Abstract
OBJECTIVES Longitudinal assessment of the role of specific proteins on radiotherapy caries (RC) onset in head and neck cancer patients(HNC) up to one-year post-IMRT using a 5000ppm fluoride paste daily. MATERIALS AND METHODS Dental status/salivary protein data were obtained from 40 HNC patients pre-IMRT, six months (T1) and 12 months (T2) post-IMRT (ethical approval/consent). DMFT/salivary parameters were quantified, including flow rate, mucin 5B/7, Immunoglobulin A (IgA), cystatin S and α-amylase. RESULTS 45% patients had at least one carious lesion at T2, a significant reduction in the number of remaining teeth (65% <21), salivary flow rate (< 50%) and, protein secretion (< 0.05) post-IMRT. T1 IgA concentration/secretion rate was associated with RC (p < 0.05). Finally, IgA and total protein concentration obtained at T1 could provide a predictive pattern (AUC 82.3%) for the patients more predisposed to developing RC at T2. CONCLUSIONS This study demonstrated the significant association of RC with salivary proteins in HNC patients treated with IMRT, revealing the potential role of salivary proteins in the early diagnosis of RC. CLINICAL RELEVANCE This research contributes to revealing salivary proteins association with RC, and its role in early diagnosis. Therefore, this could be the first step towards personalized medicine approaches to improve this group quality-of-life.

Relationships between oral function, dietary intake and nutritional status in older adults aged 75 years and above: a cross-sectional study. BMC Public Health 2024; 24:1465. [PMID: 38822295 PMCID: PMC11143706 DOI: 10.1186/s12889-024-18906-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2023] [Accepted: 05/21/2024] [Indexed: 06/02/2024] Open
Abstract
BACKGROUND Malnutrition is related to impaired oral health and function that causes poor dietary intake, declining the general health of older adults. The role of dietary intake in the association between oral function and nutritional status of Chinese older adults (aged 75 and above) was examined in this cross-sectional study. METHODS Through the randomized cluster sampling method, 267 older adults living in rural areas of Qingdao, Shandong (aged 81.4 ± 4.3, 75-94 years) were chosen as the primary research participants. A Mini Nutritional Assessment - Short Form was used to determine nutritional status, and Food Frequency Questionnaire and 24-hour Food Intake Recall were used to assess dietary intake. The oral function was evaluated by analyzing the teeth, oral problems, bite force, tongue pressure, lip sealing pressure, chewing function questionnaire, whole saliva flow rate, 10-Item Eating Assessment Tool, and water swallow test. RESULTS Based on the MNA-SF score, it was divided into a well-nourished group and a malnutrition group, with the malnutrition group comprising 40.6% of participants. The participants in the malnutrition group showed a higher rate of xerostomia, lower bite force, tongue pressure, and lip sealing pressure, and higher Chewing Function Questionnaire and 10-Item Eating Assessment Tool scores. Furthermore, their plant fat, iron, cereals and potatoes, vegetables, fruits, and seafood intake were relatively low. The regression model indicated that exercise frequency, stroke, chewing and swallowing function, intake of vegetables and fruits were risk factors for nutritional status of older adults. CONCLUSION Malnutrition was relatively common among the Chinese older adults aged 75 and above, and it was significantly correlated with exercise frequency, stroke, chewing and swallowing function, and intake of vegetables and fruits. Therefore, nutrition management should be carried out under the understanding and guidance of the oral function and dietary intake of the older adults.

The influence of oral cavity physiological parameters: temperature, pH, and swelling on the performance of denture adhesives - in vitro study. BMC Oral Health 2024; 24:206. [PMID: 38336698 PMCID: PMC10858572 DOI: 10.1186/s12903-024-03967-7] [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: 10/13/2023] [Accepted: 02/01/2024] [Indexed: 02/12/2024] Open
Abstract
BACKGROUND The various physical and chemical conditions within the oral cavity are hypothesized to have a significant influence on the behavior of denture adhesives and therefore the overall comfort of denture wearers. As such, this study aims to understand the influence of oral cavity physiological parameters such as temperature (17 to 52 °C), pH (2, 7, 10), and denture adhesive swelling due to saliva (20-120%) on the behavior of denture adhesives. This study further aims to emphasize the need for a collective approach to modelling the in-situ behavior of denture adhesives. METHODS Rheological measurements were carried out using the Super Polygrip Ultra fresh brand denture adhesive cream to evaluate its storage modulus (G´) and loss modulus (G´´) values at a range of physiologically relevant temperatures, pH values, and degrees of swelling, to represent and characterize the wide variety of conditions that occur within the oral cavity. RESULTS Rheological data was recorded with respect to variation of temperature, pH, and swelling. Overall, it can be seen that the physiological conditions of the oral cavity have an influence on the rheological properties of the denture adhesive cream. Specifically, our data indicates that the adhesive's mechanical properties are weakly influenced by pH, but do change with respect to the temperature in the oral cavity and the swelling rate of the adhesive. CONCLUSIONS Our results suggest that the collective inter-play of the parameters pH, temperature and swelling ratio have an influence on the behavior of the denture adhesive. The results clearly highlight the need for developing a multi-parameter viscoelastic material model to understand the collective influence of physiological parameters on the performance of denture adhesives. Multi-parameter models can also potentially be utilized in numerically simulating denture adhesives using finite element simulations.

Age Ageing 2023; 52:afac276.

Abstract
Frailty is a complex and multidimensional condition wherein declines in physiologic reserve and function place individuals in a state of heightened vulnerability and decreased resiliency. There has been growing interest in both research and clinical settings to understand how to best define, assess and characterise frailty in older adults. To this end, various models and clinical assessment tools have been used to define and measure frailty. While differences exist among these models and tools, a common unifying theme is a focus on physical function and activity. Notably absent across many available conceptual models and clinical tools are items directly related to oral and swallowing function. This is an important oversight as widespread changes to both oral and swallowing function are evident in older adults. Indeed, emerging evidence suggests many of the functional domains affected in frail older adults, such as nutrition and sarcopenia, have cyclical relationships with impairments in oral (oral hypofunction) and swallowing function (dysphagia) as well. The increasing appreciation for the interrelationships among oral hypofunction, dysphagia and frailty provides an opportunity for refinement of frailty assessment and characterisation in older adults to incorporate metrics specific to oral and swallowing function.

FASEB J 2022; 36:e22631. [PMID: 36342387 DOI: 10.1096/fj.202200946r] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2022] [Revised: 09/23/2022] [Accepted: 10/17/2022] [Indexed: 11/09/2022]
Abstract
Macroautophagy/autophagy is critically involved in the process of salivary gland (SG) diseases such as xerostomia, which has a serious impact on quality of life. KRT14+ progenitor cells are found to be the main progenitors for maintaining the ductal homeostasis of the submandibular SGs. In this study, we investigated the role of ATG5 in SG KRT14+ cells in mice and humans. Human labial salivary glands (LSG) from primary Sjogren's syndrome (pSS) and non-pSS patients (normal), and submandibular glands (SMG) from Atg5flox/flox ; Krt14-Cre (cKO) mice were used. ATG5+ KRT14+ and p62+ KRT14+ cells were detected by immunofluorescence staining in LSG. TUNEL, immunofluorescence, immunohistochemistry, and western blot were performed to detect cell death in SMG. Saliva was collected in 12-week-old (12 W) and 32-week-old (32 W) mice, then the concentration of calcium and buffering capacity were detected to analyze the function of SG. We found that LSG from pSS patients showed increased p62 and decreased ATG5 in KRT14+ cells. We further revealed that in 32 W, (1) the function of salivary glands was significantly impaired in cKO mice, (2) cell death increased in cKO mice, but cl-Caspase 3 was not significantly changed, and (3) cleaved gasdermin D increased and was highly expressed in KRT14+ cells of cKO mice. After applying a pyroptosis inhibitor to 32 W mice, the reduced saliva flow rate was rescued. In addition, pyroptosis was also found in KRT14+ cells of pSS patients. Collectively, our results indicate that Atg5 deficiency would induce pyroptosis in mice SG, which could lead to functional impairments of SG.

Abstract
OBJECTIVES To prospectively assess the clinical performance and patient-reported outcomes of dental implants in dentate patients with primary and secondary Sjögren's syndrome (pSS and sSS, respectively) compared to patients without SS. MATERIALS AND METHODS Thirty-seven implants were placed in 17 patients with pSS/sSS and 26 implants in 17 non-SS patients to replace missing (pre)molars. Clinical performance, marginal bone-level changes, patient satisfaction, and oral health-related quality of life (OHRQoL) were assessed at 1 (T1), 6 (T6), 12 (T12), and 18 (T18) months after placement of the superstructure. Marginal bone-level changes were measured on standardized dental radiographs. Clinical parameters included implant and crown survival, plaque, bleeding and gingival indices, and probing depth. Patient satisfaction and OHRQoL were assessed with validated questionnaires. RESULTS Implant survival at T18 was 100% in the patients with pSS/sSS and 96.2% in the non-SS group. Mean marginal bone loss at T18 did not differ between patients with pSS/sSS and non-SS patients, 1.10 ± 1.04 and 1.04 ± 0.75 mm, respectively (p = .87). Clinical performance was good with no differences between the groups for all outcome measures (p > .05). OHRQoL in patients with pSS/sSS had improved significantly after placement of implant supported crowns at all measuring moments compared to baseline (p < .05). Nevertheless, patient satisfaction and OHRQoL remained significantly higher for patients without SS at all measuring moments (p < .05). CONCLUSION Dental implants can be successfully applied in dentate patients with pSS/sSS and have a positive effect on OHRQoL.

Curr Issues Mol Biol 2022; 44:2505-2528.

Abstract
Dry mouth is characterized by lower saliva production and changes in saliva composition. In patients with some salivary gland function remaining, pharmaceutical treatments are not recommended; therefore, new, more effective methods of promoting saliva production are needed. Hence, this study aimed to provide an overview of the histological changes in the salivary gland in the model of isoproterenol (ISO)-induced degenerative changes in male Wistar rats and to evaluate the protective effect of piceatannol. Thirty-two male Wistar rats were randomly divided into four groups: the control group, the ISO group, and the piceatannol (PIC)-1, and -2 groups. After the third day of the experiment, Iso (0.8 mg/100 g) was injected intraperitoneally (IP) twice daily into the animals. PIC was given IP in different daily doses (20 and 40 mg/kg) for three days before ISO and seven days with ISO injection. The salivary glands were rapidly dissected and processed for histological, histochemical, immunohistochemical (Ki-67), and morphometric analysis. Upon seven days of treatment with ISO, marked hypertrophy was observed, along with an increased number of positive Ki-67 cells. Proliferation was increased in some endothelial cells as well as in ducts themselves. Despite the significant decrease in proliferation activity, the control group did not return to the usual activity level after treatment with low-dose PIC. Treatment with a high dose of PIC reduced proliferative activity to the point where it was substantially identical to the results seen in the control group. An ISO-driven xerostomia model showed a novel protective effect of piceatannol. A new era of regenerative medicine is dawning around PIC’s promising role.

Abstract
Background Access is an important issue in health equality. Availability of dental services and cost subsidies is an important factor affecting access to denture restoration for the elderly. This study aims to explore access to denture restoration services in the elderly removable denture’s subsidy program of Taiwan. Methods Access to the elderly removable dentures subsidy program was measured from two aspects, that is, availability of subsidies and payment for these services and the characteristics of patients and their treatment needs. The first aspect included reimbursements and the number and location of subsidy clinics, and the second aspect included the age and gender distribution of patients and denture types. Information on reimbursement regulations and the number and location of dental clinics providing subsidized services were obtained from the website of the Taoyuan City Public Health Bureau, Taoyuan Hospital, Department of Statistics and Ministry of Health and Welfare. Data on patient characteristics and denture type were obtained through a retrospective survey. We selected individuals who participated in the elderly removable denture’s subsidy program from 2015 to 2018 at the Geriatric Dentistry Department of Taoyuan Hospital. We conducted data analysis using an interpretive approach. Results This study found that reimbursement amounts are inadequate, and the availability of subsidized services is low. Moreover, the proportion of male applications is slightly higher than that of females. In addition, among the applicants, removable partial dentures for single or two arches are the most common. Conclusions Problems of insufficient numbers of contracted hospitals and low reimbursement amounts are observed in the subsidy program, which are the key factors affecting access to denture restoration services among the elderly. Policymakers should exclude wealthy individuals and offer subsidy only to low-income elderly individuals with missing teeth who are in dire need of financial support to improve their dental health.

Each patient must wear the same pair of CDs or RPDs for more than 5 years. Oral health-related quality of life, dry mouth sensation, and level of anxiety were assessed by using the following questionnaires: Geriatric Oral Health Assessment Index (GOHAI), VAS (Visual Analog Scale) Xerostomia Questionnaire, and State-Trait Anxiety Inventory (STAI). These questionnaires were applied before oral rehabilitation (initially initial time point) and 3 months after insertion of new dentures (end time point). STATISTICAL ANALYSIS For the results of STAI-State, STAI-Trait, and GOHAI, the Wilcoxon test was applied to compare the time points. For the results of the VAS xerostomia questionnaire, two-way repeated measures ANOVA (analysis of variance) was applied, followed by the Tukey test. The p-values lower than 0.05 were considered statistically significant. RESULTS /CONCLUSION: For both groups, it was observed that 3 months after the insertion of new removable dentures: (1) there was an increase in oral health-related quality of life; (2) there was a reduction in anxiety (trait anxiety and state anxiety); and (3) there was a perception of greater salivation.

Abstract
Oral infections caused by Candida species are becoming more common, which may be related to an increase in the number of immunologically compromised patients as well as favorable conditions in the oral cavity that often include removable prosthetic appliances. The purpose of this study was to determine the presence of a particular Candida species in patients with PMMA and Cr-Co prosthetic appliances, as well as the salivary flow rate, and oral signs and symptoms. This investigation included a total of 120 subjects with different kinds of removable dentures. A sample of concentrated oral rinse was collected from all subjects in order to detect Candida colonization and identify the Candida species, a quantum of salivation was measured, and subjects were examined clinically. Candida spp. was predominant among the subjects who were denture wearers (p < 0.0001). In all subjects, the most frequently detected species was C.albicans. A statistically significant difference was found between the prevalence of C.albicans (p < 0.001) and C.krusei (p < 0.001) in denture wearers. Subjects with PMMA-based removable prosthetic appliances mostly demonstrated a significant decrease in salivation (p < 0.001), an increase in burning sensations (p < 0.001), and dry mouth (p < 0.001) compared to the subjects who wore partial dentures with Co–Cr metallic frameworks. Red oral lesions were more frequently found among the subjects with partial dentures with Co–Cr metallic frameworks (p < 0.001). Regardless of the material used for the denture, patients must be regularly checked by their dentists in order to prevent the development of oral lesions.

Abstract
INTRODUCTION There have been concerns that longstanding oral dryness secondary to Sjogren's syndrome may increase the risk of failure of dental implants. AIMS The aim of the present study was to determine the level of methodological quality of systematic reviews that evaluated the effectiveness of dental implants in patients diagnosed with Sjogren's syndrome. METHODS AND RESULTS Databases of PubMed/Medline, LILACS, Science Direct and Dare Cochrane to October 2020 were evaluated. A total of 833 articles were initially identified but following use of appropriate inclusion and exclusion criteria 4 papers were identified for detailed analysis. An eventual study sample comprised 722 implants placed in 189 patients with a 95.22% success rate, the minimum follow-up time was 45.2 ± 23.8 months and the maximum 125.5 months. The studies were assessed for their methodological quality by the AMSTAR 2 tool, in which 3 had critically low quality and one low quality. CONCLUSION Oral rehabilitation with dental implants in patients with Sjogren's syndrome seems to have a high success rate; however, the low quality of relevant reports highlights the need for primary and secondary studies with better methodological design in order to reduce bias and provide reassurance for this treatment option.

Abstract
OBJECTIVES To compare the psychometric properties of three OHRQoL indicators (GOHAI, OHIP-14, and OHIP-EDENT) in a group of complete edentulous subjects and to explore the ability of these instruments to distinguish between individuals with different prosthetic and oral health status. METHODS This was a cross-sectional study. Edentulous individuals aged 60 years and more were recruited between January 2019 and February 2020 in a medical and dental care centers. The Lebanese versions of GOHAI, OHIP-14, and OHIP-EDENT were used. External and internal consistencies were assessed using intraclass correlation coefficient (ICC) and Cronbach alpha, respectively. The concurrent validity was evaluated by testing the indicators against a proxy measure of a similar concept. To test their discriminative abilities, the ADD (GOHAI and OHIP) and SC (GOHAI and OHIP) scores were dichotomized according to the 25th and 75th percentile, respectively, and multivariate analyses were performed using sociodemographic, clinical, and subjective health parameters as explanatory variables. RESULTS Two hundred and two edentulous subjects (age: 72.94 ± 7.378 years) were included. The proportion of subjects with no impact was lower for OHIP-EDENT (7.9%) compared to GOHAI (28.2%) and OHIP-14 (38.6%). Reproducibility was satisfactory for all OHRQoL tools since they were able to reproduce the results consistently in time (ICC > 0.80). The Cronbach alpha values were greater than 0.8 indicating acceptable internal consistency. The concurrent validity of the three tools was acceptable since subjects with lower OHRQoL score were less satisfied with their dentures and reported a higher need for self-rated therapy. Concerning the discriminant validity, OHIP-EDENT was more discriminant than OHIP-14 and GOHAI, since it was more able to identify patients with poor prosthetic issues or using instable denture. CONCLUSION The OHIP-EDENT was more effective in identifying edentulous individuals with oral and prosthetic problems. Our results can help decide which dental instrument to use to assess the perception of oral health in edentulous individuals. More prospective studies are required to compare their evaluative properties.

Abstract
Background Although it is known that patients with primary Sjögren’s syndrome (pSS) have impaired dental conditions, incidence rates and incidence rate ratios of various dental diseases in these patients are not clear. The aim of this study was to investigate the frequency and prevalence of dental diseases in patients with pSS, and to evaluate the risk of common dental diseases in these patients. Methods A population-based retrospective cohort study was conducted using the data from the Taiwan's National Health Insurance Research Database. A total of 709 patients with newly diagnosed pSS between 2000 and 2012 were identified to form the pSS cohort. A comparison cohort of patients without pSS was assembled based on frequency matching for sex, 5-year age interval, and index year at a ratio of 10:1. All participants were followed until the end of the follow-up period or when the outcome of interest occurred. The incidence of dental caries, pulpitis, gingivitis, periodontitis, oral ulceration, and stomatitis were calculated using multiple Poisson regression models. Results A significantly higher prevalence (74.6% vs. 63.0%, P = 0.001) and frequency (median 5.37 vs. 1.45 per year, P < 0.001) dental visits were observed in patients with pSS compared with patients in the comparison cohort. The risk of dental caries (adjusted incidence rate ratio [aIRR] 1.64, P < 0.001), pulpitis (aIRR 1.42, P < 0.001), gingivitis (aIRR 1.43, P < 0.001), periodontitis (aIRR 1.44, P < 0.001), oral ulceration (aIRR 1.98, P < 0.001), and stomatitis (aIRR 2.06, P < 0.001) were significantly higher in patients with pSS. Conclusions In this nationwide, population-based cohort study, a higher prevalence and frequency of dental visits were found in patients with pSS. Patients with PSS had increased risk of six most common dental disorders, including dental caries, pulpitis, gingivitis, periodontitis, oral ulceration, and stomatitis. Rheumatologists should remain vigilant for the dental health of patients with pSS.

Abstract
BACKGROUND: Patient’s satisfaction and the preservation of abutments is the most important outcomes that the clinician seeks during fabrication of any dental treatment, especially when it is concerned with removable prosthodontic rehabilitation. AIM: The present study evaluates three different Removable Partial Denture (RPD) types restoring mandibular class II modification I edentulous cases with regards to patient’s satisfaction and abutments survival. METHODS: Forty-two partially edentulous patients were divided into three groups (Group I rehabilitated with Vitallium RPD, Group II rehabilitated with Vitallium RPD where the modification area restored with the surveyed bridge, Group III rehabilitated with Thermopress RPD). The patients were followed up for twenty-four months. Using a questionnaire, prosthodontic maintenance required was documented at the delivery and after 3 months. RESULTS: There was a significant difference regarding patient satisfaction for group III (P-value <0.05) while for groups I and II there was a non-significant difference (P-value >0.05). Regarding the survival rate, there was a non-significant difference between the three groups (P-value >0.05) at the end of twenty-four months of follow up. CONCLUSION: Patient satisfaction and abutment survival were better with Thermopress RPD than conventional Vitallium RPD or Vitallium RPD with a surveyed bridge restoring the modification area. Although a non-statistically significant difference was found in the survival rate of abutments between groups, a clinically important result was revealed as no abutments failures were reported in the Thermopress group.

Abstract
PURPOSE The impact of sialadenitis on osteoradionecrosis (ORN) is controversial. The aim of this study was to determine the association between sialadenitis and ORN. MATERIALS AND METHODS Participants were derived from the Taiwanese Longitudinal Health Insurance Database. From January 1, 2000 to December 31, 2008, cases of sialadenitis (International Classification of Diseases, Ninth Revision, Clinical Modification [ICD-9-CM] codes 527.2, 527.3, 527.5 to 527.7, 527.9, and 710.2) and ORN (ICD-9-CM codes 526.89, 526.5, 730.0, and 730.1) were identified. Different treatment modalities, including surgery versus medicine, were used to distinguish the severity of sialadenitis. The primary predictor variable was sialadenitis. The secondary predictor variable was severity of sialadenitis. The primary outcome variable was time to developing ORN. Other study variables were grouped for age, gender, risk factor, and medical treatment. Cox proportional hazard regression was used to investigate the associations between sialadenitis and ORN after adjusting for statistical confounders. RESULTS The sample was composed of 47,385 patients with a mean age of 46.6 years (standard deviation, 19.9 yr) and 37.2% were men. Twenty percent had a diagnosis of sialadenitis and 1.13% had a diagnosis of ORN. Sialadenitis was associated with an increased risk of ORN (hazard ratio [HR] = 1.93; 95% confidence interval [CI], 1.61-2.31; P < .0001). After adjustment for confounders, sialadenitis was associated with ORN (multivariable HR = 1.83; 95% CI, 1.52-2.19; P < .0001). Severity of sialadenitis was associated with an increased risk of ORN; risks for ORN were 1.79 (95% CI, 1.49-2.16; P < .0001) and 3.52 (95% CI, 1.67-7.44; P < .001) in patients with mild and serious sialadenitis, respectively, compared with the no-sialadenitis cohort. For the joint effect of ORN between sialadenitis and malignancy type, patients with sialadenitis had 11.6-fold risk for ORN (95% CI, 5.58-23.9) compared with patients without malignancy. CONCLUSIONS Sialadenitis markedly increased the risk to develop ORN. The severity of sialadenitis was positively correlated with the incidence of ORN.

Abstract
OBJECTIVES Systematic review with meta-analysis of interventions for dry mouth symptoms and hyposalivation of Sjögren's syndrome (SS). MATERIALS AND METHODS We searched MEDLINE, Cochrane Central and EMBASE up to February 2018 for randomized trials of interventions for dry mouth and hyposalivation of SS. The primary outcome was the mean change in xerostomia symptoms. The secondary outcomes included changes in salivary flow and quality of life. We used the Cochrane risk of bias tool for individual studies and the GRADE method to summarize the quality of evidence across studies for the included outcomes. RESULTS Thirty-six studies (3,274 patients) were included in the systematic review. Results from the meta-analyses showed high-quality evidence that pilocarpine was superior to placebo in reducing dry mouth symptoms. We found moderate quality of evidence that pilocarpine, rituximab and interferon-alpha were more effective than placebo in increasing salivary flow, with the relevant effect size being large for pilocarpine, and notably smaller for rituximab and interferon-alpha. CONCLUSION Clinicians should be very confident in the beneficial effects of pilocarpine upon dry mouth symptoms of SS and moderately confident that pilocarpine, rituximab and interferon-alpha can have beneficial effects upon salivary flow. Adverse events are common. The use of other treatment modalities cannot be supported on the basis of current evidence.

Abstract
The retention and comfort of wearing prosthesis mainly depends on saliva. In reduced saliva conditions, such as xerostomia or radiation therapy, the oral mucosa tends to become dry and ulcerated, leading to the patient's inability to retain the prosthesis. Various techniques have been reported in the literature regarding the use of a reservoir with holes in dentures. The results have not been satisfactory because the flow of the salivary substitute could not be controlled and with frequent cleaning of the denture being necassary to maintain the patency of the reservoir holes. A newer technique for incorporation of a palatal reservoir with controlled artificial salivary flow in complete denture is being explained in this article, which improved the denture retention, comfort, mastication and speech of the patient.

Abstract
Sjögren's syndrome (SS), an autoimmune disorder, affects the exocrine glands, including the lacrimal and salivary glands. It is characterized by symptoms of dry eye and dry mouth. As secretion of saliva decreases, patients with SS experience rampant caries, pain in the oral mucosa, inflammation and hardening of the salivary glands, abnormal taste, dysphagia, and loss of teeth earlier than healthy individuals. A removable partial denture is often used as a prosthesis after tooth loss. Compromised salivary lubrication, however, can produce traumatic ulceration of the mucosa, making use of a removable prosthesis in SS patients painful. In such cases, a dental implant is likely to be requested as an alternative. This report describes dental implant treatment in an SS patient, a 50-year-old woman who presented with the chief complaint of masticatory dysfunction and pain due to a removable partial denture. Eight implants were placed in the maxillary and mandibular first molar tooth and second molar tooth regions. Following a 4-month non-loading period, second-stage surgery and provisional restoration with a screwretained implant temporary crown were performed. Screw-retained superstructures were fitted by means of a customized titanium abutment and zirconia crown as the final restoration. No complications, including inflammation of peri-implant soft tissue or resorption of peri-implant bone, were observed at 3 years following placement of the superstructures.

Abstract
The structure and function of exocrine glands are negatively affected by human immunodeficiency virus (HIV) infection and its co-morbidities, including innate and adaptive immune responses. At the same time, exocrine function may also be influenced by pharmacotherapies directed at the infectious agents. Here, we briefly review the role of the salivary glands and lacrimal glands in normal physiology and exocrine pathogenesis within the context of HIV infection and acquired immune deficiency syndrome (AIDS), including the contribution of antiretroviral therapies on both. Subsequently, we discuss the impact of HIV infection and the types of antiretroviral therapy on disease management and therapy development efforts.

Abstract
OBJECTIVE The study evaluated the association of the sociodemographic, behavioural variables and the oral conditions with the presence of oropharyngeal dysphagia in long-term care older persons. BACKGROUND Due to the influence of ageing, swallowing may be altered both in people with natural teeth and in those who have dentures or tooth loss. MATERIALS AND METHODS This cross-sectional study evaluated 115 individuals older than 60 years, living in long-term care institutions of the State of Rio Grande do Sul in 2016. The diagnosis of dysphagia happen using a clinical speech evaluation, based on the research of signals and symptoms of alterations during deglutition, and on an oral sensory-motor evaluation. The dental clinical evaluation examined the oral cavity, teeth and dental prostheses, including a Xerostomia assessment. Poisson Regressions with robust variance was calculated were used to estimate crude and adjusted Prevalence Ratios(PR) and their IC95%. RESULTS The sample was mostly comprised of older women (67.0%), with more than 81 years of age (44.3%) and edentulous (54.3%). Diagnosis of oropharyngeal dysphagia was verified in 60.9% of the participants. In the final model, older persons who presented no pair (PR=1.52(CI95%=1.02-2.40)) had a highest prevalence of oropharyngeal dysphagia, when compared to older persons who presented 8 to 14 mixed pairs, as well as those older persons who had more complaints related to symptoms of Xerostomia (PR=2.86(CI95% 1.58-5.18)). CONCLUSION Institutionalised older persons with a poor oral health condition are associated with a higher prevalence of oropharyngeal dysphagia, as well as with the presence of Xerostomia.

Abstract
Physiological whole saliva is a unique body fluid constantly washing the mucous membranes of the mouth, throat, and larynx. Saliva is a clear, slightly acidic mucinous-serous secretion, composed of various electrolytes, small organic substances, proteins, peptides, and polynucleotides. There are many ways to use saliva as a biological fluid (biofluid). The significant advantages of saliva as a unique diagnostic material are its availability and the noninvasive method of collection. The aim of this review is to emphasize the diagnostic value of saliva as a research material in the configuration of its structure and secretion disorders. The data were obtained using the MEDLINE (PubMed) search engine, as well as an additional manual search. The analysis covered 77 articles selected from a group of 1986 publications and initially qualified for devising. The results were evaluated and checked for the correctness of qualifying in accordance with inclusion and exclusion criteria. The diagnostic use of saliva has attracted the attention of many researchers due to its noninvasive nature and relative simplicity of collection. In addition, it should be noted that the determination of chemical and physical saliva parameters can be effectively performed in the patient's presence in the dental office.

Abstract
INTRODUCTION Edentulism is one of the debilitating states affecting a significant portion of the geriatric population. It is often considered as the ultimate marker for predicting the pressure and burden on oral health. Respiration is also a routine vital function running continuously through the human body and most commonly assessed by a spirometer. Hence, we planned the present study to assess the impact of complete dentures on the functioning of the respiratory system. MATERIALS AND METHODS In the present study, a spirometric assessment of the effect of complete dentures on respiratory performance was done. A total of 100 subjects were included, and diagnostic spirometer was used for carrying out the spiro-metric test at different stages of each subject. The spirometric test was carried out at four different stages: In the absence of both the denture (AODs), with both the dentures (maxillary and mandibular) inserted in the patient's mouth (BDs), with only maxillary denture inserted in the oral cavity (UDs), and finally, by inserting only the mandibular dentures in the oral cavity (LDs). Forced vital capacity (FVC), peak expiratory flow (PEF), forced expiratory volume in 1 second (FEV1), and forced expiratory flow between 25 and 75% (FEF25-75) were evaluated. All the results were compiled and assessed using Statistical Package for the Social Sciences (SPSS) software. RESULTS Of the total 100 subjects included in the study, 42 were males and 58 were females. The mean FVC values of AOD, BD, LD, and UD group were 3.10, 3.02, 2.90, and 2.93 respectively. The mean PEF values of AOD, BD, LD, and UD group were 5.79, 5.60, 5.40, and 5.48 respectively; 2.39, 2.35, 2.33, and 2.32 were the mean FEV1 values observed in AOD, BD, LD, and UD group respectively. Statistically significant results were obtained while comparing AOD-FVC and BD-FVC and other oral conditions. CONCLUSION Spirometric values of respiratory functional tests in edentulous patients might be unfavorably affected by wearing complete dentures. CLINICAL SIGNIFICANCE Since subjects without complete dentures exhibited a maximum value of respiratory functional test, respiratory exercise protocols should also be carried in denture-wearing edentulous patients for increasing the performance of the respiratory system.

Abstract
Context: Probiotics have been prescribed to old aged patients’ invariably with or without complete dentures for improving their digestive process. It is mentioned that probiotics do have an effect in increasing the amount of saliva in the oral cavity. Therefore, this study was planned to evaluate the amount and pH of saliva after using probiotics for 60 days in completely edentulous patients. Aim: This study aims to evaluate the amount and pH of saliva of edentulous patients before and after using probiotics. Settings and Design: The interventional prospective study was conducted at the department of prosthodontics of the institute. Methods: The study was conducted on edentulous patients. The whole unstimulated and stimulated saliva was collected at baseline and amount, and pH was measured. Then, each patient was given probiotic capsules reaching 3.3 × 107 CFU/g to consume daily once for 60 days. Saliva was recollected from patients, and its amount and pH was calculated and compared with baseline. Statistical Analysis Used: STATAIC-13. Results: On comparison of saliva before and after consuming probiotics, there was an increase in the mean unstimulated and stimulated saliva from baseline to that after 60 days, the difference being 0.406 and 0.433, respectively. The difference was statistically significant with P < 0.001. The mean pH at baseline was 7.818 ± 0.231 which increased after 60 days to 7.825 ± 0.189, the difference being 0.007. Conclusion: This study concluded that probiotics increase the amount of saliva of completely edentulous patients and so it can be helpful in patients suffering from xerostomia/hyposalivation.

Abstract
OBJECTIVE Denture adhesives are widely used to avoid the detachment and sliding of dentures. However, the adhesion properties can be affected by variation in mouth conditions such as the level of salivation. The objective of this study was to understand the effect of environmental conditions on the adhesion properties of a commercially available denture adhesive named as Poligrip® Free manufactured by GlaxoSmithKline Ltd., UK and to identify the reasons for the observed variation in its adhesion strength. METHODS The failure mechanisms of denture adhesive have been assessed through using different physical, mechanical and thermal characterization experiments. All methods were used in different pH, temperatures, and salivation conditions and at the end, a strategy was proposed to overcome the failure of the paste in hyposalivation as well. RESULTS In vitro models mimicking the denture gingival interface were designed to evaluate the adhesion properties of the investigated adhesive. Changes in the adhesion strength in response to three major factors related to the oral conditions including level of salivation, pH, and temperature were measured. The results of lap shear, tensile test, and internal interactions suggested a cohesion failure, where the lowest adhesion strength was due to hyposalivation. Fourier transform infrared spectroscopy (FTIR) and rheological analysis confirmed the importance of hydrogen bonds and hydration in the adhesion strength of the paste. SIGNIFICANCE The investigated scenarios are widely observed in patient using denture adhesives and the clinical reports have indicated the inconsistency in adhesion strength of the commercial products. After identifying the potential reasons for such behavior, methods such as the addition of tripropylene glycol methyl ether (TPME) to enhance internal hydrogen bonds between the polymers are proposed to improve adhesion in the hyposalivation scenario.

Abstract
A comprehensive evaluation of oral and ocular symptoms and findings in primary Sjögren’s syndrome (pSS) patients may provide valuable information for management. Medical history was obtained from female pSS patients, and sex- and age-matched non-SS patients with sicca symptoms (non-SS sicca controls) as well as healthy subjects without sicca complaints (healthy controls). Oral (Summated Xerostomia Inventory, SXI) and ocular (McMonnies Dry Eye questionnaire, MDEIS, and Ocular Surface Disease Index, OSDI) subjective complaints were recorded. Objective findings including clinical oral dryness scores (CODS), unstimulated and stimulated saliva secretion rates (UWS/SWS), Schirmer I test, tear osmolarity, tear film break-up time (TFBUT), and ocular surface staining (OSS) were determined. The pSS and non-SS sicca controls were extensively troubled by subjective dryness, while the pSS group had higher CODS, significantly lower saliva and tear secretion, shorter TFBUT and higher OSS than both control groups. Furthermore, candida counts were significantly higher in the pSS patients. In the pSS group, subjective oral dryness significantly correlated with ocular dryness (MDEIS: r = 0.5, OSDI: r = 0.413) and SWS was significantly correlated with Schirmer I (r = 0.419). The findings imply that interdisciplinary subjective and objective evaluation of patients with xerostomia and xerophthalmia not only have implications for patient care, but also may guide clinicians in differentiating between pSS and non-SS sicca patients.

Abstract
Basic science courses are extremely important as a foundation for scaffolding knowledge and then applying it in future courses, clinical situations as well as in a professional career. Anatomical sciences, which include tooth morphology, oral histology, oral embryology, and head and neck anatomy form a core part of the preclinical courses in dental technology programs. In this article, the importance and relevance of anatomical sciences to dental personnel with no direct contact with patients (dental technicians) and limited discipline related contact with patients (dental prosthetists) is highlighted. Some light is shed on the role of anatomical sciences in the pedagogical framework and its significance in the educational process and interprofessional learning of dental technicians and prosthetists using oral biology as an example in the dental curriculum. To conclude, anatomical sciences allow dental technicians and prosthetists to a gain a better insight of how tissues function, leading to a better understanding of diagnosis, comprehensive treatment planning and referrals if needed. Patient communication and satisfaction also increases as a result of this deep understanding of oral tissues. Anatomical sciences bridge the gap between basic science, preclinical, and clinical courses, which leads to a holistic approach in patient management. Finally, treatment outcomes are positively affected due to the appreciation of the macro and micro structure of oral tissues. Anat Sci Educ 10: 395-404. © 2016 American Association of Anatomists.

Abstract
OBJECTIVE Oral fungal infection is generally associated with dysbiosis related to antibiotic use, immunodeficiency, or frailty. However, fungal colonization in a typical population without apparent symptoms and its associated conditions are poorly understood. In this study, oral fungal colonization in community-dwelling and independently living elderly populations was evaluated and factors affecting fungal colonization were analyzed. SUBJECTS AND METHODS The subjects (410; 181 males and 229 females) were 75-99 years of age; those under prior antibiotic use were excluded. Fungal populations in the saliva were evaluated by PCR-based molecular techniques. Body mass index (BMI), smoking habits, and oral health conditions were examined. RESULTS Salivary fungal amounts exceeded 104 CFU/ml in 63 (15.4%) of 410 subjects. Candida albicans was most frequently detected (98.4%), followed by Candida glabrata (54.0%), and Candida dubliniensis (38.1%) in those subjects with fungi at 104 CFU/ml or over. Fungi at 104 CFU/ml or over in the presence of C. glabrata or C. dubliniensis was significantly associated with low BMI. CONCLUSIONS Candida albicans, C. glabrata, and C. dubliniensis dominated the oral mycobiome in Japanese community-dwelling elderly. Lower BMI might signify compromised health status and thus could result in susceptibility to specific candidiasis by C. glabrata and C. dubliniensis.

Abstract
OBJECTIVE This study aims to analyze the salivary peptidome/proteome of edentulous subject with respect to dentate control subjects. DESIGN Unstimulated whole saliva, collected from 11 edentulous subjects (age 60-76 years) and 11 dentate age-matched control subjects, was immediately treated with 0.2% aqueous trifluoroacetic acid and the acidic soluble fraction analyzed by High Performace Liquid Chromatography-Mass Spectrometry. The relative abundance of the salivary peptides/proteins was determined by measuring the area of the High Performace Liquid Chromatography-Mass Spectrometry eXtracted Ion Current peaks which is linearly proportional to peptide/protein concentration under identical experimental conditions. Levels of salivary peptides/proteins in the two groups were compared by the nonparametric Mann-Whitney test to evidence statistically significant differences. RESULTS Levels of cystatin A, S-glutathionylated, S-cystenylated, S-S dimer derivatives of cystatin B and S-glutathionylated derivative of SPRR3, were found significantly higher in edentulous subjects with respect to dentate controls. The major peptides and proteins typically deriving from salivary glands did not show any statistically significant differences. CONCLUSIONS Cystatin A, S-glutathionylated, S-cystenylated, S-S dimer derivatives of cystatin B and S-glutathionylated derivative of SPRR3, which are mainly of intracellular origin and represent the major constituents of the cornified cell envelope are a clue of inflammation of mucosal epithelia.

Abstract
Aim and Objectives: In the denture wearing people, saliva is necessary to create adhesion, cohesion, and surface tension that ultimately leads to the increased retention of the denture. Medications have some influence on the flow rate of saliva and denture retention. The present study evaluates the effect of complete denture wear on the flow rate of saliva in both medicated and apparently healthy patients. Materials and Methods: The participants were 42 edentulous individuals aged 35–70 years requiring complete denture prostheses. The participants were divided into two groups of medicated and unmedicated. Unstimulated whole saliva was collected at 24 h and 3 months after the insertion of new complete dentures in both the groups. The data obtained were analyzed using Student's paired t-test and unpaired t-test. Intergroup changes were compared with unpaired t-test. Intragroup changes were compared with paired t-test using the Statistical Package for Social Sciences, version 22.0. Results: In the unmedicated group, the mean salivary flow rate was high at 24 h after denture insertion when compared to before denture insertion (P = 0.001 VHS). In the medicated group, the observation was highly significant (P = 0.007 HS) 24 h after denture insertion and after 3 months (P = 0.02 S) when compared to before denture insertion. Conclusion: No significant difference in the salivary flow rate was found 3 months after denture insertion when compared to before denture insertion for both the medicated and unmedicated groups.

Abstract
The prevalence of prosthodontic treatment has been well recognized, and the need is continuously increasing with the ageing population. While the oral mucosa plays a critical role in the treatment outcome, the associated biomechanics is not yet fully understood. Using the literature available, this paper provides a critical review on four aspects of mucosal biomechanics, including static, dynamic, volumetric and interactive responses, which are interpreted by its elasticity, viscosity/permeability, apparent Poisson's ratio and friction coefficient, respectively. Both empirical studies and numerical models are analysed and compared to gain anatomical and physiological insights. Furthermore, the clinical applications of such biomechanical knowledge on the mucosa are explored to address some critical concerns, including stimuli for tissue remodelling (interstitial hydrostatic pressure), pressure–pain thresholds, tissue displaceability and residual bone resorption. Through this review, the state of the art in mucosal biomechanics and their clinical implications are discussed for future research interests, including clinical applications, computational modelling, design optimization and prosthetic fabrication.

Nitric Oxide Concentration and Other Salivary Changes after Insertion of New Complete Dentures in Edentulous Subjects. Int J Dent 2016; 2016:8351427. [PMID: 27034674 PMCID: PMC4789480 DOI: 10.1155/2016/8351427] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2015] [Accepted: 02/07/2016] [Indexed: 11/25/2022] Open
Abstract
Objective. To assess changes in levels of salivary nitric oxide (NO) after insertion of new complete dentures and its association with clinical and salivary parameters. Methods. Nineteen fully edentulous subjects were included, mean age 64.4. Unstimulated whole saliva was collected before and after insertion of the dentures, at follow-up visits, and after 12 months. The concentration of the final stable NO product (nitrite) was measured by a colorimetric assay based on the Griess reaction. Clinical parameters were assessed during all clinical visits. Results. Functional adaptation to the dentures progressively improved, with no complaints at the long-term follow-up. NO concentration was not influenced by the level of functional adaptation, presence of injuries to the mucosa, salivary flow, and saliva viscosity. Pairwise comparison showed a reduction in NO concentration at the first follow-up compared to baseline values but differences were not statistically significant. Significant differences were observed in NO concentrations at the long-term follow-up when compared to the first (p = 0.024) and second (p = 0.027) visits. Conclusion. NO concentration reduced after denture insertion and returned to baseline levels in the long-term follow-up. This appears to be an autonomic response of the body and provides valuable complementary information for the management of the edentulous patient.

Abstract
AIM Studies from Pakistan on salivary dysfunction are lacking, and the Pakistani elderly population is rapidly growing. Among the most common problems in the elderly that could have a deleterious impact on their quality of life are salivary gland hypofunction (SGH), diabetes mellitus (DM), and the intake of drugs with adverse effects on salivary function. In the present study, we aimed to find the association of SGH with DM and drugs among the elderly in Karachi, Pakistan. METHODS The inclusion criterion was affirmative answers to a series of standardized questions related to the symptoms of dry mouth. A total of 110 individuals were selected from a convenience sample of 200 people aged between 60 and 70 years. Diabetes, drug use, and SGH in the participants were determined by detailed medical and drug history, clinical examination, and sialometry. RESULTS Similar to their international counterparts, the majority of the study participants demonstrated objective evidence of SGH. More importantly SGH was found to be statistically significant with respect to DM and medication (P < 0.05). For participants on medication, the minimum and maximum salivary flow rates were found to be 0.09 mL/min and 0.3 ml/min, respectively, whereas the minimum and maximum salivary flow rates in diabetic participants were 0.01 mL/min and 0.09 mL/min, respectively. CONCLUSION In the present study, the majority of elderly participants whose presenting complaint was oral dryness was found to have objective evidence of SGH, with a statistically-significant association with DM and drugs.

Chemokine expression of oral fibroblasts and epithelial cells in response to artificial saliva. Clin Oral Investig 2015; 20:1035-42.

Abstract
OBJECTIVES Artificial saliva is widely used to overcome reduced natural salivary flow. Natural saliva provokes the expression of chemokines in oral fibroblasts in vitro. However, if artificial saliva changes the expression of chemokines remains unknown. MATERIALS AND METHODS Here, we investigated the ability of Saliva Orthana®, Aldiamed®, Glandosane®, and Saliva Natura® to change the expression of chemokines in human oral fibroblasts and the human oral epithelial cell line HSC-2 by means of reverse transcription polymerase chain reaction and immunoassays. Mucins isolated from bovine submaxillary glands and recombinant human mucin 1 were included in the bioassay. Formazan formation and LIVE/DEAD® staining determined the impact of artificial saliva on cell viability. The involvement of signaling pathways was determined by pharmacologic inhibitors and Western blotting. RESULTS In gingival fibroblasts, Saliva Orthana®-containing mucins provoked a significantly increased expression of CXC ligand 8 (CXCL8, or interleukin 8), CXCL1, and CXCL2. Immunoassays for CXCL8 and CXCL1 confirmed the translation at the protein level. The respective dilution of artificial saliva had no impact on formazan formation and LIVE/DEAD® staining. Mucins isolated from bovine submaxillary glands also increased the panel of chemokine expression in gingival fibroblasts. BAY 11-7082, a nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) inhibitor, but also TAK-242, an inhibitor of toll-like receptor 4 signaling, blocked chemokine expression of Saliva Orthana® and bovine mucins. In HSC-2 cells, Glandosane® significantly increased CXCL8 expression. CONCLUSIONS Saliva Orthana® stimulated chemokine expression in gingival fibroblasts. Mammalian mucins, but also possible contaminations with endotoxins, might contribute to the respective changes in gene expression. Epithelial cells have a differential response to artificial saliva with Glandosane® changing CXCL8 expression. CLINICAL RELEVANCE Artificial saliva can incite a cellular response, if however the changing expression of chemokines by isolated fibroblasts and epithelial cells in vitro translates into a clinical condition, is not clear.

Abstract
The purpose of study was to analyze the participants' opinions concerning the effectiveness of 6 denture adhesives (DA). The study group included 60 participants. Criteria for selecting the patients were as follows: reduced retention and stabilization of maxillary complete dentures and xerostomia. These features were evaluated on basis of clinical examination and standard sialometry tests (u-SFR). Retention of maxillary dentures was scored by modified Kapur index before application of DA. All participants were divided randomly into 6 groups regarding the use of the 6 DA during a 6-month period. After this time, participants completed an HRQL questionnaire. DA noticeably improved retention and stabilization of maxillary complete dentures. DA in the glue form had the best retention effectiveness in participants with xerostomia. These materials are difficult to clean from the denture base. The data are presented in tables and figures. The results of the study collected positive influence of adhesives on retention of dentures in xerostomia patients. The cleaning dentures and denture bearing tissues was difficult. DA help in the use of prostheses, but it is also necessary for the treatment of the causes and symptoms of xerostomia.

Abstract
The aim of this study is to investigate the influence of hormone therapy on salivary flow in menopausal women. It is a case-control study involving 86 post-menopausal women. The case group consisted of 47 women undergoing estroprogestative or estrogen hormone replacement therapy (HRT), and the control group consisted of 39 women who did not receive any HRT. All patients were submitted to a standard questionnaire, followed by total stimulated sialometry and determination of body mass index (BMI). The salivary flow was classified as follows: normal (1.0-3.0 mL/min), low (0.7-1.0 mL/min), and hyposalivation (<0.7 mL/min). The results were analyzed statistically by the chi-square test, logistic regression model, and linear regression (p < 0.05). The HRT group presented an association of protection, even after adjusting the analysis, for low salivary flow (Adjusted OR = 0.22; 95% CI = 0.05-0.88; p = 0.034), and hyposalivation (Adjusted OR = 0.30; 95% CI = 0.10-0.92; p = 0.036). The results suggest that estroprogestative therapy (β = + 0.53; p = 0.022) has greater influence on the increase of salivary flow than estrogen therapy (β = +0.35; p = 0.137). The study concludes stating salivary flow was influenced by HRT on the post-menopausal women studied.

Abstract
Different reasons can contribute to classifying dental prosthesis wearers as high-risk individuals in relation to dental biofilm accumulation. These include a past history of oral disease, age and additional retentive areas. Other common complaints include inflammation and halitosis. Moreover, prosthesis replacement and prosthetic pillar loss are generally associated with caries and periodontal disease recurrence. Therefore, the present study undertook to make a critical review of the literature, aiming at discussing the main aspects related to chemical agent prescriptions for dental prosthesis wearers. Most of the articles were selected based on relevance, methods and availability in regard to the specific subject under investigation, without considering publication year limitations. Different types of prostheses and their impact on teeth and other oral tissues were reported. It was demonstrated that there is greater biofilm buildup and increased inflammatory levels in the presence of different types of prostheses, suggesting that additional measures are required both on population-wide and individual levels in order to control these factors. Mechanical control consists of a combination of manual or electric toothbrush and toothpaste, as well as specific devices for interdental cleaning. Although many chemical agents exhibit antimicrobial benefits when used for prosthesis disinfection, only a few agents can be used safely without causing damage. Regarding the selection of antiseptics by the overall population, chlorhexidine is the most indicated in the short term and in sporadic cases. The most indicated adjuncts to overcome the deficiencies and limitations of daily mechanical biofilm control are products containing essential oils as active ingredients.

Abstract
Xerostomia is a common complaint of nearly half of the elderly population and about one-fifth of younger adults. It causes several signs and symptoms, and compromise oral functions and health-related quality-of-life. Multiple reasons are proposed to describe the etiology of xerostomia such as local factors, psychogenic factors, and systemic diseases. In order to manage xerostomia effectively, identification of the main causality is mandatory. The aim of this review was to present systemic diseases leading to xerostomia with their mechanisms of action. We used various general search engines and specialized databases such as Google, Google Scholar, Yahoo, PubMed, PubMed Central, MedLine Plus, Medknow, EBSCO, ScienceDirect, Scopus, WebMD, EMBASE, and authorized textbooks to find relevant topics by means of Medical Subject Headings keywords such as "xerostomia," "hyposalivations," "mouth dryness," "disease," and "systemic." We appraised 97 English-language articles published over the last 40 years in both medical and dental journals including reviews, meta-analysis, original papers, and case reports. Upon compilation of relevant data, it was concluded that autoimmune diseases most frequently involve salivary glands and cause xerostomia followed by diabetes mellitus, renal failure, and graft-versus-host disease. Moreover, the underlying mechanisms of systemic disease-related xerostomia are: autoimmunity, infiltration of immunocompetent cells, granuloma formation, fibrosis and dehydration, deposition of proteinaceous substances, bacterial infection, and side-effects of medications.

Abstract
OBJECTIVES The aims of this pilot study were to investigate the prevalence of xerostomia and hyposalivation and their impact on quality of life in a cohort of elderly patients including dental status and the character of potential prosthetic restorations as independent variables. METHODS Patients aged 60 years or older without any objective or subjective need for prosthodontic treatment taking part in a regular recall programme were included in the trial. Quality of life was assessed using the German version of the GOHAI; prevalence and severity of xerostomia was investigated using the shortened version of the Xerostomia Inventory (XI). Stimulated salivary flow rate was determined using a sialometric approach. Dental status and the character of prosthetic restorations (no/fixed restorations and removable but tooth-supported dentures vs. gum-supported dentures) were assessed in a clinical examination by experienced dentists specialized in prosthodontic treatment. RESULTS A total of 68 patients were included in the trial; a prevalence of xerostomia of 16% and a prevalence of hyposalivation of 31% were identified. The quality of life in the study cohort decreased significantly as a function of xerostomia severity but not salivary flow; moreover, a significant impact of the number of teeth/implants in the upper jaw and the presence of gum-supported dentures in both jaws on GOHAI scores could be identified. CONCLUSIONS Within the limitations of a pilot study, the results support the assumption that the quality of life in elderly patients is particularly related to their subjective perception of xerostomia. A decline in salivary flow, the dental status and the character of prosthetic restorations appear to play a subordinate role for the quality of life in elderly patients. CLINICAL SIGNIFICANCE The quality of life in elderly patients may be severely diminished due to an increased subjective perception of dry mouth. Dental treatment should focus on alleviating xerostomia, whereas the impact of dental status and prosthetic restoration appear to be subordinate.

Abstract
Head and neck (H&N) radiation therapy (RT) can induce irreversible damage to the salivary glands thereby causing long-term xerostomia or dry mouth in 68%-85% of the patients. Not only does xerostomia significantly impair patients' quality-of-life (QOL) but it also has important medical sequelae, incurring high medical and dental costs. In this article, we review various measures to assess xerostomia and evaluate current and emerging solutions to address this condition in H&N cancer patients. These solutions typically seek to accomplish 1 of the 4 objectives: (1) to protect the salivary glands during RT, (2) to stimulate the remaining gland function, (3) to treat the symptoms of xerostomia, or (4) to regenerate the salivary glands. For each treatment, we assess its mechanisms of action, efficacy, safety, clinical utilization, and cost. We conclude that intensity-modulated radiation therapy is both the most widely used prevention approach and the most cost-effective existing solution and we highlight novel and promising techniques on the cost-effectiveness landscape.

Abstract
There are no clearly established protocols for the treatment of dry mouth. The aim of this paper is a systematic review of the literature of the past 10 years using the words « dry mouth », « prognosis », « treatment » and « dentistry ». The initial search found 1,450 entries and within the restriction « clinical trials OR randomized controlled trial OR systemic reviews » it has been reduced to 522, which 145 were meta-analysis and systematic reviews. Papers not relevant to the issue were removed reducing the entries to 53. Twenty-four were dismissed (8 irrelevant, 7 reviews without adequate information and 9 personal opinions). Of the 29 items tested, 15 were controlled trials, 2 uncontrolled trials, 4 observational studies, 2 systematic reviews and 5 non systematic reviews. The most studied patients were Sjögren's syndrome and the irradiated patients. Treatments are focused on the etiology, prevention, symptomatic, local salivary stimulation and systemic treatments. It can be concluded that treatment must be individualized, salivary substitutes and mechanical stimulation techniques can be applied.

Abstract
Ideally, healthcare systematic reviews (SRs) should be beneficial to practicing professionals in making evidence-based clinical decisions. However, the conclusions drawn from SRs are directly related to the quality of the SR and of the included studies. The aim was to investigate the methodological quality and key descriptive characteristics of SRs published in prosthodontics. Methodological quality was analysed using the Assessment of Multiple Reviews (AMSTAR) tool. Several electronic resources (MEDLINE, EMBASE, Web of Science and American Dental Association's Evidence-based Dentistry website) were searched. In total 106 SRs were located. Key descriptive characteristics and methodological quality features were gathered and assessed, and descriptive and inferential statistical testing performed. Most SRs in this sample originated from the European continent followed by North America. Two to five authors conducted most SRs; the majority was affiliated with academic institutions and had prior experience publishing SRs. The majority of SRs were published in specialty dentistry journals, with implant or implant-related topics, the primary topics of interest for most. According to AMSTAR, most quality aspects were adequately fulfilled by less than half of the reviews. Publication bias and grey literature searches were the most poorly adhered components. Overall, the methodological quality of the prosthodontic-related systematic was deemed limited. Future recommendations would include authors to have prior training in conducting SRs and for journals to include a universal checklist that should be adhered to address all key characteristics of an unbiased SR process.

Abstract
The study investigated the impact of xerostomia on oral health and quality of life (QoL) among patients infected with human immunodeficiency virus (HIV) who were attending for routine HIV monitoring in Australia. This cross-sectional, self-administered questionnaire survey and oral screening (OS) included 100 subjects who were HIV positive. The OS was conducted by a dentist blinded to the subject's survey responses. Xerostomia was determined by asking the subjects a single question. Subjects with xerostomia were found to have increased caries activity and poorer QoL, especially in the psychological dimensions of the oral health impact profile. Age and duration of HIV infection were associated with xerostomia. Early diagnosis of xerostomia and intervention with preventive dental care would potentially reduce caries and improve QoL among patients infected with HIV-1. Ongoing chronic inflammation of salivary glands despite the beneficial effects of antiretroviral therapy may play a role in the etiology of xerostomia in patients infected with HIV and requires further study.

J Appl Oral Sci 2012; 20:157-61.

Abstract
OBJECTIVE The aim of this study was to evaluate the effectiveness of clinical criteria for the diagnosis of hyposalivation in hospitalized patients. MATERIAL AND METHODS A clinical study was carried out on 145 subjects (48 males; 97 females; aged 20 to 90 years). Each subject was clinically examined, in the morning and in the afternoon, along 1 day. A focused anamnesis allowed identifying symptoms of hyposalivation, like xerostomia complaints (considered as a reference symptom), chewing difficulty, dysphagia and increased frequency of liquid intake. Afterwards, dryness of the mucosa of the cheeks and floor of the mouth, as well as salivary secretion during parotid gland stimulation were assessed during oral examination. RESULTS Results obtained with Chi-square tests showed that 71 patients (48.9%) presented xerostomia complaints, with a significant correlation with all hyposalivation symptoms (p <0.05). Furthermore, xerostomia was also significantly correlated with all data obtained during oral examination in both periods of evaluation (p<0.05). CONCLUSION Clinical diagnosis of hyposalivation in hospitalized patients is feasible and can provide an immediate and appropriate therapy avoiding further problems and improving their quality of life.

Abstract
OBJECTIVES To investigate the prevalence of dry mouth in a select sample of edentulous Jordanian older population wearing complete dentures and to evaluate its impact on oral functions. BACKGROUND The prevalence and impact of Xerostomia as a cofactor in causing denture problems in Jordanians have not been previously investigated. MATERIALS AND METHODS This study included 455 participants (253 men and 202 women). Perception of dry mouth was measured by a pilot-tested questionnaire. Xerostomic status was confirmed clinically. Complete denture function was also assessed. RESULTS One hundred and thirty six subjects (29.9%) had reported a subjective feeling of dry mouth with a prevalence of 24.9% in men (n = 63) and 36.1% in women (n = 73) (p < 0.01). 136 of the 145 subjects with satisfactory dentures showed one or more signs suggestive of Xerostomia. The majority of xerostomic participants with different sets of complete dentures were dissatisfied with oral functions (p < 0.05). There was a significant association between dry mouth and increasing age, female gender and smoking status (p < 0.05). CONCLUSION Among complete denture wearers, Xerostomia is significantly more prevalent in women and associated with increased age and smoking. Xerostomia adversely affects oral functions and overall satisfaction with dentures.
