The purpose of this study was to compare the degree of apical shift of gingival margin on inflamed gingiva by three toothbrushing techniques (modified Stillman's, roll and scrubbing method). Fifty-seven patients with mild periodontitis were used for this study. Patients were divied to three groups (19 patients for each group). Each group was instructed one of the three methods, at the beginning of the study. The position of the gingival margin was assessed on labial surface of upper and lower central incisors. At the same time, pocket depth of the labial and proximal surfaces as well as gingival and plaque index was scored. These examinations were performed at the beginning of the study, and were repeated at the 1st, 3rd, 5th, 9th and 13th week. The results of this examination were as follows. At the labial area, apical shift of gingival margin was found in all three groups. The modified Stillman's method showed the highest tendency to reduce the position of margin. Then the rolling method was followed. The scrubbing method made a minimum change on gingival margin. The bottom of the pocket, however, did not change during the period of this study in spite of difference of three brushing meshods. At the proximal areas, period of this the scrubbing method was found to significantly reduce the pocket depth when compared with other methods. The scrubbing method was the most effective on plaque removal among three brushing methods. Gingival Index scores were decreased during the period of this study, though significant differences among the three methods could not be found.
