Odontogenic Keratocysts as First Manifestation of Nevoid Basal Cell Carcinoma Syndrome: Surgical Management and Immunohistochemical Analysis.

Nevoid Basal Cell Carcinoma Syndrome (NBCCS), also known as Gorlin syndrome, is a rare autosomal dominant disorder, with no gender predilection. Individuals with NBCCS are commonly diagnosed between 17 and 35 years old and can present multiple basal cell carcinomas scattered throughout the body, presence of recurrent and early-onset odontogenic keratocysts (OKCs) and skeletal abnormalities. This article describes a case of a 13-year-old white boy who referred complaining of facial asymmetry.

Epstein-Barr virus (EBV)--associated posttransplant lymphoproliferative disorder appearing as mandibular gingival ulcers.

Posttransplant lymphoproliferative disorders (PTLDs) comprise a spectrum of complications that affect immunocompromised patients following hematopoietic stem cell transplantation or solid organ transplantation. Its incidence varies depending on the transplanted organ, occurring in approximately 2.3% of kidney transplantations.

Modified submandibular access for open reduction and internal rigid fixation in condylar fractures.

Purpose: The purpose of the present study was to describe a surgical technique for treatment of condylar fractures through the modified submandibular access, by means of a small incision in the mandibular angle that promotes a dissection between the parotideomasseteric and the transmasseteric fascia in a quick way and with low morbidity. Fixation may be made with plates and screws according to the technique prescribed by the surgeon.

Methods: Owing to the high incidence and importance of condylar fractures, various therapeutic methods have been described and may be divided into conservative and surgical methods.

Bacterial contamination along implant-abutment interface in external and internal-hex dental implants.

The aim of this research was to evaluate bacterial contamination along the implant-abutment interface in relation to the size of the interface. 80 brand name implants were used, 40 internal-hex and 40 external-hex. The implants were handled in a sterile atmosphere inside a box, where they were inoculated with 0.

Bacterial adhesion and colonization differences between zirconia and titanium implant abutments: an in vivo human study.

Purpose: Several parameters have been described for determining the success or failure of dental implants. The surface properties of transgingival implant components have had a great impact on the long-term success of dental implants. The purpose of this study was to compare the tendency of two periodontal pathogens to adhere to and colonize zirconia abutments and titanium alloys both in hard surfaces and soft tissues.
