The effect of reduced BMD on the jawbones is still not fully understood. The purpose of the study was to evaluate the impact of BMD on the quality and quantity of the edentulous mandible. Methods: The present study included 127 edentulous postmenopausal women who underwent cone beam computed tomography (CBCT) examinations. BMD measurements of the lumbar spine and femoral necks were performed by dual-energy X-ray absorptiometry. In the cross-sectional CBCT images, three different areas of the mandible (lateral incisor, first premolar, and first molar) were selected. The complete mandibular, trabecular, and cortical bone volumes were measured. All measurements were performed on the total mandibular area, and the basal and alveolar parts of the mandible. Results: The volume of the cortical bone was reduced for females with reduced BMD in the lateral incisor and first premolar regions, both in the total mandibular area and in the basal part of the mandible. The trabecular bone volume statistically significantly increased when the BMD decreased in the complete mandibular area and the basal part of the mandible (linear regression). The total bone volume significantly decreased with a decrease in BMD in the basal part of the mandible. Conclusions: Reduced BMD has a negative effect on the quantity and quality of bone in the basal part of the edentulous mandible.<\/jats:p>","DOI":"10.3390\/dj11010017","type":"journal-article","created":{"date-parts":[[2023,1,4]],"date-time":"2023-01-04T01:42:44Z","timestamp":1672796564000},"page":"17","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["The Effect of General Bone Mineral Density on the Quantity and Quality of the Edentulous Mandible: A Cross-Sectional Clinical Study"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8353-4187","authenticated-orcid":false,"given":"Anda","family":"Slaidina","sequence":"first","affiliation":[{"name":"Department of Prosthodontics, Riga Stradins University, LV-1083 Riga, Latvia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Baiba","family":"Springe","sequence":"additional","affiliation":[{"name":"Department of Prosthodontics, Riga Stradins University, LV-1083 Riga, Latvia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andris","family":"Abeltins","sequence":"additional","affiliation":[{"name":"Department of Orthodontics, Riga Stradins University, LV-1083 Riga, Latvia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0684-2025","authenticated-orcid":false,"given":"Sergio E.","family":"Uribe","sequence":"additional","affiliation":[{"name":"Department of Conservative Dentistry and Oral Health, LV-1083 Riga, Latvia"},{"name":"Baltic Biomaterials Centre of Excellence, Headquarters at Riga Technical University, LV-1083 Riga, Latvia"},{"name":"School of Dentistry, Universidad Austral de Chile, Valdivia 5110566, Chile"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aivars","family":"Lejnieks","sequence":"additional","affiliation":[{"name":"Clinics \u201cGailezers\u201d, Riga East Clinical University Hospital, LV-1079 Riga, Latvia"},{"name":"Department of Internal Diseases, Riga Stradins University, LV-1083 Riga, Latvia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,1,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"266","DOI":"10.1016\/0022-3913(71)90069-2","article-title":"Reduction of residual ridges: A major oral disease entity","volume":"26","author":"Atwood","year":"1971","journal-title":"J.
