Sex Differences in Sociability for with Altered Gut Microbiomes.

In the gut microbiome has been shown to influence multiple behaviors, including aggressive social behavior. Here, we investigate the effect of the microbiome on pro-social behavior. We predicted that reducing the microbiome would lead to a decrease in pro-social behavior in adult flies.

Occlusal wear following orthodontic treatment assessed by 3D CT scanning.

Aim: To evaluate occlusal wear after comprehensive orthodontic treatment.

Methods: Consecutive pre- and posttreatment dental casts of 30 patients who had received orthodontic treatment with stainless steel fixed appliances in both dental arches at the postgraduate clinic of Aristotle University of Thessaloniki were digitized by means of a three-dimensional CT scanner. The final sample consisted of 1,256 individual teeth (628 reference-free 3D superimpositions).

Three-dimensional assessment of dental casts' occlusal surfaces using two impression materials.

The aim of this study was to assess by means of a three-dimensional computed tomography scanning system the occlusal surface characteristics of dental casts made using two different impression materials. Alginate and polyvinyl siloxane impressions were taken of 20 dental students resulting in 40 dental casts. The casts were paired for each student separately so that each pair consisted of an alginate poured cast and a polyvinyl siloxane poured out cast.
