Competency is the ability to combine evidence based knowledge, personal attitudes, and clinical skills to undertake holistic dental care [16, 17]. Competency may be of greater relevance to the dental practice than confidence level, however, the role of confidence in achieving competence should not be underestimated [18]. The quality of education and the clinical experience are essential in determining the confidence level of dental students [12]. Hence, the implementation of competencies in the curricula of undergraduate dental students was to support them to develop capacity to become safe practitioners, and as tool to update and develop curricula [3–7]. Prosthodontics and conservative dentistry are one of the core disciplines in dental practice, general practitioners usually encounter simple and complicated cases after graduation. Consequently, general dentists' practitioners should have the ability to evaluate and diagnose properly based on their understanding and knowledge, and to perform adequate procedures, especially simple cases.
Surveys are considered an essential technique to evaluate students’ perceptions and to gather information in a way that allows us, as educators, to address the successfulness and the limitations of the educational experience [19–21]. This study aims assess the perception and confidence level of final year dental students in performing essential dental procedures from core dental disciplines; Prosthodontics and Conservative dentistry. Through comparing their perceived confidence level in to two different years, 2016 and 2019.
Competencies were introduced at the first time in our dental students' curriculum in 2017, it includes multiple tasks that students are able to try to fulfil independently without supervision, for example in Prosthodontic clinics students were entitled to choose two out of multiple tasks for each semester, for example, border molding and final impression for edentulous patient, surveying of primary cast and Cr-Co RPD design, bite registration for edentulous patient. In addition, competencies were not graded which means either pass or fail, however, their fulfilment is a requirement for entering the clinical final exam at the end of the fifth year, all of that is to encourage students to do dental procedures with more confidence. Competencies is part of the 4th and the fifth year students, but most of the requirements and competencies are in the final year, because of that the fifth year students were chosen for this study.
In the present study by comparing the means of confidence level of the different tasks, students showed high confidence levels in doing simple procedures in both years, like providing patients with simple removable prosthesis (CD, Acrylic RPD, Cr-Co RPD), treatment planning for partially edentulous patients, placement of amalgam and composite filings, single crown PFM and three-units bridge. The same results reported in previous studies [18, 22–24], Murray showed in his study on final year students from New Zealand that 68.4% of students were highly confident/confident in providing patients with acrylic RPD, 59.6% in providing Full CD, 84.5% and 77.6% in providing anterior and posterior composite restoration respectively, 47.4% in conventional bridge preparation, 87.8% in Crown preparation. The same applies for the low level of confidence which was mainly in more complex procedures, like providing the patient with Immediate or Over Dentures, Implant retained prosthesis, Inlay, Onlay, Veneers and Resin Bonded Bridges. In another recent study carried in the same faculty, 97% of the fifth year students felt extremely confident in doing direct restorations while their confidence level was significantly lower in doing indirect restorations [25]. This could be related to the concept of a “safe beginner” who acts within the boundaries of their own capabilities and limitations, and knows when to request support and advice, although it has been suggested that this definition lacks both precision and detail [26]. Moreover, the only clinical training students were exposed to is during their undergrad period of time, afterwards they need to do clinical Internship for a year before they can practice independently, consequently their confidence level in more complex procedures is supposed to increase, because clinical training one of the main factors that affects students' confidence level [12, 18, 27]. The involvement of the fifth year student only in this study considered one of the limitations, because of the limited clinical training time, however, this may be considered in future research to apply the same survey after the internship period and compare results to confirm the effect of clinical on the confidence level of freshly graduate students.
To assess the effect of competencies implementation in the curricula of dental students, the confidence level in dental procedure is compared between the two years. In prosthodontic procedures there was no significant difference between the confidence levels of different procedures, except for Placing treatment plan of RPD, giving OHI's for Denture Patients, and dealing with CD post-insertion complaints were the confidence level of 2016 student was significantly higher than 2019 (P < .05). In Conservative procedures, there was no significant difference between the confidence levels of different procedures, except for Placement of the Matrix Band in Class II restoration, the confidence level of 2016 students was significantly higher than 2019. This opposite to the assumption that competencies might have a positive effect on the confidence level of students, but it is only in four out of 36 procedures tested in this survey. Achieving self-confidence is an important asset in enhancing the competencies [28], but to avoid students being over-confident they need to learn how to self-evaluate their performance, this ability to self-evaluate and achieve the real confidence needed is best achieved by independent clinical practice and implementing a proper methods for the evaluation of competencies during the undergraduate training; Kaufman et al. stated that learners should be able to analyze and assess their own performance and develop new perspectives and options [29]. The results in this study may be explained by the methods used for the evaluation of the competencies and by the set-up of competencies besides the requirements needed from fifth year students to successfully graduate. Competencies can be evaluated by a number of methods, traditional and current methods [30]. The methods used for evaluation in our dental school are traditional methods, students are entitled to do competencies during their clinical training, the task must be done independently in a specific period of time, then task is subjectively evaluated by two evaluators and the evaluation is including a short viva questions about the same procedure to assess the student knowledge. The traditional method had a major drawback in that it was subjective and occasionally inflexible, while newer criteria looks objectively at assessing the student. Consequently, competencies implantation in students' curricula must be revaluated to achieve the intended learning outcomes.
