Posterior mandible region is considered a highly predicable place for primary stability during dental implant placement. Although, this region can present a significant decrease in bone density, which can lead to implant dislocation during insertion. The present case reports an unusual dislocation of dental implant in a 59 old healthy patient's mandible and a secure solution for this kind of complication. During the drilling, bone quality type IV was observed. In sequence, implant was abruptly inserted in the perforation site and dropped into the bone marrow. Panoramic radiograph showed the implant inside bone marrow, close to mandibular base. The implant was removed through the surgical site. The screw of the implant prosthesis transfer was used to reach the displaced implant. A second implant with the same dimensions as the first one, differing by the external hexagon, was inserted into the same implant site. Therefore, the authors strongly recommend the use of the presented technique prior to osteotomy on mandibular body, reserving the second in the impossibility of reaching the internal connection of the displaced implant.
O abuso de drogas, lícitas ou ilícitas, é um dos principais problemas sociais e de saúde pública do mundo, sendo assim o contato do cirurgião dentista com pacientes dependentes dessas substâncias é inevitável. Estudos sugerem que o uso de drogas aumenta as manifestações orais, como alterações do fluxo salivar, desgaste dental, cárie, doença periodontal, xerostomia e dor. Por isso, o profissional deve estar preparado para atender esses pacientes, e ter conhecimento sobre as limitações e possíveis interações, principalmente em tratamentos invasivos, seja em ambiente hospitalar com o paciente sedado ou no consultório com anestésicos locais. O objetivo deste trabalho é relatar um caso de monitoramento da pressão arterial, saturação de oxigênio e frequência cardíaca, durante um procedimento com múltiplas exodontias em uma paciente dependente química. Apesar da paciente se manter estável, foi constatado aumento da pressão diastólica no pós-operatório, podendo estar relacionado com a vasoconstrição causada pelo uso da maconha e crack, e a ação da epinefrina do anestésico. Esse aumento se relaciona com alterações no sistema simpático e parassimpático, por isso a importância de se conhecer as substâncias empregadas no procedimento e em medicamentos receitados. Conclui-se que é preciso aprimorar o conhecimento das alterações fisiológicas, químicas e neurológicas que envolvem esses pacientes, para um tratamento odontológico seguro, e quando necessário em conjunto com uma equipe multiprofissional, saber encaminhar o paciente e identificar problemas de saúde não somente bucais.
This study aimed to perform a systematic review and meta-analysis to evaluate the preemptive action of the combination of corticosteroids and non-steroidal anti-inflammatory drugs (NSAIDs) or both drugs singly after third molars surgery. It was performed a search on the PubMed/MEDLINE, Scopus, and Cochrane databases, according to the PRISMA criteria, with no time restrictions up to March 2020. The postoperative pain was evaluated, qualitatively, through the visual analogue scale (VAS) and the number of rescue analgesics (NRA). The edema and trismus were evaluated in a qualitative way through linear measures. Besides that, a meta-analysis of the post-operative pain (VAS) was performed. It was found 103 articles, which four articles were selected according to the inclusion and exclusion criteria. A total of 208 patients was evaluated and the combination of corticosteroids and NSAIDs showed great behavior in the preemptive action after third molars surgery for all the parameters evaluated when compared to both drugs singly. Meta-analysis about the VAS showed that the combination of drugs reduced significantly the postoperative pain when compared to the NSAIDs singly (P<0.05). It was concluded that the combination of NSAIDs and corticosteroids improved postoperative pain, edema, and trismus after third molars surgery.
O herpes-zóster é uma infecção viral causada pela reativação do vírus da varicela-zóster, que acomete geralmente a população idosa. O vírus da varicela, quando em estado dormente, se localiza nos gânglios trigeminais e quando reativado pode causar lesões no rosto e vesículas intra bucais. Esta doença pode afetar com maior prevalência pacientes imunossuprimidos e caracteriza-se por erupções maculopapulares distribuídas na região do nervo afetado, causando dores intensas, tremores e até parestesia. O diagnóstico do herpes zoster geralmente é estabelecido por meio do quadro clínico apresentado pelo paciente e o tratamento é voltado aos sintomas e à causa, optando pelo uso de medicações antivirais sistêmicas e tópicas. Este artigo relata o caso de uma paciente, do sexo feminino, leucoderma, sem problemas de saúde e tratamentos imunossupressores prévios, de 56 anos de idade, que deu entrada ao pronto socorro, tendo com queixa principal a dor extra oral em hemiface direita, com evolução rápida de três dias após exodontia.
The Peripheral Ossifying Fibroma is a benign tumor that develops from a hyperplastic tissue reaction, usually related to traumatic stimulus that are responsible for triggering inflammatory reactions of the connective tissue. Histologically, it is a nodular mass characterized by a dense connective tissue, surrounded by stratified squamous epithelium. Surgical removal in these cases is indicated, and for reconstruction of soft tissue in the region, some periodontal surgical techniques are recommended, such as free gingival grafting. Thus, the present study aims to report a clinical case submitted to the free gingival graft technique for tissue reconstruction after the surgical removal of a fibroma. A total excision of the lesion was performed, later sent to a histopathological report where it was diagnosed as Peripheral Ossifying Fibroma, after the removal of the lesion the region was left with the periosteum exposed and then the free gingival graft was performed to cover the region and promote keratinized gum augmentation. This technique proved to be efficient for reconstruction of soft tissue in the region after surgical removal of the Peripheral Ossifying Fibroma, returning aesthetics, function and periodontal health.
The membranes used in bone reconstructions have been the object of investigation in the field of tissue engineering, seeking to improve their mechanical strength and add other properties, mainly the osteopromotive. This study aimed to evaluate the functionalization of collagen membranes, with atomic layer deposition of TiO2 on the bone repair of critical defects in rat calvaria and subcutaneous biocompatibility. A total of 39 male rats were randomized into four groups: blood clot (BC), collagen membrane (COL), COL 150—150 cycles of titania, and COL 600—600 cycles of titania. The defects were created in each calvaria (5 mm in diameter) and covered according to each group; the animals were euthanized at 7, 14, and 28 days. The collected samples were assessed by histometric (newly bone formed, soft tissue area, membrane area, and residual linear defect) and histologic (inflammatory cells and blood cells count) analysis. All data were subjected to statistical analysis (p < 0.05). The COL150 group showed statistically significant differences compared to the other groups, mainly in the analysis of residual linear defects (1.5 ± 0.5 × 106 pixels/µm2 for COL 150, and around 1 ± 0.5 × 106 pixels/µm2 for the other groups) and newly formed bone (1500 ± 1200 pixels/µm for COL 150, and around 4000 pixels/µm for the others) (p < 0.05), demonstrating a better biological behavior in the chronology of defects repair. It is concluded that the collagen membrane functionalized by TiO2 over 150 cycles showed better bioactive potential in treating critical size defects in the rats’ calvaria.
Malignant oral neoplasms have great relevance because they represent one of the main causes of death in the world. Squamous cell carcinoma is its most frequent form, but reports in the retromolar region are rare when compared to other oral sites. The objective of this work is to demonstrate the diagnosis and conduct in the case of a patient participating in the Oral Injury extension project (LeBu) at the State University of Maringá - PR/BR. Male patient, 67 years old, a heavy smoker for about 50 years, alcoholic, attended the university with an ulcer in the right lower retromolar region of brownish-white color, with approximately 3 to 4 mm, irregular shape, and rough surface. A biopsy was performed in the lesion region, collecting a fragment of approximately 2 mm, which was referred for histopathological examination, resulting in a diagnosis of moderately differentiated, invasive squamous cell carcinoma. The patient was referred for medical oncological, surgical, and chemotherapy treatment, remaining under dental monitoring throughout the treatment and later with scheduled returns. After 4 years of follow-up, the patient is in good general physical condition, with no signs of recurrence, orally rehabilitated, even quitting the smoking habit. Thus, it is concluded that the diagnosis and treatment of head and neck neoplasms lacks a multidisciplinary view, being the dental surgeon of great importance both for the diagnosis of these injuries, as well as in the prevention and treatment of injuries that may arise from or after the treatment.
