The aim of this study is to describe a case of dentigerous cysts of a young patient successfully treated as well as clinical and radiographic follow-up. A 10-year-old female patient was referred to the Buccomaxillofacial Surgery and Traumatology Service of the Regional University Hospital of Campos Gerais. The patient's panoramic radiograph revealed a well-defined radiolucent unilocular area associated to the crown of the second permanent right lower molar, which was impacted. In addition, the permanent upper canines were enclosed, suggesting a dentigerous cyst. A conservative treatment was determined, through marsupialization of the lesions. The histopathology examination confirmed the clinical diagnosis of dentigerous cysts. Longitudinal clinical and radiographic monitoring was essential to certify the regression of the lesion, as well as bone neoformation, thus promoting the eruption and maintenance of the affected permanent teeth.
Background
Several drugs are capable of promoting changes in bone metabolism. The aim of this study was to evaluate the effect of long-term low-dose aspirin (LDA) therapy on implant osseointegration.
Methods
Male Wistar rats were divided into 4 groups (n = 8/group) according to oral gavage solution received prior (42 days) to the implant surgery on the tibia. The control group was treated with saline solution for 7 (CG-7) and 28 (CG-28) days. The use of low-dose aspirin was performed in AG groups (6.75 mg/kg of aspirin) for 7 (AG-7) and 28 (AG-28) days. After experimental periods, histomorphometric evaluation of bone-to-implant contact (BIC) and the bone area between threads (BABT) was performed.
Results
Reduced BIC values were detected in AG-7 (62.8% ± 17.1) group compared to AG-28 (91.9% ± 5.4), CG-7 (82.7% ± 15.2), and CG-28 (89.9% ± 9.7). BABT evaluation revealed lower values in AG-7 (70.9% ± 15.2) compared to AG-28 (95.4% ± 3.7) and CG-28 (87.1% ± 10.2) groups.
Conclusions
The treatment with low doses of aspirin promoted a discrete inhibitory effect in the early stages (7 days) of repair after implant placement, specifically in the bone deposition. However, these effects were not detected in the late stages (28 days), considering BIC and BABT parameters.
This case report showed an AOT in a 12-year-old female patient referred for orthodontic-surgical of both impacted right mandibular canine and lateral incisor. Cone beam computed tomography revealed a well-defined mixed hyperdense/hypodense lesion, involving the crown of the mandibular lateral incisor. The surgery consisted in surgical exposure of the mandibular right canine and lateral incisor, bonding of the lateral incisor for orthodontic traction and curettage of the mandibular lesion. Histopathological examination revealed several columnar epithelial cells with minimal stromal connective tissue, lobular pattern and rosettes and duct-like structures, confirming the diagnosis of AOT. After, the patient was referred for orthodontic traction of the impacted teeth. At 1 and 3-year postoperatively, follow-ups examinations showed extensive bone repair, resolution of the tooth-retention and absence of recurrence. Although AOT is an uncommon lesion in the mandible, it should be considered in the differential diagnosis of the mixed profile lesions in this region.
Das especialidades, a cirurgia bucomaxilofacial é aquela em que o profissional está mais exposto a acidentes e complicações. Assim, uma vez indicada a cirurgia, é importante que se faça um planejamento cirúrgico detalhado baseado no exame físico e em exames de imagem, a fim de evitar iatrogenias. Objetivo: Relatar um caso atípico e raro de fratura de agulha de sutura após a realização de sutura em cirurgia oral menor. Relato de caso: Paciente do gênero feminino, com a presença de uma agulha de sutura em espaço parafaríngeo, removida por procedimento cirúrgico sob anestesia geral. Conclusão: A paciente evolui bem, sem complicações. Se ocorrer uma fratura, complicações secundárias podem ser evitadas enviando prontamente o paciente para um hospital especializado, para evitar o movimento de fragmentos em regiões mais profundos do tecido.
Introduction: Among the specialties, the maxillofacial surgery is one in which the professional is more exposed to accidents and complications. Thus, once the surgery is indicated, it is important to have a detailed surgical planning based on the physical examination and imaging examinations, in order to avoid iatrogenies. Objective: To report an atypical and rare case of suture needle fracture aftersuturing in minor oral surgery. Case report: Female patient, with the presence of a suture needle in parapharyngeal space, removed by surgical procedure under general anesthesia. Conclusion: The patient progresses well, without complications. Thus, if a fracture occurs, secondary complications can be avoided by promptly sending the patient to a specialized hospital to prevent the movement offragments in deeper tissue regions.
