The objective of this single-center prospective study is to evaluate the impact of periodontal treatment on masticatory performance in patients with periodontitis.
Participants will be asked to complete several questionnaires related to their oral health and quality of life. Functional masticatory tests and salivary flow measurements will also be performed.
Patients treated at the university hospital and diagnosed with periodontitis
Adult patients who have provided informed consent
Patients enrolled in a social security system
Patients who speak and understand French.
Minors
Pregnant or breastfeeding patients
Patients under legal protection or conservatorship
Patients who refuse to participate in the study
Single group
Functionnal test
Other interventionAdministration of questionnaires, functional masticatory test, and saliva collection.
The patient's masticatory performance score
The patient's masticatory performance score, obtained from the masticatory performance test (two-color chewing gum test) (quantitative variable).
Severity of periodontal disease assessed by stage.
Periodontitis is defined according to two criteria: grade and stage. The latter is used to characterize the severity of periodontal involvement. The stage of periodontitis is determined according to a four-level classification system, ranging from Stage 1 (low) to Stage 4 (high).
Salivation
Salivary flow is measured by collecting saliva at rest and after stimulation in mL/min. Stimulated salivary flow is assessed after chewing paraffin for 1 minute. The XI questionnaire (Xerostomia Inventory), proposed by Thomson et al. and validated in French, will also be administered (6,7). The XI consists of 11 items. Each item is scored on a scale of 1 to 5 to indicate how frequently the described situation occurs for the patient. The scores for each item are added together to yield a total score ranging from 11 (no dry mouth) to 55 (extreme dry mouth).
Swallowing
Oropharyngeal dysphagia is assessed using the EAT-10 (Eating Assessment Tool) questionnaire, which has been validated in French. The questionnaire comprises 10 items designed to assess swallowing disorders and the patient's perception of oropharyngeal dysphagia. Each item is rated on a 5-point scale ranging from 0 (no difficulty) to 4 (severe difficulty), resulting in a total score ranging from 0 to 40. A total score of 3 or higher indicates difficulty swallowing safely.
