Dental training in evidence-based dentistry: A replication study
Published On: October 16, 2017 | Pages: 066 - 071
In the area of education research, it is well-known that studies of a defined question are seldom replicated. Furthermore, e-learning resources with evidence-based content in dentistry have received relatively little attention from researchers. ...

Comparative evaluation of microleakage among Resin-Based and nonResin-Based Restorative Materials in dentine cavities
Published On: February 06, 2019 | Pages: 001 - 005
The aim of this randomized in vitro study is to clarify whether resin based restorative materials (RBRM) behave in a way comparable to non-resin based restorative materials (non-RBRM) in dentine-limited cavities with regard to their marginal fit. For this purpose, cylindrical standardized cavities (diameter: 3.0 +/- 0.1 mm, depth: 1.5 mm) were placed on buccal surfaces of sixty human molars and restored with three non-RBRM (glass ionomer cement, amalgam, phosphate cement) and three adhesive (composite, compomer, ormocer) restoratives. Aging of the samples was achieved by thermal cycling (500 cycles). The marginal gaps could be made visible with a dye penetration test (methylene blue 2%). Using a diamond internal hole saw, 5 cuts were made through the cavity and measured under an incident light microscope at 10x magnification. ...

Influence of structured reporting of tooth-colored indirect restorations on clinical decision-making
Published On: March 12, 2019 | Pages: 006 - 010
The aim of the present study was to discover what influence structured reporting (study group = A) of toothcoloured lab-fabricated restorations has on clinical decision-making following international guidelines. By way of comparison, the conventional approach in the form of short reporting with 5 items (control group = B) was used as gold standard. The study was carried out in the first clinical semester of dentistry (n = 68) at the Goethe University in Frankfurt am Main. In the study group, indirect ceramic restorations were assessed on a scale of 1 (very good) to 5 (insufficient) using structured reporting (7 items, each with 5 subgroups) in accordance to World Dental Federation (FDI) - standards. Following this, the clinical decision on the insertion of the restoration was made. To evaluate the quality of the structured reporting, sensitivity, specificity, confidence intervals (Cl) and the respective predictive values (positive = PPV, negative= NPV) were determined. Based on FDI reporting, a ceramic inlay is also favored with a great degree of certainty in clinical decisions: this was the true in 34 procedures out of a total of 38 clinically incorporated ceramic inlays [sensitivity 67% (95% CI: 46 ...

Hand-operated and rotary mity instruments in combination with an endodontic handpiece and endodontic motor preparation: A comparison of shaping ability in simulated curved root canals
Published On: June 19, 2019 | Pages: 013 - 020
The aim of this in vitro pilot study was to describe the shaping ability of a rotary nickel-titanium (NiTi) instrument in combination with different torque-controlled endodontic devices and to compare them with NiTi files in combination with a conventional preparation by hand in severely curved root canals of plastic blocks. Thirty blocks simulating a severely curved root canal were divided into three groups (n=10 for each). All canals were prepared with NiTi files to an ISO size of 40 using an apical-coronal preparation technique. Mity Roto 360° files (Loser, Leverkusen, Germany) were used for the automatic systems, while Mity K-Files (Loser, Leverkusen, Germany) were used for the preparation by hand. We evaluated the frequency of instrument failure, the preparation time, loss of working length, loss of weight, elbow-zip effects, and changes in root canal anatomy. ...

Effect of the additive dentine conditioning in all-in-one adhesives on the bonding strength at simulated intrapulpal pressure
Published On: July 05, 2019 | Pages: 021 - 027
The aim of the study was to investigate the infl uence of additive etching of dentine with phosphoric
acid on the shear bond strength of two different, self-conditioning, all-in-one adhesives [Adect (ADE), and
One-Up-Bond F (OUP)]. Dentine discs from 90 human molars (n = 15 per group) were exposed to penetration by Ringer's solution (60 cm height, 22 °C) by means of a perfusion device. ...

Peer-based dental composite training course
Published On: July 22, 2019 | Pages: 032 - 036
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.

Oral-health implications and maintenance needs of Removable Partial Dentures (RPDs) worn during pre-prosthetic treatment
Published On: October 22, 2019 | Pages: 056 - 064
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. ...
