The effect of diabetes mellitus on oral health-related quality of life: A systematic review and meta-analysis study

Lower Serum IL-10 Linked to Oral Manifestations in Diabetes Patients

Background

Diabetes mellitus (DM) is a chronic disease that remains a global health problem with increasing prevalence, particularly in Indonesia. The presence of oral manifestations in patients with DM is influenced by changes in immune system function. Interleukin-10 (IL-10) is an inflammatory marker implicated in DM. However, no studies have investigated the differences in IL-10 levels between non-DM and DM patients with and without oral manifestations.

Objective

This study aimed to compare the serum levels of IL-10 between non-DM and DM patients with and without oral manifestations at Dr. Hasan Sadikin Hospital Bandung.

Methodology

This observational study used a cross-sectional design. A total of 88 serum samples that met the inclusion criteria were selected, consisting of 37 (42%) samples from non-DM patients, 35 (39.8%) samples from DM patients with oral manifestations, and 16 (18.2%) samples from DM patients without oral manifestations. Serum levels of IL-10 were measured using an enzyme-linked immunosorbent assay (ELISA) kit.

Results

Among the 35 DM patients with oral manifestations, xerostomia was the most common (80%). The mean serum IL-10 level was 0.93 pg/mL in non-DM patients, 0.80 pg/mL in DM patients with oral manifestations, and 1.08 pg/mL in DM patients without oral manifestations. Statistical analysis using the Kruskal-Wallis test showed a p-value of 0.008 (p ≤ 0.05), indicating a significant difference in serum levels of IL-10 between non-DM and DM patients with and without oral manifestations.

Conclusion

DM patients with oral manifestations had lower IL-10 serum levels compared to non-DM patients and DM patients without oral manifestations. These findings suggest that monitoring IL-10 levels could help identify diabetic patients at higher risk for oral complications.

Health and Oral Health-Related Quality of Life and the Associated Factors in Diabetic Patients

BACKGROUND

Diabetes mellitus, a chronic multi-systemic disease affecting various organs, may negatively influence health-related quality of life (HRQoL) and oral health-related quality of life (OHRQoL). This study aimed to investigate this association in a cross-sectional sample of Iraqi Kurdish diabetic patients.

METHODS

Two hundred eighty-five type 2 diabetic patients participated in the survey. The EuroQol-5 Dimensions-5 Levels (EQ-5D-5L) and the Oral Health Impact Profile-5 (OHIP-5) instruments were used to measure HRQoL and OHRQoL, respectively.

RESULTS

For the HRQoL, 75%, 64%, 46%, and 20% of the participants reported "some" problems in the fields of pain/discomfort, anxiety/depression, mobility, and interruption in usual activities, respectively. Concerning the OHRQoL, difficulty in chewing, finding less flavor in food, oral/dental pain, uneasiness about appearance, and difficulty in doing usual activities were the most complained fields of OHRQoL in 35%, 30%, 29%, 25%, and 20% of the patients respectively. Women had significantly worse HRQoL and OHRQoL compared to men. There was a positive, directly proportional, and significant correlation between HRQoL and OHRQoL (Pearson correlation test = 0.455, p = 0.000).

CONCLUSION

Sex, income, duration of diabetes, and smoking were the predictive modifying factors for both HRQoL and OHRQoL. From a public health point of view, raising health awareness is urgently needed among Iraqi diabetic patients for better diabetes management, a healthier lifestyle, and regular oral hygiene measurements.

The association between dental caries, periodontal diseases, and tooth loss with diabetes mellitus among the elderly population

Purpose

Our study investigated the association between dental caries, periodontal diseases, and tooth loss with diabetes mellitus (DM) among the elderly population, representing the first study of its kind in Iran.

Methods

This was a cross-sectional community-based study as a part of the second wave of the Birjand longitudinal aging study (BLAS, 2021-2022) for people older than 60. We used the Comprehensive Geriatric Oral Health Assessment Tool (CGOHAT) for the oral health evaluation. Participants were initially categorized into diabetic and non-diabetic groups. Those patients with DM were further categorised into uncontrolled and controlled diabetes based on their HbA1c level. The association between periodontitis, gingivitis, and edentulism with type II diabetes mellitus and uncontrolled diabetes was assessed using logistic regression.

Results

Among the 1,011 participants, 324 (32.04%) had DM. The mean ± SD DMFT was 27.06 ± 7.71 and 27.07 ± 7.72 among those with and without DM, respectively (p = 0.976). The M index comprised 85.46% of the total DMFT among those without DM and 84.51% among those with DM. The prevalence of periodontitis was higher among those without DM (110, 32.84%, p = 0.390). The prevalence of gingivitis was higher among those with DM (73, 45.06%, p = 0.617). Among the diabetic group, 137 (42.28%) had controlled DM. Based on the adjusted matched multivariate logistic model, decayed teeth (1.24, 95%CI: 1.06 - 1.46, p-value = 0.006), periodontitis (2.78, 95%CI: 1.02 - 7.56, p-value = 0.044), and moderate tooth loss (5.73, 95%CI: 1.13 - 28.88, p-value = 0.034) were significantly associated with increased odds of uncontrolled DM.

Conclusions

Based on the findings of this study, tooth loss was highly prevalent among the elderly Iranians regardless of their diabetes status. Also, periodontitis, tooth loss, and decayed teeth were significantly associated with increased odds of poor glycemic control among those with DM. Thus, it can be concluded that improving the oral health of the geriatric population may be a crucial part of improving the glycemic control among those with diabetes which has been frequently neglected.

Oral Health Education in Patients with Diabetes: A Systematic Review

Diabetes is known as a "silent epidemic" and is a public health problem that accounts for 9% of all deaths worldwide. The prevention of diabetes is a significant challenge, as its prevalence and incidence are both increasing rapidly. According to the World Health Organization (WHO), education is the cornerstone of diabetes treatment. Since the severity of oral diseases is significantly higher in diabetic patients, this systematic review aims to highlight the oral care of diabetic patients as a priority for glycemic control and the importance of education for diabetic patients' oral health. We evaluated 20 clinical studies and 15 meta-analyses from PubMed and Google Scholar over the last five years. Their main themes are the direct relationship between diabetes and oral health, especially periodontitis, and the necessity of education and behaviors that can lead to a better quality of life. Our analysis indicated that good oral health is a critical factor of glycemic control in diabetic patients and can be enhanced by targeted educational programs, backed by long-term medical and dental follow-up. Healthcare personnel should be encouraged to develop their knowledge of oral health in relation to the disease so that behaviors can be adopted to improve patients' quality of life. Telemedicine could also contribute to patient education and self-management of the disease.

The impact of osteogenesis imperfecta severity on oral health-related quality of life in Spain: a cross-sectional study

BACKGROUND

Osteogenesis imperfecta (OI) affects dental and craniofacial development; therefore, it can influence oral health-related quality of life (OHRQoL). The objective of this study was to explore the influence of the severity of OI on OHRQoL in adults older than eighteen years residing in Spain.

METHOD

Adults with OI were recruited from the Spanish Association of Crystal Bone (AHUCE) foundation. OHRQoL was evaluated using the Spanish version of the Oral Health Impact Profile questionnaire (OHIP-14sp), oral hygiene habits, and a dental care survey. Clinical and radiological dental examinations were performed to evaluate the patients' oral conditions.

RESULTS

A total of 65 adults (n = 46 females) aged between nineteen and sixty-two years who were diagnosed with OI and classified as type I, III, and IV (n = 20, 14, and 31, respectively) participated in this research. The total OHIP-14sp scores were significantly greater (worse) for type III (23 [SD = 10]) and type IV (21.4 [SD = 12]) than for type I (13.8 [SD = 6]) (P < 0.05). The negative impact of OHRQoL was due to the association of type III OI with all domains except for the handicap domain, while type IV OI was associated with the physical disability, social disability, and handicap domains (P < 0.05 for all).

CONCLUSION

The severity of OI negatively impacted OHRQoL in adults. This association was statistically significant.

Exploring Interleukin-10 Levels in Diabetes Patients with and without Oral Diseases: A Systematic Review

Aim

Interleukin-10 (IL-10) is a cytokine that plays an important role in the progression of diabetes mellitus (DM). Oral diseases were more common in diabetics than in non-diabetics. The aim of this review is to identify IL-10 levels in diabetic patients with and without oral diseases.

Methods

A systematic review was conducted based on the PRISMA guidelines. Three databases (PubMed, Cochrane Library, and Science Direct) were used to search for articles up to November 2023 for studies on the measurement of IL-10 in diabetics with and without oral disease. The criteria were limited to human studies and full-text in English only. The outcome was the value of IL-10. The study was quality-graded using the Risk of Bias Assessment Tool for Non-randomized Studies (RoBANS).

Results

There were eleven articles that met the eligibility criteria for analysis. Four articles discovered higher IL-10 levels, while seven articles discovered lower IL-10 levels in diabetes patients with oral diseases compared with each control group.

Conclusion

Most studies showed lower IL-10 levels in diabetic patients with oral diseases compared with the control group.

Health-related quality of life aspects of the 'Periodontitis prevalence in ulcerative colitis and Crohn's disease' (PPCC) cohort

AIM

To assess whether oral health problems affect disease-specific quality of life (QoL) of inflammatory bowel disease (IBD) patients, and vice versa, whether IBD affects oral-health-related QoL.

MATERIALS AND METHODS

Individuals reporting IBD and matched controls were surveyed on general anamnestic information, oral-health-related questions and the Oral Health Impact Profile (OHIP)-5. IBD patients were additionally surveyed on years since diagnosis, disease activity and severity as well as health-related QoL (Short Inflammatory Bowel Disease Questionnaire, sIBDQ). OHIP-5 and sIBDQ were defined as primary outcome parameters, and several predictors and confounders were used in adjusted univariable and multivariable regression analyses.

RESULTS

Answers from 1108 IBD patients and 3429 controls were analysed. Compared with controls, IBD patients reported significantly more frequently an oral impact on daily life and worse oral-health-related QoL, with Crohn's disease (CD) patients being more severely affected than ulcerative colitis (UC) patients. The diagnosis of UC and CD, having <20 teeth, severe periodontitis and stressful daily-life experience were associated with a higher prevalence of poor oral-health-related QoL. Among IBD patients, an impaired IBD-specific, health-related QoL was significantly associated with the diagnosis of CD and depression, IBD activity and severity, having <20 teeth, presence of oral lesions and stressful daily-life experience, while a longer time since diagnosis was significantly associated with an improved IBD-specific, health-related QoL.

CONCLUSIONS

The results of the present study indicate, for the first time, that oral health problems are associated with an impairment of IBD-specific health-related QoL, and vice versa, IBD is associated with an impaired oral health-related QoL. This emphasizes the potential advantages of including dental professionals in the multi-disciplinary treatment teams of IBD patients.
