The Efficacy of Aged Garlic Extract on Gingivitis - A Randomized Clinical Trial.

OBJECTIVES: To assess gingivitis and gingival bleeding following the consumption of Aged Garlic Extract versus placebo for a period of four months.

METHODS: A randomized, controlled, examiner-blind, two-treatment parallel group study was conducted. Participants were stratified and randomly assigned equally to a regimen group using Aged Garlic Extract (AGE) or a control group, based on gender, age, baseline number of bleeding sites, and gingival health status. Assessment was performed at baseline and at one, two, three, and four months. Clinical assessment was conducted by three experienced calibrated examiners.

RESULTS: One hundred and fifty-one participants followed the inclusion criteria; 50.3% males, with an average age of 32.7 ± 8.2 years. Only 134 subjects completed the four-month study (11.3% attrition rate). A statistically significant decrease of the Modified Gingival Index and Gingival Bleeding Index scores was shown for the AGE compared to the placebo group, both between and within groups (p < 0.001).

CONCLUSIONS: This research demonstrated that daily consumption of AGE benefits oral health by reducing gingival inflammation and gingival bleeding, as compared to a placebo control.
