The retreatment abilities of ProTaper Next and F6 Skytaper: a micro-computed tomography study.

Eur Oral Res 2021 May;55(2):74-79

Department of Anatomy, Faculty of Medicine, Hacettepe University, Ankara,Turkey.

Purpose: The aim of this study was to evaluate the retreatment abilities of the ProTaper Next (PTN) and F6 SkyTaper (F6) systems by using micro-computed tomography (microct), radiographic and microscopic imaging techniques.

Materials And Methods: The root canals of twenty-six extracted mandibular premolar teeth were prepared and obturated. For the retreatment procedure, the teeth were randomly divided into two equal groups according to endodontic instruments: PTN (X4) and F6 (#40/.06). Pre- and post-operative filling material volumes were measured with micro-ct, and areas were measured with radiographic and microscopic imaging techniques. The percentages of residual material were calculated, and then statistically compared. The significance level was set at p<0.05.

Results: There was no statistically significant difference between F6 and PTN for retreatment efficacy in the micro-ct and radiographic imaging techniques (p>0.05). PTN demonstrated better cleaning ability when evaluated by microscopic imaging. (p<0.05). The correlation was moderate between micro-ct and radiographic, and micro-ct and microscopic imaging groups; however, it was strong between radiographic and microscopic imaging methods.

Conclusion: The PTN and F6 files had similar effects in the removal of filling material with microct evaluation. The radiographic imaging method gave similar results with micro-ct imaging.

Comparison of OneShape, 2Shape and One Curve endodontic instruments for debris and irrigant extrusion.

Dent Med Probl 2020 Jul-Sep;57(3):255-259

Department of Endodontics, Faculty of Dentistry, Gazi University, Ankara, Turkey.

Background: Better understanding is needed about the debris-and-irrigant-extrusion potential of the instruments used for root canal preparation procedures, manufactured of different heat-treated alloys.

Objectives: The aim of the study was to evaluate the single-file nickel-titanium (NiTi) rotary system OneShape® and compare it with 2 different heat-treated instrumentation systems produced by the same manufacturer - a single-file C-wire system (One Curve®) and a multi-file T-wire system (2Shape®) - in terms of debris and irrigant extrusion.

Material And Methods: The mesiobuccal root canals of 51 extracted mandibular molar teeth were selected for the study. The roots were applied to the test apparatus prepared with the Myers and Montgomery method. The roots were divided into 3 groups according to the instrumentation system: OneShape; One Curve; and 2Shape. The root canals were prepared according to the manufacturer's instructions. The analysis of variance (ANOVA) and the post hoc Tukey tests were used to evaluate the significance of the amount of the extruded debris and irrigant (p < 0.05).

Results: The One Curve group produced less debris extrusion than the 2Shape group (p < 0.05). There were no significant differences between the 2Shape and OneShape (p = 0.136), or the One Curve and OneShape groups (p = 0.159). The weight of the extruded irrigant was significantly lower for the One Curve group as compared to other systems (p < 0.05). The mean weight of the extruded irrigant did not differ significantly for the 2Shape and OneShape groups (p = 0.976).

Conclusions: The C-wire One Curve system was associated with less apical irrigant extrusion in comparison with the OneShape and 2Shape systems. The amount of debris extrusion produced by the One Curve system was similar to that produced by the OneShape system and lower than in the case of the 2Shape system.

Evaluation of EDTA, QMix, and Irritrol solutions activated with Er,Cr:YSGG and diode lasers on the push-out bond strength of filling material.

Microsc Res Tech 2021 Apr 12;84(4):584-591. Epub 2020 Oct 12.

Tepebasi Oral and Dental Health Education Hospital, Faculty of Dentistry, Ankara Yıldırım Beyazıt University, Ankara, Turkey.

This study was conducted to evaluate the effects of ethylenediaminetetraacetic acid (EDTA), Irritrol, and QMix solutions used with manual irrigation and diode and erbium, chromium-doped yttrium, scandium, gallium, and garnet (Er,Cr:YSGG) laser activation on the bonding ability of sealer to the intraradicular dentin. The root canals of 90 mandibular incisors were instrumented, and the teeth were allocated randomly to nine groups (n = 10/group) receiving final irrigation with different irrigation solutions (EDTA, Irritrol, and QMix) and irrigant activation techniques (manual, diode laser, and Er,Cr:YSGG laser). Following endodontic filling, three sections of 1-mm thickness were obtained from the middle third of each root. The root filling was subjected to a push-out test to examine the bond strength of the sealer to dentin. The test data were examined using analysis of variance with a significance level of ɑ < .05. Failure modes were determined by stereomicroscopy, and the surface characteristics of dentin were observed by scanning electron microscopy. Irritrol showed less push-out bond strength than did the other solutions in the Er,Cr:YSGG laser groups (p < .05). In the diode laser groups, QMix provided greater adhesion than did Irritrol (p < .05). The activation of QMix with the Er,Cr:YSGG laser increased the bond strength more than did manual irrigation (p < .05). No other significant difference was observed between other comparison pairs (p > .05). QMix provided adhesion superior to that of Irritrol when activated with diode and Er,Cr:YSGG lasers. Er,Cr:YSGG laser activation increased the adhesion of filling material with QMix irrigation.

Comparison of apical debris extrusion using EDDY, passive ultrasonic activation and photon-initiated photoacoustic streaming irrigation activation devices.

Aust Endod J 2020 Dec 3;46(3):400-404. Epub 2020 Sep 3.

Faculty of Dentistry, Department of Endodontics, Konya Necmettin Erbakan University, Konya, Turkey.

The study aimed to determine the effect of different irrigation activation systems on the amount of apical debris extrusion in mandibular molar teeth with curved root canals. Sixty extracted mandibular molar teeth were instrumented with HyFlex EDM system and divided into four groups according to irrigation techniques: passive ultrasonic irrigation (PUI), EDDY, photon-initiated photoacoustic streaming (PIPS) and manual irrigation (MI). After the final irrigation, the extruded irrigants were collected into Eppendorf tubes of known weights. The amount of extruded debris was obtained by subtracting the weight from the initial weight of the tube. The Kruskal-Wallis test was used for statistical analysis. EDDY caused significantly more debris extrusion than the other irrigation activation systems (P < 0.001). PUI caused less apical debris extrusion but there was no statistical difference between PUI, PIPS and MI (P > 0.05). The EDDY activation system was associated with the highest amount of debris extrusion in curved root canals.

Microsc Res Tech 2020 Oct 12;83(10):1290-1296. Epub 2020 Aug 12.

Vocational School of Health Services, Kirikkale University, Kirikkale, Turkey.

This study investigated the effects of fumaric acid on push-out bond strength when applied to dentin surfaces and fiber posts. The root canals of 60 mandibular premolar teeth were instrumented and obturated. After removing two thirds of filling material, teeth were prepared according to six randomized groups (n = 10/group) defined by two fiber post surface treatments (0.7% fumaric acid or 9% hydrofluoric acid) and three dentin conditioning treatments [control (no conditioning); 17% ethylenediamine tetraacetic acid (EDTA); or 0.7% fumaric acid]. After fiber post-cementation, three 1-mm thick discs were obtained from each tooth by transverse sectioning, and each disc underwent push-out bond strength testing. Data were analyzed with a one-way analyses of variance (anova) and t tests; p < .05 was considered statistically significant. Failure modes were determined by stereomicroscopy, and the surface characteristics of dentin and fiber posts were observed by scanning electron microscopy. Push-out bond strength was greater for the group in which the post surface treated with hydrofluoric acid and the dentin surface treated with fumaric acid than the nontreated dentin and hydrofluoric acid-treated post group (p < .05). There were no significant differences between other comparison pairs (p > .05). A combination of fumaric acid dentin conditioning and hydrofluoric acid fiber post treatment strengthened the bonding ability of fiber posts.

Predictive Model of Intraoperative Pain during Endodontic Treatment: Prospective Observational Clinical Study.

J Endod 2016 Jan 12;42(1):36-41. Epub 2015 Nov 12.

Department of Statistics, Middle East Technical University, Ankara, Turkey.

Introduction: This observational study sought to assess the incidence of intraoperative pain (IOP) among patients receiving endodontic treatment and to construct a model for predicting the probability of IOP.

Methods: All patients attending the endodontic training clinic at Gazi University, Ankara, Turkey, during the spring term of 2014 were examined (N = 2785 patients; observation completed in 1435 patients; male: 628, female: 807; mean age: 39 years; 1655 teeth total). Demographic and clinical variables were recorded for patients requiring primary endodontic treatment. Local anesthesia was administered and routine endodontic treatment commenced. After the working length was established, each patient was asked to report any pain according to a visual analog scale. Supplementary local infiltration anesthesia was administered if necessary. If pain continued despite supplementary anesthesia, then the pain score was immediately assessed. A visual analog scale score corresponding to more than mild pain indicated IOP. A predictive model was constructed with multiple logistic regression analysis from the data of 85% of cases, with the remaining 15% of cases being used to test the external validity of the model.

Results: The incidence of IOP was 6.1% (101/1655 cases). One tooth from each patient was randomly selected, with 1435 teeth being retained for further analysis. A multiple logistic regression model was constructed with the variables age, tooth type, arc, pulpal diagnosis, pain present within the previous 24 hours, and anesthetic solution (P < .05). Good fits were obtained for the final model and external control, with a correct classification rate (efficiency) of 0.78, sensitivity (true positive rate) of 0.63, and specificity (true negative rate) of 0.79 for the external control.

Conclusions: A successful predictive model of IOP was constructed with demographic and clinical variables.
