Mucoepidermoid carcinoma (MEC) is the epithelial salivary gland neoplasm of the oral cavity. The most common pathological type for the salivary gland tumors of the head and neck was mucoepidermoid carcinoma. In our work, we report a case of mucoepidermoid carcinoma observed in a 50-year-old man. Clinically, he presented the ulcer-budding tumor of the soft palate, movable relative to the deep plan measuring 2,5 cm. The diagnosis was based on clinical, radiological and pathological arguments. Complete surgical excision is the treatment of choice in combination with postoperative radiotherapy and chemotherapy.

This article reviews the frictional resistance of archwires based on the cross section, microscopic structure and stiffness. Bracket factors like slot width and depth and material influencing friction. Different types of ligation influencing friction. Role of saliva, biofilm and wire bracket combinations on friction. Friction in wire, bracket and ligation combination.

Background: A global review on oral health by the World Health Organization (WHO) emphasized that despite great improvements in the oral health of populations in several countries, global problems still persist. Dental caries and periodontal disease have historically been considered the most important global oral health burdens. This is particularly so among underprivileged groups in both developing and developed countries. The application of natural products for the control of oral diseases is considered as an interesting alternative to synthetic antimicrobials due to their lower negative impact, and for the effort to overcome primary or secondary resistance to the drug during therapy. Objective: To review the current evidence on the antimicrobial efficacy of plant extracts on dental caries and plaque microorganisms. Materials and Methods: A literature search was made for 6 months in PubMed, PubMed Central, MEDLINE, LILACS/BBO, Cochrane database of systematic reviews, SCIENCE DIRECT, and Google scholar databases. The results from the relevant published literatures are discussed. Summary and Conclusion: The extracts of Azadirachta Indica, Ocimum sanctum, Murraya koenigii L., Acacia nilotica, Eucalyptus camaldulensis, Hibiscus sabdariffa, Mangifera indica, Psidium guajava, Rosa indica, and Aloe barbadensis The current evidence is on individual plant extracts against bacteria involved in either caries or periodontitis. The research assessing the antimicrobial efficacy of a combination of these plant extracts against dental caries and periodontal pathogens is the need of the hour, and such research will aid in the development of a novel, innovative method that can simultaneously inhibit two of the most common dental diseases of mankind, besides slowing the development of drug resistance.

Naso-orbito-ethmoidal (NOE) fractures are considered a challenge in reconstruction, due to the anatomical structures involved, such as the medial canthal ligament and the lacrimal apparatus [1], which leads to a complex functional and aesthetic compromise. For surgical access to the area, the use of the coronal, Lynch-Howarth, glabellar “open sky”, “gull wings” and a combination of the last two are described. However, the severity of the trauma and mainly the neurological compromise of the patient will dictate the choice of the approach that allows functional and comprehensive repair of the affected region. In cases where there is no neurological compromise and it is not necessary to carry out a subcranial approach, the use of local approaches is justified, providing adequate visibility and direct access to the fractured region, allowing an adequate reduction and placement of fixing material. A clinical case of anterior frontal sinus wall fracture and NOE fracture are presented, performing the combination of the gull-wing and open-sky approach, described as butterfly wings, achieving adequate visibility and reconstruction.
