INCIDENCE AND IMPACT OF LIMITED MOUTH OPENING ON THE QUALITY OF LIFE AND HEALTH MEASURED THROUGH GTQ INDEX
Limited mouth opening affects many essential functions of daily life, such as chewing, swallowing, speaking and maintaining effective oral hygiene. The aim of this study was to investigate how limited mouth opening affects the quality of life and mental health in patients with oral sub mucous fibrosis, infection, ankylosis, TMD and post-extraction measured through “Gothenburg trismus questionnaire”. A cross-sectional study was conducted at Fatima Jinnah Dental College and Hospital (FJDC&H). The sampling technique was convenience. The sample size of 70 patients was calculated at 95% confidence interval and 5% margin of error using OpenEpi software. The GTQ comprises 21 items of which it divided into jaw problems, eating problems, facial pain, lifestyle problems, and inter-incisal distance. The duration of the study was from Jan 2020 to Dec 2020. A verbal consent was taken from the participants. The ethical approval was obtained from the institutional ERC. As per the GTQ, jaw related issues were significantly associated with oral submucous fibrosis (p=0.031) and temporomandibular disorders (p=0.05). The eating and lifestyle changes were significant affecting the routine of those patients who were suffering from temporomandibular disorders (p =0.037, 0.043). The domain of facial pain was related to odontogenic infection (p=0.05) and not with any other cause of limited mouth opening. It is necessary to diagnose the accurate etiology of limited mouth opening (trismus) in those patients, who reported to the out-patient department with this complaint for its effective and complete management; also to improve patient’s quality of life.
