Materiales y metodos: Se utilizaron las historias clinicas de 111 pacientes que tenian diagnosticos histologicos confirmado de tumores malignos de senos paranasales; se realizo un estudio de forma retrospectiva desde Abril del 2000 hasta Enero del 2012. La recoleccion de datos incluyo datos demograficos, las manifestaciones clinicas, los diferentes planes de tratamiento, y la histopatologia de cada tumor. Resultados: Los pacientes fueron 69 (62,16%) hombres y 42 (37,83%) mujeres (La relacion hombre-mujer fue de 1.6:1), con una edad media de 49±12.2 anos (Rango de edad de 21 a 88 anos). Se observo un alto nivel de incidencia en la quinta decada de vida (26.3%). Los tipos histologicos mas frecuentes fueron el de carcinoma de celulas escamosas (43.5%), y el carcinoma adenoide quis...

Materials and methods: We retrieved information regarding 151 cases that were diagnosed as having PyG at the Department of Oral and Maxillofacial Surgery, Mashhad Dental School, Mashhad, Iran, during a 10 year period from 1995 to 2005. Data were reviewed and information regarding following variables were collected: age, gender, lesion site, and clinical and histopathologic properties. Results: The predominance of PyG among females was obvious in this series and the female-to-male ratio was 2.21:1. The patients’ ages ranged from 2 to 79 years (mean, 29.1 years).The greatest degree of occurrence (24.8%) was observed in the second decade of life. The most frequently affected site was the gingiva (70.3%); other regions were the tongue, lips, buccal mucosa, palate, and ...

Studies that were published before October 2015 were electronically and manually searched in three databases. We included human studies that reported the amount of NB, RG and ST in the biopsies taken from the grafted sinuses. Based on the applied grafting materials, extracted data were categorized into different groups. Furthermore, extracted data were classified into three groups based on healing time: (i) ≤ 4.5 mo; (ii) 4.5–9 mo; and (iii) ≥ 9–13.5 mo. The search provided 791 titles. Full text analysis was performed for 258 articles resulting in 136 studies that met the inclusion criteria. Autogenous bone (AB) resulted in the highest amount of NB and lowest amount of RG compared to other grafting materi...

Eighteen patients who had osseous defects in the mandible were selected. In the test group (n=9), alveolar cortical bone in the area of regeneration was perforated. No decortication was performed in the control group (n=9). Subsequently, defects were augmented by guided bone regeneration using resorbable membrane and bovine bone. After a healing period of 7 months, trephine cores were harvested for histological and histomorphometric analysis of the grafted areas. Histomorphometry demonstrated that the amount of newly formed bone in the test group (27.8%) was greater than that in the control group (25.3%), but the difference was not statistically significant (P=0.13). However, the mean number of microvessels in the test group was significantly higher than that in the control group (P=0.01). This study found that cortical bone perforation favourably affects the amount of new bone formation in the grafted sites after 7 months of healing. Cortical bone perforation significantly increase number of new vessels (angiogenesis) of the regenerated bone. Further randomized clinical trials are required to confirm these results.

To produce high quality reproducible photos, it is necessary to be familiar with principles of clinical photography. This paper provides oral and maxillofacial surgeons with an overview of principles of photography, archival storage, error avoidance and clinical applications of digital cameras for obtaining a quality image.How to cite this articleDanesh-Sani SA.

Decreased vascularity of bone as well as compromised immune system may result in oral and maxillofacial complications. Osteomyelitis is life-threatening problem in these patients usually associated with dental caries or abscess. Dental practitioners could play a crucial role in early diagnosis of osteomyelitis and avoid inappropriate treatments and further complications.How to cite this articleMakarem A, Lotfi N, Danesh-Sani SA, Nazifi S.
