Study Summary

This study aims to investigate the impact of a bromelain pre-rinse adjunct on oral plaque removal in orthodontic subjects. The study's null hypothesis states that there is no statistically significant difference in visual plaque scores among orthodontic subjects with or without proteolytic enzyme rinse aid.

Primary Outcome

The composite plaque score refers to the cumulative plaque score of all twelve teeth following the administration of the bromelain and placebo (powdered sugar) solutions. The composite plaque score scale had a minimum value of 0 and a maximum value of 48. A score of 0 indicated no plaque was observed on the teeth, while a a score of 48 indicated severe plaque on all possible tooth surfaces. A lower plaque score reflects a better outcome, while a higher plaque score a worse outcome.

Interventions

  • DRUG Bromelain
  • OTHER Powdered sugar
