Evaluation of the Impact of Periodontitis and Its Treatment on Swallowing Functions and Oral Quality of Life

Evaluation of the Impact of Periodontitis and Its Treatment on Swallowing Functions and Oral Quality of Life

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.

The questionnaires administered are as follows:

• the EAT-10 (Eating Assessment Tool), used to assess swallowing disorders and the patient's perception of oropharyngeal dysphagia;
• the XI (Xerostomia Inventory), used to evaluate xerostomia;
• the GOHAI (General Oral Health Assessment Index), used to assess the impact of oral health status on patients' quality of life.

The functional test (masticatory performance "chewing gum" test) will be performed at each visit if applicable (T0, T1, T2) to evaluate the impact of periodontal treatment on masticatory function. The two-colour chewing gum test is a commonly used method for assessing masticatory mixing ability.

Saliva collection for salivary flow analysis will also be performed at each follow-up visit in order to evaluate the impact of periodontal treatment on salivary function.
