Longevidade dos diferentes tipos de materiais restauradores para molares decíduos após remoção seletiva de tecido cariado: uma revisão integrativa da literatura

Abstract

Considering the variety of restorative materials available on the market and the growing practice of minimal intervention dentistry, it is important for the dentist to know the longevity of these materials in primary teeth when used through selective carious tissue removal (SCTR). Thus, the aim of this study was to review the literature to compare restorative materials and analyze the longevity of these restorations after selective removal of carious tissue, considering deciduous molars with class I and II cavities. This is an integrative literature review, with the data search performed in February 2022, using the PubMed database. The inclusion criteria were clinical trials that compared restorative materials in class I and/or II cavities of deciduous molar teeth, which used the SRCT and which evaluated the longevity of the restorations. The selection and screening of studies was performed by three independent researchers and the references found were managed by the EndNote Web software. The search strategy resulted in 725 articles, with only 13 studies meeting the inclusion criteria. The year of publication ranged from 2006 to 2021 and all were randomized clinical trials. The materials used were high viscosity glass ionomer cement (GIC), conventional GIC, resin-modified GIC, GIC with Amalgam particles, Glass Carbomer Cement, Compomer, Composite resins and bulk-fill composite resin with Giomer technology. At 6 months of follow-up, the group that presented the greatest longevity was the GIC Fuji IX with 98.3% of successful restorations for Class I. Among the restorations that presented the greatest longevity at the end of the 12-month follow-up, the group with the highest percentage was GIC Ketac Nano 100, with 98% of successful Class I restorations, followed by Amalgomer CR, with 97%. The study with the longest follow-up showed better results for the GIC Vitro Molar (86.8%) after 4 years. Among the types of class evaluations, class I was associated with greater longevity of restorations compared to class II cavities. It is concluded that restorations performed with GIC using an SRCT may vary according to the brand of material used, as well as the type of cavity to be restored.
