Bulk fill vs incremental layering in posterior restorations: Systematic review

Effect of Multilayering Incremental Technique on the Microleakage of High-viscosity Bulk-fill Composite Restorations in Endodontically Treated Teeth

“…The similar results with bulk-fill composites were published by Yongwen et al, 9 Siavash et al, 13 Shrivastav et al, 11 Scotti et al, 12 Peutzfeldt et al, 15 and Mirosław et al 14 The most significant finding was that the bulk-fill composites when incrementally filled displayed the best results with minimal shrinkage combining the benefits of both the improved chemistry and the incremental technique. No other research compliments or support our results as there is no other study like this conducted till now but there is a plethora of studies which support the benefits of incremental techniques: Loguercio et al, 25 Al-Harbi et al, 26 Tiba et al, 27 Moezyzadeh and Kazemipoor, 28 Jang et al, 29 and Reis et al 30 This study clearly supports a new multilayering incremental placement approach for the use of bulk-fill composites in deeper access preparations without compromising the marginal integrity. There is not much research to support this study as it is a relatively novel concept and more clinical studies are needed to further validate this research.…”
