Impact factors on oral health related quality of life in patients requiring orthognathic surgery

Resumo

Individuals with dentofacial deformities have a greater negative impact on oral health and in quality of life. The aim of this study was identified the main factors involved in the perception of the oral health related quality of life in individuals with dentofacial deformities. Material and methods: In a crosssectional study, were evaluated 72 individuals in preoperative period of orthognathic surgery at the Oral and Maxillofacial Surgery Service at Federal University of Paraná and at Positivo University. The age, gender, facial profile, presence or absence of asymmetry and temporomandibular disorders (TMD) symptoms were accessed. Through the Oral Health Impact Profile-14 (OHIP-14) the perceptions about oral health related quality of life of the patients was accessed. The TMD symptoms were evaluated with Fonseca anamnestic index. Data were submitted to descriptive and inferential statistical analysis with a significance level of 0.05. Results: The OHIP-14 mean score was higher with increasing age (p= 0.007), in females (p= 0.076), asymmetric patients (p= 0.030). and according to the increase in reported TMD symptoms (p= 0.001). Individuals with no TMD symptoms had an OHIP-14 mean of 8.86±8.06; individuals with mild TMD had a mean of 15±6.28, moderate TMD had a mean of 20.6 ± 9.44 and severe TMD had a mean of 26.42±7.66. There were no differences between OHIP-14 and type of facial profile (p= 0.725). Conclusion: It is concluded that increasing age, female gender, presence of asymmetry and the severity of TMD symptoms are important factors related to poor oral health related quality of life in individuals with dentofacial deformities.
