West Afr J Med. 2022 May; 39(5): 459-464

Abstract

Aim: The study assessed the Plaque and Gingival scores of rural Nigerian school children before and after supervised school brushing program.

Methods: This was an interventional study of 96 children aged 6 to 12 years in selected rural primary schools in Enugu, Nigeria. Data on sex, age, type of school, Plaque score and Gingival score were collected. Data was analyzed using SPSS version 20 and student's t- test was used to compare means. P<0.05 was considered significant.

Results: There were 45(46.9%) male and 51(53.1%) female participants and their mean age was 8.45±1.83years. Forty nine(51.0%) children attended private school while 47(49.0%) attended public school. Only 10(10.4%) had good Plaque score while 8(8.3%) had healthy gingiva. Before intervention, 83(86.5%) children used tooth brush as cleansing tool, 7(7.3%) children brushed twice a day while after the intervention, 96(100.0%) children used toothbrush and 39(40.6%) children brushed twice a day. Also, before intervention, there was significant association between Plaque scores (p=0.012), Gingival scores (p<0.001) and type of school attended. The mean plaque score for the school children before and after intervention was 2.17±0.57, and 1.28±0.49 respectively and the change was statistically significant (p=0.01). The mean gingival score before and after intervention was 1.23±0.67 and 0.31±0.49 respectively and the change was also statistically significant (p<0.001).

Conclusion: Children who attended private schools had better Plaque and Gingival scores than those who attended public schools. Supervised school tooth brushing program improved the plaque and gingival scores of rural primary school children in the study population.
