ABSTRACT
Background: Parkinson's disease (PD) is one of the leading neurological disorders, affecting more than 6 millionpeople worldwide. These patients present motor and non-motor symptoms, including oral pathology. The objective of this research is to determine the oral health of patients diagnosed with PD, in order to stablish a specificpreventive oral health programme.Material and Methods: Case-control study on 104 PD and 106 control patients. The pre-designed clinical protocolincluded a complete oral examination on general aspects, standardised epidemiological index for caries, periodontal disease and edentulism, analysis of oral hygiene, presence of mucous/ salivary/ functional disorder, anddental treatments.Results: A higher number of PD patients consumed daily sweets (p<0.004) and antidepressant drugs (p<0.004).Patients with PD practised less interdental hygiene (p<0.023). The mean plaque index was higher in PD (p<0.003).Drooling (p<0.001), xerostomia (p<0.001), hyposialia (p<0.001), dysphagia (p<0.001), hypogeusia/dysgeusia(p<0.025) and chewing difficulty (p<0.006) were more common in PD.Conclusions: Oral disorders are frequent in PD. A good knowledge of these alterations will allow us design a specific preventive protocol. Some oral alterations may be a sign of diagnostic alert or progression of PD. (AU)

BACKGROUND: The aim of the study was to analyze the histopathological characteristics of samples with a diagnosis of oral lichenoid disease (OLD) and their link with the location and the type of clinical lesion, and the clinicopathological subtypes. MATERIAL AND METHODS: Retrospective study on 85 consecutive patients diagnosed with OLD (58 women and 27 men, mean age of 57.7 years). Clinical and histopathological characterization of each case (modified WHO criteria). Collection of the clinical and histopathological data of the lesions. Descriptive and comparative statistical analysis of the results. RESULTS: The 78.8% of the cases were considered clinically typical while the 21.2% were considered compatible. Histologically, 52.9% were classified as typical and 47.1% as compatible. Biopsies from 'plaque-like' lesions presented hyperkeratosis (p < 0.001) and epithelial dysplasia (p = 0.06) more frequently. Furthermore, acute inflammation was more evident in erosive-ulcerative lesions (p = 0.001). Differences regarding the location of the biopsy were statistically non-significant. However, 42.9% of the tongue biopsies showed epithelial dysplasia. CONCLUSIONS: The histopathological aspect of this disorder is not specific and does not allow us to differentiate between the main subtypes. Therefore, the main reasons to perform a biopsy in this disorder are to define the differential diagnosis and to rule out epithelial dysplasia or a carcinoma. The final histopathological result may be subject to the type of lesion that is biopsied
