Importance of filament diameter when using bass brushing technique

Area of Science:

• Dentistry
• Oral Hygiene
• Biomaterials

Background:

• The Bass technique is a widely recommended method for effective plaque removal.
• Toothbrush filament diameter may influence the efficacy of the Bass technique.
• Previous studies indicated effectiveness of the Bass technique with intermediate filament diameters.

Purpose of the Study:

• To compare the cleaning effectiveness of toothbrushes with different nylon filament diameters using the Bass technique.
• To determine the impact of filament diameter on plaque removal efficacy.

Main Methods:

• A crossover experimental design was employed.
• Two types of nylon filament toothbrushes (0.132 mm and 0.280 mm diameter) were used.
• Each brush type was utilized for a 2-week period, applying the Bass technique.

Main Results:

• Toothbrushes with 0.280 mm diameter filaments demonstrated superior cleaning achievement compared to 0.132 mm filaments.
• The difference in cleaning effectiveness was more pronounced on the facial tooth surfaces.
• The previously observed effectiveness of the Bass technique in the gingival zone was not replicated in this study.

Conclusions:

• Filament diameter is a critical factor in achieving effective plaque removal with the Bass technique.
• Broader filaments are more effective than finer filaments for facial plaque removal.
• Further research may be needed to understand the nuances of filament diameter and technique interaction.
