Extensive Gingival Hemangioma in a 10-Year-Old Boy Treated by Sclerotherapy: A Case Report

f n o Because of imprecise medical terminology, the descriptions of vascular anomalies were somewhat unclear until the 1980s. Mulliken and Glowacki introuced a simplified classification in 1982 based on linical, histochemical, and cellular criteria to distinuish among various types of vascular anomalies. Vasular lesions of the oral and maxillofacial region were ivided into 2 categories: benign vascular tumors haracterized by endothelial proliferation and vasular malformations with no endothelial proliferaion. Hemangiomas are rapidly growing benign vascular tumors that often manifest in the neonatal period or during childhood. Characterized by a slow rate of regression and incomplete involution, these tumors affect female patients more frequently than male patients (3:1) and rarely recur when treated success-

Psammomatoid juvenile ossifying fibroma: case study and a review

BackgroundThe group of fibro-osseous lesions from the maxillofacial region is very heterogeneous, but what they all have in common is the substitution of normal bone by fibroblasts with the consequent formation of collagen fibers, as well as substitution by different types of mineralized tissues which may be similar to bone or cement. Within this group of lesions, the juvenile ossifying fibroma is found, considered a rare and recurrent benign fibro-osseous neoplasia. The term juvenile ossifying fibroma has been used in the literature to describe two histopathological variations of conventional ossifying fibroma. These variations are trabecular juvenile ossifying fibroma and psammomatoid juvenile ossifying fibroma. Psammomatoid juvenile ossifying fibroma is an uncommon bone-forming neoplasm with aggressive local growth. Diagnostic of this lesion occurs after the correlation of clinical, imaging, and histopathological findings. Proposed treatments range from enucleation and curettage to resection of the tumor.ObjectivesThe present article has as its objectives to report an uncommon case of a 4-year-old male patient treated by conservative approach and revise the literature on juvenile ossifying fibroma.ConclusionsPsammomatoid juvenile ossifying fibroma, for its being very uncommon, warrants further investigation in order to establish the best treatment, principally in children, with a view to minimizing mutilating treatments. In the case examined, a conservative treatment was chosen, where the surgeon established curette and cryotherapy, and the reintegration of the child in his social environment, without relapse during the first year of therapy.

Management of Ankylosed Maxillary Canine With Single-Tooth Osteotomy in Conjunction With Orthognathic Surgery

Ankylosis of teeth is the abnormal adherence of alveolar bone to dentin or cementum. Ankylosis of a submerged maxillary canine can be challenging when striving for an optimal occlusal and esthetic treatment outcome with orthognathic surgery. If an ankylosed tooth does not respond to orthodontic forces, surgical procedures may be indicated to facilitate movement of the tooth to the correct position including a single-tooth segmental osteotomy to reposition the alveolar bone including the ankylosed tooth. The objective of this case report is to describe the treatment of a patient with an ankylosed submerged maxillary right canine, with a single-tooth osteotomy performed to reposition the tooth into its correct position concomitant with double-jaw orthognathic surgery and TMJ surgery.

Appositional bone graft tunneled: Technical note

Highlights • The tunnel technique for onlay bone grafting is a simple and easy to perform technique.• We had no implant loss with the tunnel technique in the onlay bone graft.• The fact that the periosteum is kept intact, is a crucial element for the survival and viability of the graft block.
