Internal consistency of the questionnaire was determined by Cronbach's alpha and Principal component analysis was used to determine the construct of the scale.
 Result: Content Validity Index of the scale was 0.9 (S-CVI/ Avg) and alpha (Cronbach's) coefficient for the overall construct of DSQ was ≈0.83. Principal Component Analysis confirmed the internal structure of the scale and four components emerged from it.
 Conclusion: The translated nepali version of DSQ is a reliable and valid tool to determine patients’ satisfaction of dental care services based on the excellent content validation result together with robust internal reliability.
