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-Zyme^TM test.

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.

The objective of this study is to find out the adequate porcelain thickness required for metal ceramic restorations to match the color of the shade guide and effect of repeated firing on quality and physical characteristics of dental ceramics.

Preparation of samples done first by preparing alloy substructure. A total of 15 samples of uniform thickness 0.5 mm was prepared using Ni-Cr alloy. Fusion of porcelain to alloy substructure done. Fifteen samples, five 0.5 mm thickness samples, five 1 mm samples and five 1.5 mm porcelain thickness samples were prepared. Color evaluation done by spectrophotometer.

Statistic analysis methods employed in the present study were ANOVA-one way, Scheffe's post hoc test and paired samples ‘t’ test.

The thickness of porcelain significantly affects the color of a given porcelain sample. Increasing the thickness gives better results. On repeated firings two and 10 firing did not affect the color stability.
