Abstract
Denture stomatitis and angular cheilitis is a form of oral candidiasis. It is a common opportunistic infection in diabetic patients.
Presence of denture in the oral cavity of diabetic patients can increase the incidence of denture stomatitis and angular cheilitis.
The aim of our study was to assess the diabetic status among the patients with denture stomatitis and angular cheilitis. This study
is a Retrospective study conducted in a University hospital setting. The study population consists of 99 patients with denture
stomatitis and angular cheilitis who had reported to the department of Oral Medicine and Radiology, Saveetha Dental College
and Hospitals, Chennai, India. The data regarding the age, gender, diabetic status and clinical presentation of the patients were
retrieved from patients records and analysed. The data with a total 86000 patients records between June2019 to March 2020
were taken and after fulfillment of inclusion and exclusion criteria, a final sample of 99 patients were considered.The data were
tabulated and analysed by SPSS software and statistics done using Chi Square test with significance kept at p<0.05. Prevalence of
diabetic patients was found to be 15.1% among the study population. The prevalence of diabetic patients with Denture stomatitis
was 11.1% and angular cheilitis was 4%. Lesser number of patients with denture stomatitis and angular cheilitis were found to be
diabetic Chi square p value-0.095(p>0.05). It was observed that prevalence of diabetic patients was found to be very less among
the study population and no significant association was seen between diabetes and candida related lesions such as denture stomatitis
and angular cheilitis.

Introduction
Diabetes mellitus is a common and growing global health problem
which causes several complications. Diabetes has an increased
predisposition to the manifestation of oral disease like
candidiasis, denture stomatitis and angular cheilitis which are associated
with poor glycemic control and therapeutic dentures [1].
This predisposition also contributes to xerostomia, which may be
due to increased glucose levels. Wearing complete dentures is also
known as a risk factor, which can promote Colonization of candida,
produce candida biofilm and result in oral candidiasis [2].
Association of denture and diabetes can increase the incidence of
oral candida disorders in diabetic patients [1, 3].
Diabetes mellitus is a chronic metabolic disease, which causes
several disorders [2, 4]. Immunodeficiency and increased susceptibility
to opportunistic infections are seen in diabetic patients.
Colonization of candida is more prevalent in people with diabetes
mellitus [1, 2]. Many studies have shown a higher prevalence of
candidal colonization in the oral cavity of diabetes when compared
to non-diabetic individuals [5, 6]. In addition, a significantly
higher prevalence of oral candidiasis in people with diabetes is
reported [7].
Candidal infection is found commonly in denture wearers [8]. Acrylic dentures are an important predisposing factor for oral
candidosis as these appliances, which are usually ill fitting with
suboptimal hygiene, act as reservoirs of infection. It is also reported
that high salivary yeast counts are much more common
in complete denture wearers than indentate individuals [9] Commensal
existence of intra oral candida species varies from 20%
to 50% in a healthy edentulous population and up to 75% in
denture-wearers [10]. The manifestation of oral candidiasis can
occur in many different forms including median rhomboid glossitis,
atrophic glossitis, denture stomatitis and angular cheilitis. Candidiasis
is associated with a high density of yeasts in lesions [11].
Denture stomatitis is a term used to describe inflammatory
changes in the oral mucosa of denture bearing tissues 11. These
changes are characterized by erythema and are found under complete
or partial dentures in both jaws, but more frequently in the
maxilla [12]. According to the clinical aspects of the lesions, Newton
classified denture stomatitis as pinpoint hyperaemia (type I),
diffuse erythematous hyperaemia (type II) and granular hyperaemia
(type III) [13].
Angular cheilitis is the clinical diagnosis of deep fissures affecting
the angles of the mouth and has an ulcerated appearance [14].
Etiological factors in relation to angular cheilitis are infection, low
vertical vertical dimension , prolonged use of antibiotics, sensitivity
to denture materials, vitamin deficiencies etc [15]. The aim of
the study is to assess the diabetic status in denture stomatitis and
angular cheilitis.
Materials and Methods
This study is a single- centred retrospective study, carried out in a
private dental college. The present study was approved by Institutional
ethical committee [IEC] (Ethical approval number: SDC/
SIHEC/2020/DIASDATA/0619-0320) and was in accordance
with the ethical standards that were stipulated. All available records
of patients from June 2019 - April 2020 were examined
and a total of 86000 case sheets were reviewed. Patients above 18
years and those with candida related lesions such as denture stomatitis
and angular cheilitis were included in the study. Those who
visited outside the time frame, with other candida associated lesions
were excluded from the study. Cross verification of data for error was done by presence of additional reviewers and by photographs
evaluation. Two examiners were involved in the study. Any
patient with incomplete data was excluded from the study.
Acquisition of data was done from the hospital database which
records all patient details. The study included 99 patients with
denture stomatitis and angular cheilitis. The collected data were
grouped based on denture stomatitis and angular cheilitis .Age
was categorised into 18 - 35 years, 36- 55 years and older than
55 years. Gender was categorised into males and females. The
medical history of the patients with denture stomatitis and angular
cheilitis were verified to assess the diabetic status in the study
population.The data were entered in the system in a methodical
manner. For this study, data regarding age, gender and diabetic
status of the patients were collected. The data was then entered in
excel manually and imported to SPSS for analysis. Incomplete or
censored data were excluded from the study.
The statistical analysis was done using SPSS software (SPSS version
21.0, SPSS, Chicago II, USA). Descriptive statistics was used
to summarise the demographic information of the patients included
in this study. Descriptive statistics is used for the acquisition
of frequency distribution of the data. Chi-square test was
applied to analyse the association of different variables. Statistical
significance was kept at p<0.05.
Results and Discussion
The study population consists of 99 patients above 18 years of
age. Based on the distribution of study population by age, 15.1%
of the patients were found within the age group of 18 - 35 years,
43.4% of the patients were found in the age group of 35 - 55
years and 41.4% of the patients were found over 55 years of age(
Figure 1). Based on the distribution of population by gender,
47.4% of the patients were found to be males and 52.5% of the
patients were found to be females (Figure 2). Based on the diabetic
status of the patients, 15.1% of the patients were found to be
diabetic and 84.1% of the patients were found to be non- diabetic (Figure 3). Based on the prevalence of types of denture stomatitis
among diabetic patients, 54.5% of the diabetics patients were
found to present with Type II denture stomatitis and 45.4% of
the diabetic patients were found to present with Type I denture
stomatitis (Figure 4).

Dorocka et al observed that 57.3% of diabetic patients had type II denture stomatitis [16]. This is similar to the results of our current study where 54.5% of diabetic patients had type II denture stomatitis. In a study of 463 randomly selected geriatric denture wearers, the prevalence of denture stomatitis was to be high as 65% [17] and these lesions are seen more frequently among women than men, which is in accordance with our study were denture stomatitis was more common in females. Axell et al says that prevalence of angular cheilitis is more frequently seen in women than in men [18] which is in contrast to our study where angular cheilitis is more common in males. The prevalence of angular cheilitis among complete dentures wearers has been shown to vary between 8 and 30% [19, 16]. Rahmi et al., observed that prevalence of diabetes is high (65%) in the patients with angular cheilitis [20]. However, this is not similar to our result where only 4% of the diabetic patients had angular cheilitis. In a study conducted by Makila et al., it was observed that, in diabetic patients the prevalence of denture stomatitis was found to be as high as 75% [21], which does not support our result where only 11.1% of the patients were found with denture stomatitis. Literature says, people with type ll diabetes mellitus stand a higher risk of developing denture stomatitis than the non-diabetics [22].
In a study, the prevalence of denture stomatitis was found to be significantly higher in diabetic patients than in control subjects (P = 0.018) [23]. A literature search revealed conflicting reports about the association of denture stomatitis with diabetes mellitus [24]. A study reported that the prevalence of angular cheilitis was found to be significantly higher in diabetic patients than in control subjects (P < 0.05) [25], but our study results are contrary to the previous literature. It is generally acknowledged that diabetic patients are more susceptible to fungal infections, particularly to Candida albicans infections, than non-diabetic subjects [26]. Hyperglycemia due to poor metabolic control is one possible predisposing factor of oral candidiasis in diabetic patients. This can lead to the growth of Candida albicans and enhanced adhesiveness to the oral epithelium 21 in association with other local factors such as the presence of dental prostheses, salivary pH, salivary flow rate, and oral habits [26].
Thus, the current study is not in accordance with the previous literature, this evidence adds to the consensus and can be used in diagnosis in a clinical practice. Previously our team had conducted numerous clinical trials [27-31] and lab studies [32-36] and in vitro studies [37-41] over the past 5 years. The limitations of the study could be smaller sample size. However, for better results and significance, cohort study can be done to assess the diabetic status among the patients with denture stomatitis and angular cheilitis on a larger sample size.
Conclusion
Within the limits of the study it was observed that, 15.1% of
the patients with denture stomatitis and angular cheilitis were diabetic.
Type II denture stomatitis were more common in diabetic
patients.There was no significant association of diabetic status
with denture stomatitis and angular cheilitis patients. However,
glycemic levels should be monitored regularly in patients with diabetes
to prevent candida associated lesions.
