Abstract

The role of dental plaque in the initiation of gingivitis has been a continuous focus of extensive study and research. In recent years, several new antimicrobial agents have been developed and investigated relative to their plaque inhibitory effects. One such product is a herbal mouthrinse containing four types of herbal extracts of Calendula officinalis. Plantago major, Fragaria vesca and Matricaria chamomilla that is currently available in Malaysia and known as Plandula. The objective of this study was to evaluate the effects of a mouthwash containing extracts of Calandula officinalis (Plandula) on the prevention of dental plaque formation and the subsequent development of gingivitis in young adult population. lor this clinical study, a group of 34 meticulously screened subjects were randomly assigned into two groups of 17 each. The first group started using the control mouthrinse tor 2 weeks followed by a washout period of 4 weeks. After this, the group used the test mouthrinse for a further duration of 2 weeks. The second group underwent the same protocol as the first except that this group started with the test mouthrinse. Measurements consisting of the following scores were recorded at baseline and after 2 weeks for each group: Plaque Index (PI) (Silness and Loe, 1964) which records the presence or absence of plaque and Gingival Index (GI) (Loe and Silness, 1963) which determines the presence or absence of gingival bleeding. Full mouth prophylaxis was carried out for all subjects after measurements at baseline as well as after the 2-week period. Hach subject was provided with a toothbrush and toothpaste. They were instructed to continue with their routine oral hygiene. They were also told to rinse with 15 ml. of the designated mouthrinse twice daily for 30 seconds each after tooth brushing. The results of* this study showed that rinsing with 0.64% Calendula officinalis in 2.56% Plandula mouthwash resulted in a statistically significant PI score difference in means of 23.9% compared to rinsing with placebo. The effect on gingivitis showed that rinsing with 0.64% Calendula officinalis in 2.56% Plandula mouthwash also resulted in a statistically significant reduction of 62.3% in mean GI scores compared to rinsing with placebo. The results seemed to indicate that mouthwash containing extracts of Calandula officinalis might have the potential of inhibiting plaque accumulation and was effective in reducing gingivitis.
