Self-reported dental student stressors and experiences during the COVID-19 pandemic

OBJECTIVE

To compare the influence of coronavirus disease 2019 (COVID-19) pandemic on the student reported outcomes among dental students reading/studying different courses offered in the only dental school in Malta.

MATERIALS AND METHODS

An anonymous questionnaire consisting of 13 closed-ended and open-ended questions was sent to all students (n = 97) at the Faculty of Dental Surgery at the University of Malta. Emergent themes from open-ended questions were identified and tallied. Since data were classified as categorical ranks, nonparametric tests were used to compare variables among the different courses, years of study, preclinical/clinical students, and gender categories.

RESULTS

Dental technology students were significantly less stressed about contracting COVID-19 (P = 0.005) and regarding lack of preparation due to inability to physically go to the library (P = 0.019). Female students reported significantly more anxiety for the following factors: "feeling anxious all the time" (P = 0.033), "worried about contracting COVID-19'" (P = 0.012), "worried that a family member may contract COVID-19'" (P = 0.048), "more anxious about exams this year because of the challenges we are facing" (P = 0.029), and "concern about losing manual dexterity skills" (P = 0.038). Qualitative data gathered show considerable stress reported by students regarding changes in examination processes and formats and lack of timely communication.

CONCLUSION

Students were greatly affected by the COVID-19 pandemic and this caused fear of losing their manual dexterity skills, anxiety related to its consequences on their long-term plans, and anxiety related to the examinations. Dental schools in turn should adapt rapidly and customize changes that are specific to the individual student cohort and their stage of training.

Undergraduate students' evaluation and reflections on a gerodontology programme

INTRODUCTION

Many societies have observed a steady increase of many older adults living longer due to advancements in health and standard of living. The dental team requires specialised training in gerodontology to better prepare for the future needs of the elderly patients. It is the aim of this study to report the undergraduate students' activities and perspectives on their work experience in a geriatric residence.

MATERIALS AND METHODS

An anonymous online questionnaire on the theoretical and practical aspects of training was sent to students in dentistry and dental hygiene (DH) undergraduate courses. Students were also invited to discuss their experiences. Data of clinical treatment performed by the students were collected. The number of clinical hours of student exposure to patients was measured.

RESULTS

Completion of the questionnaire was high (90%). Both DH and dentistry students have in excess of 100 hours/y of clinical practice. Overall students rate their experience as a positive one that enriches patients' well-being. However they identify barriers to oral health and experience challenges related to their clinical work and level of competence (Kruskal-Wallis Test P < .05).

CONCLUSIONS

study participants were strongly motivated towards the management of frail older adults and cognisant of the barriers and constraints of achieving a reasonable level of oral health. Gerodontology programmes should be adaptable in order to create the appropriate environment and address socio-emotional challenges experienced by students.

Assessment of CD-105 as an Angiogenic Modulator in Odontogenic Myxomas and Dental Follicles

Aim Odontogenic myxoma is a benign intraosseous neoplasm of the jaws, with a locally aggressive behavior and a high recurrence rate. CD-105 is a homodimeric cell membrane glycoprotein and is a component of the TGF-β1 growth factor receptor complex that modulates angiogenesis by regulating the proliferation, differentiation and cellular migration. The aim of this study is to quantify the microvascular density of the odontogenic myxoma based on the expression of CD-105. Materials and Methods The analysis included 18 odontogenic myxoma and 18 dental follicles as controls. A standard immunohistochemical procedure was performed with the CD-105 antibody. Five representative fields (40×) of the odontogenic myxoma and the dental follicles were selected to determine the microvascular density, which was then followed by a descriptive and comparative statistical analysis. Results Dental follicles presented a significantly higher microvascular density compared with odontogenic myxoma (P = .001). The odontogenic myxoma smaller than 3 cm showed a greater microvascular density than those larger than 3 cm in size (P > .05), and the microvascular density was lower in large odontogenic myxomas as compared with the dental follicles (P = .003). Conclusion A weaker expression of CD-105 in odontogenic myxoma might indicate a lower angiogenic activity, suggesting that vascular proliferation has a limited role in the growth mechanisms and in the aggressive behavior of this neoplasm.
