RESUMO

OBJECTIVE: The aim of the present study was to assess the impact of orthodontic retainers on oral health-related quality of life (OHRQoL) in the short and long terms after orthodontic treatment. METHODS: Data from 45 patients up to three years after orthodontic treatment (T0) were analyzed. Patients were reassessed four years (T1) after T0. OHRQoL was measured using the OHIP-14 (Oral Health Impact Profile-14) questionnaire. The presence of a fixed retainer in the upper and/or lower arches, sex, and age were the predictive variables evaluated at T0 and T1. The occurrence of retainer fracture at T0 was clinically evaluated. Due to the COVID-19 pandemic, clinical examination on T1 was not possible, so the OHIP-14 and the self-perception of changes in teeth position and fracture of retainers were examined using an on-line questionnaire. RESULTS: At the initial examination, the presence of upper retainers had a negative impact on quality of life (p=0.018). The OHIP-14 value increased significantly from T0 to T1 (p=0.014), regardless of the presence of retainers. The fracture or debonding of the retainer reported by the patient was the only variable that had a negative impact on OHRQoL (p=0.05). CONCLUSION: The use of fixed upper retainers suggests a negative impact on the quality of life of the orthodontic patient after the end of orthodontic treatment. This impact, however, is negligible in the long term, except when associated with fracture or debonding. This study emphasizes the need for continuous follow-up of orthodontic patients during the retention period.

RESUMO Objetivo: O objetivo deste estudo foi avaliar o impacto das contenções ortodônticas na qualidade de vida relacionada à saúde bucal (QVRSB) em curto e longo prazos após o tratamento ortodôntico. Métodos: Foram analisados dados de 45 pacientes até três anos após o tratamento ortodôntico (T0). Os pacientes foram reavaliados quatro anos (T1) após T0. A QVRSB foi mensurada usando o questionário OHIP-14 (Oral Health Impact Profile-14). A presença da contenção fixa nas arcadas superior e/ou inferior, o sexo e a idade foram as variáveis preditoras em T0 e T1. A ocorrência de quebra da contenção em T0 foi avaliada clinicamente. Em razão da pandemia da COVID-19, não foi possível o exame clínico em T1; assim, a autopercepção das alterações na posição dos dentes e a quebra ou descolagem das contenções foram registradas por meio de um questionário online. Resultados: No exame inicial, a presença da contenção superior apresentou um impacto negativo na qualidade de vida (p=0,018). Em T1, o valor de OHIP-14 aumentou significativamente em comparação a T0 (p=0,014), independentemente da presença das contenções. A quebra ou descolagem da contenção relatada pelo paciente foi a única variável que apresentou um impacto negativo na QVRSB (p=0,05). Conclusão: O uso de contenção fixa superior sugere um impacto inicial negativo na qualidade de vida do paciente após o fim do tratamento ortodôntico. Esse impacto, entretanto, é insignificante em longo prazo, exceto quando associado à descolagem ou quebra das contenções ortodônticas. Esse estudo enfatiza a necessidade de acompanhamento contínuo das contenções fixas após a finalização do tratamento ortodôntico.

RESUMO

BACKGROUND: Ectopic eruption of the maxillary first permanent molar is a local disturbance that affects the development of the occlusion. AIM: To evaluate the occurrence of self-correction of maxillary first permanent molar's ectopic eruption and its predictive factors. DESIGN: Five electronic databases and part of the gray literature were investigated. The risk of bias was assessed using the Newcastle-Ottawa scale and the certainty of evidence using the GRADE tool. RESULTS: Four studies were selected: Three had a low risk of bias, and one, moderate. Evidence with a moderate level of certainty was generated, indicating a possibility of 47%-78% of spontaneous correction up to 7 years of age. Supporting the prognosis, whether reversible or irreversible, there was a positive correlation between the severity of the atypical distal resorption of the second primary molar, a higher magnitude of impaction, a larger eruption angle, and a bilateral occurrence with the irreversibility of the cases. CONCLUSION: Spontaneous correction of the ectopic eruption of the maxillary first permanent molar is feasible and dependent on the severity of predictive factors. Early intervention is mandatory in irreversible cases.

RESUMO

BACKGROUND: The concept that posterior crossbite is not self-correcting has been controversial in the literature. OBJECTIVE: To evaluate the incidence of self-correction of crossbite in different stages of dentition in childhood. SEARCH METHODS AND SELECTION CRITERIA: A bibliographic search using the acronym PECOS was performed in five databases and in partial grey literature. Studies evaluating children with posterior crossbite in the deciduous or mixed dentition at initial examination and followed for at least 3 years were included. DATA COLLECTION AND ANALYSIS: The data extraction of the studies included presents information on authorship, clinical characteristics, main results, and conclusions. The risk of bias in the studies was evaluated through the Joanna Briggs Institute tool. The certainty of the evidence was assessed using the GRADE tool. RESULTS: Among the 3045 references identified, seven cohort studies met the eligibility criteria. The studies evaluated patients in transition from deciduous to mixed, mixed to permanent, and deciduous to mixed dentition. Two studies had a low risk of bias, three had a moderate risk, and two had a high risk of bias. The results showed posterior crossbite self-correction frequencies ranging from 12.2 to 77.1% during the transition from primary to mixed dentition, approximately 16% from mixed to permanent dentition, and a range from 20 to 82.8% from deciduous to permanent dentition. The level of certainty of the evidence generated ranged from very low to moderate. LIMITATIONS: The observational design of the studies, without adequate control for confounding factors, and non-classification of the samples considering the types or the severity of the posterior crossbite. CONCLUSION: The self-correction of posterior crossbite in childhood is possible. However, the results of this research do not allow to affirm how often the self-correction of posterior crossbite can occur. New studies that assess factors associated with the occurrence of self-correction of this malocclusion, including oral habits, may increase the certainty of the evidence.

RESUMO

INTRODUCTION: Dental crowding is the most prevalent malocclusion in the mixed and permanent detitions and can have a major impact on dentofacial esthetics. However, adjustments to the development and growth of the dentition can potentiate self-correction of dental crowding during childhood. OBJECTIVE: To evaluate the physiological behavior of mandibular incisor crowding in the transition from mixed to permanent dentition. METHODOLOGY: Five electronic databases (PubMed, Scopus, Web of Science, LILACS and LIVIVO) and part of the gray literature (Proquest and Google Scholar) were investigated, based on the eligibility criteria associated with the acronym PECO, until June 2022. The risk of bias was assessed using the ROBINS-E tool and the certainty of evidence, the GRADE tool. RESULTS: Among the 2.663 studies identified, five were selected for qualitative analysis, of which one have a low risk of bias, and four, a moderate risk. A total of 243 patients were evaluated. Evidence with a high level of certainty was generated indicating a tendency for improvement in mandibular incisor crowding from mixed to permanent dentition, with mandibular incisor crowding decreasing from 0.17 to 4.62 mm on average. The mandibular incisor crowding reduction seems to be associated with the amount of initial crowding and spontaneous dental arch dimensional changes that occur in the mixed dentition and culminate in the increase in arch perimeter, leeway space, incisor protrusion and transverse growth of the maxillary and mandibular arch. CONCLUSION: Based on moderate scientific evidence, spontaneous longitudinal changes in dental arch in the transition from the mixed to the permanent dentition demonstrate a spontaneous improvement in mandibular incisor crowding by up to 4.62 mm. These evidence provide a scientific basis for planning only longitudinal follow-up in patients with mild to borderline moderate mandibular incisor crowding in the mixed dentition avoiding overtreatment.

RESUMO

OBJECTIVE: The aim of this systematic review was to elucidate the role of orthodontic retainers on the stability of compensatory orthodontic treatment in patients with unilateral cleft lip and palate. METHODS: Five electronic databases (PubMed, Scopus, Web of Science, LILACS, and LIVIVO) and the grey literature (OpenGrey and Google Scholar) were investigated, according to the population, exposure, comparator, outcomes and Study design eligibility criterion. The risk of bias assessment was determined based on the Risk of Bias In Nonrandomized Studies of Exposure (ROBINS-E) and the level of evidence with the GRADE tool. RESULTS: Three studies were included: two presented moderate risk of bias and one high. A moderate level of evidence revealed a mean value of 0.6 mm of intercanine relapse distance, and great variability between the data, regardless of the use or type of retention or rehabilitation. Relapse in the posterior region showed clinical significance, from -1 to -1.7 mm, especially in individuals who did not use retention, except in patients with symmetrical arches with Hawley retainer, where this value varies from -0.2 ± 0.63 mm. CONCLUSIONS: Orthodontic retainers do not seem essential to prevent relapse at anterior maxillary dimensions after compensatory orthodontic treatment in patients with unilateral cleft lip and palate. Relapse in the posterior region can achieve greater clinical significance, which highlights the need for prolonged use of Hawley retainers and periodic evaluation of the stability of treatment results. Prospective studies with a longer follow-up can improve the certainty of the evidence.

RESUMO

BACKGROUND: In orthodontics, the retention phase can be considered challenging and unpredictable. Therefore, evidence obtained from different retention protocols is important to facilitate clinical decision-making. OBJECTIVES: This systematic review aimed to compare the clinical effectiveness of bonded versus vacuum-formed retainers (VFRs) regarding their capacity to maintain treatment stability, periodontal effects, and failure rates. SEARCH METHODS AND ELIGIBILITY CRITERIA: Ten databases comprising published and unpublished literature were systematically searched up to August 2021. Randomized clinical trials (RCTs) comparing both retainers were included. DATA COLLECTION AND ANALYSIS: The risk of bias (RoB) evaluation was performed with the Cochrane Collaboration RoB Tool 2.0. All steps of the screening phase and RoB assessment were performed independently by two reviewers. The Grade of Recommendations, Assessment, Development, and Evaluation (GRADE) was used to evaluate the certainty of the evidence. RESULTS: Initial database search yielded 923 studies. After duplicates removal and full-text assessment, five RCTs remained. Overall, the studies presented Low RoB, except one study judged with 'Some concerns'. Based on the included studies, on a short-term (3-6 months) and long-term (4 years) basis, bonded retainers (BRs) were more effective to maintain treatment stability than VFRs in the lower arch. However, from 12 to 24 months both retainers presented the same efficacy. In the upper arch, the retainers were equally effective. BRs were associated with greater plaque and calculus accumulation than VFRs after 12 months. The retainers' failure rates were similar in the upper arch on the first year of retention; however, after 2 years VFRs showed significantly greater failure rates. Contrarily, BRs presented greater failure rates in the lower arch than VFRs. LIMITATIONS: The findings of the included studies may be influenced by different factors related to the unpredictability of relapse. CONCLUSIONS: Most of the evidence generated in this systematic review derived from a moderate level of certainty. In the lower arch, BRs are more effective than VFRs to maintain treatment stability in the initial 6 months of retention and in the long term. In the upper arch, both retention protocols are equally effective. REGISTRATION: Regist0ration number: PROSPERO CRD42020199392.

RESUMO

BACKGROUND: This review synthesizes the available evidence about the predisposition of individuals with asthma or allergies to orthodontically induced inflammatory root resorption (OIIRR) and possible factors related to root resorption that were investigated in the included studies, such as the type of malocclusion, duration of orthodontic treatment, and tooth units. MATERIAL AND METHODS: Six electronic databases and partial gray literature were searched without date or language restrictions until September 2020. Prospective and retrospective observational cohort and case-control studies were included. The risk of bias (RoB) was assessed using the checklists from the Joanna Briggs Institute and the certainty of the evidence using the GRADE tool. To complement the case-control studies, the odds ratio (OR) of the individuals with allergies/asthma to develop root resorption was calculated. RESULTS: Six studies were included. One study with low RoB, one with moderate, and one with high RoB stated that allergic patients did not report a greater chance of developing OIIRR (OR = 1.17 to 2.10, p = 0.1 to 1), while only one study with low RoB reported that individuals with allergies tend to develop root resorption (OR = 2.4, 95% CI = 1.08-5.37). Three studies with low RoB and one with moderate showed no significant association between asthma and OIIRR (OR = 1.05 to 3.42, p = 0.12 to 0.94). No association was identified between the type of malocclusion and the degree of OIIRR. Uniradicular dental units and a prolonged treatment time seem to be associated with an increased risk of resorption. The certainty of the evidence was considered low for both exposure factors. CONCLUSION: Evidence with a low level of certainty indicates that individuals with allergies or asthma are not more predisposed to OIIRR. Uniradicular teeth and long-term orthodontic treatments are associated with a higher risk of OIIRR. SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD42020188463.

RESUMO

BACKGROUND: The aim of this systematic review was to evaluate the effect of micro-osteoperforations (MOPs) performed with Propel and other mini-screws on the rate of tooth movement, pain/discomfort, periodontal health, anchorage loss, and root resorption in patients undergoing orthodontic retraction compared to a control group. MATERIALS AND METHODS: PubMed, Cochrane, Web of Science, LILACS, Google Scholar, Scopus, and OpenGrey were searched without restriction. A manual search was also carried out. Only randomized clinical trials (RCT) were included. The risk of bias (RoB) was assessed using RoB 2.0 and the certainty of evidence through the GRADE tool. RESULTS: Among the twelve RCTs reviewed, five used the Propel system. Overall, the RoB was classified as low (4), moderate (5), and high (3). Two RCTs with moderate and one with a low RoB using the Propel system reported mild increases on rate of tooth movement associated with MOPs. One RCT with a moderate and another with high RoB did not find a significant effect of Propel on orthodontic movement. Regarding tooth movement, a subgroup meta-analysis found no differences between control and Propel movement (95% CI = - 0.01 to 0.75) or other mini-screws (- 0.02 to 0.31) related to rate of tooth movement per month. There was no effect of MOPs on root resorption, periodontal health, anchorage loss, and a mild effect on pain and oral health related to quality of life regardless of mini-screw type. The level of certainty was graded as low for the rate of tooth movement and pain/discomfort, as moderate for anchorage loss, and high for root resorption. CONCLUSION: A low certainty of evidence supports that MOPs performed with Propel seem to have no significant effect on the rate of tooth movement. Moreover, this intervention does not seem to cause an increase in root resorption, periodontal heath, pain/discomfort, or anchorage loss. Thus, the Propel system does not appear to produce different results from those observed for other mini-screws.

RESUMO

Introdução: A escovação com dentifrício fluoretado é o melhor meio para prevenir a cárie dentária, independente da idade. Objetivo: Avaliar o perfil de prescrição de dentifrício fluoretado por cirurgiões dentistas em crianças menores de 06 anos. Métodos: Foram entrevistados 62 odontólogos da rede pública do município de Cascavel ­ PR, e entregue um questionário com seis questões específicas. Resultados: Os cirurgiões dentistas relataram prescrever dentifrício fluoretado (64,5%), e orientam a quantidade a ser colocada na escova (93,5%), também conhecem sobre toxicidade do flúor e as causas da fluorose. Quanto a idade indicada para início da escovação com dentifrício fluoretado as prescrições foram a partir dos 6 anos de idade (24,2%) ou quando a criança soubesse cuspir (17,7%). Conclusão: Os entrevistados prescrevem dentifrício fluoretado para crianças menores de 6 anos de idade. Porém grande parte diferiu sobre a concentração ideal de flúor que deve ser utilizada, além da idade inicial que deve ser prescrito o creme dental fluoretado.

RESUMO

OBJETIVO: verificar o percentual de pacientes que necessitaram extração de dentes permanentes, pré-molares, dentre aqueles tratados com extração de dentes decíduos para correção do apinhamento primário na dentição mista, bem como analisar as possíveis variáveis relacionadas. MÉTODOS: a amostra foi composta por documentações ortodônticas de 70 pacientes na dentição permanente, cujo tratamento iniciou-se na dentição mista com planejamento de um programa de extrações seriadas (PES). Todos os prontuários foram analisados por um único examinador, no intuito de verificar se o PES havia sido cumprido com a extração de dentes permanentes ou se havia sido realizada apenas extração de dentes decíduos. Verificou-se a associação entre a extração de dentes permanentes e as variáveis padrão facial; relação sagital entre as arcadas dentárias; IMPA; proporção tamanho do segundo molar permanente inferior/espaço retromolar; mecânica de controle de espaço e discrepância de modelo (teste exato de Fisher para as variáveis categóricas e modelo de regressão logística para as variáveis numéricas). Os resultados foram considerados para p<0,05. RESULTADOS: dos pacientes que haviam sido tratados com extração de dentes decíduos para a correção do apinhamento na dentição mista, 70 por cento necessitaram de extração de dentes permanentes. A análise estatística não mostrou associação significativa entre as variáveis estudadas e a necessidade de extração de dentes permanentes, com exceção da variável discrepância de modelo. CONCLUSÃO: a discrepância de modelo representou a principal determinante de extração de pré-molares no PES.

OBJECTIVE: To determine the frequency of patients who require extraction of permanent premolars among those treated with extraction of deciduous teeth for the correction of incisor crowding in the mixed dentition and analyze possible associated variables.METHODS: The sample was composed of orthodontic records of 70 patients with permanent dentition whose treatment had begun in the mixed dentition phase and involved serial extraction. All records were analyzed by a single examiner to determine whether serial extraction had been performed with extraction of permanent teeth or only deciduous teeth. Associations were investigated between extraction of permanent teeth and lateral facial pattern, sagittal relationship of the dental arches, incisor-mandibular plane angle, size proportion of mandibular second molar/retromolar space, mechanics for space control and tooth-arch size discrepancy (Fisher's exact test for categorical variables and logistic regression for numeric variables, p<0.05).RESULTS: Among the patients who had been treated with extraction of deciduous teeth, 70% required the extraction of permanent teeth. The statistical analysis revealed no significant associations between the analyzed variables and the need for permanent tooth extraction, with the exception of tooth-arch size discrepancy.CONCLUSION: Tooth-arch size discrepancy was the main factor determining premolar extraction in a serial extraction program.

RESUMO

Objetivo: Verificar a construção teórica das expressões "participação social" e "controle social" relacionando com o processo de construção da democracia na saúde brasileira. Métodos: Pesquisa bibliográfica nas bases Scielo e Lilacs, no período de 2002 a 2009, sendo utilizados os seguintes descritores: Sistema Único de Saúde (SUS), Participação e Controle Social, Política de Saúde. Resultados: O Pós-Constituição de 1988 trouxe a democratização e a descentralização das políticas sociais, abrindo espaço para incontáveis experiências de participação popular. O Sistema Único de Saúde nascia para atender às demandas da população diante daquele momento histórico. Porém, hoje, há mais de vinte anos de sua criação, a falta de compreensão dos princípios que o norteiam, por parte dos profissionais de saúde e população, tem se constituído em um desafio à sua efetivação. Conclusões: Apesar da institucionalização da participação, a cultura de não participação e o desconhecimento de seus instrumentos são entraves importantes à prática de participação social na saúde, a qual representa um trabalho complexo que precisa ser desenvolvido com ativa relação Cidadão-Estado.

Objective: To verify the theoretical construction of the terms "social participation" and "social control" relating them to the process of construction of democracy in Brazilian health. Methods: A bibliographic survey conducted in Lilacs and Scielo databases in the period of 2002 to 2009, using the following descriptors: Unified Health System (SUS), Participation and Social Control, Health Policy. Results: The post-1988 Constitution period brought the democratization and decentralization of social policy making room for countless experiences of popular participation. The SUS was created to meet the demands of the population in face of that historic moment. But today, more than twenty years of its creation, the lack of understanding of its guiding principles by health professionals and the population consists in a challenge to its effectiveness. Conclusions: Despite the institutionalization of participation, a culture of non-participation and the lack of knowledge of its instruments are significant barriers to the practice of social participation in health, which represents a complex work that needs to be developed with active Citizen-State relationship.
