ABSTRACT
BACKGROUND@#Brain abscess is a life-threatening condition that occurs due to complications during a neurosurgical procedure, direct cranial trauma, or the presence of local or distal infection. Infection in the oral cavity can also be considered a source of brain abscess.CASE PRESENTATION: A 45-year-old male patient was transported with brain abscess in the subcortical white matter. Navigation-guided abscess aspiration and drainage was performed in the right mid-frontal lobe, but the symptoms continued to worsen after the procedure. A panoramic radiograph showed alveolar bone resorption around the maxillary molars. The compromised maxillary molars were extracted under local anesthesia, and antibiotics were applied based on findings from bacterial culture. A brain MRI confirmed that the three brain abscesses in the frontal lobe were reduced in size, and the patient's symptoms began to improve after the extractions.@*CONCLUSION@#This is a rare case report about multiple uncontrolled brain abscesses treated by removal of infection through the extraction of maxillary molars with odontogenic infection. Untreated odontogenic infection can also be considered a cause of brain abscess. Therefore, it is necessary to recognize the possibility that untreated odontogenic infection can lead to serious systemic inflammatory diseases such as brain abscess. Through a multidisciplinary approach to diagnosis and treatment, physicians should be encouraged to consider odontogenic infections as a potential cause of brain abscesses.
ABSTRACT
There is increasing evidence that the environmental hormones may adversely affect the human body. The human reproductive system misrecognizes some of these endocrine disruptors with consequences to reproductive cell differentiation. Therefore, studies on the safety of these substances have been widely carried out to develop the science to create effective legislation to limit or prevent their use or require the development of inert, alternative substances. A few studies have reported that the oral cavity is the pathway for absorption of these substances released from plastic products or environmental hormone substances. This review suggests that the oral environment is vulnerable to exposure to environmental hormones and introduces supporting literature.

OBJECTIVE: The Purpose of the study was to investigate the bone morphogenic protein expression of rhBMP-2(recombinant human bone morphogenic protein-2) as singnaling molecule and beta-TCP(Tricalcium phosphate) as a bone substitute and carrier medium of rhBMP-2. MATERIALS AND METHODS: 16 rabbits divided into 2 group of each 8 rabbit. Two standardized bone defect, round bilateral defect was made in the cranium of the 8 rabbit of first group, and was grafted with 150~500micrometer diameter beta-TCP 0.25g in one side, which was soaked with rhBMP-2, and autogenous bone was grafted on another side as a positive control. Second group of 8 rabbit, only beta-TCP was grafted with same size and same manner. After 2, 4, 8, and 12 weeks, specimen was taken for microscopic immunohiostochemical and histomorphometric analysis. RESULT: Grafting beta-TCP with rhBMP show the early formation of the bone regenerative factor (BMP-4) and more quantity of new bone formation than only use of beta-TCP (8,12 week), even show less new bone formation than autogenous bone. CONCLUSION: The experimental study result that beta-TCP graft combination with rhBMP-2 as a delivery system is an effective with osteoinductive capacity and biodegradable properties, so that provide clinical availibility of composite use in reconstruction of bony defect.
