Title: Covid 19: The impact of the new non-AGP protocol on the bracket failure rate in the Orthodontic Department at Dumfries and Galloway Royal Infirmary

Abstract:

AIM: This project looks at the impact of the new non-AGP protocol on the bracket failure rate in the
Orthodontic Department at Dumfries and Galloway Royal Infirmary.
Literature search and previous audit looking at bracket failure rate was taken into account to agree
on standard.

GOLD STANDARD was set at no more than 6%.
This project consists of retrospective audit and first cycle of prospective audit. In the retrospective
audit bracket bonding failure rate was analysed while using protocol that strictly follows
manufacturer instructions, thus generating aerosols. Prospective audit analyses bracket bonding
failure with amended bond-up protocol which avoids creating aerosols.

MATERIALS AND METHODS: All patients with full or sectional bond-ups in the analysed period of
time were included in the audit.
22 patients who had full or sectional bond-ups provided between 01/09/2019 to 31/12/2019 were
included in the retrospective audit cycle.
24 patients with full or sectional bond-ups provided between 01/09/2020 and 31/12/2020 were
included in the first prospective audit cycle.
Patients in both audit cycles were followed up for 3 months.

RESULTS:
Retrospective audit
The Gold Standard was met in the retrospective audit. 290 brackets were bonded in the
retrospective audit cycle. 15 brackets debonded within the first 3 months following bond-up. This
gives bracket failure rate at 5.2% in 3 months following bond-up when using AGP protocol.
1st cycle of prospective audit
The Gold Standard wasn’t met in the first cycle of the prospective audit.
231 brackets were bonded using amended bond-up protocol between September and December
2020. 17 brackets debonded within the first 3 months following bond-up. This gives bracket failure
rate at 7.4%, which exceeds Gold Standard figure.

CONCLUSION: Although we cannot be absolutely certain that patients' compliance hasn’t
contributed to the results due to the incomplete data, an increase in bracket failure was observed
when Covid-19 pandemic led bond-up protocol, avoiding aerosol generating procedures was
introduced.
