Osteoporosis and jawbones in women.

Gulsahi A - J Int Soc Prev Community Dent (2015 Jul-Aug)

Bottom Line: Mandibular cortical bone undergoes resorptive activity in osteoporotic patients, leading to a decreased thickness and more porous inferior border.Therefore, studies have demonstrated the usefulness of cortical width and shape, determined from panoramic radiographs, in identifying elderly individuals with undetected osteoporosis, especially postmenopausal women.In conclusion, postmenopausal women with C3 category, Mental Index (MI) <3 mm, and panoramic mandibular index (PMI) <0.3 may be considered for further osteoporosis investigation.

ABSTRACT
Osteoporosis is a major health problem affecting one in three women over the age of 50 and may not be detected until fractures occur. Since osteoporotic fractures are a health burden worldwide, identifying subjects with a high risk of osteoporosis and preventing osteoporosis-related mortality and morbidity are a very important health strategy. Women show an estrogen-related bone loss starting at menopause, predominantly occurring in trabecular bone. Diagnosis of osteoporosis is usually based on the bone mineral density measurement, but this is not a practical and economical technique for early detection. Therefore, investigators are interested in the possibility of detecting osteoporosis from the panoramic radiographs. Mandibular cortical bone undergoes resorptive activity in osteoporotic patients, leading to a decreased thickness and more porous inferior border. Therefore, studies have demonstrated the usefulness of cortical width and shape, determined from panoramic radiographs, in identifying elderly individuals with undetected osteoporosis, especially postmenopausal women. In conclusion, postmenopausal women with C3 category, Mental Index (MI) <3 mm, and panoramic mandibular index (PMI) <0.3 may be considered for further osteoporosis investigation.

Figure 3: C3 category of MCI

Mentions: MCI or KI refers to the appearance of the inferior cortex of the mandible and is classified as follows: C1: the endosteal margin of the cortex is even and sharp on both sides [Figure 1]; C2: The endosteal margin presents semilunar defects (lacunar resorption) and/or appears to form endosteal cortical residues on one or both sides [Figure 2]; and C3: The cortical layer forms heavy endosteal cortical residues and is clearly porous [Figure 3].[17] Some studies have reported that women with a mild to moderate and severe eroded cortex are considered to have an increased likelihood of osteoporosis.[111181920] However, others indicated no usefulness of the MCI.[82122] A recent study showed that approximately 95% of Japanese women identified by trained dentists using cortical shape findings did have osteopenia or osteoporosis.[14] As a result, studies concluded that the sensitivity of MCI in the diagnosis of osteoporosis (T-score <−2.5) varied from 35.9 to 90.9%.[16818192123242526] The differences among the results is considered to be due to the heterogeneity of the studies.[23]
