[Effects of special mouth care with an aroma solution on oral status and oral cavity microorganism growth in elderly stroke patients].

PURPOSE

This study was conducted to examine the effect of oral care with an aroma solution on oral status and oral cavity microorganism growth in elderly patients with stroke.

METHODS

A non-equivalent control group, with a pretest-posttest design was used in this study. The participants were assigned to the experimental group (n=30) that received oral care with an aroma solution or the control group (n=31) that received 0.9% saline solution. To identify the effect of the experimental treatments, objective/subjective assessments of oral status and oral cavity microorganism growth were performed using the oral assessment guide, oral perception guide, and oral swab culture. Data were analyzed using Chi-square test, Fisher's exact test, and t-test with the SPSS version 21.0 program.

RESULTS

The objective oral status was significantly lower in the experimental group than in the control group (t= -3.64, p<.001). There was no significant difference between the subjective oral status of the experimental group and control groups (t= -1.24, p=.109). Oral microorganism growth was significantly lower in the experimental group than in the control group (t= -7.39, p<.001).

CONCLUSION

These findings indicate that special mouth care using an aroma solution could be an effective oral health nursing intervention for elderly patients with stroke.
