Radiographs in periodonties

Abstract

Intraoral radiographs are widely used in periodontal diagnosis and research. However, accurate radiographic interpretation is only possible with high quality images. Some of the technical and geometric variables to consider have been presented. Early periodontal lesions are not detected in radiographs. The amount of periodontal destruction in more advanced disease is generally underestimated. The accurate topography of periodontal pockets and the buccal and lingual aspects of the teeth cannot be visualized. Clinical probing is therefore a prerequisite for a complete periodontal diagnosis. However, radiographs are a valuable adjunct for the periodontal diagnosis and the diagnosis of trauma from occlusion. With standardized systems, radiographs may furnish additional quantitative data in clinical research.

Osteoblast Apoptosis in Periodontal Disease: Role of TNF-Related Apoptosis-Inducing Ligand

“…In particular, the Pp included in the study showed: PI and GI from 2 to 3 (31), probing pocket depth 6.1±2.5 mm (range 4-10 mm), probing attachment level 6.7±1.4 mm (range 5-11 mm), and alveolar bone loss 40.5±16% (range 20-85%). Alveolar bone loss determination was performed using radiographic and clinical evidence concerning the distance between the cement-enamel junction (CEl) and the level in which periodontal ligament appeared normal (32)(33). In the controls PI and GI were 0, no evident signs of attachment loss were detected.…”

Dentascan – Is the Investment Worth the Hype ???

“…In this study, Kodak imaging software, 6.8. 6.0 was used to analyze the amount of ABL. Daniel M et al, showed that digital radiography was less diagnostically accurate as compared to conventional radiography.…”

“…In routine dental practice, 10-14 IOPAs (Intra-oral periapical radiographs) and panoramic radiographs (OPG) are the most established imaging techniques [6,7]. However they tend to underestimate the bone loss and they also often tend to obscure defects, dehiscences, etc., especially when they are placed behind structures like roots, or when they are present on the lingual/palatal plates.…”

Diagnosis of Periodontal Diseases

“…This criterion provides for a nearly perfect test which maximizes both sensitivity and specificity within the error limits for detection of attachment loss. Conventional radiographs are not sensitive tools for this, because they cannot record the initial soft-tissue loss of attachment and have been shown to underestimate the amount of periodontal attachment or bone loss even after progression beyond initial stages (Theilade, 1960;Bender and Seltzer, 1961;Suomi6tfa/., 1968;Ainamo and Tammisalo, 1973;Lang and Hill, 1977;Greenstein et al, 1981). Histopathologic examination is the most accurate method, provided that both the tooth and attached soft tissue are removed together, but that is obviously an impractical approach to clinical diagnosis.…”
