BACKGROUND |
The aim of this study is to evaluate the levels of osteoclastogenesis-related factors (soluble receptor activator of nuclear factor-kappa B ligand [sRANKL] and osteoprotegerin [OPG]) in gingival crevicular fluid (GCF) from subjects with poorly and well-controlled type 2 diabetes and chronic periodontitis before and aft... |
METHODS |
Eighteen subjects with well-controlled diabetes (glycated hemoglobin [HbA1c] levels ≤ 8%) and 20 subjects with poorly controlled diabetes (HbA1c levels >8%) were enrolled in this study. All subjects were submitted to non-surgical periodontal therapy. GCF sampling and clinical periodontal parameters were assessed at bas... |
RESULTS |
Total amounts and concentrations of sRANKL and RANKL/OPG ratios were higher in poorly controlled subjects than in well-controlled subjects at baseline and 3 and 6 months post-therapy (P <0.05). In addition, RANKL/OPG ratios decreased in well-controlled subjects (P <0.05) but not in poorly controlled subjects (P >0.05) ... |
CONCLUSION |
RANKL/OPG ratios in untreated and treated periodontitis sites may be negatively influenced by poor glycemic control in subjects with type 2 diabetes.Design and fabrication of a glass waveguide optical add-drop multiplexer by use of an amorphous-silicon overlay distributed Bragg reflector. |

OBJECTIVE |
To compare the diagnostic accuracy of detailed tomography using the Scanora system with that of conventional periapical radiography for detecting periapical and periodontal lesions. |
METHODS |
We selected for comparison 243 periapical and 322 periodontal sites in 177 patients. Five observers independently assessed radiographs for the presence or absence of the following lesions: periapical bone changes, widening of apical and marginal ligament space, crestal erosion, vertical bone loss, furcation involvement... |
RESULTS |
ROC analysis demonstrated no significant differences in the overall interpretation of either disease. Periapical radiography was superior (p < 0.05) to tomography for the detection of calculus. The sensitivity of tomography for periapical pathology was 87%, and 70% for periapical radiography. Sensitivities for periodon... |
CONCLUSION |
Detailed tomography and periapical radiography performed equally well for the overall diagnosis of periapical and periodontal lesions. Tomograms differed substantially from periapical radiographs in both sensitivity and specificity for detecting periapical lesions in posterior regions. The energy imparted during detail... |
