J Oral Biol Craniofac Res 2024; 14:273-279. [PMID: 38559588 PMCID: PMC10979266 DOI: 10.1016/j.jobcr.2024.03.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2023] [Revised: 02/10/2024] [Accepted: 03/08/2024] [Indexed: 04/04/2024] Open
Abstract
Purpose The purpose of the study is to evaluate the mandibular trabecular pattern in pre- and postmenopausal age women. By analysing the strut, fractal, grey level co-occurrence matrix, and radio-morphometric indices in the panoramic radiograph. Method Panoramic radiographs from 2019 to 2022 were used to assess pre- and postmenopausal women's bone mineral density. A total of 272 panoramic radiographs, which exhibited clear visibility of the mental foramen on both sides without any blurring, motion artefacts, surgical errors, overlapping hyoid bone, or inferior mandibular cortex, were divided into two groups. Group A (136 premenopausal women) and Group B (136 postmenopausal women). It is a retrospective study that is non-interventional/observational in design. Strut features, fractal dimensions, a grey-level co-occurrence matrix, and radio morphometric indices were used to investigate bone texture in an image processing program. The mean difference between group variables was calculated using an independent sample t-test/unpaired t-test. Results Pre-menopausal women had a mean age of 38.83 ± 6.01 years, while postmenopausal women had a mean age of 68.26 ± 8.31 In the postmenopausal group Four regions of interest exhibited fractal dimensions with a P value of less than 0.01 and GLCM features including contrast (0.812), correlation (0.230), energy (0.215), and homogeneity (0.322). Strut features of the four regions showed that 15 of 19 characteristics were significantly different. Conclusion Orthopantomogram is useful in screening for osteoporosis. Strut, radio-morphometric indices, and fractal analysis can assess bone texture and quality. Future research incorporating artificial intelligence can revolutionize image analysis and support clinical decision-making.

Abstract
This review aims to evaluate the accuracy of various mandibular radiomorphometric indices in comparison with DEXA BMD measurements in the diagnosis of osteopenia and osteoporosis based on a meta-analysis of the sensitivity and specificity of the indices. PRISMA statement was followed. The materials for analysis were collected in August 2023 by searching three databases: PubMed Central, Web of Science, and Scopus. The selection of studies consisted of three selection stages, and 64 articles were finally obtained. Quality assessment was performed with the QUADAS-2 tool, and the general methodological quality of retrieved studies was low. Statistical analysis was performed based on 2 × 2 tables and estimated sensitivity and specificity were obtained using SROC curves. The most used indices were MCI, MCW and PMI. The best results in detecting reduced BMD obtained for MCW ≤ 3 mm, estimated sensitivity and specificity were 0.712 (95% CI, 0.477-0.870) and 0.804 (95% CI, 0.589-0.921), respectively. The most prone to the risk of bias is the MCI due to the examiner's subjectivism. Radiomorphometric indices of the mandible can be useful as a screening tool to identify patients with low BMD, but should not be used as a diagnostic method. Further research needs to focus on analysing the ability of the indices to detect osteoporosis and also in combination the indices with clinical parameters.

Abstract
BACKGROUND Hemophilia is associated with an increased risk of developing osteoporosis and osteopenia. The aim of the study was to interpret the usefulness of fractal analysis of the trabecular bone of the mandible (FD) and selected radiomorphic indices (the antegonial index (AI) and Klemetti index (KI)) to assess the risk of reduced bone mineral density (BMD) in patients with hemophilia A/B. METHODS The study group consisted of 50 patients with type A/B hemophilia. The control group consisted of 25 males without congenital bleeding disorders. The patients had a panoramic radiograph taken with the same X-ray machine (Vistapano S, Durr Dental, Bietigheim-Bissingen, Germany). The AudaXCeph software (Audax d.o.o., Ljubljana, Slovenia) was used to evaluate the AI index, and the ImageJ, software with a specially prepared script, was used to evaluate the FD. The mandibular cortex was assessed distal to the mental foramen using the Klemetti index. RESULTS There were no statistically significant differences between the AI, KI and FD values between the study group and the control group. CONCLUSIONS This study indicated the lack of usefulness of AI, KI and fractal analysis in identifying patients with hemophilia at risk of reduced bone mass.

Abstract
OBJECTIVES To analyze factors predicting mandibular cortical width (MCW) and mandibular cortical index (MCI) in adult females and males. MATERIAL AND METHODS Data on 427 females and 335 males aged 40-84 from The Tromsø study: Tromsø7 were used. T-score, age, menopausal status (for females), remaining teeth, and periodontal status were analyzed in linear and logistic regression analyses as predictors of MCW and MCI, respectively. RESULTS T-score, age, and the number of remaining teeth significantly predicted MCW in females but not males. Standardized β coefficients were 0.286, -0.231, and 0.131, respectively. The linear regression model explained 24% of MCW variation in females. MCI in females was significantly predicted by T-score, age, and remaining teeth with the Wald values of 9.65, 6.17, and 5.83, respectively. The logistic regression model explained 16.3-23% of the variation in MCI in females. In males, T-score was the only significant predictor of the eroded cortex, and the logistic model explained only 4.3-5.8% of the variation in MCI. CONCLUSIONS The T-score demonstrated a stronger relationship with MCW and MCI than other factors in females, which supports the usefulness of those indices for osteoporosis screening. Conversely, the T-score exhibited no association with MCW and remained the only significant predictor of MCI in males, yet to a lesser extent than in females. CLINICAL RELEVANCE Understanding factors affecting mandibular cortical morphology is essential for further investigations of MCW and MCI usefulness for osteoporosis screening in females and males.

Abstract
OBJECTIVES Sickle cell disease (SCD) can cause osteoporotic changes in the jaw bones. In this study, it was aimed to evaluate possible bone changes using fractal analysis (FA) and morphometric analyses in dental panoramic radiographs of children and adolescents diagnosed with both homozygous and heterozygous forms of SCD. METHODS Sixty-five individuals (33 SCD, 32 controls) aged 6-17 years were included in the study. Four separate areas of interest (ROI) were selected for the right and left sides of all panoramic radiographs, and the FA value of the ROIs was calculated. Mandibular cortical width (MCW), panoramic mandibular index (PMI) and mandibular cortical index (MCI) and were evaluated. Data were statistically analyzed and p < 0.05 was accepted for statistical significance. RESULTS Fractal values of right and left ROI1 (the center of the mandibular angle.) and ROI4 (the cortical bone), and right ROI2 (the middle of the mandibular ramus) were statistically lower in the case group (p < 0.05). Right ROI2 and ROI4 fractal values of individuals in the case group were lower than those on the left side (p < 0.05). While MCI categories did not differ from the case-control group (p > 0.05), PMI and MCW values were lower in the case group (p < 0.05). All evaluated parameters did not differ according to age and gender (p > 0.05). CONCLUSION The results of this study showed that SCD affects the mandible. FA, MCW and PMI parameters can be used to detect early osteoporotic changes in the disease.

Abstract
OBJECTIVES This study aims to quantitatively evaluate the effects of bisphosphonate use duration and route of administration on mandibular cortical and trabecular bone in postmenopausal women. STUDY DESIGN Ninety postmenopausal women over the age of 50 were included in this study. Trabecular bone density was specified numerically by fractal dimension (FD) in the region of interest selected on the panoramic radiograph. The width of the mandibular cortical (MCW) bone under the mental foramen of the mandible was measured. Mann-Whitney U test was used for parameters that did not show a normal distribution. Spearman rho correlation test was used to determine the relationship between continuous measurement parameters. RESULTS It was observed that FD and MCW of dentate and edentate individuals using bisphosphonate were statistically significantly lower than those of healthy individuals (P < .05). There was no significant correlation was found between the duration of use of bisphosphonates and the fractal values obtained from the relevant regions of the mandible (P > .05). CONCLUSION Fractal dimension was found to be lower in oral bisphosphonate use than in intravenous bisphosphonate use. The width of the mandibular cortical bone values was found to be lower in individuals using bisphosphonate than in healthy individuals. Fractal dimension and MCW may benefit clinicians as quantitative parameters in panoramic radiography in the diagnosis of osteoporosis.

Abstract
OBJECTIVE This study aimed to investigate and compare the mandibular radiomorphometric characteristics of patients with unilateral or bilateral cleft lip and palate (CLP) with those of individuals without CLP and to determine whether there was a difference. DESIGN Retrospective cohort study. SETTING Orthodontic Department in Faculty of Dentistry. PATIENTS AND INTERVENTIONS Mandibular cortical bone thickness was measured on high-quality panoramic radiographs taken from 46 patients with unilateral or bilateral CLP aged 13-15 years and 21 control patients. MAIN OUTCOME MEASURES Three radiomorphometric indices [antegonial index (AI), mental index (MI), and panoramic mandibular index (PMI)] were measured bilaterally. AutoCAD software was used for MI, PMI, and AI measurements. RESULTS Left MI values were significantly lower in individuals with unilateral cleft lip and palate (UCLP; 0.029 ± 0.04) than in individuals with bilateral cleft lip and palate (BCLP; 0.033 ± 0.07). In addition, right MI values of individuals with right UCLP (0.26 ± 0.06) were significantly lower than those of individuals with left UCLP (0.34 ± 0.06) or BCLP (0.32 ± 0.08). No difference was observed between individuals with BCLP and left UCLP. These values did not differ between groups. CONCLUSIONS Antegonial index and PMI values did not differ between individuals with different types of CLP or when compared with control patients. In patients with UCLP, cortical bone thickness was found to be reduced on the cleft side compared to the intact side. Patients with UCLP with a right-sided cleft had a more substantial decrease in cortical bone thickness.

Abstract
Purpose Orthopantomographic (OPG) indices are considered tools for early screening for low Bone Mineral Density and Osteoporosis. This tool is being used in the western population, and they have developed their reference values for all the OPG indices. The current study aimed to check the validity of the reference values for OPG indices in the Indian population. Material and methods A cross-sectional study was conducted on 325 participants, and they were recruited in two sets. Dataset one of 130 aged 20-30 years and dataset two of 195 participants aged 40-60 years. OPG was performed, and indices such as Mental Index (MI), Panoramic Mandibular Index (PMI), Gonial Index (GI) and Antegonial Index (AI) were measured. Values obtained in our study were compared with the established OPG indices for the Indian and Western populations. Results The mean age of participants in dataset one to develop references was 23.5 ± 2.5 years. Females had a significantly lower MI, PMI, and AI than males (p < 0.05). MI was significantly higher in validation dataset one males than females (p < 0.05). A good agreement was found in MI and PMI of the two references (p < 0.05). Conclusions The reference values derived from this study for MI, PMI, GI and AI are 3.50,0.27,1.10, 2.50, respectively. Compared with previous studies in Indian and western populations, these references were significantly lower.

Abstract
OBJECTIVE The aim of this study is to assess the mandibular bone structures of multiple myeloma (MM) patients on panoramic radiographs using fractal analysis (FA) and radio-morphometric indices. METHODS The study group consisted of 67 MM patients, and the control group consisted of 67 individuals without any systemic disease. The mandibular cortical index (MCI) classification, antegonial index (AGI), gonial index (GI), mandibular cortical width (MCW), panoramic mandibular index (PMI) and fractal dimensions (FD) were evaluated on panoramic radiographs. FD measurements were made by identifying 4 related areas. Shapiro-Wilk test was used to determine the normal distribution of the data. Chi-square and independent t tests were used to compare the findings between the two groups. RESULTS The FD values of the study group in ROI1, ROI2, ROI3, ROI4 regions and GI values were found to be statistically significantly lower than the control group (p < 0.001). There was no statistically significant difference between the two groups in terms of AGI, MCW and PMI values (p > 0.05). While C1 was the most common type in the control group, C2 was the most common type in the study group. C2 and C3 were detected more in the study group than in the control group (p < 0.001). CONCLUSION Our study showed a consensus with the studies advocating that fractal analysis and radio-morphometric indices are methods that can be used to determine mandibular bone density. The low bone density of MM patients is a condition that physicians should be aware of for interventional dental procedures.

Abstract
Breast cancer (BC) survivors treated with aromatase inhibitors (AIs) commonly show several pathological issues, including poor oral health, bone health impairment, and vitamin D deficiency. However, to date, oral health issues in BC survivors treated with AIs have been poorly investigated and their relationship with vitamin D deficiency are far from being understood. This study aimed to evaluate the correlation between oral health and vitamin D status in BC survivors undergoing treatment with AIs through a machine learning approach. In this cross-sectional study, we included post-menopausal BC women with vitamin D deficiency undergoing AIs therapy. The outcome measures were the following: oral health indexes as the Decayed, Missing, and Filled Permanent Teeth Index (DMFT); serum levels of 25(OH)D3; Bone Mineral Density (BMD); and the diagnosis of osteoporosis. We included 41 post-menopausal BC women, mean aged 66.10 ± 8.47 years, with mean serum levels of vitamin D of 14.63 ± 6.62 ng/mL. Furthermore, 56.10% of patients had a diagnosis of osteoporosis and 36.59% were osteopenic. DMFT was significantly related to smoking (p-value = 0.005) and dental floss use (p-value = 0.001). There was a significant correlation between DMFT and vitamin D levels (Pearson’s r: −0.73; p-value = 0.001). The regression machine learning model showed that vitamin D status and the use of dental floss were the most relevant variables in terms of correlation with DMFT. In conclusion, vitamin D deficiency, inadequate use of dental floss, and smoking had a negative impact on oral health in BC women. Thus, vitamin D deficiency screening and supplementation and a prompt oral rehabilitation plan should be suggested and implemented in the complex treatment framework of BC survivors undergoing treatment with AIs.

Abstract
Background: The study aimed to evaluate radiomorphometric indices derived from panoramic X-rays and selected blood markers of bone turnover and neutrophil extracellular traps, with a view to identifying hemophilic patients at risk of developing osteoporosis. Methods: The study consisted of 50 adult men with hemophilia A and B (mild, moderate, and severe). The control group consisted of 25 healthy adult men. In both groups, blood samples were collected to determine concentrations of citrullinated histone H3 (CH3) and osteocalcin (BGLAP) with ELISA tests, and panoramic X-rays were obtained. Images were imported into AudaXCeph software to calculate two radiomorphometric indices: mental index (MI) and panoramic mandibular index (PMI). Concentrations of BGLAP and CH3 were compared with MI and PMI values in patients with and without hemophilia. Results: There were statistically significant differences in BGLAP, CH3, and PMI between the study and the control group (p < 0.05). Multivariate logistic regression analysis showed a predictive value for PMI, BGLAP, and CH3.The ROC curve with cutoff point (Youden index) at 0.40—PMI was calculated. No correlation was observed for the PMI index in any particular subgroup of patients. No correlation between MI and BGLAP/CH3 was observed. Conclusions: Simultaneous use of PMI value and BGLAP and CH3 levels may allow the identification of patients with hemophilia who requirea detailed diagnosis of osteoporosis with DXA.

Abstract
Abstract
Background
DEXA scan could be unavailable at some health centers, and radiologic examination of the mandible and oral cavity is considered more commonly used radiologic test that can predict, diagnose, or even follow-up on any defect in bone mineralization. The aim of this study was to elucidate the ability of panoramic radiograph to detect osteoporosis in rheumatoid arthritis patients and correlate panoramic mandibular index with RA disease activity and severity parameters.
Results
The sensitivity of panoramic mandibular index for diagnosis of osteoporosis was 96% in group Ι (primary OP) and 70% in group ΙΙ (RA patients). The positive predictive value of PMI was 67% in group Ι and 55% in group ΙΙ. The negative predictive value of PMI was 34% in group Ι and was 46% in group ΙΙ. The cutoff value of PMI for diagnosis of OP was ≤ 0.31 in group Ι and ≤ 0.17 in group ΙΙ. In group I, there were significant correlations between panoramic mandibular index and patient’s ages, weights, T score at L1-4, T score at femoral neck, and T score at forearm while there were insignificant correlations between PMI and patients’ heights. In group ΙΙ, there were significant correlations between PMI, patients’ ages, weights, disease durations, SHARP score, ESR, RF, T score at L1-4, T score at femoral neck, and T score at forearm, while there were insignificant correlations between PMI and patients’ heights, DAS, and CRP.
Conclusions
Panoramic radiography could have a potential usability in the diagnosis of osteoporosis in rheumatoid arthritis patients regardless of displaying insignificant correlation with disease activity.

Abstract
Background This prospective study was designed to evaluate the effects of bruxism on mandibular cortical bone using radiomorphometric indices on digital panoramic radiographs. Materials and Methods The mandibular cortical index (MCI), mental index (MI), and panoramic mandibular index (PMI) were measured on digital panoramic radiographs and evaluated for 128 bruxers (66 female, 60 male) and 128 control subjects. The data were analyzed statistically using intraclass correlation coefficients (ICC), Kappa statistics, Chi-square test, Kolmogorov-Smirnov test, independent t-test, and Pearson's correlation analysis. Results There was no difference between the groups in terms of MCI type (P > 0.05). While mean MI values were significantly higher in bruxers than the control group (P = 0.007), the difference between groups in mean PMI values was nonsignificant (P > 0.05). In both groups, the C1 type was more prevalent in females than in males (P = 0.001). Females showed significantly lower mean MI values than males in both groups (P ≤ 0.040). However, the difference between genders in mean PMI values was not significant (P > 0.05). Conclusions MI measurements may be useful when radiomorphometric indices are to be used for the diagnosis or follow-up of bruxism in the mandible. Among radiomorphometric indices, MI and MCI values are affected by gender differences.

Abstract
OBJECTIVE The aim of the present study was to compare radiomorphometric measurements on panoramic images of patients with hyperthyroidism (HT) to those of a control population. STUDY DESIGN In this retrospective study, the mental index (MI), inferior panoramic mandibular index (PMI), antegonial index (AI), gonial index (GI), and mandibular cortical index (MCI) were evaluated on dental panoramic radiographs (DPRs) of 40 patients with HT and 40 healthy age- and sex-matched individuals and compared between the groups. Quantitative data (MI, PMI, AI, and GI) were analyzed with the Student t and Mann-Whitney U tests. Categorical data (MCI) were analyzed with the chi-square test. RESULTS Statistically significant differences between the patient and control groups were found for inferior PMI (P = .001) and AI (P = .017) values, with smaller mean values among the patients. However, the measurements of MI (P = .59) and GI (P = .164) and the MCI distribution (P = .13) were similar in both groups. CONCLUSIONS Evaluating the radiomorphometric indices of inferior PMI and AI on the DPRs of patients with HT who are at high risk of secondary osteoporosis could be helpful in the early diagnosis of osteoporotic changes and in formulating surgical treatment plans.

Abstract
INTRODUCTION We present here a literature review focusing on the repercussions of osteoporosis on the oral and maxillofacial complex. Osteoporosis is a silent metabolic disorder characterized by reduced bone mineral density (BMD), which can lead to bone fractures, particularly affecting elderly women. The prevalence of this disease has increased significantly worldwide, and since it accelerates bone resorption also in the jaw bones, some attention has been paid to possible oral and maxillofacial manifestations. MATERIALS AND METHODS The databases PubMed and Google Scholar were searched for reports of oral and maxillofacial changes related to osteoporosis. RESULTS Several parameters evaluating bone changes in panoramic radiography have been proposed to estimate osteoporosis-related BMD loss, but they tend to warn about the possibility of osteoporosis, rather than being diagnostic criteria. Meanwhile, it seems that osteoporosis-related BMD loss could delay alveolar bone healing and potentiate bone loss in periodontal disease. CONCLUSION Even though orofacial bones are not compromised by osteoporosis as much as the axial/appendicular skeleton, a regular dental follow-up of osteoporotic patients is advised, especially in the case of periodontal disease and maxillofacial surgery. Further controlled longitudinal studies considering the site-specificity of osteogenesis would be helpful regarding this issue.

Abstract
Osteoporotic fractures are associated with an increased risk of subsequent fractures, a higher rate of mortality, and incremental medical costs. Incidental findings, which include some measurements related to the mandibular inferior cortex and the alveolar trabecular bone pattern of the mandible determined on panoramic radiographs, are considered to be a useful tool for identifying asymptomatic individuals at risk of having osteoporosis and/or fragility fractures. We undertook a worldwide literature survey and present the following clinical recommendations. Postmenopausal female dental patients with a mandibular inferior cortical width of less than 3 mm on panoramic radiographs may be at risk of having low skeletal bone mineral density (BMD) or osteoporosis, but not fragility fractures. In addition, those with a severely eroded mandibular inferior cortex may have an increased risk of having low skeletal BMD, osteoporosis, and fragility fractures. The alveolar trabecular bone pattern of the mandible might be useful for identifying female dental patients at risk of having fragility fractures, although further investigation is necessary to confirm this possibility. These incidental findings on panoramic radiographs, when used for identifying asymptomatic postmenopausal female patients at risk of having osteoporosis in general dental practice, may be helpful in reducing the incidence of first fractures, with a consequent reduction in the secondary fractures, medical costs, and mortality associated with osteoporotic fragility fractures, without incurring any additional cost.

Abstract
OBJECTIVE The aim was to compare dental and skeletal indices in panoramic radiography between patients undergoing haemodialysis, peritoneal dialysis and age- and sex-matched control group. METHODS In this comparative cross-sectional study, quantitative Indices including Antegonial Index (AI), Mental Index (MI), Panoramic Mandibular Index (PMI) and qualitative indices including Mandibular Cortical Index (MCI) and Trabecular Pattern (TP) were evaluated in panoramic images of 32 haemodialysis patients, 14 patients under peritoneal dialysis and 52 healthy individuals. The images were also investigated for pulp canal calcification, pulp stones, soft tissue calcification, changes in or loss of lamina dura, radiolucencies associated with brown tumour and ridge resorption. The indices were compared between the three groups and were investigated for association with the patients' blood test parameters and their diseases causing chronic renal failure (CRF). Intraobserver agreement for the 2-week interval of assessment was calculated for the indices. RESULTS MI (p = 0.574) and PMI (p = 0.100) were not significantly different, but AI (p = 0.01), MCI (p < 0.001) and TP (p = 0.002) were significantly different between the two case groups and the control group. The prevalence of pulp calcification (p = 0.03) and ridge resorption (p = 0.005) was higher in the haemodialysis group. Soft tissue calcification (p = 0.85) and lamina dura changes (p = 0.9) showed no significant difference. Brown tumours were observed in only one case in the haemodialysis group. CONCLUSIONS AI, MCI and TP showed a reduction in mineral density of the cortical and trabecular bone in CRF patients and more severely in patients under haemodialysis than those under peritoneal dialysis.

Abstract
OBJECTIVES The purpose of this study is to evaluate normal ranges of cortical bone Hounsfield units indices through cone beam CT images, and to investigate their relationships with age and sex. METHODS 700 adult human cone beam CT images were evaluated retrospectively, and divided into 4 age groups. Six different cortical bone Hounsfield unit measurements were applied bilaterally, where gender and age were recorded. Collected data were subjected to statistical analysis and ANOVA tests were used for various comparisons. RESULTS The cortical bone measurements between female and male patients were significantly different (p<0.05). Cortical bone thickness indices showed greater values in male patients compare to female patients (p<0.05). Quantitative mandibular indices were significantly lower in first age group (18-30 years) than other three older age groups (p<0.01). CONCLUSION The results of this study seems to propose a persistent alteration in the mandibular cortical bone with age and that this influced by sex. Further studies with larger patient groups are needed to clarify and understand these mandibular indices.

Abstract
OBJECTIVES Selective serotonin reuptake inhibitors (SSRI) are a group of drugs that selectively and strongly block the serotonin transporter. Aim of this study was to evaluate the mandibular bone structure of patients who are using SSRIs with fractal analysis and panoramic morphometric indices [mandibular cortical width (MCW), panoramic mandibular index (PMI) and Klemetti index (KI)] and to compare with control group. METHODS Patients who declared using SSRIs for more than six months had been included in the study group. In total, 212 dental panoramic radiographs (DPR) were assessed. For fractal analysis; three regions of interest (ROIs) were determined: ROI1 and ROI2 were chosen within trabecular bone, ROI3 was selected from cortical bone. MCW, PMI, and KI were obtained from DPRs. The study group was categorized into five subgroups of various SSRIs. The fractal dimension (FD) values and panoramic morphometric indices of these subgroups were also compared. RESULTS There was no significant difference between the groups for age and gender (p = 0.57, p = 0.5). There were significant differences in the mean FD values between the study and control groups both for the ROI1 and ROI2 (p < 0.01, p < 0.01). There was no significant difference between the groups for the mean FD value of ROI3, MCW, PMI and KI (p = 0.93, p = 0.98, p = 0.74, p = 0.06). There were no significant differences for all the values between the SSRI subgroups (p = 0.52, p = 0.7, p = 0.76, p = 0.24, p = 0.31, p = 0.08) CONCLUSIONS: Trabecular rich sites of the mandible were found to be affected by SSRI usage.

Abstract
OBJECTIVE This study aimed to evaluate the radiomorphometric indexes and fractal dimension (FD) on dental panoramic radiography (DPR) of Thalassemia Major (TM) patients. METHODS In 59 TM patients and in 59 healthy control subjects, mandibular cortical index (MCI), mandibular cortical width (MCW), panoramic mandibular index (PMI), and FD of four different regions (FD1-4) were evaluated and compared using DPRs. RESULTS The distribution of MCI in TM patients was similar to control subjects (p > 0.05). The mean MCW was significantly lower in TM patients (p = 0.001). There was no significant difference in PMI between TM patients and control subjects. The mean of FD measured in the supracortical area above the angle of mandible (FD2), in the anterior to the mental foramen (FD4) and mean FD of four different regions was significantly lower in TM patients (p = 0.003, p = 0.001, and p = 0.014, respectively). CONCLUSIONS The radiomorphometric indices and fractal dimensions evaluated in the panoramic radiograph are capable of identifying thalassemia patients' jaw bone, and the results of DPR scanning can be used to refer these patients to appropriate medical investigation.

Abstract
Objective: Using cone-beam computed tomography (CBCT) images, the aim of the study was to evaluate the usefulness of measuring radiographic density of the axis vertebra (RDAV) in patients at risk of osteoporosis. Materials and Methods: Two hundred and forty-seven old patients (109 males and 138 females) aged between 50 and 80 years (mean age: 59.68 ± 7.27) were examined by CBCT. Using InVivoDental, v. 5.0 (Anatomage Inc., San Jose, CA), RDAV and mental index (MI) were measured twice and correlated using Pearson's correlation coefficients. Patients were divided into two categories: high risk and low risk of osteoporosis using 3.1 mm of MI as a cutoff value, and the mean value of RDAV was compared and correlated using independent samples’ t-test and regression analysis. Receiver-operating characteristic (ROC) curve analysis was also used to examine the predictive power of RDAV. Results: The mean value of RDAV was moderately correlated with MI (r = 0.32), and in patients at low risk of osteoporosis, the mean value of RDAV was significantly higher than in patients at high risk of osteoporosis. In multivariate binary logistic regression, the odds of being at risk of osteoporosis decreased by 1% with one unit increase in RDAV (odds ratio = 0.988, 95% confidence interval: 0.983–0.993; P < 0.005). ROC analysis showed that the mean value of RDAV had a high predictive power for predicting patients at risk of osteoporosis (area under the curve = 0.761 for females and 0.649 for males). Conclusions: Measuring RDAV is considered useful in predicting patients at risk of osteoporosis.

Abstract
STATEMENT OF THE PROBLEM Reduced bone mineral density (BMD) generally affects postmenopausal women and it is classified into moderate (osteopenia) and significant osteoporosis. Based on digital panoramic radiographs (DPRs), several quantitative and qualitative assessment methods have been proposed for the diagnosis and evaluation of bone changes and as a predictor of BMD. PURPOSE The aim of this study was to compare mandibular cortical width (MCW) and mandibular cortical index (MCI) derived from DPRs in evaluating the BMD in osteopenic and osteoporotic post-menopausal women. MATERIALS AND METHOD In this cross-sectional study, the BMD assessment was performed using dual-energy X-ray absorptiometry (DEXA). Then, patients were divided into two groups: osteopenia and osteoporosis based on WHO criteria. Two types of T-scores including TT (trabecular) for lumbar spine, TC (cortical) for femoral neck and finally, MCW and MCI were measured based on DPRs. RESULTS Fifty females with the average age of 57.64±6.03 years were entered into the study. MCW significantly correlated with BMD (p< 0.05). Pearson correlation coefficient test revealed that there was almost significant relationship between MCI and BMD (p= 0.079). The area under the curve (AUC) in ROC suggested that there was a close overlap between MCW (0.773) and TC (0.783), but TT had the greatest AUC (0.996). CONCLUSION The results showed that MCW is an appropriate index of osteoporosis in post-menopausal women. Although the prediction of osteoporosis is poorer at the femoral neck than lumbar spine, MCW can serve as a screening tool for osteoporosis in this area.

Abstract
Background Many oral presentations of osteoporosis-a bone metabolic disease-were recorded. Thus, we aimed to assess panoramic radiomorphometric indices with bone mineral density (BMD) values among Saudi postmenopausal women and its importance in the prediction of osteoporosis. Methods A total of 431 Saudi women were enrolled in this study. Panoramic radiographs were obtained at the time of BMD measurement. Subjects were fatherly classified into; normal BMD, osteopenia, and osteoporosis groups. Serum follicle-stimulating hormone, luteinizing hormone (LH), estradiol (E2), 25-hydroxy-vitamin D (25[OH]D) and intact-parathyroid hormone were measured. Moreover, serum creatinine, calcium, and phosphate, together with serum osteocalcin (s-OC), procollagen type I N-terminal propeptide (s-PINP) and cross-linked C-terminal telopeptide of type 1 collagen (s-CTX) were measured. Receiver-operator curve (ROC) curve analysis for use of mandibular cortical width (MCW), panoramic mandibular index (PMI), and maxillary-mandibular ratio (M/M ratio) to differentiate women with osteoporosis or osteopenia from normal subjects was calculated. Cut off values of 4.6 at T score <−1 and 4.1 at T score ≤−2.5 were used. Results Body mass index is significantly low in the osteoporotic group. There is no significant difference in serum levels of LH, E2, calcium, phosphate, and 25(OH)D between the studied groups. Moreover, s-OC, C-terminal propeptide of procollagen type I, s-PINP, s-CTX, and urinary-CTX are significantly higher in osteoporosis than normal and osteopenia groups. ROC curve analysis revealed that MCW and PMI showed significant data while M/M ratio is non-significant. Conclusions It could be concluded that MCW as an important panoramic radiographic parameter can be used for prediction and diagnosis of osteoporosis in postmenopausal Saudi women with low BMD.

Abstract
Objective: Using cone beam computed tomography (CBCT) images, the aim of the study was to evaluate the usefulness of measuring bone density of mandibular condyle (BDMC) in patients at risk of osteoporosis. Materials and Methods: Two hundred and four mandibular condyles (46 condyles from males and 158 condyles from females) were examined by CBCT. Using inVivo software (Anatomage, San Jose, Calif), BDMC and mental index (MI) were measured by two observers and correlated using Pearson's correlation coefficients. Patients were divided into high risk and low risk of osteoporosis using 3.1 mm of MI as a cutoff value, and the mean value of BDMC was compared and correlated using independent samples t-test and regression analysis. Receiver-operating characteristic (ROC) curve analyses were also used to examine the predictive power of BDMC. Results: The mean value of BDMC was moderately correlated with MI (r = 0.38), and in female patients at low risk of osteoporosis, the mean value of BDMC was significantly higher than in patients at high risk of osteoporosis. In multivariate linear regression analysis, being at risk of osteoporosis is significantly affected by BDMC, age, and gender. ROC analysis showed that the mean value of BDMC had a moderate predictive power for predicting patients at risk of osteoporosis (area under the curve = 0.621 for females and 0.649 for males). Conclusions: Measuring BDMC is considered useful in predicting patients at risk of osteoporosis.

Abstract
In this study we analyzed the mandibular cortical bone of patients with type 1 diabetes mellitus (T1DM) and non-diabetic. Fifty patients with T1DM and 100 non-diabetic ones paired by age and gender were analyzed. Two double-blinded observers evaluated 150 digital panoramic images of both groups. The mandibular cortical bone was analyzed using the Mandibular Cortical Index (MCI), Mental Index (MI), Gonial Index (GI), Antegonial Index (AI) and Upper and Lower Panoramic Mandibular Indexes (UPMI and LPMI), with the aid of RADIOIMP® software. Influence of T1DM in the morphology of the mandibular cortical bone was studied based on obtaining data related to T1DM diagnosis time, blood glucose level, T1DM control and the presence of chronic complications. Collected data were submitted to descriptive (mean and standard deviation) and inferential analyzes (Pearson's chi-squared test and Fisher's exact test) (p≤0.05). According to the MCI, individuals with T1DM had higher frequencies of mandibular cortical alterations, in both sexes and all age groups (p<0.01). For quantitative indexes, MI, GI, AI, UPMI and LPMI, female patients showed statistically significant differences for GI and AI, while male patients had statistically significant differences for all indexes (p<0.05), presenting the individuals with TDM1 inferior measures. Individuals with poor T1DM control showed significantly higher frequency of mandibular cortical alteration (92.3%), with lower means for MI, GI, AI and LPMI (p≤0.05). In conclusion, patients with T1DM showed decrease in the mandibular cortical bone when compared to non-diabetic ones, indicating that poor disease control is associated with these alterations.

Abstract
OBJECTIVE: This study was conducted to evaluate fractal dimension (FD), mandibular cortical width (MCW), panoramic mandibular index (PMI), and mandibular cortical index (MCI) on panoramic radiographs to determine the mandibular cortical and trabecular bone changes in females with breast cancer undergoing aromatase inhibitors (AIs) treatment. METHODS: In this retrospective study, FD analysis, PMI, MCI, and MCW were assessed over panoramic radiographs of 34 females under AI therapy as a patient group and 34 healthy age-gender matched individuals as a control group. RESULTS: Mean FD values and MCW were slightly but not significantly lower in the patient group (1.47 ± 0.06 and 4.1 ± 1.2 respectively). FDs measured onthe supracortical area above the angulus mandibula (FD2) and anterior to the mental foramen (FD4) were significantly lower in patients (p = 0.037 and p = 0.046 respectively). Among the measured regions in patients, FD2 was significantly lower (p = 0.001). PMI was also significantly lower in patients (p = 0.001) and MCI were similar in both groups (p = 0.604). CONCLUSION: AI use affects bone quality and evaluating FD, PMI, and MCW in panoramic radiography can be used to determine the effect of this drug on the jaw bones in the early period. ADVANCES IN KNOWLEDGE: Aromatase inhibitors are the most commonly used drugs in breast cancer patients. This drug is thought to have osteoporotic effects on the jawbone. This study is the first study to evaluate osteoporotic changes with measurements made on panoramic radiographs and the results of the study are significant. We think this study will shed light on the studies that will investigate the effects of the drug on the jaw bones.

Abstract
OBJECTIVES This study compared the fractal dimension (FD) and radiomorphometric indices in the assessment of mandibular bone of patients with type 1 (T1 DM) and type 2 diabetes mellitus (T2 DM). STUDY DESIGN Panoramic radiographs of 104 patients were evaluated to calculate FD, mandibular cortical width (MCW), panoramic mandibular index (PMI), and mandibular cortical index (MCI) in the mandible. RESULTS No statistically significant differences were found in FD when T1 DM and T2 DM groups were compared with controls (P ≥ .168). Patients with T1 DM had significantly lower MCW (P < .001) and PMI (P = .030) compared with controls. Patients with T2 DM had no significant differences in MCW (P = .228) or PMI (P = .137) compared with controls. No significant differences were observed between patients with T1 DM and those with T2 DM for FD, MCW, and PMI (P > .05). In the T1 DM and T2 DM groups, there was a significant correlation between MCW and FD (P ≤ .011). No correlation was observed between FD and PMI in either the T1 DM group or the T2 DM group (P ≥ .142). No significant differences in MCI were observed between the DM groups and controls (P = .740) or between the T1 DM and T2 DM groups (P = 1.000). CONCLUSIONS The cortical and trabecular bone architectures of patients with T1 DM and T2 DM were not different. Patients with T1 DM had lower cortical measurements compared with controls.

Abstract
Osteoporosis is a severe skeletal disease that leads to bone fractures, even disability, if it remains undetected. However, osteoporosis remains frequently unnoticed until a fracture occurs. It is possible for dental practitioners to screen patients at risk of osteoporosis and refer them for an osteoporosis evaluation. Screening can be achieved mainly through dental radiographs and especially panoramic x-rays, where several radiographic indices, such as Mandibular Cortical Width (MCW), Mandibular Cortical Index (MCI), Gonial Index (GI), Antigonial Index (AI), Panoramic Mandibular Index (PMI) and alveolar crest resorption degree (M/M ratio) can be assessed. Furthermore, patients with osteoporosis develop changes in the trabecular bone of their jaws and those alternations can be detected by dentists through periapical and panoramic x-rays. Moreover, periodontitis, which is a major reason for tooth loss, deteriorates when the patient also suffers from osteoporosis. Dentists can thus screen their patients who are possibly unaware of their osteoporosis, and refer them further for dual-energy X-ray absorptiometry (DXA) examination. However, all the above indices are merely indicative of low skeletal bone mineral density and the dentist must always take into account the medical history and clinical risk factors of osteoporosis before further referring to an osteoporosis specialist.

Abstract
Purpose The goal of this study was to develop a new index as an objective reference for evaluating current and newly developed indices used for osteoporosis screening based on dental images. Its name; IDIOS, stands for Index of Dental-imaging Indices of Osteoporosis Screening. Materials and Methods A comprehensive PubMed search was conducted to retrieve studies on dental imaging-based indices for osteoporosis screening. The results of the eligible studies, along with other relevant criteria, were used to develop IDIOS, which has scores ranging from 0 (0%) to 15 (100%). The indices presented in the studies we included were then evaluated using IDIOS. Results The 104 studies that were included utilized 24, 4, and 9 indices derived from panoramic, periapical, and computed tomographic/cone-beam computed tomographic techniques, respectively. The IDIOS scores for these indices ranged from 0 (0%) to 11.75 (78.32%). Conclusion IDIOS is a valuable reference index that facilitates the evaluation of other dental imaging-based osteoporosis screening indices. Furthermore, IDIOS can be utilized to evaluate the accuracy of newly developed indices.

Abstract
OBJECTIVES The aim of the present study was to assess the feasibility of using mandibular CBCT radiomorphometric indices and box-counting fractal dimension (FD) to detect osteoporosis in post-menopausal females, compare them with the healthy control group and to correlate the findings with the bone mineral density measured by dual X-ray absorptiometry (DXA). METHODS This study consisted of 50 post-menopausal females, with age ranging from 55 to 70 years. Based on their DXA results, they were classified into osteoporotic and control groups. Mandibular CBCT radiomorphomertic indices and FD analysis were measured. RESULTS Significant differences were found for the CT cortical index scores (CTCI), CT mental index (CTMI) and CT mandibular index (CTI) between the control and osteoporotic groups. The control group showed higher mean values than the osteoporotic group. For FD values, no significant differences were found between the two groups. CONCLUSIONS CBCT radiomorphometric indices could be used as an adjuvant tool to refer patients at risk of osteoporosis for further assessment.

Abstract
BACKGROUND Osteoporosis is a disease characterized by low bone mass and microarchitectural deterioration of bone tissue, leading to bone fragility, and enhanced susceptibility to fractures. Dental radiographs, especially panoramic images, have been used to predict bone mineral density. A number of indices, (mandibular cortical index [MCI], mandibular cortical width [MCW], and panoramic mandibular index [PMI]) have been developed to assess and quantify the quality of mandibular bone mass and to observe the signs of resorption. OBJECTIVES The objectives of the study were to assess mental index (MI), MCW index, and PMI with bone density in identifying risk group for osteoporosis and also to investigate influence of age and gender on MI, MCI, and PMI. MATERIALS AND METHODS After obtaining consent, details regarding age, gender, systemic health status, and oral parafunctional habits were recorded in each patient. Then a digital panoramic radiograph was taken. The image thus obtained was subjected to calibrations and morphometric analysis using Digora version 2.7. The obtained values of indices were compared with the mean values of indices, to evaluate subjects whether they are prone to osteoporosis or not. The obtained information was subjected to statistical analysis for the significance of the parameters. RESULTS Data analysis showed that calibration indices were highly significant in the assessment of risk group for osteoporosis than noncalibration index. The subjects at a higher risk for development of osteoporosis were old-aged adults with higher prevalence being reported in women compared to male subjects. CONCLUSION In conclusion, our results suggest that higher percentage of subjects with undetected decreased bone mineral density may be identified based on trained general dental practitioners analyses of their panoramic radiographs using simple screening analytical calibration MI and MCI.

Abstract
Background : Mandibular cortical indices, like the mandibular cortical index (MCI), panoramic mandibular index (PMI), mental index (MI), antegonial index (AI) and gonial index (GI) have been developed to assess and quantify the quality of mandibular bone mass. Aim and Objectives : The aim of this pilot study was to measure the radiomorphometric indices in a digital panoramic radiograph and find the inter-relationship of the indices with age and sex of the patients. Materials and Method : A total of 23 randomly selected patients were included in the study. Panoramic radiograph of each patient was taken and radiomorphometric indices were determined. Results : There was 69.57% agreement between MI and PMI which was significant. Similarly 78.26% agreement was seen between AI and MI which was significant. In contrast 30.43%, 52.17% and 56.52% agreement was observed while comparing GI with PMI, MI and AI respectively. Conclusion : MCI, PMI, AI and MI can be effectively measured on a panoramic radiograph, hence could be used as a screening tool for determining osteoporosis. All indices have a negative correlation with age and a significant difference between the younger and older age groups. All indices were significantly lower in females when compared to males of the same age group.

Abstract
OBJECTIVES The aim of this study was to measure the mandibular cortical index (MCI), mental index (MI), panoramic mandibular index (PMI) and cortical bone thickness in the zone of the gonial angle (GT) in panoramic radiographies from a large sample of males and females and to determine how they relate to patients' age, gender and dental status. METHODS 910 panoramic radiographs were obtained and grouped into age, dental status and gender. The MCI, MI, PMI and GT were analysed. RESULTS Remarkable differences were observed for MCI and GT regarding gender, age groups and dental status on both sides (p < 0.05). While age and dental status had an effect on the MI and PMI in females, dental status had an effect on the MI and PMI in males (p < 0.05). Also, gender had an effect on the MI and PMI (p < 0.05). CONCLUSIONS The effects of age and tooth loss are different in females and males. In females, the harmful effects of tooth loss and age are more prominent according to the PMI and MI measurements. The effects of age and tooth loss in the GT and MCI measurements are similar, and these indices can be accepted as more reliable in studies including both genders.

Abstract
BACKGROUND Bone remodeling is a continuous and complex process which occurs throughout life. Radiomorphometric and radioangular indices on the orthopantomogram are the predictors of bone remodeling associated with mandible. Bone mineral density is the amount of calcified tissue in a certain volume of the bone. MATERIALS AND METHODS Fifty normal healthy individuals within the age range of 25-55 years were included in the study. Linear measurements including mandibular cortical width (MCW) and panoramic mandibular index (PMI); and angular measurements including mandibular angle (MA) and antegonial angle (AGA) were recorded. Quantitative ultrasound bone mineral density (BMD) scan of the heel bone (calcaneus) of the same patient were also performed. RESULTS In our study, for both males and females, antegonial angle (AGA) had highest correlation with calcaneus bone mineral density. In the age group of less than 35 years, PMI in males, and AGA in females had highest correlation. In the age range of more than 35 years, MA in males and AGA in females had highest correlation. CONCLUSION There is a correlation between the mandibular bone remodelling changes and calcaneal bone mineral density in case of elder subjects and thus these parameters may be used as an inexpensive alternative screening method to assess the bone mineral density and identify individuals at risk for osteoporosis and fractures and also for dental treatment planning.

Abstract
OBJECTIVE To estimate four radiomorphometric indices of mandibular bones in an 18th century population sample, and possibly associate the findings with bone mass loss related to sex, age, nutritional habits and pathologies reflecting on the bone. DESIGN Thirty-six sculls (31 males, 5 females), recovered from the crypt of Požega Cathedral in Croatia were analyzed. Age estimation was based on tooth wear, and Eichner class was determined according to the number of occlusal supporting zones. The parameters in recording analogue orthopantomographs were set to constant current of 16 mA, exposure time of 14.1s, and voltage between 62-78 kV. Films were processed in an automatic dark chamber processor for 12 min, and digitized at 8-bit, 300 dpi. The thickness of the mandibular cortex was assessed below the mental foramen (MI), at antegonion (AI), at gonion (GI). Qualitative mandibular cortical index (MCI) was assessed. RESULTS Average values of MI, AI and GI were 3.97 ± 0.94 mm, 2.98 ± 0.56 mm, and 1.99 ± 0.55 mm, respectively. Statistically significant differences between males and females were found for AI right (p=0.014), GI left (p=0.010) and GI average (p=0.006), and were in all cases higher in males. There were no statistically significant differences between age groups for either index (p>0.05). Considering Eichner classification the differences were not significant for MI (p=0.422), AI (p=0.516), and GI (p=0.443), but in Eichner classes II, MCI was significantly higher (p=0.02). CONCLUSION The obtained data does not suggest generalized malnutrition or calcium, phosphorus and vitamin D deprivation in the historic population studied.

Abstract
OBJECTIVES The aim of the present study was to evaluate the osseous changes of the jaws of patients with chronic renal failure (CRF) by CBCT. METHODS On CBCT scans obtained from 15 patients with CRF and 15 control patients (7 males and 8 females), the mean was calculated for the antegonial index (AI), mental index (MI), panoramic mandibular index (PMI) and mandibular cortical index (MCI). The MI, AI and PMI, pulp chamber size, number of teeth with pulp calcification and lamina dura loss were compared using the paired t-test, and the MCI values were analysed using the χ(2) test. RESULTS There were no statistically significant differences in the PMI, MI and AI values in patients with CRF and the control group. With regard to MCI, the cortical margins of the mandible were more porous in patients with CRF than in the control group, and also soft-tissue calcifications, lamina dura loss and radiolucent defects were more common in patients with CRF. There were no statistically significant differences in pulp chamber size and pulp calcifications between patients with CRF and the control group. CONCLUSIONS Radiographic changes in the jawbones of patients with CRF may be commonly seen. CBCT is a valuable diagnostic tool for the evaluation of osseous findings, pulp chamber, soft-tissue calcifications and MCIs and allows indices measurement in three dimensions without any superposition.

Abstract
OBJECTIVES To measure and determine mandibular cortical width (MCW) on the panoramic radiographs, to evaluate the usefulness of the method in identifying postmenopausal women with low femoral bone mineral densities (f- BMD) and to correlate the radiographic findings on panoramic radiographs with the f-BMD assessed by dual X-ray absorptiometry (DXA) to predict the efficacy of the radiographic method in diagnosing osteoporosis. MATERIALS AND METHODS One hundred and twenty postmenopausal women (60 normal and 60 osteoporotic) in the age group of 50-75 y with f-BMD assessed by DXA had undergone panoramic radiographic examination. The patients were classified as normal (T-score ≥ -1.0) and osteoporotic (T-score ≤ -2.5). MCW on panoramic radiographs was measured bilaterally at the mental foramen region with a caliper and their mean was used as the exposure measure in the analysis. RESULTS Student t-test showed that mean f-BMD, BMI and MCW was found be less in osteoporotic patients as compared to normal group with a statistically significant p-value < 0.001. Pearson correlation coefficient test revealed that MCW correlated positively with f-BMD and showed a significant decrease with age of the patient. CONCLUSION Postmenopausal women with low f-BMD had thinner mandibular cortex at the mental foramen region when compared to normal subjects and are more susceptible to femoral neck fractures. Mandibular inferior cortical width at the mental foramen region could be used to identify postmenopausal women with low f- BMD. Hence, dental panoramic radiographs serve as a useful screening tool for early diagnosis of osteoporotic fractures.

Abstract
OBJECTIVE The purpose of this study was to determine whether digital panoramic radiographs could be used for the diagnosis of osteoporosis through evaluation of the radiographs based on the correlation with bone mineral density (BMD). METHODS One hundred and ninety-four post-menopausal women were selected from participants who had participated in the Dong-gu study. Panoramic radiographic indices measured are mental index (MI), mandibular cortical index (MCI) and simple visual estimation (SVE). BMD at the lumbar spine and proximal femur was measured by dual-energy X-ray absorptiometry (DXA). The Pearson's correlation test was performed to analyse the correlation between MI and age and BMD at the lumbar spine, femoral neck and total hip. Multiple linear regression analysis was performed to analyse the association of MI, MCI and SVE with BMD after adjusting for age, height and weight. To determine the optimal cut-off point of MI for the diagnosis of osteoporosis, the receiver operating characteristic analysis was performed. RESULTS The MI was positively correlated with BMDs: lumbar spine: r = 0.36, femoral neck: r = 0.59 and total hip: r = 0.58 (p < 0.001). As age increased, MI decreased (r = -0.46). BMD at the lumbar spine and total hip were significantly lower in participants with reduction of mandibular width, thinning and resorption of mandibular cortex by the MI, SVE and MCI, respectively. The optimal cut-off value of MI for the diagnosis of spinal osteoporosis was 2.22 mm. CONCLUSION Thickness and morphological changes of mandibular inferior cortical bone are associated with BMD, independent of age, height and weight. These results suggest that MI, MCI and SVE may be useful indices for the diagnosis of osteoporosis in a Korean population.
