ABSTRACT
BACKGROUND: Malocclusion is an abnormality of teeth alignment from interactions of hereditary and environmental factors, associated with stimuli present at the period of formation and development of the face and oral tissues.
OBJECTIVES: To determine the prevalence and determinants of malocclusion among preschool children in Maiduguri, Borno State.
METHODS: This study involved 239 pre-school children selected by systematic random sampling. The independent variables were ‘presence / absence of sucking habits’, ‘type of sucking habit’, ‘molar relationship’ and ‘nutritional status. The dependent variable was presence of malocclusion and ‘type of malocclusion. Frequency distribution of independent and dependent variables were presented. Association between the independent and dependent variables were obtained using Chi-Square test. Statistical significance was placed at 95% confidence intervals, p value ≤ 0.05. Data was analysed using SPSS for Windows (version 23).
RESULTS: Majority of participants were in the higher social class, (P=0.07), never had a dental visit (78.2%), P=0.08 and did not have any sucking habit (82.4%), P= 0.03. Most had mesial step (42.7%) or flush terminal molar relationship (37.7%), P=0.05. Prevalence of malocclusion was 4.5%, majority were cross bite (64.4%) SE=0.04. Distal step and flush terminal molar relationship were associated with prevalence of malocclusion (12.5% and 4.4% respectively), P=0.08.Fifty percent of those with digit sucking habit had cross bite, P=0.01.
CONCLUSIONS: Prevalence of malocclusion among preschool children in this study was low and majority had cross-bite. Digit sucking was significantly associated with cross bite. Children with distal step occlusion exhibited higher proportion of malocclusion. There is need for dental awareness on malocclusion among the population.
