Evaluation Of Clinical Success Of Preformed Aesthetic Crowns In Primary Molars - A Systematic Review

Background: Different aesthetic preformed crowns are emerging in the field to restore the decayed primary teeth as the benchmark restoration as Stainless steel crowns (SSC) do not satisfy the aesthetic needs of the patients. Aim: The aim of the systematic review is to critically analyse the existing literature on clinical success of available aesthetic preformed crowns for primary molars. Materials and Method: Detailed search strategies were carried out in Pubmed, PMC, Cochrane for identification of the studies that met the inclusion and exclusion criteria. Results: A total of 5 articles were included for analysis. 4 studies compared Zirconia crowns and 1 study compared Figaro crowns to SSCs. All the 4 studies with zirconia crowns recorded ‘high risk' of bias and the study with Figaro crowns recorded ‘low risk' of bias. Conclusion: Zirconia crowns (ZC) cannot be recommended as a replacement to SSCs in primary molars. On the other hand, more studies are required to declare Figaro crowns as a promising aesthetic replacement to SSC.
