“…With respect to self-perceptions regarding bruxism, female adolescents tended to report the problem more often. 1 The association between gastroesophageal reflux and bruxism was in agreement with findings reported in previous studies 10,20 but differed from data described for individuals with cerebral palsy. 7 An increase in the rhythmic activity of the masticatory muscles, salivary flow and swallowing has been demonstrated through experimental acidification in healthy adults.…”

The aim of the present study was to investigate factors associated with bruxism in children aged from 1 to 13 years with developmental disabilities. A total of 389 dental records were examined. The bruxism analyzed was determined based on parental reports. The following variables were also analyzed: gender, age, International Code of Diseases (ICD), mouth breathing, history of gastroesophageal reflux, use of psychotropic drugs, gingival status, reports of xerostomia, hyperkinesis, pacifier use, thumb sucking and involuntary movements. For the purposes of analysis, the individuals were categorized as being with and without bruxism. Variables with a p-value < 0.25 in the bivariate analysis were incorporated into the logistic regression models. Females had a 0.44-fold (95%CI: 0.25 to 0.78) greater chance of exhibiting bruxism than males. Individuals with gastroesophageal reflux had a 2.28-fold (95%CI: 1.03 to 5.02) greater chance of exhibiting bruxism. Individuals with reported involuntary movements had a 2.24-fold (95%CI: 1.19 to 4.24) greater chance of exhibiting bruxism than those without such movements. Exhibiting involuntary movements, the male gender and gastroesophageal reflux are factors associated with bruxism in children with developmental disabilities.

“…As NNS is under the control of brainstem premotor circuitry during sleep (Bonis et al, 2013;Little et al, 1997;López-Alonso et al, 2006;Miyawaki et al, 2003;Vandenplas et al, 1991), the present study does not provide additional clues as to the mechanisms (peripheral vs. central) responsible for the alteration of brainstem swallowing center function in the presence of laryngitis. Finally, the decrease in NNS burst frequency in AS raises the question of a similar impediment of nutritive swallowing bursts during bottle-feeding (Bernier et al, 2012), which may in turn decrease swallowing efficiency and promote lung aspiration.…”

Reflux laryngitis in infants may be involved not only in laryngeal disorders, but also in disorders of cardiorespiratory control through its impact on laryngeal function. Our objective was to study the effect of reflux laryngitis on non-nutritive swallowing (NNS) and NNS-breathing coordination. Two groups of six newborn lambs, randomized into laryngitis and control groups, were surgically instrumented for recording states of alertness, swallowing and cardiorespiratory variables without sedation. A mild to moderate reflux laryngitis was induced in lambs from the experimental group. A significant decrease in the number of NNS bursts and apneas was observed in the laryngitis group in active sleep (p = 0.03).In addition, lower heart and respiratory rates, as well as prolonged apnea duration (p < 0.0001) were observed. No physiologically significant alterations in NNS-breathing coordination were observed in the laryngitis group. We conclude that a mild to moderate reflux laryngitis alters NNS burst frequency and autonomous control of cardiac activity and respiration in lambs.

Association Between Nocturnal Bruxism and Gastroesophageal Reflux

Abstract: Nocturnal bruxism may be secondary to nocturnal gastroesophageal reflux, occurring via sleep arousal and often together with swallowing. The physiologic link between bruxism and the increase in salivation needs to be investigated.
