Preemptive use of intravenous ibuprofen to reduce postoperative pain after lower third molar surgery: a systematic review of randomized controlled trials

This study aimed to systematically review the literature to assess the effect of preemptive intravenous ibuprofen on pain reduction after lower third molar surgery. Nine databases (PubMed, Scopus, LILACS, SciELO, Embase, Web of Science, Cochrane, Open Gray, and Open Thesis) were used as sources of research, including "grey literature." The protocol was registered in PROSPERO. Only randomized clinical trials evaluating the effects of preemptive intravenous ibuprofen on pain during and immediately after the extraction of lower third molars were included, without restrictions of year and language. Two reviewers independently performed the study selection, data extraction, and assessment of the risk of bias. The "Joanna Briggs Institute for Randomized Controlled Trials" tool was used to assess the risk of bias. Each study was categorized according to the percentage of positive responses to the questions corresponding to the assessment instrument. The results were measured narratively/descriptively. The initial search resulted in 3,257 records, of which only three studies (n=150 participants) met the eligibility criteria and were included in the qualitative analysis. All studies were published in 2019. The risk of bias ranged from low to moderate. Two studies found significant pain reduction within 48 h after the procedure. In conclusion, the use of preemptive intravenous ibuprofen for extracting third molars reduces pain and analgesic consumption after the surgical procedure.

Tratamento cirúrgico de fratura mandibular bilateral em paciente pediátrico / Surgical treatment of bilateral mandibular fracture in a pediatric patient

Fraturas mandibulares na infância são raras e seu tratamento permanece controverso. Fatores como dentição decídua, mista ou permanente e estágio de desenvolvimento ósseo devem ser considerados para escolha do tratamento, que varia desde restrição de dieta, fixação intermaxilar, odontossíntese e até fixação interna com dispositivos de titânio ou reabsorvíveis. Esse relato descreve o tratamento cirúrgico, realizado por acesso intrabucal, de fratura bilateral de mandíbula, em uma paciente de 9 anos de idade. As fraturas foram fixadas com uma miniplaca de titânio na base mandibular e odontossíntese; e, após um ano, as placas foram removidas. A paciente apresenta boa oclusão dentária e nenhum prejuízo funcional ou estético... (AU)

During childhood, mandibular fractures are rare, and their treatment remains controversial. Factors such as primary, mixed or permanent dentition and stage of bone development should be considered when deciding on the choice of the treatment, which ranges from diet restriction, intermaxillary fixation and circumdental wiring to internal fixation with titanium or resorbable devices. This case report describes the surgical treatment, using the intraoral approach, of a bilateral mandibular fracture, in a nine-year-old patient. The fractures were fixed with a titanium miniplate on the mandibular base and circumdental wiring, the plate being removed after one year. The patient shows a good dental occlusion and no aesthetic or functional injury... (AU)

Bloqueio anestésico do nervo alveolar inferior: Técnica de Jorgensen & Hayden Modificada / Anesthesic block of the inferior alveolar nerve. Technique of Jorgensen & Hayden Modified

Na prática odontológica é comum encontrar queixas relacionadas com as técnicas de bloqueio anestésico do nervo alveolar inferior (N.A.I.). As taxas de sucesso na realização das técnicas anestésicas convencionais variam entre 80 e 85%, mesmo quando aplicadas adequadamente. A proposta desse trabalho é apresentar uma contribuição à técnica anestésica convencional de Jorgensen e Hayden, enriquecendo-a de detalhes anatômicos importantes, visando a aumentar o índice de sucesso na obtenção de anestesia dos nervos alveolar inferior e lingual
