Interrelationship between dental age and chronological age in Somali children
1Department of Child Dental Health, School of Clinical Dentistry, University of Sheffield, UK.
Insights
Somali children show advanced dental development compared to Caucasian children. This indicates a need for ethnicity-specific standards in dental age assessment for better accuracy.
Area of Science:
- Pediatric Dentistry
- Anthropology
- Human Growth and Development
Background:
- Accurate dental age assessment is crucial for monitoring child development and health.
- Existing dental age standards may not be universally applicable across diverse ethnic groups.
Purpose of the Study:
- To compare dental age (DA) with chronological age (CA) in Somali and white Caucasian children.
- To investigate potential ethnic differences in dental maturation.
Main Methods:
- A cross-sectional study was conducted involving Somali and Caucasian children under 16.
- Dental age was determined from panoramic radiographs and compared to chronological age.
- Independent sample t tests were used to analyze differences between ethnic groups and genders.
Main Results:
- Somali children exhibited a significantly greater difference between dental age and chronological age compared to Caucasian children.
- The mean difference (DA-CA) was higher in Somali boys (1.01 years) and girls (1.22 years) than in Caucasian boys (0.19 years) and girls (0.52 years).
- Marked discrepancies between dental and chronological age were observed in some Somali children, particularly between 8 and 12 years of age.
Conclusions:
- Somali children demonstrate significantly advanced dental development relative to their Caucasian peers.
- The findings underscore the necessity of developing population-specific dental development standards.
- Accurate dental age assessment requires consideration of ethnic background.
Objective:
To compare dental age (DA) with chronological age (CA) in Somali and white Caucasian children, resident in Sheffield.
Design:
Cross-sectional study.
Setting:
Paediatric dentistry clinic, Charles Clifford Dental Hospital, Sheffield.
Subjects:
Somali children under 16 years of age and age- and gender-matched white Caucasian subjects.
Outcome Measures:
Dental age was determined for each subject, using their existing panoramic radiographs. Comparisons of the difference between dental age and chronological age (DA-CA) were made for gender and ethnic group, using independent sample t tests at the 0.05 level of significance.
Results:
The sample group comprised 162 subjects: 84 Somali and Caucasian boys (mean age 10.55 years) and 78 Somali and Caucasian girls (mean age 11.24 years). The mean difference between DA and CA was found to be 1.01 years for Somali boys, 0.19 years for Caucasian boys, 1.22 years for Somali girls, and 0.52 years for Caucasian girls. The difference between DA and CA was significantly greater in Somali subjects than in Caucasian children. A few Somali subjects showed a marked discrepancy between chronological age and dental age (range -1.75 to 5.42 years), which was most evident in 8- to 12-year-old children.
Conclusion:
Somali children are significantly more dentally advanced than their Caucasian peers. This finding highlights the need for population-specific dental development standards for accurate dental age assessment.
