Abstract Introduction The establishment of accurate working length is one of the most critical steps in endodontic therapy from the biomechanical and obturation points of view. Traditionally, the use of radiography and tactile sense methods were used for working length estimation, but recently, the use of electronic apex locator (EAL) has come into existence. The aim was to evaluate the effect of conventional and herbal irrigants on working length determination by Root ZX. Materials and Methods A total of 110 extracted single rooted teeth were taken. Standard access cavities were prepared and samples were randomly divided into 11 groups (n = 10) according to the type of irrigating solutions used. The actual root canal length was measured, and the readings in dry conditions and wet conditions were recorded. The point where Root ZX showed beep was recorded and difference was recorded as well. The recorded data was calculated and statistically analyzed using unpaired t-test. Result In dry conditions, only saline, H2O2, Aloe vera, and green tea gave exact working length using apex locator values. Whereas in wet conditions, only Aloe vera and green tea gave exact working length. Conclusion Although the irrigants and dry conditions influenced the results, Root ZX can be considered to be accurate, and the difference was within the clinically acceptable range and not statistically significant.

The Impact

Abstract Background Radiographic analysis of tooth morphology is mandatory for accurate calibration of the degree of canal curvature angle and radiographic working length to its real dimensions in case difficulty assessment protocols. This study aimed to determine the impact of the degree of root canal curvature angle on maintaining the real working length and the original canal axis of prepared root canals using a reciprocating rotary instrumentation technique. Methods Radiographic image analysis was performed on 60 extracted single-rooted human premolar teeth with a moderate canal curvature (10°–25°) and severe canal curvature (26°–70°). Working length and longitudinal canal axis were determined using cone-beam computed tomography (CBCT) and digital periapical radiography. The real canal length was determined by subtracting 0.5 mm from the actual canal length. Root canals were prepared using the WaveOne Gold reciprocating file (Dentsply Maillefer, Ballaigues, Switzerland). Results There was no significant relation of the degree of canal curvature angle to the accuracy of radiographic working length estimated on CBCT and digital periapical radiographic techniques (P > 0.05). Postinstrumentation changes in the original canal axis between moderate and severe canal curvature angles, assessed on CBCT and periapical digital radiographic images were statistically non-significant (P > 0.05). Conclusions A standardized digital periapical radiographic method performed similarly to the CBCT technique near to its true working length. No significant interaction exists between the diagnostic working length estimation, postoperative root canal axis modification, and the degree of canal curvature angle, using reciprocating rotary instrumentation technique.

Abstract Objectives The aim of the present in vitro study is to compare the remineralization brushing effect of three toothpastes and Aloe vera (AV) gel. Materials and Methods Forty sound extracted teeth were placed in a demineralizing solution for 4 days and randomly assigned to four groups: group A: 1,450-ppm fluoride toothpaste; group B: AV nonfluoridated toothpaste; group C: AV 1,000-ppm fluoridated toothpaste; and group D: AV gel. A 3-minute pH cycling was performed twice a day for each group for 12 days. Specimens were analyzed before and after by scanning electron microscope—energy dispersive X-ray. Statistical analysis The outcomes were analyzed by Kolmogorov–Smirnov’s tests, repeated-measures analyses of variance followed by univariate analyses, and Bonferroni’s multiple comparisons tests to compare the calcium-to-phosphorus (Ca:P) ratio within time among toothpaste groups. Results Following remineralization, the Ca:P ratio increased in all groups. The difference of the Ca:P ratio was not significant between groups C, D, and A. The mean ratio was significantly lower in group B (p-value = 0.026). Conclusions The AV gel demonstrated a remineralization capacity equal to that of the 1,450-ppm fluoride toothpaste. In contrast, fluoride-free AV toothpaste showed a lower remineralization efficiency. Further studies are required to understand its mechanism.

ABSTRACT Introduction This ex vivo study evaluated the accuracy of the Root-ZX electronic apex locator (EAL) (J. Morita, Tokyo, Japan) and the NovApex (Forum Technologies, Rishon Lezion, Israel) in determining the working length (WL) during endodontic treatment. Materials and methods Forty extracted single-rooted human teeth were selected for this study. The actual WL was measured with visual technique by a size #15 k-file under magnification. Then, the canal lengths were measured electronically with both Root-ZX and NovApex apex locators within ±0.5 and ±1 mm. Mean percentage of data was analyzed between groups using paired t-test, with a statistically significant level of p < 0.05. Results The accuracy of NovApex apex locator was 85% within ±0.5 mm and 92.5% within ±1 mm. The accuracy of Root-ZX apex locator was 70% within ±0.5 mm and 97.5% within ±1 mm. There was no significant difference between the accuracy of the two EALs. Conclusion Both the NovApex and Root-ZX EALs are useful for measuring the WL with high accuracy. Clinical significance Given the importance of accurate WL determination in the success of endodontic treatments, the accuracy of different apex locators should be evaluated.

ABSTRACT Aim The purpose of this study was to compare the working length determination done using three methods, namely, apex locator (Foramatron D-10, Parkell), radiovisiography (Planmeca) and conventional radiography (Prostyle intra, Planmeca). Materials and methods In this experiment, to determine the working length, 35 single-rooted teeth were selected and each tooth was subjected to all the three methods of the working length determination. This was compared with the actual working length measured utilizing ground sections of the individual teeth. Results The results revealed that all the three methods located the apex nearly as accurately as the actual root canal length obtained by histological ground sectioning, and among three methods apex locator being the closest to the actual root canal length. Conclusion The study concludes that all the three techniques are equally effective in determining working length. How to cite this article Nanda Kishor KM.

Background: The using of devices that emitted electromagnetic radiation has beenlimited in many healthcare centers to prevent interference with medical devices.The purpose of this in vitro study was to evaluate the effect of Wi-Fi Router(Tenda FH456) on working length determination using electronic apex locator(NSK-iPex II) in the presence of network connection with tablet (GT-N800) ornot.Materials and methods: Twenty-five intact teeth with a single root were sectioned atthe cementoenamel junction. Visually, roots were examined understereomicroscope (X20) and the working length was determined using a size 15K-file. The effect of Tenda Wi-Fi router on accuracy of electronic working lengthmeasurement of electronic apex locator (iPex II) was determined in this study inclosed room under 5 conditions (without router and tablet, with router in differentdistances 1 meter and 3 meters from electronic apex locator, with router andconnected with tablet in different distances 1 meter and 3 meters from electronicapex locator). The electronic working length was measured 3 times per canalunder each condition. The data were compared using analysis of variance.Results: The mean of working length measured under microscope was (13.30), andthe mean of working length by electronic apex locator was (13.14) while the meanvalues of working length in different conditions was fixed (13.12). Analysis ofvariance test (ANOVA) showed non-significant difference among working lengthmeasurements in different conditions (P-value ≥ 0.05).Conclusion: Within the limitations of the present study, stability and reliability ofiPex II apex locator in measurement of electronic working length where notinfluenced when placed in (1M, 3M) from Wi-Fi router and active Tablet(connected to network by Wi-Fi and streaming online videos). During root canaltherapy, active Tablet can be used in the dental operatory without the fear ofcausing electromagnetic interference in electronic working length determination.
