This is a prospective interventional clinical study whose main objective is to determine the impact of oral hygiene guidance on the oral health status of patients with Parkinson disease

Caries and periodontitis are infectious diseases that can eventually lead to the loss of the dental organ. The masticatory deficit engendered will have repercussions on the general state of the subject and on his quality of life (pains, difficulties of feeding which can cause nutritional deficiencies ...). The systematic review of the literature, despite low levels of evidence, shows that there is an influence of Parkinson's disease on oral health. Our goal is therefore to determine the impact of implementing appropriate oral hygiene measures on improving the quality of life of patients with Parkinson's disease.

This is a 40-patient, interventional, preliminary study that will rely on indicators of oral health status (DMF, Periodontal Index, presence of pathogenic bacteria), as well as a questionnaire measuring impact of oral conditions on patient well-being (OHIP-14). These data will be collected before and after the implementation of the hygiene measures, within a period of 6 months.
