Assesment of accessory branches of canalis sinuosus on CBCT images

The aim of this study is to describe the presence, to reveal the frequency and characteristics of accessory canals (ACs) of the canalis sinuosus (CS) by cone beam computed tomography (CBCT). A total of 326 CBCT examinations were scanned retrospectively. The anatomical views were evaluated on sagittal, axial, coronal and cross sectional imaging. The following parameters were recorded: age, sex, presence or absence of ACs, location in relation to the adjacent teeth and distance to the nasal cavity floor (NCF), alveolar ridge crest (ARC) and buccal cortical bone (BCB), and incisive canal. All the collected data were statistically analyzed. 113 patients (34,7%); presented ACs in total 214 foramina of the sample. There were no statistically significant changes in the presence of ACs regarding age groups excluding 80-89 years. But there is a statistically significant difference regarding the frequency of ACs and the gender. The prevalence for male patients was higher than female patients. Curved-shape configuration of CS prevalence is found as 69,15%. The prevalence of vertical tracing is 26,16% and Y-shape configuration of CS prevalence is 4,67%. Diameter of the foramens of the CS branches was 1.30 mm. The mean distance of the AC to the NCF, BCB, and ARC were found 13,83 mm, 6,60 mm and 5,32 mm, respectively. In the anterior palatal region, ACs are mostly related to CS?s branches. So; knowing the course of CS branches in surgical planning and radiographic evaluations in this region is extremely important for preventing complications and avoiding misdiagnosis

Anterior stafne defect of the mandible

Stafne bone cavity is round or ovoid, well circumscribed radiolucency located at the lingual cortex of mandible, below the inferior alveolar canal, mostly near the angle. Anterior location of Stafne bone cavity is a unusual developmental anomaly and only 66 cases reported in the English literature. As a result of the localization of this formation, which is asymptomatic and diagnoses with routine radiographic examination, it may be confused with pathologies and may cause misdiagnosis. In this case report a Stafne bone cavity located in the mandibular incisor-canine region, which was found incidentally during radiographic examination cavity is presented with cone beam computed tomography and magnetic resonance images

Maxillary sinus fungus ball: a case report

Introduction: Sinus fungus ball is a non-invasive sinus disease and the incidence of this disease has increased in recent years. The aim of this case report was to present the radiographic and clinical findings of a patient who was diagnosed with a sinus fungus ball. Case Report: A 40-years-old female patient referred to Recep Tayyip Erdoğan University Faculty of Dentistry, Oral and Maxillofacial Radiology department with the complaint of pain in the head and orofacial region. Any dental reason that may cause the pain was not detected, however, a foreign body at the left maxillary sinus was seen on a panoramic radiograph taken from the patient. Then, cone-beam computed tomography images were obtained. These images revealed total opacification of the left maxillary sinus with calcified areas. Due to the complaint of the patient and clinical and radiographic findings magnetic resonance images were obtained with the initial diagnosis of possible fungal sinusitis. Magnetic resonance images supported this diagnosis. Upon this, the patient was operated and histopathological examination was made. The presence of fungus compatible with the Aspergillus type was confirmed with histopathologic examination. Conclusion: Dentists must be aware of maxillary sinus fungal infections in patients with facial pain

Taurodontism and C-shaped anatomy: is there an association?

WOS: 000560603900001PubMed: 32803678Objectives To evaluate the relation between taurodontism and C-shaped configuration, as well as the prevalence and classification according to sex, left/right position, and arc length in the mandibular premolar and molar teeth using cone beam computed tomography (CBCT). Methods the presence of taurodontism and C-shaped configuration were evaluated using CBCT scans and classified by two independent radiologists. the sex, location in the jaw (left-right), and mandibular arc length measurements were recorded. the Chi-square test was used to determine the presence of taurodontism and C-shape configuration according to sex, left/right location, and independent-samplettests were used to assess the relation between the arc length. Results the prevalence of taurodontism was significantly higher in the female population, whereas the C-shaped configuration was more frequent in males (p 0.05). Conclusions A high correlation was revealed between taurodontism and complicated C-shape canal configurations. Practitioners should be very careful about the presence of C-shape morphology in taurodontism treatment, and various types of C-shaped morphology ranging from coronal to the apical direction
