“…In a new report, the group with sparse trabeculation had more skeletal bone loss, lower BMD, and larger marginal bone level decrease after 5 years than those with not-sparse trabeculation, but surprisingly the little group with dense trabeculation experienced both the greatest 5-year skeletal bone loss and marginal bone level decrease. 92 The reason may be that dense trabeculation implies the greatest trabecular endosteal bone surface, and consequently the largest number of bone cells and remodeling sites. Negative events may lead to the most negative responses in dense trabecular bone but research is warranted to clarify whether dense trabeculation leads to the best results after appropriate treatment?…”

Maxillary and mandibular bone mirror skeletal bone conditions. Bone remodeling happens at endosteal surfaces where the osteoclasts and osteoblasts are situated. More surfaces means more cells and remodeling. The bone turnover rate in the mandibular alveolar process is probably the fastest in the body; thus, the first signs of osteoporosis may be revealed here. Hormones, osteoporosis, and aging influence the alveolar process and the skeletal bones similarly, but differences in loading between loaded, half-loaded, and unloaded bones are important to consider. Bone mass is redistributed from one location to another where strength is needed. A sparse trabeculation in the mandibular premolar region (large intertrabecular spaces and thin trabeculae) is a reliable sign of osteopenia and a high skeletal fracture risk. Having dense trabeculation (small intertrabecular spaces and well-mineralized trabeculae) is generally advantageous to the individual because of the low fracture risk, but may imply some problems for the clinician.

AimRapid and straightforward screening for osteoporosis is essential. Studies have indicated a significant correlation between systemic and alveolar bone mineral density (al‐BMD). Therefore, dental radiographs, which are commonly used in dental treatments, can potentially be used to screen for osteoporosis through al‐BMD. This study evaluated the al‐BMD of teeth designated for extraction from patients receiving bisphosphonates (BPs) using DentalSCOPE®, a novel al‐BMD measurement device, and conducted preliminary analyses for future al‐BMD research.Materials and methodsThe al‐BMD of 54 female osteoporosis patients treated with BPs and 90 teeth were measured using DentalSCOPE®. Twelve healthy female adults without any dental diseases were included as controls. We analyzed the al‐BMD characteristics of each tooth type and the relationship between al‐BMD and the development of medication‐related osteonecrosis of the jaw (MRONJ) post‐extraction. Furthermore, we compared al‐BMD with that of healthy controls and examined the impact of periodontal disease on al‐BMD.ResultsSignificant variations in the al‐BMD were observed among tooth types, with higher densities in the mandibular molars than in the premolars. Additionally, the premolar and molar densities were significantly higher than those of the maxilla. No MRONJ cases were reported during the 2‐year follow‐up period after tooth extraction. The al‐BMD values were similar between healthy adults and patients with osteoporosis. Although the al‐BMD was lower in teeth affected by periodontitis, this difference was not statistically significant.ConclusionThis study revealed differences in al‐BMD among tooth types. Since al‐BMD reflects anatomical and other factors beyond actual bone mineral density, further research is needed to elucidate its association with osteoporosis and MRONJ.
