cudal, Hamza; Aslan, Tugrul; Kesim, Bertan
    Objective: This study aimed to examine the effect of various intracanal medicaments on the precision of four electronic apex locators (EALs). Materials and Methods: This study comprised 160 maxillary central incisors. After root canal preparation, a 25-K file was carefully introduced into the root canal until it was perceptible through the apex, and 0.5 mm was subtracted from this amount to determine the actual length. Samples were divided into four groups: calcium hydroxide, double antibiotic paste, triple antibiotic paste, and the control groups. Intracanal medications were removed with EDTA ten days later, and electronic measurements were performed. Chi-square (chi(2)) test was used to assess the precision of EALs within the margins of +/- 0.5 and +/- 1 mm (alpha=0.05). Results: The accuracies of the four EALs did not vary significantly for different intracanal drugs within the bounds of +/- 0.5 and +/- 1 mm (chi(2) tests, p>0.05). Conclusion: The EALs used in this study obtained reliable readings of working length in the context of varying intracanal medications.

    Effects of three different embedding media on the accuracy of different electronic apex locators: An in vitro study
    (Bayrakol Medical Publisher, 2022) Cudal, Hamza; Kesim, Bertan; Aslan, Tugrul
    Aim: In this study, we aimed to evaluate in vitro the measurement accuracy of three electronic apex locators (EALs) in three different embedding media. Material and Methods: Thirty maxillary central incisors were included (N = 30). The specimens were decoronated at cement-enamel junction, and the soft tissues in root canals were removed. The samples were randomly divided into three groups (n = 10). The specimens were embedded in alginate (group A), gelatin (group B) and agar agar (group C), leaving the coronal 2 mm of teeth exposed. Electronic lengths (ELs) of root canals of samples were measured using Raypex 6 (VDW, Munich, Germany), Apex ID (SybronEndo, Glendora, USA) and Ipex 2 (NSK Inc., Kanuma, Japan). In all groups, actual length (AL) values subtracted from EL values, and EL-AL values were recorded. Results: The EL-AL values for each embedding media were classified within an error range of +/- 0.5 mm and +/- 1 mm, and the chi-square (chi 2) test was used to compare the percentage of acceptable measurements of three EALs (alpha = 0.05). The measurements of Raypex 6 in agar agar medium were statistically different compared with those in alginate and gelatin media, within the error margin of +/- 0.5 mm (p < 0.05). Both in alginate and gelatin media, no statistically significant difference was observed in percentages of acceptable measurements with Raypex 6, Apex ID and Ipex 2 within two ranges of error (p > 0.05). Discussion: Within the limitations of this study, alginate and gelatin can be used safely as embedding media in studies investigating the in vitro measurement accuracy of EALs.
