Examining the factors of patient dissatisfaction after gum transplantation can lead to an increase in the therapist's insight into the factors that affect patients' satisfaction and the best implementation of treatment. This study aimed to specify the level of patient satisfaction with gum grafting. In this descriptive-cross-sectional study, 63 patients who underwent free gingival grafting and sub-epithelial connective tissue were randomly evaluated, and their choice and level of satisfaction with gingival grafting were evaluated by a researcher-made questionnaire. The data was analyzed using SPSS version 23 software and ANOVA, t-test, and Spearman's correlation coefficient statistical tests (α = 0.05). Based on the findings of the study, the overall satisfaction score of the patients was calculated as 3.47 ± 0.64, which was in the average satisfaction range. There was no remarkable difference in the mean satisfaction scores of female and male subjects (P > 0.05). The highest level of satisfaction was associated with “giving necessary explanations by the doctor about the process of gum transplant surgery at the beginning” and “Gum transplant surgery has made it easier for me to maintain hygiene.” In addition, the lowest satisfaction level was associated with “duration of pain after surgery” and “color matching of the transplanted gums with adjacent gums.” According to the results of this study, the patients who received gum transplants had relatively favorable satisfaction.
