013) and the chin (P=0.013) when considering the root mean square values. selleck chemicals llc In addition, 3D centroid differences were found in the transverse and sagittal direction of the right ramus (P=0.034 and P=0.005, respectively) and the sagittal aspect of the left ramus (P=0.025). Considering 2mm as a threshold of clinical relevance, almost all the bone fragments (maxilla, proximal, and distal mandibular segments) were accurately corrected by surgery, although not in the chin.

On the basis of the obtained values, it is possible to consider the Dolphin Imaging software as clinically acceptable for performing virtual orthognathic surgical planning.

Children with attention deficit hyperactivity disorder (ADHD) have more sleep breathing problems and parafunctional oral habits than individuals without ADHD. However, there is scarce information on the correlation between their dental malocclusion and these functional disorders. The objective of this study was to assess the severity of malocclusion in patients with and without ADHD and to evaluate the correlation between their functional disorders and dental malocclusion.

Eighty-eight patients aged 6-17years were divided into 2 groups ADHD (n=44) and control (n=44). A medical questionnaire to assess functional disorders and an orthodontic examination to evaluate malocclusion were completed for each patient. Distribution of the data was evaluated using Shapiro-Wilk test, whereas the 2 groups were compared with a t test, Mann-Whitney U test, Fisher exact test, and Spearman correlation. The association between parafunctional oral habits, ADHD drug intake, and malocclusion severity were assessed with a t test and Mann-Whitney U test.

Patients with ADHD had significantly higher severity of malocclusion (P=0.042), more dental rotation (P=0.021) and more parafunctional oral habits (P=0.001), specifically bruxism (P=0.005), and a history of pacifier use (P=0.009), than the control group.

It is important to be aware of the increased risk of parafunctional oral habits and dental malocclusion among ADHD patients to develop preventive programs, as well as therapeutic strategies for them.

White spot lesions are a common side effect of orthodontic treatment. This laboratory study aimed to explore the suitability of chlorhexidine hexametaphosphate (CHX-HMP) as a coating for orthodontic elastomeric ligatures to provide sustained chlorhexidine (CHX) release.

Dissolution kinetics of CHX-HMP were firstly explored using spectroscopy and a colorimetric phosphate assay. Elastomeric ligatures were categorized into 3 groups-acetone-conditioned, ethanol-conditioned, and as received-and were then immersed in 5mM CHX-HMP suspension or 5mM chlorhexidine digluconate solution and rinsed. CHX release was measured over 8weeks, and the effects of conditioning and immersion on elastomeric force and extension at rupture and surface topography were investigated.

CHX-HMP exhibited a gradual equilibration that had not reached equilibrium within 8weeks, releasing soluble CHX and a mixture of polyphosphate and orthophosphate. CHX digluconate-treated ligatures showed no CHX release, whereas CHX-HMP-treated ligatures showed varying degrees of release. As received, CHX-HMP-treated ligatures showed a modest release of CHX up to 7days. Acetone conditioning did not enhance CHX-HMP uptake or subsequent CHX release and caused a deterioration in mechanical properties. Ethanol conditioning enhanced CHX-HMP uptake (6×) and led to a sustained CHX release over 8weeks without affecting mechanical properties.

Within the inherent limitations of this in-vitro study, CHX-HMP led to a sustained release of CHX from orthodontic elastomeric ligatures after ethanol conditioning. Conditioned and coated elastomeric ligatures may ultimately find application in the prevention of white spot lesions in orthodontic patients.

The treatment included bilateral extraction of the maxillary first premolars, accurate 3-digital setup, a 2-stage torque control strategy, and intricate mechanic management. The dilemma of tooth-size discrepancy was solved by ideal torque control to avoid interproximal enamel reduction. An ideal Class I molar and canine relation, as well as canine guidance in the lateral excursion movement, was achieved with good stability.
During the decision-making process, physicians rely on heuristics that consist of simple, useful procedures for solving problems, intuitive shortcuts that produce reliable decisions based on limited information. In clinical situations characterized by a high degree of uncertainty such as thoseencountered in orthodontics, cognitive biases and judgment errors related to heuristics are not uncommon. This study aimed at promoting trust in the effective interface between the intuitive reasoning of the orthodontic practitioner and the computational heuristics emerging from simple statistical models.

We propose an integrative model based on the interaction between clinical reasoning and 2 computational tools, cluster analysis and fast-and-frugal trees, to extract a structured craniofacial representation of untreated subjects with Class III malocclusion and to forecast the worsening of the malocclusion over time.

Cluster analysis of cephalometric values from 144 growing subjects with Class III malocclusion followed longitudinally (T1 mean age, 10.
