PREVALENCE OF SIGNS OF TEMPOROMANDIBULAR DISORDERS IN HEALTHY ASYMPTOMATIC COMPLETELY EDENTULOUS INDIVIDUALS AND THE EFFECT OF DENTURE ON TEMPOROMANDIBULAR DISORDERS

Abstract

Background and objectives: Temporomandibular disorders (TMD) are a multi-factorial issue characterized by signs and symptoms that eventually restrict or may impede an edentulous patient’s physiological activity. The current study aimed to ascertain the prevalence of TMD among edentulous individuals, and their association with risk factors such as gender, age, educational level, habitual Khat chewing, economical status, duration of edentulousness, the age, and vertical dimension of occlusion (OVD) of the present dentures. Materials and Methods: This study involved a thorough evaluation of 400 edentulous Yemeni patients who were undergoing prosthetic treatment at the Faculty of Dentistry Sana'a University and the University of Sciences and Technology, 114 with denture and 286 without denture. This evaluation of TMD signs and symptoms was performed using the Helkimo index. The outcomes were analyzed by correlating the research variables and the prevalence of signs and symptoms of TMD using chi-squared tests. Results: The study’s findings showed that signs and symptoms of TMD were 82.5% and 55.3% among complete denture wearers and 80.4% and 49.0% among non-denture wearers, respectively. Furthermore, the most frequent sign and symptom was the joint sounds. This study revealed a statistically significant association between the prevalence of TMD symptoms and patient gender and between TMD signs and symptoms and OVD in denture wearers. Conclusion: The current study supports the need to evaluate the potential impact of TMD on completely edentulous individuals and to take caution while receiving dental therapy and prosthetic rehabilitation.
