| Abstract | ||
| Objective: This clinical trial was carried out to assess the clinical efficacy of silver diamine fluoride with or without potassium iodide before high-viscosity glass ionomer restoration compared to high-viscosity glass ionomer restoration for treating deep class I carious lesions over a one-year follow-up period. Materials and methods: After partial caries removal, 42 deep class I cavities in permanent molars were allocated to one of the following groups: group 1, SDF+KI (Riva Star) (n=14); group 2, SDF (SDF, Riva Star step 1 only) (n=14); and both groups were followed by HVGI restoration (EQUIA Fil). Group 3, HVGI restorations (EQUIA Fil) (n=14). The restorations were assessed over a 12-month follow-up period using the FDI criteria. (postoperative hypersensitivity, radiographic examination, and patient’s view). Results: There were no significant differences among the three materials regarding postoperative hypersensitivity or radiographic findings (P > 0.016). However, there were statistically significant differences in the patients’ views (P < 0.016). There was a 13-fold greater risk of unacceptable score 4 (clinically unsatisfactory) for the patients’ views with the SDF compared to HVGI after 12 months (P = 0.0712). Conclusions: Applying HVGI alone or after SDF with or without KI could treat postoperative hypersensitivity in deep class I cavities after partial caries removal. Dentine treated with either SDF, SDF+KI, or HVGI could obtain successful radiographic outcomes with no signs of pulpal pathology. KI could be applied immediately after SDF to prevent black staining of the teeth and increase patient satisfaction. | ||
