“…Moreover, among the unusual clinical features observed in some SBC lesions, noteworthy is the expansion of cortical bone with resorption, the mandibular canal displacement, and recurrence. These findings are atypical and although the SBC is an innocuous lesion with no significance, some cases may have an unusual biological behavior with more aggressive aspects in its clinical course (19,20). …”

BackgroundJaw pseudocysts are benign osseous lesions of unclear etiology. Among these, the simple bone cyst (SBC) and aneurysmal bone cyst (ABC) are intriguing bone pathologies still rarely studied together. This retrospective study aimed to present the long-term case series of patients with jaw pseudocysts focusing on the clinical, radiographic, and transoperative aspects.Material and MethodsA retrospective case series of patients with SBC and ABC was performed. Clinical, radiographic, and transoperative aspects of both pseudocysts were reviewed from the histopathological archives of 20,469 cases between 1959-2012. All descriptive data were summarized.ResultsOf 354 (15.25%) bone pathologies, 54 cases of jaw pseudocysts were found, with 42 (11.86%) SBC and 12 (3.39%) ABC cases. For both lesions, most of the sample were young Caucasian women with an asymptomatic posterior mandible lesion with undetermined time of evolution and none trauma history. A unique radiolucent scalloped lesion presenting an empty cavity were also observed for both conditions. However, some atypical findings were found for SBC including: the expansion of bone cortical, tooth resorption, displacement of the mandibular canal, and recurrence. The absence of painful symptoms and the lack of classical blood-filled cavity were observed in some cases of ABC.ConclusionsThe SBC and ABC are bone pathologies with few retrospective studies, no previous studies on the two conditions, varied nomenclature, and atypical aspects in some cases. Therefore, the knowledge of clinical, imaging, and transoperative features of such pseudocysts are clinically valuable as diagnosis hypothesis of radiolucent lesions of the jaws. Key words:Simple bone cyst, aneurysmal bone cyst, pseudocysts, jaws.

“…SBC of the mandible usually occurs secondary to trauma, typically after tooth extraction with subsequent intramedullary haemorrhage. Most SBCs occur before the age of 20 with female predominance [18]. In up to 75 % of all cases, SBCs are seen in the marrow of the posterior mandible.…”

ObjectivesRadiolucent mandibular lesions seen on panoramic radiographs develop from both odontogenic and non-odontogenic structures. They represent a broad spectrum of lesions with a varying degree of malignant potential. The purpose of this review is to illustrate the characteristic imaging findings—as well as the clinical and histological features—of common and uncommon radiolucent lesions of the mandible.MethodsThis review article is based on the retrospective evaluation of 11,725 panoramic radiographs seen in our institution during the past 6 years. It provides a comprehensive, practical approach to the radiological interpretation of radiolucent lesions of the mandible. To facilitate the diagnostic approach, we have classified radiolucent lesions into two groups: lesions with well-defined borders and those with ill-defined borders.ResultsLesion prevalence, age of manifestation, location within the mandible, relationship to dental structures, effect on adjacent structures and characteristic findings at computed tomography (CT), cone beam CT (CBCT) and magnetic resonance imaging (MRI) with diffusion-weighted imaging (DWI) are discussed. Pitfalls including malignant lesions mimicking benign disease and pseudo-lesions are equally addressed.ConclusionKnowledge of the characteristic imaging features of radiolucent mandibular lesions narrows the differential diagnosis and is crucial for the identification of those lesions, where biopsy is indicated for definitive histology.Teaching points• Panoramic X-rays, CT and MRI are essential for the work-up of radiolucent mandibular lesions.• Lesion borders, location within the mandible, relationship to dental structures and tissue characteristics on cross-sectional imaging are indispensable to narrow the differential diagnosis.• High-resolution CT and CBCT play a major role for the assessment of lesion margins and their relationship to important anatomic structures, such as the inferior alveolar nerve.• Although most radiolucent lesions with well-defined sclerotic borders are benign, MRI may reveal clinically unsuspected malignant disease.

BACKGROUND Orthopantomography plays a vital role to diagnose mandibular lesions. Odontogenic benign tumours may occur at any period of odontogenesis. Those who develop during first stage of teeth formation do not contain calcified tissue and are therefore referred to as soft. When they develop during second stage (formation of enamel and cementum) they may contain calcified tissue so known as hard lesion. Orthopantomography help in such a way that tissue biopsy is necessary only to confirm the diagnosis and in some case its need may be altogether eliminated. MATERIALS AND METHODS Patients included in the study were from all age groups and under following clinical findings like pain, difficulty to open mouth, swelling, local tenderness, discharge from mouth etc. The machine use for the study is D B Troniks and the duration of the study is one year from jan-2016 to dec-2016. RESULTS A study carried out of 50 patient, after orthopantomogram found that incidence of male are more affected compare to females and most of them lying in third decade. The density of lesions were lytic followed by mixed and then sclerotic, while the margins of most of the lesions was smooth and well define. Most common lesion was dentigerous cyst followed by radicular cyst. CONCLUSION Many lesions involving the jaw produce characteristic radiographic appearances while many lesions produce protean characteristic with resultant overlap in radiographic features. With the combine help of history, clinical examination and orthopentomographical examination one can have accurate diagnosis of the lesions.
