Oral cavity is a complex system which is subjected to variety of microorganisms and local irritants factors which may disrupts the homeostasis and lead to variety of diseases, thus it necessitates to formulate drugs which is effective to withstand the oral environment. Specialized drug delivery systems are developed to overcome these difficulties and thus provide effective drug dosage. This book provides the readers a glimpse about the basic understanding about the oral epithelium, mechanism of drug penetration, factors which affect the drug absorption ,deals with the various drug...

Recent advances in opg is a compilation of the latest trends in the field of orthopantogram .it gives an insight of panorama "an unobstructed view of a region in every direction "at present scar. A technology (selectively compliant articulated robor arm) in panoramic radiography where no mechanical constraints for the imaging geometry is required and image layer is fully formed by software. Promax x- ray's unique software-driven robotic arm creates more imaging program possibilities than other panoramic x-rays. In fact, the promax digital panoramic offers more than 30 different imaging...
