    Abstract in Arabic Abstract in English

    The aims of this study were to evaluate the microleakage in the Class II Cavities Restored with methacrylate resin composite (Tetric Ceram HB) or silorane resin composite (P90 Filtek) that had been stored in different situations and temperatures. Materials and Methods: thirty six intact human upper first premolars were employed. Two Class II cavities with specific dimensions had prepared on each tooth mesially and distally. Teeth were Restored by Methacrylate Resin (HB IVOCLAR), Silorane Resin (P90), Under three different conditions: Group (A): application of composite and Adhesive System at room temperature (24°C), Group (B): application of composite and Adhesive System, immediately after removal from refrigerator temperature (4°C), Group (C): application of composite and Adhesive System, 30 minutes after removal from the refrigerator at room temperature (24°C).Results: This study observed a statistically significant increase in microleakage when applying each of methacrylate composite (HB IVOCLAR) and silorane composite (P90) immediately after removal from refrigerator temperature (4°C) Compared when applied at room temperature (24°C) and when applied 30 minutes after removing from refrigerator temperature, no significant differences were found between silorane composite (P90) and Methacrylate composite (Tetric HB) in microleakage when comparing the two types of resin in the three ways used in storing both resins.

    Effect of Multiple usage and surface coarseness of diamond burs on Marginal Microleakage of Resin Composite Restorations (An In- vitro study)
    836 - Tishreen University 2016 ورقة بحثية
    Aim: to compare the effect of multiple usage and surface coarseness of diamond burs on marginal microleakage of cervical resin composite restorations. Materials and methods: sixty extracted premolars without caries were chosen. The sample was rand omly divided into three groups: n1=n2=n3=20. Group(1): class v cavities were prepared using super coarse diamond burs, group(2): prepared by coarse diamond burs, whereas group)3(: prepared by medium coarse diamond burs. All cavities were restored by resin composite, then The teeth were thermocycled and immersedIn5%solution of methylene blue dye for 12hours.Then the teeth were sectioned vertically, Dye penetration was evaluated using a 10X stereomicroscope at the occlusal and gingival margins. Data were collected and statistical analysis was conducted. Results: The results showed that the multiple use of super coarse diamond burs caused no significantly statistically affect on occlusal and gingival microleakage (P>0.05). However, the multiple use of coarse and medium diamond burs caused significantly statistically affect on gingival marginal microleakage (P<0.05).

    The aim of this in vitro study was to evaluate the microleakage on the gingival margin located below the cemento-enamel junction of class II composite restorations (CR ,Tetric-ceram,Vivadent) applied with a 5th generation bonding material (Excite,Vivadent) and to compare it with that seen in open sandwich restorations using a nanoionomer material (OST ,Ketac N100,3M) and a composite material (Tetric-ceram).

    Clinical Comparative study between modified metal matrix and gingival retraction cords for microleakage in class V restorations
    1561 - Tishreen University 2016 ورقة بحثية
    This study aims to in vivo evaluate the direct microleakage, in class V composite restoration after isolation using the modified metal matrix or gingival retraction cord impregnated with Adrenaline. Materials and Methods: the research sample consiste d of 15 patients; each patient has two premolars at least prepared to be extracted for Orthodontic reasons in the same jaw. This sample divided into two groups according to the place, the right premolars group and the left premolars group, whether was upper or lower. Class V cavity was prepared with a specific dimensions on the buccal surface only, then isolated teeth of the first set by modified metal matrix while isolated teeth of the second set by a gingival retraction cord impregnated with Adrenaline. Teeth restored by composite resin, and then was extracted in the same meeting and studied the microleakage winning directly during restoration. .Results: there was statistical difference between the modified metal matrix and the gingival retraction cord impregnated with Adrenaline. Because modified metal matrix had achieved the lowest leakage rate.
