Acceptance of technology-enhanced learning for a theoretical radiological science course: a randomized controlled trial
<p>Abstract</p> <p>Background</p> <p>Technology-enhanced learning (TEL) gives a view to improved education. However, there is a need to clarify how TEL can be used effectively. The study compared students' attitudes and opinions towards a traditional face-to-face course on theoretical radiological science and a TEL course where students could combine face-to-face lectures and e-learning modules at their best convenience.</p> <p>Methods</p> <p>42 third-year dental students were randomly assigned to the traditional face-to-face group and the TEL group. Both groups completed questionnaires before the beginning and after completion of the course on attitudes and opinions towards a traditional face-to-face lectures and technology-enhanced learning. After completion of the course both groups also filled in the validated German-language TRIL (Trierer Inventar zur Lehrevaluation) questionnaire for the evaluation of courses given at universities.</p> <p>Results</p> <p>Both groups had a positive attitude towards e-learning that did not change over time. The TEL group attended significantly less face-to-face lectures than the traditional group. However, both groups stated that face-to-face lectures were the basis for education in a theoretical radiological science course.</p> <p>The members of the TEL group rated e-mail reminders significantly more important when they filled in the questionnaire on attitudes and opinions towards a traditional face-to-face lectures and technology-enhanced learning for the second time after completion of the course.</p> <p>The members of the technology-enhanced learning group were significantly less confident in passing the exam compared to the members of the traditional group. However, examination results did not differ significantly for traditional and the TEL group.</p> <p>Conclusions</p> <p>It seems that technology-enhanced learning in a theoretical radiological science course has the potential to reduce the need for face-to-face lectures. At the same time examination results are not impaired. However, technology-enhanced learning cannot completely replace traditional face-to-face lectures, because students indicate that they consider traditional teaching as the basis of their education.</p

Masticatory Rehabilitation of a Patient With Cleft Lip and Palate Malformation Using a Maxillary Full-Arch Reconstruction With a Prefabricated Fibula Flap
For full-arch reconstruction of an atrophied cleft maxilla with missing
premaxilla, a prefabricated microvascular free bony flap is a relevant
option. A fibula flap was prefabricated in a cleft patient who received
six dental implants and an epithelial layer. Six weeks later, maxillary
reconstruction was performed. The inpatient period could be confined to
2 weeks. A fixed provisional prosthesis was delivered after an
additional 2 weeks. A prefabricated flap allows for the reduction of the
interval without a dental prosthesis to only a few weeks, even when a
complex full-arch reconstruction of the maxilla is required
3-D based minimally invasive one-stage lateral sinus elevation - A prospective randomized clinical pilot study with blinded assessment of postoperative visible facial soft tissue volume changes
Objective: The purpose of this prospective and randomized clinical study was to assess differences in patient morbidity between minimally invasive lateral sinus elevation (study group, n = 14) and conventional one-stage lateral sinus elevation (control group, n = 12). It was hypothesized that trauma to soft tissue was reduced in the study group. Materials and methods: Optical 3-D imaging was assessed blinded on days 1 and 7 after surgery to determine the visible soft tissue swelling of the upper lip and cheeks. Postoperative pain and discomfort were evaluated by a visual analogue scale (VAS; scale 0-10). Results: Immediately and on day 1 after surgery, the study group patients rated pain and discomfort as 2.4 [SD 1.7] and 3.1 [SD 2.1], respectively, on the VAS; while, the controls rated 4 [SD 1.6] and 5.6 [SD 1.7], respectively. The mean facial soft tissue volume change, assessed on day 1 after surgery, was 5.0 cm(3) [range: 0.2-9.2] for the study group and 15.5 cm(3) (9.3-21.55) for the controls (p = 0.00). Conclusions: Despite the small number of patients in this prospective study, 3-D based minimally invasive one-stage lateral sinus elevation resulted in favourable patient morbidity with less postoperative visible facial soft tissue volume changes.

A 5-year prospective radiographic evaluation of marginal bone levels adjacent to parallel-screw cylinder machined-neck implants and rough-surfaced microthreaded implants using digitized panoramic radiographs
Objective: The purpose of this split-mouth study was to compare macro- and microstructure implant surfaces at the marginal bone level over five years of functional loading. Materials and methods: From January to February 2006, 133 implants (70 rough-surfaced microthreaded implants and 63 machined-neck implants) were inserted in the mandible of 34 patients with Kennedy Class I residual dentitions and followed until December 2011. Marginal bone level was radiographically determined at six time points: implant placement (baseline), after the healing period, after six months, and at two years, three years, and five years follow-up. Results: Median follow-up time was 5.2 years (range: 5.1-5.4). The machined-neck group had a mean crestal bone loss of 0.5 mm (0.0-23) after the healing period, 1.1 mm (0.0-3.0) at two years follow-up, and 1.4 mm (0.0-2.9) at five years follow-up. The rough-surfaced microthreaded implant group had a mean bone loss of 0.1 mm (-0.4 to 2.0) after the healing period, 0.5 mm (0.0-2.1) at two years follow-up, and 0.7 mm (0.0-2.3) at five years follow-up. The two implant types showed significant differences in marginal bone levels. Conclusions: Rough-surfaced microthreaded design caused significantly less loss of crestal bone levels under long-term functional loading in the mandible when compared to machined-neck implants.

Influence of gender of the teaching staff on students' acceptance of a virtual implant planning course
Acceptance of new technology is influenced by a number of situational
and social factors. So far, only limited data are available on the
influence of the teaching staff's gender on the acceptance of virtual
dental implant planning by students. This study aimed at assessing the
influence of the teaching staff's gender on the acceptance of a virtual
implant planning course by male and female undergraduate dental students
and their general attitude toward implantology.
Two groups of third-year dental students (group 1, 9 males, 22 females;
group 2, 12 males, 20 females) attended a virtual dental implant
planning course. For the first group the teaching staff was all-male,
while the teaching staff was all-female for the second group. After
completion of the course the students filled in a technology acceptance
questionnaire.
An all-female teaching staff led to a degree of technology acceptance
that did not differ significantly for male and female students. When the
teaching staff was all-male, significant differences for technology
acceptance occurred between male and female students.
However, male as well as female students attributed the practice of
implantology to both genders of dentists, equally, without statistically
significant difference independent of the gender of the teaching staff.
The more evenly distributed degree of technology acceptance of students
of both genders being taught by a female staff is a favorable effect
which may be explained by the more egalitarian style of women.
Therefore, while feminization in dentistry proceeds, adequate measures
should be taken to increase the number of female teachers. (C) 2017
