Objective: This study aims to compare data relating to gender, age, etiology, fractured areas, procedures performed, follow-up and purpose from September 2013 to July 2015. This retrospective study included patients whose medical records were complete and who presented face fractures due to gunshot wounds. Results: A total of 1289 patients diagnosed with fractures in the head and neck region were evaluated, of which only 13 patients had facial fractures caused by firearms. Stabilization of facial fractures with rigid internal fixation should be performed as soon as possible to avoid sequelae to the patient, which was conduc- ted in 8 patients. Conclusions: The study found that male and young patients are the most affected by fire injuries to the face due to the high rate of violence, cultural and socioeconomic differences in the city of São Paulo. Fracture stabilization must be performed as soon as possible to avoid future sequelae. Therefore, the study found that the care of facial trauma by firearm does not have a strict protocol; it depends on the extent and severity of each case.

Objective: To report a case of pleomorphic adenoma that was surgically removed and to describe the surgical technique available to remove this lesion. Case Report: A male patient, caucasian, 46 years old, with a 4-year history of pleomorphic adenoma. He mentioned that he went to other services for treatment, but without success. He came at our service for treatment with tumoral excision. Local anesthesia was performed with mepivacaine with a vasoconstrictor and tumoral excision was performed with the overlying mucosa and the periosteal region to avoid recurrence. The patient has been under postoperative follow-up for two years without recurrence. Conclusion: Pleomorphic adenoma is a benign tumor and presents as a submucosal mass of slow growth. The ideal treatment for the Pleomorphic Adenoma tumor is the total excision of the lesion with the removal of the mucosa covering the region to avoid recurrence.

Objective: Report a case of pyogenic granuloma with two years of evolution, three previous removals with external oral and maxillofacial surgeons, and new recurrences. Case Report: A 25-year-old male patient with a history of a pyogenic granuloma with two years of evolution had three previous removals with external maxillofacial and had relapses. The treatment indicated after these relapses were the extraction of the involved teeth and the lesion, performing the closure with a buccal fat pad flap. The lesion underwent metaplasia, transforming into mucosa.Conclusion: This case emphasizes keeping the buccal fat pad as a possible future resource for regional grafting.

Objetivo: O objetivo desta revisão bibliográfica foi descrever estudos que buscaram analisar a efetividade da tomografia computadorizada cone beam (TCFC) na análise da densidade mineral óssea (DMO) da região maxilo-mandibular. Foram incluídos nesta revisão artigos referentes ao uso da TCFC na análise da DMO da região maxilo-mandibular de 2009 até 2020,  publicados nas base de dados: PUBMED, EMBASE e Scopus.Resultados: Foram selecionados 17 artigos que investigaram o uso da TCFC no estudo da DMO maxilo-mandibular. Muitos pesquisadores utilizaram-se da micro-tomografia, tomografia computadorizada multislice e análise histomorfométrica para realizar comparações com a TCFC.Conclusões:  As evidências bibliográficas sugerem que a TCFC, tanto através dos seus valores de escala de cinza quanto pelos seus parâmetros 3D estruturais, se apresenta como um método de relevância clínica, confiável e fácil, de análise proporcional da densidade óssea da região maxilomandibular.
