Modified Lobene Stain Index (MLSI) at Week 6
An assessment of the area and intensity of dental stain on the study teeth was performed using the MLSI after usage of 0.2% w/v chlorhexidine digluconate mouthwash for 6 weeks. The intensity of stain was scored on a scale of 0 to 3 (0 - no stain, 1- light stain, 2 - moderate stain, 3 - heavy stain). The area of stain was scored on the following scale: 0 - no stain; 1 - stain up to 1/3 of the area affected; 2- stain between 1/3 and 2/3 of the area affected; and 3 - stain more than 2/3 of area affected. Intensity X Area was thus analyzed on a scale of 0 (best score) to 9 (worst score).
Time frame: Week 6 post treatment administration
Overall MLSI at Week 3
An assessment of the area and intensity of dental stain on the study teeth was performed using the MLSI after usage of 0.2% w/v chlorhexidine digluconate mouthwash for 3 weeks. The intensity of stain was scored on a scale of 0 to 3 (0 - no stain, 1- light stain, 2 - moderate stain, 3 - heavy stain). The area of stain was scored on the following scale: 0 - no stain; 1 - stain up to 1/3 of the area affected; 2- stain between 1/3 and 2/3 of the area affected; and 3 - stain more than 2/3 of area affected. Intensity X Area was thus analyzed on a scale of 0 (best score) to 9 (worst score).
