Understand the etiology and pathogenesis of periodontal disease, unraveling the role of risk factors such as plaque, calculus, smoking, and systemic diseases.
This edition also emphasizes the clinical manifestations of periodontal disease, equipping readers with the ability to recognize and diagnose various stages of periodontal disease.
Introduction to Periodontics
Periodontics is the specialty of dentistry that focuses on the prevention, diagnosis, and treatment of diseases of the periodontium, the tissues that support the teeth. The periodontium includes the gingiva (gums), periodontal ligament, cementum, and alveolar bone.
Periodontics has a long and rich history, dating back to the early days of dentistry. In the 19th century, periodontitis was recognized as a distinct disease entity, and in the 20th century, the development of new surgical techniques and antibiotics revolutionized the treatment of periodontal disease.
Periodontics is an important part of dental hygiene. Dental hygienists play a vital role in the prevention and treatment of periodontal disease by providing preventive care, such as scaling and root planing, and by educating patients about the importance of good oral hygiene.
Anatomy and Physiology of the Periodontium
Anatomy of the Periodontium
The periodontium is composed of four main tissues:
- Gingiva (gums)
- Periodontal ligament
- Cementum
- Alveolar bone
The gingiva is the soft tissue that covers the alveolar bone and surrounds the teeth. The periodontal ligament is a thin layer of connective tissue that connects the tooth to the alveolar bone. Cementum is a mineralized tissue that covers the root of the tooth.
Alveolar bone is the bone that forms the sockets in which the teeth are embedded.
Physiology of the Periodontium
The periodontium performs a number of important functions, including:
- Supporting the teeth
- Protecting the teeth from damage
- Providing nutrition to the teeth
- Sensing changes in the oral environment
The periodontium is also closely linked to the immune system. The gingiva contains a number of immune cells that help to protect the periodontium from infection.
Etiology and Pathogenesis of Periodontal Disease
Major Risk Factors for Periodontal Disease, Foundations of periodontics for the dental hygienist 6th edition
The major risk factors for periodontal disease include:
- Plaque
- Calculus
- Smoking
- Systemic diseases (e.g., diabetes, HIV)
Plaque is a sticky film of bacteria that forms on the teeth. Calculus is a hard, calcified deposit that forms on the teeth and can irritate the gums. Smoking damages the immune system and makes it more difficult for the body to fight off periodontal infection.
Systemic diseases can also increase the risk of periodontal disease by weakening the immune system.
Pathogenesis of Periodontal Disease
Periodontal disease is a chronic inflammatory disease that is caused by bacteria in the plaque. The bacteria produce toxins that damage the periodontal tissues and trigger an inflammatory response. The inflammatory response leads to the destruction of the periodontal tissues, which can eventually lead to tooth loss.
Periodontal disease progresses through a series of stages, from gingivitis to advanced periodontitis.
- Gingivitis is the early stage of periodontal disease. It is characterized by inflammation of the gingiva, which can cause bleeding, swelling, and redness.
- Periodontitis is a more advanced stage of periodontal disease. It is characterized by the destruction of the periodontal tissues, which can lead to tooth loss.
Clinical Manifestations of Periodontal Disease
Clinical Signs and Symptoms of Periodontal Disease
The clinical signs and symptoms of periodontal disease can vary depending on the stage of the disease. However, some of the most common signs and symptoms include:
- Bleeding gums
- Swelling and redness of the gums
- Gum recession
- Loose teeth
- Pus between the teeth and gums
- Bad breath
- Pain when chewing
Diagnosis of Periodontal Disease
Periodontal disease is diagnosed based on the clinical signs and symptoms of the disease, as well as the results of periodontal probing and radiographs.
Periodontal probing is a procedure in which a dentist or hygienist uses a thin probe to measure the depth of the periodontal pockets. The depth of the periodontal pockets can indicate the severity of the periodontal disease.
Radiographs can also be used to diagnose periodontal disease. Radiographs can show the extent of bone loss that has occurred as a result of periodontal disease.
Differential Diagnosis of Periodontal Disease
Periodontal disease can be confused with other oral conditions, such as gingivitis, mucositis, and periodontitis. It is important to differentiate between these conditions in order to provide the appropriate treatment.
Gingivitis is a reversible inflammation of the gingiva. Mucositis is a reversible inflammation of the mucous membranes of the mouth. Periodontitis is a chronic inflammatory disease that affects the periodontal tissues.
