Validity and Reliability of a New Optoelectronic System for Measuring Active Range of Motion of Upper Limb Joints in Asymptomatic and Symptomatic Sub…
2019
The aim of this study was to evaluate the validity of the Veloflex infrared dynamic angle-meter (Veloflex-IDA) and the intra- and inter-rater reliability when measuring the ranges of motion (ROMs) of the upper limb joints. Thirty-five healthy and 20 symptomatic participants were evaluated. Twelve upper limb movements were measured in two sessions with the Veloflex-IDA, which is a device composed of a camera that tracks the trajectory of retro-reflective markers. In addition, a goniometer was used in the first session to evaluate concurrent validity. Validity and agreement were evaluated by Pearson correlation coefficient (r) and Bland&ndash
Pattern of distribution and etiologies of Midline diastema among Kurdistan-region Population
2020
Background Aim of study was to evaluate the prevalence and etiological factors that contribute in midline diastema in Kurdistan region-Iraq population among different age groups and genders. Material and Methods Orthodontic patients sample of (EX: 1021orthodontic patients (537 males and 484 females) were randomly selected from Kurdistan-region population, attending to orthodontic department of khanzad polyclinic teaching center (General directorate of hawler / Ministry of health/ Kurdistan region- Iraq) during 2018-2019 period. Aged (13-35 years) with mean age ± SD was 19.6 ± 4.8 years, with a median of 19 years. The examination included patient history taking, intraoral examination, photog…
Incidence, severity and orthodontic treatment difficulty index of impacted canines in Saudi population
2018
Background The objective of this study was to assess the incidence, severity and orthodontic treatment difficulty of impacted maxillary canines in Saudi population. Material and methods This retrospective study included an investigation of panoramic radiographs for patients attended College of Dentistry, Jazan University, Saudi Arabia. The incidence of canine impaction and orthodontic treatment difficulty index of maxillary canine impaction was assessed based on; (1) patient age, (2) vertical position, (3) buccolingual position, (4) horizontal position, (5) incisors alignment, (6) canine space, (7) midline coincidence, (8) rotation of impacted tooth. Statistical analyses were calculated by …
Sagittal Plane Hip, Knee, and Ankle Biomechanics and the Risk of Anterior Cruciate Ligament Injury: A Prospective Study
2018
Background: Stiff landings with less knee flexion and high vertical ground-reaction forces have been shown to be associated with an increased risk of anterior cruciate ligament (ACL) injury. The literature on the association between other sagittal plane measures and the risk of ACL injuries with a prospective study design is lacking. Purpose: To investigate the relationship between selected sagittal plane hip, knee, and ankle biomechanics and the risk of ACL injury in young female team-sport athletes. Study Design: Case-control study; Level of evidence, 3. Methods: A total of 171 female basketball and floorball athletes (age range, 12-21 years) participated in a vertical drop jump test usin…

A comparative study of aesthetic perceptions of malocclusion among general practice dentists, orthodontists and the public using a visual analogue sc…
2016
Background Perception of malocclusion varies among individuals and among patients and practitioners. Although several indices that tend to coincide in many aspects and unify criteria, no single index has been recognised as the most suitable for assessing orthodontic treatment need. Moreover, orthodontists are not always aware of the differences in perception of malocclusion between patients and practitioners. Objetives To examine the perception of dental anaesthetics amongst dentists, orthodontists and the general population, study the relationship between the perception of dental aesthetics and the severity of the malocclusion, using the visual analogue scale and the IOTN-AC, and investiga…
Spectrophotometric evaluation of dental bleaching under orthodontic bracket in enamel and dentin
2013
Aware of the diffusion capacity of bleaching in the dental tissues, many orthodontists are subjecting their patients to dental bleaching during orthodontic treatment for esthetic purposes or to anticipate the exchange of esthetic restorations after the orthodontic treatment. For this purpose specific products have been developed in pre-loaded whitening trays designed to fit over and around brackets and wires, with clinical efficacy proven. Objective: The objective of this study was to evaluate, through spectrophotometric reflectance, the effectiveness of dental blea - ching under orthodontic bracket. Material and methods: Thirty-two bovine incisors crown blocks of 8 mm x 8 mm height lengths…
Linee guida in ortodonzia e attuale valutazione dei profili di responsabilitÃ
2016
Alla luce della nuova legge entrata in vigore in Italia, si discute il valore protettivo delle linee guida in ortodonzia sotto il profilo medico-legale. OBJECTIVES. In view of the Italian law recently come into force, this study aims at discussing the protective value of orthodontic guidelines in terms of legal medicine. MATERIALS AND METHODS. A review of orthodontic guidelines was conducted, including general orthodontic guidelines as well as specific guidelines for clinical and surgical cases. RESULTS AND CONCLUSIONS. Orthodontic practices envisaging professional liability include diagnosis, prevention, interception, care planning and treatment of all types of malocclusion (even when asso…
Accuracy of Computer-Aided Dynamic Navigation Compared to Computer-Aided Static Navigation for Dental Implant Placement: An In Vitro Study
2019
Aim: To analyze the accuracy capability of two computer-aided navigation procedures for dental implant placement. Materials and Methods: A total of 40 dental implants were selected, which were randomly distributed into two study groups, namely, group A, consisting of those implants that were placed using a computer-aided static navigation system (n = 20) (guided implant (GI)) and group B, consisting of those implants that were placed using a computer-aided dynamic navigation system (n = 20) (navigation implant (NI)). The placement of the implants from group A was performed using surgical templates that were designed using 3D implant-planning software based on preoperative cone-beam computed…
Factors influencing orthodontic treatment time
2021
Ievads: Šī literatūras pārskata mērķis ir aprakstīt faktorus, kuri literatūrā minēti kā ietekmējoši ortodontiskās ārstēšanas ilgumu. Pārskata hipotēze bija tāda, ka ilgāks ārstēšanas laiks ir saistīts ar sarežģītāku diagnozi. Metodes: Šajā pārskatā tika izmantoti 133 literatūras avoti angļu valodā no 1945. līdz 2021. gadam, iesaistot bērnus, pusaudžus un pieaugušos pacientus. Rezultāti: Lielākā daļa autoru ziņo, ka ekstrakcijām, II klases sakodienam, retinētiem kanīniem un faktoriem, kas saistīti ar pacienta atbilstību, bija nozīmīga ietekme uz ārstēšanas laiku. Nav konstatēta saikne starp vecumu un ārstēšanas ilgumu. Secinājumi: P…
