Abstract

Objective: This study aimed to evaluate the presence sleep bruxism, malocclusions and orofacial dysfunctions as well as the salivary levels of cortisol and alpha-amylase in asthmatic children. Material and Methods: The sample consisted of 108 children of both genders in the age-range from seven to nine years, selected from Policlinic Santa Teresinha Doutor Antonio Haddad Dib (asthma group, n=53) and from public schools (control group, n=55), both of Piracicaba, SP, Brazil. Sleep bruxism diagnosis was confirmed by parental report of grinding sounds (at least three times a week) and the presence of shiny and polish facets on incisors and/or first permanent molars. The Index of Orthodontic Treatment Need ¿ Dental Health Component (IOTN-DHC) was used for occlusion evaluation. Orofacial dysfunctions were evaluated using the Brazilian Portuguese version of the Nordic Orofacial Test-Screening (NOT-S). Salivary cortisol (?g/dl) and alpha-amylase (U/ml) were assayed using enzyme immunoassay kit. These data were expressed as ``awakening response¿¿ (AR), calculated as the difference between levels immediately after awakening and 30 min after waking, and "diurnal decline" (DD), calculated as the difference between levels at 30 min after waking and at bedtime. Data were analyzed using Shapiro-Wilk/Kolmogorov-Smirnov, Chi-square, unpaired t test/Mann-Whitney and paired t/Wilcoxon tests. Results: Sleep bruxism was more prevalent in children with asthma than controls (47.2% vs. 27.3%, p<0.05). More than half of the asthmatic children had intermittent severity (50.9%, p<0.001). The asthma group had higher scores of NOT-S total and interview than control group (p<0.05). Symptoms of oral dysfunctions related to (I) Sensory Function and (IV) Chewing and Swallowing were more frequent in children with asthma than controls (p<0.05). Salivary cortisol AR on weekend was significantly higher for asthma group than controls (p<0.05). In control group, salivary cortisol DD was significantly higher on weekday than weekend (p<0.05). There were no significant differences in alpha-amylase values in and between groups. Conclusions: The presence of asthma in children was associated with signs and symptoms of sleep bruxism, negative perception of sensory, chewing and swallowing functions, and higher concentrations of salivary cortisol on weekend (AU)
