The literature on radiolucent lesions in unerupted permanent teeth is reviewed with particular attention to etiology. A case is presented which demonstrates severe coronal destruction of a mandibular second permanent molar. Histological evidence also is presented to confirm diagnosis of external resorption. Based on previous literature and the results of this case, the authors conclude that the...
The following is a report of a 16-year-old boy with history of pain in the maxillary left central incisor and in the maxillary sinus area. Radiographs showed a w e l l d e m a r c a t e d , u n i l o c u l a r m i x e d radiolucent-radiodense lesion.
Case description: In case 1, a 17-year-old woman presented hard and painless swelling in the left posterior mandible. Radiographically, a radiolucent area with a radiopaque was observed. A clinical diagnosis of ameloblastoma or odontogenic keratocystic tumor was established. The histopathological examination revealed an orthokeratinized odontogenic cyst. In case 2, a 23-year-old woman presented...
Adenomatoid odontogenic tumor (AOT) is a rare noninvasive odontogenic tumor that occurs mostly in the second decade of life. Based on its tooth association, AOT can be classified into three categories of follicular, extrafollicular, and peripheral types; the follicular classification is considered as the most common type of AOT. This study reported a large extrafollicular case of AOT in a 40-ye...
Background: We sought to characterize humeral-sided radiographic changes at a minimum of 2 years after reverseshoulder arthroplasty (RSA) to determine their association with specific implantation techniques.Methods: The immediate and most recent postoperative anteroposterior radiographs of 120 shoulders with primary RSAand a minimum of 2-years of radiographic follow-up were an...
In the early 1960s, Cronin and Gerow began to use a silicone bag filled with silicone gel for breast augmentation. Since then, researchers have been looking for different filler materials. An ideal prosthesis does not induce any tissue reaction, is stable, gives the breast a natural appearance, and is radiolucent during mammography. In case of rupture of the envelope, the filler material should...
