Abstract
Saliva is a readily accessible and inexpensive biological specimen that enables investigation of the oral microbiome, which can serve as a biomarker of oral and systemic health. There are two routine approaches to collect saliva, stimulated and unstimulated; however, there is no consensus on how sampling method influences oral microbiome metrics. In this study, we analyzed paired saliva samples (unstimulated and stimulated) from 88 individuals, aged 7-18 years. Using 16S rRNA gene sequencing, we investigated the differences in bacterial microbiome composition between sample types and determined how sampling method affects the distribution of taxa associated with untreated dental caries and gingivitis. Our analyses indicated significant differences in microbiome composition between the sample types. Both sampling methods were able to detect significant differences in microbiome composition between healthy subjects and subjects with untreated caries. However, only stimulated saliva revealed a significant association between microbiome diversity and composition in individuals with diagnosed gingivitis. Furthermore, taxa previously associated with dental caries and gingivitis were preferentially enriched in individuals with each respective disease only in stimulated saliva. Our study suggests that stimulated saliva provides a more nuanced readout of microbiome composition and taxa distribution associated with untreated dental caries and gingivitis compared to unstimulated saliva.

[PMID: 37704635 PMCID: PMC10500012 DOI: 10.1038/s41405-023-00170-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2023] [Revised: 08/30/2023] [Accepted: 09/02/2023] [Indexed: 09/15/2023] Open
Abstract
OBJECTIVE This study aimed to evaluate salivary pH changes after consuming three types of milk in children aged 3-5 years. The null hypothesis was that no statistically significant difference would be noted in the salivary pH between high-protein, full-fat, and sweetened milk groups at different time points. MATERIALS AND METHODS This was a double-blind, pilot randomized controlled crossover trial. 30 Children have undergone three experimental sessions with a 1-week washout period. Each child was given 250 mL of one of the following types of milk: high-protein, full-fat, or sweetened milk. The salivary pH was measured at the baseline (t0) after 5 (t1), 10 (t2), 15 (t3), 30 (t4), and 60 (t5) minutes of milk consumption, using a pH saliva indicator strip. RESULTS There is a sharp drop in salivary pH after 5 min of sweetened (P < 0.05) and full-fat milk consumption (p < 0.05). However, the initial drop in the salivary pH was found to remain above the critical level. For the high-protein milk group, salivary pH decreased slightly after 5 min but was similar to that at the baseline (p = 0.573). In the high-protein milk group (p < 0.05), the salivary pH was slightly greater than the baseline value at t5. CONCLUSIONS The study shows an initial suggestion that milk is a non-cariogenic beverage, even when sugar is added. Furthermore, high-protein milk has a protective effect from dental caries.

Abstract
To determine the effects on gingival bleeding, dental biofilm, and salivary flow and pH in patients with gingivitis of using toothpaste with extra-virgin olive oil (EVOO), xylitol, and betaine in comparison to a placebo or commercial toothpaste. This controlled, double blinded, and multicenter randomized clinical trial included patients with gingivitis randomly assigned to one of three groups: test group (EVOO, xylitol, and betaine toothpaste), control group 1 (placebo toothpaste), or control group 2 (commercial toothpaste). Percentage supragingival biofilm and gingival bleeding were evaluated at baseline (T0), 2 months (T2), and 4 months (T4), measuring non-stimulated salivary flow and salivary pH. Comparisons were performed between and within groups. The final study sample comprised 20 in the test group, 21 in control group 1, and 20 in control group 2. In comparison to control group 1, the test group showed significantly greater decreases in gingival bleeding between T4 and T0 (p = 0.02) and in biofilm between T2 and T0 (p = 0.02) and between T4 and T0 (p = 0.01). In the test group, salivary flow significantly increased between T2 and T0 (p = 0.01), while pH alkalization was significantly greater between T4 and T0 versus control group 2 (p = 0.01) and close-to-significantly greater versus control group 1 (p = 0.06). The toothpaste with EVOO, xylitol, and betaine obtained the best outcomes in patients with gingivitis, who showed reductions in gingival bleeding and supragingival biofilm and an increase in pH at 4 months in comparison to a commercial toothpaste.

Alterations of oral microbiota and impact on the gut microbiome in type 1 diabetes mellitus revealed by integrated multi-omic analyses. MICROBIOME 2022; 10:243.

Abstract
BACKGROUND Alterations to the gut microbiome have been linked to multiple chronic diseases. However, the drivers of such changes remain largely unknown. The oral cavity acts as a major route of exposure to exogenous factors including pathogens, and processes therein may affect the communities in the subsequent compartments of the gastrointestinal tract. Here, we perform strain-resolved, integrated meta-genomic, transcriptomic, and proteomic analyses of paired saliva and stool samples collected from 35 individuals from eight families with multiple cases of type 1 diabetes mellitus (T1DM). RESULTS We identified distinct oral microbiota mostly reflecting competition between streptococcal species. More specifically, we found a decreased abundance of the commensal Streptococcus salivarius in the oral cavity of T1DM individuals, which is linked to its apparent competition with the pathobiont Streptococcus mutans. The decrease in S. salivarius in the oral cavity was also associated with its decrease in the gut as well as higher abundances in facultative anaerobes including Enterobacteria. In addition, we found evidence of gut inflammation in T1DM as reflected in the expression profiles of the Enterobacteria as well as in the human gut proteome. Finally, we were able to follow transmitted strain-variants from the oral cavity to the gut at the individual omic levels, highlighting not only the transfer, but also the activity of the transmitted taxa along the gastrointestinal tract. CONCLUSIONS Alterations of the oral microbiome in the context of T1DM impact the microbial communities in the lower gut, in particular through the reduction of "mouth-to-gut" transfer of Streptococcus salivarius. Our results indicate that the observed oral-cavity-driven gut microbiome changes may contribute towards the inflammatory processes involved in T1DM. Through the integration of multi-omic analyses, we resolve strain-variant "mouth-to-gut" transfer in a disease context. Video Abstract.

Abstract
PurposeDental caries is a significant public health issue affecting both the diabetic and nondiabetic populations. However, the problem and associated factors of dental caries among diabetics and nondiabetics patients are not well-known in Ethiopia. This study aims to compare the prevalence of dental caries and associated factors among diabetic and nondiabetic patients at the Outpatient Department of Bichena Primary Hospital in Northwest, Ethiopia.MethodsInstitutional based, comparative cross-sectional study was conducted from October 7 to December 6, 2019, among 200 diabetes and 400 nondiabetic adult patients. A consecutive sampling technique was implemented to recruit study participants. Data were collected by a pretested structured questionnaire and analysis was performed in Statistical Package for Social Science version 20. Bivariable and multivariable logistic regressions were employed and variables with a p-value < 0.05 were declared statistically significant.ResultsA total of 582 patients were involved in the study with a response rate of 97.0%. The prevalence of dental caries was 67.9% [95% confidence interval (CI): 63.2%–72.8%] and 79.6% (95% CI: 74.0%–85.70%) in nondiabetic and diabetic group, respectively. Females gender [adjusted odds ratio (AOR) = 1.79, 95% CI: 1.15–2.77], poor oral hygiene (AOR = 2.95, 95% CI: 1.71–5.11), lack of regular teeth cleaning habits (AOR = 3.26, 95% CI: 2.13–4.97), feeling dry mouth (AOR = 2.31, 95% CI: 1.11–4.81), sugared tea drinking (AOR = 2.00, 95% CI: 1.18–3.38), inadequate oral health knowledge (AOR = 3.51, 95% CI: 2.19–5.62), and khat chewing (AOR = 2.14, 95% CI: 1.24–3.71) were significantly associated factors with high prevalence of dental caries.ConclusionThe prevalence of caries was significantly higher among diabetics than nondiabetics. Oral health education with preventive measures such as improving teeth cleaning practice, reducing sugary foods and drinks intake, and improving oral hygiene practice of patients should be mainstreamed along with diabetic follow-up care.

Impact of hyperglycemia on the expression of GLUT1 during oral carcinogenesis in rats. Mol Biol Rep 2022; 49:8369-8380.

Abstract
BACKGROUND On the background of the epidemiological link between diabetes and oral cancer, the present study aimed to analyze the potential involvement of selected glucose transporters (GLUT1/GLUT3/GLUT4), if any, in such putative association. METHODS AND RESULTS Oral carcinogenesis was induced by 4-nitroquinoline N-oxide in 10 non-diabetic and 10 diabetic rats; 8 non-diabetic and 7 diabetic rats served as controls. Expressions of selected GLUTs at mRNA and protein levels were analyzed in oral tissue (normal/lesion) by quantitative real-time PCR and immunohistochemistry respectively. Premalignant lesions (hyperplasia/dysplasia/carcinoma-in-situ) appeared on tongues of carcinogen-treated animals. Significant increase of GLUT1mRNA level was seen from normal to lesion tongues, along increasing lesion grades (from hyperplasia/mild dysplasia to moderate/severe dysplasia) and in lesions induced under hyperglycemic condition than that induced under normoglycemic one; a similar trend was found in transcript variant-1 of GLUT1, but not in variant-2. GLUT3 and GLUT4 mRNA levels were comparable among lesions irrespective of grades and glycemic status. Concordant to mRNA level, overall expression of GLUT1 protein was higher in tongue lesions in presence of hyperglycemia than in absence of such condition; non-lesion portions of tongues exposed to carcinogen showed a similar trend. Moreover in carcinogen-treated groups, non-lesion and lesion portions of tongues under hyperglycemic condition showed predominantly membranous expression for GLUT1 which was again significantly higher than equivalent portions of tongue under normoglycemic condition. CONCLUSION Hyperglycemia seemed to favor GLUT1 over-expression and membrane localization of the protein during oral carcinogenesis. GLUT1 transcript variant-1 appeared to be more important than variant-2 in disease pathogenesis.

Abstract
A one-year prospective human intervention study was performed to examine the effects of fermented lingonberry juice (FLJ), used as a mouthwash for six months, on salivary parameters. A total of 25 adult participants used 10 mL of FLJ as mouthwash 30 s daily for 6 months in addition to their normal oral homecare routines. Standard oral examinations and gathering of samples were performed at the beginning of the study and after six months and one year. Resting and stimulated saliva secretion rates, resting saliva pH, and stimulated saliva buffering capacity were determined. A questionnaire of participants’ subjective sensations of mouth dryness was also recorded at each timepoint. Fermented lingonberry juice mouthwash had positive effect to all five salivary parameters and were, according to the omnibus test, statistically significant during the study period. Analysis of the subjective dry mouth sensation questionnaires revealed that symptoms of xerostomia decreased due to the use of FLJ. This study revealed that the once-a-day use of FLJ mouthwash had a beneficial, increasing effect on salivary flow rates, buffering capacity, and salivary pH. FLJ thus can be safely used as an adjunctive and beneficial therapy in oral homecare, protecting teeth and oral mucosa, including periodontium, and also relieving dry mouth symptoms.

Abstract
OBJECTIVES This study is aimed at describing changes in salivary flow rate and ionic composition present in the saliva of chronic kidney disease (CKD) patients by assessing the pH, calcium, phosphate, and phosphorus concentrations and comparing them to healthy individuals, along with exploring the influence of hemodialysis on these parameters. METHODS The bibliographical search was performed in nine databases to find all types of studies, including observational clinical studies, without restrictions regarding publication year or language. Two reviewers selected the studies, extracted the data, and assessed the risk of bias using JBI tools. Random-effect meta-analysis was performed with the standardized mean difference (SMD) as effect estimate, at a 95% confidence interval. RESULTS Thirty-three studies were included in the qualitative synthesis and 31 studies were included in the meta-analysis. Chronic kidney disease patients presented lower salivary flow rate (SMD: - 1.73; 95% CI = - 2.14; - 1.31), higher pH (SMD: 1.57; 95% CI = 1.11; 2.03), and higher phosphorus concentration (SMD: 0.86; 95% CI = 0.63; 1.09) in saliva. Concurrently, salivary flow rate and pH presented significant changes after hemodialysis, with higher salivary flow rate (SMD: 0.53; 95% CI = 0.25; 0.81) and lower pH (SMD: - 0.53; 95% CI = - 0.88; - 0.19) in patients on hemodialysis treatment. CONCLUSION Chronic kidney disease patients present reduced salivary flow rate and increased pH and phosphorus concentration in saliva. Hemodialysis can increase the salivary flow rate of these patients.

Correlation of Blood and Salivary pH Levels in Healthy, Gingivitis, and Periodontitis Patients before and after Non-Surgical Periodontal Therapy. Diagnostics (Basel) 2022; 12:diagnostics12010097. [PMID: 35054264 PMCID: PMC8774853 DOI: 10.3390/diagnostics12010097] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2021] [Revised: 12/21/2021] [Accepted: 12/27/2021] [Indexed: 11/17/2022] Open
Abstract
Periodontitis is an infectious illness which leads to the inflammation of protective tissues around the teeth and the continuous loss of alveolar bone and conjunctive tissue. Biomarker analysis in serum and saliva helps in the evaluation of disease progression and activity. It is also established that every inflammatory change along with resultant damage of tissues ends up in altered pH values in the fluids and tissues. Aim: To correlate the connection of pH levels in both blood as well as saliva in healthy, periodontitis, and gingivitis patients. Materials and Methods: The current research involved 145 subjects amidst the age of 20 and 55 years. The subjects were split into three different groups: healthy (Group A), gingivitis (Group B), and finally chronic periodontitis (Group C). The recording of clinical parameters was done by gingival index (GI), probing depth (PD), and plaque index (PI). pH of saliva and blood was analyzed with the help of digital single electrode pH meter. Subjects have gone through scaling and root planning (SRP) coupled with the instructions of oral hygiene. They were recalled post 4 weeks, and saliva and blood samples were gathered for analyzing pH. Results: Clinical parameters GI and PI were statistically important in both group C as well as group B post SRP. A crucial change has been observed in attachment levels (AL) and PD in the case of periodontitis group post SRP. The difference in the salivary pH values were significant between group B vs. C and A vs. C before the treatment because the values for group C were acidic, whereas in groups B and A the pH was alkaline. After the treatment, the values were still significant because the pH has become more alkaline compared to preoperative value in both group B and C. Saliva’s pH levels have demonstrated a statistically significant reduction in group C post SRP. Conclusion: Salivary pH levels and blood evidently became alkaline in the group C patients post SRP and there is a positive correlation between them and the clinical parameters.

Abstract
There is emerging evidence that several oral diseases and conditions can be associated with DM. Dental caries, hyposalivation, fungal diseases and endodontics lesions may represent potential oral complications that can be aggravated by chronic hyperglycemia. Individuals with DM have a low perception of oral diseases which can lead to clinically important oral and systemic complications. This review aims to provide data on the most common oral signs and symptoms related to DM and to explore the mechanisms that might explain associations between DM and oral diseases in order to clarify the risks posed by poor oral health in DM. Since the linkage between oral diseases and DM is part of multifactorial aspects related to chronic hyperglycemic status and several common conditions affecting the whole body, both require rigorous self-control from patients and attention from medical and dental professionals.

AlTuraiki AM, Jaemal HM, Alamer AA, Alghwainem AA, Althabit TA, Alamri A, Nazir MA. Oral Health and Patterns of Dental Visits Among Diabetic Patients in the Eastern Province of Saudi Arabia. Clin Cosmet Investig Dent 2021; 13:513-520. [PMID: 34887684 PMCID: PMC8653708 DOI: 10.2147/ccide.s340579] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2021] [Accepted: 11/24/2021] [Indexed: 12/03/2022] Open
Abstract
Purpose Diabetes is a big public health threat in Saudi Arabia. However, there is limited evidence about dental problems, oral hygiene practices, and dental visits among diabetic patients. The study aimed to evaluate self-perceived oral health status and patterns of dental attendance among diabetic patients in the Eastern province of Saudi Arabia. Methodology This cross-sectional study included 486 diabetic patients (mean age 50.14±13.59 years) registered with the Saudi Diabetes Society, Saudi Arabia (October–November 2020). The World Health Organization’s oral health questionnaire for adults was administered to collect information about oral health status, oral hygiene practices, and dental attendance, in addition to sociodemographic data. Descriptive and analytical statistics were performed. Results Most participants (66.3%) reported having dental pain or discomfort during the last year. Bad breath (60.50%), tooth cavities (55.10%), difficulty in biting hard food (55.10%), tooth sensitivity (53.30%), and bleeding gums (52.90%) were common oral problems among participants. More than half the sample (55.1%) reported visiting the dental office during the last year. However, pain or trouble with teeth, gums or mouth was the most common (40.5%) reason for the last dental visit. Only 7.8% of participants visited the dentist for a routine dental check-up. Multiple logistic regression analysis showed that Saudi nationality (AOR 2.68, P 0.008), family history of diabetes (AOR 1.88, P 0.022), and having pain during the last year (AOR 4.01, P <0.001) were the significant factors associated with the last dental visit due to pain. Conclusion This sample of participants demonstrated a high prevalence of dental problems. Few participants performed routine dental visits and most visits were due to pain. Saudis and patients with family history of diabetes and dental pain were more likely to perform pain related dental visits. Multidisciplinary efforts are needed to develop and implement preventive educational and clinical care models for positive oral and general health outcomes.

Abstract
Abstrakt
Background
Diabetes and periodontitis belong to the group of civilizational diseases, which are not associated with any specific bacterial or viral infection but with the rapid development of civilization and technological advances that affect comfort and quality of life. Civilizational diseases occur in highly developed and developing societies. Glycosylated hemoglobin A1c (HbA1c) is one of the standard indicators for the assessment of metabolic compensation in diabetes that reflects the risk of disease complications. One of the significant complications of diabetes that manifests in the oral cavity is gingival and periodontal inflammation, which is directly related to increased insulin resistance and worsened diabetes compensation. Factors influencing inflammation are the patient’s age, directly linked with fine motor skills when it comes to cleaning teeth, and patients’ awareness related to cause-and-effect relationship between dental hygiene, gingival and periodontal inflammation, and HbA1c testing during routine check-ups.
Objectives
To compare the relationship between gingival inflammation and metabolic compensation (HbA1c levels), depending on the patient’s age.
Materials and methods
The study involved 100 patients (50 adolescents and 50 adults, 42 M; 58 F) with type 1 diabetes. The study group was divided according to sex and age into 19 male adolescent patients (10–18 years old; mean age 15.5) and 23 male adult patients (19–45 years old; mean age 27.1). The mean duration of diabetes was 7 years in the group of adolescents and 11 years in the group of adults. The HbA1c levels and gingival index (GI) were measured in all patients. The obtained results were statistically analyzed.
Results
By comparing the study groups, higher HbA1c values were reported in the group of adolescents. HbA1c has been shown to correlate with the GI in adolescents and adults. Despite poorer compensation for diabetes (higher HbA1c), GI values were similar in adolescents and adults.

Abstract
Early detection is a key factor in patient fate. Currently, multiple biomolecules have been recognized as biomarkers. Nevertheless, their identification is only the starting line on the way to their implementation in disease diagnosis. Although blood is the biofluid par excellence for the quantification of biomarkers, its extraction is uncomfortable and painful for many patients. In this sense, there is a gap in which saliva emerges as a non-invasive and valuable source of information, as it contains many of the biomarkers found in blood. Recent technological advances have made it possible to detect and quantify biomarkers in saliva samples. However, there are opportunity areas in terms of cost and complexity, which could be solved using simpler methodologies such as those based on enzymes. Many reviews have focused on presenting the state-of-the-art in identifying biomarkers in saliva samples. However, just a few of them provide critical analysis of technical elements for biomarker quantification in enzymatic methods for large-scale clinical applications. Thus, this review proposes enzymatic assays as a cost-effective alternative to overcome the limitations of current methods for the quantification of biomarkers in saliva, highlighting the technical and operational considerations necessary for sampling, method development, optimization, and validation.

Abstract
This article aims to narrate the various oral complications in individuals suffering from diabetes mellitus. Google search for "diabetes mellitus and oral complications" was done. The search was also carried out for "diabetes mellitus" and its oral complications individually. Diabetes mellitus is a chronic metabolic disorder that is a global epidemic and a common cause of morbidity and mortality in the world today. Currently, there are about 422 million cases of diabetes mellitus worldwide. Diabetic patients can develop different complications in the body such as retinopathy, neuropathy, nephropathy, cardiovascular disease. Complications in the oral cavity have been observed in individuals suffering from diabetes mellitus. A study noted that more than 90% of diabetic patients suffered from oral complications. Another research has shown a greater prevalence of oral mucosal disorders in patients with diabetes mellitus than non-diabetic population: 45-88% in patients with type 2 diabetes compared to 38.3-45% in non-diabetic subjects and 44.7% in type 1 diabetic individuals compared to 25% in the non-diabetic population. Oral complications in people with diabetes are periodontal disease, dental caries, oral infections, salivary dysfunction, taste dysfunction, delayed wound healing, tongue abnormalities, halitosis, and lichen planus. The high glucose level in saliva, poor neutrophil function, neuropathy, and small vessel damage contribute to oral complications in individuals with uncontrolled diabetes. Good oral health is imperative for healthy living. Oral complications cause deterioration to the quality of life in diabetic patients. Complications like periodontal disease having a bidirectional relationship with diabetes mellitus even contribute to increased blood glucose levels in people with diabetes. This article intends to promote awareness regarding the oral health of diabetics and to stress the importance of maintaining proper oral hygiene, taking preventive measures, early detection, and appropriate management of oral complications of these patients through a multidisciplinary approach.

Abstract
Following a single blind, cross-over and non-randomized design we investigated the effect of 7-day use of chlorhexidine (CHX) mouthwash on the salivary microbiome as well as several saliva and plasma biomarkers in 36 healthy individuals. They rinsed their mouth (for 1 min) twice a day for seven days with a placebo mouthwash and then repeated this protocol with CHX mouthwash for a further seven days. Saliva and blood samples were taken at the end of each treatment to analyse the abundance and diversity of oral bacteria, and pH, lactate, glucose, nitrate and nitrite concentrations. CHX significantly increased the abundance of Firmicutes and Proteobacteria, and reduced the content of Bacteroidetes, TM7, SR1 and Fusobacteria. This shift was associated with a significant decrease in saliva pH and buffering capacity, accompanied by an increase in saliva lactate and glucose levels. Lower saliva and plasma nitrite concentrations were found after using CHX, followed by a trend of increased systolic blood pressure. Overall, this study demonstrates that mouthwash containing CHX is associated with a major shift in the salivary microbiome, leading to more acidic conditions and lower nitrite availability in healthy individuals.

Abstract
BACKGROUND AND OBJECTIVES Diabetes mellitus has increased rapidly throughout the world. The objectives of our study were to assess the knowledge and awareness about oral manifestations of diabetes, among type 2 diabetes mellitus patients, their risk for developing oral diseases due to complications associated with diabetes mellitus, and at same time, to perform an oral examination to detect these oral symptoms, if present any, along with the recording of Decayed Missing Filled Teeth Index (DMFT) and Community Periodontal Index (CPI) index. METHODOLOGY Structured questionnaires consisting of 12 different statements on the knowledge base of oral manifestations of diabetes mellitus were distributed to 447 Type 2 diabetes mellitus patients. Following this oral examination, brushing and dental visit history were noted, and CPI index and DMFT indices were recorded in all the patients. RESULTS Results showed that the knowledge about oral manifestations of diabetes mellitus was poor with a mean value of 4.92 out of a possible score of 12. Among the study subjects, the average score of men was 4.42 while that of females, was 5.41. These scores, when subjected to statistical analysis, were highly significant. (P value- 0.005) Subjects also showed significantly high DMFT (P value <0.001) and CPI scores (P value- 0.270). CONCLUSION Our study concluded that there is a significant lack of knowledge about oral manifestations of diabetes mellitus among patients and hence steps have to be taken to increase their awareness through various outreach programs. All health professionals need to work together for promoting better oral health so that oral complications of diabetes can be brought under control.

Abstract
We estimated effects of diabetes mellitus and metabolic control on long-term change in coronal caries and restorative status using 11-year-follow-up data from the population-based Study of Health in Pomerania. Data of 3731 participants with baseline and 5- and 11-year follow-up information were included. Diabetes was defined via self-reported physician´s diagnosis or intake of glucose-lowering drugs or hemoglobin A1c (HbA1c) ≥6.5% or fasting blood glucose levels ≥11.1 mmol/l. The diabetes status was defined as no diabetes (HbA1c < 6.5% or non-fasting blood glucose <11.1 mmol/l), subjects with known or undetected diabetes mellitus and HbA1c ≤ 7% (well-controlled diabetes), and subjects with known or undetected diabetes mellitus and HbA1c > 7% (poorly-controlled diabetes). The caries status was clinically assessed using the half-mouth method and the Decayed Missing Filled Surfaces (DMFS) index and its component scores were determined. Covariate-adjusted linear mixed models were evaluated. Rates in change in DMFS were significantly higher in subjects with poorly-controlled diabetes compared to subjects without diabetes. Subjects with poorly- and well-controlled diabetes had significantly higher rates in change in Missing Surfaces (MS) compared to subjects without diabetes. For the DFS, rates in change were significantly lower for subjects with well-controlled diabetes and higher for subjects with poorly-controlled diabetes as compared to subjects without diabetes. Concordantly, all rates in change increased proportional to HbA1c levels. Effects were even more pronounced in subjects with diabetes duration of ≥5 years. Subjects with poorly-controlled diabetes are at higher risk for caries progression compared to subjects without diabetes, especially in case of longer disease duration.

Abstract
Many periodontal patients may need orthodontic treatment. Alterations in oral environment particularly the reduction of pH in periodontal patients could affect metal ion release from orthodontic appliances. However, there is no study on metal ion release in periodontal patients. The aim of this preliminary study was to comparatively evaluate, for the first time, salivary levels of nickel and chromium in periodontal patients (versus healthy controls) under orthodontic treatment for 2 months. In this in vivo study, 40 subjects were evaluated. Patient selection and standardization of orthodontic treatment protocols were prospectively designed and performed. Two groups of n = 20 each (control: healthy orthodontic patients, cohort: orthodontic patients with periodontitis) underwent similar protocols of fixed orthodontic treatment for 2 months. After 2 months, salivary nickel and chromium concentrations of the case and cohort groups were measured using inductively coupled plasma mass spectrometry (ICP-MS). The values were compared between the two groups using t test. There were 10 men and 10 women in each group. The mean age of patients was 34.6 ± 3.6 years old. The salivary level of nickel was 338.2 ± 235.5 ng/ml and 182.8 ± 116.5 ng/ml in the cohort and control groups, respectively (P = 0.0118). The salivary level of chromium was 7.4 ± 3.15 ng/ml in the cohort and 6.35 ± 2.39 ng/ml in the control group (P = 0.2214). Salivary level of nickel might be considerably higher in periodontal patients undergoing 2 months of orthodontic treatment compared to orthodontic patients with healthy gingivae.

Abstract
OBJECTIVE This study aimed to provide the correlation of circadian rhythms of night shift workers with blood glucose levels, saliva, and dental caries. MATERIALS AND METHODS This study was conducted on night shift and nonshift workers to measure fasting blood glucose (FBG), 2-hour postprandial blood glucose (2-PP BG), saliva flow rate, pH saliva, and caries with the decay-missing-filled total (DMF-T) index. Data analysis was done using independent t-test and correlation test with Pearson correlation. RESULTS There were significant differences in night shift and nonshift workers in FBG (p = 0.000), 2-PP BG (p = 0.000), flow rate saliva (p = 0.000), and DMF-T index (p = 0.001). Correlation test showed positive correlation between FBG and pH saliva (r = 0.42, p = 0.029) and DMF-T index (r = 0.521, p = 0.005) of night shift workers. The 2-PP BG also showed positive correlation with pH saliva (r = 0.493, p = 0.009) and DMF-T index (r = 0.743, p = 0.000). The DMF-T index showed negative correlation with flow rate saliva (r = -0.398, p = 0.04). In the nonshift workers, correlation test showed a correlation between FBG and DMF-T index (r = 0.384, p = 0.048). The DMF-T index showed correlation with flow rate saliva (r = 0.6, p = 0.001). CONCLUSION There is a circadian rhythm correlation between night shift workers to blood glucose levels, flow rate saliva, pH saliva, and dental caries.

Abstract
pH-sensing materials and configurations are rapidly evolving toward exciting new applications, especially those in biomedical applications. In this review, we highlight rapid progress in electrochemical pH sensors over the past decade (2008-2018) with an emphasis on key considerations, such as materials selection, system configurations, and testing protocols. In addition to recent progress in optical pH sensors, our main focus in this review is on electromechanical pH sensors due to their significant advances, especially in biomedical applications. We summarize developments of electrochemical pH sensors that by virtue of their optimized material chemistries (from metal oxides to polymers) and geometrical features (from thin films to quantum dots) enable their adoption in biomedical applications. We further present an overview of necessary sensing standards and protocols. Standards ensure the establishment of consistent protocols, facilitating collective understanding of results and building on the current state. Furthermore, they enable objective benchmarking of various pH-sensing reports, materials, and systems, which is critical for the overall progression and development of the field. Additionally, we list critical issues in recent literary reporting and suggest various methods for objective benchmarking. pH regulation in the human body and state-of-the-art pH sensors (from ex vivo to in vivo) are compared for suitability in biomedical applications. We conclude our review by (i) identifying challenges that need to be overcome in electrochemical pH sensing and (ii) providing an outlook on future research along with insights, in which the integration of various pH sensors with advanced electronics can provide a new platform for the development of novel technologies for disease diagnostics and prevention.

Abstract
Lactoperoxidase (LPO) present in saliva are an important element of the nonspecific immune response involved in maintaining oral health. The main role of this enzyme is to oxidize salivary thiocyanate ions (SCN-) in the presence of hydrogen peroxide (H₂O₂) to products that exhibit antimicrobial activity. LPO derived from bovine milk has found an application in food, cosmetics, and medical industries due to its structural and functional similarity to the human enzyme. Oral hygiene products enriched with the LPO system constitute an alternative to the classic fluoride caries prophylaxis. This review describes the physiological role of human salivary lactoperoxidase and compares the results of clinical trials and in vitro studies of LPO alone and complex dentifrices enriched with bovine LPO. The role of reactivators and inhibitors of LPO is discussed together with the possibility of using nanoparticles to increase the stabilization and activity of this enzyme.

Open Access Maced J Med Sci 2018; 6:1545-1553. [PMID: 30159091 PMCID: PMC6108795 DOI: 10.3889/oamjms.2018.294] [Citation(s) in RCA: 55] [Impact Index Per Article: 9.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2018] [Revised: 06/27/2018] [Accepted: 07/03/2018] [Indexed: 12/14/2022] Open
Abstract
BACKGROUND Diabetes mellitus (DM), chronic disease, is a public health problem that affects 8.5% adult population worldwide. The number of adults with DM has risen sharply from 108 million in 1980 to 422 million in 2014. In 2012, 1.5 million individuals died because of DM and an additional 2.2 million deaths occurred because of high blood glucose level resulting in cardiovascular and other systemic diseases. DM brings huge economic loss to patients, their families, and healthcare systems. Globally, the cost of DM was US$1•31 trillion in 2015. AIM This review article utilised the prevalence data of diabetes mellitus from the World Health Organization and International Diabetes Federation to provide a comprehensive picture of the disease in different parts of the world. METHODS Electronic databases such as Google Scholar, Medline via PubMed, Scopus, and Web of Science were used to search the literature. The library resources of Imam Abdulrahman Bin Faisal University, Dammam, Saudi Arabia were used to retrieve studies on the topics of the present review. RESULTS Systemic complications of DM include heart attack, kidney disease, limb loss, blindness, and peripheral nerve damage. More than 90% of diabetic patients were found to have oral manifestations. It is known that DM severely damages oral tissues causing periodontal disease, tooth loss, xerostomia, caries, burning mouth disorder, taste and salivary gland dysfunction, delayed wound healing, lichen planus, geographic tongue, and candidiasis. The evidence is mounting about a strong bidirectional relationship between DM and periodontal disease. Unfortunately, many diabetic patients are unaware of the association between DM and oral health, and only a small percentage of them visit the dentist for routine dental check-ups. Changes in lifestyles (control of blood glucose levels and self-care practices), regular dental check-ups with emphasis on periodontal assessment, and reinforcement of oral health instructions can effectively prevent oral complications of DM. Scaling and root planning are effective in improving glycemic control among diabetic patients. CONCLUSION Dental professionals should be part of the multidisciplinary team that helps individuals with diabetes.

Relationship between Physicochemical Properties of Saliva and Dental Caries and Periodontal Status among Female Teachers Living in Central Iran. J Int Soc Prev Community Dent 2018; 8:48-55. [PMID: 29629329 PMCID: PMC5853042 DOI: 10.4103/jispcd.jispcd_391_17] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2017] [Accepted: 12/18/2017] [Indexed: 11/17/2022] Open
Abstract
Objectives: There are inconsistent data about the association between saliva properties, dental caries, and periodontal status. In this study, we tried to examine the association between dental caries and periodontal status with salivary viscosity, flow rate, pH, and buffering capacity in adults. Methods: In the present cross-sectional study, 450 female teachers were randomly selected from schools located in Yazd, Iran. Oral examinations were conducted, and unstimulated saliva samples were collected. Salivary viscosity, flow rate, pH, and buffering capacity were assessed. The salivary physicochemical properties were compared among teachers with different types of oral health. Analyses were done using the Statistical Package for the Social Sciences version 16. Results: In total, 431 female teachers aged 40.45 ± 8.18 years were included in the study. Salivary flow rate, buffering capacity, pH, and viscosity, community periodontal index status were not significantly different in participants with and without tooth caries. There was a reverse linear association between salivary pH and flow rate with the decayed, missed, and filled teeth index (P < 0.05). The saliva buffering capacity was not significantly related to dental properties. Those with bleeding on probing had lower salivary pH, and buffering capacity compared to those with healthy gum. However, the salivary resting flow rate was not different in participants with bleeding on probing and healthy participants. Conclusion: Based on our results, saliva properties might be important predictors in oral health status. This means that any change in saliva combination might affect periodontal and dental diseases. Future prospective studies are recommended to confirm these results.

Abstract
Oral administration of drugs presents important limitations, which are frequently not granted the importance that they really have. For instance, hepatic metabolism means an important drug loss, while some patients have their ability to swell highly compromised (i.e. unconsciousness, cancer…). Sublingual placement of an accurate Pharmaceutical Dosage Form is an attractive alternative. This work explores the use of the β-chitosan membranes, from marine industry residues, composed with marine sediments for dual sublingual drug delivery. As proof of concept, the membranes were loaded with a hydrophilic (gentamicin) and a hydrophobic (dexamethasone) drug. The physico-chemical and morphological characterization indicated the successful incorporated of diatomaceous earth within the chitosan membranes. Drug delivery studies showed the potential of all formulations for the immediate release of hydrophilic drugs, while diatomaceous earth improved the loading and release of the hydrophobic drug. These results highlight the interest of the herein developed membranes for dual drug delivery.

Abstract
Background: Diabetes mellitus is a metabolic disease leading to abnormal fat, carbohydrate and protein metabolism. Reduced salivary flow rate caused by hyperglycemia is characteristic mainly for periods of poor metabolic control of diabetes, thereby facilitating the growth of aciduric bacteria and caries-lesion development. The objective of our study was to evaluate the effects of diabetes mellitus on dental caries micro-organisms responsible for caries. Materials and Methods: This study was carried out on 60 subjects consisting of 2 groups. The Group A (study group) consisted of 30 subjects with diabetes mellitus and dental caries, and the Group B (control group) consisted of 30 subjects with dental caries but no systemic disease. DFS/dfs index in all subjects was evaluated and compared. Unstimulated salivary flow was collected and levels of Streptococcus mutans were analyzed. Results: It was found that the fasting blood sugar in Group A subjects because of which there was increased streptococcus mutans count and hence high caries index as compared to that of Group B. Conclusion: From our study, we could conclude that with increased age, blood sugar levels, DMFT values, dental caries increases in diabetics than in normal (control) subjects and therefore relationship does exist between diabetis mellitus, oral microbiota and dental caries.

Abstract
AIM To evaluate the antimicrobial activity of hydroalcoholic extracts of pomegranate (Punica granatum L.) peel and juice, against the microorganisms considered the main etiologic agents of dental caries. METHODS The values of the minimum inhibitory concentration (MIC) and the minimum bactericidal concentration (MBC) were determined against Streptococcus mutans Clarke ATCC® 25175™ strain and Rothia dentocariosa clinical isolate. RESULTS Peel extracts inhibit effectively the growth and survival of S. mutans ATCC 25175 strain and R. dentocariosa clinical isolate with MIC and MBC values of 10 μg/μl and 15 μg/μl, respectively. Furthermore, the pomegranate juice extract showed high inhibitory activity against S. mutans ATCC 25175 strain with a MIC value of 25 μg/μl and a MBC value of 40 μg/μl, whereas, against R. dentocariosa, it has displayed a moderate inhibitory activity, with MIC and MBC values of 20 μg/μl and 140 μg/μl, respectively. CONCLUSIONS In vitro microbiological tests demonstrate that the hydroalcoholic extracts of pomegranate juice and peel are able to contrast the main cariogenic bacteria involved in tooth decay. Although being preliminary data, our results suggest that pomegranate polyphenolic compounds could represent a good adjuvant for the prevention and treatment of dental caries.

Abstract
Chewing gums may be particularly effective means for delivering and maintaining bioactive molecules, included in the gum formulation, able to have an anti-cariogenic effect. The purposes of this study were: to develop novel chewing gums containing quercetin (Qt); to evaluate their release using in vivo trial; finally, to test their in vivo antibacterial effect against oral Streptococcus mutans strains. A preliminary study was performed to produce new gums, enriched with the polyphenol quercetin. Then, a first in vivo experimental study was assessed to test the percentages of Qt released in the saliva of young volunteers. Moreover, a second clinical trial was performed to analyze the antibacterial capability of these enriched chewing gums against S. mutans strains after 14 days of daily consumption. The release analysis showed that a more effective release of Qt occurs in the first minutes of chewing, and it does not change saliva pH values. Moreover, Qt included in gums demonstrates an effective antibacterial activity, showing a reduction of the concentration of S. mutans strains in saliva samples, especially after 7 days. Qt included in experimental chewing gums could be efficiently released into the oral cavity and could promote an effective anti-caries concentration in volunteer's saliva, without changing salivary pH values.

Abstract
INTRODUCTION In oral diagnostics there is a great challenge to determine biomarkers for screening and evaluating the disease activity. Biomarkers can also serve as a useful tool to measure the efficacy of the therapy. AIM To evaluate and compare the levels of salivary calcium, phosphorous, alkaline phosphatase and pH levels in periodontally healthy subjects and patients with gingivitis and periodontitis. MATERIALS AND METHODS The present study consisted of 150 subjects aged between 20-45 years who were divided into three groups; periodontally healthy, gingivitis and chronic periodontitis. Prior to the clinical examination the demographic details, relevant information of the subject, gingival index, plaque index, Oral Hygiene Index (OHI) and pH were recorded. Biochemical assay of saliva i.e., inorganic calcium, phosphorous and alkaline phosphatase were estimated by colorimetric method. ANOVA and Tukey's test were applied for statistical analysis. RESULTS The mean levels of biomarkers studied were; inorganic calcium (12.55μg/dl), phosphorous (14.50μg/dl), alkaline phosphatase (49.62μg/dl) and pH (11.65). There was a gradual increase in these levels as the condition progressed from health to gingivitis or periodontitis which was statistically significant at p<0.001. CONCLUSION Based on these results, it can be concluded that, the biomarkers like salivary calcium, phosphorous, alkaline phosphatase and pH can be considered for evaluating the diagnosis and prognosis of periodontal tissues in disease and health.

Abstract
Objectives: Diabetes mellitus (DM) is a common chronic metabolic disorder which affects millions of people. At present, India has the highest incidence of diabetes worldwide. Several oral lesions and conditions are associated with diabetes. However, there is a lack of consensus among researchers regarding the relationship between DM and dental caries. Hence, the present study was carried out to assess the dental caries prevalence among type II diabetic and nondiabetic adults attending a hospital in Ahmedabad city. Materials and Methods: A hospital-based cross-sectional study was conducted. One hundred and twenty diabetics individuals attending the diabetic Outpatient Department (OPD) and age and sex-matched 120 nondiabetic individuals from general OPD were included in the study. The data were gathered through semi-close-ended questionnaire and clinical examination. Dental caries was assessed by using the World Health Organization's 2013 proforma. Data was analyzed by applying Student's independent t-test or one-way analysis of variance. Results: Dental caries prevalence among the diabetic group was 73.33% and 33.33% among the nondiabetic group. Dental caries prevalence and mean dental caries was significantly higher among uncontrolled diabetic individuals than that among controlled diabetic individuals. Duration of the disease and dental caries prevalence did not show any significant difference. Conclusion: Dental caries prevalence was significantly high among diabetic individuals compared with nondiabetic individuals. Close collaboration between the patients, healthcare units, and oral health professionals could be a way of improving diabetic patients' general and oral health.
