The bone destruction patterns that occur as a result of periodontal disease generally take on characteristic forms. This X-ray film displays a horizontal defect . This X-ray film displays two lone-standing mandibular teeth, #21 and #22: the lower left first premolar and canine, exhibiting severe bone loss of 30-50%.
Wisdom teeth are not included because pericoronitis and tooth impaction may cause isolated periodontal defects which do not represent the general periodontal condition of the rest of the mouth. At least 2 teeth must be present in a sextant for it to be scored. If only 1 tooth is present in a sextant, the tooth is included in the adjoining sextant.
Periodontal disease, also known as gum disease, is a set of inflammatory conditions affecting the tissues surrounding the teeth. [5] In its early stage, called gingivitis, the gums become swollen and red and may bleed. [5] It is considered the main cause of tooth loss for adults worldwide.
Periapical COD occurs most commonly in the mandibular anterior teeth while focal COD appears predominantly in the mandibular posterior teeth. Florid COD is an extensive variant of periapical COD where lesions occur in multiple quadrants which can encompass the maxilla and mandible, and infrequently can cause jawbone deformity.
The most common causes for odontogenic infection to be established are dental caries, deep fillings, failed root canal treatments, periodontal disease, and pericoronitis. [2] Odontogenic infection starts as localised infection and may remain localised to the region where it started, or spread into adjacent or distant areas.
Idiopathic osteosclerosis, also known as enostosis or dense bone island, is a condition which may be found around the roots of a tooth, usually a premolar or molar. [2] It is usually painless and found during routine radiographs as an amorphous radiopaque (light) area around a tooth.
To complete the diagnosis, the extent of the disease must be assessed. This is defined as: mild (1-2mm), moderate (3-4mm) or severe (≥ 5mm) depending on the amount of attachment loss present. Radiographs such as bitewings, intra-oral periapicals or a panoramic radiograph can be taken to help assess the bone loss and aid in diagnosis.
These terms can also be used to refer to the clinical sense of the words, as relative crown and relative root, by describing how much tooth remains surrounded by bone.As the inflammation associated with periodontal disease causes the bone to resorb and disappear, revealing more of the root structure, the effective crown height in relation to the effective root height is reduced and the ...
