Aims: The objective of this study was to evaluate the tongue position during deglutition with respect to the occlusal plane in class III patients with teeth in centric occlusion.

This multivariate, prospective, monocentric, observational pilot study evaluates the experimental acceptance and feasibility of a peer-based course concept. Those both theoretical and practical workshops were offered to dentistry students in all clinical semesters on a voluntary basis. In 9 courses a total of 45 students took part in small learning groups (n = up to 12 students). For the evaluation a questionnaire was used, which was divided into 4 domains, the competence acquisition consisting of 4 items (A), the acceptance of the course concept with 7 items (B), the framework conditions with 3 items (C) and the recommendation with 2 items (D). The rating was based on a scale of grades (1 = "very good" to 5 = "poor"). In the assessment of the acceptance of the course concept, the following results were obtained in 4 domains: In “A” the subjective optimization of manual skills increased by 0.49 ± 0.86 and the theoretical skills improved by 1.32 ± 0.60 grades. “B” being dived into the subcategories as presentation 1.26 ± 0.34; speaker 1.17 ± 0.21; visual models 1.26 ± 0.28; case examples 1.22 ± 0.24; theoretical advices 1.20 ± 0.22; practical implementation tips 1.18 ± 0.22; practical demonstration 1.22 ± 0.28.

The demand for aesthetic, durable and quality restorations has increased signifi cantly. Teeth should be unobtrusive and ideally minimally invasive reconstructed. It is a problem to get a permanent bond between the hydrophilic dentin and the hydrophobic composite [1,2]. Dentin adhesives play a key role in this [3-6]. In order to have feedback on the bond between composite materials and hard tooth substance, in vitro scientifi c studies are carried out. The experimental setups differ in many parameters in the studies and are therefore often not comparable.

Patients undergoing a variety of pre-prosthetic treatment regimens are commonly provided with a removable partial denture (RPD) to preserve or restore function and esthetics during this interim period. The service duration of such an interim RPD is usually limited by its inexpensive fabrication, and prolonged coverage of the abutment teeth by the denture base and clasp structures can give rise to periodontal and carious lesions. We therefore conducted a study to analyze the oral-health implications and maintenance requirements based on clinical documentation available for 575 interim RPDs covering a mean observation period of 31.21±22.02 (3-158) months.

This randomised experimental pilot study is intended to contribute to the investigations about the learning success of students in their fi rst clinical semester of dentistry using game-based learning in "Jeopardy"-setting. In dentistry, there are no studies available on this learning and teaching context.

The aim of this in vitro study was to describe the shaping ability of rotary nickel-titanium (NiTi) instruments (Mtwo, VDW, Munich, Germany) with benefi cial properties in combination with two different endodontic devices (Mtwo direct and Endo IT professional) and to compare them with Mity NiTi K-Files (Loser, Leverkusen, Germany) in combination with preparation by hand in severely curved simulated root canals of acrylic blocks

This multivariate, prospective, monocentric, single blind, observational study evaluates the experimental application of an interactive e-learning module under different tutorial guidance on the topic of EbD (Evidence based Dentistry).
