A BSTRACT Context: Oral health inequalities experienced by patients, including people with disabilities (PWD), have been related to dentists’ lack of professionalism and inadequate experience in managing patients with special needs. Aims: This study investigated the impact of an extramural program involving PWD on dental students’ professionalism and students’ perception of training in managing patients with special needs. Materials and Methods: A group of 165 undergraduate dental students (year 1 to year 5) participated in a voluntary program, involving 124 visually impaired children, at a special education school in Kuala Lumpur, Malaysia. A dedicated module in oral health was developed by specialists in special care dentistry, pedodontics, and medical sciences. Dental students then participated in a semi-structured focus group interview survey to discuss perceptions of their learning experiences. Qualitative data were analyzed via thematic analysis. Results: The program had positive impact on various aspects categorized into four major domains: professional knowledge (e.g., understanding of oral-systemic-social-environmental health interaction and understanding of disability), professional skills (e.g., communication and organizational skills), professional behavior (e.g., empathy and teamwork), and value-added learning (e.g., photography and information technology skills). Students showed improved willingness to manage, and comfort in managing PWD, and expressed support for future educational programs involving this patient cohort. Conclusion: Improved knowledge, skills, attitudes, and personal values, as well as support for future programs, indicate the positive impact of extramural educational activities involving PWD in developing professionalism in patient care, while providing an opportunity for students to be exposed to managing patients with special needs.

PurposeThis study was performed to quantify the repeat rate of imaging acquisitions based on different clinical examinations, and to assess the prevalence of error types in intraoral bitewing and periapical imaging using a digital complementary metal-oxide-semiconductor (CMOS) intraoral sensor.Materials and MethodsA total of 8,030 intraoral images were retrospectively collected from 3 groups of undergraduate clinical dental students. The type of examination, stage of the procedure, and reasons for repetition were analysed and recorded. The repeat rate was calculated as the total number of repeated images divided by the total number of examinations. The weighted Cohen's kappa for inter- and intra-observer agreement was used after calibration and prior to image analysis.ResultsThe overall repeat rate on intraoral periapical images was 34.4%. A total of 1,978 repeated periapical images were from endodontic assessment, which included working length estimation (WLE), trial gutta-percha (tGP), obturation, and removal of gutta-percha (rGP). In the endodontic imaging, the highest repeat rate was from WLE (51.9%) followed by tGP (48.5%), obturation (42.2%), and rGP (35.6%). In bitewing images, the repeat rate was 15.1% and poor angulation was identified as the most common cause of error. A substantial level of intra- and interobserver agreement was achieved.ConclusionThe repeat rates in this study were relatively high, especially for certain clinical procedures, warranting training in optimization techniques and radiation protection. Repeat analysis should be performed from time to time to enhance quality assurance and hence deliver high-quality health services to patients.
