- Associations between temporomandibular disorders and tinnitus : a systematic reviewPublication . Canales, Giancarlo De La Torre; Christidis, Nikolaos; Grigoriadis, Anastasios; Strandberg, Tilde; Montan, Veronica; Flores, Dyanne Medina; Al-Moraissi, Essam Ahmed; Christidis, MariaObjectives: Temporomandibular disorders (TMD) and tinnitus are highly prevalent conditions, that affects about 10–30% of the adult population and seem to co-exist. The primary objective of this systematic review was to investigate any associations between TMD and tinnitus. The secondary objective was to investigate if the associations differ between painful and non-painful TMDs. Methods: An electronic literature search in five databases was performed, from the inception of the databases until 26th of October 2022. This was to identify clinical trials with prevalence numbers of patients with TMD, with and without tinnitus and vice versa. From 1240 studies, a total number of 32 studies were included in the meta-analysis. A risk of bias analysis was made using the Methodological Evaluation of Observational Research (MORE). Results: Seventeen studies showed low risk of bias, while fifteen studies showed some risk of bias. Among patients with TMD, 57.5% also displayed tinnitus. In contrast, among patients with tinnitus, 92.9% also suffered from TMD. There was a strong association between patients with TMD that also had tinnitus, and patients with tinnitus that also had TMD (p’s < 0.001). The odds ratio for TMD-patients also having tinnitus was 1.556 (p < .05), while it for tinnitus-patients also having TMD was 2.859 (p < .05). Six studies examined the psychological status, and there was a higher degree of psychosocial distress among patients with TMD and TMD/tinnitus. Conclusions: There is a strong significant association between TMD and tinnitus, but further research is needed to unravel the nature of this association and its clinical implication.
- Influence of awake bruxism behaviors on fatigue of the masticatory muscles in healthy young adultsPublication . Barragán Nuñez, Maria Isabel; Flores, Dyanne Medina; Canales, Giancarlo De la Torre; Quevedo, Henrique Müller de; Conti, Paulo Rodrigues; Costa, Yuri Martins; Bonjardim, Leonardo RigoldiThe present cross-sectional study aimed to analyze the relationship between awake bruxism and fatigue of masticatory muscles in healthy young adults. For this purpose, 121 graduate students participated in this study. Frequency of awake bruxism was collected for 7 consecutive days by ecological momentary assessment (EMA) using an online survey (mentimeter). Muscle fatigue was tested one day after EMA assessment, which consisted of voluntarily and continuously clenching at 30% (kgf/cm2) of maximum bite force (MBF) until exhaustion. The percentage of change in MBF after the clenching task, as compared to the MBF before the clenching task was measured. The average frequency of awake bruxism was 45.5% during 7 days. Sustained clenching resulted in a significant reduction in MBF values in the total sample (p < 0.05). Nevertheless, no significant correlation was found between frequency of awake bruxism behaviors and percent of change in MBF and endurance time during the fatigue test. Therefore, it can be concluded that young healthy adults present a relatively high frequency of awake bruxism behaviors that do not seem to impact the degree of masticatory muscle fatigue.
