Musculoskeletal disorders and work ability among dentists and dental students in Finland.

BACKGROUND: Musculoskeletal disorders are leading causes for long sickness absences and early retirement. Dental work is physically strenuous, and many studies have shown a relation between work-related MSDs and dentistry. However, fewer studies have focused on how these conditions affect the work ability of dentists. OBJECTIVE: This study aimed to reveal the relationship between MSD, work ability and sickness absences in Finnish dentists and dental students. METHODS: A questionnaire was sent to 1200 dental workers and students. It inquired of age, gender, use of dental loupes, physical exercise, use of health care, and site, length and frequency of musculoskeletal complaints. Work ability was assessed with four parameters: work ability score (WAS), future work ability (FWA), self-estimation of MSD-related work disability, and sickness absence days. RESULTS: The questionnaire gained 255 responses (response rate 21%). The majority (90%) of the respondents had experienced MSD during the past year but only eleven percent of them had been on sick leave. MSDs correlated significantly with WAS, FWA and MSD-related work disability. Results remained significant even age adjusted. Age was a strong predictor of declined work ability, but gender, physical exercise or dental loupe use did not have a significant impact. CONCLUSIONS: Despite all the ergonomic advances in modern dentistry, the occurrence of MSD symptoms is still high. MSDs seem to affect dentists' work ability significantly, but amount of sickness absence is relatively low, which may indicate a high level of presenteeism.

Dental students' perceptions of simultaneous live and online OSCEs during the COVID-19 pandemic.

INTRODUCTION: The Objective Structured Clinical Examination (OSCE) is a valid, reliable and reproducible assessment method traditionally carried out as a live examination but recently also provided online. The aim was to compare any differences in the perceptions of dental students participating in online and live OSCE using mixed methods. MATERIALS AND METHODS: All Finnish fourth-year undergraduate dental students (n = 172) attended the exam in April 2021. Due to the COVID-19 pandemic, the official administrative restrictions in teaching in universities still existed in April 2021. By the time of the national OSCE, the pandemic situation varied in different parts of the country. Therefore, two of the universities conducted a live OSCE and two an online version of the OSCE. Data were collected after the OSCE using a voluntary anonymous electronic questionnaire with multiple-choice and open-ended questions (response rate 58%). Differences between the OSCE versions were analysed using the Mann-Whitney U test and open answers with qualitative content analysis. RESULTS: The students considered both types of OSCE good in general. The main differences were found concerned adequate time allocation and overall technical implementation, in favour of the live OSCE. While a qualitative analysis revealed exam anxiety as the most often mentioned negative issue, overall, comments were positive. CONCLUSION: Variation in the assessments between different question entities seemed to be wider than between the implemented OSCE versions. Time management in the OSCE should be further developed by managing the assignment of tasks.

Examination performance of dentistry students during the COVID-19 pandemic.

CONCLUSIONS: Our results imply that online teaching did not systematically improve or worsen the examination performance of undergraduate students of dentistry. Our findings have important policy implications for educational practices in the future. The observed annual grade variation might reflect the effectiveness of remote teaching, changes in students' performance, or non-systematic grading. MATERIALS AND METHODS: Using administrative data from the University of Helsinki, the examination performance during the years 2018 and 2019 was compared with that of 2020. OBJECTIVE: The global COVID-19 pandemic has led to an increase in remote teaching and online assessment in higher education. The examination performance of undergraduate students of dentistry was evaluated to assess any possible association between the altered learning environment and learners' performance. RESULTS: In 16 out of 22 courses (73%) taught remotely during the pandemic, a statistically significant difference (p < .05) between the awarded grades was observed, as compared to the two previous years. Annual variation in examination grades was common even before the onset of remote teaching, but more so after it. The grade variation during the pandemic was nearly as prevalent towards falling grades (26%) as towards rising grades (36%), implying a multifactorial cause possibly unrelated to remote teaching.

Finnish dentists' experiences with foreign-background patients-a qualitative study.

OBJECTIVE: The population in many countries is becoming more diverse. The number of people from foreign backgrounds is growing in Finland as well. The aim of this study was to better understand how the foreign background of a patient affects the dentist's work. METHODS: The research was carried out as a semi-structured interview. Six dentists from Helsinki municipality public dental care were interviewed between December 2019 and January 2020. After the interviews were transcribed verbatim, two members of the research group read individually the interviews to find emerging themes. RESULTS: The most common problems that arose in the interviews were problems within communication and interpretation. Periodontal diseases and the importance of self-care in treating them were observed to be unfamiliar to many foreign-background patients. The dentists also noticed different expressions of pain among foreign-background patients compared with native Finnish patients. The interviewed dentists thought that the length of time a patient had lived in Finland affected the experienced difficulties and the prejudice that the patients and dentists faced. CONCLUSION: In this qualitative research, we were able to identify some of the common difficulties that the dentists experience while treating patients from foreign backgrounds, despite the small number of participants.

The impact of orthodontic treatment on choosing a career in dentistry.

INTRODUCTION: Many studies, globally, have aimed at elucidating reasons to choose a career in dentistry. The most common motives found are reasonable working hours and aspiration to help. The aim of this study was to explore whether eventual past personal experience of orthodontic treatment and particularly the interpersonal skills of the treating orthodontist are of significance in this respect. MATERIALS AND METHODS: An electronic questionnaire, consisting of multiple choice and descriptive questions about dental history and experiences in dental care, was sent to dental and, as controls, psychology students within the same Faculty of Medicine, University of Helsinki, Finland. The answers between the two groups were compared and differences tested statistically. RESULTS: The questionnaire was answered by 143 (46.0%) dental students and 94 (17.6%) psychology students. Dental students, compared to psychology students, had more positive views of their dentition and dental treatment in general (p = 0.000). Amongst participants, 47.9% of dental students and 57.4% of psychology students had received orthodontic treatment. Of those, dental students had perceived their orthodontic treatment as less painful (p = 0.001) and less uncomfortable (p = 0.000) than psychology students. Moreover, dental students reported more often experiences of orthodontist taking into account their situation in life during treatment (p = 0.011) and gave more positive descriptions of the orthodontist's interpersonal skills (p = 0.031). CONCLUSIONS: Dental students, compared to psychology students, had statistically significantly more positive personal experiences related to dentistry and orthodontics, supporting our hypothesis that positive experiences with orthodontic treatment likely increase the probability of choosing dentistry as the future career.

Biomedical Courses Should Also Be Designed for Dental Students: The Perceptions of Dental Students.

INTRODUCTION: It can be challenging integrating biomedical sciences into dentistry programs. The aim was to examine students' perceptions of how joint biomedical courses with medical students and courses tailored for dental students supported their clinical studies. MATERIALS AND METHODS: The target group was clinical phase dental students. Cross-sectional survey data were collected using a questionnaire, which consisted of questions covering biomedical and clinical study content and learning methods. RESULTS: A total of 110 (82%) students completed the survey. Students had difficulty recognising the relevance of joint biomedical courses for clinical work, but when the link was clear, their interest in the content increased. The closer the respondents were to graduation, the less relevance they expressed the biomedical sciences had. Almost all students (95%) wanted more dental content for the early study years. DISCUSSION: The student perspective provides valuable information for the development of biomedical courses. Students should be offered customised courses that include dental content and perspectives on clinical work, whenever suitable to the didactic content of the basic science course. Our study shows that the dental perspective needs greater integration with the biomedical content. This also supports interprofessional learning and appreciation for the other field's contribution to human health.

The reproduction of gender differences in early career choices and professional identity of young dentist in Finland.

INTRODUCTION: For over the last 20 years, approximately 70% of working dentists in Finland have been women. However, there is internal division of the profession along gender lines. Female dentists work more often in the public sector and male dentists in the private sector. The aim of this study was to investigate the gender differences in young dentists' early career choices, specialization plans, values and perceptions of professional identity. MATERIALS AND METHODS: The data were taken from a national e-mail questionnaire study called "Young Dentist," which was sent to 458 dentists who had received their licence to practise dentistry in 2014-2016 from all four universities with dental curricula in Finland. A total of 52% young dentists (n = 238) answered the questionnaire. RESULTS AND DISCUSSION: The results indicated that whereas female dentists were more likely to perceive themselves as comforters, social workers and health promoters, male dentists tended to perceive themselves as technicians. These professional identities were interrelated with early-stage career choices in which female dentists worked more often in the public than in the private sector when compared to male dentists. There were also clear gender differences in the importance of values and the specialization plans of the young dentists. CONCLUSION: Young dentists in Finland make career choices and develop professional identity in accordance with the attributes traditionally associated with cultural ideals related to femininity and masculinity.

Modification of national OSCE due to COVID-19 - Implementation and students' feedback.

AIM: The aims were to describe the development of a modified national online OSCE during COVID-19 and assess related student feedback. MATERIAL AND METHODS: The modified online OSCE comprising of eight question entities was organised simultaneously in all four dental institutes of Finland using the Moodle virtual learning environment. All fourth-year students (n = 179) attended the examination online at home. Student feedback was collected via an anonymous questionnaire with multiple-choice questions and open-ended questions concerning attitudes towards the modified online OSCE, as well as content and usability of the question entities in the examination. Means and standard deviations were calculated for multiple-choice questions. Content analysis was used for open-ended questions. RESULTS: Of 179 students, 119 (66%) consented to the study. Students experienced they had received adequate information (mean 3.8; SD 1.2), had a positive attitude before the examination (4.0; 1.0) and found the practice test useful (3.7; 1.1) (range 1-5). Technical implementation (2.7; 0.7) and the difficulty of the questions (2.9; 0.6) (range 1-4) were found to be good. The teaching students received during their studies was sufficient (3.2; 0.5) (range 1-4). Content (mean 3.2; 0.4) and usability (2.9; 0.4) of the question entities were good (range 1-4). The themes arising from open-ended questions were importance and practicality of the topic (in questions) in relation to the work of a dentist and gratitude for the rapid conversion of the OSCE into an online examination despite COVID-19. The themes arising from negative experiences included difficulties in completing the examination within the time allocated, and dissatisfaction with the model answers provided after the examination. CONCLUSION: The positive student feedback towards the modified online OSCE encourages including an online examination to complement the traditional OSCE.

Pinhole osteotomy in distraction osteogenesis - a technical note.

A new surgical approach for performing the mandibular osteotomy for distraction osteogenesis is described. In order to minimize trauma to bone caused by the osteotomy - and adjacent soft tissue - caused by excessive stretching - an additional transbuccal pinhole incision is made. The shaft of the saw blade is passed through this incision. This allows a precise cut of the mandibular ramus at the planned angle and easy guidance of the saw during the procedure. The method can be used both with extraoral or intraoral distraction devices in children and adults.
