statement of problem: among periodontal defects, the furcation involvement represents one of the most chalenging scenarios due to the difficulty of achieving a predictable improvement regardless of the type of periodontal therapy. moreover, the presence of furcation involvement has been demonstrated to considerably affect tooth prognosis. thus, treatment of furcation defects is a challenge in c...

Background: This study addressed the development of biodegradable and biocompatible scaffolds with enhanced biomechanical characteristics. The biocompatibility and the cationic nature of chitosan (CTS) make it more effective as a bone grafting material. Methods: The hydroxyapatite nanoparticles (nHA) were synthesized by hydrothermal method, and bioglass (nBG) (50% SiO2-45% CaO-5% P2O5) was synt...

An odontome is a slow growing and non-aggressive odonotogenic tumor composed of enamel,dentin,cementum and pulp tissue.complax odontome comprise of an unorganized mass of odonotogenic tissues,morphologically not resembling the normal teeth.in this report,a case of rare odontoma in a ten-years-old boy that caused dalayed eruption of a maxillary right farst permanent molar,buccal expansion of the...

Bone is the most implanted tissue after blood. The major solid components of human bone are collagen (a natural polymer, also found in skin and tendons) and a substituted hydroxyapatite (a natural ceramic, also found in teeth). Although these two components when used separately provide a relatively successful mean of augmenting bone growth, the composite of the two natural materials exceeds thi...

Although hard tissue injuries are uncommon in the pediatric patient, dentists may be involved in the initial assessment of these patients. In this paper, we review fractures of the facial skeleton with a focus on dentoalveolar injuries. Minimally displaced fractures in pediatric patients can be managed conservatively, while displaced fractures may require open approaches and rigid fixation. New...
