PREFACESince the person attains supreme formBy doing duty in a spirit of sacrifice.Thus do your duty without attachmentPerform the work that has to be done, (The Bhagvatgita: Ch III, Verse 19)I am pleased to present to users the Edition of CURRENT DIAGNOSTIC TOOLS OF PERIODONTAL DISEASES for Dental students with thoroughly updated contents. The book attempts to incorporate most recent advances of diagnostic tools to diagnose the periodontal diseases in Periodontics while at the same time not losing the sight of basics. The availability of diagnostic tools in dentistry today is vast. However, during both our graduation as well as postgraduation, we always felt the need for a book which would help us to revise and update our knowledge. Emphasis is laid upon the language which is simple, understanding and exclusively designed for undergraduates, postgraduates, practitioners and teachers in the field.
