# Introduction ral diseases are a major public health concern due to their increased prevalence and their effects on people's quality of life. 1 They affect people throughout their lifetime, causing pain, discomfort, disfigurement, and even death. As per the estimation to the World Health Organization (WHO), oral disease affects nearly 3.5 billion people worldwide. 2 Tooth decay (untreated dental caries), severe O periodontal (gum) disease, and oral cancer are the most prevalent dental diseases affecting the global population. An unhealthy diet with high sugar content, use of tobacco, high consumption of alcohol, and poor oral hygiene are the common factors affecting the oral health of people. 2,3 Dental caries results when plaque (a sticky film of bacteria and food) formed on the surface of a tooth converts the free sugars into acids, which when not removed on a daily basis, slowly destroys the enamel surface of the teeth, causing cavities. Continued high consumption of free sugar and tobacco and inadequate exposure to fluoride leads to increased cavities, pain, bad breath, gum irritation resulting in gingivitis, periodontal disease, and tooth loss. 4 tobacco use is a major risk factor of noncommunicable diseases such cancer (NCDs), making it one of the biggest public health threats the world has ever faced 5 . Similarly, accessibility of treatment service for an oral health condition, education, and sociodemographic environment also influence oral hygiene practices 6 . Treatment services for oral health conditions are rarely available in rural areas and mostly confined to urban areas but is expensive, not all the population of low-income countries like Nepal can afford. Promotion of oral health is the only cost-effective approach that can address the overall population to maintain oral health, prevent the burden of oral disease, and promote an individual's quality of life. A large ratio of oral diseases can be prevented by providing education on oral hygiene, which includes a consequence of tobacco smoking, high consumption of sugar-containing diets along with the importance of brushing teeth with a fluoride-containing toothpaste and flossing, which eventually enforces the general population to improve their attitude towards oral health and hence apply in their daily life. 5, 7 There have been very few studies in Nepal that have addressed this issue. Keeping this background in mind, the present study was conducted to assess oral hygiene practices, tobacco use, and food habits of people among the Tharu community of Gadi rural municipality, Sunsari, Nepal. Types of tobacco use, their quantity, and food habits of participants were reported in the data collection form. The English language questionnaire was translated into Nepali for an easy understanding of the study population. Collected data were checked for completeness, entered in Microsoft Excel, and then analyzed using IBM-SPSS 17 (IBM Corporation, Armonk, NY, USA). Descriptive statistics were used. Ethical approval for this study was obtained from the Ethical Review Board (ERB) of the concerned authority. Written permission for conducting the study was taken from the administrative section of the Gadi Rural Municipality, Sunsari, Nepal. Written informed consent was obtained from the participants before enrolling them in the study. Participants were fully informed about the nature and purpose of the study in the Nepali language. Personal details provided by the participants were kept confidential and anonymity was maintained. # Volume XX Issue IX Version I III. # Results The demographic characteristics of the participants have been depicted in Table 1. More than half of the participants were in the age group of 18-35 years (53.45%). Females were predominant (57.9%) in this study. The majority of the participants were married (133, 83.6%), while 7(4.4%) were widows/widowers. Among the total participants, 33 (20.8%) of them had never gone to school and the majority of patients 68 (42.8%) had received a secondary level of education. Similarly, 111(69.81%) of them were unemployed, and more than half (52.2%) belonged to a nuclear family. The majority (50.9%) of the participants had 5-8 members in their family. All participants acknowledged brushing their teeth. The majority of the participants used fluoridated dentifrices (115, 80%), while 15 (10.5%) of the participants did not know about their dentifrices. Most of the participants (84.3%) cleaned their teeth in the morning, and 2 (1.3%) of them responded that they have no any fix time for cleaning their teeth. Almost 3/4 th (73%) of the participants used toothpicks as an oral hygiene aid for cleaning their teeth. No other cleaning equipment's like dental floss and interdental brush was used in the community. Approximately 4/5 th (81.76%) of the participants cleaned their teeth once daily, while 15% cleaned them twice daily. The majority of the participants (86.8%) used toothbrush and toothpaste, whereas a few (6.3%) of them used Datiwan (historic plants like neem and babool twigs used for brushing) as a means for cleaning their teeth. one hundred and nineteen (75%) participants disclosed that they change their toothbrush twice a year, as shown in Table 2. Of the total 159 participants, one-third (29.6%) of them used any type of tobacco substance followed by tobacco leaf (22, 46.8%), cigarette (21, 44.5%), Chilim/Hookah (2, 4.2%), and Gootka (2, 4.2%), respectively, as illustrated in Table 3. The food habits of the participants has been unveiled in Tables 4a and 4b. Of the 159 participants interviewed, the majority (50.9%) of the participants eat fresh fruits several times a month followed by several times a week (18.2%) and once a week (5.7%), respectively, while very few 1.3% of the participants never eat fresh fruit. One-third of the participants (32.1%) eat junk food several times a month while only 10.1% of participants never used junk food. The majority (54.7%) of participants drink soft drinks (Lemonade, Coca Cola, and Fanta) several times a month, and 21.4 % never had the habit of consuming soft drinks. Most of the participants (90%) had no habit of consuming food items like jam/honey, while 10% of them have a habit of consuming jam/honey several times a month. Most of the participants (42.1%) eat sweets and candy several times a month, followed by once a week (17%), while 27.7% of participants never had the habit of consuming such items. About half (46.5%) of the participants had no habit of drinking milk with sugar. Participants who drank milk with sugar once a day were 17.6% , followed by several times a week (13.2%), several times a month (13.2%), and very few (1.3%) of them had the habit of drinking milk with sugar several times a day. More than one-third (35%) of the participants drink tea with sugar once a day followed by several times a day (26.4%), several times a week (10.7%), whereas 18.2% of them had no habit of taking tea with sugar. Tea and coffee drinking habit was also less among Tharu i.e. 1.3% takes coffee several times a month. Our study studied the oral hygiene practices, tobacco use and food habits in the Tharu community of Gadi rural municipality over a period of seven months among 159 participants. Most of the participants were female with an average age of 39 years. Our study showed that more than four-fifth (81.6%) of the Tharu people (the indigenous people) brush their teeth once a day and 15% of participants brush their teeth twice daily to maintain dental health. Most of the participants (86.8%) used a brush and toothpaste for brushing their teeth. Our findings were in contrast with the findings of indigenous people of Australia, where culturally and timely appropriate dental care was deficient among the Indigenous people. 5 Datiwan (historic plant-like neem and 3.1% of the participants used Karchi (bamboo twigs) to brush their teeth, which was similar to the findings of indigenous people of Assam India where datiwan and bamboo twigs were used for brushing teeth, but the species of plants used for brushing teeth was found more in number among the indigenous people of Assam, where 83 different plant species belonging to 37 angiosperm families were used for brushing teeth to maintain oral health and hygiene among the indigenous communities. 8 Our study found that almost one-third (29.6%) of the Tharu (Indigenous people of Nepal) people used any type of tobacco substance, which is less than Tobacco used among Australian indigenous people, where 39% of the indigenous people used tobacco. 4 Tobacco consumption was shown less in our study, which might and babool twigs used for brushing) was used by 6.3% It is well-known truth that fresh fruits promote oral health. In several studies, fresh fruit consumption was significantly associated with a reduced risk of oral health problems. 9, 10 Higher consumption of fresh fruits had an independent strong positive association with oral health-related quality of life. 11 In our study, the majority (50.9%) of the Tharu people eat fresh fruits several times a month. Excess amount of sugar consumption is harmful to both general and oral health. 2,5 This study revealed that Tharu people also had the habit of consuming sugar-containing items like sweet and candy, milk with sugar, and tea/coffee with sugar. More than 4 in 10 Tharu participants eat sweets and candy several times a month followed by once a week (17%), several times a week (10.1%), several times a day (1.9 %), once a day (1.3%), and 27.7 % participants never had the habit of consuming sugar-containing items like sweets and candy. About half (46.5%) of the participants had no habit of drinking milk with sugar. Participants who drank milk with sugar once a day were 17.6 %, followed by several times a week (13.2%), several times a month (13.2%), once a week (8.2%), and very few (1.3%) had the habit of drinking milk with sugar several times a day. More than one-third (35%) of the participants drank tea with sugar once a day followed by several times a day (26.4%), several times a week (10.7%), several times a month (6.3%), once a week (3.1%), whereas 18.2 % of the participants had no habit of taking tea with sugar. Substantial numbers of people were there who had never taken jams, sweets, candy, and chewing gums. Tea and coffee drinking habits were also less among Tharu people i.e. only 1.3 % had the habit of taking coffee several times a month. Our study suggested that oral hygiene practices are satisfactory among the Tharu community. Tobacco use and food habit that affects oral health was also prevalent among them. Thus, community-based oral health promotion would be beneficial to sustain oral hygiene practices, reduce use of tobacco and food habit that affects oral health. 1Study on Oral Hygiene Practices, Tobacco use, and Food Habits among Tharu Community ofGadi Rural Municipality, Nepalmunicipality, Sunsari, Nepal, from February to August2015. Participants aged ?18 years of either gender orwillingness to participate in the study were included inthe study. A sample size of 159 was taken to exploreoral hygiene practices, tobacco use, and food habitsamong the people of Tharu community using apurposive sampling method. Since the sampling framewas unknown, the recent population census of 2011(34852) provided by the Gadi Rural Municipality wasused to determine the required sample from each ward.A face-to-face interview was conducted to collect data.The data collection sheet consisted of questions ondemography (age, gender, education, marital status,occupation, type of family, and number of familymembers). The oral hygiene practice was assessedusing seven questions that covered brushing habits,dentifrices used, time of brushing, methods of brushingteeth, use of toothpick, and changing brush interval.VariablesFrequencyPercentage (%)Age18-358553.4536-554226.41?563421,38GenderMale6742.1Female9257.9Marital StatusMarried13383.6Unmarried1911.9Widow74.4EducationNever went3320.8Informal2415.1Primary1811.3Secondary6842.8Certificate level138.2Bachelor level and above31.9OccupationUnemployed11169.81Non-government employee1911.9Self-employed148.8Student138.2Government employee21.3 2Types of FamilyJoint7647.8Nuclear8352.2Family Member1-462395-88150.9? 91610.1VariablesFrequency Percentage (%)Brush their teethYes159100Dentifrices usedFluoridated11579.9Non fluoridated149.7Can't say1510.4Time of brushing teethMorning13484.3Bedtime2012.6Morning +bedtime31.9Anytime21.3Use of toothpicksYes14373.0No2727.0Frequency of Brushing /dayLess than Once53.144Once13081.76Twice2415Method of brushing teethBrush and toothpaste13886.8Brush and tooth powder63.8Karchi53.1Datiwan106.3 3Types of tobaccoFrequencyPercentage (%)Cigarette smoking1-5 sticks/day1429.76-10 sticks/day510.611 and more sticks/ day24.2Tobacco leaf1 packet/day1838.3More than one packet/day48.5Chilim/Hookah20 times/day24.2Gootka1-6 packet/day24.2 4aVariableFrequencyPercentage (%)Fresh FruitSeveral time a day95.7One time a day95.7Several times a week95.7Once a week2918.2Several times a month8150.9Never21.3 4bJunk foods One time a day Several times a week Once a week Several times a month Never26 33 32 51 104 16. 8 20. 1 20. 32. 1 10.1Soft DrinksSeveral times a week Once a week Several times a month19 17 8711. 9 10. 7 54. 7Never3421.4Jam/HoneySeveral times a month Never15 14410 90VariablesFrequencyPercentage (%)Sweets/candySeveral times a day31.9One time a day21.3Several times a week1610.1Once a week2717.0Several times a month6742.1Never4427.7Milk with sugarSeveral times a day21.3One time a day2817.6Several times a week2113.2Once a week138.2Several times a month2113.2Never7446.5Tea with sugarSeveral times a day4226.4One time a day5635Several times a week1710.7Once a week53.1Several times a month106.3Never2918.2Coffee with sugarSeveral times a month21.3Never15798.7IV.Discussion and its relation to sociodemographic factors amongpatientsattendingthegeneraloutpatientdepartment in a tertiary care hospital of Kolkata,India.
