OBJECTIVES: Gingivitis is defined as lesions on the gingival margin, expressed through gum redness, bleeding, localized edema, and gingival sensitivity. It is most often caused by substances produced by bacterial plaque, or dental biofilm, which develops along the gingival crevice.To evaluate, using patient’s interview results, the quickness of action of several treatments for gingival inflammation. METHODS: Observational, prospective, longitudinal, multicentric study carried out in  France, using data collected by participating dentists and dental surgeons. RESULTS: A total of 316 patients with gingivitis returned their questionnaire. women: 65.25%, current smokers:22.93%  and 28.51% were ex-smokers.

Finally, 62.26% had previous history of gingivitis symptoms. As for dental surgeons: 96.36% had performed scaling, 15.15% gingival curettage, and 13.64% radicular resurfacing. A total of 78.4% judged gingival inflammation to be moderate to severe, 63.10% said it had spread (>30%). In terms of treatment: 98.62% gave patients oral hygiene advice, 87.98% advised on brushing methods, 69.91% recommended specific toothpaste, and 78.85% a mouthwash. A total of 30.61% had generalized inflammation after 1 month, reducing to just 11.24% at 2 months and 15.63% at 3 months. A total of 88.08% reported improvement in inflammation after the first month, 91.59% at 2 months and 93.59% at 3 months. A total of 83.93% felt less pain after 1 month of treatment, 87.90% after 2 months and 92.08% after 3 months.(p=0.0418). 89.13% felt their treatment was effective after 1month, 97.79% after 2 months and 96.15% after 3 months.(p=0.0036). CONCLUSIONS:  In terms of satisfaction, 86.52% were satisfied after 1 month, 94.85% after 2 months and 95.92% after 3 months. (p=0.0076). 87.57% felt their treatment was easy to follow after 1 month, 86.76% after 2 months and 92.08% after 3 months. Above all, after the first month of treatment, 88.83% said they would continue using the treatment in prevention even after complete disappearance of gingivitis.
