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 Empress II onlays(2012-01-01) TAĞTEKİN, DİLEK; SAZAK ÖVEÇOĞLU, HESNA; YANIKOĞLU F., özyöney g., Özyöney N., TAĞTEKİN D., SAZAK ÖVEÇOĞLU H., Gunday m.Publication Metadata only Evaluation of apical periodontitis and technicalerrors in endodontically-treated teeth usingperiapical radiography and cone-beam computedtomography(2021-05-01) SAZAK ÖVEÇOĞLU, HESNA; KAPLAN T., SAZAK ÖVEÇOĞLU H.Publication Metadata only Postoperatif ağrı(Türkiye Klinikleri Yayınevi, 2022-10-01) ÖZDEN, İDİL; SAZAK ÖVEÇOĞLU, HESNA; Özden İ., Sazak Öveçoğlu H.Dental anksiyetenin başlıca kaynağı olan ağrı; hastalar ve klinisyenler tarafından istenmeyen bir durumdur. Bu sebeple kanal tedavisi sırasında ve sonrasında ağrı kontrolü endodonti pratiğinde büyük öneme sahiptir. Birçok hazırlayıcı faktörü olan ve oldukça bireysel değişkenlikler gösteren postoperatif ağrı da endodontik acilin bir parçasıdır. Bu sürecin iyi yönetilebilmesi için; klinisyenin postoperatif ağrıdan sorumlu olan faktörler hakkında bilgi sahibi olması ve hastayı risk faktörlerine göre hazırlayarak postoperatif ağrıyı azaltmak için önlemler alması gerekmektedir. Postoperatif ağrı; tedavi öncesi,sonrası ve tedavi sırasında pek çok durumla ilişkili multifaktöriyel bir olgudur. Preoparatif ağrı varlığı,cinsiyet,yaş,diş tipi ve lokasyonu, endişe/anksiyete, pulpal durum, periapikal lezyon varlığı, profilaktik ilaç kullanımı, anestezik solüsyon, çalışma uzunluğu belirleme yöntemi, enstrümentasyon, irigasyon ve aktivasyon, kanal dolgu tekniği, oklüzal redüksiyon, postoperatif ilaç kullanımı, kanal içi medikament uygulaması, tek veya çok seanslı endodondik tedavi uygulaması postoperatif ağrı oluşumuyla ilişkisi araştırılan faktörlerdir.Publication Metadata only Evaluation of smear layer removal after use of a canal brush: an SEM study(MOSBY-ELSEVIER, 2010) SAZAK ÖVEÇOĞLU, HESNA; Garip, Yildiz; Sazak, Hesna; Gunday, Mahir; Hatipoglu, SedaObjective. The objective of this study was to evaluate smear layer removal after using the new CanalBrush (Coltene/Whaledent GmbH+Co. KG, Germany). Study design. Twenty extracted maxillary anterior teeth were randomly divided into 2 equal groups. The canals of the teeth in each group were instrumented with ProTaper Universal rotary files (Dentsply Maillefer, Switzerland). Following each file use, the root canals in both groups were irrigated with 5.25% NaOCl and 15% EDTA. At the end of instrumentation, the canals in group 2 were flushed with 15% EDTA, then a CanalBrush was used for 30 seconds, and a final irrigation was conducted with 5.25% NaOCl. All teeth were processed for scanning electron microscopy (SEM), and the removal of the smear layer was examined in the apical, middle, and coronal thirds. Analyses of SEM images were performed by 2 independent evaluators in a blinded manner and using a 4-point scoring system. Results. The middle and apical thirds of the root canals in group 2 showed lower average scores than those in group 1, but the difference was not statistically significant. There was no significant difference in the coronal score between the groups (P>.05). Conclusions. Irrigating with brushing tended to produce cleaner canal walls, but irrigating brushing was not significantly better than irrigation alone in removing the smear layer on the canal walls.

Sixty extracted teeth with a single root and canal were used in this study. After chemomechanical preparation, the root canals in the experimental groups were filled with gutta-percha and AH Plus or CeraSeal, while those of the control groups were filled with gutta-percha only. Resiproc or WaveOne Gold were used for the removal of the root canal filling. Temperature changes in the middle and apical third of the root surface were recorded by a thermal camera at different time intervals. Among the groups using the same sealer, the temperature rise observed on the root surface at the end of 90 s in the Resiproc groups was found to be significantly higher than that of the WaveOne Gold groups.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 A scanning electron microscopic study of external root resorption in replanted dog teeth(1995) TÜRKMEN, CAFER; Günday, M.; Sazak, H.; Türkmen, C.Root resorption after replantation of mature permanent dog incisors was examined by scanning electron microscopy. Three groups consisting of three extracted teeth each were kept in a saline solution for 5, 30, and 120 min before replantation. The first group was replanted with the pulp intact. The second and third groups were replanted after root canal filling by Calciobiotic Root Canal Sealer. After 90 days, the teeth were extracted and the apical root surfaces were examined. Severe inflammatory root resorption was observed in the first (intact pulp) group. For the root canal filled teeth, the degree of root resorption was observed to be much less in those kept in saline for 30 min than in those kept for 120 min.
