A new Index for Assessing Surgical Outcome in Unilateral Cleft Lip and Palate Subjects Aged Five: Reproducibility and Validity

Abstract

This study has provided a reliable and reproducible index for assessing the outcome of surgery in UCLP subjects earlier than indices already available. True validation of the index was not possible but it appears that it relies on face validity.

What are the occlusal outcomes for unilateral cleft lip and palate patients? A national project in the UK

“…2 These two meth ods assess early anterior-posterior growth of the jaws of UCLP patients using orthodontic study models. This gives an E18 indication of the effect of the primary surgery required to repair the cleft, on growth of these structures.…”

Does relative maxillary arch constriction worsen with growth in patients with cleft lip and palate? A pilot study

“…[9] The 5 year old index was developed to allow surgical results to be assessed in younger patient. [10] However, both are 5-point categorical indices whilst, the MHB index is an ordinal scale index that can be used at any age. As a result, the MHB index allows more precise occlusal differences to be detected, enabling the determination of more subtle differences between groups.…”

Avaliação do tamanho das lâminas palatinas no resultado do crescimento dos arcos dentários e relação interarcos na dentadura decídua ou mista precoce

“…Foi utilizado o Índice dos 5 anos, proposto por Atack et al (1997), que define critérios de sistematização para quantificar e qualificar a morfologia da oclusão em pacientes com fissura completa de lábio e palato unilateral, compreendendo uma escala de 1 a 5, com grau crescente de severidade e considerando a relação interarcos, a forma do arco dentário superior e a inclinação dos incisivos superiores. O objetivo do método consiste em facilitar o prognóstico e a aplicação de protocolos terapêuticos no tratamento dos pacientes com fissuras de lábio e palato.…”

“…As lâminas palatinas foram medidas de imagens escaneadas dos modelos das fases 1 e 2, utilizando-se do programa Adobe Photoshop CS2. O índice oclusal foi avaliado nos modelos das fases 3 utilizando o índice de proposto por Atack et al 1997, conhecido por índice dos 5 anos de idade. A medida das lâminas palatinas foi comparada entre as fases 1 e 2 e mostrou haver um crescimento médio de 0,5 cm.…”

“…The palatal shelves were measured on scanned images of dental casts of stages 1 and 2, using the software Adobe Photoshop CS2. The occlusal index was evaluated on the dental casts of stage 3 using the index proposed by Atack et al 1997, known as 5-year-old index. The dimension of palatal shelves compared between stages 1 and 2 evidenced a mean growth of 0.5 cm.…”
