As third molar surgery is the most commonly procedure performed in Dentistry and has been accompanied by serious postoperative disorders such as pain, edema and trismus, the study aimed to evaluate if ultrasound device would be able to reduce such postoperative features. The aim of this study was to assess the effects of soft tissue flap elevation, osteotomy and odontosection using piezosurgery versus conventional technique in mandibular third molar extractions. Twenty patients with impacted mandibular third molars underwent tooth extractions using two different methods. Ten patients were included in the Piezo Flap Group (PFG - the flap was elevated using piezosurgery) and ten patients were part of the Piezo Ostectomy Group (POG - osteotomy and odontosection were carried out with ultrasound tips). The contralateral tooth was included in the Control Group (CG - conventional technique). The patients were evaluated at postoperative periods of 1, 3, 7 and 14-days. The measured parameters were duration of surgery, pain, trismus and swelling. The mean duration of surgery for the PFG was 17.21 minutes (CG 10.07 minutes) and POG was 40.09 minutes (CG 15.97 minutes). There was no statistically significant difference in pain and trismus for any of the postoperative periods evaluated in PFG and POG (p>0.05). There was a statistically significant difference in swelling between the PFG and POG, presenting less swelling at the 3-day postoperative period (p=0.038; p0.05). Piezosurgery for tissue elevation of the surgical flap, osteotomy and dental sectioning in mandibular third molar extraction surgery promoted less edema in the early postoperative stages in mandibular third molar extractions despite the longer surgical duration.

O objetivo desta pesquisa foi analisar o conhecimento, opinião, acompanhamento e a execução do cirurgião-dentista na Odontologia Hospitalar. Foram aplicados 500 questionários a cirurgiões-dentistas na cidade de Araçatuba do estado de São Paulo. Os resultados demonstraram que 49% dos profissionais nunca tiveram a experiência no âmbito hospitalar e 64% afirmaram que este conteúdo é carente como parte integrante do currículo de graduação. Outro resultado foi de que 46% dos entrevistados não têm interesse ou não acham necessário atuar dentro do hospital e 24% acreditam que esse atendimento seja feito somente por especialistas. Pode-se sugerir que há carência de conhecimento sobre Odontologia Hospitalar, assim o cirurgião-dentista deve ser instruído desde a sua formação acadêmica para a inserção na equipe hospitalar.

Mucoceles are benign pseudocystic lesions, whose main etiological factors are trauma and ductal obstruction, with the rupture of a duct in the salivary gland and leakage of mucin into the adjacent soft tissues. They are characterized by being asymptomatic and often present spontaneous rupture. Histologically, they are made up of a cystic wall devoid of epithelium, outlined by granulation tissue and inflammatory cells. Mucoceles usually present as dome-shaped mucous swellings, which can vary in size from 1 to 2 mm to a few centimeters, characterized as a floating lesion, although some may be firm on palpation. The evolution time reported for this lesion varies from a few days to several years, and the most common site of involvement for this phenomenon is the lower lip. Some mucoceles are self-limiting, with spontaneous rupture and scarring, however, many of these lesions are chronic in nature, and local surgical excision may be necessary. The aim of this study was report a clinical case of mucocele on the lower lip. The surgical removal of the mucocele proved to be an effective and safe technique in the case in question, enabling the histopathological diagnosis of the lesion.
