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…
Condylar form alteration on skeletal class II patients that underwent orthognathic surgery : an overview of systematic reviews
2020
Background Bilateral sagittal split osteotomy (BSSO) is commonly considered as the surgical technique of election for the treatment of skeletal class II with mandibular hypoplasia. After orthognathic surgery, condylar resorption can occur as a surgical relapse, which may affect the temporomandibular joint. Objective: This study aimed to summarise published systematic review that assess if orthognathic surgery with mandibular advancement performed on skeletal class II patients results in condylar form alteration. Material and methods A literature search was performed using the electronic databases PubMed, Web of Science, Cochrane Library, Embase along with several sources of grey literature.…
Association between maxillary and mandibular apical base lengths and severity of dental crowding or spacing in Class II malocclusion subjects: An
2018
Background Anterior crowding/ spacing are one of the major problems that inspire patients to undergo orthodontic treatment. Several factors associated with anterior crowding/ spacing includes arch width and length, mesio-distal tooth diameter and proportions. The aim of the present study was to evaluate the relationship of maxillary and mandibular base lengths to the amount of anterior dental crowding/ spacing in patients with complete class II malocclusions. Material and methods A retrospective study was done with 152 patients who were divided into four groups according to the severity of pre-treatment dental crowding/spacing present in the mandibular arch. Measurements were performed on t…
Craniofacial Signs, Symptoms and Orthodontic Objectives of Paediatric Obstructive Sleep Apnoea
2019
The study of craniofacial growth and development has a long history in the disciplines of Paediatric Dentistry and Orthodontics. Unbalanced facial growth is known to be causative for dental misalignment and malocclusion. However, historically, little emphasis has been placed on the possible link to obstructive sleep apnoea. Through greater understanding from contemporary studies and reflections from past research, we now are bringing to light the interrelationships of all proximal structures in the many chronic issues that ail our children.
Adverse effects of lingual and buccal orthodontic techniques: A systematic review and meta-analysis
2016
INTRODUCTION: The aim of this systematic review was to assess the prevalence of adverse effects associated with lingual and buccal fixed orthodontic techniques. METHODS: Two authors searched the PubMed, EMBASE, Cochrane Library, and LILACS databases up to October 2014. Agreement between the authors was quantified by the Cohen kappa statistic. The following variables were analyzed: pain, caries, eating and speech difficulties, and oral hygiene. The Newcastle-Ottawa scale was used to assess risk of bias in nonrandomized studies, and the Cochrane Collaboration's tool for assessing risk of bias was used for randomized controlled trials. RESULTS: Eight articles were included in this systematic r…
Dental implants placement in paranoid squizofrenic patient with obsessive-compulsive disorder: A case report
2017
Background Paranoid schizophrenia is a mental illness that involves no observable anatomical alteration. Main characteristic affects the personality of the individual, as well as areas of his own psychology. Case report A 33-year-old man with paranoid schizophrenia and obsessive-compulsive disorder in treatment with Haloperidol, Oxcarbazepine, Olanzapine and Seroquel is presented. Dental exploration showed widespread decay mostly cervical with numerous root fragments, agenesis of lateral incisors, impacted wisdom teeth, missing teeth and malocclusion. Treatment plan included restoration of teeth decay, extractions of root fragments and implant-supported prostheses in bilateral upper lateral…
Association between malocclusion and orofacial myofunctional disorders of pre‐school children in Latvia
2019
Objects Abnormal use of muscles of tongue and lips is called orofacial myofunctional disorders (OMD). In this study, we aimed to investigate the interrelation between occlusal findings and OMD in primary and mixed dentition and to find out the reasons for malocclusions, and the effect modification of these associations by the number of sources that parents used to receive the information on child oral health issues (NSI). Setting and sample population Cross-sectional study was performed in one kindergarten in Latvia (cluster sampling). The study sample comprised 141 children-mothers' pairs of pre-school children aged 4-7 years. Materials and methods Children' myofunctional situation, occlus…
Dentofacial abnormalities among adolescents: A study on the prevalence and severity.
2014
Background The objectives of this investigation were to assess prevalence and severity of dentofacial abnormalities and orthodontic treatment need among adolescents in Mangalore taluk. Material and Methods A cross-sectional study was conducted among 1340 children from randomly selected high schools. A proforma was used to record demographic data and components of the Dental Aesthetic Index [DAI] for each subject. The Chi squared test was used for analysis with p-value of 0.05). Assessment of severity of malocclusion between age groups revealed no differences (p > 0.05). Orthodontic treatment was highly desirable in 11% and mandatory in 5.2% subjects. Conclusions A high prevalence of dentofa…
Dentofacial aesthetics and quality of life
2007
This article reviews, from the socio-psychological perspective on physical attractiveness, recent research on the psychosocial impacts of dental aesthetics. Research on personal impression forming suggests that visual perceptions of detrimental dental conditions might lead to conclusions about social impairments of the target person. Consumers conform considerably with professional assessment of dental aesthetics. Psychosocial impacts of dental appearance in childhood include teasing by peers. Existing research suggests that dental aesthetics contributes to psychosocial well-being of both children and adults. The concept of public self-consciousness is introduced for explaining differences …
Prevalence of maxillary canine impaction in skeletal Class III malocclusions compared to Class I malocclusions
2019
Background The aim of the present investigation was to evaluate if an orthodontic population of Class III malocclusion patients shows a different prevalence of maxillary canine impaction than Class I subjects. Material and methods Fifty-eight subjects were retrospectively selected and assigned to the Class I group (n= 32) or the Class III group (n= 26), depending on the ANB and WITS values. Lateral cephalograms were used to collect angular and linear measurements that described the skeletal and dental maxillary features of the subjects, while orthopantomography was used to assess the impaction or the correct eruption of the maxillary canines. An independent samples T-test or a Mann-Whitney …
