EMD in periodontal regenerative surgery modulates cytokine profiles: A randomised controlled clinical trial.

The enamel matrix derivative (EMD) contains hundreds of peptides in different levels of proteolytic processing that may provide a range of biological effects of importance in wound healing. The aim of the present study was to compare the effect of EMD and its fractions on the cytokine profiles from human gingival fibroblasts in vitro and in gingival crevicular fluid (GCF) in a randomized controlled split-mouth clinical study (n = 12). Levels of cytokines in cell culture medium and in GCF were measured by Luminex over a 2-week period.

A new digital tool for radiographic bone level measurements in longitudinal studies.

Background: The reproducibility of measurements on radiographs is influenced by the techniques by which the images as well as the measurements are obtained. Thus, bias resulting from errors in the image and/or image examinations at two points in time may result in wrongful registrations of true biological or pathological changes. The aim of the present study was to propose and evaluate an indirect radiological examination technique, by which bias, when measuring radiographic bone level, could be substantially reduced as compared to the technique using direct mm measurements.

Primary prevention of peri-implantitis: managing peri-implant mucositis.

Aims: Over the past decades, the placement of dental implants has become a routine procedure in the oral rehabilitation of fully and partially edentulous patients. However, the number of patients/implants affected by peri-implant diseases is increasing. As there are--in contrast to periodontitis--at present no established and predictable concepts for the treatment of peri-implantitis, primary prevention is of key importance.

Material And Methods: Three hundred and three women were randomly allocated to receive periodontal treatment either during pregnancy (n = 147, test group) or after delivery (n = 156, control group). During pregnancy, the control group received only one session of supragingival scaling and oral hygiene instruction.

Microcomputed tomographic and histologic analysis of animal experimental degree II furcation defects treated with porous titanium granules or deproteinized bovine bone.

Background: Titanium is an interesting material for osseous reconstruction given its thrombogenic properties.
