Cementum, pulp, periodontal ligament, and bone response after direct injury with orthodontic anchorage screws: a histomorphologic study in an animal model.

30 Oct 2009 PURPOSE: To assess the histologic response of the periodontium, cementum, and pulp after intentional root injury with titanium screws. MATERIALS AND METHODS: Three female beagle dogs were used, and a total of 60 self-drilling/self-tapping miniscrews ... Read more...

Hexagonal micron scale pillars influence epithelial cell adhesion, morphology, proliferation, migration, and cytoskeletal arrangement.

29 Sep 2009 A desirable attribute of implants penetrating epithelium is the inhibition of downward epithelial migration. Simple grooved topographies can inhibit this migration either directly or indirectly by promoting connective tissue attachment, but few ... Read more...

Behavior of rat periodontal ligament cells on fibroblast growth factor-2-immobilized titanium surfaces treated by plasma modification.

29 Sep 2009 The aim of this study was to investigate the behavior of rat periodontal ligament (PDL) cells cultured on fibroblast growth factor-2 (FGF-2)-immobilized titanium surfaces treated by oxygen (O2) plasma. We used cell disks (15 mm in diameter), and ... Read more...
