Objective: This study aims to compare the effects of an Essential-Oil mouthrinse (EO) and a Delmopinol mouthrinse (DM) on gingival bleeding and dental-plaque in healthy adults.

Methods: Ninety subjects entered were selected to participate in the clinical trial (49% males and 51% females; mean age of 32.3 years), with a minimum of 6 teeth per quadrant and periodontal pockets depth less than 5 mm. Every patient received a dental hygiene appointment. After the appointment, subjects were allocated to one of three study groups: Group 1 - Cool Mint Listerine (EG); Group 2 – Decapinol (DG); Group 3 – Control (no mouth rinse). Mouth rinse groups were asked to use the solution for two weeks, following manufacturer’s instructions. Gingival bleeding was accessed using the Gingival Index (GI), and Dental Plaque was accessed by the Quigley-Hein-Turesky Index.

Results: There were no baseline differences between groups regarding dental plaque and bleeding indexes. For GI, only the DG group had statistically significant lower scores than the Control group (p<0.05), with 33.8% difference. DG and EG results were not statistically different. For Plaque Index, only the EG group had a statistically significant lower index score than the Control group (p<0.05). EG and DG did not statistically differ.

Conclusion: There was a statistically significant reduction in GI scores for DG group vs. Control group and a statistically significant reduction of Dental Plaque index score in the EG vs. Control. EG and DG groups did not differ between them for both indexes scores. Although statistical significance was attained, clinical significance may not be of consequence.
