| Resumo: | Malocclusion results from changes in the dental position and poor relationship of the
maxillary bones, being considered a phenomenon of modern civilizations that can be
classified as a Public Health problem. The aim of this study was to validate an instrument for
the diagnosis of malocclusion in the deciduous dentition by dental surgeons. This is a
methodological study, with a quantitative approach, developed in two stages. The first
consisted of content and appearance validation by a panel of judges composed of five
orthodontic dentists; and the semantic analysis of the items, using the brainstorming
technique, which consisted in checking the comprehension of the items by two groups of
three non-orthodontic dentists. In the second stage, the psychometric properties were
assessed, which evaluated the instrument by three dental surgeons, on two different occasions,
the same group of 112 children, aged three to five years, verifying the reliability of the
instrument. Data analysis was performed using the Content Validity Index (IVC), Kappa (k)
concordance coefficient and Spearman’s correlation coefficient. The research followed all the
ethical and legal aspects of human research, obtaining the opinion of the Commission of
Ethics in Research under No. 2.803.127. In relation to clarity, Domain 01, regarding the
identification of the child, obtained IVC = 1. Domain 02, regarding the evaluation criteria,
was initially composed of 11 items, four were evaluated with IVC = 1, four with CVI = 0.8,
however, items VII and VIII were considered unclear or unclear, with IVC 0.6 and 0.2.
Domain 03, referring to the general result, the two items that compose it received IVC = 1. In
the evaluation of the instrument as a whole, two items received IVC = 1 and an IVC = 0.8.
Regarding the relevance of the items in Domain 02, seven obtained IVC = 1 and two IVC =
0.8, however, items VII and VIII were considered as less relevant or irrelevant, with IVC 0.66
and 0.50. The representativity of Domain 03 presented IVC = 0.8. In the evaluation of the
three domains of coverage, it was verified that two obtained IVC = 1.00 and one obtained
IVC = 0.8; and the instrument as a whole had IVC = 0.8. According to the judges'
suggestions, the instrument was modified, obtaining the primary version. As for the semantic
analysis, it was observed that of the ten items that make up the primary version of Domain 02,
eight were considered comprehensible, however, items VIII and X were considered nonunderstandable, with IVC 0.66 and 0, 50. The three domains of the instrument obtained IVC =
1.00 in relation to the understanding of the items and words; filling in the answers. According
to the suggestions, the secondary version of the instrument was obtained. The domains and
items of the secondary version, obtained IVC = 1.00 in all aspects analyzed. When evaluating
the psychometric properties, it was observed that there was an almost perfect inter-rater
agreement (k≥0.8), and that the instrument was consistent in time and space by the three
observers, obtaining a strong Spearman coefficient (rs> 0, 80). At the application of the
instrument, it was verified that the majority of children (97.3%) were diagnosed with
orthodontist evaluation (score ≥15). Thus, the alternative hypothesis of the study is accepted,
in which it is evident that the instrument for the diagnosis of malocclusion in the deciduous
dentition by dental surgeons has strong evidence of validity. Thus, it is expected that the
product obtained from this study will allow the dental surgeon to guide and refer children to
specialized services during the deciduous teething phase, guaranteeing comprehensive care
for this population. |
