Zirconia vs Stainless steel pediatric crowns: a literature review.

Abstract

PURPOSE The aim of this review was to assess efficacy and acceptance of aesthetic Zirconia Crowns (ZCs) compared to the traditionally employed Stainless Steel Crowns (SSCs) for primary teeth restoration. METHODS A comprehensive literature search was completed for the relevant keywords in Scopus and Medline databases. Resulting article abstracts and full texts were screened to determine final inclusion. RESULTS Eighteen articles were included from the initial search. There is still little evidence to support the use of one type of crowns over another for primary teeth, in particularly for ZCs, lately introduced in paediatric restoration. The gold standard for restoring decayed primary teeth is still represented by SSCs, despite the growing importance of the aesthetic issue related to their use. Aesthetic ZCs resulted in having adequate properties to be employed for the treatment of decayed primary teeth, such as mechanical resistance, limited plaque adhesion, wear behaviour and natural appearance. CONCLUSIONS There is still a paucity of literature clinically evaluating the efficacy of ZCs for primary teeth restoration, but they can be considered a promising alternative to SSCs. This field of research has to be more deeply explored to improve dental care in children affected by early childhood caries.
