The roots were respectively irrigated with 5% NaOCl and 2% CHX solutions, and an orange-precipitate formed on the canal walls. The teeth were divided longitudinally, and the precipitate was evaluated with a dental operating microscope (DOM) at 16x magnification before the sections were joined. The halves of roots were then combined, and EDDY, passive ultrasonic activation (PUI) and manual irrigation (MI) techniques were applied for 1 min with 5 ml of distilled water to remove the precipitate. The halves were re-evaluated under the DOM and the residual of percentage of precipitate removed was calculated. The data were evaluated statistically by Kruskal-Wallis tests.</p> <p>&nbsp;<strong>Results:</strong> A residual orange-precipitate was found in all groups. Although the orange precipitate was effectively removed in the EDDY group, there was no statistically significant difference among EDDY, PUI and MI (p&gt; 0.05).</p> <p><strong>Conclusions: </strong>None of the techniques used completely removed the orange precipitate from the root canal surfaces. Among the irrigation activation techniques, there was no superior technique for removing the orange-precipitate from the root canals.&nbsp;</p> <p>&nbsp;</p> <p><strong>How to cite this article:&nbsp;</strong>İnce Yusufoglu S, Keskin NB.

All patients were initially treated by curettage and physiological saline irrigation. Patients were then divided into 4 groups. Group 1 was considered the control group; no other biomaterials were administered after curettage and physiological saline irrigation. All other groups were administered an additional treatment in the socket after curettage and physiological saline irrigation (Group 1 – Alveogyl; Group 2 - 0.8% HA; Group 3 - 0.2% CHX). Patents were evaluated before surgery as well as days 3 and 7 after surgery. The postoperative evaluations included: Visual analog scale(VAS) pain scores, the presence of clinical signs and symptoms of exposed alveolar bone, disorganized blood clot, inflammation around the socket, and bad odor and taste.</p> <p><strong>Results: </strong>Sixty-seven patients were included in the study. There was no statistically significant difference between groups in all control evaluations (p&gt;0.05). There was significantly reduced inflammation around the extraction socket on postoperative day 7 in the CHX group compared to that in the control group (p&lt;0.05). No other significant changes in clinical signs and symptoms were observed among groups.</p> <p><strong>Conclusion:</strong> There was no significant difference between curettage with physiological saline irrigation alone and the addition of Alveogyl, 0.8% HA, or 0.2% CHX in the reduction of pain in alveolar osteitis. Nonetheless, CHX may reduce inflammation around the extraction sockets.</p> <p>&nbsp;</p> <p><strong>How to cite this article:</strong> Dereci Ö, Görkem T, Koşar YÇ.

The purpose of this study is to investigate the chemical composition and surface energies of white (WPTG) and black porous titanium granules (PTG), bovine bone graft and equine-derived bone graft through energy dispersive X-ray spectrometry (EDX) analysis of the comparison.</p> <p><strong>Methodology: </strong>The surface chemical compositions of PTG, WPTG, bovine bone graft and equine-derived bone graft were measured by EDX analysis. All graft materials’ morphologic characteristics such as particle and granule dimension were evaluated with Scanning Electron Microscopy (SEM). The EDX measurement of samples was evaluated at between x85 to x50000 magnification.</p> <p><strong>Results: </strong>PTG grafts showed elements of sodium (%8.88±9.98), chlor (2.44±1.96) and aluminum (0.99±0.37) as well as titanium (90.06±11.34) molecule at x5000 magnification. In WPTG, titanium (%34.55±6.41) and oxygen (%65.44±6.42) molecules were detected. EDX analyses have detected the presence of sodium, calcium, and phosphorus in the equine-derived and bovine bone graft.</p> <p><strong>Conclusion:</strong> It has been found that PTG surface was not made of pure titanium, it has different chemical molecules at larger magnifications and xenografts exhibited different organic material content. Cell culture and experimental studies are needed to establish a relationship between the different commercial dental grafts and their regenerative properties.</p> <p><strong>How to cite this article:&nbsp;</strong>Berceste G, Uraz A, Çetiner D.

The main inclusion criteria were radiographic evidence of apical periodontitis (minimum size of 2.0 × 2.0&nbsp;mm) and a diagnosis of pulpal necrosis confirmed by a negative response to vitality tests. All the root canals were prepared using a standard shaping technique and irrigation procedure. In Groups I and III, the root canals were obturated during the first visit following chemo-mechanical preparation. In Groups II and IV, the root canals were medicated with calcium hydroxide and obturated during a second visit, 1 week later. In Groups III and IV, after the chemo-mechanical preparation, the root canals were additionally irradiated by an 810-nm diode laser at 1.5 W output for 20 seconds. A modified visual analogue scale was used to measure pain at 4, 8, 12, 24, and 48 hours and 7 days after the treatment.</p> <p><strong>Results: </strong>There was no statistically significant difference between the groups in terms of post-operative pain at any time during the observation period (p &gt; .05). Post-operative pain occurred only at 8 and 12 hours and at 1, 2, and 3 days in all groups. There was no correlation between the results regarding age, gender, periapical index scores, or tooth type.</p> <p><strong>Conclusion:</strong> The use of low-level laser therapy had no significant effect on the incidence of post-operative pain, and single-visit root canal treatment may be a strong alternative to multi-visit treatment.</p> <p><strong>How to cite this article:&nbsp;</strong>Özkan Özcan H, Haznedaroğlu F, Gökyay S.

The aim of this study was to evaluate the quality of endodontic treatment, technical error types seen in root canals and the periapical condition of the teeth in patients undergoing periapical surgery, and thus to analyze the reasons leading to periapical surgery.</p> <p><strong>Methodology: </strong>Clinical and radiographic data of 301 periapical surgery cases were retrospectively evaluated in this study. The causes of periapical surgery were classified into technical and biological reasons.</p> <p><strong>Results: </strong>In this study, 51.8 % of periapical surgery cases were related to biological factors and 48.2 % were related to technical factors. Maxillary anterior teeth were the most common teeth undergoing apical surgery with a rate of 66,8 %.&nbsp; The most common technical reasons were non-homogeneous filling (15,6 %), underfilling (12,0 %) and overfilling (9,6 %). The most common biological reasons were cysts (30,2 %), traumas (16,6 %) and apical abscess (5,0 %).&nbsp; 37.5% of cases undergoing periapical surgery, the diameter of the cystic lesion was 10mm or more.</p> <p><strong>Conclusion:</strong> The number of cases of apical periodontitis is increasing in the community due to insufficiently filled root canals. Increasing the quality of root canal treatments applied by dentists will reduce the need for periapical surgery by reducing the incidence of apical periodontitis.</p> <p>&nbsp;</p> <p><strong>How to cite this article:&nbsp;</strong>Ekici Ö.

The aim of this study was to investigate the frequency of second root canals in mandibular incisors and the prevalence of root canal separation in the cervical, middle and apical thirds of cases with 2 root canals.</p> <p><strong>Methodology:</strong> Retrospective cone-beam computed tomography (CBCT) datas of 500 patients seen between 2016 and 2018 were evaluated. A total of 300 patients, 134 males and 166 females, aged 13-71 years (mean age 39.34±13.44) were included in this study. A total of 587 central mandibular incisors and 582 lateral mandibular incisors were examined. The number of roots and root canal morphology based on the Vertucci’s classification were analyzed. The effect of gender on the prevalence of root canal anatomy was also evaluated.</p> <p><strong>Results:</strong> The occurence of more than 1 root canal in mandibular lateral and mandibular central was 41.2% and 40.4% respectively and all teeth had a single root. Type I (59.2%) was the most common type, followed by Type III (31.4%), Type II (5.8%), Type VII (2.1 %), Type VI (0.8%) and Type V (0.7%). Type IV and Type VIII were not observed. The root canal separation in two root canaI of central and lateral mandibular incisors was found in the middle third of the root in 65.4% and 74.6%, respectively. The incidence of Type III in males (39%) was higher than that of females (25.4%), while the incidences of Type I in females (67.7%) were significantly higher than that of males (48.3%).
