Article Synopsis
  • The study investigates the changes in position of impacted third molars (M3) during treatment for Class II malocclusion, particularly in cases where four first premolars are extracted.
  • Researchers analyzed pre- and post-treatment dental images of 30 patients who underwent orthodontic treatment, focusing on the relationship between teeth positioning and changes in M3 space.
  • Findings showed improved angulation and increased space for the lower M3s, suggesting that the surgical extraction of impacted third molars may not always be necessary in certain orthodontic treatments.

Background: This study compared the effectiveness of the traditional and revised one-bag protocols for pediatric diabetic ketoacidosis (DKA) management.

Methods: This single-center retrospective cohort study included children diagnosed with DKA upon admission between 2012 and 2019. Our institution reevaluated and streamlined the traditional one-bag protocol (revised one-bag protocol).

Examining the extent to which sex differences in three-dimensional (3D) facial soft tissue configurations are similar across diverse populations could suggest the source of the indirect evolutionary benefits of facial sexual dimorphism traits. To explore this idea, we selected two geographically distinct populations. Three-dimensional model faces were derived from 272 Turkish and Japanese men and women; their facial morphologies were evaluated using landmark and surface-based analyses.

The soft-shell clam is one of the most ancient invaders of European coasts and is present in many coastal ecosystems, yet little is known about its genetic structure in Europe. We collected 266 samples spanning a latitudinal cline from the Mediterranean to the North Sea and genotyped them at 12 microsatellite loci. In parallel, geometric morphometric analysis of shell outlines was used to test for associations between shell shape, latitude and genotype, and for a selection of shells we measured the thickness and organic content of the granular prismatic (PR), the crossed-lamellar (CL) and the complex crossed-lamellar (CCL) layers.

Surgically assisted rapid mandibular expansion is a contemporary treatment alternative to enable genuine skeletal mandibular widening. Mandibular widening via a tooth-borne distractor is a practical and noninvasive clinical approach. Recently, to expand and protract the maxilla, the alternate rapid maxillary expansion-and-constriction procedure was suggested.

Objective: To test the null hypothesis that children with Class I, II, and III malocclusions who have not undergone orthodontic therapy present with displaced discs.

Materials And Methods: This study relied on retrospective material consisting of 76 unilateral left sagittal-oblique temporomandibular joint (TMJ) magnetic resonance imaging (MRIs) and lateral cephalometric radiographs taken in maximum intercuspal position in patients with clinically symptom-free and orthodontically untreated Class I (n = 30; 19 girls and 11 boys), Class II (n = 26; 10 girls and 16 boys), and Class III malocclusion (n = 20; 5 girls and 15 boys). The mean ages of patients with Class I, II, and III malocclusions were 10.

The purpose of this study was to evaluate the changes in the airway space after surgical correction of Class III skeletal dentofacial deformity and to determine if orthognathic surgery alters the airway space and improves obstructive sleep apnea. Twenty-four Class III adults treated with orthognathic surgery were divided into two groups as Mandibular set-back (Bilateral Sagittal Split Osteotomy-BSSO, 10 patients) and two jaw surgery (Bilateral Sagittal Split Osteotomy combined with Le Fort I maxillary advancement, 14 patients). Lateral cephalometric radiographs were traced before (T0) and 6 months after surgery (T1).

Article Synopsis
  • - The study aimed to compare the effectiveness of late orthopedic therapy using a modified maxillary protraction appliance (MMPA) versus orthognathic surgery (bimaxillary surgery or BMS) in treating skeletal class III cases.
  • - Two groups were analyzed: one with younger patients (mean age 14.5) treated with MMPA and the other with older patients (mean age 23) undergoing BMS, with various measurements taken before and after treatment.
  • - Results showed that BMS led to greater maxillary advancement and specific improvements in the soft tissue profile compared to MMPA, suggesting that surgery may be more effective for certain skeletal features, particularly in longer and more anteriorly positioned mandibles.

The aim of this case report was to evaluate the effect of symphyseal distraction osteogenesis on the position of the mandibular condyle and the disc of an asymptomatic adolescent patient by using magnetic resonance imaging and computerized tomography. A 15-year-old girl with severe maxillary and mandibular dental crowding was treated with a Haas-type banded maxillary expansion appliance and symphyseal distraction osteogenesis with a Hyrax-type tooth-borne distractor, respectively. Lateral cephalometric and panoramic radiographs, dental casts, and extraoral and intraoral photographs were obtained before and after treatment in addition to temporomandibular joint magnetic resonance imaging and computerized tomography scans.

This study was conducted on lateral cephalograms and magnetic resonance images (MRIs) obtained from 20 subjects with Class III malocclusion. Only clinically temporomandibular joint (TMJ) symptom-free subjects were included in this study. In the treatment group, a chin cup with 600 g of force was applied in 13 patients (10 girls and three boys) with a mean age of nine years.

There are many criteria and methods used to constitute and determine a standardized esthetic concept in orthodontics. However, the subjectivity of the esthetic concept is the common opinion of the authors. Ethnic and racial differences play a major role in diversifying esthetic preferences.

Article Synopsis
  • * Among 32 treated patients, 25% showed signs or symptoms of TMD, while 23% in the untreated Class III group and 41.5% in the normal occlusion group presented symptoms, indicating that chin-cap treatment does not significantly increase TMD risk.
  • * The findings suggest that chin-cap therapy is not a predictor or protector against TMD, emphasizing the importance of considering age and stress factors in TMD evaluations.

The aim of this study was to clarify disk position relative to the condyle and condylar position relative to the glenoid fossa in clinically asymptomatic and orthodontically untreated young adult Class III patients by magnetic resonance imaging (MRI). In addition, the relationship between skeletal Class III morphology and positional changes of the temporomandibular joint (TMJ) components were investigated. The material consisted of 34 bilateral sagittal oblique TMJ MR images (MRIs) and lateral cephalometric radiographs taken in a closed mouth position.

The purpose of this study was to evaluate bone activity at the midpalatal suture that had been biomechanically stimulated by rapid maxillary expansion (RME). A rigid acrylic-bonded expansion device with a maxiskeleton screw was used for RME in three patients who were in three different growth periods. The screw was activated twice a day by 1/4 turns.
