Efficacy of EDDY, passive ultrasonic irrigation and manual irrigation on the removal of orange-brown precipitate

Aim: The aim of this study was to compare the different irrigation activation techniques for removing the orange-precipitate formed after irrigation with sodium hypochlorite (NaOCl) and chlorhexidine (CHX). Methodology: In total, 45-single rooted extracted human teeth were prepared with the ProTaper NEXT rotary system. 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. Results: 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> 0.05). Conclusions: 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. How to cite this article: İnce Yusufoglu S, Keskin NB.

The comparison of the efficacy of Alveogyl, 0.8% Hyaluronic acid, and 0.2% Chlorhexidine Digluconate in alveolar osteitis

Aim: The aim of this study was to compare the efficacy of Alveogyl, 0.8% hyaluronic acid (HA), and 0.2% chlorhexidine digluconate (CHX) gel in reducing pain and improving clinical signs and symptoms of alveolar osteitis. Methodology: The clinical data of patients treated for alveolar osteitis between 01/01/2015 and 01/01/2019 were retrieved for this study. 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. Results: Sixty-seven patients were included in the study. There was no statistically significant difference between groups in all control evaluations (p>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<0.05). No other significant changes in clinical signs and symptoms were observed among groups. Conclusion: 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. How to cite this article: Dereci Ö, Görkem T, Koşar YÇ.

Examination of root canal morphology of teeth affected by Molar Incisor Hypomineralization (MIH): Frequency of accessory canals

Aim: The aim of this study was to investigate the incidence of the presence of accessory canals in the root canal of the maxillary first molar teeth affected by Molar Incisor Hypomineralization (MIH). Methodology: A total of 12 maxillary first molar teeth affected by MIH were obtained from 10 children aged from 10 to 12 years. The frequency of the presence of accessory canals was examined by using microcomputed tomography and 3D image software. Results: Accessory canals were observed in the mesiobuccal (MB) canal in all of the samples with a statistically significant difference.(p<0.05) It was observed that the accessory canals were mostly in communication with the canals in the MB root and that furcal accessory canals were found in 10 (83.33%) teeth. The incidence of accessory canals was 75% in the distobuccal (DB) canal and it was 66.66% in the palatal (P) canal. Conclusion: The incidence of the presence of accessory canals in DB and P canals and furcation is higher in the teeth affected by MIH. How to cite this article: Özükoç C.

Evaluation of the effectiveness of reciprocal and conventional shaping systems and EDDY and CanalBrush activation systems in calcium hydroxide removal

Aim: To compare the effectiveness of two preparation systems and two irrigation techniques in calcium hydroxide removal from straight root canals. Methodology: Forty-four mandibular premolar teeth were included in this study. The teeth were filled with a calcium hydroxide-based paste and randomly divided into two different preparation groups (Reciproc 50 (R50; VDW, Munich, Germany and ProTaper Universal F5 (PTU; Dentsply Maillefer, Ballaigues, Switzerland). Subsequently, the groups were divided into two subgroups and irrigated using EDDY (VDW, Munich, Germany) and CanalBrush (CB; Roeko, Langenau, Germany) irrigation activation systems. The percentage of calcium hydroxide removed from the canal walls was analyzed using a dental operating microscope (DOM) at 25× magnification. An independent samples t -test, a Mann–Whitney U, Wilcoxon’s tests were used for statistical analysis. Results: There was no significant difference in calcium hydroxide removal throughout the root canal using the R50 and PTU F5 preparation systems ( P = 0.847). Both activation systems significantly increased the amount of calcium hydroxide removed from the root canal. Conclusions: EDDY and CB significantly improved calcium hydroxide removal. There was no significant difference between the R50 and PTU F5 systems in calcium hydroxide removal. How to cite this article: Keskin NB, İnce Yusufoğlu S.

The chemical evaluation of different dental graft materials by energy dispersive X-ray spectrometry technique

Aim: The physicochemical properties of dental graft materials are very important because they strongly influence the bone regeneration capabilities of biomaterials. 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. Methodology: 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. Results: 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. Conclusion: 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.

Comparison of the incidence of post-operative pain after low-level laser therapy between single- and multi-visit root canal treatments for chronic apical periodontitis: A prospective randomized clinical trial

Aim: The aim of this clinical study was to evaluate the effect of low-level laser therapy, used in conjunction with conventional canal disinfection techniques, on post-operative pain after single- and multi-visit root canal treatments for chronic apical periodontitis. Methodology: 100 volunteers were randomly divided into 4 groups. The main inclusion criteria were radiographic evidence of apical periodontitis (minimum size of 2.0 × 2.0 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. Results: There was no statistically significant difference between the groups in terms of post-operative pain at any time during the observation period (p > .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. Conclusion: 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.

Technical and biological causes of periapical surgery: Retrospective analysis of 301 apical surgical cases

Aim: Endodontic surgery is a treatment for persistent peri-radicular pathological conditions that do not improve after endodontic treatment. 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. Methodology: 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. Results: 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 %. 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 %). 37.5% of cases undergoing periapical surgery, the diameter of the cystic lesion was 10mm or more. Conclusion: 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. How to cite this article: Ekici Ö.

Assessment of root canal anatomy of mandibular incisors using cone-beam computed tomography in a Turkish subpopulation Root Canal Anatomy of Mandibular Incisors Using CBCT

Aim: The achievement of root canal treatment is influenced by the status of the root canals. 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. Methodology: 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. Results: 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%). The prevalence of second canals in mandibular incisors were detected more frequently in men than in women. Conclusion: The prevalence of second canal in total mandibular incisors is 40.8% (Type III was observed the most frequently). CBCT is an appropriate method for identifying of canal morphologies of mandibular incisors. How to cite this article: Çoban Kanyılmaz AN, Okumuş Ö, Sunay H.
