ABSTRACT
Background
Knowledge of arch dimensions is useful in providing a smooth occurrence of transient malocclusion, in predicting future orthodontic problems, normal occlusal changes in mixed dentition, and proper sequential exchange of permanent teeth. Moreover, dental arch dimensions change systematically during the period of intensive growth, development and less so in adulthood. The findings of the present study exhibited the highly significant greater mean value for males than females in both mixed and permanent dentitions except dental arch length and total arch length measurements in the permanent dentition in which no significant differences were reported.
Objective
This longitudinal study was conducted to investigate dental arch width, length and depth changes that happen at two different stages of dentition in 40 (20 males and 20 females) normal occlusion Kurdish children.
Materials and Methods
Dental casts were obtained and measurements were analyzed twice with 5 years intervals using digital sliding calipers with 0.001 sensitivity. First measurement was in mixed and second one in permanent dentition. The data were analyzed using SPSS (version 15) program.
Results
The results showed that width changes in maxilla and mandible were significantly more in the permanent dentition than mixed dentition. Additionally, the findings demonstrated a greater mean value of measurements for males than females in both mixed and permanent dentitions except dental arch length (DAL) and total arch length (TAL) in the permanent dentition. Thus, significant sexual dimorphism was observed in most dimensions measured.
Conclusion
The outcome of the present study demonstrates that changes in dental arch dimensions should be taken in consideration during orthodontic treatments rendering the upshot of the treatment more acceptable.
