Mo8va8ng tobacco users through behavioral counseling is the mainstay for achieving tobacco abs8nence. Research evidence suggests a larger role of dental professionals in mo8va8ng tobacco users to quit. The efforts of private dental prac88oners in providing Tobacco Cessa8on Interven8ons (TCI) in their clinics need to be measured and acknowledged. Methods: A cross-sec8onal survey based on self-administered ques8onnaire with private dental prac88oners was carried out in the state of Delhi, India. The main objec8ves of the survey were to assess the current prac8ces and the barriers experienced in providing TCI by the par8cipa8ng den8sts. Sta8s8cal analysis was conducted to find out the associa8on between independent variables and the responses to ques8ons on tobacco cessa8on. Results: The mean age and years of prac8ce of 297 par8cipa8ng den8sts was 37.2 (SD 9.8) and 11.9 (SD 9.5) years respec- 8vely. Most of them were graduate (N=204, 68.7%). Only 17.2% (N=51) of the par8cipa8ng den8sts had undergone any training in providing TCI. Most of the den8sts felt that the lack of proper training (N=146, 49.2%) and resistance by pa8ents (N=185, 62.5%) are the main barriers in providing TCI. Younger den8sts (<35 years) performed significantly be[er than older den8sts in many parameters pertaining to a\tude and prac8ces of TCI in their clinics. Conclusion: This is a pioneer survey conducted on the issue of TCI provided by private dental prac88oners of Delhi. The study results show that around 2/3rds of the par8cipa8ng private dental prac88oners were providing TCI to their pa8ents but there are certain barriers for its proper implementa8on. Therefore, there is an urgent need to remove these self- reported barriers and build self-confidence among the den8sts for ins8tu8ng effec8ve TCI in their clinics.

Email: amehta@jmi.ac.in Introduction Consuming tobacco increases the risk of several oral and general health problems such as cancer of oral, lung and pharyngeal region, cardiovascular problems and perio- dontal diseases [1]. It is estimated that by the year 2030, tobacco will be the leading cause of mortality in human population worldwide [2]. India is home to the second highest tobacco consumers in the world, with 267 million active tobacco us- ers and more than one million to- bacco related deaths occurring each year [3]. These numbers sug- gest we are in the second stage of tobacco epidemic [4]. A person can quit the habit of to- bacco consumption with self-moti- vation and professional help. Tobacco cessation programmes are gaining acceptance worldwide as they are found to be an effective preventive measure [5,6]. Tobacco cessation interventions (TCI) pro- vided by physicians and dental care professionals have shown improve- ment in tobacco abstinence rates [7,8]. In spite of the strong evi- dence, it was observed in the sec- ond Global Adult Tobacco Survey Tobacco use cessa*on efforts among private dental prac**oners of Delhi Vol 8 No 1 (2020) DOI 10.5195/d3000.2020.99 http://dentistry3000.pitt.edu (GATS-2) India, only 54.5% smokers were asked regarding their tobacco use status and 48.8% were advised to quit tobacco by a Health Care Professional (HCP) [9]. There is an urgent need to provide accessible and universally available tobacco cessation services for Indian popu- lation. Dental professionals are role mod- els and leaders who can affect the attitude of people in a community. Dentists are usually the first person to become aware of an individual’s tobacco habit during the course of routine dental check-up. Dental clinic is an excellent venue for providing TCI to the visiting pa- tients. Dentists can show visible ev- idence of the ill effects of tobacco on the oral cavity to their patients, which can motivate them to quit tobacco. Smoking cessation pro- gram run by the dentists in USA and UK had achieved quit rates of 10-20% [6,7]. In spite of these facts, most of the dentists don’t provide TCI services to their pa- tients. Even in developed countries like USA and Canada, half of the dentists don’t advise their patient to quit tobacco [2,10]. There are several reasons reported for this finding such as lack of time, reim- bursement or training and re- sistance by patient [10]. India has 274154 registered den- tists [11] and a dentist population ratio of 1:10,571 [12]. This large health care workforce can be trained and utilized to provide TCI to individual patients and commu- nity. Most of the dentists in India are involved in private practice of their own or as an employee. Very few dentists are working in govern- ment or private dental colleges. Therefore, if these private dental practitioners are able to provide ef- fective TCI to their patients it can have an enormous public health impact. Efforts are being made at government and dental associa- tions’ level to increase the role of dental professionals in the fight against the tobacco epidemic in our country [13,14,15]. As per our knowledge only three studies [16,17,18] have been conducted to assess the tobacco cessation ef- forts of private dental practitioners in India and no study is reported from Delhi which is capital of India. Therefore, a cross-sectional study was planned with the following ob- jectives: 1. To assess the level of TCI provided by private dental prac^^oners in Delhi state. 2. To find out the barriers in- curred in providing these interven^ons. Methods Study sample The sampling frame for this study was all the dentists working in a private dental clinic in Delhi state. As per available records from Den- tal Council of India, there are 14366 registered dentists in Delhi [11]. List of dentists with their phone number or email ID was available from local IDA branch. Sample size for this survey was cal- culated using Epinfo software. Required sample size was 316 (at 95% confidence level and 5% error margin), if we considered 70% of the dentists in Delhi are practicing TCI in their clinics. We contacted 330 dentists for participating in this study but only 297 dentists agreed for the same. Participating dentists were recruited using multiple methods e.g. personal visit, tele- phonically, by visiting conferences or continuing dental education programs organized by state dental associations, and through email. Every effort was made to give equal representation to both the genders as well as dentists practic- ing in urban or rural areas. Eligibility criteria Dentist practicing in a dental clinic in Delhi and willing to participate in the study. Ethical clearance An approval was obtained from in- stitutional ethical committee be- fore commencement of data col- lection (letter no. PDM/IEC/01/2019). Assessment tool A structured, self –administered questionnaire was prepared to rec- ord necessary information. The questionnaire was divided into five domains, starting with recording baseline information of the partici- pating dentists, assessing their atti- tude towards TCI, practice of 5As (Ask-Advice-Assess-Assist-Arrange) approach in their clinic, different strategies utilized to motivate their patients to quit tobacco and finally, Tobacco use cessa*on efforts among private dental prac**oners of Delhi Vol 8 No 1 (2020) DOI 10.5195/d3000.2020.99 http://dentistry3000.pitt.edu self-reported roadblocks/barriers in providing these TCI. The face and content validity of the questionnaire was evaluated by sending it to five experts working in the field of tobacco cessation. These experts were asked to rate each question in order to assess its suitability for this study. Based on the feedback received from the ex- perts necessary changes were made in the questionnaire. This questionnaire was then pilot tested on 20 private dental practi- tioners and their responses and suggestions were recorded. After these steps, the questionnaire was finalized for the main survey. Relia- bility of the questionnaire was as- sessed using Cronbach alpha test (alpha = 0.8) by repeating it to ten previous study participants. Data collection The data were collected by single investigator (RP). Randomly se- lected dentists were recruited us- ing multiple methods by the inves- tigator e.g. telephonically, by visit- ing conferences or continuing den- tal education programs organized by state dental associations, and through email. The dentists were explained the study objectives and were asked to provide signed in- formed consent for participation in the study. In order to achieve a higher response rate, and wher- ever possible, the investigator per- sonally visited the clinic of the par- ticipating dentists on a mutually consented time and date. The filled form were collected on the same day (preferably) or within 2 days of submission. Those dentists who agreed to fill an online form were sent a prepared Google form of the questionnaire. After receiving the filled form, the investigator checked the form to make sure all the questions are answered by the participating dentist(s). Data col- lection was completed within two months (June and July 2019). Statistical analysis The data was analyzed using Statis- tical Package for the Social Sciences Version 21.0 (IBM Corp., Armonk, NY, USA). Frequency distribution tables were prepared to present overall and subgroups data. Chi- square test was used to analyze the statistical differences between di- chotomous independent variables such as number of years of prac- tice, age and gender of the partici- pating dentist with regards to re- sponses to various sections of questionnaire (dependent varia- bles). Probability value (P)< 0.05 was considered as statistically sig- nificant. Results Baseline characteristics of the study population We contacted 330 dentists to par- ticipate in this study, of which, 297 (155 males and 142 females) re- sponded and gave their consent. Therefore, the response rate was 90%. Baseline characteristics of study participants showed that slightly more than half (51.2%) of the participating dentists were in age bracket of 35 years or above, and were into private practice from last 8 years or more (N=153, 51.5%). Around two-thirds of them (N=204, 68.7%) were graduate and only few had done post-graduation (n=93, 31.3%). As the numbers of dentists with graduate degree were far more than those with post-graduation, it was decided that no further comparison for out- come variables will be done be- tween these two groups (table 1). Table 1. Baseline characterisDcs of parDcipat- ing denDsts. Attitude of participating dentists towards tobacco cessation Most of the participating dentists were aware of the fact that TCI can be provided in a dental clinic (N=265, 89.2%) and 87.5% thought TCI in dental clinic can be effective. Thirty six percent of the participat- ing dentists (N=107) felt their pa- tients expect them to provide TCI but only 51 (17.2%) had undergone any formal training to learn these services or interventions. Majority of dentists were educating their patients regarding ill effects of to- bacco on general and oral health (n=293, 98.7%). Bivariate analysis using chi-square test showed that a significantly Tobacco use cessa*on efforts among private dental prac**oners of Delhi Vol 8 No 1 (2020) DOI 10.5195/d3000.2020.99 http://dentistry3000.pitt.edu higher awareness towards provid- ing TCI in dental office was seen in dentists in older age group (>35 years) and among females. Signifi- cantly more dentists in older age group, those with more years of practice (>9 years) and females practitioners believed that their patients expect them to provide TCI in their clinic (p<0.05). On the question of effectiveness of TCI in dental office, significantly more fe- male dentists felt that such inter- ventions are an effective tobacco control measure when compared to male dentists (p<0.05) (table2). Practicing 5As approach Two-thirds (n=196, 66%) of the participating dentists were asking most of their patients (more than 75%) about their tobacco use sta- tus; rest 34% (N=101) were asking from less than 75% of their total patients. Almost all of the partici- pating dentists (n=290, 98.6%) were advising their patients (who were consuming tobacco) to quit the habit and more than 3/4th (n=226,76.1%) were assessing their patients’ intention to quit as well as assisting them in quitting to- bacco (n=235, 79.1%). Less than one-third of the participating den- tists were helping their patients in setting a quit tobacco date (n= 88, 29.6%) and even lesser number were arranging for a follow-up ap- pointment after the quit date (n= 45, 15.2%).

Signifi- cantly more dentists in the older age group and those who had more than eight years of practice were asking most of their patients (>75%) regarding their tobacco use addiction. Dentist of older group (>36 years) and female dentists were assessing their patients’ in- tention to quit tobacco in signifi- cantly higher frequency when com- pared to dentists of younger age (<35 years) and males respectively (p<0.05). There was no difference in any of these dichotomous groups about arranging follow up appointment after quit date (table 3). Strategies for helping patients to quit tobacco Prescribing Nicotine Replacement therapy (NRT) was the most com- mon strategy of the participating dentists in helping their patients achieve tobacco abstinence (n=153, 51.5%). Providing self-help educational material (n=122, 41.1%) was second most common strategy followed by referring the patient to a tobacco cessation cen- tre (n=72, 24.2%). Very few den- tists were prescribing drugs such as Bupropion or Varnecline (n=19) or providing tobacco quit line number Table 3.

Younger dentists reported to have provided educa- tional materials to their patients in significantly higher frequency than older dentists (table 4). There was no significant difference in gender, age and years of practice groups re- garding implementation of any other tobacco cessation strategies. Self-reported barrier to providing TCI to a dental patient Resistance by patient to receive TCI was the biggest barrier re- ported by the participating den- tists (n=185). Female dentists and those who had practiced dentistry for more than eight years reported this as a barrier significantly more than compared to male dentists and dentists with less than eight years of practice respectively. Lack of proper training in providing to- bacco cessation and amount of time consumed were the other common barriers reported by the participating dentists. Significantly more dentists of older age and more years of practice felt lack of training as a barrier as compared to their comparative groups. Lack of time to provide TCI to their pa- tients was significantly a more im- portant barrier for the male den- tists and dentists with less than eight years of practice. Less than fifty dentists perceived lack of re- imbursement, non-familiarity with the available referral options and fear of losing patients as a barrier to TCI in dental clinic. No signifi- cant difference was observed be- tween the different groups for these three barriers (table 5). Discussion The purpose of the present study was to evaluate the knowledge, at- titude and practices of private den- tal practitioners of Delhi in imple- menting TCI in their dental office. Self-reported barriers encountered during these interventions were also recorded. The results of the study show most of the participat- ing dentists believed in the effec- tiveness of TCI in dental office and many of them were implementing four (Ask-Advice-Assess-Assist) out of five tasks (except “Arrange”) of 5As approach recommended for tobacco cessation. The major lacu- nae (identified through this study) Table 4. Strategies uDlized by the parDcipaDng denDsts for helping their paDents to quit tobacco. *sta-s-cally significant difference p<0.05, chi square test Tobacco use cessa*on efforts among private dental prac**oners of Delhi Vol 8 No 1 (2020) DOI 10.5195/d3000.2020.99 http://dentistry3000.pitt.edu hindering the proper implementa- tion of TCI by the participating den- tists were lack of formal training, most of the dentists didn’t think that patients expect them to pro- vide TCI, and there was lack of proper follow- up mechanism of to- bacco users in the dental office. Tobacco treatment guidelines de- veloped by Government of India [4] had suggested strategies for to- bacco cessation in the form of 5As (if person is willing to quit tobacco) or 5Rs approach (if person is not willing to quit tobacco) [7]. These guidelines are research-based and accepted globally [19]. A typical TCI involves counseling session of ap- proximately 5-8 minutes to each tobacco user using 5As approach. If this is not possible (due to lack of time) a brief intervention session (approx. 2-3 minutes) that requires Health Care Professionals (HCP) to Ask every patient regarding their tobacco status, Advise them on quitting tobacco and Assess their willingness to quit (3As) [2,20]. In our study, only 66% participating dentists were asking the majority of (more than 75%) their patients about tobacco consumption status. These numbers are quiet similar to those reported among dentists of Saudi Arabia and Kuwait [21], United Kingdom [22], Iran [23] and Netherlands [24] but higher than that reported in Canada [10] and Udaipur, India [25] and lesser than that reported in Pakistan [26], Modinagar, India [16], Nigeria [27], Yemen [28] and United states of America [29]. Asking about tobacco consumption status is the foremost step a HCP must perform towards identifying patients who are ad- dicted to tobacco. Hence there is need to improve the awareness of all HCP to ask each and every pa- tient regarding their tobacco his- tory. In our study, most (97.6%) of the participating dentists were ad- vising tobacco users to quit. This percentage was much higher than that reported by similar studies around the world [10,16,21,23,25,26,27,29]. It is an encouraging finding since research had shown even a brief advice by HCP could motivate patient to quit or at least reduce tobacco con- sumption [30]. Around 3/4th of the study participants (76.1%) were Table 5. Barriers perceived by parDcipaDng denDsts in providing TCI to their paDents. *sta-s-cally significant difference p<0.05, **p<0.001, chi square test Tobacco use cessa*on efforts among private dental prac**oners of Delhi Vol 8 No 1 (2020) DOI 10.5195/d3000.2020.99 http://dentistry3000.pitt.edu assessing their patients’ intention to quit tobacco. These figures are much higher than that reported by similar studies [10,23,25,27]. As per GATS-2 India less than 15% of tobacco users were planning to quit in next one year and even less than 10% in next one month [9]. These figures are suggestive of fail- ure on part of health care services to motivate tobacco users to quit the habit. Obtaining information on patient’ intention to quit helps dental professionals to evaluate to- bacco user motivation to quit to- bacco. Along with setting a quit date, intention to quit has been found to be associated with higher tobacco abstinence rates [20]. Assisting the tobacco users in quit- ting the habit requires time and commitment from health care pro- fessionals. In present study, more than 3/4th (79.1%,n=235) of the participating dentists had reported to assist their patients in achieving tobacco abstinence. However, when specifically asked about the strategies for assistance, less than 30% of the participating dentists were helping their patients to set a quit date and even fewer (15.2%) stated that they were arranging a follow-up appointment for tobacco users. These numbers are much less than that is reported by studies done in Canada [10], US [29] and Nigeria [27] but higher than studies done in Pakistan [26], Iran [23] and Udaipur, India [31]. These observa- tions reflect a lack of long term commitment of participating den- tists to make sure their patients are free of tobacco addiction. It is a widely known fact that tobacco us- ers require multiple attempts be- fore they finally quit [32]. There- fore, if a health care professional is not providing an option of future follow up it will ultimately lead to poor abstinence rate among its pa- tients. Follow-up appointments are also extremely important for den- tists to reinforce their health edu- cation message and for patients for sharing problems they are facing during the process of tobacco ab- stinence. Patients must be re- minded repeatedly regarding im- mediate and long-term benefits of quitting tobacco [33]. Most common strategies utilized by participating dentists to help their patients quit tobacco were prescribing NRT, providing self-ed- ucation material and referring to a tobacco cessation centre. Fre- quency of self-reported prescrip- tion of NRT to their patients was much higher in our study sample compared to similar studies [10,16,22,26,29]. Prescribing NRT is an effective method of replacing nicotine obtained from direct to- bacco products and has shown to increase the chances of tobacco abstinence rate up to 50-70% [34]. In our study, we tried to find out the barriers impeding implementa- tion of TCI by the participating den- tists. “Resistance by patients” was the most common barrier reported by the dentists. Studies done among dentists of European Union [35] and Canada [10] had found this factor as one of the main bar- rier. “Lack of adequate training” in providing TCI was another im- portant barrier reported. Dentists without proper knowledge and training will lack confidence in con- ducting TCI in their office and hence would not be able to moti- vate their patient to quit tobacco. Similar results were observed by studies conducted in different parts of the world [10,16,27]. “Lack of time” to provide TCI was the third most common barrier re- ported by the dentists in our study. Many studies had reported this as one of the most common barrier [10,18,21,22,25,27]. Dental treat- ment is inherently laborious and requires more time for a single pa- tient or procedure when compared to a general physician. The dentists must be educated and motivated towards the rewards and responsi- bilities of providing TCI. In the pre- sent study, Lack of monetary bene- fit from TCI was considered as a barrier by only 42 (14.1%) dentists. This figure is quiet lower when compared to other studies around the world [10,22,27] and India [18,19] except for one Indian study [16]. TCI in dental office is usually not a reimbursable service. Alt- hough efforts should be directed to include it as a chargeable service but more importantly dentists must be educated that tobacco cessation activities can help them build a reputation with their pa- tients and neighborhood commu- nity. Bivariate comparative analysis of the study participants shows younger dentists (<35 years of age) had better awareness and self- Tobacco use cessa*on efforts among private dental prac**oners of Delhi Vol 8 No 1 (2020) DOI 10.5195/d3000.2020.99 http://dentistry3000.pitt.edu belief regarding provision of TCI in their clinic. Dentist of younger age group performed significantly bet- ter in implementing Ask, Advice and Assist tasks of 5As approach to their patients. They were providing self-help education materials in higher frequency as compared to dentists above 35 years of age. Fi- nally, the younger dentists didn’t perceive lack of training as a barrier in providing TCI when compared to older dentists. Possible explana- tion for such observations could be better awareness of younger gen- eration of dentists regarding im- portance of providing TCI to their patients. It could be due to changes in dental school’s curriculum with compulsory lectures as well as hands on training for dental stu- dents on tobacco cessation [36]. Establishment of tobacco cessation centre is now mandatory for all dental colleges in India [13]. This initiative will increase practical knowledge and confidence of grad- uates in providing TCI to their pa- tients once they come out of dental college and open there clinic. There has been better availability of training in form of continuing education and workshops on to- bacco cessation which helps pri- vate practitioners to update their knowledge on tobacco cessation. Limitations and strengths The present study is not without limitations and therefore its re- sults should be interpreted keep- ing them in mind. This study is lim- ited to private dentists practicing in Delhi state. Therefore, these re- sults are not representative of dental professionals of the whole country. Second, the findings of the study are based on self-re- ported answers where individuals might report good knowledge of a particular topic without undergo- ing assessment on its practical im- plementation part. For example, most dentists are aware and un- derstand the importance of to- bacco cessation but whether they are actually implementing it in their dental office cannot be as- sessed with a questionnaire study. Such self –reporting studies are also prone to recall bias. Third, is the issue of selection bias in the study sample, as dentists inter- ested and motivated towards TCI may get enrolled for this study. We feel chances of selection bias is less in our sample as refusal rate (not to participate in the study) is just ten percent and every at- tempt was made to recruit den- tists regardless of their past expe- rience in providing TCI. Fourth, as this study is cross sectional in de- sign therefore it’s not suitable to draw any causal relationships. Fi- nally, we didn’t assess participat- ing dentists own habit of tobacco use. It has been reported that den- tists who smoke tobacco are less keen on engaging their patients for TCI [21,28]. Conclusions The results of our study present an overview of the current scenario of tobacco cessation efforts made by private dental practitioners of Delhi and barriers experienced by them. Efforts should be made to eliminate these barriers and increase the practical knowledge of dentists on providing TCI to their patients. Efficient and skill-based training provided through changes in dental curriculum, conducting workshops and online courses could help in increasing tobacco abstinence among Indian popula- tion.
