| Introduction|| |
Oral ulceration is one of the most common diseases affecting the human population. Ulcerations are characterized by a defect in the epithelium and underlying connective tissue measuring approx. 2–5 mm in diameter usually resolves in 10–15 days but generally reoccurs. Ulcers can be acute or chronic/recurrent, solitary or multiple. Recurrent aphthous stomatitis represents the most common form of oral mucosal ulceration encountered in healthy individuals lacking any association with systemic disease., The term aphthae is derived from the Greek word aphthae which means “to set on fire” or “to inflame” and is thought to be first used by philosopher Hippocrates to describe the pain associated with a common disorder of the mouth during his time. The lesion starts in childhood or adolescence as recurrent small, round, or ovoid ulcers with circumscribed margins, erythematous halo, and yellow or gray floor., These ulcers occur periodically and heal completely between attacks. In the majority of cases, it lasts about 7–10 days for 3–6 times per year.
Recurrent aphthous ulcers are clinically present in three different forms: minor, major, and herpetiform.
- The minor form is the most common type representing 70%–85% of all recurrent aphthous ulcers. It presents as a small (up to 1 cm in diameter) shallow, painful ulceration which heals without scarring after 10–14 days
- Major form accounts for 7%–20% of all cases, has more than 1 cm in diameter, is deeper, and can last for months, leaving a scar
- The herpetiform form represents just 5%–10% of all cases. They are in the form of pinpoint ulcers (0.1 cm to 0.2 cm) occurring in large numbers (5–100 ulcers at a time) which sometimes coalesce to form a large and irregular lesion having a clinical course of 7–10 days.
The etiology and pathogenesis of recurrent aphthous ulcers remain unclear. Multiple factors associated with the establishment of the disease include positive family history, food hypersensitivity, smoking cessation, psychological stress, and immune disturbance., Recurrent aphthous ulcer is a common mucosal disease, but very few studies have been done to find its prevalence in India. The objective of this study was to find the prevalence of recurrent aphthous ulcers and their distribution according to gender and site in different age groups.
| Materials and Methods|| |
The study was carried out among the patients reporting to the Outpatient Department of Dentistry, Government Medical College, Badaun, from September 2019 to March 2020. Diagnosis of recurrent aphthous ulcer was made based on patient history and clinical examination. Parameters recorded were age, gender, and site affected. The patients were divided into eight age groups (10 years of each interval). Various sites recorded were tongue, lower lip, upper lip, buccal mucosa, soft palate, and floor of the mouth. The data were collected and analyzed using SPSS software version 22.0 (IBM, Armonk, New York, USA).
Discrete (categorical) data were summarized in number (n) and percentage (%) and compared by Chi-square (χ2) test. A two-tailed (α = 2) P < 0.05 was considered statistically significant. Analysis was performed on SPSS software (Windows version 22.0).
| Results|| |
A total of 7400 patients who reported to the outpatient department were screened, of which 291 were diagnosed to be affected with the recurrent aphthous ulcer, giving the overall prevalence of the disease to be 3.9% [Table 1]. Among 291 recurrent aphthous ulcer patients, 143 (49.1%) were male and 148 (50.9%) were female [Figure 1]. The prevalence of recurrent aphthous ulcers was 1.8% higher in females than males. The age of recurrent aphthous ulcer patients ranged from 1 to 80 years with a mean age of 25.10 years. The prevalence of recurrent aphthous ulcers was higher in lower age groups (11–40), accounting for 239, which was 82.1% of the total recurrent aphthous ulcer [Figure 2]. Interestingly, the prevalence of recurrent aphthous ulcers was found to decrease with an increase in age.

The prevalence of recurrent aphthous ulcers according to sites was 320, as 11 patients reported 29 more recurrent aphthous ulcers at multiple sites. According to the site, the prevalence of recurrent aphthous ulcer was maximum in the tongue (45.3%) followed by lower lip (34.1%), accounting together 79.4% of the total recurrent aphthous ulcer at different sites [Table 2] and [Figure 3]. The prevalence of it was found minimum on the floor of the mouth (0.9%). The site-wise prevalence of recurrent aphthous ulcers in different age groups is summarized in [Table 2] and also depicted in [Figure 3]. According to age, the maximum cases affecting tongue were seen in the second decade of life (37.9%), followed by the fourth (21.4%) and third (20.7%) decades of life. The second most affected was lower lip, again highest in the second decade of life (35.8%), followed by third (26.6%) and fourth (22.0%) decades of life. However, the Chi-square test showed an insignificant (P > 0.05) difference in the prevalence of recurrent aphthous ulcer between age and sites (χ2 = 21.19, P = 0.968), indicating a similar distribution of recurrent aphthous ulcer between age and sites.

Similarly, the prevalence of recurrent aphthous ulcers according to age and gender is summarized in [Table 3] and also shown in [Figure 3]. In both genders, the prevalence of recurrent aphthous ulcers was higher in lower age groups (11–20 years) as compared to higher age groups (41–80 years). Like sites, the prevalence of recurrent aphthous ulcers also not differed (P > 0.05) between age and genders (χ2 = 8.12, P = 0.323), indicating a similar distribution of recurrent aphthous ulcers among age.

| Discussion|| |
Recurrent aphthous ulcer is the most common disease affecting the oral cavity. Many researchers have attempted to calculate its prevalence, but the results vary in different regions of the world, the range being from 5% to 66%.,, In the present study, the prevalence was found to be 3.93%. This, in comparison to the prevalence reported in other studies done in India, was found to be higher than reported in the South Indian population by Hegde et al. (1.9%) and Mathew et al. (2.1%) and in the Western population of Maharashtra as reported by Rajmane et al. (0.1%), but the prevalence reported in this study was lower when compared to the findings of Patil et al. in North Indian population (21.7%).
Worldwide also, the results of the epidemiological studies are greatly variable. It was estimated to be 40% in the United States of America, 25.2% in Iran, 25.5% in Turkey, 1.4% in Brazil, 28.2% in Iraq, and 78.1% in Jordon. Considerable variation is probably due to genetic factors, socioeconomic level, and lifestyle of individuals of the particular region studied. In the present study, the overall prevalence was found to be higher in the female patients which was in accordance with the results of other researchers.,,,,, Ship et al. stated that higher prevalence in females was due to hormonal changes. On the contrary, Rivera-Hidalgo et al. reported a higher prevalence in males.
The maximum number of cases were reported in the second decade of life (36.76%) and then decreased with the advancing age. Ship et al. and Natah et al. also reported similar results. However, Abdullah18 and Okoh and Ikechukwu found the maximum number of cases in the third decade of life, while Safadi and Patil et al. reported it to peak in the fourth decade of life. The most common site affected was found to be the tongue. Queiroz et al. also reported tongue to be the most common site affected. Other studies have however reported buccal mucosa, to be the most common site. Abdullah reported lips and buccal mucosa to be the most common site.
| Conclusion|| |
Prevalence studies can be used to create and evaluate health-care policies in addition to detecting illness burdens in a population. Aphthous ulcers are prevalent mouth diseases that produce considerable discomfort and have a negative impact on patients' quality of life. Despite this, the exact prevalence of recurring aphthous ulcers in India and around the world is unknown, and the data available are inconsistent. This study gives critical information on the occurrence of recurrent aphthous ulcers and their distribution in different age groups based on gender and site. Even without a proven etiology, it is also extremely important to identify factors associated with recurrence episodes to examine the potential risks of exacerbation of pain symptoms for each patient. More research like this is needed to achieve accurate disease data.
