Publication Metadata only Comparison of Apical Extrusion of Sodium Hypochlorite Using 4 Different Root Canal Irrigation Techniques(ELSEVIER SCIENCE INC, 2015) TARÇIN, BİLGE; Iriboz, Emre; Bayraktar, Koral; Turkaydin, Dilek; Tarcin, BilgeIntroduction: We compared the apical extrusion of sodium hypochlorite delivered with a 27-G needle, self-adjusting file (SAF), passive ultrasonic irrigation, or the Endo Vac system (SybronEndo, Orange, CA) during the instrumentation and final irrigation of root canals. Methods: Matched paired single-canal teeth were divided into 8 groups. The experimental groups were needle irrigation size #30 (NI30) and #50 (NI50), SAF size #30 (SAF30) and #50 (SAF50), passive ultrasonic irrigation size #30 (PUI30) and #50 (PUI50), and Endo Vac size #30 (EV30) and #50 (EV50). Teeth were embedded in 0.2% agarose gel (pH = 7.4) containing 1 mL 0.1% m-Cresol purple (Sigma-Aldrich, St Louis, MO), which changes color at a pH level of 9.0. Root canals were irrigated with sodium hypochlorite and EDTA using 4 different techniques, and the amount of irrigant was controlled. Standardized digital photographs were taken 20 minutes after the first irrigant was used and were analyzed to determine the amount of extrusion (expressed as a percentage of total pixels). Results: The amounts of apical extrusion obtained in the NI30, NI50, SAF30, SAF50, PUI30, PUI50, EV30, and EV50 groups were 30% (3/10), 50% (5/10), 20% (2/10), 70% (7/10), 40% (4/10), 40% (4/10), 10% (1/10), and 10% (1/10), respectively. The overall extrusion frequency, regardless of the apical preparation size, was 40% (8/20) for needle, 45% (9/20) for SAF, 40% (8/20) for ultrasonic irrigation, and 10% (2/20) for Endo Vac. Although the SAF group showed more extrusion, the percentage of pixels was significantly higher in the needle irrigation group (P<.01). The Endo Vac group showed significantly lower extrusion values than the other techniques in terms of the number of teeth and pixels (P < .05 and P < .01, respectively). Conclusions: The risk of apical extrusion is significantly lower with the Endo Vac in comparison with the 3 other techniques.Publication Metadata only Radiologic Assessment of Periapical Health: Comparison of 3 Different Index Systems(ELSEVIER SCIENCE INC, 2015) GÜMRÜ TARÇIN, BİRSAY; Tarcin, Bilge; Gumru, Birsay; Iriboz, Emre; Turkaydin, Dilek Erbay; Ovecoglu, Hesna SazakIntroduction: The aim of this study was to evaluate observer variations and observer reproducibility in the interpretation of periapical health using the Strindberg system, the periapical index (PAI), and the probability index for radiologic assessment of periapical health. Methods: Four observers read digital periapical images to evaluate the periapical health of 200 root-filled teeth. Each observer evaluated a tooth twice by using the Strindberg system, twice by using the PAI, and twice by using the probability index. Each observation session was held at 1-month intervals. Three scores were used for the evaluations conducted by using the Strindberg system. Both the PAI and the probability index were considered on 5-point scales and were also dichotomized. SPSS for Windows 15.0 software (SPSS InC, Chicago, IL) was used for data analysis, and intra- and interobserver agreements were described by using kappa statistics. Results: The average kappa values of intra- and interobserver agreement calculated for the Strindberg system were 0.53 and 0.36, respectively. The corresponding average kappa values were calculated as 0.48 and 0.39 for the PAI and 0.45 and 0.30 for the probability index. The highest mean proportion values of intra- and interobserver agreement were observed for the dichotomization of the PAI (88.9% and 87.0%, respectively) followed by the dichotomization of the probability index (86.8% and 82.9%, respectively). Conclusions: The Strindberg system has lower intraobserver variation compared with the PAI and the probability index, whereas PAI has lower interobserver variation compared with the Strindberg system and the probability index. The dichotomization of the PAI and the probability index provided higher intra- and interobserver agreement values in the radiologic assessment of periapical health.Publication Open Access Comparison of ProTaper and Mtwo retreatment systems in the removal of resin-based root canal obturation materials during retreatment(WILEY, 2014-04) İRİBOZ, EMRE; Iriboz, Emre; Ovecoglu, Hesna SazakTo evaluate the effectiveness of the ProTaper and Mtwo retreatment systems for removal of resin-based obturation techniques during retreatment. A total of 160 maxillary anterior teeth were enlarged to size 30 using ProTaper and Mtwo rotary instruments. Teeth were randomly divided into eight groups. Resilon+Epiphany, gutta-percha+Epiphany, gutta-percha+AH Plus and gutta-percha+Kerr Pulp Canal Sealer (PCS) combinations were used for obturation. ProTaper and Mtwo retreatment files were used for removal of root canal treatments. After clearing the roots, the teeth were split vertically into halves, and the cleanliness of the canal walls was determined by scanning electron microscopy. Specimens obturated with gutta-percha and Kerr PCS displayed significantly more remnant obturation material than did specimens filled with resin-based obturation materials. Teeth prepared with Mtwo instruments contained significantly more remnant filling material than did teeth prepared with ProTaper. ProTaper files were significantly faster than Mtwo instruments in terms of the mean time of retreatment and time required to reach working length. The Resilon+Epiphany and AH Plus+gutta-percha obturation materials were removed more easily than were the Epiphany+gutta-percha and Kerr PCS+gutta-percha obturation materials. Although ProTaper retreatment files worked faster than did Mtwo retreatment files in terms of removing root canal obturation materials, both retreatment systems are effective, reliable and fast.Publication Metadata only Detection of the unknown components of the oral microflora of teeth with periapical radiolucencies in a Turkish population using next-generation sequencing techniques(WILEY, 2018) İRİBOZ, EMRE; Iriboz, E.; Ozturk, B. Arican; Kolukirik, M.; Karacan, I.; Ovecoglu, H. SazakAim To detect the unknown components of the oral microbiome and the effects of root canal treatment in a Turkish population and to evaluate the changes in microbial diversity in the root canals before and after treatment. Methodology Results Single-rooted central and lateral maxillary incisors with one canal were chosen from 20 patients. Baseline samples of intact intracanal microbiota were collected from 20 root canals of permanent teeth with necrotic pulps using sterile paper points. After root canal preparation, the root canals were filled with a calcium hydroxide paste for 7 days. Calcium hydroxide was removed from root canal with 2.5% sodium hypochlorite and 17% EDTA using passive ultrasonic irrigation (PUI). A second bacteriologic samples were taken with sterile paper points prior to root filling. The samples were processes with DNase-I treatment using next-generation sequencing (NGS). Reduction in bacterial numbers during root canal treatment was evaluated using real-time quantitative PCR (qPCR). All statistical analyses were conducted using the MINITAB 17 software (Minitab Ltd. Co., Coventry, UK). A one-sample t-test was used to analyse the data. Statistical significance was accepted at P Relative abundances of Mycoplasma sp., Paludibacter sp., Tannerella sp., Prevotella spp. and an uncultured species from the order Bacteroidales decreased with root canal preparation and medication (98.7%, 99.8%, 98.8%, 97.7% and 99.3%, respectively), whilst the relative abundances of Methylobacterium sp., Corynebacterium sp. and Streptococcus infantis increased (93.1%, 94.8% and 99.4%, respectively). Considerable numbers of Streptophyta species were detected before and after treatment. The ratio of Agrobacterium sp. in the treated teeth community and the ratio of order Streptophyta in the infected canals had negative correlations with the success of bacterial elimination. Conclusions The combination of NGS and qPCR techniques resulted in detection of previously unknown components of the oral microbiome and the effects of root canal treatment on their relative abundance in a Turkish population.Publication Open Access Shaping ability of novel nickel-titanium systems in printed primary molars.(2022-10-01) İRİBOZ, EMRE; Güçyetmez Topal B., Falakaloğlu S., Silva E. J. N. L. , Gündoğar M., İriboz E.BackgroundManual or mechanized instruments can be used for root canal preparation. Manual instrumentation using K-files is widely used in primary teeth, but there are many limitations. Mechanized root canal preparation can lead to easy access to all canals, decrease instrumentation time, and result in more funnel-shaped root canals, resulting in a more predictable uniform paste fill.AimThis study aimed to evaluate the shaping ability and instrumentation time of VDW.ROTATE™ and EdgeTaper Platinum™ during the preparation of resin-printed primary molars. Hand K-files were used as a reference for comparison.DesignSixty-six resin-based maxillary second primary molars, obtained from extracted tooth cone-beam computed tomography (CBCT) image and printed on a three-dimensional printer, were divided into three groups: VDW.ROTATE™, EdgeTaper Platinum™, and K-files. The specimens were scanned using CBCT imaging before and after root canal preparation. Images were registered using a dedicated software, and changes (Δ) in the canal area, volume, and untouched canal surface were calculated. Instrumentation time was evaluated. Data were statistically analyzed using the SPSS program.ResultsThere was no significant difference among the tested file systems for Δ canal volume and area (p > .05). VDW.ROTATE™, however, showed significantly lower untouched canal surface area than other systems in all roots (p < .001). The VDW.ROTATE™ was found to be significantly faster (6.47 ± 0.39 min) than EdgeTaper Platinum™ (7.71 ± 0.73 min) and K-files (8.22 ± 0.72 min), (p < .05).ConclusionsThe shaping ability and the instrumentation time were directly influenced by the root canal instrumentation system used during the preparation of resin-printed primary molars, with VDW.ROTATE™ being the faster system and associated with the lower amount of untouched canal surface area.Publication Open Access Treatment of maxillary central incisors with internal resorption: Two case reports(2019-04-01) TÜRKAYDIN, DİLEK; İRİBOZ, EMRE; SAZAK ÖVEÇOĞLU, HESNA; Karakaya G., Can G., Türkaydın D., İriboz E., Sazak Öveçoğlu H.Internal root resorption is a rare condition, but it may require complex treatment protocols, depending on the progression. The aim of this case report is to present the treatment protocol and the follow-up results for 2 cases of a right upper central incisor with internal root resorption. A 15-year-old female patient presented with the chief complaint of dental caries. The radiological examination revealed that tooth #21 had internal resorption (IR) in the middle third of the root. The warm vertical condensation technique was applied using a warm obturation system. At 3 years, the tooth was asymptomatic and no lesions were observed. A 48-year-old female patient was referred to the clinic for a routine control. The radiological examination revealed IR in the middle third of tooth #21. As the resorption area was quite wide, cone beam computed tomography was used. The results indicated that there was also external resorption in the buccal part of the root. Therefore, the treatment protocol was changed and the IR area was sealed with mineral trioxide aggregate. At 1 year, the tooth was asymptomatic and no lesions were observed. Keywords: Cone beam computed tomography; internal root resorption; mineral trioxide aggregate; root perforation; trauma.Publication Metadata only Comparison of intracoronal bleaching methods on teeth discolored by different antibiotic pastes(WOLTERS KLUWER MEDKNOW PUBLICATIONS, 2017) TARÇIN, BİLGE; Iriboz, E.; Ozturk, B. A.; Korklu, S.; Tarcin, B.; Berker, Y. G.; Ovecoglu, H. S.Aim: To compare the bleaching efficacy of sodium perborate with different activation methods on crowns discolored by two different antibiotic pastes. Materials and Methods: Eighty-five extracted human incisors were prepared to size #30 using ProTaper rotary instruments. After chemomechanical preparation and irrigation procedures, the specimens received triple antibiotic paste (TAP, n = 40), minocycline paste (MP, n = 40), or calcium hydroxide (n = 5, control group) and coronally sealed with temporary filling material. Spectrophotometric readings were obtained on day 0uweek 4. Data were analyzed with the MannuWhitney U-test and Wilcoxon sign test (P < 0.05). Sodium perborate was then inserted into the pulp chambers of discolored teeth (four subgroups, n = 10) and activated by heat or ultrasonically using two different frequencies and times. Spectrophotometric readings were obtained on days 3u7. Data were analyzed by the MannuWhitney U-test and KruskaluWallis test (P > 0.05). Results: Both groups showed statistically significant coronal discoloration at each time interval (P < 0.01), but their final shades did not significantly differ between the groups (P > 0.05). Although the MP subgroups exhibited more bleaching than the TAP subgroups on days 3 and 7, the difference was not significant (P > 0.05). The bleaching results for the sodium perborate activation techniques did not significantly differ among groups (P > 0.05). Conclusions: Both antibiotic pastes induced crown discoloration that was reversible using all sodium perborate bleaching techniques.Publication Metadata only Effect of Storage Temperature on the Shelf Life of Self-adhesive Resin Cements(QUINTESSENCE PUBLISHING CO INC, 2015) İRİBOZ, EMRE; Ozer, Fusun; Ovecoglu, Hesna Sazak; Daneshmehr, Leila; Sinmazisik, Gulden; Kashyap, Kanupriya; Iriboz, Emre; Blatz, Markus B.Purpose: To compare the bonding performance of three new self-adhesive resin cements to human dentin after storage under two different conditions. Materials and Methods: Buccal, lingual, mesial, and distal dentin surfaces of 36 human molars were abraded to directly below the enamel with #600 SiC papers. The teeth were divided into two main test groups. In the first test group (FT), the cements were kept in a refrigerator (6 +/- 2 degrees C) for three months and then used for the test. The remainder of the cements was kept at a constant room temperature of 19 +/- 2 degrees C for an additional three months, and then used again for the second test group (ST). Each test group comprised 6 teeth and 24 dentin sections. The cements Clearfil SA (CSA), G-Cem (GC), and Bis-Cem (BC) were applied to the surfaces according to the manufacturers' recommendations. After application of the cements to the flat dentin surfaces and light curing, shear bond strengths were determined at a crosshead speed of 0.5 mm/min. Bond strengths were then calculated and expressed in MPa. Data were analyzed with Kruskal-Wallis and Wilcoxon Signed Rank tests. To investigate the cement/dentin interfaces using SEM, the buccal surfaces of three additional teeth were used for each test group. Results: The bond strength values of cement groups were significantly different for the FT and ST groups (p < 0.01). GC showed the highest bond strength values of all materials. There was a difference between the bond strength values of the two testing periods for all materials (p < 0.01). Bond strengths significantly decreased after storage at room temperature. Conclusion: Storage temperatures considerably affect the shelf life of self-adhesive resin cements.Publication Metadata only Assessment of the periapical health of abutment teeth: A retrospective radiological study(WOLTERS KLUWER MEDKNOW PUBLICATIONS, 2015) GÜMRÜ TARÇIN, BİRSAY; Gumru, B.; Tarcin, B.; Iriboz, E.; Turkaydin, D. E.; Unver, T.; Ovecoglu, H. S.Aim: The aim was to examine the technical quality of root fillings and periapical status of root-filled and nonroot-filled teeth restored with crowns and bridge retainers through a retrospective analysis of orthopantomographs (OPTGs) in an adult Turkish subpopulation. Materials and Methods: In this study, the digital OPTGs of adult patients between the ages of 20 and 70 who appealed to the Endodontics Endodontics Department of the Dentistry Faculty at Marmara University (Istanbul, Turkey) for the first time to have their endodontic treatment needs met were used. The periapical health of all teeth restored with crowns and bridge retainers, and the technical quality of the root fillings on abutment teeth were evaluated by radiographic criteria. Results: The survey was carried out using the OPTGs of 1000 adult patients composed of 590 (59.0%) women and 410 (41.0%) men. 4656 (20.9%) of the totally examined 22280 teeth were with crowns and bridge retainers. 986 of the total abutment teeth were root-filled and 458 (46.5%) of them had apical periodontitis (AP) while 3670 of the total abutment teeth were nonroot-filled and 930 (25.3%) of them were with AP. The most commonly treated teeth were premolars (33.8%), followed by molars (26.2%), incisors (23.3%) and canines (16.7%). Technical quality was proved to be adequate in 27.5% of the root fillings. A higher frequency of AP was related to inadequate root fillings (P < 0.01). Conclusion: The frequency of root-filled abutment teeth with AP, nonroot-filled abutment teeth with AP, and technically inadequate root-fillings among teeth with crowns and bridge retainers was high in the selected adult population.Publication Metadata only Shaping ability of modern Nickel-Titanium rotary systems on the preparation of printed mandibular molars(2022-09-01) İRİBOZ, EMRE; Falakaloǧlu S., Silva E., Topal B., İRİBOZ E., Gündoǧar M.© 2022 Wolters Kluwer Medknow Publications. All rights reserved.Introduction: This study aimed to evaluate the shaping ability of TruNatomy (Dentsply Maillefer, Ballaigues, Switzerland), VDW.ROTATE (VDW GmbH, Munich, Germany) and ProTaper Gold (Dentsply Maillefer, Ballaigues, Switzerland) during the preparation of resin-printed mandibular molar mesial root canals. Materials and Methods: Thirty-three printed resin-based mandibular mesial roots with two canals were obtained from extract tooth cone-beam computed tomography (CBCT) image. The printed teeth were divided into three groups (n = 11) according to the system used for root canal preparation: TruNatomy, VDW.ROTATE, and ProTaper Gold. The specimens were scanned using CBCT imaging before and after root canal preparation. Then images were registered using a dedicated software and changes in the canal area, volume, untouched canal surface, and the maximum and minimum dentin wall wear were calculated. Statistical Analysis Used: Data were statistically analyzed using Shapiro-Wilk for normality, one-way ANOVA, and Tukey or Kruskal-Wallis H tests with alpha set at 5%. Results: No differences were observed for changes in the canal area, volume, untouched canal surface area, and minimum dentine wall wear parameters for the whole canal length (P > 0.05). The mean of untouched canal surface area for the TruNatomy, VDW.ROTATE, and ProTaper Gold was 40%, 44%, and 44%, respectively. The maximum dentine wall wear was significantly lower in the ProTaper Gold group than in the TruNatomy and VDW.ROTATE groups (P < 0.05). Conclusions: TruNatomy, VDW.ROTATE, and ProTaper Gold systems showed similar shaping ability in printed resin-based mandibular mesial roots without clinically significant errors. A large amount of untouched canal surface area was observed for all systems.
