The present study aimed to assess the skeletal and dental ages of type 1 diabetes mellitus (T1DM) patients. Therefore, panoramic and hand-wrist radiographs of 82 patients, aged between 5 and 15 years, were collected and divided into case and control groups. The case group consisted of 41 panoramic and 41 hand-wrist radiographs of T1DM patients, whereas the control group consisted of 41 panoramic and 41 hand-wrist radiographs of patients without T1DM. Skeletal age was assessed according to the method of Greulich and Pyle (1999), whereas dental age was assessed according to the method of Nolla (1960). Chi-square tests revealed no statistically significant differences between skeletal and dental ages between the case and control groups (p > 0.05). However, in the case group, the skeletal age of females was greater than that of age-matched males (p = 0.005). Considering that skeletal and dental growth of the case and control groups were closely related, clinical interventions involving orthodontics and dentomaxillofacial orthopedics should be equally performed both for healthy and specific patient groups, such as those with T1DM.

Background: Orthodontic treatment involves manipulation of tooth position that can temporarily lead to occlusal interferences capable of inducing bruxism. The objectives of this study were to determine the self-reported incidence of bruxism and its association with factors such as facial type, divergence, skeletal and dental malocclusions in orthodontic patients.
Materials And Methods: 80 patients who underwent a minimum of six months of orthodontic treatment were surveyed using a validated self-reported bruxism questionnaire for the presence or absence of bruxism.

Background: Maxillary canine impaction can result in malocclusion, temporomandibular joint complications, and esthetic concerns, thus influencing craniofacial development. Although cases of impacted canines are not uncommon in clinical practice, the likelihood of simultaneous bilateral impaction is extremely low; very few reports have documented cases of bilaterally symmetrical, inversely impacted canines.
Case Presentation: This paper reports a rare case of maxillary canine impaction, a condition characterized by the abnormal eruption of teeth.

Introduction: The dentoskeletal effects of clear aligner treatment (CAT) with Invisalign vs temporary skeletal anchorage device-anchored Sydney intrusion spring (SIS) were compared in consecutively treated growing patients with anterior open bite using cone-beam computed tomography scans.
Methods: Fifteen adolescents treated exclusively with Invisalign, and 14 with SIS (first-phase treatment) were assessed retrospectively. Rigid-wise, voxel-based registration of pretreatment and posttreatment cone-beam computed tomography scans were performed using the anterior cranial base, maxillary plane, and mandibular body as reference regions.

As maxillofacial surgery becomes increasingly digitized and the transformative impact of pre-surgical scanning and computer simulation is recognized, this clinical paper presents an algorithm for the selection of interventions in severe congenital oligodontia with Angle class-III malocclusion (OCIII) utilizing such technologies. A complex, multifactorial condition with varying degrees of craniofacial involvement, OCIII is associated with edentulous facial appearance, mandibular prognathism and deep underbite, as well as malocclusion. Our methodology involves the integration of CBCT imaging, intra- and extra- oral scanning, and 3D planning with the assessment of bone volume, number of missing teeth, skeletal discrepancies, and patient compliance in the selection of suitable treatments.

Introduction: Age estimation is crucial in forensic and anthropological fields. Teeth, are valued for their resilience to environmental factors and their preservation over time, making them essential for age estimation when other skeletal remains deteriorate. Recently, Machine Learning algorithms have been used in age estimation, demonstrating high levels of accuracy.
