Introduction This retrospective audit assessed the treatment duration of palatally impacted canines (PICs) following surgical exposure and compares results to audits done in 2013 and 2017. This will highlight trends in treatment duration since the previous audits and also compare the results against published studies. This will aid in providing a more precise treatment plan for patients undergoing similar treatments in the future and improve efficiency especially when consenting patients to treatment duration. The prevalence of PIC by gender & unilateral/bilateral impaction will be investigated. Also explore how the patient's age, surgeon’s grade and exposure technique (open vs closed) affects the treatment duration. Methods All Patients who had their palatally impacted canines exposed between 01/01/16 until 31/12/18, and had their orthodontic treatment carried out with the orthodontic department. A data collection proforma was developed and completed on the orthodontic clinics. Data was entered into Excel & analysed. PAR scores were calculated by a calibrated clinician. Results • PIC in females (56%) vs males (44%). • Right PIC (55%) vs Left (28%) vs bilateral (17%). • 72% open exposures vs 28% closed • Unilateral PIC mean treatment duration 24 months vs 23 bilateral • Open exposure treatment duration 22 months vs 28 closed • Consultant performed exposures 27 months vs Specialty Doctor 21 months • 10 to 12 age mean duration 31 months, 13 to 15 age 23 months, 16 to 18 age 20 months. • Mean PAR reduction of 88%. Conclusion • Agrees with previous results of higher prevalence of PIC regarding gender distribution and unilateral impactions. • Unilateral impactions took longer to resolve similar to 2017 audit. • Open exposures significantly shorter duration. • Age group 16 to 18 shortest treatment duration. • High standard of orthodontic outcome as per mean PAR score • Improve note keeping & storage of casts for completeness in data collection for future.
