BACKGROUND: Videos as a medium of health education are useful tools. This study evaluated the effectiveness of a dental health education video in the Yoruba language (spoken in southwestern Nigeria) targeted at children from the lower socioeconomic class. METHODS: An interventional study was conducted among 120 children aged 11 and 12 years, randomly selected from three public primary schools in Ibadan, Nigeria. Participants were assigned into three study groups: group 1 watched the video, group 2 received verbal dental health education in the Yoruba language and group 3 were the control. Following this, each participant received a full mouth prophylaxis, and six weeks later, their oral hygiene was assessed using the Simplified Oral Hygiene Index of Greene and Vermillion. RESULTS: A mean debris score of (1.11), (1.04) and (1.57) was recorded for the video, verbal and control groups respectively (p<0.001). The mean calculus index score was lowest among the verbal group (0.56), followed by the video group (0.75) and highest among the control (1.16) (p<0.001). However, multivariate analysis, controlling for child's age and fathers education, revealed that oral hygiene of the participants in the video group was significantly better by 28.6% compared to the control group while in the verbal education group there was an improvement of 23.4 % in contrast to the control . CONCLUSION: This study demonstrated that a culturally appropriate video in an indigenous language can significantly improve oral hygiene among school children from the lower socioeconomic group in Nigeria.
This study has shown that referral letters written from various peripheral healthcare centers to the dental centre of a teaching hospital is generally of unacceptable quality and the content could be improved upon.
Fluoride intake in these 4- and 8-year-old Nigerians was much higher than the "optimal range" of 0.05-0.07 mg/kg bw/d in rural, higher F water areas, with diet as the main contributor. F retention was similar in both age groups, with almost half of TDFI retained in the body. In terms of risk vs benefit for fluorosis and dental caries, this finding should be considered when mitigating against excessive fluoride exposure and planning F-based prevention.

BSTRACT
Objectives:
This narrative review aimed to show the approaches recommended for the prevention of dental caries in Nigeria by epidemiological surveys (P), primary preventive methods and strategies,( I) comparison preferred by experts (C) in the prevention of dental caries (O).
Methods:
An electronic literature search of some databases such as Pubmed, Pubmed Central, Google Scholar, African Journal Online (AJOL) and Medline was conducted using these keywords delimited by Boolean operators AND, OR and NOT: “dental caries” “prevention” “Nigeria. Epidemiological studies using WHO criteria published in English between 1999 and 2019 were included in this study.
Results:
All studies that met the inclusion criteria were epidemiological cross-sectional studies, non-clinic –based. The approaches recommended include need for continuous caries surveillance, preventive and restorative programmes, primary prevention, use fluorides, oral health education and atraumatic restorative treatment.
Conclusions:
The recommended approaches should include continuous caries monitoring, comprehensive preventive and restorative programmes, primary prevention, use fluorides, oral health education and atraumatic restorative treatments in public schools and primary health care (PHC) centres. It is necessary to augment these approaches with undergraduate cariology curriculum review of dental schools, public-private partnership and oral health policy implementation with emphasis on prevention.
