Personal scoping review: A novel review type with a personal touch.

BACKGROUND: The importance of incorporating patient and medical professional perspectives in medical research is increasingly recognized. However, formal platforms for these voices are limited. OBJECTIVE: To address this gap, this study proposes a novel manuscript type, the Personal Scoping Review, within the Journal of Oral Rehabilitation. MATERIALS AND METHODS: Personal Scoping Reviews utilize a qualitative design with semi-structured interviews to gather patient and professional perspectives. This approach offers flexibility and depth, allowing authors to explore diverse insights. The reviews focus on care, education and research agendas related to the topic, using the voices of individuals as primary evidence. RESULTS & CONCLUSION: Personal Scoping Reviews highlight concerns in patient care, educational needs and research gaps, offering a comprehensive view. By integrating diverse perspectives, these reviews provide valuable insights for improving medical research and practice. They facilitate the formulation of agendas to address key issues in care, education and research. By amplifying individual perspectives, these reviews aim to enhance the relevance and impact of research, ultimately benefiting patients and healthcare providers alike.

A personal exploration of oral health in Parkinson's disease through the eyes of a multifaceted authority.

BACKGROUND AND OBJECTIVE: Parkinson's disease (PD) poses a range of challenges, including oral health issues, that significantly impact the patient's quality of life. Despite growing awareness of PD, oral health receives limited attention. To shed light on this matter, this personal scoping review explores the perspectives of Professor K.G. Raphael, who is both a professional and a PD patient, on various aspects of oral health in PD. METHODS: Through semi-structured interviews, Prof. Raphael shares her insights on the complexities of oral health as a PD patient to compose an agenda for oral health care, research, and education, for PD patients. RESULTS: She emphasises the importance of interdisciplinary collaboration and education. Additionally, Prof. Raphael identifies crucial research areas, such as exploring the role of the oral microbiome and assessing the impact of exercise on oral health in PD. CONCLUSION: This study resulted in agendas to improve oral health care, research and education, advocating for a holistic approach to enhance PD patients' well-being. Despite its limitations, this study highlights the imperative of integrating oral health into the broader management of PD, emphasising interdisciplinary collaboration and patient empowerment.

The bruxism screener (BruxScreen): Development, pilot testing and face validity.

BACKGROUND: To assess awake and sleep bruxism, the Standardised Tool for the Assessment of Bruxism (STAB) is currently being developed. The STAB will be a comprehensive tool for the detailed assessment of bruxism behaviour itself as well as of its possible consequences, causes, and comorbid conditions. OBJECTIVE: Since the STAB cannot fully meet the 'A4 principle' for a bruxism assessment tool, i.e., being Accurate (reliable and valid), Applicable (feasible), Affordable (cost-effective), and Accessible (suitable for everyday clinical use), the Bruxism Screener (BruxScreen) has been developed to be used in large-scale epidemiological research projects and, especially, in general, dental practices. METHODS: The BruxScreen consists of two parts: a questionnaire (BruxScreen-Q) to be completed by patients, and a clinical assessment form (BruxScreen-C) to be completed by dentists. RESULTS: This paper describes the development of the BruxScreen and provides the outcomes of the pilot testing phase and the face validity assessment (i.e. that the first impressions of the tool indicate that it adequately reflects the construct to be measured). CONCLUSION: The resulting BruxScreen is considered ready for more profound psychometric testing in the general dental setting.

Self-reported oral moistening disorders in obstructive sleep apnoea: A scoping review.

BACKGROUND: Obstructive sleep apnoea (OSA) is a highly prevalent problem with significant consequences. Continuous positive airway pressure (CPAP) and oral mandibular advancement device (MAD) are considered the standard treatments for OSA. Patients may experience self-reported oral moistening disorders (OMDs) (i.e. xerostomia or drooling) at the beginning, throughout and after treatment. This affects oral health, quality of life and treatment effectiveness. The exact nature of the associations between OSA and self-reported OMD is still unknown. We aimed to provide an overview of the associations between self-reported OMD on the one hand and OSA and its treatment (namely CPAP and MAD) on the other hand. In addition, we sought to determine whether OMD affects treatment adherence. MATERIALS AND METHODS: A literature search in PubMed was performed up to 27 September 2022. Two researchers independently assessed studies for eligibility. RESULTS: In total, 48 studies were included. Thirteen papers investigated the association between OSA and self-reported OMD. They all suggested an association between OSA and xerostomia but not between OSA and drooling. The association between CPAP and OMD was addressed in 20 articles. The majority of studies have indicated xerostomia as a CPAP side effect; however, some have observed that xerostomia diminishes with CPAP therapy. In 15 papers, the association between MAD and OMD was investigated. In most publications, both xerostomia and drooling have been described as common side effects of MADs. These side effects are often mild and transient, and they improve as patients continue to use their appliance. Most studies found that these OMDs do not cause or are not a strong predictor of non-compliance. CONCLUSION: Xerostomia is a common side effect of CPAP and MAD, as well as a significant symptom of OSA. It may be regarded as one of the indicators of sleep apnoea. Moreover, MAD therapy can be associated with OMD. However, it seems that OMD may be mitigated by being adherent to the therapy.

Are demographic factors, masticatory performance and structural brain signatures associated with cognitive impairment in older people? A pilot study of cross-sectional neuroimaging data.

BACKGROUND: The occurrence of cognitive impairment (CI) is expected to increase within an ageing population. CI is associated with tooth loss, which influences masticatory performance. A decrease in masticatory performance may cause functional and morphological changes in the brain. However, whether CI is associated with masticatory performance, demographics, and structural brain signatures has not been studied yet. OBJECTIVES: To assess the associations between CI on the one hand, and masticatory performance, demographic factors, and structural brain signatures (i.e. cortical volume and thickness) on the other hand. METHODS: In total, 18 older adults with CI (mean ± SD age = 72.2 ± 9.5 years) and 68 older adults without CI (65.7 ± 7.5 years) were included in this study. Masticatory performance was quantified using a colour-changeable chewing gum. A Magnetic Resonance Imaging (MRI) scan was used to map structural brain signatures. To study our aim, a multivariate binary logistic regression analysis with backward selection was performed. RESULTS: The cortical volume of the right entorhinal cortex was negatively associated with CI (p < .01). However, demographic factors, masticatory performance, and the other structural brain signatures under investigation were not associated with CI. CONCLUSION: A decrease in the volume of the right entorhinal cortex is associated with CI in older people.

Translation and cultural adaptation of the Standardized Tool for the Assessment of Bruxism (STAB) and the Bruxism Screener (BruxScreen): A 12-step guideline.

BACKGROUND: Recently, the Standardized Tool for the Assessment of Bruxism (STAB) and the bruxism screener (BruxScreen) have been developed for use in research and clinical settings. OBJECTIVE: As to ascertain high-quality use of both instruments worldwide, it was our aim to develop a guideline for the translation and cultural adaptation of the STAB and the BruxScreen. METHODS AND RESULTS: This paper describes a 12-step guideline for the translation and cultural adaptation of the STAB and the BruxScreen. A format of a translation log is provided as well. Besides, a website has been created for the guidance of translation teams. CONCLUSION: Following the 12 steps, new language versions of the STAB and the BruxScreen will be ready for further testing (reliability, validity, responsiveness and interpretability) and, ultimately, application in research and clinics around the world.

Towards an operational definition of oral frailty: A e-Delphi study.

OBJECTIVES: Building upon our recently developed conceptual definition of oral frailty (the age-related functional decline of orofacial structures), this e-Delphi study aims to develop an operational definition of oral frailty by identifying its components. METHODS: We used a modified e-Delphi study to reach a consensus among international experts on the components of oral frailty. Twelve out of fifteen invited experts in the field of gerodontology participated. Experts responded to three rounds of an online 5-point scale questionnaire of components to be included or excluded from the operational definition of oral frailty. After each round, scores and rationales were shared with all experts, after which they could revise their position. A consensus was reached when at least 70% of the experts agreed on whether or not a component should be included in the operational definition of oral frailty. RESULTS: The experts achieved a high level of agreement (80 - 100%) on including eight components of oral frailty and excluding nineteen. The operational definition of oral frailty should include the following components: 1) difficulty eating hard or tough foods, 2) inability to chew all types of foods, 3) decreased ability to swallow solid foods, 4) decreased ability to swallow liquids, 5) overall poor swallowing function, 6) impaired tongue movement, 7) speech or phonatory disorders, and 8) hyposalivation or xerostomia. CONCLUSION: This e-Delphi study provided eight components that make up the operational definition of oral frailty. These components are the foundation for the next stage, which involves developing an oral frailty assessment tool.

Clinicians' view on the management of oral health in Parkinson's disease patients: a qualitative study.

BACKGROUND: due to numerous motor and non-motor symptoms, dental treatment in patients with Parkinson's Disease (PD) can be challenging. Knowledge regarding optimal management of oral health in PD patients is lacking. AIM: to gain a deeper understanding of the experiences of dentists regarding oral health care for PD patients in the Netherlands. MATERIAL AND METHOD: semi-structured interviews were conducted with (specialized) dentists working with PD patients. A thematic analysis was performed using a framework-based approach. RESULTS: ten dentists were interviewed. They reported that dental care in PD patients requires 1) adaptation of timing and length of treatments and consultations, and 2) intensifying preventive measures. Dentists experienced the organization as bureaucratic and difficult. Moreover, differences between being institutionalized or living at home were present. Education and research are needed to improve PD patients' oral health. The experience level and affinity for treating PD patients positively influences confidence levels of the practitioner. Finally, points of improvement were suggested. CONCLUSION: managing oral health in PD patients is challenging, and interdisciplinary collaboration is needed to overcome difficulties. Reducing the bureaucratic burden and improving knowledge could help and stimulate oral health care providers to treat PD patients more effectively and, consequently, improve their oral health.

Dental practitioner approaches to bruxism: Preliminary findings from the national dental practice-based research network.

OBJECTIVE: Bruxism is a repetitive masticatory muscle activity. This study investigates dental practitioners' approaches to bruxism assessment and treatment in practices. METHODS: A brief 5 question questionnaire ("Quick Poll") on bruxism was conducted. RESULTS: A total of 397 practitioners responded. More than half (55%) initiated treatment for bruxism on one to three patients per month. The majority believed that stress (97%) and sleep patterns (82%) affected bruxism in their patients. Interestingly, 96% offered an occlusal guard/appliance and 46% made occlusal adjustments. CONCLUSION: This study highlights inconsistencies in practitioner approaches to bruxism assessment and management in clinical settings, suggesting gaps in practitioner knowledge evidenced by the varied responses.

Parkinson's disease and oral health: A systematic review.

OBJECTIVE: in patients with Parkinson's Disease (PD), oral health can be affected by motor and non-motor symptoms and/or medication use. Therefore, the aim was to systematically review the literature on oral health and associated factors of oral health in PD patients. DESIGN: a literature search was performed from inception up to April 5th, 2023. Original studies that assessed oral health-related factors in PD patients and were written in English or Dutch, were included. RESULTS: 11276 articles were identified, of which 43 met the inclusion criteria (quality range poor-good). A higher prevalence of dental biofilm, bleeding/gingivitis, pocket depth (≥4 mm), tooth mobility, caries, and number of decayed missing filled teeth/surfaces was found in PD patients than in controls. However, no difference between both groups was found when analysing edentulism and wearing dentures. Poor oral health of PD patients was associated with a longer disease duration, higher disease severity, and more prescribed medications. CONCLUSIONS: oral health of PD patients is worse than that of healthy individuals. It is associated with the duration and severity of PD and medication use. Therefore, we advise regular appointments with oral health care professionals, with an important focus on prevention.

Salivation in Parkinson's disease: A scoping review.

OBJECTIVES: We aimed to provide an overview of the available literature that includes both objective assessments (namely hypersalivation and hyposalivation) and the subjective experience (namely xerostomia and drooling) of salivary problems in patients with Parkinson's disease. BACKGROUND: In patients with Parkinson's disease, there may be complaints of salivary problems such as xerostomia or drooling. This can have consequences for their oral health and quality of life. To date, systematic reviews have focused on drooling only. MATERIALS AND METHODS: A literature search in 4 databases was performed up to 12 February 2021. Two researchers independently assessed studies for eligibility. RESULTS: In total, 63 studies were included. The prevalence of self-reported xerostomia ranged from 49% to 77%, and that of self-reported drooling ranged from 5% to 80%. Ten articles reported a significantly lower mean salivary flow in patients with Parkinson's disease than in controls. None of the articles with both a control group and a patient group reported a significantly higher salivary flow in patients with Parkinson's disease. When questioned about subjective salivary problems, a significantly higher prevalence of both xerostomia (7 studies) and drooling (14 studies) was found in patients with Parkinson's disease than in controls. Patients with Parkinson's disease have a lower salivary flow rate and higher prevalence of both xerostomia and drooling than controls. CONCLUSION: The complexity of salivary problems present in patients with Parkinson's disease necessitates a multidisciplinary approach in order to avoid mutually counteracting treatments from different healthcare professionals.

Orofacial pain and dysfunction in patients with Parkinson's disease: A scoping review.

BACKGROUND: Parkinson's disease (PD) is commonly known as a disorder that affects the smooth performance of body movements. In addition to the motor impairments, patients with PD often experience pain. Both motor impairments and pain can occur throughout the body, hence including the orofacial region. However, currently, there is a lack of knowledge on the orofacial manifestations. Since orofacial pain and dysfunction can, amongst others, reduce the quality of life of patients with PD, it is important to explore the prevalence of these symptoms in the PD population. OBJECTIVE: To provide a broad overview of the relevant literature on orofacial pain and dysfunction in patients with PD. Furthermore, we aim to generate hypotheses for future research on this topic. DATABASES AND DATA TREATMENT: A literature search (in PubMed, Embase.com, Web of Science [Core collection], and Cochrane Library) was performed on 20 January 2022, in collaboration with a medical librarian. In total, 7180 articles were found, of which 50 were finally included in this scoping review. RESULTS: In the included studies, pain (e.g. orofacial pain (N = 2) and temporomandibular disorder pain (N = 2)), orofacial motor dysfunction (e.g. limited jaw movements (N = 10), reduced maximum muscle output (N = 3), chewing difficulties (N = 9), unspecified TMD (N = 3), sensory disturbances (N = 1)), and bruxism (N = 3) were observed more often in patients with PD than in healthy controls. CONCLUSION: Patients with PD experience more pain in the orofacial area and more dysfunction of the masticatory system than their healthy peers. SIGNIFICANCE: This scoping review can increase health care providers' awareness of the problems that can be encountered in the orofacial area of PD patients, especially pain syndromes also occur in the orofacial region and not only in the extremities. Besides, dysfunction of the orofacial area is elaborated in this scoping review, which helps to understand that this limits PD patients' quality of life. Further, the outcomes of this scoping review can assist in encouraging collaboration between medicine and dentistry. Finally, this scoping review suggests new research areas, based on the gaps identified in the current literature on this topic. Ultimately, this will improve individualized strategies for reducing orofacial pain and/or dysfunction in PD patients.

Oral health-related quality of life in patients with Parkinson's disease.

BACKGROUND: Parkinson's disease (PD) is a neurodegenerative condition affecting the quality of life. Due to a worsening of oral health in PD patients with the progression of the disease, oral health-related quality of life (OHRQoL) could be impaired as well. OBJECTIVES: To assess whether PD patients in The Netherlands experience worse OHRQoL than historical controls, and to investigate which factors are associated with OHRQoL in PD patients. MATERIALS & METHODS: In total, 341 PD patients (65.5 ± 8.4 years) and 411 historical controls (62.6 ± 5.3 years) participated. Both groups completed a questionnaire. The PD patients were asked questions regarding demographics, PD, oral health, and OHRQoL. The historical controls filled in demographic information and questions regarding OHRQoL. The latter construct was assessed using the Dutch 14-item version of the Oral Health Impact Profile (OHIP-14). Data were analysed using independent samples t-tests and univariate and multivariate linear regression analysis. RESULTS: The mean OHIP-14 score was higher in PD patients (19.1 ± 6.7) than in historical controls (16.5 ± 4.4) (t(239) = 6.5; p < .001). OHRQoL in PD patients was statistically significant associated with motor aspects of experiences of daily living (B = 0.31; t(315) = 7.03; p < .001), worsening of the oral environment during disease course (B = 3.39; t(315) = 4.21; p < .001), being dentate (B = -5.60; t(315) = -4.5; p < .001), tooth wear (B = 2.25; t(315) = 3.29; p = .001), and possible burning mouth syndrome (B = 5.87; t(315) = 2.87; p = .004). CONCLUSION: PD patients had a lower OHRQoL than historical controls. Besides, PD-related variables and oral health-related variables were associated with OHRQoL.
