Comparative Analysis of Bilayered and Direct Restorations in Class V Lesions: A Retrospective Study

Author(s): Swathi UB, Sindhu Ramesh* and Delphine Priscilla Antony S


Composite Resins are the most commonly used tooth colored restorative materials. However, these materials undergo contraction during curing and result in shrinkage of the material. The usage of glass ionomer cement and composite is called the “Sandwich restoration” and has been proposed to improve marginal adaptation of composite resin and bonding agents. The purpose of this study was to evaluate the usage of bilayered and direct composite restorations in class V lesions. This retrospective study was based on patient records collected from Saveetha Dental College, Chennai. Data collected consisted of 1721 cases in which the type of restoration used for restoration of Class V lesions over a period of one year was evaluated based on the patient's age, gender, tooth in which the restoration was done. In this retrospective study it was observed that there was a significant difference between the type of restoration selected for restoration of Class V lesions (P value >0.5).Direct restorations of Class V lesions was preferred in majority of the cases (87%) followed by usage of bilayered restorations in 13% of overall cases. Based on the results on this study, direct restorations are the most preferred technique for restoration of Class V lesions. Bilayered restorations were used in a minimal number of cases in this retrospective study. Bilayered technique could be advantageous when compared to composite or glass ionomer cement restorations are used alone, especially when gingival margins are examined.
