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 Metadata only The effect of operator-induced variability on the physical properties of ProRoot MTA(WOLTERS KLUWER MEDKNOW PUBLICATIONS, 2020) TÜRKAYDIN, DİLEK; Kosar, M. Aytore; Basturk, F. B.; Turkaydin, D.; Nekoofar, M. H.Aims: The aim of this study was to compare the influence of operators on the microhardness and compressive strength of mineral trioxide aggregate (MTA). Materials and Methods: Forty dental specialists were asked to prepare a series of MTA samples. The tested material was ProRoot MTA (DentsplyMaillefer, Switzerland). Each participant prepared one sample to a consistency they considered acceptable for use in practice (improvised group) and another one according to the manufacturer's recommended water-to-powder (WP) ratio (pre-weighed group). The samples were incubated at 37 degrees C and 95% humidity for 4 days. Parameters evaluated in this study were microhardness and compressive strength. Results: Operators mixed MTA samples with varying WP ratios. However, there was no significant difference between the microhardness and compressive strength values of MTA samples between the improvised, the pre-weighed and the control groups. MTA was mixed in a thicker consistency than the manufacturers recommended ratio (0.33) by 62.5% of the operators. Conclusion: According to the results of this study, even though the WP ratios that were utilized in the clinical setting vary, microhardness and compressive strength values of MTA was not significantly affected.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 Metadata only Acil endodontik tedavilerde anestezi(2022-08-01) GÖKER KAMALI, SELİN; TÜRKAYDIN, DİLEK; Göker Kamalı S., Türkaydın D.Endodontik acil durum, pulpal veya periapikal dokuların inflamasyon veya enfeksiyonunun neden olduğu ağrı veya şişlik olarak tanımlanmaktadır.

E., GÖKER KAMALI S., TÜRKAYDIN D.© 2022, The Author(s), under exclusive licence to Springer-Verlag London Ltd., part of Springer Nature.This study aimed to assess the apical extrusion of sodium hypochlorite in immature teeth caused by needle irrigation, ultrasonic irrigation, EDDY, Er:YAG, and diode lasers. Seventy-five human maxillary anterior teeth were selected. After the apical 3 mm of the roots was resected, the canal lumen was enlarged with #2 to #5 Gates-Glidden burs. The teeth were fixed to the lid of a flat-sided clear plastic container, and the plastic containers were filled with 0.2% agarose gel containing 1 mL of 0.1% m-cresol purple. Then, the specimens were allocated into five groups according to the irrigation activation techniques: needle irrigation, ultrasonic irrigation, EDDY, Er:YAG laser, and diode laser. The apical extrusion of sodium hypochlorite caused the color change in the gel. The containers were digitally photographed, and the percentage of pixels of irrigant extrusion (the color change) in each photograph was calculated. The diode laser group showed a significantly lower percentage of pixels than needle irrigation, EDDY, and Er:YAG laser (p 0.05). All the groups caused irrigant extrusion in the immature teeth. The diode laser and ultrasonic irrigation caused less sodium hypochlorite extrusion than EDDY and Er:YAG laser. The needle irrigation showed more irrigant extrusion than the only diode laser group.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 EndoActivator, CanalBrush, and Passive Ultrasonic Irrigation in the Removal of Calcium Hydroxide Paste with Iodoform and p-chlorophenol from Root Canals(WOLTERS KLUWER MEDKNOW PUBLICATIONS, 2020) TARÇIN, BİLGE; Turkaydin, D.; Basturk, F. B.; Goker, S.; Tarcin, B.; Berker, Y. Garip; Ovecoglu, H. SazakAims: We evaluated and compared EndoActivator, CanalBrush, and passive ultrasonic irrigation (PUI) in the removal of calcium hydroxide and calcium hydroxide with iodoform and p-chlorophenol paste (Calcipast Forte) from artificial standardized grooves in the apical third of root canals. Materials and Methods: A total of 34 mandibular premolars were prepared and then split longitudinally. A standardized groove was prepared in the apical part of both segments. The grooves were filled with either calcium hydroxide or Calcipast Forte, and the segments were reassembled. CanalBrush, EndoActivator, or PUI were used. The amount of remaining medicament was evaluated using a four-grade scoring system. Results: None of the irrigation methods could completely remove the pastes from the grooves. More Calcipast Forte paste was detected compared with calcium hydroxide (P < 0.01). PUI was the least effective method in removing Calcipast Forte. Conclusions: It was more difficult to remove Calcipast Forte than a water-based calcium hydroxide paste.Publication Open Access Effect of different obturation techniques on sealer penetration into dentinal tubules after final irrigation with xp-endo finisher file(2022-07-01) GÖKER KAMALI, SELİN; TÜRKAYDIN, DİLEK; Demir E., Göker Kamalı S., Türkaydın D.The first objective of this research was to evaluate the effectiveness of XP-Endo Finisher on dentinal tubule penetration of irrigation solution using confocal laser scanning microscopy. The main purpose of this research was to compare the effect of cold lateral condensation, continuous wave obturation and core-carrier based techniques on sealer penetration. Sixty mandibular premolars were prepared and allocated into two experimental groups (n=30) as the final irrigation technique and obturation technique experiment. In the final irrigation technique experiment, final irrigation was performed with XP-Endo Finisher, passive ultrasonic irrigation (PUI) and conventional needle irrigation (CNI) (n=10). The roots in the obturation technique experiment were also assigned into 3 groups and obturated with cold lateral condensation, continuous-wave obturation and core-carrier techniques (n=10). The most effective activation method, which emerged as a result of the first part of this study, was used as the final irrigation method in the obturation technique experiment. Then, all roots were sectioned in 1-mm-thick slices at 3mm from the apex for scanning. In terms of depth and percentage of material penetration, CNI exhibited significantly the lowest values and no significant difference was found between others. Also, there was no significant difference among obturation methods. In conclusion, XP-Endo Finisher and PUI are more effective than CNI on irrigant penetration. Sealer penetration into dentinal tubules is independent of obturation techniques.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.
