Gardner syndrome
No full textA 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
A Review of the role of Nuclear Medicine Imaging in Diagnostic Dentistry
No full textThe increasing scope of nuclear medicine imaging as a diagnostic utility is impressive. Plain film radiographs, computed tomography (CT) scans and magnetic resonance imaging (MRI) diagnostically provide high-quality images but provide little physiological information about disease processes. Nuclear medicine imaging modalities advantageously can characterise the early dynamic physiological changes in a diseased environment. Dental professionals working within the arena of integrated holistic health practices are likely to encounter patients having had procedures like conventional scintigraphy, single photon emission computed tomography (SPECT), hybrid SPECT/CT and positron emission tomography computed tomography (PET/CT). The aim of this review is to acquaint the oral health care professional with some commonly utilised nuclear medicine techniques, the principles upon which such modalities are based and their applications in the diagnosis of head and neck pathology to facilitate enhanced multidisciplinary patient management
Cone beam computed tomography use in sialolithiasis of the submandibular salivary gland
No full textA 62-year-old diabetic male patient presented with right sided facial pain associated with a firm palpable mobile mass in the right submandibular area. Following initial examination, cone beam computed tomography (CBCT) investigation demonstrated multiple smooth homogenous calcifications (Figure 1) collectively measuring 12mm x 9mm x 8mm within the region of the right submandibular gland (Figure 2). On resection of the submandibular gland, the histological features of the lesion were confirmed to be those of chronic sclerosing sialadenitis supporting the clinical impression of a sialolith
Maxillofacial Radiology 195
No full textA 48 year old asymptomatic male patient presented with a mass on the left maxilla with a reported awareness of two years. Clinical examination revealed normal mucosa overlying buccal and palatal swellings in dental region extending from the 23 to 27. Tooth 26 was missing and teeth 24, 27 and 28 demonstrated displacement
A micro-computed tomographic evaluation of dentine thicknesses of first molar roots: A review of the literature with illustrative cases
No full textThin dentinal walls of first molars can significantly impact the success and outcomes of endodontic procedures, including root canal treatment. Root canal treatment is commonly performed on first molars, which are prone to decay due to their early eruption and complex occlusal structure. The treatment entails a series of mechanical and chemical disinfection techniques where the root canal spaces are enlarged and can be compromised by perforations leading to infection, inflammation, and eventual tooth loss. The thinner the dentine, the greater the likelihood of perforation. ‘Danger zones’ have been identified as the distal aspect of mesial/mesiobuccal roots and the mesial aspect of distal roots. Knowledge of dentine thickness patterns in dental roots and understanding factors that influence dentine thickness can help reduce the risk of perforation and improve treatment outcomes. This literature review gives an overview of various aspects of the dentine thickness of the maxillary and mandibular first permanent molar. The content is supported by illustrative micro-CT images and clinical cases. Treating physicians should take note that variations in dentine thicknesses have been reported between sexes, with aging and among populations, but unfortunately no studies on dentine thickness could be found specifically for the South African context
