Temporomandibular Disorders in Prospective Orthodontic Patients
Objectives: This study determined the prevalence and severity of Temporomandibular disorders (TMDs) in prospective Southeast Asian orthodontic patients. It also examined the association between TMDs and malocclusion severity as well as the impact of TMDs on oral health-related quality of life (OHRQoL).
Methods: Three hundred and fifty consecutive patients seeking orthodontic treatment were invited to participate in the study. Presence of TMDs was established with the Fonseca Anamnestic Index (FAI), whilst malocclusion severity and OHRQoL was evaluated with the Peer Assessment Rating (PAR) index and Oral Health Impact Profile–14 (OHIP-14) respectively. Data were analysed using Chi-square, Kruskal-Wallis, Mann-Whitney U tests, and Spearman’s rho correlation (p<0.05).
Results: Of the 350 consecutive patients, 164 (46.86%) consented to participation. Data from 26 participants were excluded due to incomplete entries, and that from 138 subjects (mean age 21.02 ± 5.45 years) were examined. TMD-related symptoms were present in two-thirds of the subjects with 20.3% experiencing moderate/severe TMDs. While no significant difference in PAR scores were observed between the “no TMDs” and “with TMDs” groups, subjects with TMDs had significantly higher OHIP-14 summary/domain scores than those without. Although a moderately strong correlation was observed between FAI and summary OHIP-14 scores (rs=0.57), no affiliation was observed between FAI and PAR scores.
Conclusions: The prevalence of TMD-related symptoms in prospective orthodontic patients was high, emphasizing the importance of screening the masticatory system before initiating orthodontic therapy. Though the presence of TMDs was not associated with malocclusion severity, it had a significant negative impact on OHRQoL.
