“…Reporting of outcome variables varied across included studies. Six of ten studies reported sensitivity and speci city (1,3,6,9,17,19) while accuracy was reported in half of the included studies [1], [3], [5], [7], [15]. Four of the included studies, measured qualitative radio-morphometric indices and linear measurements on the CBCT scans (2,9,18,20).…”

“…Moreover, the authors in these studies provided no information on the use and pre-speci cation of thresholds. However, the remaining three studies had a low risk of bias (6,9,19). Index test applicability concerns were low in all studies except one which had unclear applicability concern due to lack of information.…”

“…Studies included female participants only and used observational cross-sectional methodologies. Three studies were conducted in Syria (1,3,17), three in Brazil (6,9,18), one in Iran (19), one in Egypt (20), one in Korea(2) and one in the Unites States (21). All studies were published in English language.…”

“…All ten studies reporting on our outcomes of interest enrolled a total of 510 participants. Case-control was the most common method of sampling and was used in 6 of 10 studies (1)(2)(3)6,17,20) while cohort sampling was used in remaining four studies (9,18,19,21). Summary of included studies is reported in Table 2.…”

“…Shokri et al (2019) assessed the correlation between BMD determined by CBCT gray values and BMD determined by DEXA.The authors found that 61 asymptomatic patients (47.5%) had abnormal BMD based on the T-scores of the femoral neck while 55.7% of the patients had abnormal BMD based on the T-scores of lumbar spine. The correlations between the T-scores and the gray values of the maxillary incisor and tuberosity areas were signi cant(19).De Castro et al (2020) used cross-sectional and panoramic reconstructed images to evaluate mandibular cortical width (MCW) and cortical quality. The authors found signi cantly lower MCW values in osteoporotic women compared to women…”

Objective: To analyze the capability of cone-beam computed tomography (CBCT) to accurately identify low bone mass density in women.Methods: A systematic search of Medline, Embase, Scopus, Google Scholar, Cochrane Library, and Science Direct was conducted to identify the relevant articles. A detailed inclusion and exclusion criterion was developed and implemented to screen the abstracts. Full texts of the selected studies were then evaluated to establish their inclusion or exclusion in our review. Cochrane risk of bias criterion was used to determine the methodological quality of the included studies. All relevant data were extracted, and the results were summarized narratively.Results: Ten studies met out inclusion-exclusion criteria and were included in this systematic review. All of the included studies assessed primary research on the capacity of CBCT to accurately diagnose insufficient bone mineral density. The results indicated that CBCT has good sensitivity and specificity, and high accuracy in predicting osteoporosis. Four of the included studies measured qualitative values while others concentrated on quantitative values and found lower values in osteoporosis patients compared to osteopenic and healthy patients. All of these studies compared CBCT grayscale values with DEXA scores which strengthened our confidence in the accuracy of CBCT diagnostic capability.Conclusion: Given the common use of CBCT in dental practices and the high prevalence of osteoporosis in postmenopausal women, the evidence on the capacity of CBCT to predict osteoporosis is somewhat finite. Although this systematic review provides good evidence regarding the ability of CBCT for predicting osteoporosis, further research is needed to confirm the evidence and enhance its generalisability.
