The pattern of malocclusion in a sample of orthodontic patients from Turkey.
2009
Objective: The objective of this study was to determine the prevalence of individual traits of malocclusion in a sample of Turkish orthodontic patients. Study design: The present study was based on the examination of dental casts, intraoral photographs and panoramic radiographs of 1507 orthodontic patients (884 females and 623 males). The relationship of the first upper and lower molars according to the Angle?s classification, overjet, overbite, crowding, spacing, posterior crossbite, scissor bite, maxillary median diastema were examined. The Pearson chi-squared and Fisher?s Exact tests were used to determine potential differences in the distribution of malocclusion when stratified by gende…
Psychosocial impact of malocclusion in Spanish adolescents
2013
Objective: To evaluate the psychosocial impact of malocclusion, determine its relationship with the severity of malocclusion, and assess the influence of gender and social class on this relationship in adolescents. Methods: A random sample of 627 Spanish adolescents aged 12 - 15 years underwent intraoral examinations by 3 calibrated examiners (intraexaminer and interexaminer kappa > 0.85) at their schools. Psychosocial impact was measured through a self-rated Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ). The severity of malocclusion was measured by the Index of Orthodontic Treatment Need (IOTN). Gender and social class were also recorded. Results: The total PIDAQ score and…
Prevalence of traumatic dental injuries and role of incisal overjet and inadequate lip coverage as risk factors among 4-15 years old government schoo…
2010
Objective: To assess the prevalence of traumatic dental injuries (TDI) in school children in Baddi- Barotiwala, Himachal Pradesh, India. Methods: A cross-sectional survey was carried out in Government schools among 1059 government school children aged 4- 15 years. The study was conducted from October 2009 to March 2010 during the school hours. The demographic detail was carried on a structured questionnaire. The data regarding the traumatic injuries was recorded using modified Ellis' classification. Results: Prevalence of TDI was found to be 4.15%. 95.45% of the injuries were to the maxillary anterior teeth. Maxillary central incisor was the most common tooth to be affected due to trauma (5…
Long-term analysis of upper incisor crowding. A longitudinal study orthodontically treated patients
2010
Introduction: Although there are numerous studies in the literature on alignment stability in the lower arch, there are few referring to the upper arch. Aims: To assess upper arch stability (irregularity index, widths and length of arch, overjet and overbite) in orthodontically treated patients by comparing late incisor stability with the initial malocclusion and type pf treatment undertaken. Study design: The study models of 51 patients, treated with or without extractions, were analysed at three different points in time: pre-treatment (T1), post-treatment (T2) and post-retention (T3) (average 5 years). The following parameters were measured: irregularity index, arch length, inter-canine a…
Resting position of the head and malocclusion in a group of patients with cerebral palsy
2014
Cerebral palsy are found as a result of these disorders, along with associated neuromuscular functional alterations that affect the resting position of the head. In this context, the resting position of the head could be responsible for several skeletal and dental occlusal disorders among patients with cerebral palsy. Objective: To assess the presence of malocclusions in patients with cerebral palsy, define the most frequent types of malocclusions, and evaluate how the resting position of the head may be implicated in the development of such malocclusions. Study design: Forty-four patients aged between 12-55 years (18 males and 26 females) were studied. Occlusal conditions, the Dental Aesth…
Maximum occlusal bite force in pre-school children with different occlusal patterns
2018
Background This study was carried out to record maximum occlusal bite force (MOBF) in pre-school children with different occlusal patterns. Material and Methods A randomly selected sample of 1085 kindergarten children in primary dentition stage were selected. The age of subjects ranged between 3-6 years (averaged 4.90 ± 0.86 years). The subjects were divided into 3 groups according to molar relationship; flush terminal (n=335; 165 males and 170 females), distal step (n=450; 200 males and 250 females), mesial step (n=300; 150 males and 150 females) molar relationship. Clinical examination involved the record of molar relationship, overjet, overbite and the presence of wearing facets. Occlusa…
Dentoskeletal effects of class II malocclusion treatment with the modified Twin Block appliance
2019
Background The purpose of this study was to prospectively assess the dentoskeletal effect of a modified Twin Block appliance for treatment of class II malocclusions. Material and Methods Lateral cephalograms of 25 Class II malocclusion patients were compared to evaluate skeletal, dentoalveolar and soft tissue changes pre- and post-treatment with a modified Twin Block appliance. A total of 33 angular and linear variables were used for analysis. The differences were calculated at the start and end of treatment. The paired T test was performed to compare the cephalometric measurements before and after treatment. Results Compared the pre- and post- treatment measurements, there was a significan…
Effectiveness of interceptive treatment of class III malocclusions with skeletal anchorage: A systematic review and meta-analysis
2017
Recently, new strategies for treating class III malocclusions have appeared. Skeletal anchorage appears to reduce the dentoalveolar effects while maximising the orthopaedic effect in growing patients. The purpose of this systematic review and meta-analysis is to examine the effectiveness of bone anchorage devices for interceptive treatment of skeletal class III malocclusions. Searches were made in the Pubmed, Embase, Scopus and Cochrane databases, as well as in a grey literature database, and were complemented by hand-searching. The criteria for eligibility were: patients who had undergone orthodontic treatment with skeletal anchorage (miniplates and miniscrews). Patients with syndromes or …
Influencia de la práctica instrumental en el sistema orofacial
2014
Introducción. El aparato estomatognático es muy importante para los instrumentistas de viento ya que les permite la ejecución musical. Por lo tanto, les debería preocupar su estado en cuanto a función y salud. Se ha observado que una maloclusión puede afectar a la correcta posición del instrumento en la boca, al igual que tocar instrumentos de viento podría influir en el esqueleto dentofacial. Sin embargo la exacta relación entre ellos no se conoce en profundidad. Es a esta relación a lo que pretendemos aportar con este trabajo. Objetivos. El propósito general es valorar los cambios y patologías orofaciales asociadas, con relación de causa-efecto, a la práctica con instrumentos musicales de…
Does breastfeeding have a long-term positive effect on dental occlusion?
2019
Background Breastfeeding produces beneficial effects on a baby's early growth and development, and general well-being. Some studies have associated breastfeeding with better occlusal development. The aim of this study was to assess the long-term effect of breastfeeding on occlusal development in children. Material and methods A retrospective cohort study was conducted to evaluate the occlusions of 320 children belonging to the Spanish INMA Project cohort, monitored from gestation onwards. The association between the duration of breastfeeding and different occlusal traits in mixed dentition (overjet, overbite, openbite, midline displacement, incisor crowding, incisor spacing, diastema, maxim…
