In India legislation prohibits the use of tobacco as an ingredient in dental care products.1 Such products, in the form of powder or paste, are applied most commonly with the index finger to teeth and gums. Various tobacco products are used as dentifrice in different parts of India.2 3 We are not aware of any reports covering such a use of tobacco products (in contrast to chewing and smoking) especially among adolescents.4 5
Participants, methods, and results
The global youth tobacco survey focuses on school students aged 13-15 and uses standardised methods.4 In India the survey is being conducted independently in each state. We report on the prevalence of the use of tobacco products as dentifrice in 14 states listed in the table, with sample sizes ranging from 2067 to 5245 students.
We selected a two stage probability sample of students in grade 8-10 (which corresponds to 13-15 years in age) in each state and conducted a survey among students with an anonymous, self administered, close ended questionnaire. Participants were asked to include a maximum of five products, which could differ from state to state. A pilot tested questionnaire for India contained a specific question on application of tobacco products (in addition to chewing), and a positive response identified the use of a tobacco product as dentifrice. We defined current use as use within 30 days preceding the survey.
The overall response rate was over 80% except in Bihar (70%) and Maharashtra (79%). The proportion of boys was between 50% and 55% in the different states.
The use of tobacco products as dentrifice varied from 6% (Goa) to 68% (Bihar). The prevalence among boys was notably higher than among girls in Orissa and Uttaranchal, marginally higher in nine states, and marginally lower in three states. Of the specific products, tobacco toothpaste (creamy snuff) and tooth powder (lal dant manjan) were common in all states (table). Gul (a pyrolysed tobacco product) was used in eight states. Other dentifrice products containing tobacco were: mishri (roasted and powdered tobacco) and dry snuff (bajjar or tapkir) in Goa and Maharashtra; gudakhu (paste of tobacco and molasses) in Bihar, Orissa, Uttar Pradesh, and Uttaranchal; and tobacco water (tuibur or hidakphu, manufactured by passing tobacco smoke through water) in Manipur, Mizoram, Sikkim, and Tripura. It is used for gargling, not drinking.
Many students in India use tobacco products as dentifrice. Differences between the sexes were minimal and similar to those reported globally.5
In India the misconception is widespread that tobacco is good for the teeth. In a study reported from Ernakulam district in Kerala 92% (3013) of 3261 female tobacco users and 28% (2159) of 7575 male users specified tooth related problems as the reason for starting to use tobacco.3 Many companies take advantage of this misconception by packaging and positioning their products as dental care products. A laboratory test of five samples of red tooth powder that did not declare tobacco as an ingredient found a tobacco content of 9.3-248 mg per gram of tooth powder.
The 1992 amendment to India's Drugs and Cosmetics Act 1940 barred manufacturers from using tobacco as an ingredient in any toothpaste or toothpowder. One manufacturer challenged this amendment, but ultimately the Supreme Court passed judgment in favour of the government of India.1
We carried out our study 10 years after the law had been amended. Surprisingly, 6-68% students still reported that they currently used products containing tobacco for oral care, which shows clearly that the regulations have not been implemented adequately.
This study was carried out in technical collaboration with the US Centers for Disease Control. The global youth tobacco survey in Maharashtra was done by Surendra Shastri and in Goa by the late S G Vaidya, and we are grateful for their permission to use their data. We wish to acknowledge the contribution and help from Samira Asma and Charles Warren.
Contributors DNS conducted fieldwork in 12 of the 14 states included in this study and wrote the first draft.

Ethical approval The study design was evolved and approved by the World Health Organization in Geneva, Switzerland, and the Centers for Disease Control and Prevention in Atlanta, USA. The surveys were conducted with their collaboration. The study satisfied ethical criteria specified by the Indian Council of Medical research. Appropriate permission from the state education authority and the principal of each school was obtained. The study design did not fall within the scope of studies that require clearance by the internal review board of the Tata Memorial Hospital. The other institutions do not have their own internal review boards.
