ABSTRACT


Purpose: To Evaluate The Clinical Performance Of Bulk Fill Composite In Open Sandwich Technique Using Either Flowable Composite Or Resin Modified Glass Ionomer Liners After One Year.

Materials & Methods: A Total Of 20 Patients (4 Males & 16 Females Aged 25- 45 Years) Participated In This Study. Sixty Class V Cavities Were Restored With Either Tetric N Ceram Bulk Fill Composite Only, Tetric N Ceram Bulk Fill Composite With Flowable Composite Liner (Tetric N Flow) Or Tetric N Ceram Bulk Fill Composite With Glass Ionomer Liner (Ionoseal) Representing Three Main Groups (n=20). Each Patient Received At Least Three Restorations. The Cavity Design Was Restricted To Eliminate Carious Tissues From Primary Carious Lesions. All Restorations Were Subjected To Clinical Follow Up Schedule Representing (base Line, 6 Months And 12 Months) By Two Investigators. The Restorations Were Evaluated According To The Modified USPHS Criteria. The Data Were Collected, Tabulated And Statistically Analyzed At A Level Of Significance (P ? 0.05) Using Chi Square Test.

Results: Regarding The Clinical Performance Of The Tested Materials, There Was No Statistically Significant Difference Among The Three Tested Groups At Different Follow Up Periods (P > 0.05). Spearman?s Test Revealed A Statistical Positive Correlation Between Marginal Adaptation Versus Both Marginal Discoloration And Anatomic Form As Well As Marginal Discoloration Versus Both Surface Texture And Color Match.

Conclusions: 1- Bulk Fill Composite Restorations Placed In Sandwich Technique Exhibited A Satisfactory Clinical Performance After 1 Year Clinical Service Compared To Those Placed Without A Liner. 2- Flowable Composite Liners Had Better Clinical Behavior Compared To Resin Modified Glass Ionomer Liner.
