Tidsramme
Mean Turesky Modified Quigley-Hein Index at Day 4
Tidsramme: Day 4
The Turesky Modified Quigley-Hein Index was scored on six surfaces (distobuccal, midbuccal, mesiobuccal, distolingual, midlingual and mesiolingual) to assess plaque on all gradable teeth. Whole mouth average plaque scores were calculated for each subject and tooth surfaces by totaling the scores and dividing by the number of gradable sites examined. the scoring criteria is below; (0) No Plaque; (1) Separate flecks of plaque at the cervical margin; (2) A thin, continuous band of plaque (up to 1 mm) at the cervical margin; (3) A band of plaque wider than 1 mm, but covering less than one third of the side of the crown of the tooth; (4) Plaque covering at least one third, but less than two thirds of the side of the crown of the tooth; (5) Plaque covering two thirds or more of the side of the crown of the tooth.
