Knowledge and awareness of orthodontics among Nigerian school children in selected private and public schools in Lagos

Abstract

Objective: This study sought to assess the knowledge and awareness of Nigerian adolescents concerning orthodontics, to determine possible factors influencing their knowledge of orthodontics as well as to find out if socioeconomic status has any effect on their knowledge and awareness.
 Method: This cross-sectional descriptive questionnaire based study was conducted in two secondary schools (one private and one public) in Lagos State.
 Result: A total of 408 students, participated in the study of which only 98 (24.0%) had ever heard the term ‘orthodontics’, and of this number only 16 could correctly explain the meaning of the term orthodontics. Majority of the respondents with correct responses attended a private school. Significantly more of the private school students correctly identified that orthodontists are involved in rearranging the teeth (p=0.006) and not involved in cleaning the teeth (p=0.008). There was a significant difference in the knowledge of the students from the public and private school concerning the impact of malocclusion on speech (p=0.002) and appearance (p=0.000). The overall orthodontic knowledge is deficient. However knowledge was better among the children from the private school compared to those from the public school. The results obtained from this study, clearly show that there is need to provide oral health education especially to improve the orthodontic knowledge of these adolescents especially about malocclusion and its consequences. It is expected that this would improve their knowledge and consequently increase the demand for and the uptake of the available orthodontic services.
