One of the major shortcomings of the restorative materials, was the lack of adhesion to the tooth structure (2 -5). The restorative material that does not bond to tooth structures are more suscaetible to allow oral fluids and debris to penetrate at the tooth-restoration interface. This might lead to recurrent caries and/or failure of restorations (6,7). Attempts were done to minimize marginal leakage by using cavity liners or varnishes (1,8). Their ability to reduce leakage, penetration of bacteria and soluble ions into the underlying dentin has been demonstrated. However, because of their inferior physical and chemical properties in comparison with the conventional restorative resins, these amterials do not provide a satisfactory solution to the problem of marginal leakage (9). Although the composite restorative resins in conjunction with the acid etching technique have been used successfully for manv years in clinical practice (10,11). The acid etching technique has shown the greatest potential in reducing marginal leakage (12-15). Thus, the objective of this study, was to evaluate the occurrence of secondary caries like lesions in relation to conventional and microfilled composite resin restorations  ISSN : 0  Journal Name : Egyptian dental journal  Volume : 34  Issue Number : 4  Publishing Year : 1988 AH 1988 AD  Article Type : Article  Added Date : Monday, December 10, 2007  Researchers Researcher Name (Arabic) Researcher Name (English) Researcher Type Dr Grade Email عصام نجيب Najeeb, esam Investigator Doctorate enajeeb@kau.edu.sa Files File Name Type Description  INCIDENCE OF CARIOUS LESIONS AROUND.pdf pdf   Back To Researches Page
