Abstract:New paradigms of Brazilian dental education involve orthodontics in the context of generalist professional formation, encouraging the recognition of teaching reality of this discipline in undergraduate courses in dentistry. This article discusses the orthodontics discipline in Brazilian dentistry undergraduate courses to identify the number of semesters offered, nomenclature, insertion model, content format and the performance of clinical practice in undergraduate education and its association with characteriz… Show more
“…The survey form design was based on a previous study 31 and a pilot phase involving 5 professors of the course of endodontics. We composed 23 questions to cover four categories: Data related to the Institution/School/Predoctoral dental programme/endodontic course; Data related to faculty responsible for teaching in the endodontic course; Information related to the methodology used for the teaching of endodontics; Training of the general dentist by a written faculty assessment.…”
Introduction
Technological resources are considered important for the practice and training in endodontics. It is not yet clear the extent of the insertion of these resources in predoctoral dental programmes and the effect of such resources to the general dentist training.
Aim
To evaluate the faculty perception regarding the insertion of technological resources, particularly rotary instruments, and the impact of such resources to the student's learning process graded at the end of predoctoral dental programmes in Brazil by the National Students Performance Exam (ENADE).
Methods
The endodontic department faculties in all 205 programmes that participated in the 2016 ENADE received a questionnaire by email. The institution, faculty credentials, and insertion of technologies in each programme were described, and an association between these data and the ENADE score was tested.
Results
149 educators (72.7%) answered the form. From this total, 73.2% of them were from private institutions and 26.8% from public ones. Educators mix manual and rotary instrumentation to treat selected patients in 47.7% of the programmes. Most educators (89.9%) consider the utilisation of technology in endodontics as positive. Whilst there was not a significant association between the use of rotary instrumentation and better performance in ENADE, there was a significant association between the performance and the supply of special instruments by the institutions.
Conclusion
These results show that even though most faculties consider the insertion of technologies as positive, the factor that caused a significant impact to the training of the general dentist is the general infrastructure of the institutions.

“…Inaccurate measures taken by orthodontists for diagnostics, whether due to inability, lack of knowledge at some stage of dental treatment, or even limitations in their basic training, 29 can generate clinical, ethical and legal questioning of their function, 30 as the number of litigations against orthodontists have been increasing. 31 …”
Background. Software programs for visualization and analysis of digital orthodontic models, apart from presenting the
necessary features for diagnosis and treatment planning, also need to be user-friendly. This characteristic refers to software’ usability, a measure that evaluates how easy it is to use it is by a specific group of professionals. The aim of this study was to compare the usability of free available versions of two software programs for visualization and analysis of digital orthodontic models.
Methods. Digimodel® and OrthoCAD® usability were evaluated through their interface analysis and executing the following procedures: malocclusion classification and models analysis (arch-length and tooth-size discrepancies).
Results. Digimodel® and OrthoCAD® software programs had an installer only for Windows platform, occupied less than 110 megabytes of virtual space and only read files from their respective manufacturers. None possessed Portuguese as a language option. Both allowed visualization of the models in different axes through options present in initial screen, at a click. For model analysis, both software programs required to measure tooth to tooth and performed necessary calculations automatically. However, OrthoCAD® software program was less intuitive because the option for these actions was among several others, within menus, which could cause confusion during navigation. In addition, the marking of points did not always obey the clicked site.
Conclusion. The free access version of the evaluated software programs exhibited usability limitations related to language, supported file format and even the model analysis execution for orthodontic diagnosis. Although OrthoCAD® was inferior, both did not meet orthodontists’ clinical demand against these factors in the evaluated versions.
Polymers have been employed for the development of medical devices and
implants as some of them are biocompatible. Synthetic procedures and extraction
techniques have allowed the obtention of different polymers, classified in this chapter
as synthetic and natural polymers. In the process of synthesis of the polymer, its
properties can be modulated to obtain more flexible or thermostable materials, non toxic or transparent, depending on the desired properties of the final product. A wide
range of polymers have been used for the manufacturing of catheters, valves, tubes, and
other medical devices; therefore, in this chapter, there is a brief description of some of
them, their chemical structure and properties, and finally, their application in medicine
is shown.
