Impact event and orofacial pain amid the COVID-19 pandemic in Brazil: a cross-sectional epidemiological study

Objectives: This study aims to assess the impact of social isolation, due to the Covid-19 pandemic, on mental health, Temporomandibular Disorder (TMD) and orofacial pain in men and women. Methodology: Individuals living in Brazil answered an online questionnaire on their sociodemographic and behavioral aspects, emotional scale (DASS-21), Impact of Event Scale, and Pain Screener in Temporomandibular Disorders (TMD-Pain Screener) during June 2020. Descriptive statistical analyses and logistic and linear regressions were applied (5% significance). Results: Overall, 2301 individuals were included, 89.1% practiced social isolation, 72.6% were employed/studying, at least 15% presented severe or extremely severe levels of emotional distress and presence of powerful (34.1%) and severe impact event (15%). During the outbreak, 53.2% perceived feeling worse and 31.8% reported that orofacial pain started or worsened after the pandemic outbreak. Gender was associated with “social class” (P=0.036), “pain/stiffness in the jaw on awakening” (P=0.037), “change of pain during jaw habits” (P=0.034) and “perception of change in the situations mentioned in the TMD-Pain Screener” (P=0.020), “depression” (P=0.012), “anxiety” (P=0.006) and “impact of the event” (P=8.3E-11). Social isolation had a lesser chance to change the routine, to be practiced by the unemployed/not studying, and to be practiced by men (all with P<0.001). Associations were found between social class and all subscales of the DASS-21 and IES, all with P<0.001. Conclusions: The practice of social isolation has social determinants. High levels of psychological and event impacts were detected. The presence of orofacial pain seemed to increase during the health crisis, and there were gender differences in the response to the COVID-19 pandemic

Masticatory efficiency, bite force and electrical activity of the masseter and temporalis muscles in bodybuilders

This study aimed to compare the masticatory efficiency, the maximum voluntary occlusal bite force (MVOBF) and the electrical activity (EMG) of masticatory muscles of practitioners of upper limb bodybuilding before and after physical activity. Twenty he

Relationship between self-reported pain, pain threshold, pain catastrophization and quality of life in patients with TMD

The aim of this study was to verify if there is a relationship between self-reported pain, PPT (pressure pain threshold) of the masseter, temporal and sternocleidomastoid muscles, pain catastrophizing and quality of life in patients with TMD (temporomand

Relationship of excessive daytime sleepiness with bruxism, depression, anxiety, stress, and sex in odontology students: a cross sectional study

To verify if there is a correlation of excessive daytime sleepiness (EDS) with bruxism, depression, anxiety, stress, and sex in odontology students. Four hundred dental students were selected. Students included in the study were those that were healthy

Aleitamento materno como fator de proteção contra a instalação de hábitos bucais deletérios

Objetivo: avaliar a possível associação entre as variáveis sociodemográficas, desmame precoce e o desenvolvimento e manutenção dos hábitos bucais deletérios em crianças de três a cinco anos de idade das creches públicas de Vitória/ES.Método: trata-se de um estudo longitudinal, retrospectivo, com uma amostra final de 903 escolares, aleatorizada e representativa das 9.829 crianças matriculadas. Para a comparação entre as variáveis predictoras e hábitos foi utilizado o teste exato de Fisher e a força da associação medida pelo Odds Ratio.Resultados: 12,4% das crianças apresentaram hábito de sucção digital e 37,7%, o de chupeta. Não foi verificada associação estatisticamente significante do hábito de sucção digital com desmame precoce. As crianças do sexo feminino (p=0,045) demonstraram 20% mais chance de adquirir e permanecer com o hábito de chupeta, e as que tiveram o desmame precoce apresentaram aproximadamente quatro vezes mais a chance de desenvolver o hábito de chupetas (p= 0.000).Conclusão: associação entre hábito de chupeta e desmame precoce foi verificada. O desmame precoce pode ser considerado fator de risco para a permanência do hábito de chupeta

Treatment of Masticatory Muscle Pain with Acupuncture: Is It Necessary to Associate with Occlusal Splints?

Background : Temporomandibular disorders (TMDs) are treated by different modalities including splints, physiotherapy, and acupuncture. Although all of these offer evidencebased benefits to the patients, avoiding overtreatment is of paramount importance. Objectives: To assess the effectiveness of muscle pain treatment with acupuncture combined with or without occlusal splints. Methods : Recruited patients were allocated to G1 (acupuncture) and G2 (acupuncture and occlusal splint) groups and treated in four consecutive weekly sessions (P1, P2, P3, and P4). The reported pain (RP) and the pressure pain threshold (PPT) of the masseter and temporalis muscles were assessed before and after each session. Results : RP decreased after each session in G1, except at P4. In G2, the RP decreased only after the first session, and the PPT did not vary. Conclusion : The assessed treatments did not influence the PPT levels of the masseter and anterior temporalis muscles in patients with temporomandibular disorders. Our findings suggest that occlusal splints may not be mandatory along with the acupuncture treatment
