Brief summary
The effect of periodontal disease on the general condition of patients remains today underestimated in Parkinson's disease. The BUCCO-PARK project aims to carry out an exploratory study of oral therapeutic education on the clinical evolution and fate of the microbiota of patients undergoing brain stimulation surgery. During the study, patients will follow the standard care pathway alone or combined with an oral therapeutic education. Biological samples will assess how the microbiota of these patients will be impacted. BUCCO-PARK aims to optimize the care of Parkinson's patients by integrating oral care.
Detailed description
Patients included will be randomized in one of both defined groups : experimental group, in which patients will receive an oral education or control group, in which patient only follow the traditional care pathway. Patients will be included in the trial before surgery after medical examination and life quality and oral environment evaluations. Oral therapeutic education for patients randomized in experimental group will be performed at inclusion, and 6, and 12 months after surgery. For all patients, an oral examination, an assessment of the quality of life and oral, fecal and blood samples will be carried out at inclusion, and 6 and 12 months after surgery.
Interventions
BEHAVIORALOral education
Oral therapeutic education aims to improve dietary practices, daily hygiene and care, in an approach adapted to the characteristics and consequences of Parkinson's disease. An oral prevention package will be given to patients. Initially, dentists expose various oral health problems commonly found in Parkinson's disease, in order to give patients the necessary information for the understanding Secondly, dentists dispenseront practical advice tailored to pathology, to maintain good oral health

| Caries index progression | 12 months | Assessment of dental state using caries index (from 1 : low risk to 3) at inclusion and 6 and 12 months after surgery. Carious index measuring the number of decayed teeth, absent for decay and closed in permanent toothing. |
| Plaque index progression | 12 months | Assessment of dental state using plaque index (from 0 : absence of microbial plaque to 3 : large amount of plaque in sulcus or pocket), at inclusion and 6 and 12 months after surgery. After all teeth are examined and scored, the index is calculated by dividing the number of plaque containing surfaces by the total number of available surfaces. |

| Papillary bleeding index progression | 12 months | Assessment of dental state using papillary bleeding index at inclusion and 6, and 12 months after surgery. The intensity of any bleeding is recorded as: Score 0 - no bleeding; to Score 4 - Profuse bleeding occurs after probing; blood flows immediately into the marginal sulcus. |
| Number of loss of attachment | 12 months | Assessment of dental state using number of loss of attachment at inclusion and 6, and 12 months after surgery. |

| NMSS score at inclusion | 1 month | Non Motor Symptoms Scale score at inclusion. Medical questionnaire with 30 items assessing symptoms progression. For each item, severity and frequency are assessed. Severity is assessed from 0 (no severity) to 3 and frequency from 1 (rare) to 4 |

| alpha diversity of microbiota | 12 months | alpha diversity is expressed as number of observed species of oral and intestinal microbiota at inclusion, and 6, and 12 months after surgery. Alpha diversity is defined by Whittaker (1972) as the species richness of a place. The higher the number, the higher the diversity. |
| beta diversity of microbiota | 12 months | beta diversity is relative bacterial abundance at different levels in percent at inclusion, and 6, and 12 months after surgery.
