The mandibular angle in osteoporotic men
Objectives: Osteoporosis induces the reduction of bone mass and screening for low bone mineral density (BMD) by dual-energy x-ray absorptiometry (DXA) has been the current gold standard test to determine osteoporosis. Panoramic radiography is widely used in dentistry for routine examination of jaws. The objective of this study was to determine the relationship between the mandibular angle (MA) values and the vertebral bone mineral density (v-BMD) in 20 osteoporotic men. Study design: In panoramic radiograms of osteoporotic men, the means were calculated for the mandibular angle values measured in the right and left mandible. v-BMD values were also calculated by manual analysis of DXA scans. The correlation between these variables was assessed. Results: A negatively significant correlation was found between the MA and v-BMD. Conclusions: The size of the mandibular angle decreases when osteoporosis increases. It is suggested that the mandibular angle may be useful in clinical dental practice to identify osteoporotic men with previously undetected low bone mineral density
Mucoepidermoid Carcinoma in a Minor Salivary Gland in a Child
Mucoepidermoid carcinoma (MEC), one of the most common salivary gland malignancies, is rare in children. MEC mainly occurs in the parotid gland, along with minor glands being the second common site, particularly in palate. Clinical, histological, and radiological findings of palatal MEC in a 12-year-old girl are presented with three-year follow-up. Pathologic lesions must be considered in differential diagnoses of intraoral asymptomatic lesions, and their detailed inspection should be taken into consideration
Florid cemento-osseous dysplasia : a case report
Cemento-osseous dysplasias are a group of disorders known to originate from periodontal ligament tissues and involve, essentially, the same pathological process. They are usually classified, depending on their extent and radiographic appearances, into three main groups: periapical (surrounds the periapical region of teeth and are bilateral), florid (sclerotic symmetrical masses) and focal (single lesion) cemental dysplasias. Florid cemento-osseous dysplasia clearly appears to be a form of bone and cemental dysplasia that is limited to jaws. Patients do not have laboratory or radiologic evidence of bone disease in other parts of the skeleton. For the asymptomatic patient, the best management consists of regular recall examinations with prophylaxis and reinforcement of good home hygiene care to control periodontal disease and prevent tooth lose. Management of the symptomatic patient is more difficult. At this stage, there is an inflammatory component to the disease and the process is basically a chronic osteomyelitis involving dysplastic bone and cementum. Antibiotics may be indicated but may not be effective. A case of florid cemento-osseous dysplasia occurring in a 47-year-old Caucasian female is reported which was rare in regard to race and sex
A systematic review on the correlation between skeletal and jawbone mineral density in osteoporotic subjects
Objectives: The aim of this systematic review was to assess whether the systemic skeletal reduction of bone mineral density (BMD) that characterizes osteoporotic subjects is also associated with a reduction of BMD in the jawbones. Material and methods: Two reviewers searched independently and in duplicate three databases up to May 2014 and assessed the risk of bias using a tailored version of the Newcastle-Ottawa scale (NOS). Only papers reporting either Pearson's correlation coefficient or Spearman's rank correlation coefficient between skeletal and jawbone mineral density in more than five osteoporotic subjects were selected. Results: From 1763 citations, 64 full-text papers were screened and five papers that met the inclusion criteria were included in the final analysis. None of the included studies complied with all NOS criteria, and as only two studies were eligible for meta-analysis, this was not performed. Conclusions: Only limited conclusions can be drawn from this systematic review, due to the small number of studies included, their heterogeneity, and their high risk of bias. Future studies that take into consideration both upper and lower jaws, that use the same technique to measure skeletal and jaw BMD (ideally dual-energy X-ray absorptiometry, DXA), and that account for confounding variables (such as medications/diseases affecting bone metabolism and demographics) are needed to provide more robust conclusions
Nazal kavite ve osteomeatal kompleks anatomik varyasyonları
Objectives: The maxillary sinuses are important anatomical structures for dental procedures in dentistry. The normal function of the sinuses is effective in the success of these dental procedures. The continuation of the normal functions of the paranasal sinuses, the maxillary and osteomeatal complex (OMC) has an important role. In this study, we aimed to investigate the frequency of osteomeatal complex anatomic variations with cone-beam computed tomography. Material and Methods: In this retrospective study, in cone-beam computed topographies of 280 patients (154 men, 126 women), anatomic variations of paranasal sinuses (deviated septum, inferior turbinate hypertrophy, concha bullosa, paradoxical middle turbinate, Agger nasi, Haller’s cell, Onodi cell, pneumatized uncinate process (uncinate bulla), pneumatized crista galli, pneumatized septum) were analyzed. Results: In our study, septal deviation 85%; inferior turbinate hypertrophy 48.6%; middle concha bullosa 40%; Agger nasi cells 28.6%; Haller’s cells 9.6%; pneumatized septum 4.6%; paradoxical middle turbinate 2.5%; pneumatized uncinate process 2.5%; pneumatized crista galli 1.4%; Onodi %1.1 were found. Conclusion: Variations of the osteomeatal complex due to the effect of the paranasal sinuses should be considered in maxillary dental implant planning. Keywords: Anatomic variation, osteomeatal complex, cone-beam computed tomography. ÖZETAmaç: Diş hekimliğinde maksiller sinüsler dental girişimler için önemli anatomik yapılardır. Bu girişimlerin başarısında sinüslerin normal fonksiyonları etkilidir. Maksiller ve diğer paranazal sinüslerin normal fonksiyonlarını sürdürmesinde osteomeatal kompleks (OMK) önemli bir role sahiptir. Bu çalışmada nazal fossa ve osteomeatal kompleks anatomik varyasyonlarının konik ışınlı bilgisayarlı tomografi (KIBT) ile sıklığının araştırılması amaçlandı. Gereç ve Yöntem: Bu retrospektif çalışmada 280 hastanın (154 erkek, 126 kadın) konik ışınlı bilgisayarlı tomografilerinde paranazal sinüslerin anatomik varyasyonları (Agger nazi hücresi, Haller hücresi, Onodi hücresi, orta konka bulloza, paradoksal orta konka, pnömatize unsinat proses (uncinate bulla), pnömatize krista galli, pnömatize septum, alt konka hipertrofisi, septum deviasyonu) incelendi. Bulgular: Çalışmamızda septum deviasyonu %85; alt konka hipertrofisi %48.6; orta konka bulloza %40; Agger nazi hücreleri %28.6; Haller hücreleri %9.6; pnömatize septum %4.6; paradoksal orta konka %2.5; unsinat proses pnömatizasyonu %2.5; pnömatize krista galli %1.4; Onodi hücresi %1.1 olarak bulundu. Sonuç: Osteomeatal kompleks varyasyonları paranasal sinüslere olan etkisi nedeniyle maksiller dental implant planlamalarında dikkate alınmalıdır
Evaluation of the morphological changes in the mandible for dentate and totally edentate elderly population using cone-beam computed tomography
The loss of teeth considerably modifies the mandibular shape. The aim of this study was to compare the morphological changes in the mandible for dentate and totally edentate elderly subjects using cone-beam computed tomography
Supernumerary tooth in the nose
The presence of a supernumerary tooth in the nose is an unusual phenomenon and a rare form of ectopic tooth eruption in the maxillofacial region. In this case, the patient was referred to the hospital with the complaint of severe headache. In the endoscopic examination, the supernumerary tooth crown was not covered with mucosa or granulation tissue. In the present study, the clinical and radiological diagnosis of a supernumerary tooth located in the nose is reported
