The prevalence of impaction of the permanent canine on the cleft side (PCCS) ranges from 12-35% after alveolar bone grafting (ABG). PCCSs usually develop above other permanent teeth in the alveolar process, gradually becoming vertical until they reach the occlusal plane. The type of cleft, hypodontia of lateral incisor on the cleft side, slower PCCS root development, and genetic factors are predictors of impaction and/or its ectopic eruption. Objective: To compare the behavior of PCCS in individuals with complete unilateral cleft lip and palate (UCLP) subjected to secondary alveolar grafting (SAG) with different materials. Methodology: This retrospective longitudinal study analyzed 120 individuals undergoing SAG with iliac crest bone, rhBMP-2, and mandibular symphysis. The individuals were selected at a single center and equally divided into three groups. Panoramic radiographs were analyzed by the Dolphin Imaging 11.95 software to measure PCCS angulation and PCCS height from the occlusal plane at two different timepoints. Results: No statistical significance was found between grafting materials (P=0.416). At T1, the PCCS height from the occlusal plane was greater for rhBMP-2 and mandibular symphysis compared to iliac crest bone. The lateral incisor on the cleft side was not related to success or lack of eruption of PCCS (P=0.870). Conclusion: Impaction rates of PCCS were similar for the materials studied. Absence of the lateral incisor on the cleft side did not prevent spontaneous eruption of PCCSs.

The aim of this study was to evaluate the outcome of cleft-permanent canine (CPC) impaction in individuals with complete unilateral cleft lip and palate (CUCLP) submitted to secondary alveolar grafting (SAG) with different materials. Study Design: Retrospective longitudinal study analyzed 120 individuals undergoing AG with iliac crest, rhBMP-2 and mandibular symphysis. The individuals were selected at a single center and divided equally into three groups. Panoramic radiographs were analyzed by Dolphin Imaging 11.95 to measure CPC angulation and distance from occlusal plane of the CPC at two different timepoints. Interphase and intergroup comparisons were performed using analysis of variance (p<0,05). Results: No statistical significance was found between grafting materials (P=0.416). At T1, the distance from occlusal plane was greater for rhBMP-2 and mandibular symphysis. Lateral incisor was not related to success or failure of CPC eruption (P=0.870). Surgeon shown statistical significance for CPC eruption (P=0.045). Conclusion: CPC eruption was similar for materials studied. Surgeon influenced the CPC eruption that did not depend on the lateral incisor in cleft side to erupt spontaneously.

A metástase é consequência de uma cascata biológica complexa, que se inicia com o desprendimento de células tumorais de um sítio primário e, por via hematogênica ou linfática, se disseminam para outras regiões, onde passam a residir e se multiplicar, formando os chamados “implantes secundários” nesses novos locais. As lesões metastáticas na região bucomaxilofacial representam cerca de 1% de todos os tumores malignos desta região, sendo a cavidade oral o principal sítio primário dessas neoplasias. O câncer da região bucomaxilofacial apresenta altas taxas de morbimortalidade. Assim, é necessário que o médico e/ou cirurgião dentista leve em consideração as metástases para essa região, pois, apesar de ser um caso raro, indicam que a neoplasia já se encontra em estágio avançado. Diante do exposto, este estudo teve como objetivo realizar uma revisão sistemática da literatura sobre os locais do tumor primário que possuem metástase para a região bucomaxilofacial, bem como o local da metástase, gênero mais acometido e o tipo histológico mais comum. Para a construção deste artigo foi feito um levantamento bibliográfico nas bases de dados SciVerse Scopus, Scientific Eletronic Library Online (Scielo), U.S. National Library of Medicine (PUBMED) e ScienceDirect, com auxílio do Mendeley. Os artigos foram coletados no período de abril a agosto de 2021 e contemplados entre os anos de 2010 a 2021. A partir de uma revisão sistemática da literatura, observou-se 282 casos de metástase para a região bucomaxilofacial. Os sítios primários que mais metastatizaram foram pulmão, rim, mama e fígado. O gênero mais acometido foi o masculino e a mandíbula foi o local mais acometido, seguido por gengiva e língua. O tipo histológico mais comum foi o carcinoma.

The present project, a research related to maxillofacial surgery and traumatology, has the purpose of studying the prevalence of facial fractures in Brazil. It is not today that the fractures of the face affect the human being. From the earliest times, man had already had an interest in the subject. In contemporary times, it is known that the facial fracture is due to the discontinuity of the bone tissue of some component of the viscerocranium when a certain physicalmechanical force is exerted against such a bone element. Facial bones are engineered to provide protection and contouring of the face, as well as collaborate in the respiratory, phonetic and digestive systems. Therefore, there is some inequality in the prevalence of maxillofacial fractures, in which the nasal bones are the most affected, followed by the zygomatic bones, which are characterized as the most prominent. However, this may vary according to the etiological agent. According to a survey done in the Bauru region (SP), 1996, as an example, zygomatic fracture (29.2%) and orbit (44%) are predominantly due to aggressions, and the maxilla (35.5% %) of automobile accidents. A survey conducted in the northeast of the country in 2016 showed that the traffic accident prevailed with 52% while the violence showed 34%. Another study carried out in the south of Brazil presents the same etiology pattern for automobile accidents, with a percentage of 27.9%, but in relation to interpersonal violence did not present specific data. The humbler regions are predominantly the most affected by this etiology, when compared to the noblest regions of the city. Among the etiologies mentioned in the screen project, those that predominate are those derived from motor vehicle traffic and
