Effect of Lip-seal Resistance Training on Lip-seal Strength in Young Adults

Lip-seal strength is important for articulating bilabials, capturing food during eating, maintaining fluid within the oral cavity before swallowing, and achieving swallowing pressure. The objective of this study was to investigate effect lip-seal resistance training on in young adults. participants comprised 15 healthy adults aged 26–34 years, all with complete dentition. Each required perform 5 weekdays a week 4 weeks commercially available instrument that purpose. placed midline, left corner, right corner mouth, pulled forward, leftward, rightward, respectively. were pull forcefully while resisting by closing lips together as strongly possible until exited lips. measured at after using measurement device. Change between analyzed Wilcoxon signed rank test. mean 8.9±1.5 N 10.4±1.8 after. A significant difference observed (p=0.003), increase period 18.1±17.6%. results showed increased These findings suggest involves pulling not only forward direction, but also bilateral directions stimulates orbicularis oris muscle, resulting an strength.
