OBJECTIVES: To introduce a new, fast, reliable, and free from software-related bias method to predict three-dimensionally the root position and angulation during and after orthodontic treatment. The final goal is to keep to a minimum the use of ionizing radiation by eliminating the necessity of multiple radiation exposure for checking root alignment.

OBJECTIVE: To correlate traditional Steiner's skeletal and dental measurements to similar measurements that use the eyes and natural head position as references instead of the cranial base. SETTING AND SAMPLE: One hundred and fifty-two lateral cephalometric radiographs (66 female, and 86 male) from the Harvard Forsyth twin sample were included in the study based on record availability. MATERIAL AND METHODS: This was an observational study in which all cephalometric radiographs were traced and analyzed using Steiner's cephalometric analysis...

The aim was to assess the influence of corticosteroid therapy (CST) on orthodontic tooth movement (OTM). A narrative review of studies performed in animal models. Indexed databases were searched up to and including May 2018 to address the following focused question: "Does CST affect OTM?" The following eligibility criteria were imposed: (a) original studies; (b) presence of a control group (OTM without CST); (c) intervention: effect of CST on OTM; and (d) statistical analysis. Quality assessment was performed using the Animal Research Reporting In Vivo Experiment (ARRIVE) guidelines...

OBJECTIVE: To investigate the association of single nucleotide variants in the candidate genes WNT10A, WNT10B and GREM2 with isolated tooth agenesis. SETTING AND SAMPLE POPULATION: A total of 435 Caucasian individuals (88 cases with isolated tooth agenesis and 347 unrelated controls) were ascertained at the University of Texas Health Science Center at Houston School of Dentistry. Clinical and radiographic examination by orthodontists confirmed the diagnosis of tooth agenesis...

OBJECTS: Rapid palatal expansion (RPE) is a widespread orthopaedic procedure used in several clinical situations. The aim of the study was to provide a systematic review and meta-analysis of transverse intercanine and intermolar width changes after RPE and long-term effects. SETTING AND SAMPLE POPULATION: A systematic literature search was conducted until January 2018 on original studies with RPE treatment. MATERIAL AND METHODS: Intercanine and intermolar distance were measured at the start of RPE (T1, median age 9...

OBJECTIVES: The aim was to review the literature regarding genetic contributions to temporomandibular joint disorder (TMD) after our 2008 publication. SETTING AND SAMPLE POPULATION: Literature review. MATERIAL AND METHODS: PubMed and MEDLINE were used to obtain literature in any language regarding genes and TMD, using the keywords "temporomandibular joint disorder" and "temporomandibular joint dysfunction" for studies published from 2009 to 2017...

OBJECTIVE: To investigate parental age in relation to the severity of cleft diagnosis in a population-based consecutive sample of individuals with clefts. SETTING/SAMPLE: Retrospective, consecutive. MATERIAL/METHODS: The sample comprised 545 consecutive cases with nonsyndromic clefts (437 individuals with cleft lip with/without cleft palate [CL ± P] and 106 individuals with isolated cleft palate [CP]) and parental ages recorded. The groups were subdivided according to the extent/severity of cleft...

The aim of this review was to evaluate available evidence on the effect of early orthodontic management and myofunctional treatment in the developing dentition children, on anterior open bite correction, as well as on normalization of patterns of mouth breathing, swallowing and tongue resting position and pressure. Electronic searches in MEDLINE, Cochrane and LILACS, without language restrictions were conducted. Additionally, unpublished literature was identified. Randomized controlled trials, or controlled clinical trials, comparing interventions applied to manage anterior open bite and other muscle functions such as breathing/swallowing pattern and tongue resting position and pressure, were considered...

The aim of this systematic review was to assess qualitative changes induced by fixed appliance orthodontic treatment on the subgingival microbiota. Seven databases were searched up to August 2017 for randomized and nonrandomized clinical studies assessing the effect of orthodontic appliances on the subgingival bacteria in human patients. After elimination of duplicate studies, data extraction and risk of bias assessment according to the Cochrane guidelines, random-effects meta-analyses of relative risks (RR) and their 95% confidence intervals (CIs) were performed...

OBJECTIVES: To identify the genetic basis of severe tooth agenesis in a family of three affected sisters. PATIENTS AND METHODS: A family of three sisters with severe tooth agenesis was recruited for whole-exome sequencing to identify potential genetic variation responsible for this penetrant phenotype. The unaffected father was tested for specific mutations using Sanger sequencing. Gene discovery was supplemented with in situ hybridization to localize gene expression during human tooth development...
