Formative key feature examinations as innovative teaching approach in dental education: A project report.

Introduction: Clinical reasoning ability is one of the core competencies of physicians. It should already be trained during undergraduate medical education. At University Medical Center Göttingen (UMG), medical students can participate in formative key feature examinations in which they work on virtual patient cases in order to apply and deepen the procedural knowledge acquired in lectures and seminars.

Long-term results of implants and implant-supported prostheses under systematic supportive implant therapy: A retrospective 25-year study.

Background: Long-term data (>10 years) concerning the survival and success rates of implants and implant-supported prostheses are scarce.

Purpose: The present investigation represents one of the first studies on dental implants covering an observational period of 25 years.

Materials And Methods: This study presents the results obtained in 26 patients with 75 implants who participated over a 23- to 28-year period in a supportive implant therapy (SIT) program at a private dental practice.

Effectiveness of an innovative and interactive smoking cessation training module for dental students: A prospective study.

Background: Smoking is one of the world's major health problems and dental professionals are in a unique position to promote smoking cessation. However, according to the current literature, neither dental students nor dentists feel adequately prepared to counsel smokers. The purpose of this study was to develop and implement a teaching intervention on smoking cessation for fourth-year dental students and assess its effectiveness in terms of learning outcome on knowledge, communication skills and attitudes.

Decontamination efficacy of antiseptic agents on in vivo grown biofilms on rough titanium surfaces.

Objective: Four common antimicrobial agents were evaluated for their efficacy in reduction of aerobic bacteria intraorally grown in biofilms on rough titanium samples. The solutions investigated contained chlorhexidine, essential oil, octenidine, or citric acid.

Method And Materials: Twenty volunteers wore splints with titanium sleeves intraorally for 10 days.

Imaging of the midpalatal suture in a porcine model: flat-panel volume computed tomography compared with multislice computed tomography.

Objective: An investigation was conducted to compare the image quality of prototype flat-panel volume computed tomography (fpVCT) and multislice computed tomography (MSCT) of suture structures.

Study Design: Bone samples were taken from the midpalatal suture of 5 young (16 weeks) and 5 old (200 weeks) Sus scrofa domestica and fixed in formalin solution. An fpVCT prototype and an MSCT were used to obtain images of the specimens.

Dental therapy before and after radiotherapy--an evaluation on patients with head and neck malignancies.

The present investigation evaluates the dental care situation of patients with head and neck cancer before and after radiotherapy. The situations of these patients in 1993 and 2005 were compared to detect similarities, differences and developments. In the years 1993 and 2005, 37 and 36 patients, respectively, with head and neck cancer treated by the local departments of otorhinolaryngology and of radiotherapy were examined consecutively according to their aftercare appointments.

Decontamination efficacy of erbium:yttrium-aluminium-garnet and diode laser light on oral Candida albicans isolates of a 5-day in vitro biofilm model.

The different forms of superficial and systemic candidiasis are often associated with biofilm formation on surfaces of host tissues or medical devices. The biofilm formation of Candida spp., in general, necessitates significantly increased amounts of antifungal agents for therapy.

Preoperative sterilization and disinfection of drill guide templates.

The aim of the in vitro study was to evaluate the decontamination potential of common antiseptic solutions for heat-sensitive implantological drill guide templates. One hundred implantologists were evaluated on the basis of a questionnaire for their measures of disinfection. On the basis of these results, 80% alcohol, Octenidine 0.

Decontamination of rough titanium surfaces with diode lasers: microbiological findings on in vivo grown biofilms.

Objectives: The bactericidal efficacy of diode lasers has already been demonstrated in vitro. We investigated the reduction of aerobe bacteria - colonizing rough titanium samples in biofilms intraorally grown - by diode lasers of different wave lengths.

Material And Methods: Twenty-two volunteers participated in the trial.

Traumatic injuries to the primary dentition and effects on the permanent successors - a clinical follow-up study.

This study investigated problems in the permanent dentition that, according to history and records, were attributable to dental alveolar injuries of the primary dentition. 106 children have been involved in the study, who had experienced primary anterior tooth trauma affecting a total of 200 teeth. Thirty-nine patients (81 teeth) were available for follow-up examinations.
