Abstract: Introduction The importance of good communication in dentistry is proven in terms of both medical satisfaction and patient-related recovery and prevention. The present work deals with the comparison of communicative abilities and the communicative self-assessment of licensed dentists as well as students of dentistry with special emphasis on the influence of the treatment experience. Materials and Methods A total of 34 dentists (experimental group) with an average work experience of 16 years and 36 students (control group) with an average of 1.4 years of treatment experience were included. In addition to a tutor, four types of simulation patients with standardised trained roles (anxious, critical, dissatisfied and difficult to motivate) were used to create reproducible conversations. The self-assessment and evaluation of the conversation took place by completing questionnaires. Here, an introductory questionnaire was distributed to the participants prior to the conversation and another one after intervention. Whilst the tutors completed their survey during the intervention, the simulation patients answered their questions after the conversation. Results The results showed that the dentists rated their own communication skills significantly higher than the students for anxious (P 0.001) and unmotivated patients (P = 0.026). However, the evaluation of the simulated patients showed that the students achieved higher overall empathy scores (42.03 vs 38.77, P = 0.016).brbrConclusion

Abstract: The aim of this randomized, controlled clinical trial was to isolate and identify viable microorganisms in the saliva of study participants that continuously used a stannous and fluoride ion (F/Sn)-containing toothpaste and mouth rinse over a period of three years in comparison to a control group that used stannous ion free preparations (noF/Sn) over the same time period. Each group (F/Sn and noF/Sn) included 16 participants that used the respective oral hygiene products over a 36-month period. Stimulated saliva samples were collected at baseline (T0) and after 36 months (T1) from all participants for microbiological examination. The microbial composition of the samples was analyzed using culture technique, matrix-assisted laser desorption ionization-time of flight (MALDI-TOF) mass spectrometry, and 16S rDNA Polymerase Chain Reaction (PCR). There were only minor differences between both groups when comparing the absolute values of viable microbiota and bacterial composition. The treatment with F/Sn led to a slight decrease in disease-associated and a slight increase in health-associated bacteria. It was shown that the use of stannous ions had no negative effects on physiological oral microbiota even after prolonged use. In fact, a stabilizing effect of the oral hygiene products containing stannous ions on the health-associated oral microbiota could be expected
