The third edition of Essential Endodontology: Prevention and Treatment of Apical Periodontitis has been revised and updated to include the most recent developments in the field, maintaining its position as the major scientific treatise of apical periodontitis. Making an often-complex subject more digestible, the book explores the scientific basis of endodontology, adopting a systematic analysis of the available clinical and laboratory evidence.
Promoting apical periodontitis as a disease entity, the comprehensive third edition focuses on its biology and clinical features, enabling the reader to have a better understanding of its diagnosis, prevention and treatment. In addition to thorough updates and full colour illustrations throughout, a new chapter on regenerative endodontics has been added to this edition.
This is the second edition of this successful textbook which is known within the field as a 'scientific treatise' on apical periodontitis. It is written by Dag Orstavik, a Professor of Endodontology at the University of Oslo and Tom Ford, a Professor of Endodontology at the GKT Dental Institute in London. They are both world renowned authors and from the tone of the book they are heavily involved with research in this field.
The book is based on a scientific background and research as you would expect from the title, and it clearly puts across the point that apical periodontitis is a disease entity and is the disease of reference in endodontics. Early chapter focus is purely on apical periodontitis and covers the various aspects such as epidemiology, histology, microbiology, radiology and anatomy. These early chapters would make an excellent addition to the armamentarium of books an early dental undergraduate may use. Although these topics can often be quite dry they are presented in a fresh and lively manner here with plenty of colour pictures, tables, slides and diagrams. These help to enrich the text and with the subheadings provide an easy to read layout.
Once the initial topic of apical periodontitis is covered the book moves into more clinical matters such as prevention, treatment, surgery and healing. Particularly useful features for the undergraduate are the areas on diagnosis which includes typical clinical symptoms and differential diagnoses. Chapters involving treatment have plenty of useful photos that clearly demonstrate the points being made. The book excels in particular in later chapters by providing treatment options for example different choices of irrigants and filling materials. It then explains the rationale for the use of the various types and provided evidence showing what should be used, when and why. It can sometimes feel a little vague or rushed in places, for example only having one paragraph covering mineral trioxide aggregate (MTA) as a retrograde root end filling material. A lot more research and data on this new and increasingly used material might have been expected.
Data on the prevalence and quality of root canal fillings are rare in Morocco. Considering the fact that these data are important for the evaluation of the quality of the endodontic treatment realized as well as for dental care planning and the need of such information, the aim of this study was to investigate the prevalence and quality of root canal fillings and their association with periapical periodontitis in a group of patients from Morocco.
A total of 508 panoramic and 709 periapical radiographs were examined. The periapical radiographs were systematically performed whenever a panoramic X-ray showed a tooth, a coronary, or radicular obturation with suspicion of a periapical lesion. The records of patients, whose radiographic examinations could not be made, regardless of the cause, were excluded from the study. Although panoramic radiographs provide a general overview of dentomaxilomandibular structures, periapical radiographs had higher definition and yielded more information on the status of the periapical bone , so periapical radiographs were used in this study mainly to evaluate the degrees of apical periodontitis and the quality of the endodontic treatments.
High frequency of AP in teeth with inadequate root canal fillings has been reported in several previous studies [27, 36, 42, 43]. In this study, inadequate treatments were associated with a significantly high prevalence of periodontitis; 91.5% of inadequate endodontic treatments had apical periodontitis and only 8.5% of the appropriate treatments presented AP.
The frequency of AP in endodontically treated teeth of this patient group was high, especially in teeth with inadequate root fillings, demonstrating that the quality of endodontic treatment is a factor associated with the appearance of apical periodontitis.
This cross-sectional study aimed to investigate the prevalence of apical periodontitis (AP) and root-filled teeth in a 65-year-old population in Oslo, Norway, and to investigate associations of pathosis and endodontic treatment with selected individual risk indicators and technical quality of root fillings.
Apical periodontitis (AP) is inflammation and destruction of periapical tissues caused by endodontic infection [4, 5]. The infection is treated by root canal disinfection and subsequent root-filling, endodontic microsurgery or tooth extraction . Researchers have pointed out that in the elderly, endodontic treatment may become more difficult to perform due to potentially previous treatment traumas and age changes to the pulp . The fact that aging is correlated with reduced general health can also impose challenges for endodontic treatment, as elderly, fragile patients may find prolonged dental visits exhausting. 2b1af7f3a8
