ESSENTIAL PERIODONTICS

The Dentistry Essentials are an international series of textbooks, designed to support lecture series or themes on core topics within dentistry.

A comprehensive yet accessible reference text designed for dental students and healthcare professionals alike

Essential Periodontics provides rapid reference to key information about periodontal pathology, examination and diagnosis, treatment planning of common diseases, dental implantology, clinical decision making, and more.

Contributions from experienced practitioners cover all the fundamental topics encountered in both periodontic training and practice, such as the anatomy and histology of the periodontium, basic principles of periodontal health, surgical therapies and suturing techniques, interdisciplinary periodontics, and management of periodontal emergencies. Each easy-to-read chapter includes a concise introduction, clearly defined learning objectives, a reference list of relevant scientific publications, tables and figures, and high-quality illustrations and clinical images.

  • Aligns with the Classification of Periodontal and Peri-Implant Diseases and Conditions issued by the American Academy of Periodontology (AAP) 2018 World Workshop
  • Follows a flexible modular format which can be easily integrated into any dental school’s teaching curriculum
  • Discusses future advances and research in periodontics
  • Includes several useful appendices, references to internet resources, and an extensive index

Reflecting current practice and up-to-date scientific evidence, Essential Periodontics is a valuable resource for undergraduate dental students and healthcare professionals including dental hygienists, dental therapists, and general dentistry practitioners, which also includes interdisciplinary interests.

Foreword

I am proud to write the Foreword to Essential Periodontics. Our knowledge about the periodontium and its diseases is continuously increasing. Advanced research in genomics, proteomics, and metabolomics is also being applied in the field of Periodontology, giving us a new understanding of the pathogenesis of periodontitis. High-throughput sequencing techniques have led to a new view on the oral microflora. The number of newly identified microbial species in the oral cavity is increasing on a yearly basis.

Periodontology is a very active research field. More than 2000 new articles in the field of Periodontology are added to PubMed each year. Over 15 000 articles have been published since the beginning of 2015. This new textbook incorporates as many new insights and future trends as possible and the new classification system, introduced in 2018, is used throughout the book.
