Research summary
This study focuses on a dental condition called mandibular canine impaction, which happens when the lower eye tooth (the pointed tooth next to the front teeth) doesn't come through the gum properly by the expected age. This can cause problems such as crooked teeth, damage to nearby teeth, and aesthetic concerns. In rare cases, the tooth can even move across to the opposite side of the jaw, a condition known as transmigration.
How often this condition occurs can vary in different populations. Studies have reported that between 0.92% and 5.1% of people have impacted lower canine teeth, while less than 1% have transmigration. However, there's limited information about how common these issues are among people in Scotland. Understanding how often these conditions occur and what they typically look like can help clinicians diagnose and treat them earlier, which can lead to better results for patients.
This study aims to find out how common these conditions are and what features they have in patients referred to the Orthodontic Department at the Edinburgh Dental Institute. By identifying patterns and possible risk factors, the research may help improve prevention and treatment approaches in the future.
This is a retrospective cross-sectional study, which means it will involve reviewing existing patient records and X-rays. It will include patients who attended the clinic between November 2019 and May 2024. We will examine digital panoramic X-rays (which show all the teeth and jaws in one image) and clinical notes to identify cases that fit the study’s inclusion and exclusion criteria. Relevant demographic nformation such as age, gender, and specific details about the impacted or transmigrated tooth (including how far it moved, which side of the mouth it's on, and whether the baby tooth is still present) will be collected and analysed.
