Chronic invasive fungal sinusitis (CIFS) is a relatively rare disease which occurs in immunocompetent or immunocompromised patients. We report a case of CIFS in ethmoid sinus with concurrent fungal ball in maxillary sinus. After surgical debridement and antifungal therapy, CIFS recurred with submucosal invasion in nasopharynx and osteomyelitis of clivus. Although CIFS encompasses a slowly progressing invasive fungal disease but potentially aggressive. It should be noted that CIFS could progress and extend through submucosal route without evidence of mucosal lesion.

Purpose: To compare the case of widespread maxillary osteomyelitis treated through different approach. Method: We report the two case of osteomyelitis. In a case, we had gradually removed the small amount of sequestrum for several times. In the other case, intended Le Fort I fracture was done to approach the lesion. Result: In the gradual sequestrectomy case, bone formations were found after 4 months. In the other case, after intended Le Fort I down fracture, sequestrectomy of Lt. maxilla was done with the labiobuccal alveolar bone preserved for the prosthodontic treatment.

Bisphosphonate are a class of drugs with a chemical structure which inhibit bone resorption, actually used for metastatic bone disease, osteoporosis, Paget's disease and multiple myeloma. Significant complication associated with their use is reported recently : mandibular and maxillary osteomyelitis or osteonecrosis. So we here report our case about the patient who was diagnosed of prostate cancer in 2004 April and treated with bisphosphonate(Zoledronic acid-$Zometa^{(R)}$, Novartis Co.) intravenously every 3 to 4weeks at a dose of 4mg to prevent bone metastasis, and also, the patient who came to the hospital due to the bony exposure of mandible and pain in 2006 November and was diagnosed osteomyelitis of mandible as a result of biopsy, bone scan, PET CT examination.

Radiographic diagnosis of periapical lesions is based on many factors, including anatomical limitations such as thickness of the cortical bone; positioning of the apical abscess to the cortical bone; and is complicated by proximity to other anatomical structures and neighboring teeth. With conventional radiographs, these structures are often superimposed. Dental CBCT with its associated geometric accuracy offers accurate visualizations of the complex relationships and boundaries between teeth, related anatomical features, and their associated pathology. Its images also provide us internal tooth morphology, periodontal ligament space, the presence or absence of periapicl lesions in association wi th critical anatomical structures and maxillary sinus involement. Using 3 D imaging makes it easier for clinicians to detect, diagnosis, and develop highly effective treatment plans. Now, 4 cases of periapical and periodontal pathosis with CBCT images are to be presented including periapical abscess, furcation involvement, periapical pathosis involving maxillary sinus, and osteomyelitis. CBCT analyze specific area of interest and provides the highly detailed anatomical information. It also facilitates earlier and more accurate diagnosis, and treatment planning decisions and more predictable outcome.

For the earlier diagnosis and treatment of delayed wound healing in extraction socket, we investigated the clinical, radiographic and histopathologic features of 106 patients with delayed wound healing diagnosed by biopsy. The patients were enrolled at the Department of Oral Pathology, Chosun University Dental Hospital. Among 106 delayed wound healing diagnosed by biopsy, cysts showed most significant 25 cases (23%), osteomyelitis showed 13 cases (12%), chronic maxillary sinusitis and squamous cell carcinoma showed 12 (11%) and 11 (10%) cases, respectively. We have analyzed these lesions through relevant literatures.

A 37-year-old male with the complaint of intermittent gingival swelling and dull pain associated with the food impaction of the mandibular third molar area was referred to our department of Chonbuk National University Hospital. The dental history of the patient showed that he had extracted the maxillary left third molar without complications two years ago. Intraoral and panoramic radiographs showed diffuse increased radiopacity of the maxilla and mandible. The trabecular pattern was obliterated. Postero-anterior skull and lateral skull radiographs showed thickening of cortical bone and diffuse increased radiopacity of the skull. Additional radiographs showed similar changes in the lumbar spine, clavicles, iliac bone and femur. However, no evidence of osteomyelitis was observed clinically and radiographically. Laboratory findings showed normal values of serum calcium, phosphorus, and alkaline phosphatase. Based on the radiographic examinations and the laboratory findings, final diagnosis was made as a benign osteopetrosis.

Bisphosphonate-related osteonecrosis of the jaw (BRONJ) is a disease characterized by jaw necrosis and delayed wound healing in patients who had received bisphosphonates. Buccal fat pad (BFP) can be used as a pedicled flap in the posterior region of the oral cavity. BFP pedicle flap needs simple surgical technique and it shows less donor site morbidity and aesthetic problem than other vascularized flap. BFP pedicled flap was fed by 3 arteries-facial, internal maxillary, and transverse facial artery. Osteomyelitis was generally related with poor blood supply. Thus, rich blood supply of BFP pedicle flap can have a potential advantage to BRONJ patients. In this case report, we presented 3 BRONJ patients treated by BFP pedicle flap after sequestrectomy.

Few cases of florid osseous dysplasia has been described as a condition that characteristically affects the jaws. It usually manifests as multiple radiopaque masses distributed throughout the jaws. Confusion exists about the relationship of florid osseous dysplasia, gigantiform cementoma, chronic sclersing osteomyelitis, sclerosing osteitis or multiple enostosis. Authors experienced a case of florid osseous dysplasia of the jaws in 52-year-old female on the basis of clinical, radiographic and histopathologic findings. The characteristic features are as follows : 1. In clinical examination, there was no clinical sign and symptoms except extracted area. And there was no facial asymmetry. 2. Radiograms show round or lobular dense radiopaque masses surrounded by radiolucent bands in lower molar teeth area bilaterally. And slight increased radiopacities in maxillary molar teeth area bilaterally. There was no expansion or thinning of buccal and lingual cortical bones. There is no displacement or resorption of involved teeth. In right side of mandible, mandibular canal is displaced inferiorly due to mass. 3. Photomicrograms show densely mineralized sclerotic acellular masses with empty lacunae. Pattern is suggestive of cementum, although it could be considered sclerotic bone. In the periphery, lesion consisting of moderately cellular fibrous tissue in which globular calcified products are deposited.

Osseointegrated implants are now commonplace in contemporary dentistry. However, a number of complications can occur around dental implants, including peri-implantitis, maxillary sinusitis, osteomyelitis, and neoplasms. There have been several reports of a malignant neoplasm occurring adjacent to a dental implant. In this report, we describe 2 such cases. One case was that of a 75-year-old man with no previous history of malignant disease who developed a solitary plasmacytoma around a dental implant in the left posterior mandible, and the other was that of a 43-year-old man who was diagnosed with squamous cell carcinoma adjacent to a dental implant in the right posterior mandible. Our experiences with these 2 cases suggest the possibility of a relationship between implant treatment and an inflammatory cofactor that might increase the risk of development of a malignant neoplasm.

The purpose of this study was to isolate and identify the bacteria in chronic maxillary sinusitis (CMS) lesions from 3 patients and to determine the antimicrobial susceptibility of them against 10 antibiotics. One of them was odontogenic origin and the others were non-odontogenic origin. Pus samples were collected by needle aspiration from the lesions and examined by culture method. Bacterial culture was performed in three culture systems (anaerobic, CO2, and aerobic incubator). Identification of the bacteria was performed by 16S rRNA gene (16S rDNA) nucleotide sequencing method. To test the sensitivity of the bacteria isolated from the maxillary sinusitis lesions against seven antibiotics, penicillin G, amoxicillin, tetracycline, ciprofloxacin, cefuroxime, erythromycin, clindamycin, and vancomycin, minimum inhibitory concentration (MIC) was performed using broth dilution assay. Our data showed that enterobacteria such as Enterobacter aerogenes (30%), Klebsiella pneumoniae (25%), and Serratia marcescens (15%) were predominately isolated from the lesion of non-odontogenic CMS of senile patient (70 year old). Streptococcus spp. (40.3%), Actinomyces spp. (27.4%), P. nigrescens, M. micros, and P. anaerobius strains were isolated in the lesion of odontogenic CMS. In the lesion of non-odontogenic CMS, Streptococcus spp. (68.4%), Rothia spp. (13.2%), and Actinomyces sp. (10.5%) were isolated. The susceptibility pattern of 10 antibiotics was determined according to the host of the bacteria strains ratter than the kinds of bacterial species. Even though the number of CMS was limited as three, these results indicate that antibiotic susceptibility test must be accompanied with treatment of CMS. The combined treatment of two or more antibiotics is better than single antibiotic treatment in the presence of multidrug-resistant bacteria in the CMS lesions.
