She had undergone an unsuccessful surgical procedure under local anesthesia performed by a general practitioner for removal impacted mandibuler third molar 1 week earlier. On clinical examination floor the tender to palpation. Panoramic periapical radiographs showed presence radiopaque mass similar that tooth root. Computed tomography scans were obtained...

The optic canal connects the anterior cranial fossa and orbit maintains nerve ophthalmic artery. Within extent of surgical approach region, risk iatrogenic injury neural vascular structures increases. aim this retrospective morphometric study is to investigate radiological anatomy orbita, canal, its surrounding using cone beam computed tomography (CBCT) scans in a group Turkish population. Cone images total 182 patients were evaluated by 2 observers. Anatomical parameters regarding orbita...

Halitosis is described as offensive breath caused by various factors such periodontal diseases, bacterial coating of tongue, systemic disorders and different types foods. Pseudohalitosis a situation that patients complain oral malodor even though they do not have odour. The purpose this study was to compare the relationships between social anxiety estimations both pseudohalitosis genuine halitosis cases. Liebowitz Social Anxiety Scale (LSAS) questionnaire regarding were applied 100...

The purpose of this in vitro study was to explore the radiopacity composite resins and bonding materials using film phosphor plates.Nine dental resin specimens human tooth slices were exposed together with an aluminium stepwedge plates. Eight dentin prepared a similar manner. Their on assessed transmission densitometer, plates digitally system's own software (Digora). Data analysed one-way analysis variance (ANOVA) post-hoc Tukey tests (P<.05). Film plate values compared simple regression...

To analyse specific volatile sulphur compound(VSC) levels in a group of chronic renal failure (CRF) patients and determine the relationship between these VSC organoleptic measurements, blood urea nitrogen (BUN) levels, dental periodontal conditions, salivary flow rate, tongue coating scores.One examiner performed measurements on fifty with CRF before after haemodialysis (HD) controls. DMFT CPITN indexes, scores, rates were measured. Comparisons using Mann-Whitney U, Wilcoxon signed-ranks,...

Description of the nasopalatine canal (NPC) is important for planning surgical treatment and comprehension morphology pathogenesis lesions that occur in anterior maxilla. The goal this study was to analyse dimensions anatomic characteristics NPC on cone-beam computed tomography (CBCT) scans, determine incidence anatomical variation; assess correlations these variables with age, gender, dental status.A total 320 individual CBCT images were included. Reformatted sagittal, coronal axial slices...

The purpose of this study was to compare the accuracy dental age estimation results obtained using Willems and Cameriere methods in a large Turkish sample. A further aim adapt Cameriere's regression equation population produce an updated model appropriate for children. Finally, we methods. group from two radiology department archives. total sample consisted 1878 children (972 boys, 906 girls) aged between five 15 years. were applied. method performed almost identically both sex groups....

Florid osseous dysplasia (FOD) is an uncommon, benign, cemento-osseous lesion of the jaws. The etiology FOD still unknown. It often asymptomatic and may be identified on routine dental radiographs. classic radiographic appearance amorphous, lobulated, mixed radiolucent/radiopaque masses cotton-wool with a sclerotic border in In our case was found incidentally periapical radiographs taken for restored teeth edentulous areas. For further detailed examination, panoramic radiograph cone-beam...

Abstract Background This study aimed to determine if there is a relationship between the presence of maxillary sinus pathology, nasal septum deviation and various lengths osteomeatal complex. Methods A total 223 CBCT images were included in study.
