Effect of use of antiseptics and fluorides during orthodontic treatment on working properties of NiTi archwires in levelling dental arches : A randomized controlled trial.

Purpose: The goal was to investigate whether the application of antiseptics and fluorides during orthodontic treatment affects the biomechanics of the levelling of dental arches by changing the working properties of nickel-titanium (NiTi) archwires.

Methods: The sample consisted of 60 individuals aged 12-22 years (53% females). There were 20 individuals in each experimental group: (I) individuals conducted regular oral hygiene, (II) individuals used a high concentration of fluorides for intensive prophylaxis for the first month; and (III) individuals used chlorhexidine in the same manner.

Patients with gingival enlargement received initial periodontal therapy, followed by external gingivectomy in the case of persistent gingival enlargement. The sample included 44 patients (22 had metal allergic sensitisation).

Objectives: To explore the relationship between adolescents' oral health-related quality of life (OHRQoL), satisfaction with smile appearance, treatment need and treatment demand through direct and serial mediation models.

Materials And Methods: This cross-sectional study included 215 11-14-year-olds and their parents. The instruments included the Child Perceptions Questionnaire and the Index of Orthodontic Treatment Need.

Clinical predictors of metal allergic sensitization in orthodontic patients.

Objectives: This study aimed to assess the predictors of allergic sensitisation to titanium and nickel in patients undergoing orthodontic treatment.

Methods: A total of 250 patients undergoing orthodontic treatment were invited to participate, and 235 were analysed (67% females). A patch test was performed using nickel sulphate, titanium, titanium dioxide, titanium oxalate, titanium nitride, and petrolatum as control.

Impacts of childhood malocclusion on the family.

Purpose: To analyze the effects of children's malocclusions and associated quality of life on family relationships by evaluating psychometric characteristics of the Family Impact Scale (FIS) in adolescents seeking orthodontic treatment.

Materials And Methods: Included were 334 participants (children aged 11-14 years; 53% female and 47% male) and their parents (84% mothers, 16% fathers) who were recruited at two dental clinics in Croatia. The Child Perception Questionnaire, Parental-Caregiver Perception Questionnaire, and FIS were administered.

Oligomicrodontia in a Pediatric Cancer Survivor after Chemotherapy: A Case Report.

Chemotherapy used on pediatric patients especially those below 3 years of age causes disturbances in dental development. The aim of this case report was to present the late dental effects of chemotherapy in a patient treated for anaplastic ependymoma (WHO III) at an early age. Radiographic findings at the age of 9 years showed oligomicrodontia of six teeth, maxillary lateral incisors, and maxillary and mandibular first premolars.

Influence of personality traits on a patient's decision to accept orthognathic surgery for correction of dentofacial deformity.

Objectives: To investigate the influence of personality traits in addition to quality of life (QoL) on the decision to accept orthognathic surgery.

Materials And Methods: A total of 108 patients (68% female) aged 14-53 years (median, 18 years; interquartile range, 17-25.75 years), with skeletal malocclusions of Index of Orthognathic Functional Treatment Need grades 3-5 (moderate to very great need for surgery) were included in this cross-sectional study.

Presence and Maturation Dynamics of Mandibular Third Molars and Their Influence on Late Mandibular Incisor Crowding: A Longitudinal Study.

The objective of this study was to investigate the relationship between the absence, presence and dynamics of mandibular third molar development and the occurrence and amount of late mandibular incisor crowding. Dental plaster casts and panoramic radiographs of 72 orthodontically untreated subjects from the Nittedal growth study, Norway were analyzed. The subjects were recalled for a checkup at 12, 15, 18 and 21 years of age.

Facial aesthetic concern is a powerful predictor of patients' decision to accept orthognathic surgery.

Objective: To investigate differences in quality of life in subjects with and without skeletal malocclusions and factors influencing patients' decision to accept orthognathic surgery.

Materials And Methods: DESIGN: Cross-sectional with stratified sampling.

Settings And Sample Population: 190 Caucasian subjects (65% females), aged 17-46 years.

Craniofacial Growth in Adolescence and its Influence on the Mandibular Incisor Crowding.

Background: To analyze craniofacial growth during adolescence from the ages of 12 to 21 years and its relation to late mandibular incisor crowding.

Material And Methods: The study included 61 orthodontically untreated subjects (49% males). Lateral cephalograms were used to assess the jaw growth and inclination of the incisors.

Predictors of patient compliance during Class II division 1 malocclusion functional orthodontic treatment.

Objectives: To determine factors that could predict Class II/1 malocclusion patient compliance during functional treatment.

Materials And Methods: The sample consisted of 77 subjects (aged 11-13 years; 47% girls) presenting with Class II/1 malocclusion. Inclusion criteria were distal molar relationship, overjet greater than 5 mm, and confirmed pubertal growth spurt.

Symptoms of titanium and nickel allergic sensitization in orthodontic treatment.

Aim: The study aimed to evaluate to which extent self-reported symptomatology, age, and sex are predictors of titanium and nickel allergic sensitization in patients in treatment with fixed orthodontic appliances.

Methods: The study analyzed 228 subjects aged 11-45 years (median 18, interquartile range 16-22); 68% of them were females, and 52% were adolescents. The allergic sensitization testing included epicutaneous patch test to titanium, titanium dioxide, titanium oxalate, titanium nitride, and nickel sulfate.

Smell and taste in titanium and nickel allergic sensitization in orthodontic patients.

Objective: To assess the prevalence of allergic sensitization to titanium and nickel in orthodontic patients and to evaluate alterations of smell and taste.

Subjects And Methods: A total of 250 subjects were invited to participate, 245 accepted. The age range was 11-45 years, 68% were females and 52% adolescents.

Changes of mandibular dental arch shape during adolescence and its influence on late mandibular incisor crowding.

The aim was to analyze the changes in mandibular dental arch shape during adolescence and assess its relation to late mandibular incisor crowding. Longitudinal study included 68 orthodontically untreated subjects (49% female) and analyzed their data for the ages of 12, 15, 18 and 21 years. Measurements included anterior arch depth, intercanine, interpremolar/anterior and intermolar/posterior width, Little's Irregularity and Bolton's index and the ratio between anterior arch depth and width.
