Tumor necrosis factor alpha (TNF-α) blockage reduces acute inflammation and delayed wound healing in oral ulcer of rats.

Oral traumatic ulcers (OTU) are common in dental routine, and the control of proinflammatory cytokines, such as the tumor necrosis factor-alpha (TNF-α), may interfere with OTU repair. Our aim was to evaluate the role of TNF-α in the healing process of OTU in rats. Wistar male rats were divided into six groups: a control-group (treated with 0.

Distance education in dentistry in Brazil: a critical STROBE-based analysis.

The COVID-19 pandemic has forced dentistry schools (DSs) to adapt their teaching techniques to digital platforms. Therefore, we aimed to evaluate distance classes in the Brazilian DS curriculum. After an online search of higher education institutions (HEIs) with DS on the e-Ministry of Education (MEC) platform, we included institutions with at least one graduated class to extract the age/localization of the DS, funding, number of authorized seats, MEC-grade, ENADE-score, and workload.

Association of anxiety, depression, and stress with burning mouth syndrome: a case-control study.

Burning mouth syndrome (BMS) is a painful disorder characterized by severe burning in the oral cavity in the absence of clinical signs. In this case-control study, 60 patients were allocated to 3 groups: patients with BMS, patients with benign changes in the oral cavity (anxiety [positive] control group), or healthy patients (negative control group). A visual analog scale (VAS), Beck Anxiety and Depression inventories, Lipp Stress Symptoms Inventory, Xerostomia Inventory-Dutch Version, and a BMS questionnaire were used.

Photobiomodulation Therapy Reduces the Inflammatory Process without Inhibiting Bone Deposition in Rats in an Extraction Model.

We evaluated the influence of photobiomodulation therapy (PBMT) application during bone healing postexodontia in rats. We divided 84 male Wistar rats into a control group (CG), which received placebo treatment without PBMT, and a test group (TG), which was treated with PBMT. After exodontia, the animals were subjected to PBMT (TG) with an AsGaAI diode laser at 810 nm, 100 mW, 2 J, and 70 J/cm or placebo treatment (CG) every 72 h.
