Prevalencia de Anomalías Dentomaxilares y Necesidad de Tratamiento Ortodóncico en Escolares del Pueblo Originario Rapa Nui / Prevalence of Dentomaxillary Anomalies and Need for Orthodontic Treatment in School Children of the Rapa Nui Native People

El objetivo de este estudio fue determinar la prevalencia de anomalías dentomaxilares y la necesidad de tratamiento ortodóncico en escolares pertenecientes al pueblo originario de Rapa Nui. Se realizó un estudio descriptivo, observacional, transversal y no probabilístico. Se evaluaron 85 alumnos entre primero básico y primero medio, entre los 6 y 16 años de edad, de dos colegios de Rapa Nui. Se realizó un examen clínico estandarizado, realizado por dos investigadores previamente calibrados, donde se completó una ficha clínica diseñada para el estudio. Para el análisis de las anomalías dentomaxilares se realizó un escaneo digital de la cavidad oral completa para su posterior análisis. De 85 estudiantes evaluados, 75 (88,2 %) se encontraban afectados por algún tipo de anomalía dentomaxilar en el plano sagital, vertical y/o transversal, independiente de su gravedad. Un 87,1 % de los estudiantes necesitan tratamiento ortodóncico según el Índice de Necesidad de Tratamiento Ortodóncico, de los cuales un 57,7, % se clasificó dentro de los rangos de moderado, grave y muy grave. Existe una alta prevalencia de anomalías dentomaxilares en los escolares pertenecientes al pueblo originario Rapa Nui, encontrándose por sobre las cifras nacionales como internacionales, lo cual da como resultado que la mayoría de los alumnos evaluados necesiten de algún tipo tratamiento ortodóncico, ya sea preventivo, interceptivo y/o correctivo.

The aim of this study was to determine the prevalence of dentomaxillary anomalies and the need for orthodontic treatment in schoolchildren belonging to the Rapa Nui native people. A descriptive, observational, cross- sectional and non-probabilistic study was carried out. Eighty- five students between first grade and first middle school, between 6 and 16 years of age, from two schools of Rapa Nui were evaluated. A standardized clinical examination was performed by two previously calibrated investigators, where a clinical record designed for the study was completed. For the analysis of dentomaxillary anomalies, a digital scan of the full mouth was performed for subsequent analysis. Of 85 students evaluated, 75 (88.2 %) were affected by some type of dentomaxillary anomaly in the sagittal, vertical and/or transversal plane, regardless of its severity. Some 87.1 % of the students needed orthodontic treatment according to the Orthodontic Treatment Need Index, of which 57.7 % were classified within the moderate, severe and very severe ranges. There is a high prevalence of dentomaxillary anomalies in schoolchildren belonging to the Rapa Nui native people, which is above the national and international figures, resulting in the majority of the students evaluated needing some type of orthodontic treatment, whether preventive, interceptive and/or corrective.

A double-blinded randomized clinical trial of pain perception during orthodontic treatment / Ensaio clínico randomizado duplo cego de percepção da dor durante tratamento ortodôntico

Introduction: Orthodontic movement can cause painful symptoms, especially in the early stages of treatment. Objective: This study aimed to compare the performance of chewing gum and ibuprofen in pain control during the initial period of orthodontic treatment. Material and method: A randomized blind clinical trial, with an allocation ratio of 1:1, was developed with patients aged ≥18 years old. The sample size was established considering a significance level of 5% and test power of 80%, resulting in a minimum of 30 volunteers per group (n=90). Participants were paired regarding sex, age, the severity of malocclusion, defined by the Dental Health Component (DHC) of the Index of Orthodontic Treatment Need (IOTN), and crowding, determined by Little's irregularity index. The sample was randomly allocated to three groups: Group I (control) placebo; Group II chewing gum; and Group III Ibuprofen. Pain perception was evaluated by the Visual Analog Scale (VAS) in the first 24, 36, and 48 hours after activation of the orthodontic appliance. The data were analyzed by generalized linear models for repeated measures in time. Result: No statistically significant difference (p>0.05) was observed among the groups for the methods of pain therapy evaluated in 24, 36, and 48 hours post-activation. Conclusion: There was no difference among the method used for pain control during the orthodontic treatment.

A Multivariate Analysis of the Psychosocial Impact of Malocclusion and Self-Esteem in Adolescents

Abstract Objective: To evaluate the psychosocial impact of malocclusion and self-esteem in adolescents in the Amazon region. Material and Methods: A cross-sectional study was carried out with 212 adolescents with 12-year-old enrolled in all public schools in the Boca do Acre (Amazonas, Brazil). Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ) assessed the psychosocial impact of malocclusion. The self-perception of the need for orthodontic treatment was evaluated by the Aesthetic Component (AC) of the Index of Orthodontic Treatment Need (IOTN) and Global Negative Self-evaluation (GSE), the adolescent's self-esteem. The malocclusion was clinically evaluated by the Dental Aesthetic Index (DAI). The variables with p<0.20 in the individual analyses were tested in multiple logistic regression models, and those with p<0.10 remained in the model. The adjusted odds ratio (OR) was estimated with a 95% confidence interval (CI). Results: Adolescents with low self-esteem were 2.20 (95% CI: 1.23-3.93) times more likely to have a more significant impact on dental aesthetics (p<0.05). When verified by domains, the adolescents with low self-esteem had 2.33 (95% CI: 1.31-4.17) and 1.93 (95% CI: 1.09-3.42) times more likely to impact the psychological and social domains of the PIDAQ, respectively. Conclusion: Self-esteem influenced adolescents' perception of dental aesthetics in the domains related to psychological and social impact (AU).

Assessment of the need for orthodontic treatment in a peruvian sample using the dental aesthetic index / Necesidad de tratamiento ortodóntico en una muestra peruana mediante el índice estético dental

Introduction: The Dental Aesthetic Index (DAI) is considered an essential tool in the association of the aesthetic and clinical elements of occlusion. It plays a key role in the timely and essential orthodontic treatment. Objective: to determine the orthodontic treatment required in students of a Peruvian public institution using the DAI. Material and Methods: A descriptive, observational, cross-sectional study was carried out during the months of June to July 2016 in a Peruvian educational institution. The sample consisted of 120 students. The use of the DAI allowed to assess the orthodontic treatment required, through the 10 occlusal conditions and regression indicators that constitute a linear formula, with the following components: no treatment required, elective treatment, desirable treatment, and priority treatment, according to the severity of the malocclusion as normal, defined, severe, and very severe, respectively. Results: 53.3% (64) of the students required priority orthodontic treatment due to presenting DAI=43.03. Between the ages of 12-14 years, 56.7% (34), 8.3% (5), and 28.3% (17) required priority, desirable, and elective orthodontic treatment, respectively. The need for priority orthodontic treatment was more prevalent in females accounting for 57.6% (38). 95% (57) of the students from rural areas required orthodontic treatment. Conclusion: The need for orthodontic treatment in a Peruvian sample using the Dental Aesthetic Index was priority orthodontic treatment, mostly in females with ages ranging between 12-14 years.

Background: To correlate the need for orthodontic treatment between the self-perception of Chilean adolescents from 14 to 18 years old with the observation of a dentist using the same assessment scale, as well as to determine if covariates such as gender, age and type of school influence the self-perception of the adolescent and the examiner. Material and Methods: Cross-sectional descriptive study of adolescents aged 14 to 18 years from public, subsidized and private schools in Temuco, Chile. The probability sample is stratified by course, from first to fourth year, a total of 414 students participated, according to the eligibility criteria. The photographic score of the aesthetic component (AC) of the Index of Orthodontic Treatment Need (IOTN) was used. The statistical analysis of the data was performed with the SPSS Statistics program v.23. Results: 94.9% of the adolescents perceived themselves as having good aesthetics. The examiner considered that 77% presented this condition, p<0.00. Males perceived themselves better than females. At age 15, 1.7% of students considered themselves to have poor aesthetics, p<0.01. From the examiner's perspective, aesthetics are related to type of school, p<0.00. Conclusion: Adolescents perceive themselves better aesthetically than do the evaluators. The school type factor, according to the IOTN-AC examiner, shows a higher proportion of students with no need for orthodontic treatment in private schools, and a threshold need in municipal and subsidized institutions.

Ortodontia em saúde coletiva: epidemiologia das oclusopatias e da necessidade de tratamento ortodôntico em adolescentes / Orthodontics in public health: epidemiology of malocclusions and the need for orthodontic treatment in adolescents

A Epidemiologia tornou-se um ramo da ciência muito utilizado para a verificação das necessidades da população, o planejamento de ações e a organização dos serviços em saúde. Para isso, primeiramente, é fundamental realizar o diagnóstico situacional, a partir de dados específicos, em busca da compreensão e atuação sobre os problemas de saúde encontrados em coletividade. As oclusopatias têm sido uma das condições bucais mais prevalentes e, em consequência, houve o crescimento da demanda por tratamento ortodôntico. Nesta perspectiva, índices oclusais foram elaborados para medir a ocorrência das oclusopatias tendo em vista a priorização da necessidade de tratamento. O conhecimento da temática em escala global permitiu uma visão ampliada do problema e das estratégias desenvolvidas em saúde bucal. Neste contexto, a presente pesquisa teve os seguintes objetivos: 1) realizar uma revisão sistemática das evidências científicas existentes sobre a prevalência da necessidade de tratamento ortodôntico em adolescentes na faixa etária de 12 à 15 anos de idade; 2) investigar a prevalência das oclusopatias e a necessidade normativa de tratamento ortodôntico em adolescentes de 12 anos de idade. Na revisão sistemática foram incluídos trabalhos nacionais e internacionais publicados nas bases de dados Cochrane, Embase, Portal Regional da Biblioteca Virtual em Saúde (BVS), PubMed, Scientific Electronic Library Online (Scielo), Scopus e Web of Science (WOS). A busca inicial não se limitou a nenhum filtro disponível nas bases de dados e utilizou os seguintes descritores: prevalence, epidemiology, malocclusion, index orthodontic treatment need, child e adolescent. Termos utilizados na literatura científica também foram empregados: orthodontic treatment need, index for need of orthodontic treatment, index of orthodontic treatment needs, IOTN index, dental aesthetic index e DAI index. Foram incluídas publicações que avaliaram a prevalência da necessidade de tratamento ortodôntico em adolescentes entre 12 à 15 anos de idade utilizando o Índice de Estética Dentária (DAI) e/ou Índice de Necessidade de Tratamento Ortodôntico (IOTN) em estudos epidemiológicos transversais, sem restrições de ano do periódico e idioma. Do total de artigos encontrados (n=2255), 525 estudos permaneceram após a remoção por duplicidade. Os títulos e resumos destas publicações foram avaliados e aplicando os critérios de exclusão, selecionou-se 38 artigos. Para elegibilidade, os critérios de inclusão foram empregados e 11 estudos foram eleitos. Os textos completos destas publicações foram obtidos para leitura e análise da qualidade metodológica. Com relação aos achados da necessidade de tratamento ortodôntico global, houve variabilidade nos resultados, mas observou-se que a prevalência foi considerada alta. Quanto às ações desenvolvidas, foram sugeridas a educação em saúde bucal para os adolescentes e pais com foco na prevenção e no tratamento interceptativo precoce das oclusopatias, bem como, inserção da ortodontia nos programas de saúde com a implantação de mais centros especializados. A segunda etapa desta pesquisa consistiu em um estudo observacional e transversal, realizado com 461 adolescentes de 12 anos de idade, matriculados em escolas públicas de um município de médio porte do Estado de São Paulo. A oclusão e a necessidade de tratamento ortodôntico foram avaliadas por meio da Classificação de Angle e do DAI. Os dados foram analisados utilizando estatística descritiva e as distribuições absolutas e percentuais das variáveis categóricas foram tabuladas. A verificação da associação entre os resultados dos exames clínicos para diagnóstico de oclusopatias utilizando a Classificação de Angle e o DAI foi realizada por meio do teste G, adotando-se um nível de significância de 5%. O processamento e a análise dos dados foram realizados com auxílio do Programa Epi-InfoTM versão 7.2. (Center for Disease Control and Prevention). O diagnóstico da oclusão, segundo a Classificação de Angle, mostrou que 8,89% apresentavam oclusão normal, 56,83% oclusopatia em Classe I, 24,08% em Classe II e 10,20% em Classe III. A prevalência da necessidade de tratamento ortodôntico, segundo o DAI, foi de 52,69% dos adolescentes considerando tratamento eletivo à obrigatório. Houve associação entre os resultados dos exames clínicos para diagnóstico de oclusopatias utilizando a Classificação de Angle com o DAI (p <0,0001). A prevalência das oclusopatias e da necessidade normativa de tratamento ortodôntico foi elevada, sendo 18,44% dos adolescentes com necessidade de tratamento obrigatório. Os índices foram eficazes para a identificação das oclusopatias, entretanto por avaliarem aspectos clínicos distintos, poderiam ser utilizados concomitantemente para aprimorar o diagnóstico das oclusopatias(AU)

Epidemiology has become a branch of science widely used to define the needs of the population, plan actions and organize health services. For this, first, it is essential to perform the situational diagnosis, based on specific data, in search of understanding and acting on the health problems found in the community. Malocclusion has been one of the most prevalent oral conditions and, as a result, there has been an increase in demand for orthodontic treatment. In this perspective, occlusal indexes were developed to measure the occurrence of malocclusions in order to prioritize the need for treatment. The knowledge of the theme on a global scale allowed an expanded view of the problem and the strategies developed in oral health. In this context, the present research had the following objectives: 1) to carry out a systematic review of the existing scientific evidence on the prevalence of the need for orthodontic treatment in adolescents aged 12 to 15 years old; 2) to investigate the prevalence of malocclusions and the normative need for orthodontic treatment in 12-year-old adolescents.The systematic review included national and international works published in the Cochrane, Embase, Regional Portal of the Virtual Health Library (VHL Regional Portal), PubMed, Scientific Electronic Library Online (Scielo), Scopus and Web of Science (WOS) databases. The initial search was not limited to any filter available in the databases and used the following descriptors: prevalence, epidemiology, malocclusion, index orthodontic treatment need, child and adolescent. In addition, terms used in the scientific literature were also used: orthodontic treatment need, index for need of orthodontic treatment, index of orthodontic treatment needs, IOTN index, dental aesthetic index and DAI index. Were included publications that evaluated the prevalence of the need for orthodontic treatment in adolescents between 12 and 15 years of age using the Dental Aesthetic Index (DAI) and / or Orthodontic Treatment Needs Index (IOTN) in cross-sectional epidemiological studies, without restrictions on year of the journal and language. Of the total articles found (n = 2255), 525 studies remained after removal due to duplication. The titles and abstracts of these publications were evaluated and applying the exclusion criteria, 38 articles were selected. For eligibility, the inclusion criteria were used and 11 studies were elected. The complete texts of these publications were obtained for reading and analysis of methodological quality. As for the actions developed, oral health education recommendations were suggested for adolescents and parents with a focus on prevention and early interceptive treatment of malocclusions, as well as insertion of orthodontics in health programs with the implementation and development of specialized centers. The second stage of this research consisted of an observational, crosssectional, survey-type study conducted with 461 12-year-old adolescents enrolled in public schools in the medium-sized municipality of the State of São Paulo. Occlusion and the need for orthodontic treatment were assessed using the Angle Classification and the DAI. The data were analyzed using descriptive statistics and the absolute and percentage distributions of categorical variables were tabulated. The verification of the association between the results of clinical exams for the diagnosis of malocclusions using the Angle Classification and the DAI was performed using the G test, adopting a significance level of 5%. Data processing and analysis were performed using the Epi-InfoTM version 7.2 program. (Center for Disease Control and Prevention). The diagnosis of occlusion, according to the Angle Classification, showed that 8.89% had normal occlusion, 56.83% occlusion Class I, 24.08% Class II and 10.20% Class III. The prevalence of the need for orthodontic treatment, according to the DAI, was 52.69% of adolescents considering elective treatment to mandatory treatment. There was an association between the results of clinical examinations for the diagnosis of malocclusions using the Angle Classification with the DAI (p <0.0001). The prevalence of malocclusions and the normative need for orthodontic treatment was high, with approximately 18,44% of adolescents in need of mandatory treatment. The indices were effective for the identification of malocclusions, however, by evaluating different clinical aspects, they could be used concomitantly to improve the diagnosis of malocclusions(AU)

Affective relationships as predictors of TMD symptoms in young adults / Relações afetivas como preditoras de sintomas de DTM em adultos jovens

Abstract Introduction Orofacial pain is a critical TMD symptom that can influence physical and social capacity. Objective To evaluate the association of temporomandibular disorders (TMD) symptoms with affective relationships and demographic variables in young adults. Material and method A cross-sectional study involving 395 young adults was developed. Diagnostic Criteria for TMD, anxiety, and depression were collected from questionnaires. The Dental Health Component of the Index of Orthodontic Treatment Need measures the orthodontic treatment need. Questionnaires also contained questions related to the previous orthodontic treatment. Logistic regression models were adjusted, estimating crude odds ratio with the 95% confidence intervals. The variables with p<0.20 in the analyses were assessed in a multiple logistic regression model, remaining with p≤0.10. Result There was no significant association of TMD symptoms with sex, age, medication use for pain, previous orthodontic treatment, orthodontic treatment need, anxiety, and depression (p>0.05). Individuals without an affective relationship are 1.78 (95%CI: 0.99-3.17) times more likely to report TMD symptoms. Conclusion Affective relationships showed an association with TMD symptoms in young adults.

Resumo Introdução A dor orofacial é um sintoma crítico da DTM que pode influenciar a capacidade física e social. Objetivo Avaliar a associação dos sintomas das desordens têmporomandibulares (DTM) com as relações afetivas e variáveis demográficas em adultos jovens. Material e método Estudo transversal envolvendo 395 adultos jovens foi realizado. Os critérios diagnósticos para DTM, ansiedade e depressão foram coletados a partir de questionários. O Componente de Saúde Bucal do Índice de Necessidade de Tratamento Ortodôntico mensurou a necessidade de tratamento ortodôntico. Os questionários também continham questões relacionadas ao tratamento ortodôntico anterior. Modelos de regressão logística foram ajustados, estimando odds ratio bruto com os intervalos de confiança de 95%.

Resultado Não houve associação significativa dos sintomas de DTM com sexo, idade, uso de medicamentos para dor, tratamento ortodôntico prévio, necessidade de tratamento ortodôntico, ansiedade e depressão (p>0.05). Indivíduos sem relacionamento afetivo têm 1.78 (IC95%:0.99-3.17) vezes mais chance de relatar sintomas de DTM. Conclusão Os relacionamentos afetivos mostraram associação com os sintomas de DTM em adultos jovens.

Nature and severity of dental malocclusion in children suffering from transfusion-dependent (-thalassemia major

ABSTRACT Objective: To evaluate the prevalence and severity of malocclusion in children suffering from β-thalassemia and to assess orthodontic treatment need using Grainger's Treatment Priority Index (TPI) and index of orthodontic treatment need (IOTN)-dental health component (DHC). Methods: A cross-sectional study was conducted on 200 transfusion-dependent children diagnosed with homozygous β-thalassemia and 200 healthy school children aged 11-17 years. The TPI and IOTN-DHC data was recorded for both groups. Total TPI score for each subject was calculated and graded according to malocclusion severity estimate (MSE). Independent sample t-test was used to compare mean TPI scores, overjet and overbite between thalassemic and healthy children. Chi-square test was used to compare the frequency of IOTN-DHC grades, Angle's classification, and MSE grades between thalassemic and healthy children. Results: The most prevalent malocclusion was Class I in normal children (67.5%) and Class II in thalassemic children (59%). The mean overjet and overbite were significantly (p<0.001) greater in thalassemic children than in healthy children. Severe tooth displacements were 3.5 times greater in thalassemic children, compared to controls. A greater proportion of thalassemic children were in IOTN grades 3 and 4, compared to the controls (p<0.001). MSE grades 4 and 5 were significantly (p<0.001) more prevalent in thalassemic children, compared to the controls. Conclusion: There is a high prevalence of Angle's Class II malocclusion in thalassemic children. Majority of these children are categorized in higher grades of IOTN-DHC and TPI-MSE, showing a great severity of malocclusion and high orthodontic treatment needs.

RESUMO Objetivo: Avaliar a prevalência e gravidade da má oclusão em crianças que sofrem de beta-talassemia e mensurar a necessidade de tratamento ortodôntico usando o Índice de Prioridade de Tratamento (IPT) de Grainger e o Índice de Necessidade de Tratamento Ortodôntico (Index of Orthodontic Treatment Need - IOTN) - Componente de Saúde Dental (Dental Health Component - DHC). Métodos: Um estudo transversal foi conduzido com 200 crianças com diagnóstico de beta-talassemia homozigótica dependentes de transfusão e 200 crianças saudáveis em idade escolar, entre 11 e 17 anos. Os dados do IPT e do IOTN-DHC foram documentados para ambos os grupos. A pontuação total do IPT para cada sujeito foi calculada e classificada de acordo com a Estimativa de Severidade da Má oclusão (ESM). O teste t para amostras independentes foi usado para comparar os escores médios de IPT, sobressaliência e sobremordida, entre as crianças saudáveis e as com talassemia. O teste qui-quadrado foi usado para comparar a frequência dos escores do IOTN-DHC, a classificação de Angle e os escores do ESM entre crianças com beta-talassemia e crianças saudáveis. Resultados: A má oclusão mais prevalente foi a Classe I em crianças normais (67,5%) e a Classe II em crianças com beta-talassemia (59%). Os valores médios de sobressaliência e a sobremordida foram significativamente (p< 0,001) maiores em crianças com beta-talassemia do que em crianças saudáveis. Os deslocamentos dentários graves foram 3,5 vezes maiores em crianças com beta-talassemia em comparação com os controles. Uma proporção maior de crianças com beta-talassemia estava nos escores 3 e 4 do IOTN em comparação com os controles (p <0,001). Os escores 4 e 5 de ESM foram significativamente (p< 0,001) mais prevalentes em crianças com beta-talassemia em comparação com os controles. Conclusão: Há uma alta prevalência de má oclusão de Classe II de Angle em crianças com beta-talassemia. A maioria dessas crianças é categorizada em escores superiores de IOTN-DHC e IPT-ESM, mostrando uma grande gravidade de má oclusão e alta necessidade de tratamento ortodôntico.

Association Between Psychosocial Status and Orthodontic Treatment Needs in Indonesian High School Students

Abstract Objective: To determine whether psychosocial status is associated with orthodontic treatment needs in high school students using the Psychosocial Impact of the Dental Aesthetic Questionnaire (PIDAQ) and the Index of Orthodontic Need (IOTN). Material and Methods: This cross-sectional study comprised 95 adolescents, both genders, aged 15-17 years old. PIDAQ was used to assess psychosocial status. The IOTN Aesthetic Component (IOTN-AC) and the IOTN Dental Health Component (DHC) was used to assess treatment needs. Examination of the oral cavity was carried out with the help of the IOTN ruler by observing the MOCDO components: missing teeth, overjet, crossbite, displacement, and overbite. The Chi-square test was used to determine the association of psychosocial status and orthodontic treatment need. The reliability test was carried out by using Cronbach's Alpha test (0.978). Results: There was an association between psychosocial status and orthodontic treatment need based on the IOTN-AC (p=0.001) and between psychosocial status and orthodontic treatment need based on the IOTN-DHC (p=0.140). Conclusion: There is an association between psychosocial status based on the PIDAQ and subjective orthodontic treatment need based on the IOTN-AC, but there is no association between psychosocial status based on the PIDAQ and objective orthodontic treatment need based on the IOTN-DHC in students of SMAN 27 Jakarta.

Influence of social capital on self-perception related to orthodontic treatment need

Aim: To evaluate the influence of social capital on self-perception related to orthodontic treatment need. Methods: A cross-sectional study was conducted with a sample of 578 11-16 years-old adolescents from a city in southern Brazil. Social capital was evaluated using the Social Capital Questionnaire for Adolescent Students (SCQ-AS). Index of Orthodontic Treatment Need (IOTN) assessed malocclusion and self-perception related to orthodontic treatment need. Sociodemographic aspects of adolescents were also evaluated. Individual analyses were performed, relating the study variables to the outcome, estimating the odds ratio with the respective confidence intervals of 95%. The variables with p<0.20 in the individual analyses were tested in the multiple logistic regression models, and those with p<0.10 remained in the model. Results: Social capital did not influence the self-perception related to orthodontic treatment need. Adolescents with high orthodontic needs were 5.35 (CI 95%: 2.68 to 10.65) times more likely to perceived orthodontic treatment need (p <0.05). Crowding and dental absence were associated with self-perception related to orthodontic treatment need (p <0.05). Conclusions: Social capital did not influence the self-perception related to orthodontic treatment need

Correlation between social psychology and personality characteristics and treatment options for adult patients with skeletal malocclusion / 华西口腔医学杂志

OBJECTIVE@#This study aims to explore factors affecting the dental aesthetic social psychology of patients with skeletal malocclusion and to measure the relationship between the objective orthodontic requirements and the subjective treatment requirements of patients. This work provides a reference for doctors to measure patients' orthodontic treatment needs.@*METHODS@#Adult patients with skeletal malocclusion were chosen as the research object. Questionnaire survey was used to analyze factors influencing the psychosocial impact of dental aesthetics questionnaire (PIDAQ), index of orthodontic treatment need (IOTN), and Eysenck personality questionnaire-revised short scale for Chinese (EPQ-RSC). The relationship among PIDAQ, IOTN, EPQ-RSC, and treatment options was also evaluated.@*RESULTS@#Seventy-two valid questionnaires were collected from adult patients with skeletal malocclusion. 1) The PIDAQ scores significantly differed among different occupations (P0.05). People with low educational level were more likely to receive surgery if their psychosocial impacts of dental aes-thetics were serious. 5) The score of psychoticism scale of EPQ-RSC and the educa-tional level had a mutual influence on the PIDAQ score (P<0.01). Moreover, the neuroticism scale and AC self-assessment scores had a mutual influence on the PIDAQ score (P<0.05). However, this study did not find a correlation between personality traits and treatment options.@*CONCLUSIONS@#Many factors, such as personal natural conditions, subjective aesthetic evaluation of teeth, and psychosocial impacts of dental aesthetics, affect patients' treatment options. Personality characteristics can play a certain role in dental aesthetics social psychology.

Prevalence and factors related to malocclusion, normative and perceived orthodontic treatment need among children and adolescents in Bangladesh

ABSTRACT Objective: The purpose of the present study was to assess the prevalence of normative and perceived orthodontic treatment need in schoolchildren and adolescents, related risk factors, and children/parent's aesthetic perception, compared to orthodontist's opinion, in Dhaka city, Bangladesh. Methods: A random sample of 800 schoolchildren aging 11-15 years was selected from different schools in the city of Dhaka, Bangladesh. The Dental Health Component (DHC) and Aesthetic Component (AC) of the Index of Orthodontic Treatment Need (IOTN) were assessed as normative treatment need. The Decayed, Missing, Filled Teeth (DMFT) index was used to record caries experience. Children were interviewed on the perception of orthodontic treatment need. Parents also completed a questionnaire on the perception of their child's orthodontic treatment need, assessed by AC/ IOTN. Results: According to the DHC/IOTN, only 24.7% were in the category of definite need (grade 4-5) for orthodontic treatment. A significant difference was found between the clinician/children and clinician/parents perceived AC score of IOTN (p= 0.0001). Multiple logistic regression showed children with a higher DMFT were significantly more likely to need orthodontic treatment, according to the DHC of IOTN. Conclusion: A low proportion of schoolchildren needs normative orthodontic treatment in the city of Dhaka, Bangladesh. Children with a higher DMFT score were significantly more likely to need orthodontic treatment, according to the DHC of IOTN.

RESUMO Objetivo: o objetivo do presente estudo foi avaliar a prevalência de necessidade real e percebida de tratamento ortodôntico em crianças e adolescentes em idade escolar, bem como de fatores de risco relacionados, e comparar a percepção estética das crianças e responsáveis com a percepção de ortodontistas na cidade de Dhaka, Bangladesh. Métodos: uma amostra aleatória composta por 800 crianças, com idades entre 11 e 15 anos, foi selecionada em diferentes escolas da cidade de Dhaka, Bangladesh. Para avaliação da necessidade real de tratamento, utilizou-se o Dental Health Component (DHC) e o Aesthetic Component (AC) do Index of Orthodontic Treatment Need (IOTN). O índice de Dentes Cariados, Perdidos e Obturados (CPO-D) foi usado para registrar a prevalência de cáries dentárias. As crianças foram entrevistadas sobre sua percepção da necessidade de tratamento ortodôntico, e os pais também responderam a um questionário sobre a percepção da necessidade de tratamento ortodôntico de seus filhos, avaliada pelo AC do IOTN. Resultados: de acordo com o DHC, apenas 24,7% das crianças foram alocadas na categoria de necessidade real (notas 4-5) de tratamento ortodôntico. As pontuações no AC foram significativamente diferentes entre os ortodontistas, as crianças e os responsáveis (p= 0,0001). A análise da regressão múltipla mostrou que as crianças com maiores pontuações no CPO-D tinham chance significativamente maior de precisar de tratamento ortodôntico, segundo o DHC. Conclusão: um número reduzido de crianças em idade escolar necessita realmente de tratamento ortodôntico em Dakha, Bangladesh. Além disso, as crianças com maior CPO-D apresentaram chance significativamente maior de precisar de tratamento ortodôntico, segundo o DHC.

The relationship between oral health-related quality of life, the need for orthodontic treatment and bullying, among Brazilian teenagers

ABSTRACT Introduction: Orthodontic treatment aims at oral health and restoration of function as main objectives, however, psychological and social effects end up being the main reason for the demand for treatment. Objective: To determine the association between the oral health-related quality of life (OHRQoL), the need for orthodontic treatment and bullying among Brazilian teenagers. Methods: This was a cross-sectional epidemiological study. To assess the malocclusion, the Dental Aesthetic Index was used. And the Oral Health Impact Profile-14 was used to analyze the OHRQoL. The Kidscape questionnaire was used to investigate cases of bullying. The following variables were also included: previous orthodontic treatment and a desire to fix the teeth to improve one's appearance. Multivariate analysis was performed using logistic regression considering the poor OHRQoL as a response variable. Results: 815 teenagers participated in the study. There was a statistically significant association between oral health-related quality of life and the variables: previous orthodontic treatment (p= 0.0270), desire to fix the teeth (p< 0.0001), sex (p= 0.0309), history of being a victim of bullying (p< 0.0001), frequency of bullying episodes (p= 0.0170), and consequences of bullying (p< 0.0001). The following were considered as risk factors for poor OHRQoL: lack of previous orthodontic treatment (OR = 2.191) and negative consequences of bullying (OR = 3.042). Conclusion: The need for orthodontic treatment was not associated with the OHRQoL; however, bullying and previous orthodontic treatment had a statistically significant association with this variable.

RESUMO Introdução: o tratamento ortodôntico visa à saúde bucal e ao reestabelecimento da função como objetivo final; no entanto, os efeitos psicológicos e sociais acabam sendo o principal motivo da procura pelo tratamento. Objetivo: determinar a associação entre a qualidade de vida relacionada à saúde bucal (QVRSB), a necessidade de tratamento ortodôntico e o bullying entre os adolescentes. Métodos: trata-se de um estudo epidemiológico transversal. Para avaliar a má oclusão, foi utilizado o Dental Aesthetic Index. O instrumento Oral Health Impact Profile-14 foi utilizado para analisar a QVRSB. O questionário Kidscape foi utilizado para verificar os casos de bullying. Também foram incluídas as variáveis: tratamento ortodôntico prévio e desejo de corrigir os dentes para melhorar a aparência. A análise multivariada foi realizada por meio de regressão logística, considerando-se a qualidade de vida ruim como variável resposta. Resultados: 815 adolescentes participaram da pesquisa. Houve associação, estatisticamente significativa, entre a qualidade de vida relacionada à saúde bucal e as variáveis: tratamento ortodôntico prévio (p= 0,0270), desejo de corrigir os dentes (p< 0,0001), sexo (p= 0,0309), bullying (p< 0,0001), frequência de episódios de bullying (p= 0,0170) e consequências do bullying (p< 0,0001). Foram considerados como fatores de risco para uma QVRSB ruim os adolescentes que não realizaram tratamento ortodôntico prévio a esse estudo (OR= 2,191) e aqueles que revelaram consequências negativas relacionadas aos episódios de bullying (OR= 3,042). Conclusão: a necessidade de tratamento ortodôntico não foi associada à qualidade de vida relacionada à saúde bucal, já o bullying e o tratamento ortodôntico prévio tiveram associação estatisticamente significativa com essa variável.

RESUMEN La Encuesta Demográfica de Salud Familiar (ENDES) es una encuesta nacional de base poblacional con representatividad a nivel departamental y área de residencia, constituyéndose en una fuente de información del estado de salud de la población peruana. Con el objetivo de estandarizar su procesamiento y posterior reutilización por parte de la comunidad académica y otros actores interesados; documentamos el código para la manipulación, análisis y visualización de datos del cuestionario de salud de la ENDES 2017, mediante un ejemplo sobre prevalencia de hipertensión arterial y obesidad, utilizando el entorno y lenguaje de programación estadístico R. Se presenta y detalla secuencialmente el código en R, así como, el sustento teórico de la estructura de la encuesta para la manipulación de las bases de datos, considerando que la compleja estructura de la ENDES podría ser una potencial barrera que enfrentan los investigadores. Finalmente, este ejemplo puede servir de base para que se generen mayores estudios basados en la ENDES que sean relevantes para la toma de decisiones en salud pública.

ABSTRACT The Demographic and Family Health Survey (ENDES, in Spanish) is a national population-based survey with representation at the departmental level and area of residence, constituting a source of information on the health status of the Peruvian population. In order to standardize its processing and subsequent reuse by the academic community and other stakeholders, we documented the code for the manipulation, analysis, and visualization of data from the ENDES 2017 health questionnaire, through an example on the prevalence of hypertension and obesity, using the R statistical programming environment and language. The R code is presented and detailed sequentially, as well as the theoretical support of the survey structure for the manipulation of databases, considering that the complex structure of the ENDES could be a potential barrier faced by researchers. Finally, this example can serve as a basis for generating further studies based on the ENDES that are relevant to public health decision-making.

Objetivos: analisar a associação entre a auto percepção e a necessidade clínica de tratamento ortodôntico e investigar a relação entre a necessidade de tratamento ortodôntico e o impacto nas atividades diárias comer, sorrir e falar, em adolescentes. Sujeitos e método: estudo transversal com 1.630 escolares com idade entre 15 e 19 anos, de 36 municípios do estado do Rio Grande do Sul. Os instrumentos utilizados para determinar a necessidade de tratamento ortodôntico foram o Índice de Estética Dental (DAI) e o Componente Estético (AC) do Índice de Necessidade de Tratamento Ortodôntico (IOTN). Os dados foram analisados com o programa SPSS 21.0, utilizando-se os testes Qui-Quadrado de Pearson ou Qui-Quadrado de tendência linear e a regressão de Poisson. O nível de significância adotado foi de 5%. Resultados: observou-se associação positiva entre o IOTN e o DAI. A proporção de sujeitos que perceberam a necessidade de tratamento ortodôntico aumentou com a recomendação feita pelo dentista. Entretanto, a maioria dos adolescentes entrevistados não percebia necessidade de tratamento ortodôntico. Após o ajuste, observou-se associação entre a maloclusão e o desempenho da atividade diária sorrir (RP = 2,03) e o sexo dos escolares (RP = 1,28). Também se observou associação entre o sexo dos adolescentes (RP = 1,23), a escolaridade do pai (RP = 1,21) e o impacto na atividade comer. A atividade diária de falar estava associada com a escolaridade do pai (RP = 2,11). Conclusão: existe associação entre a auto percepção de tratamento ortodôntico e a necessidade clínica. A maloclusão impacta a atividade sorrir entre os adolescentes, entretanto, o mesmo não ocorre com as atividades comer e falar. (AU)

Objective: to analyze the association between self- -perception and clinical need for orthodontic treatment, and to investigate the relationship between the need for orthodontic treatment and the impact on daily activities of eating, smiling, and speaking, in adolescents. Subjects and method: cross-sectional study with 1630 school children aged 15 through 19 years from 36 cities of the state of Rio Grande do Sul, Brazil. The instruments used to determine the need for orthodontic treatment were the Dental Aesthetic Index (DAI) and the Aesthetic Component (AC) of the Index of Orthodontic Treatment Need (IOTN). The data were analyzed with the SPSS 21.0 software using Pearson's chi-square or linear trend chi-square tests and Poisson regression. The significance level was 5%. Results: there was a positive association between IOTN and DAI. The proportion of subjects who perceived the need for orthodontic treatment increased with the recommendation from the dentist. However, most of the adolescents interviewed did not perceive the need for orthodontic treatment. After adjustment, there was an association of malocclusion with the performance of the daily activity of smiling (PR = 2.03) and the gender of school children (PR = 1.28). An association was also observed for the gender of adolescents (PR = 1.23) and paternal level of education (PR = 1.21) with the daily activity of eating. The daily activity of speaking was associated with the paternal level of education (PR = 2.11). Conclusion: there is an association between self-perception of orthodontic treatment and the clinical need. Malocclusion affects the activity of smiling among adolescents, but the same does not occur with the activities of eating and speaking. (AU)
