Eruption times of third molars in young rural Nigerians.
The eruption pattern of third molar amongst 1071 rural Nigerians (523 males and 548 females) aged 11-21 years was assessed. The earliest age at which the third molar erupted for males and females was 14 and 13 years respectively with females significantly ahead of males (P < 0.01). A full compliment of erupted third molars was recorded at age 14 years in 1.1 per cent of the population. However, the mean age for the eruption of 1, 2, or 3 and all third molars were 16.58 and 17.50 years respectively. Whilst third molar-eruption was significantly earlier in the mandible, no right-left side differences were found. Problems often associated with the erupting third molars are likely to be seen earlier in young rural Nigerians than in the western countries.
