A number of panoramic radiographic measurements have been associated with osteoporotic alterations. However, little is known about the differences in sensitivity and specificity among these measurements for screening low bone mineral density (BMD). Aim: To correlate and compare precision, sensitivity and specificity of panoramic radiomorphometric indices and fractal dimension (FD) for screening low BMD (i.e. osteopenia and osteoporosis). Methods: Sixty-eight female patients (42.78±15.59 years) were included in this study. Body mass index (BMI), mandibular cortical index (MCI), mandibular cortical width (MCW), FD and connectivity (C) were assessed. Low BMD was diagnosed by peripheral dual-energy X-ray absorptiometry (p-DXA). Non-parametric correlations were assessed among all variables. In addition, sensitivity and specificity of MCI, MCW and FD were estimated for screening low BMD. Results: Significant correlation was found between FD and BMI (p=0.013; r=0.269). In addition, FD was the most sensitive method for screening low BMD (70.8%, p=0.001). FD and MCI presented a significant and relatively high sensitivity, whereas MCW presented a high specificity for screening low systemic BMD Conclusions: Among the analyzed methods, FD and MCI offer a significant and relatively high sensitivity, whereas MCW offers a high specificity for screening low BMD.

Objectives: A systematic review and meta-analysis of diagnostic test accuracy studies was conducted to assess if the radiomorphometric indexes observed in panoramic radiographies could estimate reduced bone mineral density (BMD) similarly to standard technique the bone densitometry (dual energy X-ray absorptiometry) in females older than 30 years. Methods: A systematic search in four databases was conducted until January 2019. Two evaluators performed data extraction and evaluation of risk of bias independently, and agreement was achieved by consensus. Data were synthesized on a subgroup meta-analysis with a random effect model and the hierarchical summary receiver-operating characteristic curve was used to calculate pooled estimates of studies. Results: Thirty three studies were included and 12 different radiomorphometric indexes identified, including Mandibular Cortical Index (MCI). The final number of cases pooled for the analysis was 5266 females.The MCI for BMD loss (osteopenia) presented values of sensitivity 0.81 [95% confidence interval (CI), 0.78–0.84] and specificity 0.48 (95% CI, 0.45–0.50), while for osteoporosis sensitivity 0.35 (95% CI, 0.30–0.40) and specificity 0.88 (95% CI, 0.86–0.90). The mandibular cortical width presented values of sensitivity 0.58 (95% CI, 0.40–0.73), specificity 0.73 (95% CI, 0.60–0.83) for osteopenia, while for osteoporosis sensitivity 0.57 (95% CI, 0.36–0.76) and specificity 0.83 (95% CI, 0.68–0.92). Due to the high sensitivity, MCI presented a potential value as a screening tool for initial BMD loss (osteopenia), once tests presenting high sensitivity are described as rarely missing subjects with the disease. To the other hand, MCI to osteoporosis and Mandibular Cortical Width for both conditions are not recommended because presented specificity higher than sensitivity. Conclusion: The MCI can be recommended as a feasible tool to screen initial BMD loss (osteopenia) in females above 30 years old using panoramic radiography exams.
