Abstract

Objective: To determine the frequency of oral submucous fibrosis in patients coming to dental OPD of a tertiary care hospital and to correlate the association of level of education among patients of oral submucous fibrosis.
Methodology: A cross sectional study was conducted from January 2018 to December 2018 among patients coming to the dental OPD of a tertiary care hospital in Karachi. Convenience sampling was used to select patients of Oral Submucous Fibrosis and a structured questionnaire was used to collect data on level of education, age, gender and Habit.
Result: A total of 4405 patients visited the OPD and 135 patients were diagnosed with OSMF based on clinical findings. Mean age of OSMF patients was 33.6 years with nearly half 47.7% having no formal education.43.2% were skilled workers followed by 34.8% housewives and 22% were professionals. Betel nut was the most common used habit 79.5% among OSMF patients. Significant association of betelnut (p-0.001) among females(94.5%) compared to males (68.8%) and significant association of gutka (p-0.004) among males(24.7%) than females (5.5%)was observed. No significant association of level of education with substance abuse was observed.
Conclusion: The finding of high frequency of betel nut usage among housewives and gutka among skilled workers is alarm some. Our literacy level despite being very low is not the sole reason of increase of substance abuse rather even the educated ones are not at par with this habit.

Introduction

Oral submucous fibrosis is recognized by WHO as a precancerous lesion, which has a high rate of conversion into oral squamous cell carcinoma. The oral epithelium becomes atrophic and is injured easily along with fibrosis occurring in the tissue which limits the mouth opening. Problem gets much worst when the limitation increases to the level of inability of chewing and swallowing due to the fibrosis of the soft palate [1].

The disease is more prevalent in South East Asia whereas only few cases have been reported in the United States and European countries and those too are a result of the migratory Asians. Countries with the highest burden of disease are India, Taiwan, Srilanka and Pakistan. Studies done in India (Ahmadabad, Gujarat and other cities) have clear data on the increase in the incidence of oral cancer in the past 2 decades attributed to increase in the OSF cases. Largest increase of >30 times in the incidence of mouth cancer has been reported from 1985 to 2010 [2].

Studies indicated that men are most commonly affected between the ages of 25-35 in both rural and urban population [2].

Studies conducted in various parts of South East Asia have established betel nut (areca nut) as the major risk factor of OSF. Betel nut (areca nut) chewing directly or in the form of pan, gutka or mawa has been reported to cause OSF. (100% among OSF cases in Taiwan) [3]. The International Agency for Research on cancer of the WHO evaluated areca nut as a carcinogenic substance [4]. OSF is related to both its frequency of usage and duration that it’s kept in the mouth. A survey was conducted in different socioeconomic areas to assess the knowledge of people regarding the adverse effects of betel nut which concluded that despite having knowledge about oral cancer people were reluctant to give away the habit. [5]. The billion dollar market of gutka with easy access and reduced price and the increasing incidence of OSF, constitutes a major public health risk with young being the most vulnerable [2]. However there has been no research to find out if the level of education can reduce the habit of substance abuse, resulting in reduction of Oral Submucous Fibrosis. The objective of the study is to determine the frequency of Oral Submucous Fibrosis in patients coming to dental OPD of Sindh Institute of Oral Health Sciences from January 2018 to December 2018 and to compare the level of education among patients of oral submucous Fibrosis.

Materials and Methods

A cross sectional study was conducted from January 2018 to December 2018 in patients coming to the dental OPD of Sindh Institute of Oral Health Sciences. Convenience sampling was used to select cases of oral Submucous Fibrosis. Inclusion criteria was all subjects diagnosed on basis of presence of fibrous bands causing decreased mouth opening (<30mm) were included in the study. Fibrous bands were palpated through clinical examination and mouth opening measured with vernier caliper. For the collection of data, a structured questionnaire containing details of socio-demographic, habit characteristics and level of education was used.

SPSS 20 was used for data analysis. Qualitative variables were summarized as percentages and quantitative variables as mean and standard deviation. Chi- square test was used to determine the relation between independent factors (age, gender, occupation and Habit (form, frequency and duration) with dependent factor i.e. level of education among oral submucous Fibrosis patients. P-value of < 0.05 was considered significant. Ethical approval was taken from the institutional review board and informed consent was obtained from all participants. Data was collected by trained data collectors and supervised by the principal Investigator.

Results

A total of 4405 patients visited the dental OPD from January 2018 to December 2018. Around 135 cases of oral submucous Fibrosis were identified out of 4405 based on clinical presentation of Fibrous bands and limited mouth opening. 2% of the participants did not consent to participate in the study which left the sample to be 132 cases of OSMF.

More than half of the patients with oral submucous fibrosis were males 58.3% (77) followed by 41.7% (55) females. The mean age of the patients was 33.64 (SD 12.58). Nearly half of the patients had no formal education 47.7% (63) and only one third had primary and matric 27.3% (36) and intermediate and above 25% (33). Nearly half of the patients were skilled workers (laborers, carpenters, street wanders and construction workers) 43.2% (57) followed by 34.8% (46) housewives and 22% (29) professionals (doctors, nurses, businessman, and engineers) (Table 1).

As shown in (Figure 1) more than three –forth (3/4) 79.5% of the patients ate Betel nut (betel nut), while 22% ate Pan, 16.7% Gutka and 6.8% did smoking.

Figure 1: Frequency of Different Substance Abuse among Oral Submucous Fibrosis Patients (n=132).

The average daily consumption of Betel nut in patients of oral submucous Fibrosis was 6.10 (SD 3.9) packets and the average mean duration of use is 9.09 (SD 5.3) years. The average daily consumption of Pan is 5.5 (Standard deviation of (SD) 5.2) and average years consumed is 10.41 (SD 5.6) in patients of oral submucous fibrosis. The mean daily consumption of Gutka is 3.41 (SD 2.1) and average years consumed is 9.09 (SD 6.3). Whereas the average cigarettes smoked is 9 (SD 7.3) per day in patients of oral submucous fibrosis and the average years consumed is 11.78 (SD 3.4) (Table-2).

Also a significant association (p-value 0.004) was observed in the frequency of Gutka consumption with Males (24.7%) consuming higher frequency than females (5.5%). The association of Gender with smoking was also significant (p-value 0.010) with males (11.7%) as compared to females (1%). The level of Education had no significant association with any of the substance abuse. Occupation was significantly associated (p-value 0.001) with frequency of Betel nut in housewives (93.5%) as compared to Skilled (63.2%) and Professionals (89.7%). Occupation was also significantly associated (p-value 0.002) with gutka more consumed among Skilled (29.8%) as compared to housewives (6.5%) and (6.9%) in professionals. Skilled workers (14%) also showed more frequency in smoking as compared to housewives (1%) and professionals (3.4%) and the association was significant (p-value 0.014).

Discussion

The frequency of Oral Submucous Fibrosis was found to be 3% in patients coming to dental OPD within one year. The frequency is higher than was observed in Dhanbad district of Jharkand, India which was found to be 1% in 2018 [6]. But is consistent with findings from Hunain Province, China 1%-3% [7]. Majority of the patients were males with an average age of 33 years, which is consistent with studies from the Asian sub-continent and also a previous study conducted in Pakistan by Sidra Mohiuddin [6-8]

We found that majority of the patients of OSMF consume betel nut 79.5% on daily basis with an average consumption of 6 packets daily for nine years. This is consistent with the study from Taiwan and India which clearly states the use of betel nut as a major etiological factor for OSMF [2-3]. However a large number of Gutka consumers 16.7% (also a product of betel quid and slime) are associated with increased of OSMF and the second major habit found in our study is the use of Gutka among OSMF patients [9]. According the Pakistan Medical association’s statistics 1.5 million oral cancers occur due to the use of betel quid and gutka [13].

The use of betel nut was significantly higher in females as compared to males in our study and this finding is in contrast to previous studies conducted in Pakistan and India [1-10] which shows a high frequency among men, however our results are in line with study in Cambodia and Pacific island of Palau where women are predominant users of Betel nut [11-12]. Also the rare use of female smoking observed in our study is consistent with Cambodia [14], where a significantly low usage is observed among females than males. However the use of gutka is more among males which is also in line with previous studies [9-13].

We found that the Habits of betel nut, gutka, pan and smoking were more among those who had no formal education which is in contrast to study in India where high frequency was observed among Secondary and college students followed by illiterate [14]. However the use of gutka among skilled workers is in line with studies from India which also highlights the use of gutka and betel nut among laborers, tea sellers, wage earners and other skilled workers as compared to professionals like engineers, managers and other formally employed workers [14]. A major reason is the need of alertness and reduced hunger which these products are known to provide along with their soothing effects, which is a major compromise in low-income countries substituting low cost substance abuse with healthy diet [14]. However the high usage of betel nut among housewives is very much related to the familial background of consumption as highlighted in previous literature [9-14].

No association of habit with education clearly states that there is a need of awareness campaigns at school and college levels which would reduce the menace among the educated class. Also we recommend provision of low cost healthy food to the skilled and daily earners, so they won’t have to kill their hunger in order to survive and rely on such substances of abuse. Moreover strict action of government is required in the commercial ban of the product with regular monitoring and follow-up.

We had limitations and the study was only a single government hospital, therefore the results cannot be generalized on the entire population of Karachi.

In conclusion, the study is only a snap shot of the current patients of OSMF coming to dental OPD of a tertiary care hospital. The finding of high frequency of betel nut usage among housewives and gutka among skilled workers is alarm some. Our literacy level despite being very low is not the sole reason of increase of substance abuse rather even the educated ones are not at par with this habit.
