Clinicalexaminations were conducted by seating the crown on the tooth preparation and visual assessment was done usingsharp explorer along the margins. Clinically acceptable crowns were then evaluated on the bite-wing radiograph.Any horizontal or vertical inaccuracy of >0.5mm at the proximal margins was recorded as 'discrepancy'. Data wasanalysed using SPSS 22.Results: Of the 230 interproximal margins of 115 crowns evaluated, 113(49.1%) sites had marginal discrepancies;44(19.1%) horizontal discrepancies, 58(25.2%) vertical discrepancies, and 11(4.8%) having both horizontal andvertical discrepancies. Horizontal crown margin discrepancies were most associated with the mesial site of themaxillary crowns, while vertical discrepancies were commonly associated with the distal aspect of all crowns(p<0.050).Conclusions: Almost half of the crowns that were considered clinically acceptable had some vertical or horizontalmarginal discrepancy on radiographic evaluation.
