Brief Summary:
Diabetes and obesity affect many people in different countries. Similarly, millions of people have some type of gum disease such as gingivitis. The present study was conducted to clarify if systemic conditions such as diabetes and obesity could impair the response to gingivitis treatment. Subjects with gum disease showing diabetes type II (from 40 to 50 subjects), slight to moderate obesity (from 40 to 50 subjects) or its combination (from 40 to 50 subjects) were selected for the present study. In addition normal-weight subjects with gum disease (from 40 to 50 subjects) besides a group without gum disease (from 40 to 50 subjects) were selected for comparisons. After verbal and written explanations about the study, subjects who matched study criteria and who signed the informed consent form underwent full oral examinations in two separate visits. In the first visit, after a clinical examination to verify the levels of gingival inflammation and the accumulated amounts of dental plaque, the bone height was determined by X-Ray examinations. Bad breath was also evaluated by a chair-side apparatus. Additional laboratorial examinations included a) quantification of bacteria that cause gum disease from dental plaque samples, b) quantification of inflammatory products from gingival fluid sampling and c) quantification of produced saliva. Self-report questionnaires were used to check the impact of oral condition and treatment of gum disease in quality of life and individual daily performance. These examinations were repeated 3 months after dental treatment. All subjects received ultrasonic dental prophylaxis for cleaning their teeth. Based on systemic/oral conditions each group rinsed either an essential-oils containing mouth rinse or a placebo rinse. First rinse was supervised and the other ones were performed at home twice a day for three months. Each participant also received a toothbrush, a dental floss and a fluoride toothpaste monthly after oral hygiene instructions. Adherence to the treatment and occurrence of undesirable side effects were monitored throughout the study.

Drug Information available for: Listerine

Arm Intervention/treatment
Experimental: Ultrason Essential oils rinse
Ultrasonic debridement followed by twice daily home use of an essential-oils mouth rinse (20mL, 30 seconds for each rinse) for 3 months
Other: Ultrason Essential oils rinse
Test treatment strategy combined mechanical and chemical procedures. Mechanical procedures were: a) ultrasonic debridement to remove dental plaque, calculus and teeth staining; b) dental polishing and c) oral hygiene instructions related to brushing and flossing. Toothbrush, dental floss and fluoride dentifrice were monthly provided. Within the same visit participants performed at the study center the first supervised rinse. Other rinses were performed at home unsupervised. A diary card was used to register times of rinsing. Participants rinsed twice a day a commercially available non-prescription essential-oils solution (20mL, 30 seconds for each rinse) for 3 months. This solution is composed of eucalyptol 0.092%, menthol 0.042%, methyl salicylate 0.060%, thymol 0.064%, zinc chloride and sodium fluoride 0.0221%.
Other Name: Listerine total care

Placebo Comparator: Ultrason Placebo rinse
Ultrasonic debridement followed by twice daily home use of a placebo rinse (20mL, 30 seconds for each rinse) for 3 months
Other: Ultrason Placebo rinse
Comparative treatment strategy combined mechanical and chemical procedures. Mechanical procedures were: a) ultrasonic debridement to remove dental plaque, calculus and teeth staining; b) dental polishing and c) oral hygiene instructions related to brushing and flossing. Toothbrush, dental floss and fluoride dentifrice were monthly provided. Within the same visit participants performed at the study center the first supervised rinse. Other rinses were performed at home unsupervised. A diary card was used to register times of rinsing. Participants rinsed twice a day a placebo solution (20mL, 30 seconds for each rinse) for 3 months.
Other Name: Placebo mouth rinse manipulated for the present study.




Primary Outcome Measures :
  1. plaque and gingival indices [ Time Frame: 3 months ]
    percentage of dental surfaces showing mild (scores 0,1), moderate (scores 2,3) or severe (scores 4,5) amounts of dental plaque or showing gingival bleeding (positive or negative) after gentle probing
