KOSTNER URIBE, S; BRUNET ECHAVARRIA, J  and  TAPIA VARGAS, A. Sleep disorders associated with sleep bruxism in children between 3 and 6 years old attended at the Dental Clinic of the University Mayor of Santiago, Chile. Av Odontoestomatol [online]. 2019, vol.35, n.2, pp.83-91.  Epub May 18, 2020. ISSN 2340-3152.  https://dx.doi.org/10.4321/s0213-12852019000200005.

Bruxism is defined as a repetitive activity of the chewing muscles characterized by grinding and clenching the teeth, and / or tension or displacement of the jaw 20 . This one has two circadian manifestations: It can occur during sleep (BS) or during wakefulness 12 . In children, the most reliable clinical method to diagnose is still based on the report of grinding by their parents or caregivers; however, most children sleep away from parents 10 . There is a diagnostic difficulty in establishing the loss of tooth structure due to bruxism in children, since it must be differentiated from the physiological wear that occurs in the temporary teeth. There are some sleep disorders, cataloged by the International Classification of Sleep Disorders 41 that have been associated with BS 6 , 17 ,31. The objective of this study was to establish whether there is an association between BS and sleep disorders in preschoolers. 100 children in the Odontological Clinic of the Universidad Mayor of Santiago, Chile, between 3 and 6 years old were evaluated, through clinical evaluation and anamnesis consulted to parents or guardians to determine the presence of BS, in addition to the survey “Scale of Sleep Disorder in Childhood, for preschoolers. “ The study showed a prevalence of BS of 47%, with no difference between boys and girls, and an association of some of the sleep disorders with BS (Parasomnias, Respiratory Problems, Hyperhidrosis and Not Restful Sleep). As a conclusion, there is an association between sleep disorders and BS.
