Viral infections of the oral cavity usually manifest as either ulceration or blistering presentation of oral tissues. Oral viral infections are encountered in dental practice but received less clinical interest due to the lesser frequency of patients and diagnostic challenges. The clinical presentation, pathogenic mechanism, investigations, and management of oral viral infections are integrated into the book which will enable general dentists to develop critical thinking processes on differential diagnosis and management through a multidisciplinary approach with specialist dentists.

The central nervous system (C.N.S) and oral cavity have a close anatomical location. They have common vascular supply and a related embryological origin. Motor and sensory organs in orofacial area have numerous connections with C.N.S. via the cranial nerves. As yet, diseases of C.N.S. have been studied in different branches of medicine such as otology, ophthalmology, neurology, neurosurgery and dentistry. Recognition of orofacial manifestations of C.N.S. disorders are in direct relation with the responsibilities of a dentist. Classification and defining of a unique methodology for recognition...
