An evaluation of proximal surface cleansing agents.

The effectiveness of the Interspace brush, Inter-Dens, and waxed dental floss as proximal surface cleansing agents was compared in 35 subjects. Each subject used all three methods of cleansing in random order of selection. Statistical analysis of the results showed that there was no difference in the effectiveness of any one of these three agents. However, proximal surfaces of anterior teeth where cleaned more effectively than posterior teeth. The coronal half of the proximal surfaces was cleaned more effectively than the apical half and the facial half more effectively than the lingual half when Inter-Dens was used. Comparison of cleansing effectiveness between facial and lingual halves of proximal surfaces for the Interspace brush and waxed dental floss showed no significant difference. Mesial and distal proximal surfaces were cleaned with similar effectiveness. Plaque control was only satisfactory on approximately half of the proximal surfaces, though a wide variation occurred. Significantly lower plaque scores were found 1 week after the initial instruction session, irrespective of the agent used. The majority of subjects preferred Inter-Dens whilst waxed dental floss was the least-liked method of cleansing.
