The aim of this study was to detect the presence of N-benzyl-Dl-arginase-2-naphthalamide (BANA) micro- organisms in chronic periodontitis of abutment teeth in subjects wearing removable partial dentures (RPDs) by measuring the red complex using BANA-ZymeTM test.

Materials and methods

Twenty-five subjects (mean age: 59.3 years) with Kennedy class II partially edentulous arch participated in this study. The microbiological record of red complex was done by BANA-Zyme kit and clinical parameters, such as plaque index (PI), gingival index (GI) and probing depth were recorded at abutment teeth in contact with the direct retainer of unilaterally designed RPDs and the corresponding nonabutment teeth on the opposite side.


Mean scores of BANA for the red complex, PI and GI of the abutment teeth were significantly greater than those of the nonabutment teeth (p < 0.01). No significant mean difference in pocket depth (PD) was found between the abutment and nonabutment teeth. Logistic regression analysis revealed that abutment teeth, high scores of PI and a maintenance interval longer than 6 months were significant predictors for positive red complex scores (p < 0.05).


These results suggest that the microbiological risk for periodontitis of abutment teeth is greater than that for nonabutment teeth in RPD wearers.
