Sustained Release of Salicylic Acid for Halting Peri-Implantitis Progression in Healthy and Hyperglycemic Systemic Conditions: A Gottingen Minipig Model. ACS Biomater Sci Eng 2024; 10:3097-3107. [PMID: 38591966 PMCID: PMC11094686 DOI: 10.1021/acsbiomaterials.4c00161] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2024] [Revised: 03/20/2024] [Accepted: 03/21/2024] [Indexed: 04/10/2024]
Abstract
To develop a peri-implantitis model in a Gottingen minipig and evaluate the effect of local application of salicylic acid poly(anhydride-ester) (SAPAE) on peri-implantitis progression in healthy, metabolic syndrome (MS), and type-2 diabetes mellitus (T2DM) subjects. Eighteen animals were allocated to three groups: (i) control, (ii) MS (diet for obesity induction), and (iii) T2DM (diet plus streptozotocin for T2DM induction). Maxillary and mandible premolars and first molar were extracted. After 3 months of healing, four implants per side were placed in both jaws of each animal. After 2 months, peri-implantitis was induced by plaque formation using silk ligatures. SAPAE polymer was mixed with mineral oil (3.75 mg/μL) and topically applied biweekly for up to 60 days to halt peri-implantitis progression. Periodontal probing was used to assess pocket depth over time, followed by histomorphologic analysis of harvested samples. The adopted protocol resulted in the onset of peri-implantitis, with healthy minipigs taking twice as long to reach the same level of probing depth relative to MS and T2DM subjects (∼3.0 mm), irrespective of jaw. In a qualitative analysis, SAPAE therapy revealed decreased levels of inflammation in the normoglycemic, MS, and T2DM groups. SAPAE application around implants significantly reduced the progression of peri-implantitis after ∼15 days of therapy, with ∼30% lower probing depth for all systemic conditions and similar rates of probing depth increase per week between the control and SAPAE groups. MS and T2DM conditions presented a faster progression of the peri-implant pocket depth. SAPAE treatment reduced peri-implantitis progression in healthy, MS, and T2DM groups.

Evaluating the effect of mechanical debridement with adjunctive antimicrobial photodynamic therapy in comparison with mechanical debridement alone on the peri-implant parameters in type 2 diabetic mellitus patients with peri-implantitis: a systematic review and meta-analysis. BMC Oral Health 2023; 23:751. [PMID: 37828479 PMCID: PMC10571232 DOI: 10.1186/s12903-023-03337-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2023] [Accepted: 08/19/2023] [Indexed: 10/14/2023] Open
Abstract
BACKGROUND Type 2 diabetes mellitus (T2DM) is a major risk factor for localized diseases such as peri-implantitis that may affect ideal implant treatment. This study was aimed to evaluate the effect of mechanical debridement (MD) + antimicrobial photodynamic therapy (a-PDT) in patients with peri-implantitis who have T2DM in terms of bleeding on probing (BOP) and probing depth (PD) as primary outcomes and plaque index (PI) and crestal bone loss (CBL) as secondary outcomes. METHODS Publications compared outcomes between MD + aPDT and MD alone in T2DM patients with peri-implantitis, containing more than 3-month follow-up duration, were involved in the systematic review and meta-analysis. Literature until July 2023 using MEDLINE (through PubMed), Scopus, Cochrane Library, Embase, Web of Science, and Google Scholar were collected. RESULTS Two randomized controlled trials (RCTs, 88 individuals) and one controlled clinical trial (CCT, 67 individuals) with follow-up periods ranged from 3 to 12 months were recruited. All studies used diode laser with wavelengths ranged from 660 to 810 nm. The results demonstrated that the MD + aPDT group showed significant benefits for BOP reduction after 6 months (SMD = -2.15, 95% CI: -3.78 to -0.51, p = 0.01). However, a great amount of heterogeneity was observed (I2 = 91.52%, p < 0.001). Moreover, there was a significant difference between MD + aPDT and MD alone groups in CBL (SMD = -0.69, 95% CI: -1.07 to -0.30, p < 0.001). In addition, homogeneity assumption was satisfied (I2 = 22.49%, p = 0.28). Significant differences in PD and PI reduction were not found except for PI reduction after 3 months (SMD = -0.79, 95% CI: -1.24 to -0.33, p < 0.001. Also, no heterogeneity was observed (I2 = 0.00%, p = 0.47). CONCLUSION Given that high heterogeneity in BOP and PD outcome was found in this systematic review, future long-term CTs with MD + aPDT should be examined to arrive at a firm conclusion.

Abstract
Accumulating evidences strongly support the correlations between the compositions of gut microbiome and therapeutic effects on Type 2 diabetes (T2D). Notably, gut microbes such as Akkermansia muciniphila are found able to regulate microecological balance and alleviate dysmetabolism of mice bearing T2D. In order to search out similarly functional bacteria, bacteriophage MS2 with a good specificity to bacteria carrying fertility (F) factor were used to treat T2D mice. Based on multi-omics analysis of microbiome and global metabolism of mice, we observed that gavage of bacteriophage MS2 and metformin led to a significant increase in the abundance of Corynebacterium glutamicum and A. muciniphila, respectively. Consequently, the gut microbiota were remodeled, leading to variations in metabolites and a substantial increase in short-chain fatty acids (SCFAs). In which, the amount of acetate, propionate, and butyrate presented negative correlations to that of proinflammatory cytokines, which was beneficial to repairing the intestinal barriers and improving their functions. Moreover, main short fatty acid (SCFA) producers exhibited positive interactions, further facilitating the restoration of gut eubiosis. These findings revealed that C. glutamicum and its metabolites may be potential dietary supplements for the treatment of T2D. Moreover, our research contributes to a novel understanding of the underlying mechanism by which functional foods exert their anti-diabetic effects.

Abstract
In order to find new α-glucosidase inhibitors with high efficiency and low toxicity, novel chromone-based benzohydrazide derivatives 6a-6s were synthesized and characterized through 1H NMR, 13C NMR, and HRMS. All the new synthesized compounds were tested for inhibitory activities against α-glucosidase. Compounds 6a-6s with IC50 values ranging from 4.51 ± 0.09 to 27.21 ± 0.83 μM, showed a potential α-glucosidase inhibitory activity as compared to the positive control (acarbose: IC50 = 790.40 ± 0.91 μM). Compound 6i exhibited the highest α-glucosidase inhibitory activity with an IC50 value of 4.51 ± 0.09 μM. Theinteractionbetween α-glucosidase and 6i was further confirmed by enzyme kinetic, fluorescence quenching, circular dichroism, and molecular docking study. In vivo experiment showed that 6i could suppress the rise of blood glucose levels after sucrose loading. The cytotoxicity result indicated that 6i exhibited low cytotoxicity in vitro.

Abstract
BACKGROUND Oral lichen planus (OLP) is a chronic disease commonly detected in older aged patients with female predominance. Treatment of OLP in diabetic and hypertensive patients usually shows some difficulties which require a more safe and effective treatment modality such as Photodynamic therapy (PDT). The current study aims to evaluate the role of PDT in treating OLP in diabetic and hypertensive patients. METHODS We evaluated the role of PDT in treating erosive OLP of type 2 diabetic and hypertensive patients. The following parameters were evaluated for each case at the time zero, after2 weeks, and 4 weeks of the study: subjective responses, objective responses, and the size of the lesion. RESULTS Our study included 9 diabetic and 7hypertensive patients with an age range of 30:60 years old. There were statistically significant differences between the diabetic and hypertensive patients in the objective response, area of ulceration, and the area of erythema at the end of the 4th week of the study (p<0.05). CONCLUSION PDT is an effective treatment modality for diabetic and hypertensive patients with no side effects or patient discomfort.

Bullied Because of Their Teeth: Evidence from a Longitudinal Study on the Impact of Oral Health on Bullying Victimization among Australian Indigenous Children. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19094995. [PMID: 35564388 PMCID: PMC9101169 DOI: 10.3390/ijerph19094995] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/22/2022] [Revised: 04/07/2022] [Accepted: 04/15/2022] [Indexed: 02/01/2023]
Abstract
Making life better for Indigenous peoples is a global priority. Although bullying and oral health have always been a topic of concern, there is limited information regarding the impact of this problem on the general population, with no evidence in this regard among the Australian Indigenous population. Thus, we aimed to quantify the relationship between bullying victimization and oral health problems by remoteness among 766 Australian Indigenous children aged between 10−15-years using data from the LSIC study. Bivariate and multilevel mixed-effect logistic regression analyses were employed. Findings indicated children self-reported bullying more than parents reported their children were being bullied (44% vs. 33.6%), with a higher percentage from rural/remote areas than urban areas. Parents reported that oral health problems increased the probability (OR 2.20, p < 0.05) of being bullied, in Indigenous children living in urban areas. Racial discrimination, lower level of parental education and poor child oral hygiene increase the risk of bullying victimization. Parental happiness with life and a safe community were associated with a lower risk of bullying. Dental problems are linked with Australian Indigenous children experiencing bullying victimization. Cultural resilience and eliminating discrimination may be two modifiable paths to ameliorating health issues associated with bullying in the Australian Indigenous community.

Abstract
Background: The integration of medical care into the dental setting has been shown to facilitate the closure of care gaps among patients with unmet needs. However, little is known about whether program effectiveness varies depending on whether the care gap is related to preventive care or disease management. Materials and Methods: We used a matched cohort study design to compare closure of care gaps between patients aged 65+ who received care at a Kaiser Permanente Northwest (KPNW) Medical–Dental Integration (MDI) clinic or a non-MDI dental clinic between June 1, 2018, and December 31, 2019. The KPNW MDI program focuses on closing 12 preventive (e.g., flu vaccines) and 11 disease management care gaps (e.g., HbA1c testing) within the dental setting. Using the multivariable logistic regression, we separately analyzed care gap closure rates (yes vs. no) for patients who were overdue for: (1) preventive services only (n = 1,611), (2) disease management services only (n = 538), or (3) both types of services (n = 429), analyzing closure of each care gap type separately. All data were obtained through the electronic health record of KPNW. Results: The MDI patients had significantly higher odds of closing preventive care gaps (OR = 1.51, 95% CI = 1.30–1.75) and disease management care gaps (OR = 1.65, 95% CI = 1.27–2.15) than the non-MDI patients when they only had care gaps of one type or the other. However, no significant association was found between MDI and care gap closure when patients were overdue for both care gap types. Conclusions: Patients with care gaps related to either preventive care or disease management who received dental care in an MDI clinic had higher odds of closing these care gaps, but we found no evidence that MDI was helpful for those with both types of care gaps. Practical Implications: MDI may be an effective model for facilitating the delivery of preventive and disease management services, mainly when patients are overdue for one type of these services. Future research should examine the impact of MDI on long-term health outcomes.

Abstract
Background This 6-months randomized controlled clinical trial aimed to assess the efficacy of indocyanine green mediated photodynamic therapy (ICG-PDT) as an adjunct to peri‑implant manual debridement (PIMD) versus PIMD alone among Diabetes Mellitus (DM) patients in the treatment of peri‑implantitis. Methods A total of 48 DM patients having 64 implants were treated with either ICG-PDT + PIMD (n = 35 implants) or PIMD alone (n = 29 implants). Clinical (probing depth [PD], bleeding on probing [BOP], and plaque index [PI]) and radiographic (peri‑implant crestal bone loss [PCBL]) peri‑implant variables were recorded. Bacterial species including Porphyromonas gingivalis and Treponema denticola were evaluated from peri‑implant plaque biofilms. Levels of interleukin (IL)-1β and IL-6 were assessed after the collection of peri‑implant sulcular fluid. All the evaluations were carried out at baseline, 3- and 6-months. The significance level was set to p < 0.05. Results All clinical parameters significantly reduced within both treatment groups (P<0.05). Intra-group comparison indicates that there was statistically significant reduction in PD and suppuration for ICG-PDT group (P<0.05). There was a statistically significant difference in the BOP between ICG-PDT and PIMD groups at both follow-up periods (P<0.001). However, there was a significant difference for PD (P = 0.001), suppuration (P = 0.01), and PCBL (P = 0.04) on 6 months follow-up between ICG-PDT and PIMD groups, respectively. Only ICG-PDT showed a significant reduction in P. gingivalis and T. denticola on both 3 months and 6 months follow-up compared to baseline. PIMD showed a statistically significant reduction only on 3 months follow-up compared to baseline. This reduction was maintained for both the species when dental implants were treated with ICG-PDT. However, PIMD failed to maintain this reduction until 6 months. Only at 3 months assessment that both treatment groups showed statistically significant reduction in IL-1β and IL-6 with no significant difference between the groups. Both biomarkers failed to maintain the reduction in both groups and significantly increased levels for IL-1β was noted at 6 months follow up Conclusion Multiple application of indocyanine-green mediated photodynamic therapy resulted in improved clinical and microbial parameters among type 2 DM subjects in the treatment of peri‑implantitis. This clinical trial was registered in the ClinicalTrials.gov Protocol Registration and Results System with registration record number: NCT04833569.

Abstract
On-demand screening, real-time monitoring and rapid diagnosis of ubiquitous diseases, such as diabetes, at early stages are indispensable in personalised treatment. Emerging impacts of nano/microscale materials on optical and portable biosensor strips and devices have become increasingly important in the remarkable development of sensitive visualisation (i.e. visible inspection by the human eye) assays, low-cost analyses and personalised home testing of patients with diabetes. With the increasing public attention regarding the self-monitoring of diabetes, the development of visual readout, easy-to-use and wearable biosensors has gained considerable interest. Our comprehensive review bridges the practical assessment gap between optical bio-visualisation assays, disposable test strips, sensor array designs and full integration into flexible skin-based or contact lens devices with the on-site wireless signal transmission of glucose detection in physiological fluids. To date, the fully modulated integration of nano/microscale optical biosensors into wearable electronic devices, such as smartphones, is critical to prolong periods of indoor and outdoor clinical diagnostics. Focus should be given to the improvements of invasive, wireless and portable sensing technologies to improve the applicability and reliability of screen display, continuous monitoring, dynamic data visualisation, online acquisition and self and in-home healthcare management of patients with diabetes.

Abstract
OBJECTIVES This study aims to investigate awareness of oral health care and health status among elderly people in nursing homes in Taiyuan. Strategies for preventing and treating oral diseases and improving the quality of life of the elderly in nursing homes were formulated on the basis of analyzed data. METHODS A total of 359 participants from 48 nursing homes in six districts were selected randomly. Awareness, attitude, and behavior with regard to oral health care among the elderly were investigated through a survey using questionnaires and oral health examinations. Data were statistically analyzed with SPSS 20.0. RESULTS Among the elderly in the nursing homes in Taiyuan, awareness and behavior with regard to oral health care were deficient and inappropriate, and thus professional guidance was needed. In addition to method and time of brushing teeth and bad oral habits, the oral health status of the elderly was statistically affected by age and education. Compared with the data of the Fourth National Oral Epidemiological Investigation, the number of elderly people aged 55-64 or 65-74 years who brush their teeth every day and accept oral diagnosis and treatment was lower. However, the ratios of edentulous and missing teeth without treatment were higher than the national average level for the same age groups. CONCLUSIONS The awareness and attitude of the elderly in nursing homes with regard to oral health care are unsatisfactory, and their oral health status is poor. Education on oral health care, development of good oral care habits, and regular oral health examination are essential to the maintenance of oral health in elderly people.

Abstract
ZusammenfassungDie Covid-19-Pandemie hat das deutsche Gesundheitssystem im Jahr 2020 vor erhebliche Herausforderungen gestellt. In diesem Zusammenhang ist es bemerkenswert, dass für die Zahnmedizin kein sogenannter Rettungsschirm aufgespannt wurde. Dies bedeutet, dass nach Ansicht der Bundesregierung Zahnärzte als nicht systemrelevant eingestuft wurden und somit offiziell auch nicht zu den Ärzten gehören. Diese Annahme ist grundfalsch und gefährlich, wie im Folgenden anhand eines wichtigen Beispiels erörtert wird.Das SARS-CoV-2-Virus führt bei infizierten Personen zu einem Beschwerdebild von leichten Erkältungszeichen bis hin zu lebensbedrohlichen beatmungsbedürftigen COVID-19-Pneumonien. Ein besonderes Risiko für schwere Verläufe haben Menschen höheren Alters sowie Patienten mit Diabetes, Bluthochdruck und anderen schweren Erkrankungen. Die Haupteintrittspforte für das SARS-CoV-2-Virus in den menschlichen Körper ist u. a. die orale Mukosa, denn die Viren reichern sich dort bevorzugt an und der ACE2-Rezeptor wird dort hochgradig exprimiert. Dieser Penetrationsweg erklärt die häufigeren schweren Verläufe bei älteren Diabetespatienten, deren Immunsystem bereits generell beeinträchtigt ist. Diabetes mellitus induziert eine chronische systemische Entzündung, die sich gerade im Mundbereich regelmäßig als Parodontitis manifestiert. Bei Diabetikern zwangsläufig oft auftretende Hyperglykämien schwächen die Mukosa-Barriere zusätzlich. Es ist daher dringend ratsam, bei Präventionsmaßnahmen für Diabetespatienten den Mund- und Rachenraum nicht zu ignorieren. Neben der parodontalprophylaktischen Betreuung ist gerade in Absenz von Zahnärzten die aktivierte Matrix-Metalloproteinase 8 (aMMP8) ein etablierter Biomarker. Die aktuellen Empfehlungen zur Prävention der SARS-CoV-2-assoziierten COVID-19-Erkrankung sollte daher um die Aspekte der Messung und Sanierung des Mund- und Rachenraums sowie einer regelmäßigen Desinfektion der oralen Mukosa erweitert werden.

Abstract
OBJECTIVE This study aimed to investigate the effect of the low intensity pulsed ultrasound (LIPUS) on the dentoalveolar structures during orthodontic force application in ex-vivo model using mandible slice organ culture (MSOC) of diabetic rats. DESIGN 18 male Wistar rats with a mean weight (275 g) were randomly divided into three main groups: 1) normal rats, 2) Insulin treated diabetic rats, and 3) diabetic rats. Diabetes mellitus (DM) was induced by streptozotocin. Four weeks later, rats were euthanized, mandibles were dissected, divided into 1.5-mm slices creating mandible slice organ cultures (MSOCs). MSOCs were cultured at 37 °C in air with 5 % CO2. The following day, orthodontic spring delivering a 50-g of force was applied to each slice. In each group, rats were randomly assigned to 2 subgroups; one received 10 min of LIPUS daily and the other was the control. Culture continued for 7 days, and then the sections were prepared for histological and histomorphometric analysis. RESULTS For all study groups (Normal, Insulin Treated Diabetic and Diabetic), LIPUS treatment significantly increased the thickness of predentin, cementum, and improved bone remodeling on the tension side and increased odontoblast, sub-odontoblast, and periodontal ligaments cell counts and bone resorption lacunae number on the compression side. CONCLUSIONS Application of LIPUS treatment for 10 min daily for a week enhanced bone remodeling and repair of cementum and dentin in normal as well as diabetic MSOCs.

Abstract
BACKGROUND Peri-implant disease (PID) has not been directly linked to pathological organ changes. The present study assessed the dynamics of serum biochemical parameters in a model of experimental peri-implantitis in dogs, followed by open flap debridement. METHODS Seven male beagle dogs comprised the study group. Procedures were performed as follows-extractions of two premolars and one molar on each mandibular quadrant (Day 0); bone healing time (week14); placement of four rough-surface endoosseous implants, two on each mandibular side; implant uncovering (week 28); induction of experimental peri-implantitis by the use of three ligatures (weeks 31, 34, 37) followed by open flap debridement (week 42). Serum biochemical analysis following each procedure was compared to baseline. Biochemical parameters were assigned into four subsets of variables-inflammation, renal function, liver function, and blood glucose. Wilcoxon paired tests were conducted in order to identify statistically significant differences between baseline data and values obtained after each procedure RESULTS: Following experimental peri-implantitis, the dynamics of renal parameters and blood glucose were minimal whereas statistically significant (P < 0.05) increases were noted for inflammatory (total protein and albumin concentrations) and hepatic (ALT, AST) parameters. A statistically significant (P < 0.05) decrease was only noted for total bilirubin. After open flap debridement, inflammatory (total protein and albumin concentrations) and hepatic (AST) parameters returned to baseline. CONCLUSIONS Within their limits, the present results indicate that: (a) PID affects inflammatory and hepatic serum biochemical parameters, and (b) following open flap debridement most of the values returned to baseline.

Abstract
BACKGROUND Indigenous Australians suffer from higher rates of oral disease and have more untreated dental problems and tooth extractions than the general population. Indigenous Australians also have lower rates of accessing oral health services and are more likely to visit for a problem rather than a check-up. Multiple issues effect health service and prevention programs including: characteristics of health services such as distances to health services; existence of social and cultural barriers; available wealth and social support; and, characteristics of the individual and community including the importance given to the disease. This paper seeks to explore the perceived importance of oral health within a rural Indigenous community in Australia and the factors influencing this perception. METHODS The study used a phenomenology research design incorporating focus group discussions and in-depth interviews. It was undertaken in partnership with communities' Health Action Group who guided the focus, implementation and reporting of the research. A convenience sample was recruited from established community groups. Thematic analysis on the transcripts was completed. RESULTS Twenty-seven community members participated in three focus groups and twelve in-depth interviews. The study found that the community gives high priority to oral health. Factors influencing the importance include: the perceived severity of symptoms of oral disease such as pain experienced due to tooth ache; lack of enabling resources such as access to finance and transport; the social impact of oral disease on individuals including impact on their personal appearance and self-esteem; and health beliefs including oral health awareness. Participants also noted that the importance given to oral health within the community competed with the occurrence of multiple health concerns and family responsibilities. CONCLUSION This paper highlights the high importance this rural Indigenous community gives to oral health. Its findings suggest that under-utilisation of oral health services is influenced by both major barriers faced in accessing oral health services; and the number and severity of competing health and social concerns within the community. The study results confirm the importance of establishing affordable, culturally appropriate, community-based oral health care services to improve the oral health of rural Indigenous communities.

Abstract
Caffeic acid phenethyl ester (CAPE) is used as a therapeutic agent to prevent bone loss. We determined the effects of systemically administered CAPE on alveolar bone loss and oxidative stress in diabetic rats with experimental periodontitis. Forty male rats were divided into four equal groups: control, experimental periodontitis (EP), EP-diabetes mellitus (EP-DM) and EP-DM-CAPE. DM was induced by streptozotocin, then lipopolysaccharide was injected to induce periodontitis. CAPE was administered to the EP-DM-CAPE group daily for 15 days. Then, serum samples were taken and the rats were sacrificed for histological analyses. Serum interleukin (IL-1β) and oxidative stress also were evaluated. Alveolar bone loss was assessed histomorphometrically. Alveolar bone loss and IL-1β levels were significantly less in the EP-DM-CAPE and EP groups compared to the EP-DM group. Oxidative stress was significantly less in the EP-DM-CAPE group compared to the EP and EP-DM groups. Receptor activator of nuclear factor kappa-B ligand (RANKL) levels were significantly higher in the EP-DM group compared to the disease groups. CAPE significantly reduced RANKL levels in the EP-DM-CAPE group compared to the EP-DM group. We found that CAPE treatment significantly inhibited DM induced oxidative stress and RANKL induced osteoclastogenesis and alveolar bone loss in diabetic rats with periodontitis.

Abstract
In recent years, the incidence of diabetes mellitus and cancer has increased sharply; indeed, these have become the two most important diseases threatening health and survival. Head and neck (HN) tumors are the sixth most common malignancies in humans. Numerous studies have shown that there are many common risk factors for diabetes mellitus and HN squamous cell carcinoma, including advanced age, poor diet and lifestyle, and environmental factors. However, the mechanism linking the two diseases has not been identified. A number of studies have shown that diabetes affects the development, metastasis, and prognosis of HN cancer, potentially through the associated hyperglycemia, hyperinsulinemia and insulin resistance, or chronic inflammation. More recent studies show that metformin, the first-line drug for the treatment of type 2 diabetes, can significantly reduce the risk of HN tumor development and reduce mortality in diabetic patients. Here, we review recent progress in the study of the relationship between diabetes mellitus and HN carcinogenesis, and its potential mechanisms, in order to provide a scientific basis for the early diagnosis and effective treatment of these diseases.

Abstract
BACKGROUND Diagnosis of prediabetic stage is very important for prevention of diabetes and complications. This stage may be associated with some oral lesions. Only a few studies are available on the oral status of prediabetic patients and incidence of oral lesions in this population. This study aimed to compare some oral complications between prediabetic and healthy control groups. METHODS The present two-group cross-sectional study was carried out on 302 prediabetic and non-diabetic (healthy) 20- to 60-year-old subjects. In this study, data on age, gender, educational level, medications use, smoking, and some other variables were extracted through history taking. In addition, orodental examination was carried out by an oral medicine specialist to diagnose oral lesions including candidiasis, lichen planus, periodontitis, gingivitis, xerostomia, delayed wound healing, geographic tongue, fissured tongue, and burning mouth sensation. Data entry and analysis was performed by SPSS version 22 software, and P value and odds ratio (OR) were calculated to show statistical relationship between variables. RESULTS The most common oral lesion in prediabetic subjects was periodontitis (27.2%), followed by gingivitis (14.7%) and xerostomia (11.3%). In the control group, gingivitis (20.5%) followed by periodontitis (11.3%) are common oral lesions. Candidiasis (P = 0.036), periodontitis (P < 0.001), and xerostomia (P < 0.001) in prediabetic subjects were higher than control group that is statistically significant. Regression analysis showed that in the prediabetic group, periodontitis [OR = 2.91, confidence interval (CI): 1.54-5.49] and xerostomia (OR = 18.51, CI = 2.42-141.45) were significantly more prevalent than healthy subjects. CONCLUSION Based on the results, glucose intolerance stage exhibited a significantly higher oral problems such as periodontitis and xerostomia than healthy euglycemic stage.

Abstract
BACKGROUND Type 1 diabetes (T1D) is associated with delayed tissue healing and bone loss. Periodontal tissues during tooth movement (OTM) in T1D and under diabetic treatment are poorly understood. We aimed to study the effect of metformin as an add-on to insulin therapy on periodontal structures during OTM in T1D rats. METHODS Rats were divided into normoglycemic (NG, n = 20) and streptozotocin-induced diabetic groups that were untreated (T1D, n = 20), treated with insulin (I-T1D, n = 20), or treated with insulin plus metformin (IM-T1D, n = 20). After 7 days of treatment, the first right upper molar (M1) was moved mesially. At days 0, 3, 7 and 14, the pattern of OTM and the periodontal tissues were analyzed by micro-CT, histomorphometry, and immunohistochemistry for TRAP. RESULTS In T1D, major osteoclastogenic activity and bone loss versus other groups were confirmed by a greater TRAP-positive cell number and reabsorption surface on both the pressure and tension sides for 14 days (p < 0.01). Additionally, we observed low bone volume density. Metformin plus insulin resulted in a daily insulin dose reduction and major glycemic control versus I-T1D. Although no significant differences were observed between I-T1D and IM-T1D, the tooth displacement and inclination, periodontal ligament thickness, and alveolar bone density on the pressure side in IM-T1D were similar to that of NG (p > 0.05). CONCLUSION Antidiabetic treatment reduces severe periodontal damage during applied orthodontic force in T1D untreated rats. Metformin as an add-on to insulin therapy resulted in glycemic control and a periodontal tissue response to orthodontic forces that was similar to that of normoglycemic rats.

Abstract
BACKGROUND There is no data available on the prevalence of oral mucosal lesion and candida infection among DM patients which necessitate conducting a local or nation-wide study to assess the oral mucosa lesions and candida prevalent in diabetic patients in Riyadh, Saudi Arabia. OBJECTIVES The objective of the present study was to characterize oral mucosa lesions, and the prevalence of yeasts in diabetic patients and their association with the risk factors in comparison with a group of non-diabetic controls. METHODS Study design: A cross-sectional comparative study was conducted assuming 50% of the diabetic patients have oral lesions compared to nondiabetic patients and a power of 80% with 5% level of significance, the minimum required sample size was estimated to be 115 in each group. The buccal swabs were collected to isolate Candida species from the individual patient with a current and former history of diabetes. The laboratory findings were collected and the clinical examination of the oral mucosa was processed at the department of microbiology. RESULTS The results inferred a significant presence of oral mucosa alterations in the diabetic group. A majority of the patients were suffering from type 2 diabetes for the past 10 years. C. albicans was the predominant yeast, followed by. C. tropicalis and C. krusei nonalbicans species that were most frequently isolated. Diabetes and smoking habit were the two risk factors for oral mucosa alterations. CONCLUSIONS The study found a significant presence of oral mucosa alterations in the diabetic group and the fungal infection tended to be more in the diabetic group with a high incidence of C. albicans. The presence of diabetes and smoking habit were two risk factors identified as significant for oral mucosa alterations. The significant variation in education level in groups indicates that education would help to enhance the prognosis in diabetic patients and healthcare behavior.

Tynan A, Deeth L, McKenzie D. An integrated oral health program for rural residential aged care facilities: a mixed methods comparative study. BMC Health Serv Res 2018; 18:515. [PMID: 29970073 PMCID: PMC6029389 DOI: 10.1186/s12913-018-3321-5] [Citation(s) in RCA: 25] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2017] [Accepted: 06/22/2018] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND People in residential aged care facilities (RACF) are at very high risk of developing complex oral diseases and dental problems. A multidisciplinary approach incorporating oral health professionals and RACF staff is important for improving and sustaining oral health in RACFs. However, difficulties exist with access to oral health services for RACFs, particularly those in regional and rural areas. This study investigated the impact and experience of an integrated oral health program utilising tele-dentistry and Oral Health Therapists (OHT) in RACFs in a rural setting within Australia. METHODS A mixed method comparison study was undertaken. Two hundred fifty-two clinical audits were completed across nine facilities with and without access to the integrated oral health program. Twenty-seven oral health quality of life surveys were completed with eligible residents. One focus group discussions (FGD) and eight interviews were completed with RACF staff. Thematic analysis was conducted on the transcribed FGDs and IDIs. Quantitative data were analysed using descriptive statistics. RESULTS Audits showed an improved compliance to Australian Aged Care Quality Accreditation Standards for oral health in the facilities with access to the integrated program compared to those without the program. Thematic analysis revealed that facilities with the integrated program reported improvements in importance placed on OH, better access to OH services and training, and decreased disruption of residents, particularly those with high care needs. CONCLUSIONS The integrated oral health program incorporating OHTs and tele-dentistry shows potential to improve the oral health outcomes of residents of RACFs. Improvements for managing oral health of residents with high care needs were observed. RACFs without easy access to an oral health service will also likely benefit from the increased support and training opportunities that the program enables.

Abstract
Periodontitis is characterized by inflammation of the periodontium and leads to loss of teeth if untreated. Although a number of surgical and pharmacological options are available for the management of periodontitis, it still affects a large proportion of population. Recently, metformin (MF), an oral hypoglycemic, has been used to treat periodontitis. The aim of this review is to systematically evaluate the efficacy of MF in the treatment of periodontitis. An electronic search was carried out using the keywords 'metformin', 'periodontal' and 'periodontitis' via the PubMed/Medline, ISI Web of Science and Google Scholar databases for relevant articles published from 1949 to 2016. The addressed focused question was: 'Is metformin effective in reducing bone loss in periodontitis? Critical review and meta-analysis were conducted of the results obtained in the selected studies. Following the removal of the duplicate results, the primary search resulted in 17 articles and seven articles were excluded based on title and abstract. Hence, 10 articles were read completely for eligibility. After exclusion of four irrelevant studies, six articles were included. The topical application of MF resulted in improved histological, clinical and radiographic outcomes. Additionally, results from the meta-analysis indicated that application of metformin improved the clinical and radiographic outcomes of scaling and root-planing, but at the same time heterogeneity was evident among the results. However, because of a lack of histological and bacterial studies, in addition to short follow-up periods and risk of bias, the long-term efficacy of MF in the treatment of bony defects is not yet ascertained. Further studies are needed to envisage the long-term efficacy of MF in the management of periodontitis.

Abstract
CONTEXT Xerostomia and hyposalivation are associated with diabetes. Research is sparse regarding electrostimulation as a mainstream therapy for salivary gland hypofunction. OBJECTIVE To clinically evaluate the effectiveness of transcutaneous electric nerve stimulation (TENS) therapy in stimulating whole salivary flow among patients with xerostomia and hyposalivation caused by diabetes mellitus. DESIGN Forty patients between age 30 to 75 years with diabetes mellitus categorized as controlled or uncontrolled who had subjective symptoms of xerostomia and an objective sign of hyposalivation were included in a prospective study. MAIN OUTCOME MEASURES Unstimulated saliva through the "low forced spitting" method and stimulated saliva collection using TENS were assessed and compared. Longer-term effects of TENS application were evaluated by recalling the patient 24 hours later. RESULTS A statistically significant increase in stimulated whole saliva after TENS application in continuous mode (p < 0.001) was demonstrated compared with unstimulated saliva, especially in xerostomic patients with diabetes. Burst mode inferred a statistically significant decrease in salivary flow (p < 0.001). CONCLUSION In patients with diabetes with xerostomia and hyposalivation, TENS was highly effective in stimulating whole salivary flow.

Abstract
OBJECTIVE Grape seed proanthocyanidine extract (GSPE) is a strong antioxidant derived from the grape seeds (Vitis vinifera, Terral J.F.) and has a polyphenolic structure with a wide range of biological activity. The aim of the present study was to evaluate the effects of GSPE on alveolar bone loss and histopathological changes in rats with diabetes mellitus and ligature-induced periodontitis. MATERIAL AND METHODS Forty rats were divided into 6 study groups. Control (C, 6 rats) group, periodontitis (P, 6 rats) group, diabetes (D, 6 rats) group, diabetes and periodontitis (D+P, 6 rats) group, diabetes, periodontitis and 100 mg/kg/day GSPE (GSPE-100, 8 rats), and diabetes, periodontitis and 200 mg/kg/day GSPE (GSPE-200, 8 rats) group. Diabetes mellitus was induced by intraperitoneal injection of a single dose of streptozotocin (60 mg/kg). Periodontitis was induced via ligation method. Silk ligatures were placed at the mandibular right first molars. GSPE was administered by oral gavage. After 30 days, all rats were killed. Alveolar bone loss was measured morphometrically via a stereomicroscope. For histopathological analyses, Alizarin red staining, and matrix metalloproteinase (MMP)-8, vascular endothelial growth factor and hypoxia inducible factor (HIF)-1α immunohistochemistry were performed. Tartrate-resistant acid phosphatase-positive osteoclast cells and relative total inflammatory cells were also determined. RESULTS The highest alveolar bone loss was observed in the D+P group (P < .05). GSP-200 group decreased alveolar bone loss (P < .05). The D+P group had the highest osteoclast counts, but the difference was not significant compared to the P, GSPE-100 and GSPE-200 groups (P > .05). The inflammation in the D+P group was also higher than the other groups (P < .05). The osteoblast numbers increased in the GSPE-100 and GSPE-200 groups compared to the P and D+P groups (P < .05). MMP-8 and HIF-1α levels were highest in the D+P group and GSPE significantly decreased these levels (P < .05). CONCLUSION Within the limits of this animal study, it can be suggested that GSPE administration may decrease periodontal inflammation and alveolar bone loss via decreasing MMP-8 and HIF-1α levels and increase osteoblastic activity in diabetic rats with experimental periodontitis.

Abstract
OBJECTIVE The aim of this study was to develop a chitosan-metformin based intrapocket dental film (CMIDF) for applications in the treatment of periodontitis and alveolar bone loss in an rat model of periodontitis. DESIGN CMIDF inserts were fabricated by the solvent casting technique. The fabricated inserts were evaluated for physical characteristics such as folding endurance, surface pH, mucoadhesive strength, metformin content uniformity, and release. X-ray diffraction analysis indicates no crystallinity of metformin in presence of chitosan which confirmed successful entrapment of metformin into the CMIDF. Fourier-transform infrared spectroscopy revealed stability of CMIDF and compatibility between metformin and chitosan. Periodontitis was induced by a combination of Porphyromonas gingivalis- lipopolysaccharide injections in combinations with ligatures around the mandibular first molar. We divided rats into 5 groups (8 rats/group): healthy, untreated periodontitis; periodontitis plus CMIDF-A (1.99±0.09mg metformin; total mass-4.01±0.05mg), periodontitis plus CMIDF-B (2.07±0.06mg metformin; total mass-7.56±0.09mg), and periodontitis plus chitosan film (7.61±0.08mg). After four weeks, mandibles were extracted to evaluate alveolar bone loss by micro-computerized tomography and histological techniques. RESULTS Alveolar bone was intact in the healthy group. Local administration of CMIDF resulted in significant improvements in the alveolar bone properties when compared to the untreated periodontitis group. The study reported here demonstrates that novel CMIDF showed good antibacterial activity and effectively reduced alveolar bone destruction in a rat model of experimental periodontitis. CONCLUSIONS Novel CMIDF showed good antibacterial activity and improved alveolar bone properties in a rat model.

Abstract
Aim: A semisynthetic primary bile acid (PBA) has exerted hypoglycemic effects in Type 1 diabetic animals, which were hypothesized to be due to its anti-inflammatory and cellular glucose-regulatory effects. Thus, the research purpose aimed to examine antidiabetic effects of a PBA, in terms of cellular inflammation and survival and insulin release, in the context of supporting β-cell delivery and Type 1 diabetic treatment. Materials & methods: 10 formulations were prepared, five without PBA (control) and five with PBA (test). Formulations were used to microencapsulate pancreatic β cells and the microcapsules were examined for morphology, cell viability, insulin release and inflammation. Results & conclusion: PBA improved cell viability, insulin release and reduced inflammation in a formulation-dependent manner, which suggests potential use in cell delivery and diabetes treatment.

Abstract
A new series of Deacetylsarmentamide A and B derivatives, amides and sulfonamides of 3,4-dihydroxypyrrolidines as α-glucosidase inhibitors were designed and synthesized. The biological screening test against α-glucosidase showed that some of these compounds have the positive inhibitory activity against α-glucosidase. Saturated aliphatic amides were more potent than the olefinic amides. Among all the compounds, 5o/6o having polar -NH2 group, 10f/11f having polar -OH group on phenyl ring displayed 3-4-fold more potent than the standard drugs. Acarbose, Voglibose and Miglitol were used as standard references. The promising compounds 6i, 5o, 6o, 10a, 11a, 10f and 11f have been identified. Molecular docking simulations were done for compounds to identify important binding modes responsible for inhibition activity of α-glucosidase.

Abstract
Context: Oral exfoliative cytology is a simple, nonaggressive technique that is well accepted by patients. Therefore, it is an attractive option, which aids in the diagnosis and observation of epithelial atypias associated with oral mucosal diseases. Aims: The aim of this study was to evaluate and compare the quantitative and qualitative alterations in exfoliative smears from type 2 diabetics and healthy individuals. Patients and Methods: The study includes 30 type 2 diabetics and 30 healthy persons of both sexes. PAP and hematoxylin and eosin (H and E) stained smears were prepared from buccal mucosa (BM), tongue (T), floor of the mouth (FOM), and palate (P). Under a light microscope, 50 clearly defined unfolded epithelial cells were quantitatively evaluated for cellular area (CA), nuclear area (NA), and cellular-to-nuclear area ratio (CA:NA) and assessed for morphological features. Statistical Analysis: Collected data was manually entered into the Statistical Package for the Social Sciences version 13.5 for analysis. Student's t-test was used at 95% confidence interval. Results: Quantitative assessment of the overall mean CA was less, mean NA was more, and mean CA:NA was less in diabetics than that in healthy persons at all the four sites. Diabetic oral cells showed qualiative cytoplasmic and nuclear alterations: cytoplasmic vacuoles, karyorrhexis, karyolysis, pyknosis, peri-nuclear halo, binucleation, nuclear vacuoles, inflammation, and microbial colonies. Conclusion: Oral cytology from type 2 diabetics is associated with detectable cytomorphological changes with alteration in size of the cell and nucleus, which is site specific, indicating epithelial cell degeneration in cytoplasm and nucleus.

Abstract
Alveolar bone - the bony ridge containing the tooth sockets - stands out by its remodeling activity where bone is being formed and resorbed at a much higher rate than in any other bony tissue. Teeth that are anchored in the jaw through the periodontal ligament exert very large localized loads during mastication that could lead to a unique adaptation of the collagen/mineral structure in the bone. Our aim was to characterize the nanostructure of alveolar bone and to determine the influence of diabetes on structural characteristics of the mineralized matrix. Using small- and wide-angle X-ray scattering (SAXS/WAXS), we studied a spontaneous diabetic mouse model (KK+) and its corresponding healthy controls (KK-) (n=6) to determine the size and mutual alignment of the mineral nanoparticles embedded in the collagen matrix. On cross-sections (buccal-lingual) of the first molar multiple line scans with a spatial resolution of 30μm were performed on each sample, from the lingual to the buccal side of the mandible. Mineral particle thickness and length are decreasing towards the tooth in both buccal and lingual sides of alveolar bone. While mineral particles are well aligned with the long axis of the tooth on the buccal side, they are in a quarter of the measurements oriented along two preferred directions on the lingual side. These nanostructural differences can be interpreted as the result of an asymmetric loading during mastication, leading to a tilting of the tooth in its socket. In diabetic mice particle thicknesses are smaller compared to control animals.

Starting from the lead isodaphnetin, a natural product inhibitor of DPP-4 discovered through a target fishing docking based approach, a series of novel 2-phenyl-3,4-dihydro-2H-benzo[f]chromen-3-amine derivatives as potent DPP-4 inhibitors are rationally designed utilizing highly efficient 3D molecular similarity based scaffold hopping as well as electrostatic complementary methods. Those ingenious drug design strategies bring us approximate 7400-fold boost in potency. Compounds 22a and 24a are the most potent ones (IC50 ≈ 2.0 nM) with good pharmacokinetic profiles. Compound 22a demonstrated stable pharmacological effect. A 3 mg/kg oral dose provided >80% inhibition of DPP-4 activity within 24 h, which is comparable to the performance of the long-acting control omarigliptin. Moreover, the efficacy of 22a in improving the glucose tolerance is also comparable with omarigliptin. In this study, not only promising DPP-4 inhibitors as long acting antidiabetic that are clinically on demand are identified, but the target fish docking and medicinal chemistry strategies were successfully implemented.

Abstract
AIM To explore how home care providers can support older people to maintain good oral health through implementing a model called Better Oral Health in Home Care (BOHHC). METHODS A mixed method, pre- to post-implementation design was used. The Promoting Action on Research Implementation in Health Services framework informed the model's implementation process. RESULTS High levels of dental need were identified at pre-implementation. Older people self-reported significant oral health improvements following the introduction of tailored home care strategies by care workers, who in turn reported a better understanding and knowledge of the importance of oral care for older people. CONCLUSION The BOHHC Model provided an evidence-based approach for community-based prevention and early detection of oral health problems. Improving oral health for older people in the home care setting has significant practice and policy implications which require ongoing intersectoral facilitation involving aged care, vocational health education and dental sectors.

Abstract
Chronic hyperglycemia is associated with impaired wound healing and higher susceptibility to infections. It is unclear whether patients with diabetes mellitus (DM) present more oral mucosal disorders compared to control groups. The objectives were to compare (a) the prevalence rates of oral mucosal disorders in the DM and non-DM population and (b) the prevalence rates of specific disorders in the DM and non-DM population. Full-text articles were included if they met the following inclusion criteria: (a) they must be original articles from scientific journals, (b) they must be only cross-sectional studies in English, (c) the prevalence of oral mucosal disorders in DM patients must be evaluated, (d) results must be compared with a healthy control group, and (e) oral mucosal disorders must be specified in DM and non-DM group. All studies showed higher prevalence of oral mucosal disorders in DM patients in relation to non-DM population: 45-88% in type 2 DM patients compared to 38.3-45% in non-DM groups and 44.7% in type 1 DM patients compared to 25% in non-DM population. Tongue alterations and denture stomatitis were the most frequent significant disorders observed. The quality assessment following the Joanna Briggs Institute (JBI) Prevalence Critical Appraisal Tool showed the low quality of the existing studies.

Abstract
CONTEXT The dental setting represents an unrealized opportunity to increase adherence to preventive services and improve health outcomes. OBJECTIVE To compare adherence to a subset of Healthcare Effectiveness Data and Information Set (HEDIS) measures among a population that received dental care with a population that did not receive dental care. DESIGN Using a retrospective cohort design, we identified 5216 adults who received regular dental care and 5216 persons who did not. The groups were matched on propensity scores, were followed for 3 years, and retained medical and dental benefits. Receipt of dental care was defined as 1 or more dental visits in each 12-month period. MAIN OUTCOME MEASURES Outcome measures were assessed in a subpopulation that qualified for 1 of 5 HEDIS denominator groups (dental = 4184 patients; nondental = 3871 patients). They included 3 preventive measures (cervical, colorectal, and breast cancer screening), 4 chronic disease management services (hemoglobin A1c and low-density lipoprotein cholesterol testing, and nephropathy and retinopathy screening among the diabetes mellitus [DM] population), and 4 health outcome measures (poor glycemic control, low-density lipoprotein cholesterol control, blood pressure control in the DM population, and blood pressure control in the hypertensive population). RESULTS Dental care was associated with higher adherence to all three cancer screening measures, one of four disease management services (higher retinopathy screening), and three of four health outcomes (better glycemic control in the DM population and better blood pressure control in the DM and hypertensive populations). CONCLUSIONS Dental care was associated with improved adherence to 7 of 11 HEDIS measures.

Abstract
The goal of this study was to investigate individual and contextual factors associated with dental care utilization by U.S. informal caregivers. The sample included all 2010 Behavioral Risk Factor Surveillance System respondents who completed the caregiver module and reported providing care for 1 year or more to an individual aged ≥ 50 years or older (n = 1,196). Multiple logistic regressions were used to examine associations of caregiver and care characteristics and county-level contextual characteristics (from Area Resource File data) with two outcomes: dental visits and dental cleaning during previous year. Caregivers with health insurance coverage and higher education were more likely to use dental care; those who had lost more teeth and who were spouse caregivers were less likely to do so. Community characteristics were not correlated with caregivers' use of dental care. Our findings suggest that better access to dental care could improve dental care utilization by caregivers.

Abstract
Context: Diabetes mellitus can have profound effects upon the oral tissues especially in patients with poor glycemic control being prone to severe and/or recurrent infections particularly candidiasis. The main aim was to study the association between Type 1 and Type 2 diabetes mellitus and candidal carriage. Materials and Methods: The study design comprised of previously diagnosed 30 patients each with type 1 diabetes mellitus (Group A) and type 2 diabetes mellitus (Group B) and 30 age-, sex- and dental status-matched healthy non-diabetic individuals as controls (Group C). The saliva samples were collected and inoculated onto Sabouraud dextrose agar (SDA) and chromogenic agar culture medium. Candidal colony forming units per ml (CFU/ml) values were determined. Statistical Analysis: Data were analyzed by χ2 test, Mann-Whitney U-test, Spearman's rank correlation and Karl Pearson's correlation coefficient. Results: Data analysis showed statistically significant higher positive candidal growth in Group A and Group B when compared to Group C. The CFU/ml values were significantly higher in Groups A and B as compared with Group C. Significant positive correlation of CFU/ml with fasting blood sugar level and HbA1c% in both Groups A and B was seen. Oral signs and symptoms observed in diabetics were dry mouth, burning sensation, fissuring and atrophic changes of tongue and erythematous areas, which positively correlated with candidal load. Conclusion: The glycemic control status of the diabetic patients may directly influence candidal colonization. The quantitative and biochemical characterization allows better insight into the study of association of diabetes mellitus and candida.

Abstract
OBJECTIVE The purpose of this study was to evaluate the effects of systemically administered boric acid on alveolar bone loss, histopathological changes and oxidant/antioxidant status in ligature-induced periodontitis in diabetic rats. MATERIALS AND METHODS Forty-four Wistar rats were divided into six experimental groups: (1) non-ligated (NL, n = 6) group, (2) ligature only (LO, n = 6) group, (3) Streptozotocin only (STZ, n = 8) group, (4) STZ and ligature (STZ+LO, n = 8) group, (5) STZ, ligature and systemic administration of 15 mg/kg/day boric acid for 15 days (BA15, n = 8) group and (6) STZ, ligature and systemic administration of 30 mg/kg/day boric acid for 15 days (BA30, n = 8) group. Diabetes mellitus was induced by 60 mg/kg streptozotocin. Silk ligatures were placed at the gingival margin of lower first molars of the mandibular quadrant. The study duration was 15 days after diabetes induction and the animals were sacrificed at the end of this period. Changes in alveolar bone levels were clinically measured and tissues were histopathologically examined. Serum total antioxidant status (TAS), total oxidant status (TOS), calcium (Ca) and magnesium (Mg) levels and oxidative stress index (OSI) were evaluated. Primary outcome was alveolar bone loss. Seconder outcome (osteoblast number) was also measured. RESULTS At the end of 15 days, the alveolar bone loss was significantly higher in the STZ+LO group compared to the other groups (p < 0.05). There was no significant difference in alveolar bone loss between the STZ+LO 15 mg/kg boric acid and STZ+LO 30 mg/kg boric acid groups (p > 0.05). Systemically administered boric acid significantly decreased alveolar bone loss compared to the STZ+LO group (p < 0.05). The osteoblast number in the BA30 group was significantly higher than those of the NL, STZ and STZ+LO groups (p < 0.05). Inflammatory cell infiltration was significantly higher in the STZ+LO group the other groups (p < 0.05). Serum TAS levels were significantly higher in the NL and LO groups than the other groups (p < 0.05). The differences in TOS levels were not found to be significant among all the groups (p > 0.05). The OSI values of the BA30 group were significantly lower than the STZ+LO group (p < 0.05). Also, the differences in serum calcium and magnesium levels were insignificant among the all groups (p > 0.05). CONCLUSION Within the limits of this study, it can be suggested that BA, when administered systemically, may reduce alveolar bone loss in the diabetic rat model.

Abstract
Diabetes and infections are associated with a high risk of implant failure. However, the effects of such conditions on the electrochemical stability of titanium materials remain unclear. This study evaluated the corrosion behavior of a Ti-6Al-4V alloy, with a smooth surface or conditioned by double-acid-etching, in simulated body fluid with different concentrations of dextrose and lipopolysaccharide. For the electrochemical assay, the open-circuit-potential, electrochemical impedance spectroscopy, and potentiodynamic test were used. The disc surfaces were characterized by scanning electron microscopy and atomic force microscopy. Their surface roughness and Vickers microhardness were also tested. The quantitative data were analyzed by Pearson's correlation and independent t-tests (α = 0.05). In the corrosion parameters, there was a strong lipopolysaccharide correlation with the Ipass (passivation current density), Cdl (double-layer capacitance), and Rp (polarization resistance) values (p<0.05) for the Ti-6Al-4V alloy with surface treatment by double-acid-etching. The combination of dextrose and lipopolysaccharide was correlated with the Icorr (corrosion current density) and Ipass (p<0.05). The acid-treated groups showed a significant increase in Cdl values and reduced Rp values (p<0.05, t-test). According to the topography, there was an increase in surface roughness (R2 = 0.726, p<0.0001 for the smooth surface; R2 = 0.405, p = 0.036 for the double-acid-etching-treated surface). The microhardness of the smooth Ti-6Al-4V alloy decreased (p<0.05) and that of the treated Ti-6Al-4V alloy increased (p<0.0001). Atomic force microscopy showed changes in the microstructure of the Ti-6Al-4V alloy by increasing the surface thickness mainly in the group associated with dextrose and lipopolysaccharide. The combination of dextrose and lipopolysaccharide affected the corrosion behavior of the Ti-6Al-4V alloy surface treated with double-acid-etching. However, no dose-response corrosion behavior could be observed. These results suggest a greater susceptibility to corrosion of titanium implants in diabetic patients with associated infections.

Abstract
Dental patients with special needs are people with different systemic diseases, multiple disorders or severe physical and/or mental disabilities. A Medline search was made, yielding a total of 29 articles that served as the basis for this study, which offers a brief description of the dental intervention protocols in medically compromised patients. Dental treatment in patients with special needs, whether presenting medical problems or disabilities, is sometimes complex. For this reason the hospital should be regarded as the ideal setting for the care of these individuals. Before starting any dental intervention, a correct patient evaluation is needed, based on a correct anamnesis, medical records and interconsultation reports, and with due assessment of the medical risks involved. The hospital setting offers the advantage of access to electronic medical records and to data referred to any complementary tests that may have been made, and we moreover have the possibility of performing treatments under general anesthesia. In this context, ambulatory major surgery is the best approach when considering general anesthesia in patients of this kind.
Key words:Hospital dentistry, special patients, medically compromised patients.

Abstract
PURPOSE To evaluate the efficacy of plasma-rich growth factor (PRGF) in improving socket healing after tooth extraction in diabetic patients. MATERIALS AND METHODS This was a split-mouth study in which each patient also served as the control: the study socket was treated with PRGF, whereas the control socket underwent natural healing. The outcome variables were the Healing Index, residual socket volume, visual analog scale score, postsurgical complications, and outcome of a patient questionnaire. The investigation considered the impact of hyperglycemia, glycated hemoglobin, End Organ Disease Score, and smoking habits. Follow-up included 4 postextraction checkups over a 21-day period. Pairs of correlated continuous variables were analyzed with the Wilcoxon test, independent continuous variables with the Mann-Whitney test, and categorical variables with the χ(2) test or Fisher test. RESULTS From January 2012 to December 2012, 34 patients affected by insulin-dependent diabetes mellitus underwent contemporary bilateral extractions of homologous teeth. The treatment-versus-control postoperative comparison showed that PRGF resulted in significantly smaller residual socket volumes and better Healing Indices from days 3 to 14. The patients' questionnaire outcomes were unanimously in favor of PRGF treatment. The small sample of patients with glycemia values of at least 240 mg/dL showed worse Healing Index and minor socket decreases. CONCLUSION PRGF application after extraction improved the healing process in diabetic patients by accelerating socket closure (epithelialization) and tissue maturation, proving the association between PRGF use and improved wound healing in diabetic patients.

Abstract
Porphyromonas gingivalis is a Gram-negative anaerobic bacterium that colonizes the human oral cavity. It is implicated in the development of periodontitis, a chronic periodontal disease affecting half of the adult population in the USA. To survive in the oral cavity, these bacteria must colonize dental plaque biofilms in competition with other bacterial species. Long-term survival requires P. gingivalis to evade host immune responses, while simultaneously adapting to the changing physiology of the host and to alterations in the plaque biofilm. In reflection of this highly variable niche, P. gingivalis is a genetically diverse species and in this review the authors summarize genetic diversity as it relates to pathogenicity in P. gingivalis. Recent studies revealing a variety of mechanisms by which adaptive changes in genetic content can occur are also reviewed. Understanding the genetic plasticity of P. gingivalis will provide a better framework for understanding the host-microbe interactions associated with periodontal disease.

Abstract
The impact of dietary behaviors and food consumption and their relation to oral health are significant public health issues. Women and men exhibit different dietary behaviors. Understanding the influences of dietary behaviors on oral health from the perspective of gender disparities, however, is limited. This article provides the intersections of dietary factors and oral-systemic health for which women are at greater risk than men. Topics include the effect of dietary choices on oral health disparities seen in female patients. Interventional strategies at the local and community level that are designed to influence the balance between dietary habits and oral-systemic health are discussed.

Abstract
BACKGROUND People with type 2 diabetes have an increased risk of oral health problems; however, oral health is currently not included in structured diabetes reviews and education in the UK. AIM AND OBJECTIVES This study explores the patient's experience related to oral health and diabetes, especially in relation to: • Awareness of the link between oral health and diabetes and oral self-care needs. • Interaction with health professionals in dental and general practice. • Preferences for receiving oral health information and education. Methods This nested qualitative study involved semi-structured telephone interviews with a purposive sample of 20 participants from a questionnaire study on oral health awareness in patients with diabetes. Interview transcripts were analysed using a thematic framework approach. RESULTS Participants were mostly unaware of the link between oral health and diabetes. Those that had been made aware by a health professional were not given concrete self-care advice. Interactions with dental professionals were often limited to informing the dental practice of their diagnosis and current medication. Most participants were in favour of dentists screening for diabetes, but as their general practice was the hub for diabetes care, they felt GPs or nurses should provide oral health information and discuss oral health with patients. CONCLUSIONS Written information regarding diabetes and its possible effects on oral health needs to be more readily available to people with diabetes, especially at diagnosis. There may be a place for introducing a structured oral health question in routine diabetes reviews.
