Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2018, Vol 17, Issue 1
Abstract
Introduction: Intense forces during sleep bruxing behavior may negatively affect both adjacent and distant anatomic structures including the cervical area. Aim: Evaluate the frequency of morningawakening with cervical pain in different bruxing behavior subgroups ,and compare severity of bruxing behavior in those bruxers with or without a report of morning awakening with cervical pain. Material and Methods: History of signs and symptoms, self-report and clinical examination were used to evaluate282 mixed, 103 sleep, 61 diurnal bruxers with temporomandibular disorders, 28 bruxers without TMDs and 32 non bruxers without temporomandibular disorders. A questionnaire as part of a comprehensive method to assess diurnal, mixed and sleep bruxers was also used to determine the presence of morning awakening with cervical pain. Kruskal-Wallis statistics was used to evaluate age differences and scores in bruxing behavior when subgroups with and without cervical pain on awakening in the morning were compared. Fisher´s exact test was used to evaluate genre differences in five groups. Results: There were no age differences when all subgroups were compared (Kruskal-Wallis´statistics p=0.70). Females predominated in the experimental and control subgroups. However, statistical significant differences were observed only when the mixed and diurnal subgroups (p<0.001), mixed bruxers andbruxers without TMDs (p<0.0001); mixedbruxers and non bruxers/non TMDs (p<0.0001), Sleep bruxers and diurnal bruxers (p<0.004), Sleep bruxers and bruxers without Temporomandibular disorders (p<0.0001), Sleepbruxers and non bruxers / non Temporomandibular disorders (p<0.0001), were compared. Regarding the frequencies of morning awakening with cervical pain, higher frequencies were observed only when the subgroups mixed and diurnal bruxers (p<0.0001); mixed bruxers and bruxers without temporomandibulardisordes (p<0.0001); mixed bruxers and non bruxersnon temporomandibular disorders (p<0.01); Sleep bruxersand diurnal bruxers (p<0.0001); Sleep bruxersand bruxers without temporomandibular disorders (p<0.001) and diurnal bruxers and non bruxers and non temporomandibular disorders, were contrasted (p=0.05). Conclusions: Morning awakening with headache is found more frequently in mixed and sleep bruxers with temporomandibular disorders. Future studies should evaluate the mechanisms associated with morning awakening with cervical pain in mixed and sleep bruxers.
