| Introduction|| |
Mouthwash has been used for centuries for medicinal and cosmetic purposes, but in recent years, the rationale rationale behind the use of chemical ingredients has been subjected to scientific research and clinical trials. Ayurveda is considered as the “science of life.” The ancient Indian system of health care focused on views of man and his illness. Long before the advent of modern medicine, herbs were the mainstream remedies for nearly all ailments. Herbal medicines were in great demand in the developed as well as in developing countries for primary health care because of their wide biological and medicinal activities, higher safety margin, and lower costs.
The World Health Organization estimates that about 80% of the populations living in the developing countries rely almost exclusively on traditional medicine for their primary health-care needs. Conventional drugs usually provide effective antibiotic therapy for bacterial infections, but there is an increasing problem of antibiotic resistance and a continuing need for new solutions. Hence, nowadays, herbal drugs are preferred to synthetic antibiotics.
Natural herbs such as triphala, tulsi patra, jyestiamadh, neem, clove oil, pudina, ajwain, and many more used either as whole single herb or in combination have been scientifically proven to be safe and effective medicine against various oral health problems such as bleeding gums, halitosis, mouth ulcers, and preventing tooth decay.
Triphala' is a well-known powdered preparation in the Indian System of Medicine, being used in Ayurveda since ancient time. Triphala consists of equal parts of the Emblica officinalis (Amalaki), Terminalia chebula (Haritaki), and Terminalia belerica (Bibhitaki).
T. chebula is valuable in the prevention and treatment of several diseases of the mouth such as dental caries, spongy and bleeding gums, gingivitis, and stomatitis. The extract could successfully prevent plaque formation on the surface of the tooth, as it inhibited the sucrose-induced adherence and the glucan-induced aggregation, the two processes which foster the colonization of the organism on the surface of the tooth. Thus, the extract of T. chebula may be an effective agent in the treatment of carious teeth, owing to its ability to inhibit the growth and accumulation of Streptococcus mutans on the surface of the tooth. This would prevent the accumulation of acids on the surface of the tooth and thus the further demineralization and the breakdown of the tooth enamel.
Antimicrobial and antioxidant effect of triphala has been proven in vitro as it has been shown to inhibit S. mutans at concentrations as low as 50 μg/ml. This antiplaque effect probably may be due to the tannic acid in triphala, which is adsorbed well to the groups on the surface of the bacterial cells, which result in protein denaturation and ultimately to bacterial cell death.
Triphala presented an antiplaque efficacy similar to that of chlorhexidine (CHX) and was more effective in inhibiting plaque formation with lesser or no side effects.
CHX is a dicationic bisbiguanide which is effective against an array of microorganisms including Gram-positive and Gram-negative bacteria, fungi, yeast, and viruses. It is regarded as the “gold standard” antiplaque treatment and is particularly effective against gingivitis. It is generally used at a concentration of 0.2% (0.12%). However, most practitioners do not recommend the long-term and daily use of CHX as mouthwash. This is mainly because of its side effects such as objectionable taste, tooth discoloration, desquamation, and soreness of oral mucosa.
To overcome the disadvantages of CHX, other agents may have to be used as mouthwash. Triphala extract mouthwash may be an alternative in such a scenario with no reported adverse effects.
Hence, this study was undertaken to evaluate the effect of 0.6% triphala extract mouth rinse and to compare the effect with 0.12% CHX mouth rinse against plaque accumulation and gingival inflammation among 18–24 years study participants.
| Materials and Methods|| |
A double-blinded parallel arm randomized controlled trial was conducted to assess the effect of 0.6% triphala and 0.12% CHX on oral health and to compare the effect of triphala with CHX and control group regarding plaque accumulation and gingival inflammation.
Ethical clearance was obtained from the Institutional Review Board, and Informed consent was obtained from the study participants.
Data were collected from 18 to 24 years age female undergraduates residing at V. S Dental College Ladies Hostel, Bengaluru, based on inclusion and exclusion criteria.
- Participants with the age group of 18–24 years female undergraduates with minimum of 20 teeth
- Participants with gingival and plaque index (PI) score of ≥1 in 10% of the sites
- Participants who are willing to comply with the appointment schedule.
- Participants with any systemic conditions
- Participants with any allergy or infectious diseases
- Participants receiving antibiotic therapy or any medication within the past 6 months
- Participants already using any mouth rinse
- Participants wearing an orthodontic appliance or removable partial denture.
All the female undergraduate students of the womens hostel were screened. The selected sixty participants were randomly allotted to three groups of twenty participants in each group using lottery method. Group 1 - Triphala, Group 2 - CHX, and Group 3 - Control group.
Sample size determination
Simple random sampling method was followed. Based on the secondary data, the sample size was estimated to be 60.
Sample size calculation using the formula:
n = 19.35
Δ Confidence interval - 95% (0.95),
Power = 80% (0.80), ZD = Z0.95 = 1.96, Zβ = Z0.80 = 0.84, Δ2 = 0.9 (expected difference).
The estimated sample size was 19 and this was rounded off to 20 for each group, and total sample size was 60.
Preparation of the mouth rinse
Commercially available triphala powder was taken. An alcoholic extract of triphala was obtained using cold maceration technique with 97% ethanol as the solvent. Ten percent triphala mouth rinse was prepared by adding 100 g of the extract to 1 L of sterile distilled water. Commercially available 0.2% CHX solution (Hexidine ICPA Health products; Mumbai, Maharashtra, India) was diluted to a 1:1 concentration. Sterile distilled water with coloring agent was used as the control. All the mouth rinses were freshly prepared every week at Visveswarapura Institute of Pharmaceutical Sciences College, Bengaluru. Solutions were made of identical color and taste to eliminate bias. The contents of the solutions were known to the person who prepared the solution and were disclosed to the investigator at the end of the study.
Method of data collection
The study was conducted during the period of June 2015 for a period of 21 days.
Demographic information and oral examination were done to record the gingival index (GI) and PI, according to Loe and Silness and Silness and Loe criteria to assess the plaque accumulation and gingival inflammation at baseline.
The mouth rinse was given to the participants, and instructions were given about the procedure to use 10 ml twice daily for 30 s for 21 days and refrain from eating or drinking for 30 min after using the mouth rinse. Mouth rinsing was performed daily without any direct supervision.
During the entire study period, the participants continued to exercise their routine self-performed oral hygiene measures. No instructions were given to any of the participants regarding the oral hygiene practices, so as to prevent any associated bias in any of the groups. Participants were reexamined after 21 days, and oral examination was done to record the gingival and plaque scores by the same examiner [Figure 1].
Data collected during the study were entered into excel sheets and were subjected to data analysis. Statistical analysis was done by Statistical Package for Social Sciences (SPSS) version 16(Chicago, USA SPSS Inc.) for descriptive data analysis. Descriptive statistics was done for demographic data. The Analysis of Variance (ANOVA) test was used to find the significant differences between the means of the study groups with P< 0.05 and Wilcoxon signed-rank test was used for the comparison of baseline and postrinsing within each group.
| Results|| |
All the study participants (n = 60) who completed the study were females with a mean age of 20.23 years. Mean PI score according to Sillness and Loe index for each group was recorded at the baseline. The mean score for triphala group was 1.231 (standard deviation [SD]: 0.21), CHX 1.2215 (SD: 0.188), and control 1.229 (SD: 0.19). There was no statistically significant difference [Table 1].

| Discussion|| |
A randomized controlled trial was done to evaluate the effect of 0.6% triphala extract and compare with 0.12% CHX mouth rinse on dental plaque accumulation and gingival inflammation. Study participants were randomly allocated into three groups. Clinical examination was done to record plaque and gingival scores at baseline and postrinsing. This is in accordance with the study conducted by Bajaj et al.
The purpose of recording was to observe any soft tissue changes such as increase or decrease in inflammation occurring due to the use of agent. Plaque and gingival scores were recorded for all participants on day 0 and 21 by trained examiner. The effect of triphala extract mouth rinse was intended to be studied in a real life situation and hence no oral prophylaxis was performed. This is in accordance with the study conducted by Chainani et al.
Several authors have used triphala as a mouth rinse in healthy gingivitis and periodontitis patients., Triphala presented an antiplaque efficacy similar to that of CHX and was more effective in inhibiting plaque formation with lesser or no side effects.
Sushruta Samhita has emphasized that triphala has hemostatic, anti-inflammatory, analgesic, and wound-healing properties. Haritaki is the most efficacious for bleeding gums and gingival ulcers as well as carious teeth. On the other hand, Amalaki contains a large amount of Vitamin C, which is the most effective in preventing bleeding from gums.
Jagadish et al. conducted a study to determine the effect of triphala on dental biofilms and concluded that triphala had potent antioxidant and antimicrobial activity and inhibited the growth of S. mutans and Gram-positive cocci involved in plaque formation when it was adsorbed on the tooth surface.
Bhattacharjee et al. conducted a study to evaluate the efficacy of triphala mouth rinse (aqueous) in the reduction of plaque and gingivitis among children and concluded both CHX and triphala groups showed significantly lower mean gingival and PI scores at follow-up than baseline (P < 0.001), and no significant difference in the percentage change in the mean GI between the two groups (P = 0.826). The percentage change in the mean PI was significantly higher in the CHX group compared to the triphala group (P = 0.048).
Tandon et al. suggested the use of triphala mouthwash for preventing the development of incipient lesions and reported that triphala mouthwash is cheaper than the commercially available CHX mouthwash. Being an ayurvedic product, it has no side effects and hence is safer for long-term use.
Effectiveness of CHX can be attributed to its bactericidal and bacteriostatic effects and its substantivity within the oral cavity (8 h after rinsing) CHX has often been used as a positive control. Hence, 0.12% concentration was used in this study as there were fewer side effects compared to 0.2%. In CHX group, mean plaque and gingival scores are 1.22 ± 0.18 and 1.23 ± 0.298 at baseline and 0.92 ± 0.26 and 0.94 ± 0.37 at postrinsing. There was a significant reduction in the scores with P< 0.009 at baseline and postrinsing. This is in accordance with the study conducted by Moran et al. and Quiren et al., in which CHX was found to be effective in reducing plaque and gingival scores.
In the triphala group, patients did not complain about any side effects and had no adverse effects and was readily available at affordable prices in this geographical location for future use. CHX has been considered the best antiplaque and antigingivitis agent, but now, it is time to acknowledge the value of natural herbs such as triphala, known to have many useful properties and no side effects.
The present study was conducted among dental students (girls) of relatively younger age group. However, their selection was based on the relevant inclusion and exclusion criteria to keep bias at the minimum.
The study should include both the genders.
