Clinical Performance of Indirect Composite Onlays as Esthetic Alternative to Stainless Steel Crowns for Rehabilitation of a Large Carious Primary Molar

Abstract

Objective: The aim of the present study was to evaluate the clinical performance of indirect resin composite onlays (IRC onlay) compared to stainless steel crowns (SSCs), as an esthetic alternative for rehabilitation of extensively carious primary molars.

Study design: Fifty pediatric patients each received either IRC onlay or SSC randomly on extensively carious endodontically treated primary molars. All the restorations were evaluated at baseline and then every 6 months till 36 months using 'modified FDI criteria' for retention, marginal integrity, occlusion, proximal contact, secondary caries and gingival health. The dental chair side treatment time and post-operative acceptability were also evaluated for both the groups.

Results: The cumulative survival rate of IRC onlays was 82.9% compared to 90.7% for SSCs over a time period of 36 months. The difference between the two study groups at various time intervals in terms of retention, marginal integrity, secondary caries, proximal contact, occlusion and gingival health was not statistically significant (p>0.05). The IRC onlays required significantly less mean chair side treatment time and were preferred the most by parents and children as per VAS scores compared to SSCs.

Conclusion: IRC onlays are an acceptable esthetic alternative to SSCs and may be considered for use in aesthetically conscious children/parents as per their preference.
