Abstract: Objective To investigate the situation of gingival bleeding in patients with untreated gingivitis. Methods Totally 444 patients with untreated gingivitis were enrolled in one district located in Beijing. The gingival bleeding,except the third morlars,was evaluated using the gingival bleeding index (GBI). Results The sites of GBI=1 were 8.15±7.17 in males and 5.65±5.65 in females (P=0.0003). The sites of GBI=2 were 33.48±21.65 among subjects aged 35-50 years and 24.31±18.15 among subjects aged 18-29 years (P=0.03). The first left mandible molars had the highest GBI,while the right maxillary incisors got the lowest GBI. The posterior teeth,the lingual surface,and the proximal region had more sites than the anterior teeth,the buccal surface,and the central region on GBI=1,GBI=2 and total sites(P<0.05). Conclusion The severity of gingival bleeding is associated with age and gender,and tends to be site-specific.
