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 Multidisciplinary Treatment Approach in a Patient with History of Nasopharyngeal Carcinoma(2014) DOĞAN, BAŞAK; Yavuz, Atacan; Ağralı, Omer Birkan; Calışkan, Zeynep Lale; Türkaydın, Dilek; Sertgöz, Atilla; Kuru, Bahar; Doğan, BaşakRadiotherapy in NPC patients has side effects on the dentition, which affects quality of life dramatically. This case report presents multidisciplinary dental treatment approach in a 17-year-old male patient with a history of nasopharyngeal carcinoma (NPC), which was treated with chemotherapy and radiotherapy. The adolescent patient applied to dental hospital 4 years after the radiotherapy with aesthetic and functional problems on dentition affecting psychological, social, and physical aspects of his life. The dentition of the patient demonstrated the severe destruction as a devastating side effect of radiotherapy. With a successful multidisciplinary approach, our patient's aesthetics, function, and self-confidence were obtained. Well-established procedures, which include preventative care and maintenance, can reduce the duration and expenses of the treatment and help in challenging the life-long complications of radiotherapy.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 Efficacy of XP-Endo Finisher in the Removal of Triple Antibiotic Paste from Immature Root Canals(ELSEVIER SCIENCE INC, 2017) TÜRKAYDIN, DİLEK; Turkaydin, Dilek; Denzil, Erhan; Basturk, Fatima Betul; Ovecoglu, Hesna SazakIntroduction: The aim of this study was to evaluate and compare the effectiveness of the XP-Endo Finisher (FKG Dentaire, La Chaux-de-Fonds, Switzerland) with passive ultrasonic irrigation (PUI) and needle irrigation in the removal of triple antibiotic paste (TAP) from the straight immature root canals of extracted teeth. Methods: Thirty-four freshly extracted single-rooted teeth were used. All canals were prepared up to the ProTaper F5 file (Dentsply Maillefer, Ballaigues, Switzerland). Apices were drilled to simulate teeth with immature apices. The canals were filled with TAP, sealed, and incubated at 37 degrees C and 100% humidity for 1 month. Samples were randomly assigned to 3 experimental groups according to the method used for TAP removal: XP-Endo Finisher, PUI, and needle irrigation (n = 10). Then, the roots were split into 2 halves. The amount of TAP residue in the apical portion of each segment was evaluated using a scanning electron microscopy and scored. Results: The amount of remaining TAP was significantly lower in the XP-Endo Finisher group compared with the needle irrigation and PUI groups (P < .05). Between the needle irrigation and PUI groups, there were no statistically significant differences (P> .05). Conclusions: Within the limitations of this study, the XP-Endo Finisher removed significantly more TAP than needle irrigation and PUI.Publication Open Access Does the mixing and placement regime affect the pH of Mineral Trioxide Aggregate?(2019) TÜRKAYDIN, DİLEK; DİLEK TÜRKAYDIN;Fatıma Betül BAŞTÜRK;Mohammad Hossein NEKOOFAR;Mahir GÜNDAY;Paul DUMMERAim:The objective of this study was to measure in a laboratorysetting the pH of tooth coloured ProRoot MTA and MTAAngelus following various mixing and placement techniques,including mechanical mixing, manual mixing and indirect ultrasonicactivation.Materials and Method: Tooth coloured ProRoot MTA andWhite MTA Angelus were used. One gram of each powderwas mixed with a 0.34 g of distilled water that were allocatedto eight experimental groups, each containing three specimens.Four groups were prepared by mechanical mixing ofcapsules for 30 s at 4500 rpm the other four were mixed manually.Half of the specimens in each group were placed inmoulds using indirect ultrasonic activation. pH values wererecorded directly from within the freshly mixed material andwere analyzed using one-way ANOVA at a 0.05 level of significance.Results: No significant difference in pH was found betweenthe mixing and placement techniques or the materials tested.The highest pH value recorded was in the ProRoot group thatwas mixed manually and placed ultrasonically (11.64). TheAngelus group, which was mixed manually without an ultrasonicagitation, had the lowest pH values (10.42).Conclusion: Mechanical mixing and ultrasonication conferredno significant disadvantage in terms of the initial pH ofthe material. Since mechanical agitation of encapsulated cementsprovides more consistent mixes, it might be possible touse this technique combined with ultrasonic agitation as analternative to manual mixing, both in clinical and in laboratoryconditions, in order to achieve standardization of the materialso as to enhance its properties.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.
