Evaluating mandibular symphysis bone density according to various skeletal patterns with CBCT

Objective The aim of this retrospective study was to evaluate the bone density (BD) at the mandibular symphysis according to horizontal and vertical patterns using cone‐beam computed tomography (CBCT). Setting and Sampling Three hundred nineteen untreated adults with a mean age of 24 years. Material...

description Objective The aim of this retrospective study was to evaluate the bone density (BD) at the mandibular symphysis according to horizontal and vertical patterns using cone‐beam computed tomography (CBCT). Setting and Sampling Three hundred nineteen untreated adults with a mean age of 24 years. Materials and Methods CBCT images were converted into the lateral cephalometric images, and tracings were performed for categorizing the patients based on skeletal features. Cortical BDs at B point, pogonion (Pog), genion (Ge) and menton (Me), and cancellous BDs of the mandibular symphysis were measured using CBCT images. Statistical analyses were performed to evaluate the effects of horizontal and vertical skeletal patterns on BDs. Results Females exhibited higher BD than males at the Me, Pog, Ge (P

Normovergent skeletal pattern showed significantly higher cortical BD than hypodivergent skeletal patterns at Me (P = .001). Class II skeletal pattern showed significantly higher cortical BD than Class I and III skeletal patterns at Me (P &lt; .001) and Ge (P &lt; .05). Class I skeletal pattern showed significantly higher mean cortical BD than Class III skeletal pattern at B point (P = .025). Cancellous BD was higher in Class III and hypodivergent skeletal patterns than others but showed no statistical significance. Conclusions Significant differences were identified across various skeletal patterns. Several mandibular symphyseal landmarks showed statistically significant differences in BD at Me, B point and Ge, with Me having the most statistically significant findings.</description><identifier>ISSN: 1601-6335</identifier><identifier>EISSN: 1601-6343</identifier><identifier>DOI: 10.1111/ocr.12405</identifier><identifier>PMID: 32599658</identifier><language>eng</language><publisher>England: Wiley Subscription Services, Inc</publisher><subject>Adult ; adults ; Bone Density ; CBCT ; Cephalometry ; Computed tomography ; Cone-Beam Computed Tomography ; Dentistry ; Female ; Humans ; Male ; Mandible ; Mandible - diagnostic imaging ; mandibular symphysis ; Retrospective Studies ; skeletal patterns ; Spiral Cone-Beam Computed Tomography ; Statistical analysis ; Young Adult</subject><ispartof>Orthodontics &amp; craniofacial research, 2021-02, Vol.24 (1), p.70-77</ispartof><rights>2020 John Wiley &amp; Sons A/S.
