Influence of a High-fat Diet in the Progression of Apical Periodontitis.

Introduction: This study evaluated the effects of a high-fat diet (HFD) on the progression of apical periodontitis (AP) in rats.

Methods: Eight-week old Wistar rats (N = 24) were included in this study. Half of the animals received an HFD and the other half a control diet (CD).

Effect of different implant abutment surfaces on OBA-09 epithelial cell adhesion.

For the long-term success of implants, it is necessary to achieve a direct contact between the implant and the subjacent bone. To avoid bacterial penetration that could adversely affect the initial wound healing as well as the long-term behavior of the implants, an early tissue barrier must form that is able to protect the biological peri-implant structures. Given the need of an effective tissue early barrier around dental implants, the present study evaluated, in vitro, the influence of physical and chemical characteristics of two implant abutment surfaces on gingival epithelial cells (OBA-9) adhesion.
