Pharmacological Therapy for Treatment of Recurrent Central Giant Cell Lesion in a Child.

A central giant cell lesion (CGCL) is a reactive lesion that causes destruction of bone and soft tissues and has a high recurrence rate. Only 16 percent of CGCLs are observed in children. Treatment is determined by the aggressiveness and size of the lesion and it usually involves curettage or resection. Alternative treatments, such as nasal calcitonin and intralesional corticosteroid injections, are also used. The purposes of this paper are: (1) to report the case of a nine-year-old patient who presented with a CGCL; (2) to describe its pharmacological management; and (3) to review the literature about the clinical, radiographic, and histological features of CGCL.

Failure of Osseointegrated Dental Implant After Alveolar Nerve Transposition: A Report of an Unusual Complication and Surgical Management.

PURPOSE: To describe an unusual case of mandibular fracture after osseointegrated dental implant removal placed after inferior alveolar nerve transposition. REPORT OF CASE: The patient underwent inferior nerve transposition for implant placement due to lack of interarch space. Two months after metal-ceramic crowns installation, the patient began to complain of pain in the region of the implant. In an attempt to remove the implant, there was a fracture of the implant, and only two third of it was removed, leaving only the apical portion of the implant in the mandible. The patient opted for the total removal of implant. At 15 days of follow-up, the patient returned with mandibular fracture, which was treated through an internal fixation with a titanium reconstruction plate of 2.0-mm thickness with locking screws. CONCLUSION: The inferior alveolar nerve transposition may represent the only rehabilitation option, especially in cases where there is insufficient bone remaining for installation of short implants with reduced interarch space.

Septum en seno maxilar: un estudio de 91 cirugías consecutivas de elevación de piso sinusal / Septum on maxillary sinus: a study in 91 consecutive surgeries of maxillary sinus floor elevation

La elevación de piso sinusal maxilar ha sido ampliamente discutida y presenta altas tasas de éxito. El objetivo de esta investigación fue establecer la prevalencia de septum intrasinusal presente en cirugías consecutivas de elevación de piso sinusal y establecer su relación con las perforaciones de membrana sinusal. Noventa y un cirugías fueron realizadas en pacientes que presentaban indicación para instalar implantes dentales en maxila posterior; fueron incluidos aquellos pacientes que presentaron documentos clínicos íntegros (ficha clínica, radiografías, entre otros) y que no presentasen contraindicación del procedimiento; las cirugías fueron realizadas con anestesia local o general y fueron rellenados con biomateriales o hueso autógeno. El septum fue identificado mediante la imagen panorámica preoperatoria y de forma clínica intraoperatoria, mientras que cualquier complicación fue estudiada y relacionada con la presencia de septum; el estudio estadístico se realizó a través de la prueba test de Fisher siendo reconocido el valor de p<0.05. Fueron operados 72 sujetos (53 mujeres y 19 hombres) con una edad promedio de 44,5 años; en el 74,7 por ciento no se observó ningún tipo de complicación, mientras que en el 18,7 por ciento de los casos se observó perforación de la membrana sinusal. Septum sinusal fue observado en el 17,6 por ciento de los casos operados (16 senos maxilares), presentando 12 septum en posición anterior y 4 en posición posterior. La presencia de septum tuvo relación estadísticamente significativa con la laceración de membrana sinusal (p<0,05). Finalmente, podemos señalar que la presencia de septum intrasinusal se observó en 17 por ciento de los casos y se relaciona directamente con complicaciones intraoperatorias como la perforación de membrana.

Sinus lift has been widely studied and is highly successful. The aim of this research was to establish the prevalence of intrasinusal septum in consecutive surgeries for maxillary sinus floor elevation and identify the relation with sinus membrane rupture. Ninety one surgeries were realized in patients with an indication for dental implant installation in the posterior maxilla; the patient with complete clinical and medical record (card, radiography, etc.) and without contraindications for the procedure was included in the study; the surgery was realized with local or general anesthesia and the material used for inlay graft was autogenous bone or biometarials. The septum was identified by panoramic image in the preoperatory and clinically at the time of surgery; any complication was studied and related to intrasinusal septum; the statistical study was carried out with Fisher test with p value <0.05. Surgery was performed on 72 subjects (53 female and 19 male) with a mean age of 44.5 years of age; in 74.7 percent of patients no complications were observed, while 18.7 percent presented sinusal membrane rupture. The septum was observed in 18.7 percent (16 maxillary sinus), showing 12 septum in anterior position and 4 in posterior position; the presence of septum was positively related to membrane rupture (p<0.05). Finally, we can state that the intrasinusal septum was observed in 17 percent and was related to intraoperatory complications as membrane rupture.

Fibroma Osificante de Mandíbula: Reporte de un caso Clínico

El fibroma osificante es una lesión benigna de crecimiento y tumefacción deformante de evolución lenta que afecta los maxilares, principalmente en la región posterior de la mandíbula. Se manifiesta con mayor predilección en el género femenino, entre la tercera y cuarta décadas de vida. Radiográficamente, la imagen frecuentemente observada, aparece como un área radiolúcida, unilocular, bien definida y delimitada por un halo radiopaco (esclerótico); ocasionalmente puede presentarse como una imagen radiopaca. El tratamiento es quirúrgico y consiste en la enucleación total de la lesión. Este artículo relata un caso de fibroma osificante, discutiendo sus aspectos clínicos a través de la revisión de la literatura.

Ossifying fibroma is a benign lesion, with slow growth but deforming tumefaction involving the jaws, mainly the posterior region of the mandible. It is more frequent in females among the third and fourth decades of life. Radiologically, it usually appears like a radiolucent unilocular well defined area, limited by a radiopaque (sclerotical) edge; occasionally it appears as a radiopaque image. Its treatment is surgical and consists of the total resection of the lesion. This article reports a case of ossifying fibroma, with discussion of its clinical features through a literature review.
