Evaluation of temporomandibular disorder symptoms and oral health-related quality of life in adolescent orthodontic patients with different dental malocclusions

ABSTRACT Objective: To estimate the prevalence of temporomandibular disorders in adolescent orthodontic patients with different dental malocclusions and to assess the relationship between oral health-related quality of life. Methods: This study was carried out on 648 randomly selected individuals 14–19 years of age. Diagnostic Criteria for Temporomandibular Disorders (DC/TMD), Fonseca Questionnaire, and Oral Health Impact Profile-14 (OHIP-14) forms were used. Results: The GCPS, TMD Pain, Fonseca, OHIP-14, PHQ-9, GAD-7, OBC, and PHQ-15 mean scores of female participants were statistically significantly higher than males (p < 0.05).There was a significant difference among the malocclusion groups in terms of their mean scores in GCPS, Fonseca, and OHIP-14 (p < 0.05).The age values and JFLS, TMD Pain, Fonseca, OHIP-14, PHQ-9, GAD-7, and PHQ-15 were statistically significant correlations in the positive direction. Conclusion: The DC/TMD form allows both a physical assessment of Axis I and II that examines psychosocial status and pain-related disorders and a more comprehensive assessment. The mean OHIP-14 and Fonseca questionnaire scores of Class III groups were found to be significantly higher.
