Abstract
Despite the worldwide recognition of the dangers of diabetes mellitus, diabetic patients’ awareness of and
attitudes toward their heightened risk for oral diseases has not been fully addressed. Oral hygiene behavior and
seeking oral health care depend on a number of factors. Lack of knowledge about dental health and comply
better with hygiene is among the reasons for non-adherence to oral hygiene practices, economical constrains,
lack of facilities and lack of proper guidance. The Purpose of this study was to assess the knowledge and
awareness of diabetic patients about their risk for oral diseases as complications associated with diabetes, and to
assess their attitudes and practices toward sustaining good oral health through proper oral hygiene and regular
dental check-ups. A cross sectional study was conducted including 612 diabetic patients visiting the primary
health care centers in abha city. Results showed that More than half of the included patients (52.3%) were not
aware that diabetic patients are more prone to oral diseases and only less than half of them (46.1%) and (46.4%)
knew that DM. cause dental caries and affect gingival. The level of awareness and dental health knowledge in
diabetic patients was deficient. Most diabetic patients knew about various medical complications of diabetes and
the effect of DM on the body systems. About the attitude and practice of the diabetic patients towards oral health,
the overall oral hygiene measures in diabetic patients were found to be good.

1. Introduction
Diabetes mellitus (DM) is a group of metabolic disorders characterized by hyperglycemia. It is associated with
abnormalities in carbohydrate, fat, and protein metabolism, and results in chronic complications, including
microvascular, macrovascular, and neuropathic disorders. (1). Diabetes mellitus (DM) is increasing in prevalence
worldwide, reaching the status of an epidemic and costing healthcare services significant amounts of money in
direct and indirect costs. The total number of people with diabetes is projected to rise from 171 million in 2000
to 366 million in 2030, while in developing countries the prevalence is projected to double between 2000 and
2030 (2) according to the (who), at least 220 million people or 2.8% of the population worldwide suffer from
diabetes. Its incidence is increasing rapidly, and is estimated that by the year 2030, this number will almost
double. The greatest increase in prevalence is expected to occur in asia and africa. The increase in incidence of
diabetes in developing countries follows the trend of urbanization and lifestyle changes (3).
diabetes mellitus is associated with many micro and macrovascular complications in the body.in addition to
these, oral complications and manifestations in the form of gingivitis, periodontitis, xerostomia, opportunistic
infections, greater accumulation of plaque, delayed wound healing, oral paresthesia, and altered taste and
candidiasis are also becoming the emerging problem in dental health sector and has a very important impact on
the social and economical sectors of the countries. (4).
There has been a growing evidence showing that patients with diabetes have higher severity of periodontal
disease. They are 2-3 times more likely to have periodontitis as compared to non-diabetic patients which is
related to long term metabolic control and disease duration (5). Studies have proved a bidirectional adverse
relationship between diabetes and periodontal disease; diabetes can aggravate periodontitis, and periodontitis can
negatively affect control of diabetes (6,7)
Preventive measures like regular proper brushing, flossing, and periodic dental visits should be ensured , which
will not only prevent so many complications due to diabetes but will also decreases the morbidity due to these
manifestations. Oral hygiene behaviour and seeking oral healthmcare depend on a number of factors (8,.9)
Lack of knowledge about dental health and hygiene is among the reasons for non-adherence to oral hygiene
practices due to illetracy, economical constrains,lack of facilities and lack of proper guidance (10)
Oral health attitudes and beliefs are significant for oral health behavior. A higher likelihood of seeking preventive
dental care is found to be associated with dental
Knowledge , so health education attempts to change behaviors by altering an individual’s knowledge, attitudes,
and beliefs about health matters . (11,12)

Misconceptions or incorrect knowledge about oral health may actually lead to harmful behaviors. For example,
instead of brushing and flossing more often, people with diabetes may believe they should stop brushing or
flossing when their gums bleed while brushing; or people with diabetes exhibiting dry mouth may not know that
using mouth rinse containing alcohol to improve oral hygiene actually increases mouth dryness. These
misconceptions and incorrect information about oral health could act as major barriers to efficient prevention and
management of oral disease in this high-risk population.(13)
Despite the worldwide recognition of the dangers of diabetes mellitus, diabetic patients’ awareness of and
attitudes toward their heightened risk for oral diseases has not been fully addressed (14)
A study by allen et al. Assessed the knowledge of diabetic patients about their risk for periodontal disease, their
attitude toward oral health, and their oral health-related quality of life. The researchers found that only 33% of
the participants were aware of their increased risk for periodontal disease (15). Similarly, eldarrat (16) found that
diabetic patients’ awareness of their increased risk for oral diseases was low compared to their awareness of
systemic diseases and a significant association was found between glycemic control and oral infections.
Furthermore, moore et al. (17assessed oral health attitudes, behaviors, and knowledge of participants with type 1
diabetes and found that most of the participants were unaware of the oral health complications of diabetes
mellitus and the need for preventive care.
Unfortunately, caring for the oral cavity is often overlooked when trying to control other problems associated
with diabetes which may contribute to hidden morbidity and undue suffering from oral health problems. Baseline
data on knowledge levels are required to determine which particular areas of oral health education are in need of
improvement for this vulnerable population
2. Objectives
1. To assess the knowledge and awareness of diabetic patients of their risk for oral diseases as complications
associated with diabetes,
2. to assess their attitudes and practices toward sustaining good oral health through proper oral hygiene and
regular dental check-ups
3.Methodology
This study is a cross sectional descriptive survey of 612 diabetic patients visiting the primary health care centers
in abha city.
Patients included in the study were patients suffering from type 1 or type 2 diabetes of all age groups, having at
least one natural tooth, and having been diagnosed with diabetes for at least 6 months formed the inclusion
criteria. Diabetic medical personnel or who were apparently physically or mentally handicapped were excluded
from the study.
a questionnaire was designed to assess the knowledge, attitude, and practices of diabetic patients along with
corresponding demographic variables.
After taking informed consent from each eligible participant before administration of the questionnaire, willing
participants were informed in details by the investigators about the research project and its consequences.
Privacy of the patients was ensured during filling of questionnaires.
At the end of questioning, patients were informed about the impact of their systemic condition on oral health and
were given a health education booklet.
The data were analyzed using spss version 20. Comprehensive descriptive statistics were produced for all
demographic and KAP variables.
4.Results
A total of 612 patients fulfilling the inclusion and exclusion criteria were enrolled into the study . 274 (44.8%)
were males and 338 (55.2%) were females. The median age of the included patients was 56.00. The distribution
of diabetic patients according to the sociodemographic characteristics is shown in table (1):

About the attitude and practice of the diabetic patients towards oral health, 77.5% of them will consult a dentist
if they had an oral health problem while only 8.5% will use self remedy or ignore it. Most of the included
patients (83.2%) brush their teeth. As regards to the frequency of teeth brushing, 26.2% brush occasionally or no
brushing. More than two thirds (68.5%) of the patients visit the dentist once a year while 7.8% of them did not
visit the dentist at all. About two thirds (65.8%) of the patients want to get education about the effect of diabetes
on oral health.
5.Discussion
Diabetes has a negative impact on the patient's health due to its many complications. Diabetic patients develop
complications due to lack of awareness of the diseasel. There is increasing amount of evidence that patient
education is the most effective way to lessen the complications of diabetes.(18)
A total of 612 patients were enrolled into this study. Female patients were more in number than females and the
maximum number of patients were in the age-group of more than 55 years. This is similar to the study carried
out in western nepal by dinesh et al.(19)
This study showed that there is lack of awareness about the relationship of diabetes with oral complications. And
more than half of the participants did not have adequate oral health knowledge related to diabetes. The results are
consistent with studies conducted in saudi arabia and worldwide (20,21,22). This may indicate lack of oral health
counseling on the part of physicians and
Illiteracy
In the present study,it was found that less than a fourth of the respondents were aware of . (signs of gingival
diseases like bleeding during brushing, swollen red colored gingiva and soreness of gingival. These results are in
accordance with previous studies (17,23)
This study revealed that most diabetic patients knew about various medical complications of diabetes and the
effect of DM on the body systems like the eyes ( retinopathy), kidneys (nephropathy), nerves (neuropathy), the
heart and diabetic foot because their physicians had laid emphasis on these topics. This may indicate lack of oral
health counseling on the part of physicians, as evidenced by other studies (24,25).
About the attitude and practice of the diabetic patients towards oral health, the overall oral hygiene measures in
diabetic patients were found to be good in this study. Most of the included patients consult the dentist, brush
23

their teeth at least 0nce daily and regularly visit the dentist at least once a year for check up. .these findings are
in agreement with fatin and rehana studies (20,25). On the other hand these findings are in disagreement with
kamran study in pakistan (21) who found that overall oral hygiene measures in diabetic patients were deficient ,
this may be due to lack of health education about oral hygiene.
6. Conclusion
The level of awareness and dental health knowledge in diabetic patients was deficient. Most diabetic patients
knew about various medical complications of diabetes and the effect of DM on the body systems. About the
attitude and practice of the diabetic patients towards oral health, the overall oral hygiene measures in diabetic
patients were found to be good.
