Objectives: To assess the effect of glide path on the amount of apically extruded debris after instrumentation with WaveOne and OneShape. Materials & Methods: Forty-eight extracted human mandibular incisors were assigned to 4 groups. In groups 1 and 2, preparation was completed with WaveOne, in groups 3 and 4 canals were prepared with OneShape. Before instrumentation, in groups 1 and 3, glide path was created with PathFile 1, 2, and 3 at working length, whereas in groups  2 and 4, glide path was not performed. The weight of the extruded debris for each group was calculated by comparing the pre-  . . .;and post-instrumentation weights of the eppendorf tubes. The time required for reaching full WL was also recorded. Data were analysed by Kruskal–Wallis and Mann–Whitney U tests. Results: There was no difference in the amount of debris extruded between the single file systems (P=0.234). Time required to reach full WL was significantly decreased by creating a glide path (P< 0.05). Conclusions: Creation of a glide path does not significantly affect the apically extruded debris.

The radicular cyst variously known as periapical, apical periodontal, dentoalveolar or rootend cyst is an inflammatory jaw cyst at the apices of teeth with infected and necrotic pulps. A radicular cyst arises from the epithelial residues in the periodontal ligament as a result of inflammation, usually following death of the pulp. Radicular cysts are the most common odontogenic cystic lesions of inflammatory origin and are managed either by surgical enucleation or by marsupialization. We illustrate the possibility of complete healing of a cystic periapical lesion of huge proportion in permanent dentition of a 58 year-old male patient . . . under general anesthesia with conservation of vital structures and without using any bone substitute Daha fazlası Daha az

Objectives: The aim of the present study was to evaluate the quality of root canal treatments and coronal restorations investigating their influence on the periapical status of endodontically-treated teeth in a Turkish population based on radiographic examination. Materials and Methods: The study included 583 patients referred for routine dental care. A total of 1125 endodontically treated teeth were examined with panoramic radiographs. The quality of root canal fillings and coronal restorations were evaluated according to the criteria determined by Gündüz et al., which were slightly modified from those described by De Moor et al. A . . .pical status was assessed by the Periapical Index (PAI) scores. Results: Out of 1125 endodontically treated teeth, 539 were classified as healthy and 586 as displaying apical periodontitis. Of these 539 subjects, 389 teeth had received quality endodontic treatment. Of 586 teeth with apical periodontitis, 500 had poor endodontic treatment. Four hundred and seventy-five teeth had adequate root canal fillings. Of these teeth, 389 were classified as healthy. Of the 666 teeth with adequate restoration, apical region was classified as healthy for 410 subjects. For the 388 teeth with both adequate coronal restorations and root canal fillings, the success rate was 85.3%. For the 372 teeth with both inadequate coronal restorations and root canal fillings, the success rate was 18.8%. Conclusions: The quality of root fillings in the population living in the back country of Turkey is in general below the acceptable standard and requires substantial improvement.

Objectives: The aim of this study was to compare conventional needle irrigation (CNI), passive ultrasonic irrigation (PUI), and XP-endo Finisher (XPF) techniques in terms of modified triple antibiotic paste (mTAP) removal. Materials and Methods: A total of 30 mandibular premolars were instrumented to a size F3 file. A mixture of mTAP was prepared by mixing 3 antibiotics, including 250 mg ciprofloxacin, 250 mg metronidazole, and 150 mg clindamycin, with 1 ml distilled water and applied into the root canals. The teeth were allocated into 3 equal groups, irrigation/agitation was performed and teeth were divided into two halves. The rem . . .oval of mTAP was evaluated with a scanning electron microscope by using the 4 grade scoring system. Results: In the apical thirds, significant difference was found between PUI and CNI groups (p < 0.05), whilst no significant difference was found among the other irrigation activation regimens (p > 0.05). No statistically significant difference was found between all groups in the middle third. In the coronal thirds, XPF removed significantly more mTAP than the CNI group (p < 0.05). However, no difference was recorded among other groups (p > 0.05). Conclusions: Passive ultrasonic irrigation and XPF file agitation demonstrated superior efficacy in removing mTAP from root canals compared to CNI. © 2019 Cumhuriyet University Faculty of Dentistry.Amaç: Bu çalişmanin amaci klasik şiringa irrigasyonu (CNI), pasif ultrasonik irrigasyon (PUI) ve XP-endo Finisher (XPF) tekniklerinin modifiye üçlü antibiyotik patini (mTAP) uzaklaştirmasi açisindan karşilaştirilmasidir. Gereç ve Yöntemler: Otuz adet alt çene küçük azi dişi F3 eğe boyutuna kadar prepare edildi. mTAP, 250 mg siprofloksasin, 250 mg metronidazol, and 150 mg klindamisin içeren karişimin 1ml distile su ile kariştirilmasi ile hazirlandi ve kök kanallarina uygulandi. Dişler üç eşit gruba ayrildi, irrigasyon/aktivasyon uygulandi ve dişler iki eşit parçaya ayrildi. mTAP uzaklaştirilmasi trama elektron mikroskobu ile 4 aşamali skorlama metodu ile değerlendirildi. Bulgular: Apikal üçlüde CNI ile PUI gruplari arasinda anlamli fark bulunmasina rağmen (p < 0,05), diğer irrigasyon aktivasyon yöntemleri arasinda anlamli fark bulunmadi (p > 0,05). Orta üçlüde tüm gruplar arasinda istatistiksel olarak anlamli bir fark bulunmadi (p > 0,05). Koronal üçlüde, XPF CNI grubundan anlmali derecede daha fazla mTAP uzaklaştirdi (p < 0,05). Ancak diğer gruplar arasdina anlamli fark görülmedi (p > 0,05). Sonuçlar: Pasif ultrasonik irrigasyon ve XPF eğe aktivasyonu, klasik şiringa irrigasyonuna göre kök kanallarindan mTAP'in uzaklaştirilmasinda daha üstündür. © 2019 Cumhuriyet University Faculty of Dentistry Daha fazlası Daha az

Objectives: The aim of this study was to evaluate how microshear bond strength of different adhesive resin cements are affected by dentin desensitizers application and preparation depth. Materials and Methods: One hundred and forty-four maxillary incisors were randomly divided into two groups according to dentin preparation depth (0.8 and 1 mm) and each group subdivided into four dentin desensitizers, Nd:YAG (Neodymium-doped Yttrium aluminum Garnet) laser and control groups. The dentin desensitizers used were Gluma [Glutaraldehyde/ Hydroxyethyl methacrylate (HEMA)], BisBlock (Oxalate) Vivasens-Potassium Fluoride (KF) and Admira Prot . . .ect (Ormocer/HEMA), respectively. Three dual cure resin based luting cement (RelyX ARC; Variolink II and Maxcem Elite) were used to create a 0.7 mm diameter and 1 mm height cylindirical shape buid-up in tygon tubes (n=10). Micro-shear bond strength (µSBS) test was performed at a crosshead of speed of 0.5 mm/min using a Universal testing device. Then tooth surface was investigated by steromicroscope and scanning electron microscopy (SEM). Data were analyzed using Kruskal-Wallis, Mann-Whitney U and Chi-Square (X2) tests. (p = 0.05) Results: There was no statistically difference between the groups at 0.8 mm preparation depth. At 1 mm preparation dept RelyX ARC + Gluma groups' mean bond strength value (23.96 ± 6.66 MPa) was found statistically lower according to the other groups (p < 0.05). RelyX ARC + Laser groups' mean bond strength value (37.33 ± 7.39 MPa) was found statistically higher according to the other groups (p < 0.05). Conclusions: The use of desensitizing agents affected the bond strength of the resin cements to superficial dentin. Gluma desensitizer affected negatively µSBS of RelyX ARC resin cement at 1 mm depth. Application of Nd:YAG laser to superficial dentin showed positive effects to the dentin surface and bond strength. Other desensitizing agents showed no significant effects on the resin bond strength (p > 0.05). © 2019 Cumhuriyet Dental Journal Daha fazlası Daha az

The aim of this study was to evaluate the effects of brand, holding solution and storage periods on dimensional stability of irreversible hydrocolloid impression materials. Impressions were taken from a master maxillary typodont, using a newly designed device and five different irreversible hydrocolloid impression materials. A total of 245 impressions were taken and divided into a control group, two main groups and three subgroups through storing procedure and time. Stone models were obtained for each model and five different dimensions were measured and compared to each other. Comparison of the groups according to brand of irrevers . . .ible hydrocolloid impression materials showed statistically significant differences. While the storage period was statistically important at all distances, storage condition was significant only at some distances. Irreversible hydrocolloid impression materials can be stored in holding solution or sealed plastic bags up to two weeks. Type of the impression material, storage condition and storage period may affect dimensions. © 2017 Cumhuriyet University Faculty of Dentistry Daha fazlası Daha az
