Oral health in Nigeria.

Most oral health surveys in Nigeria have been sporadic and based on convenience samples. Periodontal disease with deep pocketing occurs in Nigerians at an early age, the prevalence being 15-58% in those aged above 15 years. Caries experience has been reported to vary between very low and low in most studies, but is moderate in some urban communities. Although mean DMFT is below 4 in most communities, the restorative index is extremely low, most carious teeth remaining unrestored. The higher caries prevalence in second than first permanent molars that has been reported is most likely due to a change from traditional to Western-type diet. Other oral health problems include malocclusion, truamatised teeth, dental fluorosis, and oral tumours. The scanty oral health services available in the country are mainly in urban areas. There is, therefore, a need to develop sustainable strategies for national preventive and therapeutic oral health services in Nigeria.
