Plaque removal by the Bass and Roll brushing techniques
Journal of Periodontology
|August 1, 1977
Summary
The Bass technique showed better plaque removal near gums than the Roll method, but overall effectiveness was poor. Even with repeated instruction, dental students struggled to achieve acceptable tooth cleaning standards.
Area of Science:
- Dental Hygiene
- Preventive Dentistry
Background:
- Effective plaque removal is crucial for preventing gingivitis and periodontal disease.
- Dental students require optimal instruction in plaque removal techniques.
Purpose of the Study:
- To compare the effectiveness of the Bass technique versus the Roll method for plaque removal.
- To evaluate the efficacy of a single instructional session on tooth cleaning competence.
Main Methods:
- A crossover study design involving 38 junior dental students.
- Comparison of plaque removal using Bass technique and Roll method on lingual and facial tooth surfaces.
Main Results:
- The Bass technique demonstrated superior plaque removal adjacent to gingival tissues compared to the Roll method.
- No significant difference in overall plaque removal effectiveness between the two techniques.
- Overall tooth surface cleaning remained at an unacceptable level.
Conclusions:
- Single-visit instruction, including demonstration, is insufficient for achieving efficient tooth cleaning.
- Repetition of instruction within three weeks did not significantly improve plaque removal standards.
