cemento-ossifying fibroma is a fibro-osseous lesion that has benign neoplastic behavior. we report two cases of cemento-ossifying fibroma (cof) and review the literature in order to study the imaging findings of cof. it is almost unavoidable that diagnosis of fibrous dysplasia from cof will be complicated by the fact that some pathologic features are shared by both lesions. so the final definit...

background: recently, there has been interest in non‑mammalian collagen sources such as fish collagen in the development of biomatrices and scaffolds for periodontal regeneration. in the present study, a novel collagen barrier membrane of fish origin was assessed in the treatment ofperiodontal intra‑bony defects. materials and methods: ten systemically healthy chronic periodontitis patients hav...

introduction in radiography, dose and image quality are dependent on radiographic parameters. the problem is caused from incorrect use of radiography equipment and from the radiation exposure to patients much more than required. therefore, the aim of this study was to implement a quality-control program to detect changes in exposure parameters, which may affect diagnosis or patient radiation do...

PURPOSE To evaluate the interference of radiographic factors in the appearance of sensory deficit related to inferior alveolar nerve (IAN) after third molars (3Ms) removal.
