Plaque-induced gingivitis is a reversible inflammatory reaction of the marginal gingiva to plaque accumulation. Removal of dental plaque is recognized as advantageous in the maintenance of gingival health and prevention of periodontal disease. The aim of the present study was to evaluate the effect of combination of chlorhexidine mouth wash and tooth paste versus chlorhexidine mouth wash only and also versus chlorhexidine oral gel only in plaque induced gingivitis. Forty five adult patients participated in this study, manifested signs and symptoms of plaque inducing gingivitis, none of them had loss of periodontal attachment. The patients were allotted into three groups,15 patients in each group . The first group were used chlorhexidine tooth paste with tooth brushing . They also used chlorhexidine mouth wash for two weeks.The second group were used chlorhexidine mouth wash only for two weeks. The third group were used chlorhexidine dental gel for two weeks. Plaque index and gingival index were recorded before treatment and again after 1 week and 2 weeks of therapy. Also, plaque samples were obtained for bacteriological study. Regarding the comparison between Plaque index and gingival index score of the study groups, the results of the present study revealed that there was a statistically significant difference between group I and group II , group I and group III ; but there was no significant difference between group II and group III after 1 week and 2 weeks although chlorhexidine mouthwash was more effective than chlorhexidine oral gel. In the present study the comparison between study groups as regard the bacterial count stated that there was a statistically significant difference between group I and group II , group I and group III and there was no statistically significant difference between group II and group III after 1 week and after 2 weeks.
