Summary

This randomized crossover clinical trial evaluated whether the sequence of powered toothbrushing and dental flossing affects dental plaque removal. Forty-six systemically and periodontally healthy participants were randomly assigned to one of two oral hygiene sequences. In Group 1, participants performed powered toothbrushing followed by dental flossing during the first period and dental flossing followed by powered toothbrushing during the second period. Group 2 performed the same procedures in the opposite order. The two intervention periods were separated by a 15-day washout period, with professional prophylaxis performed to standardize oral hygiene conditions. Dental plaque was assessed before and after the oral hygiene procedures using the Plaque Index (PI) and the Turesky modification of the Quigley-Hein Plaque Index (TQHPI). The study aimed to determine whether performing powered toothbrushing before or after dental flossing results in greater plaque removal.
