Abstract

Aim: This research aims to evaluate the difference between what orthodontic patients expect and perceive regarding the quality of dental services at the Postgraduate Centre, Kulliyyah of Dentistry, International Islamic University Malaysia. Methods: A cross-sectional study was conducted involving 202 orthodontic patients selected through convenience sampling. A modified 20-item SERVQUAL questionnaire was used to measure patients’ expectations before treatment and their perceptions after receiving care. Data were collected during the same visit, and analysis was performed using SPSS version 28, applying Wilcoxon’s signed-rank test to evaluate differences between expectations and perception scores. P-value<0.05 considered as significant. Results: Significant differences were found between patients’ expectations and perceptions (P<0.05), except for “waiting time” (Q3), “visually appealing facilities” (Q4), “up-to-date equipment” (Q5), and “toilet cleanliness” (Q20). The highest satisfaction was reported for “neat appearance” (Q6), “politeness” (Q10), “caring attitude” (Q7) and “prompt treatment” (Q15). The smallest satisfaction gaps were observed for “toilet cleanliness” (Q20), “waiting time” (Q3), “up-to-date equipment” (Q5), “visually appealing facilities” (Q4), and “clear explanation of dental issues” (Q12). Overall, patients’ perceptions exceeded expectations across all dimensions, with positive gaps, though tangibles (D1) and assurance (D4) showed the least positive differences. Conclusion: The results indicated that orthodontic patients were generally satisfied with the quality of care received. Regular service evaluation and focused improvements, particularly in tangible and assurance aspects, are recommended to ensure high levels of patient satisfaction
