Dentists knowledge, attitudes, and professional behavior toward the COVID-19 pandemic : A multisite survey of dentists perspectives
(2021) Hassan Khamis, Amar; Baqain, Zaid
Background: COVID-19 continues to affect the dental community worldwide. The authors conducted a cross-sectional electronic study using a multisite survey to examine dentists’ knowledge, attitudes, and professional behavior toward COVID-19 and the affect on their livelihood. Methods: A questionnaire was circulated via e-mail and social media platforms to dentists in North America, Europe, Eastern Mediterranean, and Western Pacific regions. It covered demographic characteristics and questions about the COVID-19 outbreak related to dentists’ levels of comfort for preventive and safety measures, provision of treatment, affect on work, and financial implications. Responses were tabulated and analyzed by means of c 2 or Fisher exact test. MannWhitney and Kruskal-Wallis tests were used to compare means. P < .05 was considered significant. Results: A total of 1,251 dentists responded. General dentists represented 63.9% of the respondents and 62.5% worked in private practice. The global score for level of comfort with the preventive measures and provisions of treatment during the COVID-19 pandemic was low (14 of 30), and differences between regions were significant (P < .01); dentists working in private practice and general dental practitioners were less comfortable (P < .01). Conclusions and Practical Implications: The respondents reported a lack of preparedness to confront a highly infectious respiratory disease. A new level of protective armamentarium in the dental operatory and updated operational guidance and policies are required, necessitating educators and regulators to ensure the delivery of knowledge and skills to oral health care providers. Dentists need to address the sustainability of their practices and have a robust business plan.
Does the use of CBCT prior to mandibular third molar surgery impact treatment planning?
(2020) Baqain, Zaid
Purpose: To investigate whether cone-beam computed tomography (CBCT) alters the treatment decision for impacted third molar surgery (M3M) when the third molars demonstrate proximity to the inferior alveolar canal (IAC) on panoramic radiography (OPG) and to examine surgeons’ confidence in the various treatment options. Methods: A retrospective study evaluating a series of randomized OPG and CBCT images and answering a set of questions regarding impacted M3M. The anatomical risk factors studied included proximity of M3M roots to the IAC, vertical relationship between the root of M3M and the IAC and interruption of the IAC cortex by M3M roots. The primary outcome variable was the treatment plan whether to observe, extract under local anesthesia, extract under general anesthesia or perform coronectomy. The secondary outcome variable was confidence in the proposed treatment plan. The Chi-square test was used to compare proportions and to test the differences in the treatment plan according to the studied independent variables. Binary logistic regression was used to determine the effect of anatomical factors. A P value < .05 was considered statistically significant. Results: The study sample consisted of 132 impacted M3M from 71 patients. There were no significant differences in the proposed treatment plan when the imaging modalities (OPG and CBCT) were compared, P>.05. Examination of CBCT enabled detecting anatomical risk factors, P<.001. Binary logistic regression demonstrated the absence of IAC cortex interruption to be the most significant determinant towards planning for extraction on OPG (OR=3.1, P<.001. Conclusions: The use of CBCT provides a better understanding of the anatomical relationship between the roots of M3M and the IAC. However, experienced surgeons dealing with impacted M3M with evidence of proximity to IAC on the OPG, can decide on the treatment modality without CBCT.
Does the Use of Cone-Beam Computed Tomography Before Mandibular Third Molar Surgery Impact Treatment Planning?
(2020) Baqain, Zaid
Purpose: We aimed to investigate whether cone-beam computed tomography (CBCT) alters the treatment decision for impacted mandibular third molar (M3M) surgery when the third molars show proximity to the inferior alveolar canal (IAC) on panoramic radiography (OPG) and to examine surgeons’ confidence in the various treatment options. Methods: We performed a retrospective study evaluating a series of randomized OPG and CBCT images and answering a set of questions regarding impacted M3Ms. The anatomic risk factors studied included the proximity of M3M roots to the IAC, vertical relationship between the M3M and the IAC, and interruption of the IAC cortex by M3M roots. The primary outcome variable was the treatment decision of whether to observe, extract under local anesthesia, extract under general anesthesia, or perform coronectomy. The secondary outcome variable was confidence in the proposed treatment plan. The c2 test was used to compare proportions and to test the differences in the treatment plan according to the studied independent variables. Binary logistic regression was used to determine the effect of anatomic factors. P < .05 was considered statistically significant. Results: The study sample consisted of 132 impacted M3Ms in 71 patients. No significant differences in the proposed treatment plan were found when the imaging modalities (OPG and CBCT) were compared (P > .05). Examination of CBCT enabled detection of anatomic risk factors (P < .001). Binary logistic regression showed the absence of IAC cortex interruption to be the most significant determinant toward planning for extraction on OPG (odds ratio, 3.1; P < .005) and on CBCT (odds ratio, 5.0; P < .001). Surgeons were more confident when planning for extraction (P < .001). Conclusions: The use of CBCT provides a better understanding of the anatomic relationship between M3M roots and the IAC. However, experienced surgeons dealing with impacted M3Ms with evidence of proximity to the IAC on OPG can decide on the treatment modality without CBCT.
The influence of insertion torque values on the failure and complication rates of dental implants: A systematic review and meta-analysis
(2021) Atieh, Momen; Baqain, Zaid; Almoselli, Mohamed
Background: The influence of using different insertion torque values on clinical and radiographic outcomes of implant therapy is unclear in the current literature. The aim of this systematic review and meta-analysis was to evaluate the implant outcomes and complications rates using high insertion torque values compared with those using regular insertion torque value levels. Methods: Randomized controlled trials (RCTs), nonrandomized controlled clinical trials (NRCCTs), prospective and retrospective cohorts were searched for in electronic databases and complemented by hand searching relevant dental journals. The risk of bias was assessed using the Cochrane Collaboration's Risk of Bias tool for randomized and nonrandomized studies. Data were analyzed using a statistical software. Results: A total of 718 studies were identified, of which, nine studies were included with 1229 dental implants in 684 participants. The meta-analysis of RCTs showed that the overall implant failure rate was not notably in favor of any insertion torque value and the difference between the two groups was not statistically significant (risk ratio 0.85; 95% confidence interval 0.07–10.52; P = 0.90). None of the RCTs was registered. The secondary analyses of non-RCTs did not either show any statistically significant difference. Overall meta-analysis did not show any significant differences in peri-implant marginal bone loss or biological/technical complications between high (≥50 Ncm) and regular insertion torque (<50 Ncm). Conclusions: There is insufficient evidence to support the use of high or regular insertion torque even with immediate implant restoration/loading. The short-term implant failure rates, changes in marginal bone level and complication rates were comparable when high or regular insertion torques were used for implant placement. The wide confidence interval indicated that results cannot be interpreted with clinically meaningful benefit for using either high or regular insertion torque.

(2021) Amir-Rad, Fatemeh; Otaki, Farah; Baqain, Zaid; Zary, Nabil; Al Halabi, Manal
Abstract: The outbreak of Coronavirus disease 2019(COVID-19) necessitated an abrupt transition from on campus, face-to-face sessions to online, distance learning in higher education institutions. The purpose of this study was to investigate the perceptions of postgraduate dental learners and instructors about the transition to distance learning, including the changes to the learning and teaching and its efficaciousness. A convergent mixed methods approach to research was utilized. All the instructors and postgraduate learners in a dental college were invited to participate in an online survey. Quantitative data was analyzed using descriptive and inferential analyses on SPSS for Windows version 25.0, and for the responses to the open-ended questions, multi-staged thematic analysis was utilized. Both groups of stakeholders: learners and instructors, were satisfied with the rapid transition to distance learning due to COVID-19. Instructors were significantly more satisfied than the learners. The stakeholders adapted well to the change. The perception of the stakeholders regarding the case based scenarios significantly influenced their level of satisfaction. As perceived by the stakeholders, the transition to distance learning entailed advantages and challenges. Going through the experience enabled the stakeholders to develop informed opinions of how best to sustain learning and teaching irrespective of how matters unfold in relation to the pandemic. In conclusion, the worldwide dental education community faced unprecedented challenges due to the onset of COVID-19. From a macro perspective, decision-makers must not miss out on the valuable opportunities, inherent in the experience, to reinforce curriculums, and maximize learning and teaching.
Self-reported adaptability among postgraduate dental learners and their instructors: Accelerated change induced by COVID-19
(2022-07) Amir-Rad, Fatemeh; Al Halabi, Manal; Baqain, Zaid; OtakiI, Farah; ZaryI, Nabil
Abstract: It is forecasted that the skills and competencies necessary for post-pandemic success in higher education need to be founded upon adaptability, coping, and Self- Regulated Learning (SRL). It is worth investigating how stakeholders perceived their adaptability and coping with the accelerated change accompanying Coronavirus Disease of 2019 (COVID-19). Accordingly, the purpose of this study was to assess the self-reported adaptability of postgraduate dental learners and their instructors in the context of abrupt transition to distance learning induced by the pandemic. This study utilized a convergent mixed methods study design. The quantitative and qualitative data were concurrently collected from instructors and learners, using a tailor-made survey of items measured with a Likert-type scale, complemented with open-ended questions. The collected datasets were independently analyzed. Descriptive and inferential analysis were conducted using the quantitative data. Qualitatively, the researchers underwent a multi-staged thematic analysis. The generated information was then integrated using a joint model analysis. The percentage of the total average of self-reported adaptability for both groups of stakeholders was 81.15%. The instructors, with a mean of satisfaction of 17.94 (±1.76), rated their adaptability significantly higher than the learners, with a mean of satisfaction of 15.66 (±2.77) (p = 0.002). The thematic analysis resulted in two interrelated themes: Self and Environment. Within the Self theme, three subthemes surfaced: Cognitions, Emotions, and Behaviors. As for the Environment theme, it encapsulated two subthemes: Enablers and Impediments. The stakeholders perceived themselves to have adapted well to the transition, and SRL appeared as a cornerstone in the adaptation to the accelerated change accompanying COVID-19. There appeared to be an interplay between the cognitions, emotions, and behaviors on the level of the self as part of the adaptation process. Also, building upon existent models of SRL, this study uncovered that the stakeholders considered the environment to play a crucial role in their adaptation process. This highlights the importance of developing a climate that remains, despite external pressures, conducive to attaining learning and teaching goals. It is also crucial for university-level mental health promotion activities to proactively foster, among learners and instructors, adaptability, building ‘academic resilience’.
