ABSTRACT
Abstract The aim of this study was to evaluate the convergence between the domains of the Autoquestionnaire Qualité de Vie Enfant image (AUQUEI) and the Child Perceptions Questionnaire (CPQ8-10) in the mixed dentition. A sample of 676 children aged 8 to 10 years responded to the health-related quality of life (HRQoL) and oral health-related quality of life (OHRQoL) questionnaires using the AUQUEI and the CPQ8-10, respectively. Clinical (dental caries and malocclusion) and socioeconomic variables were assessed. The validity of convergence between scores (total and per domain) of the two instruments was assessed by Spearman correlation analysis, considering that non-zero coefficient values represented a correlation between scores. The median was calculated to compare the scores of each questionnaire relative to the variables, and the nonparametric Mann-Whitney test was applied to determine statistically significant differences between the categories. A weak significant correlation (between 0.30 and 0.50) was observed between the domains and the total scores of instruments (p < 0.05), except for the leisure domain (p > 0.05). Participants with a lower family income had worse HRQoL (p < 0.05), and those with caries and malocclusion experience had worse OHRQoL (p < 0.05). In conclusion, the AUQUEI and CPQ8-10 instruments showed a weak correlation. Income and clinical variables had a negative impact on the AUQUEI and CPQ8-10, respectively.
ABSTRACT
ABSTRACT Objective: To determine the prevalence of the need for orthodontic treatment, anxiety, and probable sleep bruxism and its association in adolescents. Material and Methods: A cross-sectional study was conducted with 294 adolescents aged between 11 and 16 years. Orthodontic treatment need was determined using the Dental Health Component of the Index of Orthodontic Treatment Needs (IOTN-DHC). Anxiety symptoms were assessed using the Brazilian version of the Multidimensional Anxiety Scale for Children (MASC). The probable sleep bruxism was identified based on the American Academy of Sleep Medicine (AASM) questionnaire. Descriptive data analyses were performed. Simple logistic regression models were applied between each independent variable and the outcome (anxiety score). Variables with p<0.20 in the individual (raw) analyses were studied in a multiple logistic regression model, with p≤0.05 remaining in the final model. Based on the regression models, the prevalence ratios were estimated with the respective 95% confidence intervals. Results: 68.7% of the adolescents had probable sleep bruxism, and 35.4% had a moderate or severe normative need for orthodontic treatment. Adolescents aged up to 12 years (OR=1.82; CI: 1.10-3.02), females (OR=2.67; CI: 1.64-4.34), and with a moderate or severe need for orthodontic treatment according to the IOTN-DHC (OR=1.76; CI: 1.06-2.90), are more likely to have a higher anxiety score. The prevalence of adolescents with a moderate or severe need for normative orthodontic treatment by the IOTN-DHC is 35.4% (95%CI: 29.9-40.8%), while the perceived need for treatment by the IOTN-AC is 14.0% (95%CI: 10.0-17.9%). Adolescents with a high degree of anxiety were more likely to have probable sleep bruxism (OR=3.64; CI: 1.06-12.50). Conclusion: Female adolescents up to 12 years of age and with a moderate or severe need for orthodontic treatment are more likely to have higher levels of anxiety; adolescents with a high degree of anxiety are more likely to have probable sleep bruxism.
ABSTRACT
Abstract This study aimed to make a longitudinal analysis of interexaminer calibration reproducibility in diagnosing dental caries in posterior teeth, by examiners without previous experience in epidemiological studies. A group of 11 inexperienced examiners underwent theoretical-practical training and calibration assessments, assisted by a standard examiner. An examiner who did not participate directly in the research selected 5-year-old children with and without caries. The D3 diagnostic threshold was used to evaluate dental caries, based on the World Health Organization (WHO) criteria. The initial calibration (baseline) was performed after the theoretical-practical training session, and consisted of examining 20 children; the second calibration occurred three months later, and involved evaluating another 18 children. The interexaminer agreement was obtained by kappa statistics, and by overall percentage agreement. The paired t-test was applied to compare the values for kappa means and overall percentage agreement between the time points studied. At baseline, the values for kappa (> 0.81) and overall percentage agreement (> 95.63%) were considered high. At the 3-month calibration assessment, all the examiners showed some decrease in both kappa (p < 0.0001) and overall percentage agreement (p = 0.0102). The calibration process currently proposed by the WHO is effective. However, reproducibility was not maintained over time for inexperienced examiners evaluating the posterior teeth of 5-year-old children, under epidemiological conditions.
ABSTRACT
Abstract Objective: To associate the OHRQoL and HRQoL in mixed dentition children with the influence on age range, socioeconomic and clinical variables. Material and Methods: A cross-sectional study was carried out with 1,240 children between 6 and 12 years of age. HRQoL was assessed by the Quality of Life Assessment Scale, considered an outcome variable. OHRQoL was determined using specific questionnaires related to the age group: Oral Health Impact Scale in Early Childhood, Child Perceptions Questionnaire for 8 to 10 years, and 11 to 12 years. Dental caries and malocclusion were diagnosed. The socioeconomic class was evaluated. A multiple negative binomial regression analysis was used to test the relationship between HRQoL, OHRQoL scores and socioeconomic and clinical variables. Correlation analyses were performed between the total HRQoL and OHRQoL, with a significance level of 5%. Results: The HRQoL is inversely related to the impact of OHRQoL (p<0.05), modulated by the age group. There was a significant weak negative correlation between the HRQoL scores and the impact of OHRQoL (p<0.05). Conclusion: The OHRQoL impacts the HRQoL, modulated by the age group and with minor influence from socioeconomic and clinical variables (AU).

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).

ABSTRACT
Aim: To evaluate orthodontists' knowledge and clinical practices regarding the treatment of patients with HIV/AIDS. Methods: Cross-sectional study performed with 655 Brazilian orthodontists based on a previously calculated sample size. Self-administered questionnaires were sent to orthodontists to collect information on knowledge and clinical conduct regarding the care of patients with HIV/AIDS. The study evaluated the awareness of possible risk factors for contamination, oral manifestations of HIV, need for more information on the care of HIV-positive patients, whether orthodontic treatment is indicated in HIV-positive patients, and whether they had knowingly performed orthodontic treatment in HIV-positive patients. Simple regression models were adjusted, and crude Odds Ratios estimated the associations with 95% confidence intervals. The variables with P < 0.20 in the crude analysis were tested in multiple logistic regression models, and those with P ≤ 0.05 were maintained in the final model. Magnitudes were estimated by adjusted Odds Ratios values, with 95% confidence intervals. Results: Orthodontists who were aware of the oral manifestations of HIV/AIDS, those having work experience of more than 20 years, and those who believed that orthodontic treatment could be indicated for these patients were 3.30 (1.79-6.10), 2.74 (1.36-5.52) and 1.92 (1.13-3.24) times more likely to perform orthodontic treatment in HIV-positive patients, respectively. Most orthodontists (92.9%) reported they needed to obtain more information about orthodontic care in patients with HIV/AIDS. Conclusion: Although orthodontists reported feeling able and qualified to provide dental care to patients with HIV/AIDS, gaps in their knowledge need to be addressed with further training

Abstract The aim of this study was to evaluate the impact of malocclusion severity on the oral health-related quality of life (OHRQoL) of non-white adolescents. A cross-sectional study was conducted with 585 non-white Brazilian adolescents (12-15 years). The Dental Aesthetic Index (DAI) was used for the clinical assessment of malocclusion and Oral Health Impact Profile (OHIP-14) on OHRQoL. Deep bite and transverse occlusal relationships were assessed in association with the DAI. The adolescents with DAI 3 and 4 were distributed into 4 groups: G1 - individuals without transverse occlusal relationships or deep bite; G2 - individuals with only posterior crossbite; G3 - individuals with only deep bite; and G4 - individuals with Brodie bite. The backward stepwise procedure was used to select variables on each level, eliminating variables with a p≤0.20. From the logistic regression analyses, the adjusted odds ratios were estimated with the respective 95% confidence intervals. The adolescents with severe malocclusion divided into the G2, G3 and G4 showed p-value of 0.0501, 0.1475, and 0.5407, respectively, but did not remain in the final model. Malocclusion severity had no impact on the OHRQoL of non-white adolescents.
Resumo O objetivo deste estudo foi avaliar o impacto da severidade da má oclusão na qualidade de vida relacionada à saúde bucal (OHRQoL) de adolescentes não brancos. Estudo transversal foi realizado com 585 adolescentes brasileiros não brancos (12-15 anos). O Índice de Estética Dental (DAI) foi utilizado para a avaliação clínica da má oclusão e o Oral Health Impact Profile (OHIP-14) na OHRQoL. A sobremordida profunda e as relações oclusais transversais foram avaliadas em associação com o DAI. Os adolescentes com DAI 3 e 4 foram divididos em 4 grupos: G1 - indivíduos com relação transversal normal ou com ausência de sobremordida; G2 - indivíduos com mordida cruzada posterior; G3 - indivíduos com sobremordida profunda; e, G4 - indivíduos com mordida em Brodie. O modelo final estimou as variáveis selecionadas após o ajuste para aquelas que permaneceram no modelo multivariado em níveis iguais e superiores. A partir das análises de regressão logística, os odds ratios foram ajustados e estimados com os respectivos intervalos de confiança de 95%. Os adolescentes com má oclusão severa divididos em G2, G3 e G4 mostraram um p-valor de 0.0501, 0.1475, e 0.5407, respectivamente, mas não permaneceram no modelo final. A severidade da má oclusão não teve impacto na OHRQoL de adolescentes não brancos.

Abstract The purpose of this in vitro study was to evaluate the force decrease of different elastomeric chains after different times: initial, 10 minutes, 1 day, 28 days and after mechanical brushing. Twenty orthodontic elastomeric chains segments were utilized for each commercial brand. Initially, the elastomeric chain of 15mm long were immediate stretched up to 20 mm in an Instron and the force was measured in gf. After all specimens were placed stretched on rectangular acrylic jigs with distance of 20 mm, immersed in deionized water at 37oC for 10 minutes and the force (gf) was measured again. Five test measurements of remaining force were made at the following time intervals: initial, 10 minutes, 1 day, 28 days and mechanical brushing. After 28 days, the acrylic plates with the specimens were adapted in the mechanical brushing machines (MSCT 3) and the elastomeric chains were submitted to mechanical brushing and the force (gf) measure again. The force (gf) was submitted to mixed-model ANOVA and Sidak post-hoc test (α=0.05). A statistically significant reduction in the force was found for all orthodontic elastomeric chain types after 1 day, 28 days and mechanical brushing (p<0.05). Morelli and 3M Unitek elastomeric chains showed significantly higher force than Abzil and GAC (p<0.05) after 1 day, 28 days and mechanical brushing. In conclusion, the force delivered by all elastomeric chains decayed rapidly over time. Morelli and 3M Unitek elastomeric chains consistently had a significantly greater force after mechanic brushing, while GAC the lowest.

Introdução O desenvolvimento do complexo craniofacial resulta da interação de fatores genéticos e ambientais. Dentre as ocorrências que podem afetar esse desenvolvimento, estão as odontológicas. A cárie dentária e a má oclusão são de etiologia multifatorial e atingem grande parte da população, podendo impactar a qualidade de vida. Objetivo O objetivo deste estudo foi avaliar o impacto de fatores clínicos, funcionais e sociais na qualidade de vida relacionada a saúde bucal de crianças e suas famílias. Material e método A amostra consistiu de 753 crianças matriculadas nas escolas públicas da cidade de Araraquara-SP. Foram realizados exames bucais para avaliar a ocorrência cárie dentária (ceo-d e CPO-D) e a má oclusão (Foster, Hamilton) e aplicado um questionário socioeconômico aos pais, além do questionário para avaliação da qualidade de vida relacionada a saúde bucal (ECOHIS). Os dados foram avaliados por meio de análise bivariada e, em seguida, pelo modelo de regressão logística múltipla, considerando o nível de significância de 5%. Resultado A condição social, além das variáveis clínicas de cárie dentaria e trauma dental, apresentou associação com o impacto negativo na qualidade de vida relacionada a saúde bucal nas três sessões do questionário: criança, pais e geral, respectivamente. Conclusão A experiência da cárie dentária, o nível socioeconômico e o trauma dental foram variáveis preditoras para o impacto negativo na qualidade de vida relacionada a saúde bucal de crianças e suas famílias. Os hábitos estão mais relacionados ao índice ceo-d e ao nível socioeconômico do que com a má oclusão.
Introduction The development of the craniofacial complex results from the interaction of genetic and environmental factors. Dental caries and malocclusion have a multifactorial etiology and affect a large part of the population, which may impact the quality of life. Objective The aim of this study was to evaluate the impact of clinical, functional and social factors on oral health-related quality of life of children and their families. Material and method The sample consisted of 753 children enrolled in public schools in the city of Araraquara-SP. Oral examinations were performed to assess dental caries (dmft and DMFT) and malocclusion (Foster, Hamilton) and a socioeconomic questionnaire was administered to the parents, in addition to the quality assessment questionnaire. health-related life expectancy (ECOHIS). Data were evaluated by bivariate analysis and then by multiple logistic regression model, considering the significance level of 5%. Result Social condition, besides the clinical variables dental caries and dental trauma were associated with the negative impact on oral health-related quality of life in the three questionnaire sessions, child, parent and general respectively. Conclusion The experience of dental caries, socioeconomic status and dental trauma were predictive variables for the negative impact on oral health-related quality of life of children and their families. Habits seem to be more related to the dmft index and socioeconomic level than to malocclusion.

ABSTRACT Objective: To evaluate the influence of dental trauma on oral health-related quality of life (OHRQoL) of children and their families. Methods: A total of 571 children aged five years were randomly selected at public schools. Trauma was clinically evaluated in accordance with the Andreasen classification. Caries experience in the anterior region and increased overjet were determined according to the World Health Organization criteria. The Early Childhood Oral Health Impact Scale (ECOHIS) was answered by the parents and used to evaluate OHRQoL. In addition, this questionnaire has aspects related to socioeconomic status. Simple logistic regression was performed, and the raw Odds Ratios with the respective 95% confidence intervals (95%CI) were estimated. The variables with p<0.20 were tested in multiple logistic regression models, and those with p≤0.05 remained in the model and the adjusted odds ratio with respective 95%CI was estimated. Results: Income showed a magnitude of association of 1.56 and 2.70 with the OHRQoL of children and families, respectively. The avulsion variable showed 9.65- and 8.25-times greater chance of influencing the OHRQoL of children and families, respectively. The experience of caries showed 3.80- and 2.42-times greater chance of influencing the OHRQoL of children and families, respectively. Conclusions: Dental trauma did not influence OHRQoL of children and their families negatively. However, avulsion and caries experience in low-income families was associated with a negative perception of OHRQoL.
RESUMO Objetivo: Avaliar a influência do traumatismo dentário na qualidade de vida relacionada à saúde bucal (QVRSB) de crianças e suas famílias. Métodos: 571 crianças de 5 anos de idade foram aleatoriamente selecionadas de escolas públicas. O trauma foi avaliado clinicamente de acordo com a classificação de Andreasen. A experiência de cárie na região anterior e a presença de overjet foram determinadas com base nos critérios da Organização Mundial da Saúde. A versão brasileira do questionário ECOHIS (Escala de Impacto na Saúde Oral na Primeira Infância) avaliou a QVRSB e foi respondida pelos pais; além disso, foram avaliados aspectos socioeconômicos. Realizou-se uma regressão logística simples, bem como as razões de chances brutas com os respectivos intervalos de confiança de 95%. As variáveis com p <0,20 foram testadas nos modelos de regressão logística múltipla, e aquelas com p≤0,05 permaneceram no modelo. Resultados: A renda mostrou uma magnitude de associação de 1,56 e 2,70 com a QVRSB das crianças e famílias, respectivamente. A variável avulsão apresentou chance 9,65 e 8,25 vezes maior de influenciar a QVRSB de crianças e famílias, respectivamente. A experiência de cárie mostrou chance 3,80 e 2,42 vezes maior de influenciar a QVRSB de crianças e famílias, respectivamente. Conclusões: O trauma dental não influenciou negativamente a QVRSB das crianças e suas famílias. Entretanto, especificamente a avulsão, e a experiência de cárie nos dentes anteriores em famílias de baixa renda estiveram associadas a uma percepção negativa da QVRSB.

ABSTRACT Objective: To analyze the difference in the on-line searches for terms related to hand hygiene during the COVID-19 pandemic in developed and middle-income countries. Material and Methods: The cross-sectional study analyzed the digital data through the Google Trends website to obtain the variation of the relative search volume (RSV) through the terms "alcohol gel" and "handwashing." According to socio-economic development, the countries were divided into two groups: countries from different continents and hemispheres, with more than 15 million inhabitants, with more than 50% of the population with access to the Internet network and over 1,000 confirmed cases of infected with COVID-19. The paired t-test was applied to compare the means. The significance value adopted was p<0.010. Results: The searches related to the term "hand washing" were more significant when compared to the term "alcohol gel," and the term "alcohol gel" presented a higher average volume of research in developed countries (p<0.010). The developed countries had a higher average relative volume of research than middle-income countries (p<0.010). Developed countries sought more for the term "alcohol gel," and the term "hand washing" showed no difference in the volume of research about the country's socio-economic aspect. Conclusion: Developed countries have a higher volume of search for hand hygiene terms. The middle-income countries must create proposals for raising awareness outside the on-line environment so that this information reaches the entire population during the pandemic.

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.

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

Introduction: Although many studies are being carried out with sleep bruxism, the literature points to a lack of studies with methodological quality in children. Objective: To evaluate the behavioral and clinical aspects associated with probable sleep bruxism in early childhood. Material and method: A cross-sectional observational study carried out with 371 children between 4 and 6 years of age. Parents answered a questionnaire with aspects related to their children's sleep behavior. Among the clinical characteristics, the presence of lip sealing, clicking, teeth marks on the jugal mucosa, and the side of the tongue was evaluated. Tooth wear was assessed using the BEWE index criteria. Simple logistic regression models were adjusted for each independent variable, estimating the gross odds ratios with the respective 95% confidence intervals. Variables with P <0.20 in the individual analyzes were adjusted in a multiple logistic regression model, with those with P ≤ 0.05 remaining in the model. Result: 42.4% of parents reported that their children gritted their teeth while sleeping. Children who showed wear on their teeth were 1.53 times more likely to grind their teeth. There was no significant association with the other variables analyzed (P > 0.05). Conclusion: Behavioral aspects were not associated with probable sleep bruxism. Among the clinical characteristics evaluated, tooth wear showed an association, which may indicate the probable bruxism of sleep in early childhood.
Introdução: Embora muitos estudos estejam sendo realizados com o bruxismo do sono, a literatura aponta uma carência de estudos com qualidade metodológica em crianças. Objetivo: Avaliar os aspectos comportamentais e clínicos associados ao provável bruxismo do sono na primeira infância. Material e método: Estudo observacional transversal realizado com 371 crianças entre 4 e 6 anos de idade. Os pais responderam a um questionário com aspectos relacionados ao comportamento do sono de seus filhos. Entre as características clínicas, foram avaliados a presença de selamento labial, estalidos, marcas dos dentes na mucosa julgal e na lateral da língua. O desgaste dentário foi avaliado por meio dos critérios do índice de BEWE. Foram ajustados modelos de regressão logística simples, para cada variável independente, estimando-se os odds ratios brutos com os respectivos intervalos de 95% de confiança. As variáveis com P< 0.20 nas análises individuais foram ajustadas em um modelo de regressão logística múltipla, permanecendo no modelo aquelas com P ≤ 0.05. Resultado: 42.4% dos pais relataram que seus filhos rangiam os dentes enquanto dormiam. Crianças que apresentaram desgastes nos dentes, tinham 1.53 vezes mais chances de ranger os dentes. Não houve associação significativa com as demais variáveis analisadas (P> 0.05). Conclusão: Aspectos comportamentais não apresentaram associação com o provável bruxismo do sono. Entre as características clínicas avaliadas, o desgaste dentário apresentou associação, podendo ser um indicador para o provável bruxismo do sono na primeira infância.

Abstract This study to evaluate the effects of different hydrofluoric acid (HF) concentrations and thermal cycling on the shear bond strength (SBS) of brackets to ceramic. Cylinders of ceramic were divided into 10 groups (n=15), according to HF concentrations: 1-1%;2-2.5%;3-5%;4-7.5%;5-10% (storage 24 h); 6-1%;7-2.5%;8-5%;9-7.5%; and, 10-10% (thermal cycling). All cylinders were etched for 60s and received one layer of silane. Metallic brackets were bonded to the cylinders using Transbond-XT, light activated for 40 s, using a LED (Radii Plus) and stored in deionized water at 37o C for 24h. The groups 6 to 10 were submitted to thermal cycling (7,000 cycles - 5o/55oC). SBS was performed in an Instron at crosshead speed of 1.0 mm/min. Data were submitted to two-way ANOVA and Tukey's post-hoc test (α=0.05). The Adhesive Remaining Index (ARI) was evaluated at 40x magnification. The different HF acid concentrations influenced on the SBS of the brackets to ceramic (p<0.05). The thermal cycling decreased the SBS of the brackets to ceramic for all acid concentrations (p<0.05). The ARI showed a predominance of scores 0 for all groups, with an increase in scores 1, 2 and 3 for the group storage for 24 h. In conclusion, the different HF acid concentrations 5.0%, 7.5% and 10% influenced on the SBS of brackets to ceramic. The thermal cycling decreased significantly the SBS of brackets to ceramic.

Abstract Introduction This cross-sectional study aimed to associate the normative cephalometric results of mandibular retrognathism treatment with patient perception on the esthetic improvement of facial profile. Objective this cross-sectional study aimed to associate the normative cephalometric results of mandibular retrognathism treatment with patient perception on the esthetic improvement of facial profile. Material and method The normative cephalometric results were obtained from lateral cephalometric radiographs of a sample of 24 Class II malocclusion patients in the pubertal growth spurt. Such patients were treated with a mandibular advancement device and evaluated by comparing pre- and post-treatment variables. The same radiographs were used to produce standardized black silhouettes that were randomly arranged. Patients were instructed to choose their preferred profile and indicate the changes perceived using a 7-point Likert scale. The data were compared with cephalometric results using a mixed-model methodology for time-repeated measures, Student's t-test, and t-test for heterogeneous variances, at 5% significance level. Result A rate of 75% of patients preferred post-treatment silhouettes and changes were perceived regardless of the choice of either pre- or post-treatment profile. There was no significant difference between the cephalometric variables of the tracings that produced the silhouettes considered better or worse after the evaluation. Conclusion There was no association between the cephalometric results after treatment and the perception of esthetic improvement by patients treated for mandibular retrognathia.

Abstract Satisfaction with dental aesthetics is a subjective indicator used in epidemiological studies and is related to health behaviours. Little is known about the factors that influence this indicator, particularly among adolescents who live in a situation of social vulnerability. The aim of this study was to investigate the relationship between malocclusion and dental appearance in underprivileged Brazilian adolescents. This analytical cross-sectional study was conducted in Piracicaba, Brazil, and evaluated 884 adolescents from 13 to 19 years of age. The dependent variable was satisfaction with dental appearance, and the independent variables were classified as individual (components of the Dental Aesthetic Index - DAI, sex and age) and contextual (social exclusion index). For statistical analysis, multilevel regression models were estimated. The individual variables were considered Level 1, and the contextual variable was considered Level 2, with a level of significance of 5%. The mean age of the adolescents was 15.3 years. Female adolescents more frequently affirmed that they were satisfied with their dental appearance than did male individuals. There was an increase in dissatisfaction with oral health with the increase in anterior maxillary overjet, midline diastema, larger anterior irregularity in the maxilla, larger anterior irregularity in the mandible, anterior open bite and antero-posterior molar relation. Satisfaction with dental appearance was associated with individual factors such as sex and DAI components.

Objective: This study was designed to evaluate the skeletal, dental and soft tissue effects of mandibular deficiency treatment with the mandibular protraction appliance (MPA) using 12 factors of the Ricketts analysis. Material and method: This cross-sectional retrospective study sample consisted of a group (n = 27), with Class II malocclusion, convex facial profile, increased horizontal trespass and mandibular deficiency, with initial mean age of 12.27 and final of 15.18 years, treated with fixed appliance combined with the MPA, in an average time of 2.9 years. Initial and final radiographs were investigated using Ricketts analysis. The dependent t-test was used to compare the initial and final phases of the MPA group, with a significance level of 5%. Result: Statistically significant differences were observed for dental changes such as retrusion (p=0.000) and palatal inclination of the maxillary incisors (p=0.000); protrusion (p=0.000) and buccal inclination of the mandibular incisors (p=0.000); increased interincisal angle (p=0.002) and improved molar ratio (p=0.003). There was also a restriction of the anterior displacement of the maxilla (p=0.000) and a decrease in the mandibular plane angle (p=0.024). The variable inferior labial protrusion with significance (p=0.000), reiterated the improvement in the profile. Conclusion: The effects of MPA on correction of malocclusion Class II, verified by Ricketts analysis occurred predominantly by dentoalveolar changes, decrease in the Mandibular Plane Angle, and restriction of anterior displacement of the maxilla, which contributed to the improvement in the patient's profile.
Objetivo: Este estudo analisou as alterações dentárias, esqueléticas e tegumentares promovidas pelo Aparelho de Protração Mandibular (APM) por meio da análise de Ricketts. Material e método: A amostra contou com 27 pacientes (14 meninas e 13 meninos) com má oclusão de Classe II, perfil facial convexo, trespasse horizontal aumentado e deficiência mandibular, com idade média inicial de 12,27 e final de 15,18 anos, tratados com aparelho fixo combinado com o APM. A comparação das telerradiografias iniciais (T1) e finais (T2) foi realizada pelo teste t dependente, com nível de significância de 5%. Resultado: Observou-se diferença estatisticamente significante para a retrusão (p=0.000) e lingualização dos incisivos superiores (p=0.000), protrusão (p=0.000) e vestibularização dos incisivos inferiores (p=0.000), aumento do ângulo interincisivos (p=0.002), melhora da relação molar (p=0.003), restrição do deslocamento anterior da maxila (p=0.000), diminuição do ângulo do plano mandibular (p=0.024) e melhora do perfil facial (p=0.000). Conclusão: O APM promoveu alterações dentoalveolares, observadas principalmente pela diminuição do ângulo do plano mandibular e restrição do deslocamento para anterior da maxila que contribuíram para a melhora do perfil do paciente.
