“…In contrast with previous studies 13,18,22 , in the present investigation, there were no instances of epithelial downgrowth in all sites. In similar defects, Andrade, et al 1 (2007) observed a correlation between the exposure of the membrane and the epithelial migration.…”

“…It is recognized that teeth with furcation involvement may undergo a more extensive and rapid clinical probing attachment loss and are lost with greater frequency than single-rooted teeth 18 . Although regeneration of periodontal tissue is the ultimate goal of periodontal therapy, regeneration is not a predictable healing outcome after conventional treatment.…”

Platelet-rich plasma in the treatment of Class II furcation defects: a histometrical study in dogs

Objective This study was designed to evaluate the potential adjunctive benefits of platelet-rich plasma (PRP) when used with guided-tissue regeneration (GTR) and bioactive glass (BG) in the treatment of Class II furcation lesions. Material and Methods Bilateral Class II furcation lesions were surgically created and allowed to become chronic in the mandibular third premolars of 9 dogs. The defects were randomly assigned to: A) GTR+BG and B) GTR+BG+PRP. Similar defects were created in the maxillary third premolars and received the same treatments after 45 days. Dogs were sacrificed 90 days after the first treatment. The histometric parameters evaluated were: connective tissue adaptation, new cementum, new bone, mineralized bone area, non-mineralized bone area, and residual BG particle area. Results Data analysis showed a superior length of new cementum and a greater mineralized bone area for group B in both periods (p<0.05). The non-mineralized bone area was greater in the control group (p<0.05) in both periods. Conclusion Within the limits of this study, it can be concluded that the use of PRP in the treatment of Class II furcation defects may enhance the amount of new cementum and provide a more mineralized bone in a shorter period of time.

“…3-4 weeks after gingivectomy or full thickness Haps, the maximum decrease in radioopacity was observed (Bergstrom & Henrikson 1974). Analyzing standardized radiographs by means of densitometry, the lowest densities were measured in the superficial furcation areas 2 months after treatment of furcation involvements (Payot et al 1987a & b).…”

The purposes of this study were to evaluate digitized images from standardized radiographs for quantitative changes in alveolar bone density following periodontal surgical procedures, and to correlate these changes to the changes in the clinical parameters P1I, GI, PD, AL. 14 crown-lengthening procedures for restorative purposes were performed in 13 patients and 15 modified Widman flaps were performed in 15 patients, providing 61 surgical interdental test sites and 61 matching controls. Standardized radiographs were obtained immediately post-operatively, and at 1 and 6 months postsurgically. Digitized images were obtained from the radiographs by means of a video camera linked to an image processor and a computer. Quantitative information regarding density changes within windows covering the interdental alveolar crest was obtained after superimposition and grey-level correction of images to be compared. The results indicated statistically significantly more density loss 4 to 6 weeks postsurgically at test sites treated by periodontal surgical procedures compared to corresponding controls. Significant differences in the remodelling activity between the patients exposed to crown lengthening procedures for restorative purposes and the periodontitis patients in the period 1 to 6 months postsurgically were evident. CADIA assessed differences in the tissue changes in the healing phase following periodontal surgical procedures, which were not detected by the clinical variables applied.

In a previous paper (1) we have described a new technique, Digital Image Ratio (DIR), which theoretically avoids some of the drawbacks of quantitative digital subtraction radiography. DIR allows one to directly compute and visualize bone-mass-ratio changes. In this second part, DIR analysis was used to examine 20 sites in 8 patients undergoing regenerative periodontal therapy. Standardized reproducible radiographs of these 20 sites were taken before and 12 months after surgery. Ten experimental sites were treated with two types of bone graft substitute (Natural Coral and Natural Coral + Collagen), and ten control sites by debridement alone.None of the experimental sites had a density ratio below 1, with 1 indicating no change.The range of error was evaluated to be ± 0.07 (0.93 -1.07). The experimental sites showed a mean increase in bone density of 18% (1.18), which increased to 23% (1.23) for sites filled with natural coral alone. All the control sites had values close to 1.00 (1.00 ± 0.07) except for three sites, which showed a loss of bone density ranging from 9 to 15%. It is thus possible to compare and quantify the changes in experimental and control sites in the same patient using the percent gain or loss of bone density. This demonstrates that DIR may be suitable for clinical applications and can be used in clinical analysis, where bone changes are expected.
