Effect of Scaling and Root Planing on Alveolar Bone as Measured by Subtraction Radiography

Abstract

Scaling and root planing of diseased periodontal pockets can significantly increase radiographic alveolar bone density as demonstrated through the use of digital subtraction radiography.

Effects of Nonsurgical Periodontal Treatment on the Alveolar Bone Density

“…Few papers evaluated the results of NSPT on the ABD using computer analysis of the radiographs. Dubrez et al (7), Okano et al (8) and Hwang et al (9) reported that ABD increased significantly after NSPT, while Schmidt et al (6) did not find significant difference in the ABD after 2 years of observation. Hwang et al (9) were the authors whose method most closely resembled the one used in this study, Wilcoxon test was used to calculate the p value.…”

“…Previus studies (9,20,21) have suggested the use of control ROIs, but the authors did not use the same standard of positioning, also there is still no definition as to which would be the most specific control region. Maybe this region should be located even further from the defect and the treated area, as described by the Hwang et al (9) and Toback et al (21). However, those authors observed, respectively, an increase in the density of the apical and middle region of the defect, showing that both areas may have the density changed.…”

Effect and timing of non-surgical treatment prior to periodontal regeneration: a systematic review

“…It has now emerged that even non-surgical periodontal treatment of intrabony defects may result not just in clinical improvements but also in radiographic bone fill of the bony defects [9,10]. As such, one could speculate that if the baseline radiograph of a periodontal regeneration study was taken before NSPT, the final outcome might have been influenced by both NSPT and periodontal regenerative surgery (PRS) (rather than just PRS).…”

Management of Chronic Gingivitis with localized periodontitis by Nonsurgical (Phase I) Periodontal Therapy- A Case Report

“…Nonsurgical periodontal treatment usually leads to the formation of a long junctional epithelium [27] , and partial bone fill in an infrabony periodontal defect can also occasionally occur following careful SRP. Hwang, et al [28] reported an increase in bone density in sites with more than 3 mm vertical alveolar bone loss after SRP. Reduction of radiographic defect depth was a positively associated use of adjunctive antibiotics [29] .…”
