Stafne’s bone cavity (SBC) is an asymptomatic lingual bone cavity situated near the angle of the mandible. The anterior variant of SBC, which shows a radiolucent unilateral ovoid lingual bone concavity in the canine-premolar mandibular region, is uncommon. A 73-year-old man was referred for assessment of loss of mandibular bone. Panoramic radiographs and computerized tomography scans showed a well-defined lingual bony defect in the anterior mandible. Analysis of imaginological documentation, made 14 years ago, revealed a progressive increase in mesiodistal diameter and intraosseous bony defect. The soft tissue obtained within the bony defect, microscopically revealed fibrous stroma containing blood vessels of varied caliber. The current anterior lingual mandibular bone defect case is probably caused by the salivary gland entrapped or pressure resorption, which can explain the SBC pathogenesis.KEYWORDSBone defect; Mandible; Cone beam computed tomography; Diagnosis; Case report.

The aim of this study was to report the frequency and clinical-radiological features of cases of lingual cortical mandibular bone depressions (LCMBD) diagnosed in consecutive panoramic radiographs and cone-beam computed tomography (CBCT) scans from a Brazilian population. The methods included a retrospective analysis of consecutive panoramic radiographs, charts from the Oral Medicine clinic and consecutive CBCT scans. All cases diagnosed as LCMBD were selected and clinical-radiological data were retrieved from the clinical charts and by the analysis of the image exams. Twenty LCMBD cases diagnosed in 18 patients were found, including 2 from 3,000 consecutive panoramic radiographs (0.07%), 6 from 2,421 Oral Medicine patients (0.25%) and 10 from 1,684 CBCT scans (0.59%). The 18 patients had a mean age of 51.5 years and 13 were males. Two patients presented bilateral lesions. Fourteen images (70%) were classified as well-defined. Eighteen affected the posterior area of the mandible and two affected the anterior mandible. Size of the lesions was larger in younger patients. In conclusion, there seemed to be a considerable radiological heterogeneity when comparing the LCMBD cases and it seemed that the images decreased in size with the increase of patient's age.

ABSTRACT Exostoses or hyperostoses are benign bony outgrowths originating from the cortical bone and depend on their location for a more precise designation. The most common types found in the oral cavity are the torus palatinus and the torus mandibularis. Buccal and palatal exostoses are located along the buccal aspect of the maxilla and/or the mandible (commonly in the premolar and molar areas) and on the palatal aspect of the maxilla (usually in the tuberosity area), respectively. The etiology of exostoses still hasn’t been enlightened but an interaction between environmental and genetic factors is accredited. They are usually asymptomatic, unless the mucosa becomes ulcerated. The frequency of exostoses increases with age, having their biggest prevalence from 60 years old, being more common in men and suffering ethnic influences. A thorough evaluation is important for the correct diagnosis since other lesions have similar clinical characteristics to the exostoses such as osteomas. The majority of exostoses are diagnosed clinically along with radiographic interpretations, making the biopsy dispensable and the treatment is usually unnecessary. The aim of this article was to describe a case report of bilateral maxillary exostosis, unusual, in a female patient. If an excessive amount of bone is present the exostoses may exhibit a relative radiopacity on dental radiographs. Initially, periapical and panoramic radiographs were performed to evaluate the alterations. Due to the size of the exostoses a concomitant Cone Beam Computed Tomography was performed to confirm the diagnosis. The patient is in follow-up.

Stafne Bone Defect

SummaryBackround/Aim: Stafne bone cavity which is also known as lingual mandibular bone defect is generally seen in the posterior region of the mandible. Stafne bone defects of the anterior mandible are very rare, with around 50 cases reported in the English literature. They are generally asymptomatic and incidental lesion findings may be diagnosed during a radiographic examination.Case Report: A 59 year-old female patient was examined for dental complaints. Panoramic radiography revealed a unilocular lesion at the left incisor- premolar area. Dental volumetric tomography scans showed a concavity at the lingual side of the related area. Magnetic resonance imaging was suggested for possible soft tissue pathology and, depending on MRI finding, the cavity was initially diagnosed as Stafne bone defect.Conclusion: The aim of this case report is to describe an unusually located Stafne bone cavity with special emphasis to the need of using special imaging modalities.

Ameloblastoma is the term first suggested by Churchill in 1934. This is an odontogenic tumour where epithelium is the neoplastic component with no involvement of ectomesenchyme. As a well known fact that ameloblastoma is a benign tumour which invades locally with most common site being the third molar region mandibular jaw. Most commonly ameloblastoma occurs in mandibular third molar region upto 66%, followed by 11% in mandibular premolar region, 10% in mandibular anterior region, 6% in maxillary anterior and posterior region and only 1% in maxillary premolar region. Here in this case report we present a rare case of unicystic ameloblastoma occuring in anterior mandibular region crossing the midline along with radiographic investigations done in two dimensional and three dimensional imaging.

AbstractImplantology has become an integral part of dentistry. Initially implant dentistry was surgically driven with implant placement thatwas determined by the available bone. Following this although osseo integration was achieved, the outcome many a times didn't fulfil the basic function anaesthetics. The correction after implant placement with help of angulated abutments in anterior region will produce undesirable aesthetics. Prosthetically driven implant placement will help in the overall function and aesthetic. This case report describes managing a horizontal defect in the anterior mandibular region with help of allogenic graft material and establishing the prosthetically driven approach.

Large mandibular bone defects can be difficult to treat in dogs, with a high risk of mal or nonunion due to instability and risk of infection. This case report describes the use of autologous clotted blood mixed with biphasic calcium phosphate microparticles to fill a defect in a nonunion fracture and promote bone regeneration in a dog using a 2-stage surgical approach. This new method was designed and tried in a dog with a chronic, unstable mandibular fracture associated with a large sequestrum. Initial treatment involved debridement of the lesion, then the oral wound and oral vestibule were reconstructed in 2 layers. Four weeks later a second stage surgery allowed placement of a pre-contoured maxillofacial plate to bridge the defect, which was filled with a blood/biphasic calcium phosphate compound implant. Cone-beam computed tomography was used prior to the initial surgery for preoperative planning and 3-D printing of a mandibular template for plate contouring. CT was subsequently used to document the healing process, using a bone density measurement tool to assess bone regeneration. Radiographic evidence suggestive of osseointegration was observed within 6 months with effective filling of the defect and restoration of alveolar ridge continuity. A return to normal and atraumatic occlusion was considered excellent. Cone-beam computed tomography was found useful to document radiographic evidence of osseointegration, bone regrowth and remodeling. This case report is to serve as a proof-of-concept study and should be followed by a prospective evaluation.
