Burning Mouth Syndrome Treated with Low-Level Laser and Clonazepam: A Randomized, Single-Blind Clinical Trial. Biomedicines 2024; 12:1048. [PMID: 38791010 PMCID: PMC11118462 DOI: 10.3390/biomedicines12051048] [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: 04/16/2024] [Revised: 04/30/2024] [Accepted: 05/07/2024] [Indexed: 05/26/2024] Open
Abstract
OBJECTIVE Burning mouth syndrome (BMS) is a chronic pain disorder characterized by intraoral burning or dysaesthetic sensation, with the absence of any identifiable lesions. Numerous treatments for BMS have been investigated, though without conclusive results. An analysis was conducted of the efficacy of treatment with a low-level diode laser and clonazepam in patients with BMS, and a study was carried out on the levels of different salivary biomarkers before and after treatment. MATERIAL AND METHODS A randomized, single-blind clinical trial was carried out involving 89 patients divided into the following groups: group 1 (laser, The Helbo® Theralite Laser 3D Pocket Probe + clonazepam) (n = 20), group 2 (sham laser placebo) (n = 19), group 3 (laser) (n = 21) and group 4 (clonazepam) (n = 18). Symptom intensity was scored based on a visual analogue scale (VAS). Sialometry was performed before and after treatment, and the Xerostomia Inventory, Oral Health Impact Profile-14 (OHIP-14) and Mini-Nutritional Assessment (MNA) questionnaires were administered. The following markers were measured in saliva samples: interleukins (IL2, IL4, IL5, IL6, IL7, IL8, IL1β, IL10, IL12, IL13, IL17, IL21 and IL23), proteins (MIP-3α, MIP-1α and MIP-1β), GM-CSF, interferon gamma (IFNγ), interferon-inducible T-cell alpha chemoattractant (ITAC), fractalkine and tumor necrosis factor α (TNFα). RESULTS A significant decrease in the VAS scores was observed after treatment in group 1 (laser + clonazepam) (p = 0.029) and group 3 (laser) (p = 0.005). In turn, group 3 (laser) showed a decrease in the salivary concentration of fractalkine (p = 0.025); interleukins IL12 (p = 0.048), IL17 (p = 0.020), IL21 (p = 0.008), IL7 (p = 0.001) and IL8 (p = 0.007); proteins MIP1α (p = 0.048) and MIP1β (p = 0.047); and TNFα (p = 0.047) versus baseline. Following treatment, group 1 (laser + clonazepam) showed significant differences in IL21 (p = 0.045) and IL7 (p = 0.009) versus baseline, while group 4 (clonazepam) showed significant differences in IL13 (p = 0.036), IL2 (p = 0.020) and IL4 (p = 0.001). No significant differences were recorded in group 2 (sham laser placebo). CONCLUSIONS The low-level diode laser is a good treatment option in BMS, resulting in a decrease in patient symptoms and in salivary biomarkers. However, standardization of the intervention protocols and laser intensity parameters is needed in order to draw more firm conclusions.

Naturally-Occurring Bioactives in Oral Cancer: Preclinical and Clinical Studies, Bottlenecks and Future Directions. Front Biosci (Schol Ed) 2022; 14:24. [PMID: 36137983 DOI: 10.31083/j.fbs1403024] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2022] [Revised: 07/16/2022] [Accepted: 08/01/2022] [Indexed: 06/16/2023]
Abstract
Oral cancer (OC) is the eighth most common cancer, particularly prevalent in developing countries. Current treatment includes a multidisciplinary approach, involving chemo, radio, and immunotherapy and surgery, which depends on cancer stage and location. As a result of the side effects of currently available drugs, there has been an increasing interest in the search for naturally-occurring bioactives for treating all types of cancer, including OC. Thus, this comprehensive review aims to give a holistic view on OC incidence and impact, while highlights the preclinical and clinical studies related to the use of medicinal plants for OC prevention and the recent developments in bioactive synthetic analogs towards OC management. Chemoprophylactic therapies connect the use of natural and/or synthetic molecules to suppress, inhibit or revert the transformation of oral epithelial dysplasia (DOK) into oral squamous cell carcinoma (OSCC). Novel searches have underlined the promising role of plant extracts and phytochemical compounds, such as curcumin, green tea extract, resveratrol, isothiocyanates, lycopene or genistein against this malignancy. However, poor bioavailability and lack of in vivo and clinical studies and complex pharmacokinetic profiles limit their huge potential of application. However, recent nanotechnological and related advances have shown to be promising in improving the bioavailability, absorption and efficacy of such compounds.

Proteomics-Based Identification of Salivary Changes in Patients with Burning Mouth Syndrome. BIOLOGY 2021; 10:392. [PMID: 34062870 PMCID: PMC8147377 DOI: 10.3390/biology10050392] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/26/2021] [Revised: 04/19/2021] [Accepted: 04/28/2021] [Indexed: 11/23/2022]
Abstract
Burning mouth syndrome (BMS) is a chronic oral condition characterized by an intraoral burning sensation, taste alterations, and dry mouth sensations. Although a number of factors have been closely related to the appearance of the symptoms, including anxiety, depression, and sleep disturbances, the etiology of BMS remains unclear. Furthermore, currently no objective diagnostic tools exist, making its diagnosis challenging. Therefore, to contribute to the knowledge about BMS etiology and look for objective tools for its diagnosis, the present study was conducted. Thus, the aim of this study was to analyze the proteomic profile of the resting whole saliva of patients with BMS and age and sex-matched controls using two-dimensional electrophoresis. The results showed evidence of changes in saliva at the level of proteins related to important pathways such as stress (sAA), immune system (Ig), and inflammation (leukocyte elastase inhibitor). While some of our findings have been previously described others, such as the deregulation of the coiled-coin domain containing protein 25 in BMS, are presented here for the first time to our knowledge. Thus, saliva provides us with relevant information about BMS pathophysiology and could be considered a suitable biofluid for its study and/or diagnosis.

Oral Health Status in Older People with Dementia: A Case-Control Study. J Clin Med 2021; 10:jcm10030477. [PMID: 33514062 PMCID: PMC7865865 DOI: 10.3390/jcm10030477] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2020] [Revised: 01/18/2021] [Accepted: 01/20/2021] [Indexed: 12/28/2022] Open
Abstract
Dementia is characterized by a range of cognitive defects with impaired activities of daily living that have implications for patient oral health. Objectives. A case-control study was made of the impact of dementia upon oral health. A total of 152 patients were included: 69 with dementia and 83 controls from the region of Murcia (Spain). The Global Deterioration Scale (GDS) was used to classify the patients and an oral exploration was carried out. Odds ratios (ORs) and confidence intervals (CIs) were estimated using regression models. The patients with more severe disease were significantly more likely to have fewer natural teeth (OR 11.00, 95%CI 1.28–23.22; p = 0.001), a higher plaque index (p = 0.001), and a greater bleeding index (p = 0.001) than the control group. These findings suggest that older adults with dementia have deficient oral health. A higher bleeding index increases the risk of deterioration of cognitive function. The oral hygiene and health of older people with dementia need to be improved.

Methylenetetrahydrofolate reductase C677T polymorphism is not associated with the risk of nonsyndromic cleft lip/palate: An updated meta-analysis. Sci Rep 2020; 10:1531. [PMID: 32001764 PMCID: PMC6992667 DOI: 10.1038/s41598-020-58357-0] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2019] [Accepted: 12/18/2019] [Indexed: 11/08/2022] Open
Abstract
Both genetic and environmental factors affect the risk of orofacial clefts. The present meta-analysis aimed to evaluate the association between methylenetetrahydrofolate reductase (MTHFR) C677T polymorphism and risk of nonsyndromic cleft lip/palate (NSCL/P) in cases-control studies. The PubMed/Medline, Scopus, Web of Science, and Cochrane Library databases were searched up to April 2019 with no restrictions. The odds ratios (ORs) and 95% confidence intervals (CIs) in all analyses were calculated by Review Manager 5.3 software. The funnel plot analysis was carried out by the Comprehensive Meta-Analysis version 2.0 software. Subgroup analysis, meta-regression, and sensitivity analysis were performed for the pooled analyses. Thirty-one studies reviewed in this meta-analysis included 4710 NSCL/P patients and 7271 controls. There was no significant association between MTHFR C677T polymorphism and NSCL/P susceptibility related to allelic model (OR = 1.04; P = 0.49), homozygote model (OR = 1.11; P = 0.35), heterozygote model (OR = 0.99; P = 0.91), dominant model (OR = 1.00; P = 0.96), or recessive model (OR = 1.08; P = 0.23). There was no significant association between MTHFR C677T polymorphism and NSCL/P susceptibility based on the ethnicity or the source of cases. There was a significant linear relationship between the year of publication and log ORs for the allele model. The results of the present meta-analysis failed to show an association between MTHFR C677T polymorphism and NSCL/P susceptibility. The subgroup analyses based on the ethnicity and the source of cases further confirmed this result.

Abstract
OBJECTIVES The objective of this study was to evaluate the changes that can occur in saliva components in patients with Alzheimer's disease (AD) of different severity and determine if any of these components could be a biomarker of this disease. Therefore, a panel of selected analytes related to the amyloid cascade, the immune and adrenergic systems, among others, were analyzed in the saliva of patients with Alzheimer's disease. METHODS A total of 152 patients with AD and controls were included. The severity of the disease was established according to the Global Deterioration Scale. Unstimulated whole saliva was collected. RESULTS Salivary amyloid-β42 was significantly lower, and complement C4 was significantly higher in the patients with AD than in the controls (p < 0.05 in both cases). Only complement C4 maintained its significant effect in the multivariate regression analysis. However, the area under the receiver operating characteristic curve of C4 was 0.613. No changes were found in any analyte regarding the severity of the disease. CONCLUSIONS A decrease in amyloid-β42 and an increase in complement C4 were detected in the saliva of patients with AD, but the changes did not show a high diagnostic performance for the detection of AD and were not associated with its severity. CLINICAL RELEVANCE Although some analytes showed significant differences in saliva in patients with AD, in our study conditions the salivary biomarkers analyzed were not of enough diagnostic utility for being used in routine.

Abstract
OBJECTIVE Non-syndromic cleft lip/palate (NSCL/P) has a multifactorial and polygenic aetiology. The role of genetics in its occurrence has not been fully clarified. The present meta-analysis aimed to evaluate the association of betaine-homocysteine S-methyltransferase (BHMT) polymorphisms (rs3797546 and rs3733890) with the risk of NSCL/P. MATERIALS AND METHODS PubMed/Medline, Scopus, Cochrane Library, and Web of Science databases were systematically searched for articles published up until December 2018 with no language restriction. Quality evaluation of each study was performed by the Newcastle-Ottawa Scale (NOS). The crude odds ratio (OR) and 95% confidence interval (CI) were calculated for each study by RevMan 5.3 software, and a funnel plot analysis was performed by the CMA 2.0 software using the Egger's and Begg's tests. RESULTS Review of the four selected studies revealed that the CC genotype of rs3797546 polymorphism significantly increased the risk of NSCL/P. No association was noted between NSCL/P risk and rs3733890 polymorphism except in Chinese (elevated risk of NSCL/P) and Polish (decreased risk of NSCL/P) populations. CONCLUSIONS According to the present meta-analysis, rs3733890 polymorphism does not play a role in susceptibility to NSCL/P; whereas, rs3797546 polymorphism may play a role in susceptibility to NSCL/P. Future studies are required to examine the association between BHMT polymorphisms and the NSCL/P risk in different ethnicities with a larger sample size.

Abstract
INTRODUCTION Several environmental and genetic factors have a role in the aetiology of non-syndromic cleft lip/palate (NSCL/P). This meta-analysis evaluated the association of rs3758249 and rs4460498 forkhead box E1 (FOXE1) polymorphisms with the NSCL/P risk. MATERIALS AND METHODS The Scopus, Cochrane Library, Web of Science, and PubMed databases were searched for articles published until March 2019. The analyses were performed by Review Manager 5.3 using the crude odds ratio (OR) and 95% confidence interval (CI) for a strong association between FOXE1 polymorphisms and the risk of NSCL/P. RESULTS Out of 161 articles retrieved from the databases, four case-control articles were involved in the meta-analysis. The pooled ORs of rs4460498 polymorphism based on allelic, homozygous, heterozygous, dominant, and recessive models were 0.74 (95% CI: 0.69, 0.80; P<0.00001), 0.43 (95% CI: 0.30, 0.61; P<0.00001), 0.66 (95% CI: 0.55, 0.80; P<0.0001), 0.66 (95% CI: 0.59, 0.73; P<0.00001), and 0.70 (95% CI: 0.60, 0.82; P<0.0001), respectively; whereas, the pooled OR of rs3758249 polymorphism were 0.86 (95% CI: 0.71, 1.04; P=0.12), 0.68 (95% CI: 0.57, 0.82; P<0.0001), 0.79 (95% CI: 0.57, 1.09; P=0.15), 0.79 (95% CI: 0.58, 1.08; P=0.14), and 0.80 (95% CI: 0.68, 0.95; P=0.010) for the afore-mentioned models, respectively. CONCLUSIONS The results showed that the T allele, TT, and CT genotypes of rs4460498 polymorphism were significantly associated with a decreased risk of NSCL/P; whereas, for rs3758249 polymorphism, only the AA genotype had a significant protective role in NSCL/P. Thus, FOXE1 is strongly associated with NSCL/P in the populations.

Abstract
Background and Objectives: Interferon-gamma (IFN-γ)/interleukin-4 (IL-4) ratio may indicate a change in the immune response with a potential pathological effect presented in oral lichen planus (OLP) patients. Herein, this meta-analysis evaluated the role of serum and salivary interferon-gamma/interleukin-4 ratio in the severity and development of OLP. Materials and Methods: The Scopus, Cochrane Library, PubMed, and Web of Science databases were systematically searched to retrieve the relevant studies published up from the database inception to March 2019. The crude mean difference (MD) and 95% confidence interval (CI) were calculated by RevMan 5.3 software using a random-effects model. A sensitivity analysis was performed on the results using the CMA 2.0 software. A total of 98 studies were retrieved from the databases, of which at last seven studies were included in this meta-analysis. Results: The findings showed that the pooled MDs of serum and salivary IFN-γ/IL-4 ratio were −0.22 (95% CI: −1.16, 0.72; p = 0.64) and 0.17 (95% CI: −1.50, 1.84; p = 0.84) in OLP patients compared to controls, respectively. In addition, the pooled MDs of serum and salivary IFN-γ/IL-4 ratio were −0.15 (95% CI: −0.53, 0.23; p = 0.43) and −0.39 (95% CI: −0.63, −0.15; p = 0.001) in patients with erythematous/ulcerative subtype compared to patients with reticular subtype, respectively. Conclusions: In conclusion, the results of meta-analysis demonstrated that serum and salivary IFN-γ/IL-4 ratio cannot play a major role in OLP development and severity.

Abstract
Background and objective: Cortisol, as the main human glucocorticoid, is considered to be a biological marker of stress and anxiety. Since it is known that oral lichen planus (OLP) can appear and worsen during stressful events, cortisol levels have been previously studied in OLP patients. The present meta-analysis aims to assess the salivary concentration of cortisol in OLP patients compared to healthy controls. Materials and methods: Web of Science, PubMed, Cochrane Library, and Scopus databases were searched up to October 2018. The RevMan 5.3 software was used with the mean difference (MD) and 95% confidence intervals (CIs). The CMA 2.0 Software was used to evaluate the publication bias, sensitivity analysis, and meta-regression as possible sources of heterogeneity. Results: 10 studies were analyzed and a total of 269 OLP patients and 268 controls were included. The pooled MD of the salivary levels of cortisol in OLP patients compared with controls was 4.27 ng/mL (95% CI: 2.33, 6.21; P < 0.0001), thus, the salivary level of cortisol in OLP patients was significantly higher than in controls. In Indian-based population studies, a significant difference in the salivary cortisol levels in OLP patients compared with controls was detected (MD = 5.62 ng/mL; 95% CI: 2.67, 8.56; P = 0.0002). In addition, a significant difference in the salivary cortisol levels in the OLP patients compared with the controls was obtained in studies performed with enzyme-linked immunosorbent assay (ELISA) method (MD = 5.33 ng/mL; 95% CI: 2.72, 7.93; P < 0.0001). Conclusion: We suggest that supportive psychological treatment together with the conventional therapy could increase patients' capability to prevent stress, anxiety, and depression.

Abstract
Oral mucosal lesions have many etiologies, including viral or bacterial infections, local trauma or irritation, systemic disorders, and even excessive alcohol and tobacco consumption. Folk knowledge on medicinal plants and phytochemicals in the treatment of oral mucosal lesions has gained special attention among the scientific community. Thus, this review aims to provide a brief overview on the traditional knowledge of plants in the treatment of oral mucosal lesions. This review was carried out consulting reports between 2008 and 2018 of PubMed (Medline), Web of Science, Embase, Scopus, Cochrane Database, Science Direct, and Google Scholar. The chosen keywords were plant, phytochemical, oral mucosa, leukoplakia, oral lichen planus and oral health. A special emphasis was given to certain plants (e.g., chamomile, Aloe vera, green tea, and coffea) and plant-derived bioactives (e.g., curcumin, lycopene) with anti-oral mucosal lesion activity. Finally, preclinical (in vitro and in vivo) and clinical studies examining both the safety and efficacy of medicinal plants and their derived phytochemicals were also carefully addressed.

Abstract
The main objective was to assess the efficacy of botulinum toxin-based treatment for sialorrhea in adult patients with Parkinson's disease. The search was performed by using the Medline-PubMed, EMBASE and Cochrane Library databases from January 2000⁻December 2017, in English/Spanish in patients with Parkinson's disease and sialorrhea. The methodological quality of trials was carried out by following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) criteria and the Newcastle⁻Ottawa Scale (NOS). Finally, a total of 21 articles were identified as fulfilling the inclusion criteria. There is no consensus regarding the site of injection of the toxin (single or multiple points), toxin dose or follow-up period. In all cases there was a reduction of sialorrhea. Treatment safety increases with the use of ultrasonography. Effects approximately occur at one week post-injection and for 3⁻5 months. Botulinum toxin is an effective therapeutic strategy or option in treating sialorrhea in adult patients with Parkinson's disease. More studies with a better design, larger samples and a longer follow-up period are required to confirm these data.

Abstract
OBJECTIVE Cytokines have regulatory and leading roles in the immunopathogenesis of oral lichen planus (OLP). Here, we present the findings of a meta-analysis that evaluated serum and salivary interferon-γ (IFN-γ) levels in patients with OLP compared with those in controls and the correlation of this cytokine with the progression of OLP. STUDY DESIGN Four databases-PubMed, Web of Science, Scopus, and Cochrane Library-were searched, from their start dates to November 2017, for reports in all languages on the effect of OLP on salivary and serum IFN-γ. RESULTS Eleven studies were included and analyzed in this meta-analysis. The pooled mean difference (MD) values were estimated to be 3.60 pg/mL (P = .23) and -0.02 pg/mL (P = 1.00) for serum and salivary levels of IFN-γ, respectively, in the patients with OLP compared with controls. The pooled MD values were -2.52 pg/mL (P = .03) and -2.01 pg/mL (P = .20) for serum and salivary IFN-γ levels in the erosive type, respectively, compared with the nonerosive type. CONCLUSIONS According to the results of meta-analysis, there was no statistically significant differences in IFN-γ levels between the OLP group and the control group both in serum and salivary levels and also between erosive and nonerosive types of OLP at the salivary level; so this cytokine is not considered to have an important role in the pathogenesis or severity of OLP.

Obesity is a common nutrition-related disorder leading to reduced life expectancy in both humans and dogs. With the aim of identifying new prevention and control options, the study objectives were (1) to investigate dog-owner perceptions about obesity in terms of themselves and their dogs, and (2) to identify factors associated with obesity and possible social, environmental and economic drivers for its development in dog owners and their pets. A cross-sectional questionnaire-based study was performed across multiple countries. The questionnaire focused on human and canine obesity, associated factors and potential drivers, and was distributed online and in the form of hard copies among dog owners in 11 European countries. In total, 3,185 responses from ten countries were included in multivariable analyses. Between 19.1% and 48.8% of the dog owners reported to be overweight/obese. Owner-reported overweight/obesity in dogs ranged from 6.0% to 31.3% based on body condition score charts, and 31.8% to 69.4% based on body fat index charts. Common factors associated with obesity in owners and their dogs were age, gender and owners' attitudes to diet and physical activity. Dog owners who did not consider obesity to be a disease were more likely to have obese dogs.

Application of the NEOH Framework for Self-Evaluation of One Health Elements of a Case-Study on Obesity in European Dogs and Dog-Owners. Front Vet Sci 2018; 5:163. [PMID: 30083538 PMCID: PMC6064947 DOI: 10.3389/fvets.2018.00163] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2017] [Accepted: 06/28/2018] [Indexed: 11/13/2022] Open
Abstract
Obesity is a malnutrition disorder of global concern with increasing prevalence driven by underlying societal, economic and environmental mechanisms leading to changed physical activity patterns, eating behaviors and diet compositions in both humans and in their pet-dogs. A questionnaire-based study was carried out as a joint effort across 11 European countries. It was considered a One Health (OH) initiative between scientists from human and animal health sectors aiming to identify factors associated with obesity in dog owners and their dogs. Expected outcomes of this approach included new insights unachievable by single-sector research initiatives, and hence potentially leading to new cross-sectorial solutions. We performed an internal evaluation among the actors of the obesity initiative using the framework for evaluation developed by the “Network for Evaluation of One Health” (NEOH). It served as a case-study for the NEOH consortium to illustrate the application and provide feedback on the utility of the framework. The evaluation was performed by a subgroup of scientists also involved in the obesity study group, and it consisted of: (1) the definition of the initiative and its context, (2) the description of the theory of change, and (3) the qualitative and quantitative process evaluation of operations and supporting infrastructures scored on a scale from 0 to 1. In the One Health operations, the obesity study initiative scored medium high on OH-thinking (0.5) and OH-planning (0.45), and relatively high on OH-working (0.7). The supporting infrastructure score was high for systemic organization (0.8), but low for sharing (0.45) and learning (0.28). The calculated OH-index was 0.29 (on scale 0 to 1) indicating that the full potential of health integration and collaboration was not exploited in the initiative, and the main issue identified was a lack of stakeholder engagement. The OH-ratio of 1.1 indicated equal focus on operations and supporting infrastructures. Hence, the evaluation identified potentially counterproductive as well as beneficial characteristics, which are further discussed in this paper in relation to the expected outcomes. The NEOH framework for evaluation requires that the evaluators have a good understanding of systems thinking and the mechanisms of the health issue targeted by the initiative.

Abstract
OBJECTIVES To evaluate salivary adiponectin and adenosine deaminase (ADA) in women suffering from Sjögren's syndrome (SS). METHODS Salivary adiponectin and ADA were measured in patients with SS (n = 17) and compared to their values in healthy controls (n = 13) and patients suffering from drug-induced xerostomia (non-SS sicca group; n = 19). A clinical history was made for each patient, patients were examined clinically, and xerostomia inventory (XI) was performed. RESULTS Salivary adiponectin corrected by total protein was higher in patients with SS than in healthy individuals (P < 0.05) or patients with non-SS sicca (P < 0.01) and correlated with XI (r = 0.555; P < 0.05). Salivary ADA was higher in patients with SS and non-SS sicca compared to controls (P < 0.05 in both cases). CONCLUSION The results of the present study indicate that adiponectin and ADA are increased in the saliva of patients with SS. CLINICAL RELEVANCE Salivary adiponectin corrected by total protein can be a potential biomarker of SS. TRIAL REGISTRATION NCT03156569.

A Proteomic Analysis of the Virulence Factors of Three Common Bacterial Species Involved in Periodontitis and Consequent Possible Atherosclerosis: A Narrative Review. Curr Protein Pept Sci 2018; 19:1124-1130.

Abstract
The incidence of cardiovascular disorders, especially coronary artery disease and atherosclerosis, is increasing alarmingly. Clarifying the underlying causes is of the utmost importance and should be elucidated in order to reduce this growing trend. Periodontitis is known as a chronic destructive disease with sophisticated pathophysiological mechanisms that slowly impose negative effects not only on the oral tissues but also on distant organs. Additionally, it has been shown in many studies that atherosclerosis and periodontitis utilized common inflammatory signaling pathways and mediators. Several lines of evidence have demonstrated the signatures of periodontitis-related bacteria in atherosclerotic plaque specimens. It is proposed that virulent proteins of these bacteria probably accelerate the initiation or development of plaque formation on the inner walls of the coronary arteries. Proteomics techniques are very sensitive and have a global point of view. They can help to discover host factors and pathogenrelated biomarkers. This review summarizes the studies focused on the three most important bacterial species involved in both diseases and presents recent findings about the proteomic evaluation of virulence factors of these bacteria. The known mechanisms of action of the virulence factors are also described.

Abstract
Objective This study set out to identify the neuropathic component of pain experienced by burning mouth syndrome (BMS) patients evaluated using painDETECT, a diagnostic tool that could easily be introduced into clinical practice. Materials and Methods This study included 64 patients (33 BMS and 31 suffering nociceptive pain). Each completed the painDETECT neuropathic pain questionnaire, the Hospital Anxiety and Depression Scale, and pain intensity was also measured using a visual analogue scale (VAS). Results Pain among BMS patients (evaluated by VAS) was 6.1 ± 1.9, and 4.3 ± 1.7 among nociceptive patients ( P < 0.001). PainDETECT obtained total scores ≥ 19 in 21% of BMS patients, indicating the presence of neuropathic pain. When painDETECT pain descriptors were analyzed comparing the BMS group with nociceptive pain subjects, statistically significant differences were found for burning sensation ( P < 0.010), prickling ( P < 0.001), electric shock-like sensation ( P = 0.046), thermal sensation ( P < 0.001), and numbness ( P = 0.002). Logistic regression analysis found that VAS scoring was the strongest determinant predicting neuropathic pain. Conclusion The present study suggests that almost a third of BMS patients present neuropathic pain, which is strongly associated with the intensity of pain measured using VAS. These data could provide the basis for further research.

Abstract
OBJECTIVE The aim of this study was to determine the presence of periodontal disease among patients with rheumatoid arthritis (RA) in comparison with a control group. METHOD AND MATERIALS The study included 44 patients diagnosed with RA according to American Rheumatism Association (ARA) criteria, who were attending the Morales Meseguer Hospital Rheumatology Service (Murcia, Spain), and 41 control subjects. Patients younger than 18 years or patients suffering systemic diseases that could affect the immune system were excluded. Age, sex, smoking habits, alcohol consumption, and body mass index were registered. Each patient underwent a full periodontal examination. RESULTS Bleeding on probing was significantly greater in the RA group (0.9 ± 0.36) than the control (P < .001). The Plaque Index was significantly higher in the RA group (0.76 ± 0.34) versus the control group (0.55 ± 0.2) (P < .001). RA patients showed a 0.13 increased risk of periodontal disease (95% confidence interval, 0.05-0.37). CONCLUSION Patients with RA suffered a higher risk of periodontal disease and for this reason these patients must be instructed to intensify their oral hygiene regimes.

Abstract
To investigate low-level laser therapy (LLLT) applied to treat burning mouth syndrome (BMS). This prospective, comparative, partially blinded, single-centre, clinical trial of GaAlAs Laser, with 815 nm wavelength, included 44 BMS patients divided randomly into three groups: Group I (n = 16): GaAlAs laser 815 nm wavelength, 1 W output power, continuous emissions, 4 s, 4 J and fluence rate 133·3 J cm-2 ; Group II (n = 16): GaAlAs infrared laser, 815 nm wavelength, 1 W output power, continuous emissions, 6 s, 6 J and fluence rate 200 J cm-2 ; Group III (n = 12) placebo group, sham laser. All groups received a weekly dose for 4 weeks. Pain intensity was recorded using a 10-cm visual analogue scale; patients responded to the oral health impact profile (OHIP-14), xerostomia severity test and the hospital anxiety-depression scale (HAD). These assessments were performed at baseline, 2 and 4 weeks. LLLT decreased pain intensity and improved OHIP-14 scores significantly from baseline to 2 weeks in groups I and II compared with the placebo group. No statistically significant differences were found from 2 to 4 weeks. Overall improvements in visual analogue scale (VAS) scores from baseline to the end of treatment were as follows: Group I 15·7%; Group II 15·6%; Group III placebo 7·3%. LLLT application reduces symptoms slightly in BMS patients.

Abstract
OBJECTIVE Oral mucositis (OM) is a common complication of chemotherapy and radiotherapy. The aim of this study was to evaluate the effects of treating 5-fluorouracil-induced OM with apigenin and dexamethasone. METHODS Thirty-six male Syrian hamsters were randomly assigned to one of three groups: control (50% acetic acid + 5-FU), 50% acetic acid + 5-FU + potassium Apigenin (KA), and 50% acetic acid + 5-FU + dexamethasone. The animals from each group were sacrificed 5, 7, 10, and 14 days after inducing the mucositis, and two samples collected from each animal, accounting a total of 72 samples. Macroscopic changes were assessed by histomorphometric analysis, with ulcers being assessed by imaging analysis and the number of inflammatory cells in the ulcerated region quantified in all periods through histomorphometric analysis (H&E). Furthermore, immunohistochemical changes were evaluated by proliferating cell nuclear antigen. RESULTS All groups presented an increased inflammatory infiltrate after 7 days, compared to other evaluation times (P ≥ 0.05). There was significant difference between apigenin and control group in the 10-days period. Lower quantity of inflammatory cells in the apigenin-treated group in comparison with control group in the 7- and 10-days periods was observed (P < 0.05). No statistically significant difference was verified among the groups in 5- and 14-days periods. The healing process of the control group was slower than that of apigenin and dexamethasone-treated groups, with an overall significant difference between apigenin and the control group in the 10-days period. CONCLUSIONS Apigenin treatment may enhance healing of OM induced by 5-fluorouracil, thus suggesting that more extensive research in this area may be useful to assess the role of agents of natural origin capable of preventing OM. Hence, further studies involving broader samples are need to confirm the therapeutic potential shown by this study.

Abstract
PURPOSE To date, no ideal strategy has been established for treating or preventing medication-related osteonecrosis of the jaw (MRONJ). The aim of the present work was to perform a systematic literature review to determine the efficacy of autologous platelet concentrate (APC) application, for prevention or treatment of MRONJ, together with surgical debridement. MATERIAL AND METHODS An electronic search was performed using MEDLINE (PubMed), EMBASE, and Cochrane databases until January 2015 using the following search terms: osteonecrosis, bisphosphonates, antiresorptive, antiangiogenic therapy, BRONJ, platelet concentrate, PRP, PRF, and PRGF. Two reviewers assessed the eligibility of articles independently and extracted key data. The methodology used met PRISMA criteria. The Newcastle-Ottawa scale was used to assess the quality of the articles. RESULTS Preventive applications of platelet-rich plasma (PLP) were reported in 697 dental extractions in patients taking bisphosphonates intravenously, of whom seven patients developed osteonecrosis (five mandibular and two maxillary). In cases of established osteonecrosis, eight studies reported treatment by surgery combined with APC (seven with PRP and one with leukocyte-rich and platelet-rich fibrin) in 123 patients (34 men and 89 women) with ONJ, who received 157 treatments, of which 135 achieved complete resolution (85.98%). CONCLUSION There are no published scientific data to sufficiently support any specific treatment protocol, including the use of APC together with surgical debridement, for the management of MRONJ. Randomized controlled clinical trials of the use of APC are needed.

Abstract
Radiotherapy effectively treats cancers of the head and neck. We investigated the possible protective effects of lycopene and curcumin on the parotid glands of 40 female Sprague Dawley rats during irradiation. The study followed European Union regulations 86/609/EEC, 2010/63/EU for animal experimentation. The animals were divided into 4 groups: those treated with curcumin and radiation, those treated with lycopene and radiation, those treated with dimethyl sulphoxide (DMSO) and radiation, and those treated with radiation alone. All compounds were given intraperitoneally the day before irradiation. The total dose of radiation was 20Gy. Morphological and histopathological analyses showed less cell necrosis in the group treated with curcumin than in the other groups, but the difference was not significant. Analysis of structural damage to the parotid ducts and vacuolisation showed significant differences among all groups (p=0.023, p<0.01). Lycopene and curcumin given 24 hours before irradiation reduced the structural damage to the salivary glands. Further studies are needed to confirm these findings.

Objectives To investigate sleep quality, anxiety/depression and quality-of-life in patients with xerostomia. Materials and methods This prospective, observational, cross-sectional study was conducted among a group of xerostomia patients (n = 30) compared with 30 matched control subjects. The following evaluation scales were used to assess the psychological profile of each patient: the Hospital Anxiety and Depression Scale, the Oral Health Impact Profile-14 (OHIP-14), the Xerostomia Inventory, the Pittsburgh Sleep Quality Index (PSQI) and the Epworth Sleepiness Scale (ESS). Results The PSQI obtained 5.3 3 ± 1.78 for patients with xerostomia compared with 4.26 ± 1.01 for control subjects (p = 0.006); ESS obtained 5.7 ± 2.1 for test patients vs 4.4 0 ± 1 for control subjects (p = 0.010). Statistical regression analysis showed that xerostomia was significantly associated with depression (p = 0.027). Conclusions Patients with xerostomia exhibited significant decreases in sleep quality compared with control subjects.

Abstract
BACKGROUND Oral lichen planus (OLP) is a chronic mucocutaneous disease, inflammatory and autoimmune in character, in which the pathogenesis is not fully understood. Psychological stress has also been implicated in triggering or exacerbating the disease. OBJECTIVE The aim of this study was to evaluate the psychological profile, sleep, and salivary biological markers-cortisol, immunoglobin A (IgA), and adiponectin - in patients with oral lichen planus (OLP). METHODS The sample consisted of 65 patients (33 with OLP and 32 control patients). Patients completed hospital anxiety and depression scales (HADD, HADA). Questionnaires were used to assess sleepiness: the Pittsburgh sleep quality index (PSQI) and the Epworth sleepiness scale (ESS). A visual analog scale (VAS) was used for rating pain. Unstimulated whole saliva was evaluated, together with total proteins: cortisol, IgA, and adiponectin. RESULTS Patients with OLP obtained significantly higher HADA and PSQI scores than control subjects (P = 0.001, P = 0.012, respectively). Total salivary protein (flow at rest) analysis found that total proteins were higher in the OLP group (P = 0.001). In the OLP group, IgA was 80.3 ± 51.3 vs. the control group 48.9 ± 32.8 (P = 0.005). Mean cortisol was 0.5 ± 0.3 μg/dl in the OLP group vs. 0.4 ± 0.2 μg/dl in the control group (P = 0.010). The OLP group showed a correlation between the HADA variable and pain (r = 0.358; P = 0.041), HADD (r = 0.568; P = 0.001), and PSQI (r = 0.537; P = 0.001). CONCLUSIONS OLP patients presented worse psychological profiles and sleep disturbances, as well as higher values for IgA, cortisol, and total proteins than control subjects.

Abstract
OBJECTIVE To evaluate the effects of resveratrol and irradiation on oral squamous cell carcinoma (OSCC). MATERIALS AND METHODS Resveratrol was administered at doses of 5, 10, 25, 50 and 100 µM to PE/CA-PJ15 (OSCC) cultures irradiated with different doses (1, 2.5 and 5 Gy). Effects upon cell viability, apoptosis and migration were evaluated after 24, 48 and 72 h incubation. RESULTS After 72 h of incubation, the 100 µM dose of resveratrol induced the greatest decrease in cell viability at all irradiation doses. After 24, 48 and 72 h of incubation, 100 µM of resveratrol induced the greatest cell apoptosis at all irradiation doses. The greatest alterations in the distribution of the G0-G1, G2-M and S phases of the cell cycle were recorded with 50 and 100 µM of resveratrol; after 24, 48 and 72 h of incubation, both these doses resulted in an increase in the S phase, at the expense of the G0-G1 and G2-M phases. CONCLUSIONS Resveratrol increases cytotoxic activity in the PE/CA-PJ15 cell line and reduces cell migration capacity, while the combination of resveratrol and irradiation exerts a synergic effect.

Abstract
OBJECTIVES The aim of this study was to evaluate DNA damage and cytokinetic defects, proliferative potential and cell death caused by the frequent use of mouthrinses containing chlorhexidine, triclosan and essential oils in ethanolic solution, compared to a placebo mouthwash. STUDY DESIGN This double-blind, prospective, randomized clinical trial included 80 Caucasian patients. Subjects were divided into four groups: Group I used a mouthrinse, Triclosan; Group II used physiological saline; Group III used chlorhexidine; Group IV a mouthrinse with essential oils in ethanolic solution. All subjects used the mouthrinses for two weeks (15 ml, twice a day, rinsing for 30s). Two cell samples per subject were collected, before and after mouthrinse use (on day 0 and day 15). Samples were processed as follows: cell collection from cheeks with a cytobrush; cell centrifuge; slide preparation, fixation and staining; and fluorescent microscope analysis. 2000 exfoliated cells were screened for nuclear abnormalities, particularly the presence of micronuclei by means of cytome assay. RESULTS No significant differences between study times (before and after use of mouthwash) were identified for any of the variables studied (p>0.05). Differences between mouthrinse groups were also compared but no significant differences were found (p>0.05). CONCLUSIONS This study did not observe any genotoxic effect resulting from mouthrinse use.

Abstract
AIM Lichen planus is a T cell-mediated chronic inflammatory disease of unknown etiology. The objective of the present study was to evaluate the status of oxidative stress in saliva and the anti-oxidant defense system in relation to quality of life parameters in patients with oral lichen planus (OLP). METHODS The sample consisted of 70 patients (40 with OLP and 30 control patients). The average age of OLP patients was 60 years (9 males and 31 females), and of the control group 57 years (6 males and 24 females). All participants completed the Oral Health Impact Profile-49 quality of life questionnaire. Total anti-oxidant activity and lipid peroxidation products in saliva were evaluated, using ferric reducing anti-oxidant power and thiobarbituric acid reactive substance. RESULTS Mean levels of salivary malondialdehyde were higher in the OLP group than the control group (P = 0.001), and total anti-oxidant capacity was lower among OLP patients than control patients (P = 0.02). There was no correlation between Oral Health Impact Profile-49 findings and the oxidative stress parameters studied. CONCLUSIONS The results of the present study point to the possible function of oxidative stress in the etiopathogenesis of OLP.

METHODS A total of 186 adults were consecutively recruited: 92 subjects with RAS (28 males and 64 females, with a mean age of 41 years) and 94 controls (20 men and 74 women, with a mean age of 44 years), and subjected to clinical and hematological evaluation. RESULTS The overall frequency of hematinic deficiencies was 14.14% in the RAS group versus 6.39% in the control group (P = 0.086). Patient age and a family history of aphthosis were associated to the presence of RAS. CONCLUSION There is still no conclusive evidence relevant to the etiopathogenesis of RAS. Routine hematological screening and tests for serum iron, folic acid, and vitamin B12 deficiencies should be assessed in all patients with RAS.

Abstract
Keratocystic odontogenic tumor is an intraosseous benign tumor of epithelial origin that can appear as a unicystic or multicystic lesion. It is characterized most significantly by its high recurrence rate. This is why surgical removal is the chosen therapeutic approach in most cases. However, while surgery may be the safest technique to prevent recidivism, it may also result in numerous complications with large tumors. A number of authors have suggested a more conservative treatment for large keratocystic odontogenic tumors. The case examined in this article is that of a 48-year-old male patient who presented with a five-month swelling on the left side of his face, located in the mandibular area.

Effects of potassium apigenin and verbena extract on the wound healing process of SKH-1 mouse skin. Int Wound J 2012; 11:489-95. [PMID: 23136845 DOI: 10.1111/j.1742-481x.2012.01114.x] [Citation(s) in RCA: 25] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/10/2012] [Revised: 09/19/2012] [Accepted: 10/02/2012] [Indexed: 11/27/2022] Open
Abstract
Tissue repair is a complex process, which may be favoured or inhibited by different factors. Potassium apigenin (AP) and other flavonoids present in verbena extract (PLX(®) ) possess powerful anti-inflammatory properties. The aim of this study was to evaluate the effects of topical treatment with AP and PLX gels on wounds inflicted on SKH-1/CRL mice. Forty-eight SKH-1 mice were used (4 groups with 12 animals each), which were subjected to wound excision with a round scalpel, 4 mm in diameter, on the dorsal skin. The animals were divided into four groups: Group I received topical applications of apigenin gel; Group II received PLX gel; Group III received vehicle gel; Group IV acted as control. Wound contraction, reepithelialisation, inflammation and neovascularisation (by means of immunohistochemical staining with anti-laminin) were recorded at study periods established at 2, 7 and 14 days. Reepithelialisation was faster in Groups I and II at 7 days (56·25% grade 3 and 43·75% grade 4) compared with the other groups. The degree of inflammation showed improvement with a tendency towards statistical significance in Groups I and II at 2 and 7 days. Anti-laminin staining was more intense in the group treated with PLX at the 2- and 7-day periods. Topical treatment with PLX gel improved the degree of reepithelialisation and inflammation, and favoured neo-vascularisation of the wounds at 2 and 7 days following surgery.

Abstract
AIM To determine the risk of malnutrition in both institutionalized and non-institutionalized elderly people of the region of Murcia in Spain. METHODS A cross-sectional study was carried out on 465 participants (213 men and 252 women) aged 65 years or older, and representative of the population of the region of Murcia in Spain. The nutritional condition was determined with the Mini Nutritional Assessment screening tool. The following clinical oral health variables were recorded: number of teeth in the mouth, use of removable dentures and hygiene. RESULTS The prevalence of malnutrition was 7% in the study population, whereas the risk of malnutrition was 49%. A greater prevalence was recorded in the older and in the institutionalized participants. There were no significant differences in terms of malnutrition or the risk of malnutrition between the participants with or without dentures or between the dentate or edentulous participants. CONCLUSIONS Age and institutionalization are parameters to be taken into account for detecting the risk of malnutrition in elderly people.

Abstract
Pyodermatitis-pyostomatitis vegetans (PV), a rare disorder of the skin and oral mucosa, is considered a highly specific marker for inflammatory bowel disease, especially ulcerative colitis. We have presented the case of a patient with PV. This report emphasizes the relationship of PV to inflammatory bowel disease and the importance of the oral lesions as initial presenting signs of systemic disease or activity.
