“… 47 In a 15-year follow-up, the best predictors of future fracture were a previous fracture and glucocorticoid medication followed by alveolar bone texture, rheumatoid arthritis, gastrointestinal disease, and secondary osteoporosis. 7 All variables, except alveolar bone texture, are identical with those identified by the large meta-analyses, on which the World Health Organization Fracture Risk Assessment Tool is based. 48 Also included in the Fracture Risk Assessment Tool are age, sex, height, weight, smoking, alcohol, and parents with fractured hip.…”

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.

“…However, it has been previously validated by objective methods, all of which are rather time consuming and not clinically useful. 30,31,47 Dentists are trained clinicians performing daily subjective assessments of caries and apical and marginal periodontitis, and in this regard the clinician remains superior to computers. The trabecular index was developed for clinicians as an easy, cost-free method of assessing bone quality before implant installation 33 and was later used for estimating osteoporosis risk 30,31,48 and risk for future fracture.…”

A further advantage of the visual index is that results are independent of all radiation parameters.…”

“…The sparse trabecular bone was observed in the 3-week, 4-week and 6-week periodontitis groups ( Figure 3) and indicated lower mandibular bone density. 3 The lowest bone density was that of the 6-week periodontitis group. This reduced mandibular bone density increased progessively during the period of the experiment ( Figure 2).…”

“…A dense mandibular alveolar trabecular pattern in a dentate subject represents a reliable indicator of normal bone mineral density, while a sparse trabecular pattern confirms low bone mineral density. 3 Chonic periodontitis has been reported as one of the risk factors relating to osteoporosis since the increasing severity of periodontitis exacerbates susceptibility to the condition. 4…”

The evaluation of mandibular bone density in chronic periodontitis models

Background: Bone density, an important factor in functional bone quality, can affect the success of implant osteointegration or orthodontic treatment. A number of studies report that chonic periodontitis constitutes one risk factor of osteoporosis characterized by low bone mineral density and that the mandible is susceptible to osteoporosis. Purpose: The purpose of this study was to evaluate mandibular bone density in animal subjects suffering from chronic periodontitis. Methods: 40 male Wistar rats were divided into four chronic periodontitis groups and four control groups (each group n=5). As chronic periodontitis models, the subjects were injected with 2×109 CFU/ml of Porphyromonas gingivalis in the sulcular gingiva, whereas control group members were injected with normal saline. After 2, 3, 4 and 6-week injection periods, the subjects were sacrificed and radiographic examination of the mandibular bone subsequently performed. Mandibular bone density was evaluated by histometric analysis. Results: The mandibular bone density in members of the chronic periodontitis group was significantly lower than those of the control group (p<0.05). The reduced mandibular bone density in the chronic periodontitis group was in line with the protracted bouts of periodontitis. Conclusion: Reduced mandibular bone density was found in the chronic periodontitis model. The longer the duration of a bout of chronic periodontitis, the greater the reduction in mandibular bone density.
