Purpose: To determine the height and volume of the mandibular coronoid process (CP) by cone-beam computed tomography (CBCT) and to identify the presence of any correlations of these measurements with age, gender, facial type, and skeletal class.
Materials And Methods: The sample consisted of 132 patients from a departmental routine patient base. After CBCT, CP height was determined using OnDemand 3D software (CyberMed, Seoul, Republic of Korea), and CP volume was obtained using ITK-SNAP 3.0 software (Cognitica, Philadelphia, PA). Measurements were subjected to analysis of covariance against facial type, skeletal class, gender, and age, with a significance level of 5%.
Results: CP height and volume were similar regardless of age, facial type, and skeletal class. However, the 2 measurements were statistically different regarding gender, with larger values for men than for women.
Conclusions: These observations suggest that gender is the only factor influencing the height and volume of the CP.

Introduction: This study aimed to assess the root resorption and alveolar bone changes of maxillary incisors volumetrically and 3-dimensionally in patients with Class II Division 1 malocclusion who underwent treatments involving the extraction of 4 first premolars with conventional fixed appliances (FAs) vs clear aligners (CAs).
Methods: A total of 320 maxillary incisors from 80 patients were assessed and divided into 2 groups (FAs and CAs), each possessing similar baseline characteristics. Pretreatment and posttreatment cone-beam computed tomography scans were used to analyze linear and volumetric orthodontically induced inflammatory root resorption, alveolar bone thickness (ABT), alveolar bone height (ABH), as well as anteroposterior and vertical movements of maxillary incisors.

: Sinus lifting, a procedure to augment bone in the maxilla, may cause complications such as sinusitis due to impaired drainage. This study aimed to assess how sinus lifting impacts airflow in the sinus cavity, which is essential for patients undergoing dental implants. Using computational fluid dynamics (CFD), this research analyzed airflow changes after sinus floor elevation, offering insights into the aerodynamic consequences of the procedure.

It is known that the pituitary gland volume (PV) in idiopathic central precocious puberty (IPP) is significantly higher than in healthy children. However, most PV measurements rely on manual quantitative methods, which are time-consuming and labor-intensive. This study aimed to automatically measure the PV of patients with IPP using artificial intelligence to accurately quantify the correlation between IPP and PV, and to improve the efficiency of diagnosing IPP.

Simulating the cardiac valves is one of the most complex tasks in cardiovascular modeling. As fluid-structure interaction simulations are highly computationally demanding, machine-learning techniques can be considered a good alternative. Nevertheless, it is necessary to design many aortic valve geometries to generate a training set.
