Are severe occlusal problems more frequent in permanent than deciduous dentition?

Abstract

ObjectiveTo determine the prevalence and severity of occlusal problems in populations at the ages of deciduous and permanent dentition and to carry out a meta-analysis to estimate the weighted odds ratio for occlusal problems comparing both groups. Methods Data of a probabilistic sample (n=985) of schoolchildren aged 5 and 12 from an epidemiological study in the municipality of São Paulo, Brazil, were analyzed using univariate logistic regression (MLR). Results of cross-sectional study data published in the last 70 years were examined in the meta-analysis. ResultsThe prevalence of occlusal problems increased from 49.0% (95% CI =47.4%-50.6%) in the deciduous dentition to 71.3% (95% CI =70.3%-72.3%) in the permanent dentition (p<0.001). Dentition was the only variable significantly associated to the severity of malocclusion (OR=1.87; 95% CI =1.43-2.45; p<0.001). The variables sex, type of school and ethnic group were not significant. The meta-analysis showed that a weighted OR of 1.95 (1.91; 1.98) when compared the second dentition period with deciduous and mixed dentition. ConclusionsIn planning oral health services, some activities are indicated to reduce the proportion of moderate/severe malocclusion to levels that are socially more acceptable and economically sustainable. (IC 95% =47,6) na dentição decídua para 71,3% (IC 95% =70,3) na dentição permanente (p<0,001). O tipo de dentição foi a única variável estatisticamente associada à presença de má oclusão moderada/severa (OR=1,87; IC 95% =1,45; p<0,001 Resumo Objetivo Analisar a prevalência e severidade de problemas oclusais em populações em idades relacionadas à dentição decídua e permanente, e efetuar uma meta-análise para estimar odds ratio ponderada para problemas oclusais comparando os dois grupos.

Oral Health and Occlusion in Tunisian Preschool Children

“…As Frazao et al [26] previously reported in 2004, our study suggested that severity of malocclusion was significantly associated with dental caries but not with gender or ethnic group. In fact, malocclusion has long been accepted as a risk factor for dental caries because of increased food and plaque accumulation in areas of crowding.…”

Malocclusion and socioeconomic indicators in primary dentition

“…Previous investigations report rates ranging from 36.46% to 87.0% in Brazilian studies [14][15][16][17] overjet. The measurement (in millimeters) was performed with the teeth in centric occlusion and the probe positioned parallel to the occlusal plane.…”

Epidemiology of malocclusion in children and adolescents: a critic review

“…The majority of the publications (57%) were concentrated in the last five years (12) There was diversity as regard the periodical published, however, the following periodicals: Revista Gaúcha de Odontologia, Jornal Brasileiro de Odontopediatria e Odontologia para Bebê, Community Dentistry and Oral Epidemiology, Australian Orthodontic Journal and European Journal of Orthodontics were those that allowed the largest number of articles to be located (2 in each) 6,[8][9][10][11]13,[17][18][19]21 . The other periodicals presented a uniform distribution with one article in each [2][3][4][5]12,[14][15][16]20 .…”

“…With regard to the criteria adopted in the studies, 12 articles adopted the DAI 4-5,13,17,19-20 , 7 articles selected used more than one index for evaluating malocclusion 4,5,8,15,17,19,20 , 6 articles adopted the IOTN index 4,5,13,17,19,20 , 5 articles related the prevalence of diverse occlusal alterations 2-3,6,12,21 and 2 articles used the Angle classification 9,23 .…”

“…With regard to sample selection, it was randomly performed in 5 studies 2,4,6,9,14 , randomized in another 5 11,[17][18][19]22 , by convenience in 7 articles 5,8,10,[12][13][20][21] , probabilistic in 2 [15][16] and 2 by conglomerate 3,23 .…”
