The Validity of a Smartphone-Based Method for Acquiring 3D Images of the Face.

To evaluate the accuracy and reproducibility of measurements obtained using the Bellus3D Face Application on a mobile smartphone by comparing them to direct measurements on pre-marked and blank face scans. Twenty-five healthy young adults (six males and nineteen females; age range 20-30 years) were included in this prospective cross-sectional study, with the only exclusion criterion being the presence of significant facial hair interfering with the placement and visualization of landmarks. Image acquisitions were performed using an iPhone XR with the Bellus3D FaceApp face scanning application, an iOS application for smartphones.

Headgear therapy in children with Class II malocclusion and the role of compliance on treatment outcome: A nine-month randomized controlled trial.

Objectives: To evaluate three-dimensional movements of maxillary teeth during headgear treatment in Class II growing children, using digital analytical tools, and to determine the effects of compliance on these movements.

Materials And Methods: A 9-month parallel-group randomized controlled trial was carried out on 40 children with Class II malocclusion, aged 8-12 years, half assigned to receive a cervical headgear and half to a no-treatment group, using block randomization. Subjects in the treatment group were instructed to wear the headgear for 12 hours daily and monitored using an electronic module.

How well does Invisalign ClinCheck predict actual results: A prospective study.

Introduction: This study aimed to compare achieved movements with predicted movements after 28-week use of Invisalign Lite aligners.

Teachers' report of sense of time in kindergarten predicts children's time-processing skills in first grade.

The main aim of this longitudinal study was to evaluate if a questionnaire measuring the sense of time, filled in by teachers and parents in the last year of kindergarten, was able to predict children's time-processing skills at the end of 1st grade. The sample included 131 children (initial mean age = 4.77 ± 0.

Clinical effects of different prescriptions on the inclination of maxillary and mandibular incisors by using passive self-ligating brackets.

Objective: Controlling the incisal inclination is fundamental in orthodontics. However, the relationship between the inclination prescription and its clinical outcome is not obvious, and the incisal inclination changes generated by different bracket prescriptions were investigated.

Methods: Twenty-eight non-extraction dental Class II patients (15 females, 13 males; mean age = 12.

Accuracy of planned tooth movement with lingual straight wire technique.

Objectives: To analyze the accuracy of planned tooth movements of torque, tip, rotations, and transverse width values with lingual straight-wire technique.

Materials And Methods: 40 Caucasian subjects with mean age of 23.9 years, consecutively treated in private practice with a lingual straight-wire appliance (STb, Ormco, Glendora, Calif) were evaluated.

Invisalign appliance: aesthetic and efficiency.

Background: The patients' request for treatment with clear aligners is constantly increasing. The aligners permit to the clinicians a valid way to solve a lot of orthodontic cases but the patients' compliance and the clinicians' capabilities and knowledge of the technique is fundamental for the outcome.

Methods: Seventy-two digital models of 18 consecutive patients treated with Invisalign and Smart Track aligners for 14 weeks were analyzed.

Sella Turcica Bridging and Tooth Agenesis in Children With Unilateral Cleft Lip and Palate.

Aim: To investigate differences in sella turcica size and bridging in children with unilateral cleft lip and palate (UCLP) with or without concomitant dental anomalies.

Patients And Methods: A cross-sectional study was carried out looking at 56 children with nonsyndromic UCLP. Lateral cephalograms, taken before alveolar bone grafting, were used to assess sella turcica height, width, area, and bridging.

Early versus late tracheal intubation in COVID-19 patients: a "pros/cons" debate also considering heart-lung interactions.

The best timing of orotracheal intubation and invasive ventilation in COVID-19 patients with acute respiratory distress syndrome is unknown. The use of non-invasive ventilation, a life-saving technique in many medical conditions, is debated in patients with ARDS since prolonged NIV and delayed intubation may be harmful. Shortage of intensive care beds and ventilators during a respiratory pandemic can trigger a widespread use of early non-invasive ventilation in many hospitals but which is the best way to ventilate patients with severe bilateral pneumonia and severely increased spontaneous ventilation is controversial.

Transverse and torque dental changes after passive self-ligating fixed therapy: A two-year follow-up study.

Introduction: Self-ligating appliances are purposed to expand the arches, but evidence on stability of the result is lacking. We measured the width of maxillary and mandibular arches and torque changes after treatment with the use of passive self-ligating appliances and assessed stability at the 2-year follow-up.

Methods: Maxillary and mandibular 3-dimensional (3D) models from 32 subjects (mean initial age 14.

Geometric morphometric analysis of the palatal morphology in children with impacted incisors: A three-dimensional evaluation.

Objective: To analyze variations in palatal morphology in subjects presenting unilaterally impacted maxillary permanent central incisors compared with a control group of subjects without eruption anomalies using a three-dimensional (3D) analysis.

Materials And Methods: Twenty-six white subjects (10 girls and 16 boys; mean age 9.5 ± 1.

Rapid palatal expansion effects on mandibular transverse dimensions in unilateral posterior crossbite patients: a three-dimensional digital imaging study.

Background: The purpose of this controlled study was to investigate indirect effects on mandibular arch dimensions, 1 year after rapid palatal expansion (RPE) therapy.

Methods: Thirty-three patients in mixed dentition (mean age 8.8 years) showing unilateral posterior crossbite and maxillary deficiency were treated with a RPE (Haas type) cemented on the first permanent molars.

Efficacy and effects of palifermin for the treatment of oral mucositis in patients affected by acute lymphoblastic leukemia.

This randomized-controlled trial studied the efficacy of palifermin, administered as a dose during hematopoietic stem cell transplant (HSCT) therapy, as primary prophylaxis on pediatric patients with acute lymphoblastic leukemia in order to reduce oral mucositis (OM). Patients in the palifermin group were randomly assigned to receive palifermin, 60 μg/kg, intravenously as a single dose 3 days before and 0, +1, and +2 post autologous HSCT infusion. The patients in the control group received only a placebo treatment.

Postoperative Analgesia after Laparoscopic Ovarian Cyst Resection: Double-blind Multicenter Randomized Control Trial Comparing Intraperitoneal Nebulization and Peritoneal Instillation of Ropivacaine.

Study Objective: To compare the effects of local anesthetic intraperitoneal nebulization with intraperitoneal instillation during laparoscopic ovarian cystectomy on postoperative morphine consumption and pain.

Design: Multicenter, randomized, case-control trial.

Dental arch response to Haas-type rapid maxillary expansion anchored to deciduous vs permanent molars: A multicentric randomized controlled trial.

Objective: To assess maxilla and mandibular arch widths' response to Haas-type rapid maxillary expansion (RME) anchored to deciduous vs permanent molars on children with unilateral posterior crossbite.

Materials And Methods: Seventy patients with unilateral posterior crossbite recruited at the Universities of Genova, Siena, and Insubria (Varese) were randomly located into GrE (RME on second deciduous molars) or Gr6 (RME on first permanent molars) and compared.

Results: Upper intermolar distance and permanent molar angulation increased significantly in Gr6 vs GrE at T1.

Dentoalveolar class III treatment using retromolar miniscrew anchorage.

In this article, we report the successful use of miniscrews in the distalization of the lower dentition to correct an Angle class III malocclusion with lower anterior crowding in a dolichofacial adult patient. Conventional intraoral and extraoral appliances have many disadvantages, including the need for patient cooperation, potential for anchorage loss, and vertical extrusion of upper molars and lower incisors. Extrusion should be prevented or minimized when treating long-faced patients with reduced overbite.
