Objectives: To determine the effects of the introduction of oral health education and educational materials on the oral health status of Nigerian students.

Methods: As part of a single blind, randomized controlled trial to assess an oral health education intervention, 964 12-year-old school children from 32 public schools were recruited. They were proportionately selected through a multistage sampling technique. The schools were randomized into either an education intervention (case) or a normal care group (control). Baseline oral health parameters (DMFT & CPITN) were documented prior interventions. The intervention included lectures, demonstrations, educational materials and follow-up revisions (by local teachers) on oral health care. Follow up examination took place 6 months later. All the examinations were conducted by one examiner (intra-examiner reliability test was 0.852 by Cronbach’s Alpha test). Analysis was by the use of SPSS V15.0. Pearson’s Chi-squared test and t-test were used to test for association between variables. P-values <0.05 was considered statistically significant. Results: There were 590 (61.2%) boys. 55.1% (531) students were from the urban areas. At follow up visit, 655 (67.9%) students were available. 284 (43.4%) were girls, a total of 279 (42.6%) were from the rural areas. Mean DMFT (case) before and after intervention was 0.178 ± 0.62 and 0.138 ± 0.46 respectively (p>0.05); control was 0.143 ± 0.54 and 0.166 ± 0.57 (p>0.05). CPITN score (No 2) for case, before and after intervention was 83.1% and 85.3% respectively. Control was 87.4% and 91.5% (p>0.05). There was no significant change post intervention for mean DMFT and CPITN by gender and location.
Conclusions: There was no significant change in the oral health status of 12 year old Nigerian students six months after an oral health educational intervention was introduced.
