Self-reported preparedness of final year undergraduate dental students and interns in Saudi Arabia: a multi-institutional study.

BACKGROUND: Contemporary undergraduate dental education aims to equip the dental students with clinical competence, empathy, and professionalism to enable them to deliver safe and effective dental care to the communities. The purpose of this study was to assess the self-reported preparedness of final year dental students and interns at three Saudi dental institutions, using the pre-validated Dental Undergraduates Preparedness Assessment Scale (DU-PAS). METHODS: A cross-sectional study design was employed to assess the self-reported preparedness of the participants using the DU-PAS. Following ethics approval, a probability sampling technique was used to recruit undergraduate dental students and interns from three dental institutions in Saudi Arabia. The data was collected online on Google Forms and all participants provided their consent to participate in the study prior to providing their responses to DU-PAS. RESULTS: Responses were received from 397 participants including 171 males and 226 females yielding a response rate of 60.3%. The total mean score of the participants was 81.85 ± 13.11. Although higher scores were reported in males, the interaction between gender and DU-PAS scores were not significant. Interaction between DU-PAS scores and stage of education showed significant effect of the stage of education with interns reporting higher overall scores. The participants reported that they were able to perform most clinical procedures independently. However, low confidence was reported in performing multi-rooted endodontics, fabrication of removable dentures and orthodontic assessment. The participants also expressed their confidence in a wide range of behavioural attributes related to communication, teamworking and professionalism. However, lack of experience was noted in referral for oral cancer, interpreting research, and evaluation of new dental products using an evidence-based approach. CONCLUSION: The study provides useful insights into the self-reported preparedness of undergraduate dental students and interns in three dental institutions. While the overall preparedness of the participants was comparable to their international peers, the findings underscore the need for further enhancements to the teaching and training of undergraduate students particularly in multirooted endodontics, removable prosthodontics and orthodontics.

An insight into the clinical learning environment of dental institutes: a study in the twin cities of Pakistan.

OBJECTIVE: To assess the perceptions of dental students regarding their clinical learning environment in an urban setting. METHODS: This descriptive, cross-sectional survey was conducted from March 2020 to May 2021 after approval from the ethics review committee of Islamic International Dental College, Islamabad, Pakistan. It comprised of clinical year students, house officers and postgraduate trainees from 6 dental teaching hospitals of Rawalpindi and Islamabad. Data was collected using a pre-validated instrument assessing the dental clinical learning environment. Data was analysed using SPSS 24. RESULTS: Of the 1030 students approached, 561(54.4%) responded. Of them, 448(80%) were girls, 234(41.7%) were 3rd year students, 110(19.6%) were 4th year students, 120(21.4%) were house officers and 97(17.3%) were postgraduate trainees. Female students had a better patient attitude and were more confident in their abilities to keep up with their peers (p<0.05). The students were content with the performance of their clinical teachers, with a mean score of 70.99+/-16.0, while the lowest score of 54.67+/-22.9 was for clinical infrastructure and materials. Students of Islamabad pointed out the lack of clinical materials and maintenance of equipment but noted better research opportunities compared to their Rawalpindi counterparts (p<0.05). CONCLUSIONS: The clinical learning environment for Islamabad and Rawalpindi cities individually was good. Overall, students were satisfied with their clinical teachers, learning and training experience. Dental materials, infrastructure and maintenance factors scored the lowest.

Self-efficacy and Online Learning Readiness of Undergraduate Dental Students in Pakistan During COVID-19 Pandemic.

OBJECTIVE: To investigate the correlation between general self-efficacy and online learning readiness among Pakistani undergraduate dental students. STUDY DESIGN: Cross-sectional study. Place and Duration of the Study: Riphah International University, Islamabad, between September 2020 and March 2021. METHODOLOGY: Using cluster sampling, three dental colleges of Islamabad and Rawalpindi were selected. Electronic questionnaires were sent to 750 students. The questionnaire was comprised of two instruments, General Self-Efficacy Scale (GSES), and Online Learning Readiness Scale (OLRS). GSES had 10-items with response measurement on four-point Likert scale, while the OLRS had 18 items in five different domains measured by five-point Likert scale. Data were analysed using SPSS-23. Correlation between dependent variables was calculated using linear regression analysis. RESULTS: The response rate was 59.3% with a predominant response from female students (82.2%) compared with male students (17.8%). The majority of responses were recorded from third year students (27.9%). The year four students' scores for GSE, computer and internet self-efficacy, and self-directed learning differed significantly from other students. The overall mean GSE score was 29.37+4.57. Regression indicated a low degree of correlation between GSE and the five domains of OLRS with r2 values ranging from 0.12 to 0.32. CONCLUSION: A weak to moderate correlation was found between self-efficacy and the five dimensions of online learning readiness among Pakistani undergraduate dental students as depicted by the r-values.

Burnout level in Pakistani dentists during COVID-19 pandemic: Cross-sectional national study.

Objective: This study aims to determine the prevalence and degree of Burnout during the COVID 19 pandemic in practicing Pakistani dentists. Introduction: The COVID-19 pandemic has significantly impacted dental practices worldwide, leading to increased stress and burnout among dental practitioners. Burnout, characterized by emotional exhaustion, depersonalization, and reduced personal accomplishment, can have detrimental effects on the quality of care and patient safety. Previous studies have shown high rates of burnout among healthcare workers, including dentists. The pandemic has added new challenges, such as financial losses and increased costs due to safety protocols. Recognizing and managing burnout is crucial to mitigate its severe consequences. By understanding the prevalence of burnout in this unique context, strategies can be developed to support dental practitioners and improve their well-being. Methods: A cross-sectional study was conducted using a 22-items based validated Maslach Burnout Inventory. The study was conducted between July and September 2021. Practicing dentists across Pakistan were approached via social media platforms. The questions were answered on a 7-point Likert scale. The sums of the scores were used as the evaluation criteria. Data analysis was done using SPSS version 24. Shapiro Wilk test was used to check normality of data. Mann Whitney U and Kruskal Wallis tests were utilized to analyze the differences in the prevalence of burnout amongst the different demographic groups. A P-value of <0.05 was considered as statistically significant. Results: Total of 282 dentists responded with 116 (41.1 %) male and 166 (58.9 %) female. Majority of the respondents were postgraduate residents (24.8 %), 47.9 % of the practitioners had 0-3 years of work experience, 48.6 % of the respondents were practicing in the Federal region, and 62.8 % of the subjects were between the age of 25-34. Emotional exhaustion was the major dimension of burnout identified in our study with 47.5 % of the population reporting high levels, while only 23 % of the population showed high levels of depersonalization and 29.4 % showed low sense of personal accomplishment. Conclusion: This study indicates a considerable percentage of burnout in the chosen sample. The mean scores of Emotional Exhaustion, Depersonalization and Diminished sense of personal accomplishment were all found to be in the moderate range, and that appropriate measures should be taken to manage it.

Frequency of middle mesial canal in mandibular first molars and its association with various anatomic variables.

This study aimed to determine the frequency of the middle mesial canal in the mandibular first molars and its association with various anatomical features. Two experienced endodontists evaluated 149 CBCT images, containing n = 298 mandibular first molars and n = 298 mandibular second molars. Binary logistic regression was used to explore the relationship between the presence of middle mesial canal and other independent variables. The middle mesial canal was found in 7.7% (n = 23) of mandibular first molars and 11.4% of which exhibited adjacent C-shaped mandibular second molars. The presence of an adjacent C-shaped mandibular second molar was associated with a 3 times increased likelihood of finding a middle mesial canal (P = 0.048, OR: 3.108) in mandibular first molars. The middle mesial canal is an uncommon finding with a rare occurrence of bilateral presence in mandibular molars; however, an adjacent C-molar is an important predictor of middle mesial canal presence.

Automated feature detection in dental periapical radiographs by using deep learning.

OBJECTIVE: The aim of this study was to investigate automated feature detection, segmentation, and quantification of common findings in periapical radiographs (PRs) by using deep learning (DL)-based computer vision techniques. STUDY DESIGN: Caries, alveolar bone recession, and interradicular radiolucencies were labeled on 206 digital PRs by 3 specialists (2 oral pathologists and 1 endodontist). The PRs were divided into "Training and Validation" and "Test" data sets consisting of 176 and 30 PRs, respectively. Multiple transformations of image data were used as input to deep neural networks during training. Outcomes of existing and purpose-built DL architectures were compared to identify the most suitable architecture for automated analysis. RESULTS: The U-Net architecture and its variant significantly outperformed Xnet and SegNet in all metrics. The overall best performing architecture on the validation data set was "U-Net+Densenet121" (mean intersection over union [mIoU] = 0.501; Dice coefficient = 0.569). Performance of all architectures degraded on the "Test" data set; "U-Net" delivered the best performance (mIoU = 0.402; Dice coefficient = 0.453). Interradicular radiolucencies were the most difficult to segment. CONCLUSIONS: DL has potential for automated analysis of PRs but warrants further research. Among existing off-the-shelf architectures, U-Net and its variants delivered the best performance. Further performance gains can be obtained via purpose-built architectures and a larger multicentric cohort.

Pott puffy tumor: a rare complication of sinusitis.

Pott puffy tumor, a rare complication of sinusitis in adults, appears as a localized swelling over the frontal region or forehead. This swelling is due to a subperiosteal abscess resulting from osteomyelitis of the underlying frontal bone. This condition may be associated with an epidural purulent collection, subdural empyema, and intracerebral abscess. This entity is rare--even forgotten--since the advent of modern powerful antibiotics. A 27-year-old male was referred to ENT OPD with forehead swelling, fever and headache. The patient had mooth doughy swelling of the foreheadwith surrounding cellulitis and swelling spreading to the orbits as periorbital odema. On examination, patient had very poor oral hygiene with severe dental caries. CT with contrast conformed pansinusitis with erosion of frontal bone and abscess. An early recognition of this forgotten complication of sinusitis will help avoid severe neurological sequelae and increased morbidity and mortality.
