Desempenho clínico do cimento de ionômero de vidro no tratamento restaurador atraumático: uma revisão da literatura

Abstract

Objective: to verify the clinical performance of glass ionomer cements (GIC) used in atraumatic restorative treatment (ART). Materials and Methods: a search was undertaken using the databases of the Virtual Health Library of Dentistry, Medline, Pubmed and Science Direct, using the subject headings "Glass Ionomer Cements", "Dental Atraumatic Restorative Treatment" and "Survival Analysis". 23 articles published in the last ten years in English or in Portuguese fulfilled the predetermined inclusion criteria. Results: most of the studies applied the ART approach in children (66%), in the primary dentition (57%) and in single and multiple surfaces (48%). The majority of studies followed the clinical performance of the restorations in the period of 12 (35%) and 24 months (35%). The high-viscosity GIC was more used and Fuji IX™ and Ketac Molar™ were the most studied brands in the ART technique. Overall, success rates of restorations ranged from 57.5% to 98% for single-surface and from 24.4% to 97.8% for multiple-surfaces. Conclusion: the association between GIC and the ART approach demonstrates a viable alternative to treat caries in primary and permanent dentition. The GIC presents superior performance for single-surface ART restorations compared to multiple-surface ART restorations in the atraumatic approach. This technique proved to be reliable and effective when compared to the conventional restorative treatment. The marginal defect and the partial or complete material loss were identified as the main causes of failure.
