Impact of School-Based Oral Hygiene Education on Knowledge and Attitude among School Children Aged 10–15 Years in a Selected Rural Community of Bangalore
Abstract: This quasi-experimental study evaluated a structured teaching program (STP) designed to improve oral hygiene knowledge and attitudes in 10–15-year-old students from a rural Bangalore community. Before the program, most students demonstrated limited understanding of dental care and negative attitudes toward oral hygiene. After the STP, both knowledge and favorable attitudes increased markedly (paired t-test, p<0.001). For example, the mean knowledge scores increased substantially after the intervention, demonstrating a level of …
