“…Our findings regarding Group A echo with Sarfi et al findings, where no statistically significant difference was found in microleakage between two incremental techniques (Sarfi et al, 2017 ) but are different from the findings of Tjan et al where the bulk technique showed more leakage than the incremental techniques (Tjan et al, 1992 ). Our findings show that bulk composites have evolved over the years and can now provide similar marginal integrity to other types of composite materials.…”

Objectives Microleakage in direct dental restorations is a primary causal factor in the restoration's failure. The aim of this study was to evaluate whether the technique for occlusal layering of the composite resin (the use of brush adaptation, the use of magnification, cusp build‐up, stamp technique) has any effect on microleakage of direct restorations in occlusal cavities. Materials and Methods One hundred extracted human molars were restored using five restoration techniques (Packable Bulk technique, Occlusal Stamp technique, Successive Cusp Build‐up technique, Successive Cusp Build‐up technique + Brush adaptation, Successive Cusp Build‐up technique + brush adaptation + Dental Operative Microscope magnification). The teeth were subjected to thermal aging for 800 cycles at 5°C and 55°C, infiltrated with basic fuchsin dye for 24 h, and then sectioned buccolingually in the middle of the crown. Infiltration was measured in four areas of the tooth section by five different observers and then given a score from 1 to 3, proportional to infiltration depth. Results The lowest mean scores for infiltration (meaning less infiltration observed) were present in Group A (1.41 ± 0.878) and Group C (1.46 ± 0.679), while Group D showed the highest infiltration scores (1.75 ± 0.853). When comparing the groups for differences, no statistically significant difference in infiltration was found between any technique p < .586. Conclusion The techniques examined for placing the occlusal layer of composite in direct restorations do not differ significantly in terms of marginal infiltration, although a slight improvement was found when using the bulk technique and the successive cusp build‐up.

“…Composite resin materials, therefore, have been developed in different filler sizes from macro to micro, then hybrids, and finally the nano-fillers. [1][2][3][4][5][6] Despite this advancement, there is still no improvement in the marginal adaptation observed with the addition of filler particles, particularly with light-cured resins. 7 Two composite resins are commonly used to formulate dental composite matrices: Bis-GMA (bisphenol A-glycidyl methacrylate) and urethane dimethacrylate (UDMA).…”

The study aimed to introduce a perspective of the essential reason behind why marginal microleakage develops regardless of the composite type, the technique, or the bonding system applied, especially in gingival floor of class II cavities. Materials and Methods: Three types of composite resin materials (CharmfilTM, ParaFillTM, and ProMedica®) were used to evaluate microleakage of class II restorations using two restorative approaches. Twenty four newly extracted bicuspid teeth were divided into two main groups (n=12 each) according to the restoration technique (open or closed sandwich techniques). Teeth of each group were then divided into 3 groups (n= 4 each) according to the type of the composite resin used. The restorations were then subjected to a thermocycling process and then were immersed into methylene blue solution for 12 hours. Mesiodistal sectional cuts were made along the central grooves and assessed under stereomicroscope for marginal microleakage. The data were statistically analyzed with a p-value <0.05 considered significant. Results: There were no statistically significant differences in marginal microleakage between the three examined groups using both techniques (p>0.05). Under the microscope, the marginal microleakage was more obvious at the cervical region than at the occlusal region. Conclusion: There was no effect of the composite type or the application technique used on the occurrence of marginal microleakage. The first portion of the material applied against the cavity floor is the primary factor involved in possibly minimizing marginal microleakage.
