BACKGROUND This study aimed to evaluate the microleakage, when flowable composite is used as a restorative material and a liner. MATERIALS AND METHODS Forty, non-carious, extracted human premolar teeth were used and they were divided into five groups according to the type of composite material used. Group I: Hybrid composite was inserted and cured for 40 s. Group II: Flowable resin composite ...

An important product of the software design phase is the speciication of the software structure at various levels of detail. Without reliable design documentation, signiicant software systems become less accessible to software engineers because structural information is buried in the intricate implementation source code. Reverse engineering techniques aim at recovering the structure of software...

rheumatoid arthritis is a chronic multi-system disease of unknown cause. it affects the people in their prime of life, predominantly between the ages of 20-50 years with unpredictable course. sudard is used in the ayurvedic system of medicine for the treatment of inflammation and pain associated with rheumatoid arthritis, osteo-arthritis, frozen shoulder, sciatica, ankylosing spondylitis and ch...

background: microleakage is still one of the defects of resin composites that can lead to treatment failure; and re-bonding technique is one of the effective ways to reduce it. this study evaluated the effect of re-bonding with a surface sealant or a dentin adhesive on microleakage in class v microhybrid, nanohybrid, and packable composite restorations. materials and methods: in this in vitro s...
