1-year Results of Molar Incisor Hypomineralization-affected Cases Treated with Silver Modified Atraumatic Restorative Treatment: A Retrospective Study

Aim and background:Silver-modified atraumatic restorative treatment (SMART) can be an alternative method for molar incisor hypomineralization (MIH)-affected cases. The purpose of this study was to assess whether tooth location and cavity preparation affect the clinical success of MIH-affected permanent molars treated with the SMART technique. Materials and methods: Modified United States Public Health Service criteria were utilized for the analyzes. The clinical records (3, 6, and 12 months) of 19 MIH-affected cases (6–12 years; no spontaneous pain and percussion/palpation sensitivity) treated with the SMART technique were assessed. The groups were allocated based on tooth location (mandibular-maxillary) and cavity preparation (class 1–2). The Fisher exact the Chi-squared test was utilized, and the p-value < 0.05 was accepted as statistically significant. Results: Overall success rates were 94.7% at 3 and 6 months and 52.63% at 12 months. Clinical success did not differ statistically regarding location (p > 0.05). The class 1 cavity preparation group was found to be significantly more successful at the 12-month assessments (p = 0.033). Conclusion: The class of cavity preparation may affect the success of the treatment in long-term assessments. The SMART technique, especially in class 1 occlusal restorations, can be recommended as a short-term alternative to traditional treatment methods for MIH-affected cases. © The Author(s). 2024.
