Study of Lip, Cheek, and Tongue Muscle Pressure Impact on Upper Jaw Width in Ages 12 to 25

What this Trial Is About

Researchers are investigating how pressures from the tongue, lips, and cheeks affect the development of a narrow upper jaw, known as maxillary constriction. This study aims to understand if different muscle pressure patterns contribute to this condition and how that knowledge might improve orthodontic treatment outcomes. It is a randomized clinical study involving patients aged 12 to 25 with skeletal Class I jaw alignment. Participants are divided into two groups those with a narrow upper jaw and those with normal jaw width. Using a device called the Iowa Oral Performance Instrument IOPI, researchers measure the strength and endurance of the tongue, lips, and cheeks by having participants press a small air-filled bulb in their mouths. These measurements are taken before any orthodontic treatment begins, including maximum tongue pressure and lip and cheek pressures, to compare muscle function between the groups. During the study, participants will undergo a series of pressure tests using the IOPI device, performed three times each with rest intervals. Researchers will assess muscle pressures in kilopascals and analyze the data to explore relationships between muscle forces and jaw width. The primary measurement is the maximum voluntary tongue pressure taken at baseline. This study involves no treatment interventions and focuses on diagnostic assessments to better understand the role of oral muscles in jaw development.
