Temporomandibular joint disorders in skeletal class II patients referred to orthognathic surgery: A cross-sectional study.

OBJECTIVES: The aim of this study was to assess the prevalence of Temporomandibular Disorders (TMD) in subjects with skeletal class II dentofacial deformity referred for orthognathic surgery, as well as to elucidate its association with sociodemographic and psychosocial features. METHODS: This was a cross-sectional study using the Research Diagnostic Criteria for Temporomandibular Disorders. The sample comprised class II skeletal patients referred to an Oral and Maxillofacial Surgery center in the Brazilian Northeast. RESULTS: Seventy-three subjects were enrolled and completed the data collection, which consisted of a physical examination according to Axis I of the Research Diagnostic Criteria for Temporomandibular Disorders and facial analysis. Women represented 82.2% of the sample. Among the assessed subjects, 68.5% were already undergoing orthodontic treatment, and the mean overjet of patients was 6.97 mm. The prevalence of TMD in this sample was 46.6%, with muscular disorders being the most common. Patients with an anteroposterior discrepancy greater than 7 mm showed a higher occurrence of TMD (p = 0.017). CONCLUSION: This study demonstrated a high prevalence of TMD in skeletal class II patients referred for orthognathic surgery, especially in those with a pronounced overjet, being Group I (muscular disorders) and Group III (degenerative disorders) the most prevalent.

Essential Oils in Experimental Models of Neuropsychiatric Disorders: A Systematic Review.

BACKGROUND: Neural cells undergo functional or sensory loss due to neurological disorders. In addition to environmental or genetic factors, oxidative stress is a major contributor to neurodegeneration. In this context, there has been a growing interest in investigating the effects of EOs (EOs) in recent years, especially in the treatment of neuropathologies. The chemical and biological effects of EOs have led to important treatment tools for the management of various neurological disorders. OBJECTIVE: In the present study we performed a systematic review that sought to comprehend the neuroprotective effects of different EOs. METHOD: This work is a systematic review where an electronic search was performed on PubMed, ScienceDirect, Cochrane Library and SciELO (Scientific Electronic Library Online) databases, covering the last 10 years, using "Essential oil" and "Neuroprotective effect" as reference terms. RESULTS: A total of 9 articles were identified, in which the efficacy of EOs was described in experimental models of anxiety, dementia, oxidative stress, cerebral ischemia, Alzheimer's disease, and oxidative toxicity. CONCLUSION: EOs from different species of medicinal plants have shown positive responses in neurological disorders such as anxiety, dementia, oxidative stress, cerebral ischemia, and oxidative toxicity. Thus, EOs emerges with the potential to be used as alternative agents in the treatment of neurological disorders.

[Preference and factors associated with the type of delivery among new mothers in a public maternity hospital]. / Preferência e fatores associados ao tipo de parto entre puérperas de uma maternidade pública.

OBJECTIVE: To identify reproductive and socioeconomic factors that influence the preference for a method of childbirth. METHOD: Data were collected using semi-structured interviews with 233 women in postpartum care. Data were analyzed using association tests, namely the Chi-square test and multiple logistic regression. RESULTS: The preference for vaginal childbirth was cited by 58% of women. The main reasons for this preference were quick postpartum recovery, a negative experience in Caesarean childbirth and fulfilment through motherhood. Analysis of the logistic models of preference for vaginal delivery according to the independent variables revealed a greater occurrence in women who had previous experience of this type of delivery (PR: 1.91; CI: 1.15-3.17) and had received prior guidance (PR: 1.76; CI: 1.06-2.90). CONCLUSION: Findings highlight the need to transform the model of care provided during pregnancy and childbirth.
