Peripheral Ossifying fibroma: a clinical report.

Most localized growths on the gingiva are considered to be reactive rather than neoplastic in nature. The authors describe a 20-year-old male patient with a peripheral ossifying fibroma in the maxilla exhibiting significant size with the disease duration of one year. The signs of recurrence in spite of thorough excision a debridement exposed the need for further study of the causes of recurrence.

Effect of variation of root post in different layers of tooth: linear vs nonlinear finite element stress analysis.

The objective of this study was to obtain an accurate stress distribution pattern on different domains of a post- and core-treated tooth, taking into account the nonlinear properties of the periodontal ligament (PDL). Linear stress and deformation analysis was carried out using four posts, different in constitution and shape. Accurate three-dimensional models of a restored tooth with different layers were prepared using CAD modeling software.
