This book was written to demonstrate step-by-step the technique of instrumentation and how to remove the deposits by supragingival and/or subgingival instrumentation. The current book (Periodontal Instruments and Instrumentations) is a conclusive proof of many research findings to present this information in a concise, easily referenced format and to encourage newly qualified practitioners in a general practice setting, to maintain and further develop skills in treatment of periodontal conditions. It is our hope that this new book will be useful to dentists, periodontists, and dental students. This book is dedicated to our families, friends and lecturers. .
