Clinical versus Dental Laboratory Survey Regarding Modern Fixed Implant Supported Prosthetic in Romania

(1) Background: The success of prosthetic treatment with implant support depends on the combined effort of the team doctor-technician, each of them being responsible for the validation of execution stages. (2) Methods: we composed an online questionnaire with 18 multiple choice questions, using the Google Forms application. It was filled out by an equal number of prosthodontic specialists and dental technicians. Differences and associations were evaluated by Likelihood Ratio test, Linear by Linear association test, Kruskal-Wallis H test, Pearson Chi-Square test and the Fisher’s Exact test. (3) Results: Differences and similarities were found between the statements of prosthodontic specialists and dental technicians. Years of experience are correlated with the number of restorations, impression techniques and types of restoration (p ≤ 0.05). Similar answers for both groups were registered for preferred screw retained type of prosthetic abutment and most frequently reported complications. (4) Conclusions: The different perspectives of the two members of the prosthodontic team regarding the leading role in the treatment plan, type of abutment, impression technique and prosthetic design of implant fixed restorations has been revealed in our study. Similar education curricula and standards for continuing training courses after graduation are necessary for prosthodontic specialists and technicians in Romania.

Assessment of the Knowledge about Routine Laboratory Procedures in Fabrication of Fixed Dental Prostheses amongst Dental Laboratories in Western Maharashtra Region

BACKGROUND The success of fixed dental prosthesis (FDPs) delivered to the patients depends upon the implementation of appropriate laboratory procedures and dental materials which are required during fabrication of that prosthesis. Inappropriate technique during its fabrication may not always hamper the esthetic end results or fit, but may also hamper the longevity as well. Thus, knowledge about the dental materials as well as the basic laboratory procedures among the dental laboratories should be regularly assessed to assure good quality work. This survey was conducted to assess the knowledge among laboratory technicians regarding the routinely used laboratory procedures and materials for fabrication of FDPs in dental laboratories in Western Maharashtra region with the help of a validated questionnaire. METHODS An electronic survey was conducted with the help of a validated questionnaire that was circulated to 49 laboratories in Western Maharashtra region. The feedback was gathered from laboratory technicians and was then statistically analysed to achieve the objectives of the study. RESULTS 48.8 % of laboratories confirmed that technicians working for them were registered under the state council. 51 % agreed that they only used dental materials that were American Dental Association (ADA) specified. The most common gypsum product for pouring of impressions was dental stone. 65.9 % of the technicians agreed that they inspected the cast before starting the fabrication procedure. Die preparation and ditching procedure was done by 52.9 % and 35.7 % laboratories respectively. Only 38.1 % agreed of using beryllium free alloy ingots; in 66.7 % laboratories, ceramic work was carried out in a separate ceramic room with 76.2 % having adequate ventilation provisions. CONCLUSIONS Response of technicians in Western Maharashtra region regarding their knowledge about basic laboratory procedures in FDP fabrication indicates several areas of weakness. Avoiding such inadequacy in laboratories can significantly reduce FDP failure rates. KEY WORDS Fixed Dental Prosthesis, Dental Laboratory, Survey

Correlational Study of Student Perceptions of their Undergraduate Laboratory Environment with respect to Gender and Major

The science laboratory learning environment has been a distinctive area in science education since the 19th century. Unfortunately, students are generally not aware of what science instructors expect from laboratory experiences, and far too often, the undergraduate science laboratory curriculum lacks explicit, well-defined goals. Science instructors assume that they have created their laboratory curriculum in such a way as to reflect an ideal science instructional laboratory, but students may not recognize this. What previous studies do not indicate is the extent to which students understand the laboratory goals for instruction as intended by the instructors. This study, therefore, using a quantitative design, examined undergraduate science major (biology, chemistry, and physics) and non-major students’, and female and male perceptions of their science instructional laboratory with respect to instructors’ goals for the laboratory. Data was collected via the Student Perceptions of the College Instructional Laboratory Survey (SPCILS) at a Midwestern University in the USA. The findings suggest that, on the whole, students perceive their instructional labs much as intended by their instructors. Female and male students were just as likely to view their instructional laboratories as intended by the instructors. Moreover, the study found no differences between science majors and non-majors. This study provides baseline data for future qualitative studies about how major and gender might be impacting students’ laboratory experiences in ways beyond what was measured on this survey. Our research was done at a teaching-oriented, midsized university. It would thus be appropriate for similar investigations to be carried out at a research-oriented university.

IDENTIFIKASI HAMBATAN PELAKSANAAN PRAKTIKUM BIOLOGI DAN ALTERNATIF SOLUSINYA DI SMA NEGERI 1 MOGA

This study aims to determine the barriers to carrying out practical activities and find alternative solutions that can overcome them through a literature review. The method used is the survey method and literature review. Laboratory survey results, student opinions, and teacher opinions show that obstacles in carrying out practical activities include the lack of laboratory facilities, the lack of supporting facilities and infrastructure, the absence of laboratory assistants, insufficient time allocation. An alternative solution that teachers can do is to use a virtual laboratory. Virtual practicum is a series of laboratory tools in the form of interactive multimedia-based computer software, which is operated by a computer and can simulate activities in the laboratory as if the user were in a real laboratory. Therefore, virtual practicum as a product of technological progress can be an alternative solution to overcome these obstacles.

Clinicoepidemiological features of tick-borne encephalitis course in Perm krai

Objective. The incidence rate of tick-borne encephalitis in Perm Krai annually exceeds that in the Russian Federation by several times, and therefore, the aim of the study was to reveal the clinical and epidemiological characteristics of the course of infection. Materials and methods. A continuous retrospective clinical and laboratory survey including 314 adult patients admitted to the Perm Regional Clinical Infectious Diseases Hospital in 2014-2019 was carried out. Results. The following features were revealed: the disease is diagnosed more often in persons over 41 years old, infection mainly occurs when visiting the forest and park areas. That is why, it is necessary to reduce the number of infection carriers. In every fifth patient, the disease is characterized by the development of an inapparent form, as well as mixed infection in association with pathogens circulating in ticks in the territory of Western Ural ticks. Conclusions. In 45.9 % of cases, the infection has a moderate and severe course, involving not only meninges but also the brain substances into the pathological process that requires early diagnosis and timely adequate therapy.
