| Abstract | |
The oral motor system includes actions such as breathing, swallowing and chewing that can be committed by changes localized in specific regions of the body, interfering with the general health of the individual and consequently in the quality of life related to oral health. The aim of this study was to investigate the relationship between orofacial dysfunction, malocclusion and salivary cortisol levels with quality of life in young adults. The sample comprised 30 individuals, aged from 18 to 25 years old being 15 male and 15 female (22.93± 2.42 years), who were submitted to intra and extra-oral clinical examination for evaluation of orofacial conditions, including morphological occlusion. The presence of orofacial dysfunction was evaluated using the Nordic Orofacial Test - Screening (NOT-S) protocol and the quality of life related to oral health was assessed by a structured interview for the application of the Oral Health Impact Profile questionnaire (OHIP-49). For the salivary cortisol analyses, saliva samples were obtained during three days at two different times, at waking up and 30 minutes after and the difference between the two respective concentrations was considered (awakening cortisol response - ACR). The data were submitted to statistical analyses by Mann-Whitney test, Spearman's correlation and multiple linear regression analysis. The significance level adopted was ?=0.05. The variables NOTS and ACR (?g/dl) were dichotomized considering the median values (2.0 and 0.15 respectively). The results showed similar values for NOT-S scores and ACR between males and females (p>0.05). The individuals with malocclusion had scores of "psychological discomfort" domain of OHIP-49 significantly higher than individuals with normocclusion (2.6±3.5 and 0.1±0.4, respectively); those with scores of NOT-S above the median presented values of "physical pain" domain of OHIP-49 significantly higher than the individuals with scores bellow or equal to the median (6.8± 4.4 and 3.5 ± 3.3, respectively). Significant correlations were found between the OHIP-49 domains "physical pain" (r=0.43, p=0.016) and "physical disability" (r=0.36, p=0.046) and NOT-S scores. In multiple linear regression analysis, statistically significant values were observed between NOT-S and OHIP-49 (r2=0.137, p=0.018) and five of their domains, including physical pain (p=0.014), physical disability (p=0.009), psychological disability (p=0.034), social disability (p=0.025) and handicap (p=0.023), with coefficient of determination (r2) ranging from 0.09 to 0.15, demonstrating influence of orofacial dysfunction in the oral health quality of life in the range of 8 to 15%. There was not the same association with the salivary cortisol levels. It can be concluded that individuals with orofacial dysfunction (higher scores of the NOTS) presented impairment in oral health quality of life, but not enough to increase salivary cortisol levels. Furthermore, the other variables, such as gender, age, and malocclusion did not have influence on oral health quality of life in the studied sample (AU) | |
