Summary

This study investigates mouth cancer patients who use a special plate called an obturator to help them swallow. Tongue strength and biting force will be measured and compared to daily dietary intake. Results will provide a better understanding of how to improve eating ability and overall quality of life.

Detailed description

For oral cancer patients who have undergone maxillectomy, the use of an obturator can help restore partial swallowing function, thereby improving quality of life. Measuring tongue pressure provides insight into the extent of a patient's swallowing function, while occlusal pressure measurement assesses occlusal force, offering guidance for dietary modifications. This study will utilize a tongue pressure measurement device and occlusal pressure Prescale film to quantify tongue elevation pressure and occlusal force in post-maxillectomy oral cancer patients who wear obturators. This will be complemented by questionnaires to understand the participants' daily dietary habits and content. The aim is to establish the distribution of tongue and bite pressures within this patient population and to preliminarily determine the correlation between these pressures and daily diet
