The purpose of this study was to examine the possible effect of extremely low-frequency electromagnetic fields (ELF-EMFs), from a high-voltage source, on rat teeth in terms of changes in trace elements (TEs) and the effect of antioxidants (melatonin [MLT] and Ganoderma lucidum [GL]) in counteracting these effects. We used adult male Wistar albino rats with a mean weight of 250–300 g and divided the rats into eight groups. The groups were subjected to an ELF-EMF that was applied with a high-voltage line for 8 hours/day for 26 days (Groups I, II, and III) or 52 days (Groups V, VI, and VII). Groups IV and VIII were the 26- and 52-day control/sham groups, respectively. Groups II and VI were treated with GL, and Groups III and VII were treated with MLT. MLT and GL were administered daily based on the weight of the animals and appropriate standards. At the end of the study, the rats were euthanized, and their anterior teeth were extracted. The teeth were preserved in pure water before evaluating the major TEs. At the end of the study, TE concentrations (in mg/kg) were assessed in the control and test groups. Compared with Group V, statistically significant differences in the concentrations of zinc (Zn) and strontium (Sr) were found for Group VII (ELF-EMF + MLT) (P<0.05). Therefore, ELF-EMF exposure can change the content of certain TEs in teeth and, after administering MLT and GL, the values of some of the TEs return to normal.

Background One of the aims of endodontic treatment is to control preoperative and postoperative pain. The present study evaluated the effects of local and systemic ibuprofen on postoperative pain. It aimed to determine the most effective method for relieving postoperative pain due to chemomechanical preparation. Material/Methods Ninety patients with symptomatic apical periodontitis were randomly assigned to local ibuprofen, systemic ibuprofen, and control groups (n=30 each). Chemomechanical preparations were performed using a ProTaper Universal Ni-Ti rotary file under 2.5% sodium hypochlorite and 17% ethylenediaminetetraacetic acid irrigation. After the root canals were dried with sterile paper points, while Odontocide paste was applied into the root canals of the patients in the local ibuprofen group, calcium hydroxide paste was applied into the root canals of the patients in the systemic ibuprofen and control groups. Following completion of the endodontic treatment procedure, 200 mg ibuprofen was prescribed to patients in the systemic ibuprofen group. Friedman and Wilcoxon tests were used for statistical analysis. Results Posttreatment pain scores were recorded at 6, 12, 24, and 48 h using a visual analogue scale. Although there were no significant differences between the local ibuprofen group (Odontocide) and the control group (Ultracal) ( P >0.05), pain scores in the systemic group (Ultracal+200 mg ibuprofen) were significantly lower than those in the other 2 groups ( P <0.05). Conclusions These results indicate that systemic administration of ibuprofen is effective for postoperative pain relief.

Aim: In our country, the stress experienced by physicians due to their working conditions and intense workload plays a role in the formation of medical errors, therefore, physicians want to protect themselves from litigation processes with defensive medicine practices. The aim of our study is to evaluate the effects of defensive medicine practices on health service delivery. Material and Method: In our study, the knowledge and attitudes of a total of 175 dentists working in Dicle University Faculty of Dentistry and Diyarbakir Oral and Dental Health Hospital and its affiliated centers about defensive medicine practices, age, physician (service) duration, gender, institution, title and specialty areas, if any, the relationship was examined using the knowledge level measurement questionnaire. While performing statistical analysis, Chi-square Test was used for comparisons. Result: It was observed that 32% of the physicians in the 26-40 age group, who constitute the vast majority (71.4%) of the participants in the study, were not aware of the concept of defensive medicine. It was found that 36.6% of the participants, 84.4% of those with 1-5 years of medical experience, and 83.3% of the specialty students with the largest share, with the largest share, did not know this concept at all. Conclusion: It is found that most of the physicians do not have the necessary knowledge about medical errors and malpractice. While the level of knowledge is increased through in-service training programs, seminars and conferences about malpractice, medical errors, defensive medicine practices, the experience of experienced physicians can be used in preventing and solving problems.

Çift sinüs septa %5 olarak görülmüştür. Bu yüzdelik değerler; p&lt;0,05 için istatistiksel olarak anlamlı kabul edilmiştir.

Bifid mandibular kondil (BMK) diğer ismiyle çift başlı kondil, mandibular kondil başının ikizleşmesi ile karakterize nadir görülen bir durumdur. BMK etiyolojisi tam olarak bilinmemekle beraber gelişimsel ya da travma sonucu oluşabilmektedir. Bu çalışmanın amacı, bifid mandibular kondilin (BMK) Güneydoğu Anadolu popülasyonundaki prevalansının konik ışınlı bilgisayarlı tomografi (KIBT) ile retrospektif olarak değerlendirilmesidir. Gereç ve Yöntemler: Bu retrospektif çalışmada, 2015-2020 yılları arasında Dicle Üniversitesi Diş Hekimliği Fakültesi, Ağız, Diş ve Çene Cerrahisi ABD'ye çeşitli nedenlerle başvuran 650 (350 kadın, 300 erkek) hastaya ait KIBT görüntüleri değerlendirildi. BMK tespit edilen vakalara ait yaş, cinsiyet ve yön (sağ-sol) açısından elde edilen tüm veriler kaydedildi ve istatistiksel olarak analiz edilerek, görülme sıklıkları belirlendi. Bulgular: Yaş ortalaması 40 olan 18-65 yaş aralığındaki 650 hastanın 35'inde (21 kadın, 14 erkek) toplam 40 tane BMK tespit edildi. BMK, 5 hastada bilateral; 30 (17 sağ, 13 sol) hastada ise unilateral olarak görüldü. BMK görülme sıklığı kadınlarda %6, erkeklerde %4,6 olarak tespit edildi. Ayrıca yaş gruplarında BMK'nin pozitif veya negatif olması yönünde, görülme sıklıklarında istatistiksel olarak anlamlı bir fark görülmedi. Sonuç: Çalışmamızda BMK prevalansı, Güneydoğu Anadolu popülasyonunun %5,38'inde görülmüş olup; kadınlarda ve sağ tarafta daha sık saptandı.

Although the etiology of BMC is not known exactly, it may occur as a result of developmental or trauma. The aim of this study was to evaluate the prevalence of bifid mandibular condyle (BMC) in Southeastern Anatolia of population by using cone-beam computed tomography (CBCT). Material and Methods: In this retrospective study, CBCT scans of 650 (350 females, 300 males) patients who referred to Dicle University Faculty of Dentistry, Department of Oral and Maxillofacial Surgery between 2015 and 2020 were evaluated. BMC cases were analyzed according to the patients age, gender and direction (right-left) their frequencies were determined statistically. Results: A total of 40 BMCs were detected in 35 (21 female, 14 male) of 650 patients aged 18-65 years, with a mean age of 40. BMC, bilateral in 5 patients; it was seen unilaterally in 30 (17 right, 13 left) patients.The incidence of BMC was 6% in women and 4.6% in men. In addition, there was no statistically significant difference in the incidence of positive or negative BMC in age groups. Conclusion: In our study, the prevalence of BMC was seen in 5.38% of the Southeastern Anatolian population, and it was more common in women and on the right side. In addition, it ...
