Prevalence of Angle's malocclusion according to age groups and gender

ABSTRACT

To assess the prevalence of Angle's Malocclusion in relation to different age groups and gender in general population. A cross sectional study was done at Dow Dental College during period of 2012- 2013. Six hundred participants were selected according to inclusion criteria by using a non-randomized purposive sampling technique. Visual observation was done to find whether the participants had class 1, 2 and 3 in relation to self-designed age groups and gender. Data was collected by questionnaire filled by the researcher and was further analysed by using computer software SPSS 16.0. Pearson chi square was applied to observe whether the prevalence of Angles Malocclusion is dependent on different age groups and gender. Class 1 demonstrated to be the most established malocclusion. Females were observed to have more class 1 than males. Conversely Pearson chi square did not reveal any statistical significant result of Angles Malocclusion in relation to different age groups and gender. In this cross-sectional study, the prevalence of malocclusion traits did not change as shown by the p-value being insignificant. Cross-sectional studies of younger population groups are to be used for research into the long-term physiological effects of malocclusion to know if certain and specific malocclusion traits are stable over time
