Summary
Third molar development, including agenesis (missing teeth), was analyzed in 1700 individuals aged 5-21. Agenesis was more common in males, and a correlation between third molar development and dental age was observed.
Area of Science:
- Dentistry
- Human Biology
- Radiology
Background:
- Third molar development is a key indicator of dental maturation.
- Understanding variations in development and agenesis is crucial for orthodontic and surgical planning.
Purpose of the Study:
- To analyze the characteristics of third molar development in a Czech population.
- To determine the incidence of third molar agenesis and its correlation with age, sex, and dental development.
Main Methods:
- Analysis of 1700 panoramic radiographs from individuals aged 5-21.
- Assessment of seven developmental stages of third molars.
- Statistical comparison of developmental patterns between sexes and agenesis groups.
Main Results:
- Third molar agenesis occurred in 24.2% of males and 17.6% of females.
- A significant correlation was found between third molar developmental stage and overall dental age.
- No other statistically significant sex-based differences in development were observed, except for agenesis.
Conclusions:
- Third molar agenesis is more prevalent in males within the Czech population.
- Dental age is a reliable correlate for third molar development.
- The study provides normative data for third molar development and agenesis in this demographic.
