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 MIHaffected 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 MIHaffected cases.
