FERREIRA, Jainara Maria Soares et al. Evaluation of two restorative ionomer materials in atraumatic restorations without removing the infected denitn - preliminary study. RFO UPF [online]. 2010, vol.15, n.2, pp. 129-134. ISSN 1413-4012.

OBJECTIVE: The aim of this study was to evaluate the performance of two restorative Glass Ionomer Cements (GICs) and GIC, containing antibiotics for sealing infected dentin in atraumatic restorations of primary molars by means of clinical and radiological criteria. METHODS: In a randomized clinical trial twenty-four children (32 teeth) between the ages of 5 and 8, from both genders, separated into two groups were included: Group 1 (G1) (n = 15) restored with Maxxion R™ (FGM, Joinville) and Group 2 (G2) (n = 17) restored with Ketac Molar Easymix™ (3M-Espe, São Paulo), both linned with GIC Vidrion F™ with antibiotics (Fórmula & Ação, São Paulo). Primary molar teeth with carious lesion in the mid dentin internal sections were selected, without pulpar damage in neither clinical nor radiographic evaluations. The patients were evaluated after 30 and 90 days, using the Fisher Exact test. RESULTS: Regarding the marginal integrity, G2 received a higher percentage of satisfactory restorations when compared with G1, 73.7% x 26.3% (p < 0.05) and 73.3% x 26.7% (p > 0.05), after 30 and 90 days, respectively, by Fisher exact test. The technique used restorative returned 59.3% and 46.8% satisfactory restorations, after 30 and 90 days, respectively. There was no fistula, pain and mobility in both study groups. Radiographycally, 84.2% of the evaluated restorations by the end of the 30 days either maintained or decreased the radiotransparence and ater 90 days, 80.0%. CONCLUSION: There was a trend for higher clinical performance of the Ketac Molar Easymix™ compared to the Maxxion™ and the GIC with antibiotics represents a viable alternative as the linning material for the infected dentin.
