Parental satisfaction of beauty in Silver Diamine Fluoride (SDF) followed by Resin-modified Glass Ionomer Cement Restoration (RMGI) compared to RMGI restoration was investigated in this cross-sectional study. The 3-12 years old patients from the dental clinic department of Nong sue hospital, Pathum-Thani, who had one or more cavitated carious lesion (ICDAS score 5) on posterior primary teeth. There were 43 patients who were the participant in this study (Dec 2021 – Jan 2022). The 13 patients were excluded from this study by exclusion criteria. The remaining patients followed the inclusion criteria were randomly assigned to SDF combined with RMGI restoration for 15 parents and RMGI restoration only as a control treatment for 15 parents. All carious lesions were collected by using Atraumatic Restorative Treatment (ART) or Interim therapeutic restoration (ITR) by an operator, followed by the SDF combined with RMGI restoration or the RMGI restoration. The 5 score Likert scale was used to evaluate the parental esthetic satisfaction to the restoration at periodic recall 2 weeks by the questionnaires. The results showed that at two weeks after the operation, the mean of parental satisfaction on SDF combined with RMGI restoration group and RMGI restoration group were 4.7 and 4.6667 respectively. The Mann-Whitney U-test was used to analyze, the result was parental satisfaction on SDF combined with RMGI restoration group had no statistically significant difference in parental satisfaction in tooth discoloration after treatment compare with RMGI restoration group (p=1.000). Treatment with SDF with RMGI together was well accepted by parents. Postoperative signs and symptoms perceived by a few parents included pain, gingival swelling or irritation, and bad mouth odor, which were less likely to relate to SDF application. Black staining after SDF treatment, which is the major disadvantage of this treatment, did not affect parental satisfaction to the degree that had been feared.
