Definition: The word "periodontol" may refer to a medical condition or disorder that affects the oral and periodontal tissues, including bone and tissue that surrounds teeth and the gums. It is also known as gingivitis or periapical infection. Periodontal disease refers to an inflammation of the gums and bone around tooth roots and the jawbone. This condition can be caused by plaque buildup on the gum and supporting structures, which can lead to sensitivity, tooth decay, periodontal ligament damage, bone loss, and gingivitis (an inflammatory reaction to gingival tissue). The word "periapical infection" refers to inflammation of a tooth root or jawbone. This condition is often associated with periodontal disease but can also be caused by dental caries or trauma. In summary, the term "periodontol" could refer to an oral health problem involving the gums and bone structures surrounding teeth and the jawbone, while periapical infection refers to inflammation of a tooth root or jawbone. Both conditions can affect the health of your teeth and gum tissue.
