Giant Mandibular Bone Defect: Report of a Case

Stafne bone defect in the anterior mandible

“…Sometimes, the jaws might be affected bilaterally (11%). 20 Radiographic attributes of the Stafne bone cavity are not always the same. Usually, they appear as circumscribed, unilocular radiolucencies; however, multilocular appearance can be seen.…”

“…To avoid an unnecessary endodontic treatment, a pulp vitality test should be performed. 13,19,20,26 A residual cyst that develops after the incomplete removal of an inflammatory cyst may mimic SBDs if the lesion is in an edentulous area. Residual cysts tend to expand, displace teeth and cause resorption in the bone unlike SBDs.…”

Stafne Bone Cavity in the Anterior Mandible

“…11,28 Of all cases in the literature, 7 cases involve the mandible in bilateral form. 4,12,16,28,29,47,60 When bilateral cases were investigated solely, there were 5 men with a peak incidence in the fifth and sixth decades. Recently, Smith et al 28 Most of the cases were discovered during routine oral radiographic examination because they were often asymptomatic like the posterior Stafne bone cavities.…”

“…The most extended lesion was described to comprise molar to molar. 29 Radiographically, the bone cavities usually appeared as circumscribed, unilocular radiolucencies, 27Y34,47Y50 except for a case that exhibited a multilocular appearance. 11 Sometimes the borders were sclerotic, and in other instances, they were not clearly defined.…”

“…16,28Y32,60 In most cases, the radiolucency was located either entirely beneath the root apices 1,6,9,10,17,20,27,32,34,37,42,47Y50,62 or partially superimposed over the apices. 4,5,8,19,28,29,31,38,39 In few cases, it appeared between the roots of the adjacent teeth 8,16,21,27,39,60 or in edentulous areas. 3,7,14,15,21,27 Occasionally, the displacement of the roots of the teeth can also be seen in the radiograph.…”
