Hypothesis
The study aims to evaluate and compare the size and position of the mandibular condyle among male and female patients with different skeletal patterns using CBCT images.
Conclusion
Class I individuals have smaller posterior joint space compared to Class III individuals, while Class II individuals have shorter condyle lengths than both Class I and Class III.
Supporting Evidence
- Class I individuals had lower PS values compared to Class III individuals.
- Class II individuals had shorter condyle lengths compared to those in Class III and Class I.
- Different skeletal patterns did not show a statistically significant effect on the superior space.
Takeaway
This study looked at how the shape and position of a part of the jawbone, called the condyle, can be different in people with various jaw shapes, helping doctors plan better treatments.
Methodology
The study analyzed CBCT images of 119 patients classified into three skeletal pattern groups based on ANB angles and Wits analysis.
Potential Biases
The study did not account for other potential factors, such as TMD, in the development of skeletal malocclusions.
Limitations
The unequal distribution of male and female participants across skeletal classes may affect the generalizability of the findings.
Participant Demographics
The sample consisted of 33 males and 86 females, aged 16 to 77 years, with an average age of 32.86 years.
Statistical Information
P-Value
p = 0.015 for PS size difference between Class I and Class III.
Statistical Significance
p<0.05
