Objectives: This purpose of this  case report is to explain the imaging characteristics of unilocular ameloblastoma in CBCT 3D radiograph. Case Report: A 32-year-old male patient came to the dentist complaining his painful right lower jaw over the past few days. Clinical examination showed extensive swelling in the posterior region of the right mandible to cause asymmetry at the inferior border of the mandibular corpus. Panoramic radiography showed radiolucent area in periapical mesial root of 46 tooth, extending to the right angular mandibular with a clearly demarcated shape,  and there was a root resorption of 47 tooth. CBCT 3D examination showed the presence of unilocular radiolucent lesion in a regular shape and a clear borderline, extending to the inferior border of the mandible and causing buccal-lingual cortical perforation accompanied with the resorption of adjacent 47 tooth. Conclusion: CBCT is a supporting radiography that may act as a more accurate diagnostic tool for the diagnosis of unique ameloblastoma lesions.

Desmoplastic ameloblastoma (DA) is one of the 6 histopathological subtypes of ameloblastoma. Hybrid lesions in which histopathologically conventional ameloblastoma coexists with areas of DA are rare. A 40-year-old male was referred to our hospital complaining of a swelling in the right premolar region of the mandible. A panoramic radiograph showed an area of radiolucency with a well-defined corticated border, whereas computed tomography revealed a unilocular radiolucent lesion and buccal expansion together with cortical perforation. The lesion was treated via enucleation and curettage of the marginal bone and fenestration. A histopathological examination showed a hybrid ameloblastoma with a pronounced desmoplastic pattern and follicular changes. The patient’s postoperative course has been favorable up to now, and no marked changes have been observed. We presented a case of hybrid ameloblastoma and reviewed the 36 reported cases of hybrid ameloblastoma that have been reported in the English literature.

Objectives: This case report is aimed to describe the features of CBCT in assessing tooth fracture. Case Report: A 50-year-old man came with complaints of discomfort in the right lower jaw area, especially when used for chewing. The results of the percussion test were positive. CBCT examination showed that there was a radiolucent image of the enamel in the middle of the crown root to the 1/3 apical of the mesial and distal roots of tooth 47 which resembled a fracture line. The fracture line also appears to have reached the pulp. In addition, there is a well-defined radiolucent appearance with an irregular shape along the root from the buccal to lingual alveolar crest and accompanied by a decrease in the alveolar crest. The fracture that occurred in this case was from the enamel to the apical and involved the pulp, thus the radiodiagnosis on tooth 47 was a complicated crown root fracture with lateral periodontal cyst. Conclusion: CBCT can be used to help identify tooth fractures by obtaining a more accurate and useful value in differentiating conditions associated with fractures. CBCT provides data on the size and length of the fracture line and the size of the lesion.

Relevance. The purpose of the research is to improve the functional diagnosis protocol in prosthodontic treatment of patients with TMD.Materials and methods. The optimal position of the mandible was determined for each patient by two methods: 1) TENS (transcutaneous electrical nerve stimulation) and 2) TENS + kinesiography. Then, the cone-beam computed tomography (CBCT) data were analyzed to determine the most physiological position of the condyles.Results. The analysis of the CT scans of patients without TMD (control group) showed that the right and left condyles occupy an anterior or central symmetrical position relative to the glenoid fossa. In the first and second methods, the condyles occupy an anterior or central position, which is the most optimal position of the lower jaw for the manufacturing of an occlusal stabilization splint. The statistical coefficients allowed us to determine that the second method was more accurate, since the obtained values were lower than those of the first method.Conclusion. Based on the results of this study, we can conclude that the improvement of the protocol, namely a new method for determining the optimal position of the mandible is more time-consuming, but more accurate and allows increasing the effectiveness at all stages of treatment of patients with this pathology.

The number of children swallowing magnetic foreign bodies has been a significantly high for the past decades, increasingly needing endoscopic or surgical interventions. Case report. In our observation, a 12-year-old girl swallowed magnetic balls from childrens designer 10 days prior to hospital admission. Foreign bodies (5 balls) were found during X-ray examination in the projection of the cecum. Conservative therapy carried out for 4 days had no success, thus colonoscopy was performed to remove foreign bodies. Foreign bodies were fixed to the intestinal wall, and attempts to separate them were unsuccessful. When a medical magnet was placed outside the body in the right iliac region, a chain of magnetic balls detached from the intestinal wall and made it possible to be captured in a trap loop and be removed. The girl avoided a laparotomy with an opening of the colon. Conclusion. External use of a medical magnet is effective for navigation and assistance during colonoscopic extraction when magnetic foreign bodies are found in the colon.

ABSTRACTIdiopathic root resorption (IRR) is an infrequent condition that is usually found as an accidental finding on radiography. A significant number of cases of IRR in permanent dentition have been presented but are rarely reported in primary dentition. The aim of this case report is to present a case of localized IRR in a 7-year-old boy. The patient was referred because of increased mobility of the left mandibular primary second molar. On radiographic evaluation, severe root resorption of that tooth, and mild root resorption of the right mandibular primary second molar were evident; the patient was caries-free. The left affected tooth was lost, and after placing a band and loop space maintainer, the patient was followed for 18 months. A patient with an abnormal pattern of root resorption, especially in the primary dentition, should alert the clinician to rule out the known important local and systemic factors. The exact causes of and treatments for IRR continue to be discovered.

This case report describes a rare form of malignant bone tumor in an 8-year-old Labrador retriever. This dog initially presented for evaluation of a right distal humeral mass. Radiographs of the right elbow and thorax were performed, revealing a smooth mineralized mass adjacent to the lateral aspect of the distal humerus and a 5mm pulmonary nodule. Computed tomography (CT) of the humerus and thorax showed a smooth mineralized lesion adjacent to the lateral humeral epicondyle, and a right cranial lung lobe nodule with a thin mineral rim. Surgical biopsies of both lesions were diagnostic for parosteal osteosarcoma (POSA). The dog was then treated with stereotactic body radiation therapy (SBRT) which controlled the dog's discomfort for 14 months until he became progressively painful and subsequently had his right forelimb amputated. This case report is the first to document the CT imaging characteristics of a metastatic appendicular POSA in a dog and the first dog described with POSA treated with SBRT. The dog lived for 623 days after histopathologic diagnosis and 849 days after initial presentation with pulmonary metastatic disease.

Thing. The optical density of the lower jaw in the frontal part of female patients was studied, age-related differences in the optical density of the lower jaw were revealed. The aim is to reveal the variability of the values of optical density of the lower jaw in the anterior region in female patients. Methodology. Computed tomograms of the lower jaws of 26 patients were analyzed. The optical density of the bone was assessed using the method of computer densitometry in Hounsfield arbitrary units, measurements were carried out in the area of the root apexes of the lower canines. Statistical analysis was carried out using Microsoft Excel, Windows 9. Results. In 84.6 % of cases, the optical density of bone tissue in the area of 3.3 and 4.3 teeth is within the same class according to the Misch classification. In this group, 72.7 % of patients had class D2, 18.18 ― D1, 9 ― D3; in 15.4 %, the bone density on the right and left sides of the mandible belongs to D2 and D3. The optical density between two relatively symmetrical points is in the range from 2 to 238 units, between the right and left sides it is 129.66 HU. In the group of 30―39 (n = 6) years, in 50 % of cases, bone density belongs to class D2, in 33.33 ― D1, in 16.66 ― D3; 40―49 (n = 8) years in 87.5 % of cases ― D2, in 12.5 ― D1; 50―59 (n = 6) years at 50 % ― D2 and at 50 ― D3; 60―68 (n = 6) years at 50 % ― D2 and at 50 ― D3. Conclusions. With increasing age of patients, there is a decrease in bone density in the lower jaw in the canine area.

CONTEXT: Spontaneous cholecystocutaneous abscess or fistula is an extremely uncommon complication secondary to cholecystitis. Over the past 50 years fewer than 20 cases of spontaneous cholecystocutaneous fistulas have been described in the medical literature. We here report a case of subcutaneous gallstone as a rare clinical presentation of the already uncommon cholecystocutaneous fistula. CASE REPORT: An 81-year-old man presented with a large subcutaneous abscess in the right subcostal area with surrounding cellulitis and crepitus. An abdominal computed tomography scan showed two subcutaneous gallstones and communication between the abscess and the gallbladder. Cholecystectomy was performed and the abdominal wall abscess was drained externally. This case report demonstrates that maintaining a high degree of suspicion of this rare entity is helpful in achieving correct preoperative diagnosis, and that computed tomography scan should be performed in all cases of unexplained abdominal wall suppuration or cellulitis.
