Do changes in oral health-related quality-of-life, facial pain and temporomandibular disorders correlate after treatment of severe malocclusion?

Abstract

Introduction. The aim was to evaluate the relationships of changes in facial pain, temporomandibular disorders (TMDs) and oral health-related quality-of-life (OHRQoL) in adults who underwent orthodontic or orthodontic/surgical treatment. Methods. Sixty-four patients (46 women, 18 men, range 18-64 years) with severe malocclusion and functional problems were treated in Oulu University Hospital. Of these, 44 underwent orthodontic-surgical and 20 orthodontic treatment. Data were collected with questionnaires and clinical stomatognathic examinations before and on average 3 years after treatment. The OHRQoL was measured with OHIP-14 (The Oral Health Impact Profile), the intensity of facial pain with the Visual Analogue Scale (VAS) and the severity of TMD with the Helkimo's anamnestic (Ai) and clinical (Di) dysfunction indices. Results. A significant improvement was found in facial pain, signs and symptoms of TMD and OHRQoL after the treatment (p < 0.05). The decrease in VAS was associated with improvement in OHIP-14 severity (r = 0.296, p = 0.019). The correlations between changes in OHIP-14 severity and Ai and Di were not statistically significant. Conclusion. Treatment of severe malocclusion seemed to improve OHRQoL via decreased facial pain. Decreased facial pain was associated especially with improved OHRQoL dimensions of physical pain, physical disability and social disability.

Correlation between oral health-related quality of life and clinical dysfunction index in patients with temporomandibular joint osteoarthritis

“…Pain can have various adverse effects on a person's physical condition (26). Therefore, it is understandable that changes in orofacial pain are related to changes in the OHRQoL domains of physical pain and physical disability, as was reported in a previous study (26). Interestingly, changes in HDI score and severity were correlated in the present study with changes in the domain of social disability, which includes irritability and difficulty performing usual tasks.…”

“…HDI encompasses orofacial pain and dysfunction due to TMJ. Pain can have various adverse effects on a person's physical condition (26). Therefore, it is understandable that changes in orofacial pain are related to changes in the OHRQoL domains of physical pain and physical disability, as was reported in a previous study (26).…”

“…Some studies reported positive correlations between the severity of TMD symptoms and OHRQoL (1,25); however, other studies found no such correlation (26). Therefore, we investigated whether the severity of signs and symptoms, as determined by the HDI, were correlated with OHRQoL in patients with TMJ OA.…”

Relationship between orthodontics and temporomandibular disorders

“…The orthognathic surgery in combination with orthodontic treatment have showen amelioration and favorable effects on TMJ and the masticatory functions [56][57][58] , as a significant reduction of myofascial pain, as well as an important resolution of the signs and symptoms of the TMJ [59][60][61] . However, a significant elimination of previous sounds from the TMJ, has not been observed 62 .…”

Integração da Psicologia e Odontologia na DTM: revisão sistematizada

“…Silvola et al 33 apontam que o tratamento da DTM, interdisciplinado com a psicoterapia, proporciona um melhor enfrentamento da dor e uma melhoria na qualidade de vida, uma vez que a DTM se estende para todo o contexto social, fisiológico e psicológico. Segundo o autor, a ação do psicólogo se estenderia a todas as dimensões prejudicadas, promovendo assim o restabelecimento da qualidade de vida.…”
