Abstract
Dental caries is one of the most common chronic infectious diseases in the world, which remains a major problem in both developed and developing countries. Streptococcus mutans is the most common related bacteria in its etiology. Mouth rinses are one of the methods used in prevention of dental caries. Nowadays herbal mouth rinses can be used instead of chemical mouth rinses as Chlorhexidine. So the objectives of this study was evaluating the antimicrobial efficacy of the herbal mouth rinses and the patient’s satisfaction to those mouth rinse.
The present study was carried out on 84 children. Children were recruited based on certain inclusion criteria after signing a written informed consent by their parents. They were divided into 4 groups. group (I) the children rinsed with Chlorhexidine mouth rinse, the child rinsed for 1 minute and plaque samples were collected from the child before and after rinsing. group (II) children rinsed with green tea extract, while group (III) children rinsed with garlic with lime extract and group (IV) the children rinsed with pomegranate extract mouth rinse with the same procedures.Child satisfaction was measured using 5-point pictorial likert scale which is graded from 1 to 5 (1.Excellent.2.Good.3 Average 4.Poor. 5. Very poor).
All the plaque samples were collected and put in sterile test tubes containing thioglycolate as a transport media. They transferred to the microbiology laboratory within half an hour after rinsing for detection of bacterial counts. These samples were incubated 48-96 hours at 37°C. Number of bacterial colonies were counted by hand-held digital colony counter. Intergroup and intragroup comparisons were carried out. Results revealed that there was a significant difference between different groups (p<0.001). The highest value was found in Garlic-lime group, followed by Chlorhexidine, then Green tea and the lowest value was found in the Pomegranate group. Post hoc pairwise comparisons showed Garlic-lime to have significantly higher value than other groups except for Chlorhexidine (p<0.001). In addition, they showed Chlorhexidine to have significantly higher value than Pomegranate (p<0.001).
Intra group comparison showed that for all groups of the mouth rinses, there was a significant decrease of bacterial count after treatment (p<0.001). Results showed that for parameters (smell, taste and willing to use again), there was a significant difference between different groups. Garlic-lime having significantly lower value than other groups (p<0.001).This shows that although the Garlic mouth rinse has an antimicrobial efficacy it had unacceptable taste and smell to the children.
By analyzing these results, it showed that there is an antimicrobial efficacy for all these herbal mouth rinses compared to Chlorhexidine but it is much higher for pomegranate extract mouth rinse. Children acceptance was also affected by some factors as taste and smell of the mouth rinses.
