ABSTRACT
Objective: To Evaluate Class V Cavities Restored By Different Bioactive Restorative Materials.

Materials and Methods: Sixteen Patients Were Selected According To The Inclusion-exclusion Criteria With Three Carious Cervical Lesions In Each Patient. A Total 48 Class V Cavities Were Prepared According To Caries Extension And Randomly Restored With: Group I (Activa? Bioactive Composite), Group II (BeautifilII) And Group III (Fuji IX GP EXTRA) Which Were Applied Following Manufacturers? Directions. Each Restoration Was Clinically Evaluated At 24 Hours, 6 Months And 1year Using ModifiedUSPHS Criteria. In Addition, Marginal Seal Of The Tested Restorations Was Further Examined Under Scanning Electron Microscope Using Epoxy Resin Replicas.

Results: Using Chi-square Test, There Was No Statistical Significantdifferences Between The Tested Groups For Retention, Marginal Adaptation, Marginal Discoloration, Anatomical Form, Surface Texture And Color Matching (p>.05). None Of The Restorations Had Secondary Caries At Any Evaluation Period. Post-operative Hypersensitivity Was Found In Group I At The Base Line In 18.8 % Of Cases, While There Was A Statistical Significantdifference Between The Different Evaluation Periods (p = 0.045) & Among The Tested Groups At The Base Line (p = 0.041). SEM Examination Of Replica Revealed No Statistically Significantdifference Neither Between The Three Groups In Any Evaluation Period Nor Between Different Evaluation Periods In Group I And II (p Value = 0.468 & 0.269) Respectively. However, A Statistical Significantdifference Was Recorded Between The Three Follow Up Periods In Group III (p= 0.048). Spearman?s Correlation Test At A Significantlevel Of P ? 0.05) Was Performed Between The Related Tested Criteria In Each Group And Recorded A Positive Relationship After 6 And 12 Months Follow Up Periods.

Conclusions: The Three Different Bioactive Restorative Materials Showed An Acceptable Clinical Performance In Class V Cavities By The End Of The Examination Period.
