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.<\/jats:p><\/jats:sec><jats:sec><jats:title>Objective<\/jats:title><jats:p>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.<\/jats:p><\/jats:sec><jats:sec><jats:title>Databases and data treatment<\/jats:title><jats:p>A literature search (in PubMed, <jats:ext-link xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" xlink:href=\"http:\/\/embase.com\">Embase.com<\/jats:ext-link>, Web of Science [Core collection], and Cochrane Library) was performed on 20 January 2022, in collaboration with a medical librarian.

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.<\/jats:p><\/jats:sec>","DOI":"10.1002\/ejp.2031","type":"journal-article","created":{"date-parts":[[2022,9,5]],"date-time":"2022-09-05T17:29:07Z","timestamp":1662398947000},"page":"2036-2059","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":28,"title":["Orofacial pain and dysfunction in patients with Parkinson<b>'<\/b>s disease: A scoping review"],"prefix":"10.1002","volume":"26","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7861-5935","authenticated-orcid":false,"given":"Merel C.","family":"Verhoeff","sequence":"first","affiliation":[{"name":"Department of Orofacial Pain and Dysfunction, Academic Centre for Dentistry Amsterdam (ACTA) University of Amsterdam and Vrije Universiteit Amsterdam  Amsterdam The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4939-0321","authenticated-orcid":false,"given":"Michail","family":"Koutris","sequence":"additional","affiliation":[{"name":"Department of Orofacial Pain and Dysfunction, Academic Centre for Dentistry Amsterdam (ACTA) University of Amsterdam and Vrije Universiteit Amsterdam  Amsterdam The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sharine","family":"Tambach","sequence":"additional","affiliation":[{"name":"Department of Orofacial Pain and Dysfunction, Academic Centre for Dentistry Amsterdam (ACTA) University of Amsterdam and Vrije Universiteit Amsterdam  Amsterdam The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Denise","family":"Eikenboom","sequence":"additional","affiliation":[{"name":"Department of Orofacial Pain and Dysfunction, Academic Centre for Dentistry Amsterdam (ACTA) University of Amsterdam and Vrije Universiteit Amsterdam  Amsterdam The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2075-7495","authenticated-orcid":false,"given":"Ralph","family":"de Vries","sequence":"additional","affiliation":[{"name":"Medical Library Vrije Universiteit  Amsterdam The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Henk W.","family":"Berendse","sequence":"additional","affiliation":[{"name":"Amsterdam University Medical Centres (Amsterdam UMC) Vrije Universiteit Amsterdam, Neurology, Amsterdam Neuroscience  Amsterdam The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Karin D.","family":"van Dijk","sequence":"additional","affiliation":[{"name":"Amsterdam University Medical Centres (Amsterdam UMC) Vrije Universiteit Amsterdam, Neurology, Amsterdam Neuroscience  Amsterdam The Netherlands"},{"name":"Sleep Wake Centre Stichting Epilepsie Instellingen Nederland (SEIN)  Heemstede The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9877-7640","authenticated-orcid":false,"given":"Frank","family":"Lobbezoo","sequence":"additional","affiliation":[{"name":"Department of Orofacial Pain and Dysfunction, Academic Centre for Dentistry Amsterdam (ACTA) University of Amsterdam and Vrije Universiteit Amsterdam  Amsterdam The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2022,9,16]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.sleep.2013.04.021"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00702\u2010012\u20100768\u20100"},{"issue":"4","key":"e_1_2_9_4_1","first-page":"125","article-title":"Jaw and finger movements during visual and auditory motor tracking in Parkinson disease","volume":"12","author":"Adams S.","year":"2004","journal-title":"Journal of Medical Speech\u2010Language Pathology"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jns.2018.06.022"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.4103\/0028\u20103886.325323"},{"key":"e_1_2_9_7_1","doi-asserted-by":"publisher","DOI":"10.1590\/2317\u20101782\/20162015057"},{"issue":"2","key":"e_1_2_9_8_1","first-page":"63","article-title":"Evaluating dental status and prosthetic need in relation to medical findings in Greek patients suffering from idiopathic Parkinson's disease","volume":"10","author":"Anastassiadou V.","year":"2002","journal-title":"The European Journal of Prosthodontics and Restorative Dentistry"},{"key":"e_1_2_9_9_1","doi-asserted-by":"publisher","DOI":"10.3233\/JPD\u2010212605"},{"key":"e_1_2_9_10_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600\u20100722.2010.00802.x"},{"key":"e_1_2_9_11_1","doi-asserted-by":"crossref","unstructured":"Bandini A.
