INFLAMMATION, SECONDARY, GINGIVITIS
The main objective is to test the hypothesis that gingivitis reduction via optimized daily oral hygiene and antibacterial chlorhexidine-containing (CHX) mouth rinsing improves lung function in terms of forced vital capacity (FVC), as an indicator of lung volume, by at least 2%. This allows interpreting the changes in lung function as direct or indirect consequences of changes in oral inflammation.As a secondary objective, we test the hypothesis that gingivitis reduction by improved oral hygiene and CHX mouth rinsing improves forced expiratory volume in 1 s (FEV
