No. of bitstreams: 0 Previous issue date: 2006 / Contexto: Mordida aberta anterior (MAA) ocorre quando incisivos superiores não tocam incisivos inferiores. A etiologia é multifatorial, incluindo: hábitos orais, padrão de crescimento desfavorável, aumento de tecidos linfáticos com respiração bucal. Vários tratamentos têm sido propostos para corrigir esta má-oclusão. As intervenções não são suportadas por forte evidência científica. Objetivos: O objetivo desta revisão sistemática foi avaliar tratamentos ortodônticos e ortopédicos para corrigir MAA em crianças. Estratégia de pesquisa: Estratégias de pesquisa foram desenvolvidas para a MEDLINE e elaboradas para as seguintes bases de dados: Cochrane Oral Health Group Trials Register, PubMed (1966-2005); EMBASE (1980-2005); Lilacs (1982-2005); BBO (Biblioteca Brasileira de Odontologia) (1986-2005); SciELO (1997-2005). Revistas chinesas foram manualmente pesquisadas e as bibliografias dos artigos foram checadas. Critérios de Seleção: Todos os ensaios clínicos controlados randomizados ou quasi-randomizados de tratamentos ortodônticos e/ou ortopédicos para correção de MAA em crianças. Coleta de dados e análise: Dois revisores, independentemente, avaliaram a elegibilidade de todos os artigos identificados. RR, NNT e intervalos de confiança de 95% foram calculados para dados dicotômicos. Os resultados expressos em dados contínuos foram apresentados conforme descritos pelo autor. Principais resultados: Vinte e sete estudos foram eleitos, três ensaios clínicos controlados randomizados foram incluídos, comparando: efeitos do Regulador de função de Frankel-4 (RF4) com treinamento de selamento labial versus não tratamento, bite-blocks com magnetos versus bite-blocks; grade palatina associada à mentoneira versus não tratamento. O estudo com bite-blocks magneto versus bite-blocks não pôde ser analisado porque os autores interromperam o tratamento antes do que o planejado em função de efeitos colaterais em quatro dos dez pacientes. RF4 com treinamento de selamento labial e grade palatina associada à mentoneira foram capazes de corrigir MAA. Nenhum estudo descreveu: processo de randomização, cálculo do tamanho da amostra, mascaramento nas análises de dados. Dois estudos avaliaram duas intervenções ao mesmo tempo. Portanto, os resultados devem ser vistos com cautela. Conclusões dos revisores: Há alguma evidência de que as intervenções RF4 com treinamento de selamento labial e grade palatina associada à mentoneira são capazes de corrigir MAA. Os estudos incluídos têm potenciais vieses, portanto, os resultados devem ser vistos com cautela. Mais ensaios clínicos randomizados são necessários para elucidar as intervenções para tratamento de mordida aberta anterior. / Background: Anterior open bite occurs when upper incisors do not touch lower incisors. The aetiology is multifactorial including: oral habits, unfavorable growth pattern, enlarged lymphatic tissue with mouth breathing. Several treatments have been proposed to correct this malocclusion, but interventions are not supported by strong scientific evidence. Objectives: The aim of this systematic review was to evaluate orthodontic and orthopaedic treatments to correct anterior open bite in children Search strategy: Search strategies were developed for MEDLINE and revised appropriately for the following databases: Cochrane Oral Health Group Trials Register; The Cochrane Central Register of Controlled Trials (CENTRAL): The Cochrane Library , current Issue; PubMed (1966 to 2005); EMBASE (1980 to 2005); Lilacs (1982 to 2005); BBO (Bibliografia Brasileira de Odontologia) (1986 to 2005); SciELO (1997 to 2005). Chinese journals were handsearched and the bibliographies from papers were retrieved. Selection criteria: All randomised or quasi-randomised controlled trials of orthodontic and/or orthopaedic treatments to correct anterior open bite in children. Data collection & analysis: Two authors independently assessed the eligibility of all reports identified. Risk ratios, NNT and corresponding 95% confidence intervals were calculated for dichotomous data. The results presented as continuous data were expressed as described by author. Main results: Twenty seven trials were eligible, and only three randomised controlled trial were included comparing: effects of Frankel's functional regulator-4 (RF4) with lip-seal training versus no treatment; repelling-magnet splints versus bite-block; palatal crib associated with high-pull chincup versus no treatment. The study with repelling-magnet splints versus bite-block could not be analysed because the authors interrupted the treatment earlier than planned due to side effects in four of the ten patients. RF4 associated to lip-seal training and removable palatal crib combined with high-pull chincup were able to correct anterior open bite. None study described: randomisation process, size sample calculation, there was no blinding in the cephalometric analysis and the two studies evaluated two interventions at the same time. So, these results should be viewed with caution. Reviewers' conclusions: There is some evidence that the interventions RF4 with lip-seal training and palatal crib associated with high-pull chincup are able to correct anterior open bite. Given that the trials included have potential bias, these results must be viewed with caution. So, recommendations for clinical practice can not be made based only on the results of these trials. More randomised controlled trials are needed to elucidate the interventions for treating anterior open bite. / BV UNIFESP: Teses e dissertações

abstract: Modern primate diet is well-studied because of its considerable influence on multiple aspects of morphology, including the shape of the facial skeleton and teeth. It is well-established that differences in craniofacial form influence feeding abilities by altering the nature of bite force production. Tooth morphology, likewise, has been shown to vary with diet across primates, particularly in the details of occlusal form. It has also been suggested that tooth form (e.g., tooth root size and shape and crown size) reflects, in part, the demands of resisting the stresses generated during feeding. However, while they are central to our efforts to infer diet in past species, the relationships between bite force production, craniofacial morphology and tooth form are not well-established. The current study is separated into two parts. In Part I, the hypothesis that crown size and root surface area are adapted to resist masticatory stress is evaluated by testing whether these features show correlated variation along the tooth row in a taxonomically diverse sample of primates. To further explore the adaptive nature of this correlation, pair-wise comparisons between primates with mechanically resistant diets and closely-related species consuming less resistant foods are performed. If crown size and root surface area covary along the tooth row, past research suggests they may be related to bite force. To test this hypothesis, Part II examines the variation of these dental characteristics in comparison to theoretically-derived bite force patterns along the tooth row. Results suggest that patterns of maximum bite force magnitude along the tooth row are variable both within and between species, underscoring the importance of individual craniofacial variation on masticatory force production. Furthermore, it is suggested that some adaptations traditionally associated with high bite force production (i.e., facial orthognathy) may increase anterior biting force at the expense of posterior biting force. Taken together, results from the current study reveal that both tooth root and crown size vary in conjunction with the mechanical properties of diet and with bite force patterns along the tooth row in anthropoids. / Dissertation/Thesis / Ph.D. Anthropology 2012
