Aim: The aim of this study was to evaluate the antiplaque effect of Lippia sidoides (LS) by in vivo investigation. Materials and Methods: Ten healthy volunteers participated in a cross-over, double-blind clinical study, using a 3-day partial-mouth plaque accumulation model. The participants abolished any method of mechanical oral hygiene and they were randomly assigned initially to use just the following mouth rinses: Distilled water (negative control group), 0.12% chlorhexidine digluconate (positive control group) or 10% LS (test group). The plaque index was recorded in the six anterior upper teeth at the end of the trial and the one-way ANOVA and Bonferroni tests were used to estimate the difference among groups. Results: The clinical results did show statistically significant difference among three groups (P < 0.05), favoring the positive control group and test group, however, no difference in efficacy was found between them (P > 0.05). Conclusions: The mouth rinses containing 0.12% chlorhexidine digluconate and 10% LS were equally able to inhibit plaque re-growth.

Objective: To determine the epidemiological profile of elderly women with burning mouth symptoms. Methods: A cross sectional, quantitative, exploratory and descriptive study conducted in two phases: a) determining the prevalence of burning mouth symptoms among 263 elderly women aged between 60 and 83 years who attended six public municipal community centers in Fortaleza-CE, Brazil, b) defining the epidemiological profile of respondents with burning mouth symptoms, through the variables: self-reported diseases, salivary flow, use of medications, dental prosthesis and oral hygiene habits. Data were organized by the Statistical Package for Social Sciences - SPSS version 15. Results: The prevalence of burning mouth symptoms in the group was 19% (n=50). Of these, 41 (82.0%) reported the manifestation of the symptoms as a scalding sensation. Regarding the occurrence, the most referred sites were: tongue (48%; n=24) and gums (22%; n=11). Among elderly women, 24 (48.0%) had daily symptoms. Regarding self-reported diseases and habits: 80.0% cited cardiovascular diseases, 74.0% (n=37) musculoskeletal illness and 62.0% (n=31) neurological disorders, besides 56.0% (n=28) present reduction of salivary flow; 70.0% (n=35) took medication, 66.0% (n=33) were users of dental prosthesis and 18.0% (n=9) did not brush their teeth. Conclusions: The prevalence of burning mouth symptoms in this group was 19%; scalding sensation was the main manifestation of the symptom and the tongue was the site of major symptomatology. The epidemiological profile of symptomatic elderly was distinguished by self-reported diseases and habits such as cardiovascular, musculoskeletal and neurological disorders, in addition to reduced salivary flow, as well as the use of medications and dental prosthesis.

The effect of Aloe vera on the reduction of plaque and gingivitis was evaluated in a randomized, parallel and double-blind clinical trial. Subjects were randomly allocated to the test group (n=15) - dentifrice containing Aloe vera - or the control group (n=15) - fluoridated dentifrice. Plaque index (PI) and gingival bleeding index (GBI) were assessed at days 0 and 30. Subjects were asked to brush their teeth with the control or test dentifrice, three times a day, during a 30-day period. There was a significant reduction on plaque and gingivitis in both groups, but no statistically significant difference was observed among them (p>0.01). The dentifrice containing Aloe vera did not show any additional effect on plaque and gingivitis control compared to the fluoridated dentifrice.
