Dataset Information

Datasets describing the morphometric evaluation of the adult rat mandible following growth stimulation of the condyle using ultrasound.

ABSTRACT: Evaluating morphological changes of the mandible due to the unique role of the condyle in mandibular special growth and remodeling pattern is challenging. This data describes a comprehensive evaluation using new techniques to detect morphological changes of the young adult rat mandibles treated by low intensity pulsed ultrasound (LIPUS) comparing to matching controls. Two-dimensional (2D) analysis was performed on digital photographs of the hemi-mandibles using AutoCAD software with high accuracy. The anatomical points which were more determinative and prone to visual illusion were defined with particularity. Selective combination of measurements was done to allow for a thorough morphometric evaluation of the mandible focusing on the condyle and the main direction of condylar and mandibular growth. The procedure was simulated for three-dimensional analysis of virtual models of the hemi-mandibles via Geomagic-Qualify software. In the whole procedures, conditions were strictly standardized to ensure reliability and repeatability. Further Insights, Interpretations and discussions of the present datasets can be find in https://doi.org/10.1016/j.bonr.2021.101122[1].

Project description:To analyze the morphology of paired fibula and mandible aiming to choose optimal fibular segments for mandibular reconstruction in a Chinses population. A total of 118 cases of paired mandible and fibula was collected. All patients were received preoperative cone beam CT (CBCT) scans for mandibular evaluation and CT-angiographical (CTA) examination of the bilateral lower legs, respectively. The cross-sectional morphological differences between proximal (Side P), middle (Side M) and distal (Side D) segments of fibula and anterior, premolar and molar areas of mandible were compared. The most frequent cross-sectional shape at Side D, Side M and Side P portion of fibula was circular (75.4%), triangular (67.8%) and circular (49.2%), respectively. In anterior, premolar and molar areas of mandible, the most of the cross-section was s-shape (90.82%), straight (83.64%) and oblique (91.89%), respectively. The height and width of upper one third (W1) at Side M were significantly larger than those of Side D and Side P (p < 0.0001). There was significantly difference of width of lower one third (W2) among three groups (p < 0.0001). As for the height and widths of mandible, there was significant difference among anterior, premolar and molar regions (p < 0.0001). The rate of height between Side M of fibula and mandible (H (Side M/area)) was significantly larger than H (Side D/area) and H (Side P/area) (p < 0.01). The ratio of W1 between Side D of fibula and mandible (W1 (Side D/area)) was significantly larger than that of W1 (Side M/area) and W1 (side P/area) (p < 0.05). As for the ratio of W2 between fibula and mandible (W2 (plane/area)), there was significant difference among groups (p < 0.01). The distal and middle segments of fibula were suitable for reconstructing the anterior area of mandible and the proximal segment of fibula was more compatible with the premolar and molar areas of mandible.Clinical Relevance Presurgical morphometric analysis of paired fibula and mandible aids for optimal fibular-based mandibular reconstruction.
