Publication Metadata only The effects of different irrigation protocols on removing calcium hydroxide from the root canals.(2016-07-01T00:00:00Z) Dincer, ASİYE NUR; ÜSTÜN, Y; ASLAN, T; SAGSEN, B; DİNÇER, ASİYE NURPublication Metadata only Comparison of Conventional Syringe, CanalBrush, EndoActivator, Photon-Induced Photoacoustic Streaming, and Manual Instrumentation in Removing Orange-Brown Precipitate: An In Vitro Study(2017-06-01) Dincer, ASİYE NUR; Guneser, MEHMET BURAK; ARSLAN, Dilara; GÜNEŞER, MEHMET BURAK; DİNÇER, ASİYE NURObjective: The aim of this in vitro study was to compare the various techniques for removing precipitate formed after irrigation with sodium hypochlorite (NaOCl) and chlorhexidine (CHX). Background data: It is still unclear whether different irrigant activation systems can effectively remove precipitate that is firmly attached to the root canal walls. Methods: Eighty-two extracted single-rooted human teeth were instrumented by using the ProTaper rotary system. The roots were irrigated with 5% NaOCl and then 2% CHX to form orange-brown precipitate on the root canal walls. The teeth were sectioned longitudinally, and the amount of precipitate on the canal walls was measured under a stereomicroscope at 15xmagnification before the root halves were reassembled. Then, conventional syringe irrigation (CSI), CanalBrush (CB), EndoActivator (EA) system, photon-induced photoacoustic streaming (PIPS), and manual instrumentation (MI) techniques were used to remove the precipitate, during which 5mL of distilled water was used for 1min. The amount of precipitate remaining on the canal walls was measured, and the percentage of precipitate removed was calculated. Data were analyzed by using the Kruskal-Wallis and Mann-Whitney U tests (p=0.05). Results: All experimental groups contained residual precipitate. The precipitate was more effectively removed in the MI group than in the other groups (p0.05). Conclusions: None of the techniques used was able to completely remove the orange-brown precipitate from the root canal surfaces.Publication Metadata only The Effect of Different Filling Techniques On Apical Crack Initiation and Propagation After Retreatment Procedures(2019-12-01T00:00:00Z) Güneşer, Mehmet Burak; Dinçer, Asiye Nur; Kaplan, Fatma; Kebudi Benezra, Mira; DİNÇER, ASİYE NUR; GÜNEŞER, MEHMET BURAK; KAPLAN, FATMAPublication Metadata only Kök Kanallarının Şekillendirilmesinin Değerlendirilmesinde Kullanılan Araştırma Yöntemleri(2017-06-01T00:00:00Z) GÜNEŞER, MEHMET BURAK; DİNÇER, ASİYE NUR; ARSLAN, DİLARA; GÜNEŞER, MEHMET BURAK; DİNÇER, ASİYE NURPublication Metadata only Use of cone-beam computed tomography to evaluate root and canal morphology of mandibular first and second molars in Turkish individuals(2013-07-01T00:00:00Z) DEMİRBUĞA, SEZER; Sekerci, Ahmet-Ercan; DİNÇER, Asiye Nur; Cayabatmaz, Muhammed; Zorba, Yahya-Orcu; DİNÇER, ASİYE NURObjective: The aim of this study was to investigate the root and canal morphology of mandibular first and second molars in a Turkish population by using cone beam computed tomography (CBCT). Study design: CBCT images of mandibular first (n = 823) and second molar (n = 925) teeth from 605 Turkish patients were analyzed. The root canal configurations were classified according to the method of Vertucci. Results: The majority of mandibular molars (95.8% of first molars, 85.4% of second molars) had two separate roots; however, three roots were identified in 2.06% of first molars and 3.45% of second molars. C-shaped canals occurred 0.85% of first molars and 4.1% of second molars. Three canals were found in 79.9% of first molars and 72.8% of second molars. Most distal roots had a simple type I configuration, whereas mesial roots had more complex canal systems, with more than one canal. The most common root morphology of first and second molars is the two rooted morphology with three canals. Both the mesial and distal roots showed wide variations in canal anatomy with type IV and type I canal configuration predominating in the mesial and distal roots, respectively. Conclusion: Vertucci type I and IV canal configurations were the most prevalent in the distal and mesial roots, respectively, of both the mandibular first and second permanent molar teeth.Publication Metadata only Do the Sealer Solvents Used Affect Apically Extruded Debris in Retreatment?(2015-09-01T00:00:00Z) Dincer, ASİYE NUR; Canakci, Burhan Can; Er, Ozgur; DİNÇER, ASİYE NURIntroduction: We evaluated apically extruded debris in the retreatment of root canals filled with different root canal sealers and gutta-percha using different solvents. Methods: Ninety human mandibular central and lateral teeth were prepared using the Reciproc #25.08 nickel-titanium system (VDW GmbH, Munich, Germany) and were divided randomly into 6 groups. In groups 1, 2, and 3, root canals were filled with epoxy resin based sealer and gutta-percha, and in groups 4, 5, and 6, root canals were filled with zinc oxide eugenol based sealer and gutta-percha. Each tooth was placed in a glass vial experimental apparatus. All root canal fillings were removed with the ProTaper Retreatment nickel-titanium system (Dentsply Maillefer, Ballaigues, Switzerland). During the retreatment procedure, in group 1, Resosolv (Pierre Rolland, Merignac, France) was used; in group 4, Endosolv E (Septodont, Paris, France) was used; and in groups 2 and 5, Guttasolv (Septodont) was used as the solvent. In the control groups (groups 3 and 6), no solvent was used. Reciproc #40 .06 was used for the final preparation. The times required for retreatments were recorded. Results: The weight of the extruded debris and the time required for retreatment were decreased significantly in the groups in which a solvent that was intended specifically for the root canal sealer was used (groups 1 and 4). In the Guttasolv groups (groups 2 and 5), the amount of apically extruded debris and the time required decreased for both root canal sealers. Conclusions: The amount of apically extruded debris and the duration of retreatment were reduced by the use of a solvent specific to the sealer compared with a gutta-percha solvent or no solvent.Publication Metadata only The effect of a new-generation flowable composite resin on microleakage in Class V composite restorations as an intermediate layer.(2013-05-01T00:00:00Z) Dincer, ASİYE NUR; ARSLAN, S; DEMIRBUGA, S; ÜSTÜN, Y; ÇANAKÇI, BC; ZORBA, YO; DİNÇER, ASİYE NURPublication Metadata only Evaluation of Debris Extruded Apically during the Removal of Root Canal Filling Material Using ProTaper, D-RaCe, and R-Endo Rotary Nickel-Titanium Retreatment Instruments and Hand Files(2014-12-01T00:00:00Z) TOPÇUOĞLU, Hüseyin Sinan; Akti, Abmet; Tuncay, Oznur; Dincer, Asiye Nur; Duzgun, Salib; Topcuoglu, Gamze; DİNÇER, ASİYE NURIntroduction: The aim of this study was to evaluate the amount of debris extruded apically during the removal of root canal filling material using ProTaper (Dentsply Maillefer, Ballaigues, Switzerland), D-RaCe (FKG Dentaire, La Chaux-de-Fonds, Switzerland), and R-Endo (Micro-Mega, Besancon, France) nickel-titanium (NiTi) rotary retreatment instruments and hand files. Methods: Sixty extracted single-rooted mandibular premolar teeth were prepared with K-files and filled with gutta-percha and AH Plus sealer (Dentsply DeTrey, Konstanz, Germany). The teeth were then randomly assigned to 4 groups (n = 15 for each group) for retreatment. The removal of canal filling material was performed as follows: hand files, ProTaper, D-RaCe, and R-Endo retreatment instruments. Debris extruded apically during the removal of canal filling material was collected into preweighed Eppendorf tubes. The tubes were then stored in an incubator at 70 degrees C for 5 days. The weight of the dry extruded debris was established by subtracting the preretreatment and postretreatment weight of the Eppendorf tubes for each group. The data obtained were analyzed using 1-way analysis of variance and Tukey post hoc tests. Results: All retreatment techniques caused the apical extrusion of debris. Hand files produced significantly more debris when compared with ProTaper, D-RaCe, and R-Endo rotary systems (P .05). Conclusions: The findings showed that during the removal of root canal filling material, rotary NiTi retreatment instruments used in this study caused less apical extrusion of debris compared with hand files.Publication Metadata only Evaluation of apically extruded debris associated with several Ni-Ti systems.(2015-07-01T00:00:00Z) Dinçer, ASİYE NUR; ÜSTÜN, Y; ÇANAKÇI, BC; ER, O; DÜZGÜN, S; DİNÇER, ASİYE NURPublication Metadata only Evaluation of apically extruded debris during root canal retreatment with several NiTi systems(2015-12-01T00:00:00Z) Dincer, ASİYE NUR; Er, O.; CANAKCI, B.
