Summary
A study comparing two generations of children found a significant decrease in caries affecting occlusion. While anteroposterior relationships remained stable, normal occlusion declined, with a rise in Class I malocclusion prevalence.
Area of Science:
- Dentistry
- Orthodontics
- Public Health
Background:
- Occlusal patterns in children can change over time due to various factors.
- Understanding secular trends in occlusion is crucial for dental public health planning.
Purpose of the Study:
- To investigate secular trends in occlusal patterns between two generations of children.
- To compare the prevalence of different occlusal relationships and malocclusions.
Main Methods:
- Comparative analysis of occlusal patterns in two generations of children (Group A and Group B).
- Exclusion of children with caries affecting occlusion or in the deciduous dentition stage.
- Analysis of molar and canine anteroposterior relationships and occlusion types.
Main Results:
- A significant decrease in the prevalence of caries affecting occlusion was observed.
- No significant differences were found in molar and canine anteroposterior relationships between the groups.
- A decrease in normal occlusion was noted, alongside an increase in Class I malocclusion.
Conclusions:
- Occlusal patterns in children have evolved over generations.
- Class I malocclusion is becoming more prevalent, while caries affecting occlusion has decreased.
- Further research into the etiology of these changing occlusal trends is warranted.
