Methods: Thirty-two patients (24 female, 8 male; mean age, 19.26 ± 2.

Outcomes of Palatal Lift Prosthesis on Dysarthric Speech.

Purpose: This study was designed to investigate the effect of palatal lift prosthesis (PLP) on the speech of individuals with different types of dysarthria.

Participants: Thirty (19 males and 11 females) native speakers of Jordanian Arabic with dysarthria participated in the study. The age of the participants ranged from 8 to 67 years with an average of 34.

Pain experience during initial alignment with three types of nickel-titanium archwires: a prospective clinical trial.

Objective: To clinically evaluate the pain intensity during the week following initial placement of three different orthodontic aligning archwires.

Materials And Methods: A consecutive sample of 75 patients requiring upper and lower fixed orthodontic appliances were alternately allocated into three different archwires (0.014-inch superelastic NiTi, 0.

The relationship of vocal tract dimensions and substitution of the palatal approximant /j/ for the alveolar trill /r/.

Purpose: To investigate the relationship of the vocal tract dimensions and dental arches in participants with substitution of palatal approximant /j/ for the trill variant of /r/.

Method: Cephalograms and dental casts of 60 native speakers of Arabic were used for comparison. The experimental group included 30 participants with substitution of /j/ for the trill variant of /r/ (17 males and 13 females, age ranged between 15-20 years, M = 18.

Comparison of personality traits, attitude toward orthodontic treatment, and pain perception and experience before and after orthodontic treatment.

Objective: To compare personality traits, attitude toward orthodontic treatment, and pain perception and experience before and after orthodontic treatment.

Materials And Methods: One hundred subjects (50 male and 50 female) were included in this study. The mean (SD) age was 17.

A clinical comparison of three aligning archwires in terms of alignment efficiency: A prospective clinical trial.

Objectives: To clinically evaluate the effectiveness of three orthodontic aligning archwires in relation to tooth alignment speed during the initial alignment stage of treatment.

Materials And Methods: A consecutive sample of 74 patients requiring lower only or upper and lower fixed orthodontic appliances were randomly allocated into three different archwires (0.014-inch superelastic nickel-titanium [NiTi], 0.

Mandibular symphysis morphology and dimensions in different anteroposterior jaw relationships.

Objective: To assess the morphology and dimensions of mandibular symphysis (MS) in different anteroposterior jaw relationships and to investigate whether craniofacial parameters have any correlation with its shape and/or dimensions.

Materials And Methods: Lateral cephalograms of subjects with Class I, Class II, and Class III skeletal relationships were traced. Several craniofacial and MS parameters were measured.

Effect of fixed orthodontic appliances bonded with different etching techniques on tooth color: a prospective clinical study.

Introduction: For most orthodontic patients, esthetic concerns are as important as functional demands. The purpose of this study was to assess the effect of self-etching primer and conventional acid etching on tooth color after orthodontic treatment.

Methods: A total of 34 patients were enrolled in a clinical trial and divided into 2 groups based on age: adolescents (≤17 years) and adults (>17 years).

Alveolar bone density changes around miniscrews: a prospective clinical study.

Introduction: Our objective was to assess the effects of miniscrews on interproximal alveolar bone density and adjacent gingival tissue health.

Methods: Forty-four titanium miniscrews were inserted between maxillary second premolars and first molars on both sides of the dentition in 22 consecutive patients (15 female, 7 male; ages, 14-24 years). A control area (between the maxillary first and second premolars) was also assessed.

First premolar extraction effects on upper airway dimension in bimaxillary proclination patients.

Objective: To determine how orthodontic treatment with first premolar teeth extracted and the associated arch dimensional changes in bimaxillary proclination patients affect the upper airway dimensions.

Materials And Methods: Pre- and postorthodontic treatment cephalograms and dental casts of 40 bimaxillary proclination patients (ages ranged between 18 and 23 years) were used for this study. Patients were all treated with extraction of the four first premolars.

Factors affecting demineralization during orthodontic treatment: a post-hoc analysis of RCT recruits.

Introduction: Our aim was to determine predictors for the presence and degree of demineralization during orthodontic treatment. This study was a post-hoc analysis of recruits for a randomized controlled trial. Two hundred thirty patients were included in this study and assessed for demineralization at debond by using quantitative light-induced fluorescence to determine their eligibility for a randomized controlled trial assessing the effectiveness of various toothpastes at reducing demineralization during retention.
