The 'Marginal integrity of Restoration' refers to its marginal fit and marginal breakdown thereby increasing the longitivity of restorative materials. The marginal deterioration refers to poor marginal adaptation,which may produce marginal discoloration,post operative sensitivity and secondary caries. The accurate evaluations evaluation of marginal qualities are important for identification of future failures of dental restorations. Despite the improvement in many restorative materials marginal integrity of restorations still remain a challenge in dentistry. This book tries to give a comprehensive knowledge about factors affecting marginal integrity of dental restorations and different techniques of improving the marginal adaptations. It focuses on history.,factors affecting marginal adaptation of restorations,methods of improving marginal adaptation,clinical implications of microleakage and various methods of detecting microleakage and Recent advances in dental restorations, with wide range of reviews. A list of references is also provided to encourage further readings. A deep understanding and love for the subject has been given into making of this book.
