Study Notes

Radiographic Examination in Periodontics

Radiographs provide information on periodontal ligament space, alveolar bone condition, root length, and morphology
Factors initiating periodontal disease include poorly-contoured restorations, malpositioned teeth, open contact points, and dental anomalies
Radiographs show anatomic considerations, caries, periapical lesions, root resorption, but not soft tissue to hard tissue relationships
They may not detect incipient bone lesions, and only show a two-dimensional view of a three-dimensional situation
Radiographic detection of periodontal disease should follow careful clinical examination and meet specific criteria for quality
Intraoral radiographs are examined horizontally and separately for each pathology, using bite-wing and periapical views
The parallel technique is preferred for periodontal examination to minimize superimposition of structures
Panoramic views are not suitable for detecting incipient alveolar crest lesions due to decreased resolution and overlapping
Normal periodontium in radiographs shows thin, smooth, pointed alveolar crests in the anterior region
In the posterior region, alveolar crests are relatively thick, smooth, and flat to rounded
Chronic periodontal disease forms slowly with horizontal bone loss and thick crest margins, while acute disease advances rapidly with vertical/angular bone loss and irregular crest margins
Angular bone loss is the first sign of periodontal disease

Periodontal Disease and Radiographic Interpretation

Chronic periodontitis occurs due to neglect of oral hygiene, leading to calcification and calculus formation
Most common area for calcification is the molars due to saliva access, seen as triangular radio-opaque areas on x-rays
Acute irregular bone loss is caused by irritating factors like overhangs, leading to irregular bone quality
Small regions of bone loss on buccal or lingual aspects of teeth are difficult to detect clinically, but can be identified on radiographs
Initial periodontal disease is seen as a loss of cortical density and a rounding of the junction between alveolar crest and lamina dura
The condition is not periodontitis, but rather alveolar bone loss if there is no teeth present
Gingivitis, inflammation with no bone loss, does not show radiographic evidence of bone loss
Radiographs may not show depth of soft tissue pockets, and features not well detected by radiographs are apparent clinically
Horizontal bone loss can be mild, moderate, or severe, with different implications on attachment loss and furcation areas
Widening of the periodontal ligament space at the apex indicates furcation involvement and potential endo-perio lesions
Radiographs do not always provide a complete picture, and clinical examination should always be correlated with radiographic findings
Systemic diseases like diabetes mellitus and Langerhans cell histiocytosis can have effects on the periodontium, which should be checked in the medical history
