Age and wisdom teeth in Nigeria.
Summary
This study estimates wisdom teeth eruption in North Nigerians, finding they generally erupt between 15-21 years. Eruption timing varies slightly by sex and jaw/side, with 5% experiencing impaction.
Area of Science:
- Anthropology
- Dentistry
- Human Biology
Background:
- Wisdom teeth (third molars) eruption patterns are crucial for understanding human dental development.
- Variations in eruption timing can indicate population-specific genetic or environmental factors.
- Limited data exists on third molar eruption in the North Nigerian population.
Purpose of the Study:
- To estimate the eruption age of wisdom teeth in a North Nigerian population.
- To identify any sex-based differences in third molar eruption timing.
- To establish a normative range for wisdom teeth eruption in this demographic.
Main Methods:
- Cross-sectional study involving 654 boys and 584 girls aged 11-23 years.
- Data collection focused on observing and recording the eruption status of third molars.
- Statistical analysis to determine mean eruption ages and ranges.
Main Results:
- Wisdom teeth generally erupt between 15 and 21 years in North Nigerians.
- Lower jaw teeth erupt before upper jaw teeth; left-side teeth erupt before right-side teeth.
- Boys show slightly earlier eruption (18 years) than girls (18.5 years); 5% of individuals had unerupted wisdom teeth.
Conclusions:
- The study provides normative data for third molar eruption in North Nigerians.
- Eruption patterns exhibit predictable sequences (jaw, side) and minor sex-related differences.
- Understanding these eruption dynamics is vital for clinical dental assessments and anthropological studies.
