Relationship Between Operator Experience And In Vitro Microleakage of Different Composite Materials in Class II Restorations

Objectives: To evaluate the influence of operator experience on microleakage in class II restorations performing by different restorative materials. Material and Method: 2 cavities 4x4x3mm dimensions were carried out mesial distal surfaces 20 molar teeth one operator. The randomly assigned to two groups according operator’s skill: student group expert group. It was divided into subgroups as specialist bulk-fill composite: Group 1A, 2A, micro-hybrid 1B, 2B, Prime bond nt, a total-etch adhesive system, is used all restorations. Each restored with bulk technique using composite (Tetric-N-Ceram-Bulk) layering (Filtek Z250, 3M ESPE). After 24 hour water storage thermocycling marginal microleage evaluted dye penetration data analyzed. Results: When materials evaluated without considering applying operator, when scores who applied used, no statistically significant difference found between them (p>0.05).When occlusal gingival leakage 2A evaluated, more observed than (p<0.05). There in-group leak other (p>0,05). Conclusion: terms values.
