Influence of the COVID-19 pandemic on pain and oral health-related quality of life in women with temporomandibular disorder.

ABSTRACT

OBJECTIVE: This study aimed to evaluate and compare pain intensity and Oral Health-related Quality of Life (OHRQoL) in women with temporomandibular disorder (TMD) before (T1) and during (T2) COVID-19 pandemic. MATERIALS AND METHODS: Sample was composed of forty-one female participants with painful TMD, who presented for TMD treatment. Subjects were asked to indicate their pain intensity and to answer the Oral Health Impact Profile-14 (OHIP-14). Participants data were collected twice T1 (evaluation of medical records fulfilled before COVID-19 pandemic) and T2 (by means of an online form). Socio-demographic data were assessed in T1. Statistical analysis was performed with a significance level of 5% (Wilcoxon, chi-square or Fisher's exact tests, multiple linear regressions). RESULTS: No difference was found in pain intensity (p=0.26) and OHIP-14 global scores (p=0.53). Physical pain (p=0.03) and social disability (p=0.05) domains improved. In T1, subject's occupation was associated with OHIP-14 global score, physical pain, and physical disability domains. In T2, age was associated with OHIP-14 global scores as well as physical pain, psychological discomfort, and psychological disability domains. CONCLUSION: COVID-19 pandemic did not worsen pain intensity and OHRQoL in women with painful TMD, and it is suggested that socio-demographic characteristics influenced TMD patients coping skills during pandemic.
