1Department of Social and Preventive Paediatrics, K.E.M.C., Lahore, Pakistan.
Insights
Pakistani infants
Area of Science:
- Pediatric Dentistry
- Human Growth and Development
Background:
- Socioeconomic status significantly impacts child development.
- Understanding primary tooth emergence patterns is crucial for assessing infant health.
Purpose of the Study:
- To investigate the timing of primary tooth emergence in Pakistani infants.
- To explore the influence of socioeconomic status on tooth eruption.
- To compare eruption patterns with international standards.
Main Methods:
- Longitudinal study of 443 Pakistani infants across diverse socioeconomic areas.
- Calculation of mean ages for primary tooth emergence.
- Statistical analysis to identify significant differences and correlations.
Main Results:
- No significant sexual dimorphism observed in tooth emergence timing.
- Infants from lower socioeconomic areas showed significantly earlier emergence of primary teeth 17-20 compared to upper-middle-class infants.
- Pakistani infants demonstrated delayed emergence for primary teeth 1-16 compared to Swedish standards, but were comparable for teeth 17-20.
Conclusions:
- Socioeconomic factors play a role in primary tooth eruption timing in Pakistani infants.
- Pakistani infants exhibit distinct eruption patterns compared to Swedish norms, particularly in early tooth development.
- Further research is needed to understand the underlying causes of these differences.
Abstract:
A sample of 443 Pakistani infants from four different socioeconomic areas was followed longitudinally study the emergence of the primary teeth. The mean ages of emergence of the primary teeth, without regard what kind of tooth and dental ages of the primary teeth were calculated. The subjects showed no sexual dimorphism in the emergence times of the primary teeth. The children from poor areas. were ahead by statistically significant differences from upper middle class, for emergence of the primary teeth 17-20. On comparison with Swedish standards (Hägg & Taranger, 1985) Pakistani children are delayed, by a statistically significant difference, in the emergence of primary teeth 1-16, however, they were at par in the emergence of 17-20 primary teeth.
