AimThe aim of this study is to determine the reliability of panoramic radiograph (PR) as a screening tool for the detection of calcified carotid atheroma (CCA) by comparing it with Doppler ultrasonography (DU) examination. A second aim was to evaluate the relationship among CCA, systemic diseases, smoking, and body mass index in an older population.Materials and methodsA total of 1,650 PRs of patients aged over 45 years (736 males and 914 females) were randomly selected. All the patients had been referred to the Faculty of Dentistry, Afyon Kocatepe University, Afyonkarahisar, Turkey, during 2013–2014 for routine PR screening. Medical data were collected from the archival records of the dental school. The patients were divided into two groups: Group A (study group), CCA findings were confirmed by DU (n=59); and Group B (control group), CCA findings were not confirmed by DU (n=34).ResultsOf the 1,650 individuals, 93 (5.63%) were detected to have CCA on PR. The population consisted of 43 males and 50 females with mean age of 59.84±10.92 years. No difference was determined in respect of CCA between the sexes (P=0.745). There was a significant difference between Group A and Group B in respect of hypertension (P=0.004). But there was no difference between Group A and Group B in respect of age (P=0.495), BMI (P=0.756), diabetes (P=0.168), and smoking (P=0.482) distribution.ConclusionAlthough PR cannot be used as an initial diagnostic method when searching for CCA, dentists should be aware of CCA on a routine PR, particularly in older patients who may also have the risk factors of obesity, diabetes mellitus, hypertension, and smoking. Recognizing of CCA especially in hypertensive patients could potentially increase the length and quality of life for individuals.

Güneydoğu Anadolu Bölgesi'nde yedi farklı dental anomalinin görülme sıklığı Amaç: Bu çalışmanın amacı, Güneydoğu Anadolu Bölgesinde yaşayan bireylerde yedi farklı dental anomalinin görülme sıklığının ve cinsiyetler arasındaki dental anomali görülme yatkınlıkların değerlendirilmesidir. Gereç ve Yöntemler: Çalışma Adıyaman Üniversitesi Dişhekimliği Fakültesi'ne ve Adıyaman Ağız ve Diş Sağlığı Merkezi'ne çeşitli nedenlerle müracat etmiş hastalardan rastgele seçilen 4256 hastaya ait panoramik radyografi görüntüleri üzerinde retrospektif olarak tasarlandı. Hastalara ait panoramik radyografi görüntüleri dental anomalilerin tespit edilmesi amacıyla 2 araştırmacı tarafından değerlendirildi. Çalışmada hastaların panoramik radyografi görüntüleri üzerinde tespit edilen, alt keser diş eksikliği, sürnümerer diş, ektopi, gömülü kalma, mikrodonti, taurodontism ve dilaserasyon olmak üzere 7 tip dental anomali cinsiyetler arası dağılımına göre istatistiksel olarak analiz edilmiştir Bulgular: En sık görülen anomali %4,2 oranıyla gömülü kalma olarak tespit edildi. Taurodontizm % 0,02 lik oranla en az görülen anomali olarak tespit edildi. Gömülü diş görülme sıklığı erkek bireylerde, kadınlara kıyasla istatistiksel olarak anlamlı derecede daha fazla bulunmuştur. Ektopik diş görülme oranı, erkeklerde kadınlara nazaran istatistiksel olarak anlamı derecede fazla bulunmuştur. Kadınlarda alt keser diş eksikliği görülme oranı, erkeklere göre istatistiksel olarak anlamlı derecede fazla bulunmuştur. Sonuç: Güneydoğu Anadolu Bölgesinde yaşayan bireylerde gömülü kalma, en sık rastlanılan anomali olarak karşımıza çıkmaktadır. Alt keser diş eksikliği kadınlarda daha fazla görülürken, gömülü diş ve ektopiye erkeklerde daha sık rastlanılmıştır. Bunun yanında, sürnümerer diş, dilaserasyon, taurodontizm ve mikrodonti gibi anomalilerin görülme sıklığı bakımından cinsiyetler arasında farklılık tespit edilmemiştir. Taurodontizm en az rastlanılan anomali olarak tespit edilmiştir.

BackgroundOral breathing causes many changes in the facial anatomical structures in adult patients. In this study we aimed to determine the effects of long-term oral breathing (>5 years) on the maxillary sinus volumes among adult male patients.Material/MethodsWe accessed medical records of 586 patients who had undergone cone beam computed tomography (CBCT) for any reason between September 2013 and April 2014. Patients who had undergone cone-beam dental volumetric tomography scans for any reason and who had answered a questionnaire about breathing were screened retrospectively. Cone beam dental volumetric tomography (I-Cat, Imaging Sciences International, Hatfield, PA, USA) was used to take the images of the maxillo-facial area at a setting of 120 kVp and 3.7 mA. This study involved male patients older than 21 years of age.ResultsThe study included a total of 239 male patients, of which 68 were oral breathers and 171 were nasal breathers. The mean age of the oral breathers was 48.4 years and that of the nasal breathers was 46.7 years and the difference was not statistically significant (p>0.05). The mean maxillary sinus volumes of the oral and nasal breathers were 9043.49±1987.90 and 10851.77±2769.37, respectively, and the difference in maxillary sinus volume between the 2 groups was statistically significant (p<0.001).ConclusionsThe volume of maxillary sinus in oral breathers (>5 years) was significantly lower than in nasal breathers, but it remains unclear whether this is due to malfunctioning of the nasal cavity or due to the underlying pathological condition.

BackgroundImplants that can be used in the prosthetic rehabilitation of full and partial edentulous patients are now frequently used due to advances in dentistry. Despite advanced methods of applications, failures and complications can still be seen. The aim of our study was to evaluate clinical prosthetic values and complications that occurred during 4-year follow-up in implant-supported restorations.Material/MethodsThis retrospective study included 40 patients who received oral rehabilitation with an implant-supported prosthesis. A total of 162 implants were placed: 99 in the maxilla and 63 in the mandible. The prosthetic and surgical data were recorded. Data including prosthetic complications and implant loss were recorded and statistically analyzed using Cox proportional hazard regression analysis.ResultsIn total, 159 implants (98.14%) survived, 3 implants (1.86%) failed, and 100% of the protheses were successful. There were 62 dental implants used as abutments for removable dentures and 97 for fixed dentures. The most frequent prosthetic complications after placement of an implant-supported prosthesis were loss of retention, mucositis, abutment screw loosening, and fracture. Patient satisfaction after prosthesis use was also evaluated, showing that satisfaction was systematically increased.ConclusionsTo minimize the frequency of complications, protocols must be established from diagnosis to the completion of treatment and follow-up of implant-supported prostheses, especially in terms of adequate technical steps and careful radiographic evaluation of the components.

BackgroundThe aim of the present study was to compare the effects of preemptive intravenous tenoxicam and methylprednisolone administrations on extraction of impacted third molars.Material/MethodsThis was a placebo-controlled, randomized, double-blind, clinical trial. A total of 60 adult patients ages 18–40 years with the complaints of impacted third molar teeth were included in the study.ResultsThe postoperative swelling ratios (p<0.05) and pain scores (p<0.05) were significantly better in both study groups than in the control group and there was no statistically significant difference between methylprednisolone and tenoxicam groups with regards to the edema and pain relief.ConclusionsPreoperative administration of 80 mg methylprednisolone achieves better control of trismus than tenoxicam without any significant differences in edema and pain control in impacted third molar teeth extraction.

KOPARAL, M.; IRTEGÜN, S.; ALAN, H.; DEVECI, E.; GÜLSÜN, B. & PEKTANÇ, G.Effects of melatonin on tibia bone defects in rats. Int. J. Morphol., 34(2):763-769, 2016. SUMMARY:The aim of this study was to evaluate the effects of melatonin healing in a tibial bone defect model in rats by means of histopathological and immunohistochemistry analysis. Twenty one male Wistar albino rats were used in this study. In each animal, bone defects (6 mm length ) were created in the tibias. The animals were divided into three groups. In group 1 control group (rats which tibial defects). Group 2 melatonin (10 mg/kg) + 14 days in the tibial defect group) was administered intraperitoneally to rats. Group 3 melatonin (10 mg/kg) + 28 days in the tibial defect group) was administered intraperitoneally to rats. Histopathological analysis of samples was performed to evaluate the process of osteoblastic activity, matrix formation, trabecular bone formation and myeloid tissue in bone defects. Immunohistochemical and immunoblot analysis demonstrated non-collagenous proteins (osteopontin and osteonectin) differences in tibial bone defects. The expression of osteopontin on tibia was increased by 14 days melatonin treatment. The expression of osteonectin on tibia was dramatically increased by 14 days melatonin treatment.
