Assessment and management of patients with diabetes mellitus in the dental office

Diabetes Mellitus and Its Influence on Oral Health: Review

Diabetes mellitus (DM) is one of the most common diseases all over the world. The effect of this endocrine disease on body systems cannot be ignored, where its oral side effects are well distinguished. As this disease incident is increasing dramatically, it is essential for the health care providers to be fully aware of the disease diagnosis, management and to deal with it in a full confident. This review discusses the disease itself, its complications, methods of diagnosis as well as its management. Furthermore, oral manifestations and dental considerations that should be followed when treating patients with diabetes mellitus have been discussed in this review.

Diabetes and Oral Health: Summary of Current Scientific Evidence for Why Transdisciplinary Collaboration Is Needed

This Perspective provides a brief summary of the scientific evidence for the often two-way links between hyperglycemia, including manifest diabetes mellitus (DM), and oral health. It delivers in a nutshell examples of current scientific evidence for the following oral manifestations of hyperglycemia, along with any available evidence for effect in the opposite direction: periodontal diseases, caries/periapical periodontitis, tooth loss, peri-implantitis, dry mouth (xerostomia/hyposalivation), dysbiosis in the oral microbiome, candidiasis, taste disturbances, burning mouth syndrome, cancer, traumatic ulcers, infections of oral wounds, delayed wound healing, melanin pigmentation, fissured tongue, benign migratory glossitis (geographic tongue), temporomandibular disorders, and osteonecrosis of the jaw. Evidence for effects on quality of life will also be reported. This condensed overview delivers the rationale and sets the stage for the urgent need for delivery of oral and general health care in patient-centered transdisciplinary collaboration for early detection and management of both hyperglycemia and oral diseases to improve quality of life.

Rocha C, V. Maurer-Morelli C, Perez Orrico SR, Cirelli JA, Von Zuben FJ, Mantuaneli Scarel-Caminaga R. Using association rule mining to jointly detect clinical features and differentially expressed genes related to chronic inflammatory diseases

OBJECTIVE

It is increasingly common to find patients affected by a combination of type 2 diabetes mellitus (T2DM), dyslipidemia (DLP) and periodontitis (PD), which are chronic inflammatory diseases. More studies able to capture unknown relationships among these diseases will contribute to raise biological and clinical evidence. The aim of this study was to apply association rule mining (ARM) to discover whether there are consistent patterns of clinical features (CFs) and differentially expressed genes (DEGs) relevant to these diseases. We intend to reinforce the evidence of the T2DM-DLP-PD-interplay and demonstrate the ARM ability to provide new insights into multivariate pattern discovery.

METHODS

We utilized 29 clinical glycemic, lipid and periodontal parameters from 143 patients divided into five groups based upon diabetic, dyslipidemic and periodontal conditions (including a healthy-control group). At least 5 patients from each group were selected to assess the transcriptome by microarray. ARM was utilized to assess relevant association rules considering: (i) only CFs; and (ii) CFs+DEGs, such that the identified DEGs, specific to each group of patients, were submitted to gene expression validation by quantitative polymerase chain reaction (qPCR).

RESULTS

We obtained 78 CF-rules and 161 CF+DEG-rules. Based on their clinical significance, Periodontists and Geneticist experts selected 11 CF-rules, and 5 CF+DEG-rules. From the five DEGs prospected by the rules, four of them were validated by qPCR as significantly different from the control group; and two of them validated the previous microarray findings.

CONCLUSIONS

ARM was a powerful data analysis technique to identify multivariate patterns involving clinical and molecular profiles of patients affected by specific pathological panels. ARM proved to be an effective mining approach to analyze gene expression with the advantage of including patient's CFs. A combination of CFs and DEGs might be employed in modeling the patient's chance to develop complex diseases, such as those studied here.

Factors associated with additional time dental hygienists spent on educating patients with diabetes

AIMS

To investigate what dental hygienists' practice characteristics and oral health topics are associated with additional time dental hygienists spent on educating patients with diabetes.

METHODS

A one-page survey was mailed to 2237 registered dental hygienists in South Carolina. Survey questions focused on perceptions of dental hygienists regarding their oral health preventive education for patients with diabetes. After two follow-up mails, we received 995 usable questionnaires.

RESULTS

Multivariable logistic regression modeling showed dental hygienist respondents who spent additional time educating patients with diabetes about oral health felt they had adequately covered the topics on effects of periodontal disease related to diabetes, effects of uncontrolled diabetes on periodontal disease, and nutrition and dietary counseling. In addition, a higher number of patients with diabetes treated per week, and a shorter recall interval for patients were also associated with more likelihood of respondents spending additional time educating patients with diabetes.

CONCLUSION

Results suggest that the additional time that dental hygienist respondents spent on educating patients with diabetes was related to oral health issues associated with diabetes, not just repetition of routine oral hygiene and plaque control instructions.

Screening for Diabetes Risk Using Integrated Dental and Medical Electronic Health Record Data

Undiagnosed diabetes and prediabetes present a serious public health challenge. We previously reported that data available in the dental setting can serve as a tool for early dysglycemia identification in a primarily Hispanic, urban population. In the present study, we sought to determine how the identification approach can be recalibrated to detect diabetes or prediabetes in a White, rural cohort and whether an integrated dental-medical electronic health record (iEHR) offers further value to the process. We analyzed iEHR data from the Marshfield Clinic, a health system providing care in rural Wisconsin, for dental patients who were ≥21 y of age, reported that they had never been told they had diabetes, had an initial periodontal examination of at least 2 quadrants, and had a glycemic assessment within 3 mo of that examination. We then assessed the performance of multiple predictive models for prediabetes/diabetes. The study outcome, glycemic status, was gleaned from the medical module of the iEHR based on American Diabetes Association blood test cutoffs. The sample size was 4,560 individuals. Multivariate logistic regression revealed that the best performance was achieved by a model that took advantage of the iEHR. Predictors included age, sex, race, ethnicity, number of missing teeth, percentage of teeth with at least 1 pocket ≥5 mm from the dental EHR, and overweight/obesity, hypertension, hyperlipidemia, and smoking status from the medical EHR. The model achieved an area under the receiver operating characteristic curve of 0.71 (95% confidence interval, 0.69-0.72), yielding a sensitivity of 0.70 and a specificity of 0.62. Across a range of populations, informed by certain patient characteristics, dental care team members can play a role in helping to identify dental patients with undiagnosed diabetes or prediabetes. The accuracy of the prediction increases when dental findings are combined with information from the medical EHR. Knowledge Transfer Statement: Prediabetes and diabetes often go undiagnosed for many years. Early identification and care can lead to improved glycemic outcomes and prevent wide-ranging morbidity, including adverse oral health consequences, in affected individuals. Information available in the dental office can be used by clinicians to identify those who remain undiagnosed or are at risk; the accuracy of this prediction increases when combined with information from the medical electronic health record.

Status Update on Translation of Integrated Primary Dental-Medical Care Delivery for Management of Diabetic Patients

Escalating prevalence of both diabetes and periodontal disease, two diseases associated with bi-directional exacerbation, has been reported. Periodontal disease represents a modifiable risk factor that may reduce diabetes onset or progression, and integrated models of cross-disciplinary care are needed to establish and manage glycemic control in affected patients. An ad-hoc environmental scan of current literature and media sought to characterize factors impacting status of integrated care models based on review of the existing evidence base in literature and media surrounding: (1) current cross-disciplinary practice patterns, (2) epidemiological updates, (3) status on risk assessment and screening for dysglycemia in the dental setting, (4) status on implementation of quality metrics for oral health, (5) care model pilots, and (6) public health perspectives. The survey revealed: escalating prevalence of diabetes and periodontitis globally; greater emphasis on oral health assessment for diabetic patients in recent medical clinical practice guidelines; high knowledgeability surrounding oral-systemic impacts on diabetes and growing receptivity to medical-dental integration among medical and dental providers; increasing numbers of programs/studies reporting on positive impact of emerging integrated dental-medical care models on diabetic patient healthcare access and health outcomes; a growing evidence base for clinically significant rates of undiagnosed dysglycemia among dental patients reported by point-of-care pilot studies; no current recommendation for population-based screening for dysglycemia in dental settings pending a stronger evidence base; improved definition of true periodontitis prevalence in (pre)/diabetics; emerging recognition of the need for oral health quality indicators and tracking; evidence of persistence in dental access disparity; updated status on barriers to integration. The potential benefit of creating clinically-applicable integrated care models to support holistic management of an escalating diabetic population by targeting modifiable risk factors including periodontitis is being recognized by the health industry. Cross-disciplinary efforts supported by high quality research are needed to mitigate previously- and newly-defined barriers of care integration and expedite development and implementation of integrated care models in various practice settings. Implementation of quality monitoring in the dental setting will support definition of the impact and efficacy of interventional clinical care models on patient outcomes.

Non-antibacterial tetracycline formulations: host-modulators in the treatment of periodontitis and relevant systemic diseases

Traditionally, the dental profession has primarily treated periodontitis using a mechanical/surgical, rather than a pharmaceutical, approach. However, based on experiments several decades ago which demonstrated that tetracyclines, unexpectedly, inhibit collagen- and bone-destructive mammalian-derived enzymes (e.g. the collagenases), and through non-antibiotic mechanisms, the concept of host-modulation therapy (HMT) was developed. Accordingly, two drug-development strategies evolved: (i) the development of non-antimicrobial formulations of doxycycline; and (ii) the chemical modification of tetracyclines to eliminate their antibiotic activity but retain (or even enhance) their anti-collagenase properties. Regarding the latter, these chemically modified tetracyclines (CMTs) showed efficacy in vitro, in animal models of periodontal (and relevant systemic) disease, and in preliminary clinical trials on patients with Kaposi's sarcoma (however, at the high doses used, photosensitivity was a significant side-effect). In the first strategy, subantimicrobial-dose doxycycline (SDD) demonstrated safety and efficacy in human clinical trials and was approved by the U S Food and Drug Administration (U S FDA) and in other countries for the treatment of periodontitis (20 mg, twice daily, i.e. once every 12 hours) adjunctive to scaling and root planing, and for chronic inflammatory skin diseases (40-mg sustained-release 'beads'). SDD also showed efficacy in patients with systemic diseases relevant to periodontitis, including diabetes mellitus and arthritis, and in postmenopausal women with local and systemic bone loss. Importantly, long-term administration of SDD, of up to 2 years, in clinical trials did not produce antibiotic side-effects. SDD (and in the future, new HMTs, such as low-dose CMT-3, resolvins and chemically modified curcumins) may shift the paradigm of periodontal therapy from a predominantly surgical approach to the greater use of medicinal/pharmacologic strategies, ultimately to benefit larger numbers of patients.

Indian patients' attitudes towards chairside screening in a dental setting for medical conditions

BACKGROUND

India has a high prevalence of cardiovascular disease (CVD), diabetes mellitus (DM), tuberculosis (TB), human immunodeficiency virus/acquired immune-deficiency syndrome (HIV/AIDS) and hepatitis B. United States-based studies indicate provider and patient support for medical screening in the dental setting. We assessed patient attitudes towards, and willingness to participate in, medical screening in the dental setting in India.

METHOD

A 5-point Likert scale survey (with scores ranging from 1=very important/willing to 5=very unimportant/unwilling) was given to a convenience sample of adult patients visiting five university-based dental clinics (clinic group) and one private-practice setting (private group). The Mann-Whitney U-test was used to compare mean response scores between patient groups. Logistic regression was used to assess factors associated with a favourable outcome.

RESULTS

Both patient groups felt it important for dentists to identify increased risk for medical conditions (89.3% vs. 94.9%, respectively; P=0.02). The majority of patients were willing to have a dentist screen for the specified conditions: CVD (80.6% clinic and 84.5% private); DM (84.5% clinic and 77.5% private); TB (76.7% clinic and 73.2% private); hepatitis (73.3% clinic and 67.5% private); and HIV/AIDS (71.0% clinic and 70.5% private). The majority of patients were willing to participate in chairside screening that yielded immediate results (84.6% clinic and 86.1% private), discuss results immediately (85.8% clinic and 87.2% private) and pay 150 Indian rupees (55.9% clinic and 91.7% private). Younger patients (<40 years of age) were significantly less likely to respond favourably to: importance of medical screening in dental settings [adjusted odds ratio (OR)=0.63; 95% confidence interval (95% CI): 0.26-0.84] and be available for screening that yielded immediate results (adjusted OR=0.63; 95% CI: 0.40-0.99).

CONCLUSIONS

Indian dental patients were in favour of chairside medical screening.

Illness perceptions among adults at risk for diabetes

PURPOSE

The purpose of this study is to examine diabetes illness perceptions among a sample of at-risk adults according to specific characteristics that make them vulnerable to diabetes.

METHODS

At-risk adults (N = 372) participated in a study investigating the potential to screen them for diabetes at a large urban dental college. Sociodemographic and individual-level diabetes risk-related characteristics, A1C measures, diabetes-related symptoms, diabetes knowledge, diabetes illness perceptions, and perceived causes of diabetes were collected and reported for the study sample; t tests were then used to determine whether there were statistically significant differences in each of 8 dimensions of diabetes illness perceptions according to the presence or absence of 6 diabetes risk factors.

RESULTS

Average A1C values were 5.6% (38 mmol/mol), and 46% of the study sample had A1C values in the prediabetes or diabetes range. Participants had various diabetes knowledge gaps and misperceptions, and there were differences in dimensions of diabetes illness perceptions depending on specific diabetes-related risk factors.

CONCLUSIONS

In view of differences in the diabetes-related illness perceptions of persons at risk for diabetes, it is important for diabetes educators and other health care providers to personalize their diabetes-related education, management, and support to the specific needs and vulnerabilities of at-risk patients.

Hypoglycemic activity and acute oral toxicity of chromium methionine complexes in mice

The hypoglycemic activity of chromium methionine (CrMet) in alloxan-induced diabetic (AID) mice was investigated and compared with those of chromium trichloride hexahydrate (CrCl3·6H2O) and chromium nicotinate (CrNic) through a 15-day feeding experiment. The acute oral toxicity of CrMet was also investigated in ICR (Institute for Cancer Research) mice by a single oral gavage. The anti-diabetic activity of CrMet was explored in detail from the aspects of body weight (BW), blood glucose, triglyceride, total cholesterol, liver glycogen levels, aspartate transaminase (AST) and alanine transaminase (ALT) levels. The obtained results showed that CrMet had beneficial effects on glucose and lipid metabolism, and might possess hepatoprotective efficacy for diabetes. Daily treatment with 500 and 1000μg Cr/kg BW of CrMet in AID mice for 15 days indicated that this low-molecular-weight organic chromium complex had better bioavailability and more beneficial effects on diabetics than CrCl3·6H2O. CrMet also had advantage over CrNic in the control of AST and ALT activities. Acute toxicity studies revealed that CrMet had low toxicity potential and relatively high safety margins in mice with the LD50 value higher than 10.0g/kg BW. These findings suggest that CrMet might be of potential value in the therapy and protection of diabetes.

Association between oral health status and type 2 diabetes mellitus among Sudanese adults: a matched case-control study

AIM

The purpose of this study was to compare the clinical and subjective oral health indicators of type 2 diabetic patients (T2DM) with age and gender matched non-diabetic controls. A second aim was to identify clinical and subjective oral health indicators that discriminate between well-controlled and poorly controlled T2DM patients as well as between patients with long and short duration of the disease.

METHODS

A total of 457 individuals participated in the study (154 T2DM cases and 303 non-diabetic controls). The T2DM group was sub-divided according to metabolic control [(well-controlled: glycosylated haemoglobin test 8%), (poorly controlled: glycosylated haemoglobin test > 8%)] and according to duration of T2DM [(long duration: >10 years), (short duration: 10 years)]. Participants were interviewed using a structured questionnaire including socio-demographics, lifestyle and oral health related quality of life factors. The clinical examination comprised full mouth probing depths, plaque index, tooth mobility index, furcation involvement and coronal and root surface caries.

RESULTS

The T2DM patients presented with more probing depths 4 mm, furcation involvement, tooth mobility, missing teeth, and oral impacts on daily performance (OIDP). The corresponding adjusted odds ratios and their 95% confidence intervals were 4.07 (1.74-9.49), 2.96 (1.36-6.45), 5.90 (2.26-15.39), 0.23 (0.08-0.63) and 3.46 (1.61-7.42), respectively. Moreover, the odds ratio was 2.60 (1.21-5.55) for the poorly controlled T2DM patients to have high levels of mobility index and 2.94 (1.24-6.94) for those with long duration of T2DM to have high decayed, missed and filled teeth (DMFT) values.

CONCLUSION

This study revealed that chronic periodontitis, tooth mobility, furcation involvement and OIDP were more prevalent among T2DM patients compared to their non-diabetic controls.
