The Use of the Panoramic Mandibular Index in Analyzing Cortical Mandibula Height in Batak Tribe Women With Perimenopause and Postmenopause Conditions

ancellous and cortical bone loss in postmenopausal women can be caused by a lack of estrogen, which plays an important role in growth and maturation. The panoramic mandibular index (PMI) also detects loss of bone mass and is a reference for individuals at high risk of developing osteoporosis. Therefore, this study aimed to determine the PMI value in Batak women with postmenopausal conditions using a descriptive survey correlation cross-sectional method. The samples were panoramic radiographs of Batak women with postmenopausal conditions aged >52 years and premenopausal as controls. Furthermore, the data was tested using an Unpaired T-test and the average PMI values in the premenopausal and postmenopausal Batak women groups were 0.327 ± 0.058 and 0.296 ± 0.063, respectively. Statistical analysis indicated a significant difference (p < 0.05, specifically 0.027) in PMI values between the premenopausal and postmenopausal Batak women. These findings showed that PMI served as a reliable indicator of bone loss and potentially aid in identifying individuals at a higher risk of developing osteoporosis.
