    Objective:The purpose of this study was to compare the treatment duration and fees of Angle Class I, II, and III malocclusions.Methods:In this retrospective study, the samples were selected from the files of 450 patients treated at the Department of Orthodontics, İnönü University. The files of patients whose treatments were completed as planned were included in the study. In total, 387 patients (137 males and 250 females) met this criterion (mean age: 14.65 years). Patients were divided into three groups: treatment duration less than 20 months (group A), between 20–30 months (group B), and more than 30 months (group C). Analysis of variance (ANOVA) and t-tests were conducted to determine the difference in treatment duration between the groups and sexes.Results:From the 387 patients, 78 (20.2%) had Class I, 254 (65.6%) had Class II, and 55 (14.2%) had Class III malocclusion. The average treatment duration was 27.82 months (males: 31.82 months, females: 29.33 months). There were no statistically significant differences between the sexes according to the treatment duration. The average treatment duration according to malocclusions was 26.24 months for Class I, 28.22 months for Class II, and 28.21 months for Class III. The distribution of the groups according to treatment duration was as follows: Group A: 72 (18.6%), Group B: 173 (44.7%), and Group C: 142 (36.7%) patients. The relationship between the treatment durations and Angle classifications was not statistically significant (p=0.216).Conclusion:This study showed that there were severe anomalies and problematic malformations within each Angle classification because no statistically significant difference among the malocclusion classes in terms of the duration of treatment was found. Therefore, besides the anomaly type, the treatment duration and effort put into the work should also be taken into consideration in determining the treatment charge

    Objective:The aim of this study was to assess the reliability of cephalometric analysis using 3 different digital analysis programs.Methods:For this study, a dry human skull with the entire mandible, maxilla, and teeth was used. Fifteen lateral and 15 posteroanterior cephalometric digital images were taken by rotating the skull from 0° to ±14° at 2° intervals to obtain different images. Two researchers located the landmarks on the digital images independently using 3 computer-assisted analysis programs, Dolphin Image Software (Dolphin Imaging and Management Solutions), Quick Ceph Image (Quick Ceph Systems Inc), and Vistadent OC (GAC Int Inc). Following the first measurements (T1), all landmarks were relocated within a 2-week interval (T2) by each examiner. A paired and the independent Student t tests were used for intraexaminer and interexaminer measurements, and Pearson correlations were obtained. Intraclass correlation coefficients (ICC) were calculated to determine intraexaminer repeatability.Results:For the repeated measurements, mean differences were statistically insignificant, and high correlations for the repeated measurements were found, and the intraexaminer correlations were significant for each examiner (p<.001). When the interexaminer correlations of 3 analyses were compared, interexaminer correlations showed high consistency and the lowest Pearson r value was the same angular measurement (S ant-n-ss) (p<.001). ICC values demonstrated high intraexaminer repeatability. The highest value of ICC was the mandibular body length (go-me) for both examiners (p<.001).Conclusion:The 3 tested analysis programs may be accepted as reliable for clinical use

    Aim:The purpose of this study was to evaluate the antibacterial effects of 3 different fluoride-releasing orthodontic composites using a direct contact test (DCT).Materials and Methods:The antibacterial properties of fluoride releasing orthodontic composites were evaluated with the DCT. For the DCT, wells (n=8) of 96-microtitre plates were coated with the tested bonding adhesives [Transbond Plus (3M Unitek, Monrovia, USA) Light Bond (Reliance Ortho Prod. Inc. Itasca, IL, USA) Kurasper F (Kuraray Medical Inc. Okayama, Japan)]. Kalzinol (Zinc-Oxide Eugenol Cement) (Dentsply, Konstanz, Germany was used as a positive control material. A Streptococcus mutans suspension was placed on the surface of each specimen for 1 hour at 37°C. Bacterial growth was monitored for 16 hours with a temperature-controlled microplate spectrophotometer. The kinetics of the outgrowth in each well was recorded continuously at 650 nm every 30 minutes. The data were analyzed by one-way ANOVA, as well as by Tamhane's T2 multiple comparison test. The level of significance was determined as P < 0.05.Results:The evaluation of the results of the DCT revealed that there were statistically significant differences between the four groups (F= 156,951, P= 0.000). The control material (Kalzinol) showed complete inhibition of bacterial growth (mean 0.01 ±0.05). The multiple comparison test indicated that there were no significant difference in bacterial growth between Kalzinol and Transbond Plus (mean 0.12±0.17) (P= 0.509).. Kurasper F (mean 0.73±0.06) and Light Bond (mean 0.85±0.02) showed statistically significant differences (P= 0.000) compared to Kalzinol.Conclusion:Transbond Plus showed marked antibacterial effects

    Objective:For prolonged use in the oral cavity, orthodontic band adhesives should have certain physical properties to ensure the best clinical performance. The degree of conversion (DC) of orthodontic band adhesives has been found to affect their mechanical properties. The aim of this study was to investigate the effects of time delay on the DC of orthodontic band adhesives.Materials and Methods:Fourier-transform infrared spectroscopy was used to evaluate the DC of 3 adhesives (Bisco Ortho Band Paste LC, Multi Cure Glass Ionomer Band Cement, Transbond Plus Light Cure Band Adhesive) immediately after they had been polymerized and stored in artificial saliva at 37 ± 1°C for 30 days. Thirty disc-shaped specimens (10 for each adhesive) were fabricated in Teflon molds (6.0 × 1.0 mm). The samples for each adhesive were divided further into 2 groups (n=5).Results:The DC was significantly influenced by the band adhesive type (p < 0.05), and there were significant differences among band adhesive types for the DC after 30 days.Conclusion:The value of the DC could change with time delay

    Memenin inflamatuar psödotümörü (MIP) çok nadir bir durumdur. Lite- ratürde sınırlı sayıda olgu bildirilmiştir. Patogenezi tartışmalı bir konudur. Memenin inflamatuvar psödotümörü ön tanısıyla rezeksiyon yapılan 65 yaşında bir kadın hasta irdelendi. Sağ memesinde ağrısız kitle yakınması ile kliniğimize başvurdu. Görüntüleme eşliğinde tru-cut biyopsi yapıldı. Tru- cut biyopsi sonrası patolojik bulgular inflamatuvar psödotümörle uyumluy- du. Lokal eksizyon işelemi uygulandı. Yirmi dört aylık takiplerinde nüks saptanmadı.Inflammatory pseudotumor of the breast (IPB) is a very rare condition. Literature reports a limited number of cases. Its pathogenesis is also a con- troversial issue. Within the scope of our study, a 65-year-old female patient, who had resection because of inflammatory pseudotumor of the breast, was evaluated. The patient presented to our clinic with complaints of a painless mass in her right breast. Imaging guided tru-cut biopsy was performed. The pathological findings following the tru-cut biopsy were consistent with inflammatory pseudotumor. Local excision was performed. There was no recurrence during the 24-month follow-ups

    Primary neuroendocrine carcinoma of the breast is extremely rare. More than 97% of neuroendocrine tumors occur in the gastrointestinal and respiratory tracts. Three cases that have been operated in our clinic and had a diagnosis of primary neuroendocrine carcinoma of the breast were assessed, along with literature data. Histopathological diagnoses were obtained by preoperative core needle biopsy. Breast-conserving surgery was performed in two cases, and modified radical mastectomy in one. In all cases, immunohistochemical studies were positive for neuron-specific enolase and synaptophysin. All patients received adjuvant chemotherapy (CT) and one patient received additional radiotherapy (RT). Recurrence or distant metastasis was not detected during long-term follow-up after surgery.Memenin primer nöroendokrin karsinomları oldukça nadirdir. Nöroendokrin tumorlerin %97’den fazlası gastrointestinal ve solunum sisteminde ortaya çıkar. Kliniğimizde memenin primer nöroendokrin karsinomu nedeniyle opere edilen üç olgu literatür eşliğinde değerlendirildi. Ameliyat öncesi histopatolojik tanılar kalın iğne biyopsisi ile kondu. İki olguya meme koruyucu cerrahi, birine de modifiye radikal mastektomi işlemi uygulandı. Tüm olgularda immünhistokimyasal çalışmalarda nöron spesifik enolaz ve sinaptofizin pozitifliği görüldü. Olguların tümüne adjuvan tedavide kemoterapi (KT) verilmiş olup bir olguda ayrıca radyoterapi (RT) uygulandı. Ameliyat sonrası uzun dönem takiplerinde nüks ya da uzak metastaz saptanmadı
