An immature tooth with pulpal necrosis and periapical pathology imposes a great difficulty to the endodontists. Endodontic treatment options for such teeth consist of conventional apexification procedure with and without apical barriers and revascularization. Calcium phosphate is a calcium silicate-based cement that exhibits physical and chemical properties similar to those described for certai...

The aim was to study bone formation in tooth extraction sockets of rats with experimentally induced renal hypertension. As soon as hypertension was detected the upper right incisor was extracted. The animals were killed at 3, 6, 9, 12, 18 and 21 days post-extraction. At day 9 the hypertensive animals showed bone formation with little osteoblastic activity, the bone was more cellular and had imm...

Dens invaginatus is a relatively common dental malformation resulting from an infolding of enamel organ into the dental papilla varying in depth into the tooth tissues. Complex morphological anatomy associated with the pulpal pathology presents inaccessibility to completely remove the necrotic pulp tissues and hence poses challenges in rendering endodontic treatment. A combination of nonsurgica...

Introduction: Complicated crown fractures involve enamel, dentin, and pulp and occur in 0.9 to l3% of all dental injuries. If left untreated, will always result in pulp necrosis but, if it handled correctly, prognosis of the pulp following a traumatic crown fracture can be favorable.
