If food residues on tooth surfaces cannot be removed by natural self-cleaning mechanisms that this is likely to lead to an increase dental plaque formation and the risk of dental, periodontal and general diseases. It was the aim of this study to assess oral health, oral hygiene with the influence of handedness and oral health related quality of life in patients with chronic peripheral FP. This study included 86 people. Patients with FP (n = 43) in an FP-group (FPG) were matched with 43 participants without ever diagnosed FP in a control group (CG). Oral health and oral hygiene were assessed in a clinical examination performed in hospital. Decayed-missing-filled-teeth-index, periodontal-screening-index, approximal plaque index and sulcus bleeding index were used to evaluate dental caries and periodontal health status. Oral health-related quality of life data (OHQoL) was collected with the Oral health impact profile (Germany-14) by interview. Oral health parameters in the FPG were significantly worse than in the CG. The median revealed 14.3% more proximal plaque (p = 0.014), 20.8% more sulcus bleeding (p = 0.002) and more than twice as much caries (p = 0.024). The paretic side compared to the non-paretic side of patients was significantly more affected by inflammatory periodontal diseases (p = 0.032) and had a higher prevalence of caries (p = 0.163). Right-handed patients with right-sided FP performed worse than right-handed patients with left-sided FP (p = 0.004). Patients with FP described a greater limitation of OHQoL than patients without this disease (p &lt; 0.001). In conclusion, facial nerve palsy affects oral health, oral hygiene and OHQoL of patients while handedness influences oral hygiene and oral health.<\/jats:p>","DOI":"10.1371\/journal.pone.0276152","type":"journal-article","created":{"date-parts":[[2022,11,17]],"date-time":"2022-11-17T14:13:18Z","timestamp":1668694398000},"page":"e0276152","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":8,"title":["Oral health and oral health-related quality of life in patients with chronic peripheral facial nerve palsy with synkineses\u2014A case-control-study"],"prefix":"10.1371","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0536-5730","authenticated-orcid":true,"given":"Lisa","family":"Strobelt","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anna-Maria","family":"Kuttenreich","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gerd Fabian","family":"Volk","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carien","family":"Beurskens","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas","family":"Lehmann","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ina Manuela","family":"Sch\u00fcler","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"340","published-online":{"date-parts":[[2022,11,17]]},"reference":[{"issue":"10","key":"pone.0276152.ref001","doi-asserted-by":"crossref","first-page":"2488","DOI":"10.1007\/s00415-019-09387-w","article-title":"Differential diagnosis of Peripheral facial nerve palsy: a retrospective clinical, MRI and CSF-based study","volume":"266","author":"J Zimmermann","year":"2019","journal-title":"J Neurol"},{"issue":"11","key":"pone.0276152.ref002","first-page":"1048","article-title":"Peripheral facial paralysis: etiology, diagnosis and treatment","volume":"30","author":"S Santos-Lasaosa","year":"2000","journal-title":"Rev Neurol"},{"key":"pone.0276152.ref003","first-page":"68","volume-title":"Neuroanatomie: Struktur und Funktion [Neuroanatomy: structure and function]","author":"M.
