A 58-year-old male patient was referred for a panoramic radiograph after having presented with a hard swelling of the right mandible. Panoramic radiographic examination (Fig. 1) demonstrated multiples dental anomalies and variable bone densities in both jaws prompting clinicians to “dig” further. Teeth 17, 12, 11, 26 and 27 were missing. Teeth 13, 23, 24, 25, 38, 34, 33 and 43 were unerupted. An unerupted supernumerary left mandibular molar appeared in the region of the mandibular coronoid process. Multiple, small, well-defined radiopacities of density comparable to odontogenic material were evident in the anterior maxilla and mandible. These opacities often demonstrated radiolucent borders consistent with the finding of multiple odontomas. Both jaws demonstrated variable bone density. Cottonwool like opacities partially blending into adjacent trabeculae were evident in the mandible and maxilla posteriorly. The contour of the inferior border of the mandible bilaterally in proximity to the angle was irregular with multiple, well-defined, smooth, lobulated homogenous radiopacities suggestive of osteomas. The radiographic features of multiple osteomas, odontomas, variable bone density, supernumerary and unerupted teeth warranted the referral of the patient for gastroenterological investigation to exclude Gardner Syndrome.

Abstract Introduction/Objective Adenomatoid odontogenic tumor (AOT) is an uncommon benign odontogenic tumor representing 3 to 7% of all odontogenic tumors. This tumor was first reported as adeno-ameloblastoma by Bernier and Tiecke in 1950 as it was initially assumed to be a type of ameloblastoma. In 1969, Philipsen and Bern proposed the term adenomatoid odontogenic tumor which was subsequently adopted by WHO and became the accepted terminology for this tumor. AOT is classified as a tumor of odontogenic epithelium but occasionally abnormal hard tissues consistent with dentinoid material may also be present as part of the tumor. AOT tends to occur in younger patients and 50% of the cases are diagnosed in teenagers. It occurs twice as commonly in females and frequently involves the anterior maxilla. Radiographically, AOT can appear as a radiolucent or mixed lucent-opaque lesion and may be associated with an impacted tooth. Methods/Case Report We report two unusually large expansile lesions of AOT that presented in the mandible. In the first case, the tumor presented as an expansile radiolucent lesion involving the right posterior mandible in a 32 year old female. In the second case, the tumor presented as an expansile mixed lucent-opaque lesion involving the left anterior mandible in a 21 year old female. The clinical presentation, radiographic and imaging findings, histopathologic features and treatment of these two cases will be discussed. The recommended treatment for AOT is surgical excision. The prognosis is good as this tumor seldom recurs after excision. Results (if a Case Study enter NA) NA Conclusion AOT is considered to be a non-aggressive, non-invasive and slow growing benign neoplasm. It is usually discovered on routine radiographic examination as the lesion is usually small and asymptomatic at the time of diagnosis but occasional cases that are larger in size have been reported in the literature.

Objectives: To evaluate the impact of movement and motion-artefact correction systems on CBCT image quality and interpretability of simulated diagnostic tasks for aligned and lateral-offset detectors. Methods: A human skull simulating three diagnostic tasks (implant planning in the anterior maxilla, implant planning in the left-side-mandible and mandibular molar furcation assessment in the right-side-mandible) was mounted on a robot performing six movement types. Four CBCT units were used: Cranex 3Dx (CRA), Ortophos SL (ORT), Promax 3D Mid (PRO), and X1. Protocols were tested with aligned (CRA, ORT, PRO, and X1) and lateral-offset (CRA and PRO) detectors and two motion-artefact correction systems (PRO and X1). Movements were performed at one moment-in-time (t1), for units with an aligned detector, and three moments-in-time (t1-first-half of the acquisition, t2-second-half, t3-both) for the units with a lateral-offset detector. 98 volumes were acquired. Images were scored by three observers, blinded to the unit and presence of movement, for motion-related stripe artefacts, overall unsharpness, and interpretability. Fleiss’ κ was used to assess interobserver agreement. Results: Interobserver agreement was substantial for all parameters (0.66–0.68). For aligned detectors, in all diagnostic tasks a motion-artefact correction system influenced image interpretability. For lateral-offset detectors, the interpretability varied according to the unit and moment-in-time, in which the movement was performed. PRO motion-artefact correction system was less effective for the offset detector than its aligned counterpart. Conclusion: Motion-artefact correction systems enhanced image quality and interpretability for units with aligned detectors but were less effective for those with lateral-offset detectors.

Case Report: A male 24 years came to the Dentomaxillofacial Radiology Installation, Faculty of Dentistry Dental Hospital Universitas Padjajaran  referred for radiographic examination from the Periodontics Department. The patient will be paired dental implants in the second premolar in the right mandible. Patients had no inflammation and pain. The patient then were take radiography examinations as indicated dental implant, that were periapical, panoramic and CBCT, then one of the radiographic examination was done, the panoramic which shows radiopaque, well-defined, rounded irregularly shaped lesion with a diameter of approximately 6 mm, which is located around apical first premolar teeth in the right mandible. Mandible first premolar is still vital. Conclusion: Dense bone Island is an increased bone density that occurs in the maxilla or mandible especially around the root of a tooth, and is often asymptomatic. Cases that occur in these patients have no clinical complaints either before or after the installation of dental implant.

Objectives: The aim of this case report is to provide further information on the radiological features of a solid type ameloblastoma suspected on a 3D CBCT radiograph. Case Report: A patient came referred by a dentist for CBCT 3D radiography with suspected clinical diagnosis of a maxillary anterior dentigerous cyst. The results of the CBCT 3D radiographic examination showed a radiointermediate with a clear border on the anterior maxilla and in the right maxillary sinus accompanied by the impact of two supernumerary teeth. Radiological features of ameloblastoma generally show a multilocular radiolucent picture and have a radiopaque septa bone internal structure such as a soap bubble appearance or honey combed appearance. This case showed a clearly demarcated radiointermediate image because a solid type ameloblastoma contains tissue that is histologically formed from cells hat are follicular or plexiform and derived from the results of a degenerative process at the center of the Langerhans islands. Conclusion: Radiographic examination with high modality such as CBCT 3D is very important in helping to establish a diagnosis, especially for cases that sometimes show differences in the radiographs.

Compound Odontoma

Introduction. Odontomas are the most common type of odontogenic tumors and generally they are asymptomatic. These tumors are formed from enamel and dentin, and can have variable amounts of cement and pulp tissues. According to radiographic, microscopic, and clinical features, two types of odontomas are recognized: Complex and compound odontomas. Complex odontomas occur mostly in the posterior part of the mandible and compound odontomas in the anterior maxilla. Case Report. A young girl patient, 9 years old came to Department of Oral and Maxillofacial Surgery with a slow growing and asymptomatic swelling in her left posterior mandible for 5 years in his history taking. The panoramic radiograph show  a radioopacity and radiolucent lesion at the lower second molar region, with well-corticated limits. An insisional biopsi   confirmed  as compound odontoma. The surgery  performed with simple enucleation and curettage under general anaesthesia. Discussion. Compound odontomas are usually located in the anterior maxilla, over the crowns of unerupted teeth, or between the roots of erupted teeth. In this case report, Compound odontomas are found in the posterior mandible. Conclusion. Compound odontomas in the posterior mandible is a rare. The treatment of odontomas depends on the size of the lesion. The early diagnosis, the treatment of choice is conservative surgical enucleation and curettage and prognosis is excellent.

Ameloblastic fibroma is an uncommon mixed neoplasm of odontogenic origin with a relative frequency between 1.5 – 4.5%. It can occur either in the mandible or maxilla, but predominantly seen in the posterior region of the mandible. It occurs in the first two decades of life. Most of the times it is associated with tooth enclosure, causing a delay in eruption or altering the dental eruption sequence. The common clinical manifestation is a slow growing painless swelling and is detected during routine radiographic examination. There is controversy in the mode of treatment, whether conservative or aggressive. Here we reported a 38 year old male patient referred for evaluation of painless swelling on the right posterior region of the mandible associated with clinically missing 3rd molar. The lesion was completely enucleated under general anesthesia along with the extraction of impacted molar.

Compound Odontoma

Odontoma is defined as calcifying benign odontogenic tumor composed of various tooth tissues such as enamel, dentin, pulp, and cementum and representing the second most common odontogenic tumor of the jaw bones. These lesions are often associated with impacted permanent teeth. They are usually small, asymptomatic and diagnosed after routine radiographic examination. The aim of this work was to report a case of a compound odontoma in the anterior maxilla of a 35-year-old woman, which was causing the impaction of the maxillary left central incisor. A removal of the tumor was planned. An orthodontic approach was proposed as a surgical procedure for orthodontic traction of the impacted tooth. After 12 months, the clinical and radiographic examination revealed the eruption of the impacted incisor. The recommended treatment of compound odontoma is the complete removal of the tumour. An orthodontic approach may be indicated to correct any malocclusion or to perform the traction of the tooth, due to a possible impaction.

A seven-year-old female mongrel dog was presented at the Sokoine University of Agriculture Teaching Animal Hospital for second opinion regarding a progressive swelling of the right hind limb of two months duration. Clinical examination revealed a loss of body condition, tachypnea and tachycardia, a painful immobile solid mass of 20 cm x 14 cm x 10 cm located on the right stifle joint, leucocytosis, and anaemia. Radiographic examination of the joint revealed marked soft tissue swelling with amorphous areas of mineralization and complete destruction of the proximal tibia. Smooth and solid periosteal reaction was seen around the tibia and fibula with a Codman’s triangle. Multiple nodules and a mass with soft tissue opacity were seen in the lung fields. Post-mortem examination revealed separation of tibia and fibula, softening of the proximal parts of the tibia, and complete integration of the proximal region of the two bones and articular tissues into the surrounding muscular tissues. Multifocal nodular lesions of variable sizes were mostly found in the lungs and partly in the liver. Histologically, predominantly oval and round cells with variable nuclear sizes and moderate mitoses were observed in tissue samples from the joint, lungs and the liver although some parts of the lung metastases showed both round and spindle shaped tumor cells. Clinical profile is suggestive of aggressive biphasic (spindle and epithelial) type of synovial cell sarcoma with lung and liver metastasis. Early radiographic and biopsy examination of persistent musculoskeletal nodules is recommended for early diagnosis and interventions.

Variable Clinical Presentation

Traumatic oral injuries present their own unique restorative challenges to the clinician due to their variable clinical presentation. In such cases, achieving optimum aesthetics and function in the maxillary aesthetic zone is challenging. This case report describes the rehabilitation of a patient with immediate implant placement after suffering trauma to the oral cavity resulting in a complete loss (avulsion) of a permanent central incisor tooth. In order to preserve the existing soft and hard tissue and to achieve predictable and aesthetically pleasing results, we decided to place an immediate implant as opposed to replantation of the avulsed tooth. Flapless implant surgery was planned and a dental implant (Bio horizons Implant Systems, Inc.) was placed following non-submerged protocol. At six month’s follow-up, the clinical and radiographic examination revealed a well osseo-integrated implant with an intact buccal cortical plate. Continuous...
