Hypothesis
This study aims to determine the prevalence of hypodontia of permanent teeth in Korean orthodontic patients and its association with dental clinic type, patient gender, and malocclusion type.
Conclusion
The study found a relatively high prevalence of hypodontia at 11.3%, highlighting the need for early dental examinations and radiographic screenings.
Supporting Evidence
- The overall prevalence of hypodontia was found to be 11.3%.
- The most commonly missing teeth were the mandibular second premolars (44.2%).
- 86.0% of patients with hypodontia were missing one or two teeth.
- The prevalence of hypodontia was not significantly different between genders.
- The study included patients aged 9 to 30 years.
Takeaway
Many kids in Korea are missing some teeth, and it's important for them to see a dentist early to check for this.
Methodology
The study evaluated 3,055 patients using panoramic radiographs, clinical examinations, and dental casts over five years.
Potential Biases
The sample may be biased as it includes patients referred for orthodontic treatment, potentially skewing prevalence rates.
Limitations
The study's sample consisted of orthodontically selected individuals, which may not represent the general population.
Participant Demographics
The participants had a mean age of 15.1 years, with 39.4% male and 60.6% female.
