The purpose of this study was to observe the potentiality of a mixture of antibiotics to relieve the endodontic and periapical infections in primary teeth. A mixture of metronidazole, ciprofloxacin, and minocyclin in distilled water or in a root canal sealer were used to disinfect the infected endodontic and periapical lesions. For application of this mixture, medication cavities were prepared at orifices of root canals by using the $Fissurotomy^{(R)}$ burs(S S White, USA). The cavities and bottom of pulp chamber were filled with antibiotics mixture. In this cases, clinical symptoms were improved following a single application of that mixture. Gingival swelling, pain, and fistulae were disappeared within a week. More long term evaluation will be needed. Although there were no reports of side effects, care should be taken if children are sensitive to antibiotics. Within the limitations of this case, the mixture of 3 antibiotics provided an excellent improvement in treatment of infected primary teeth under the physiologic root resorption.

Dens evaginatus is an anomalous tooth development arising during morphodifferentiation. It is most often reported in premolar, and familial occurrence has been reported. The primary dental complication of dens evaginatus is fracture or wear of the tubercle which leads to pulp exposure, pulpal necrosis and periapical infection. Pathosis of the pulp can occur before complete root formation with cessation of root development. A rational and conservative approach to the management of dens evaginatus in vital teeth includes early diagnosis and treatment to prevent fracture or attrition of the tubercle. This treatment would include careful sequential grinding, pulp capping, preventive resin restoration. When presented with a case of dens evaginatus in a nonvital tooth with incomplete root development, the treatment of choice has been extraction, apexification. We report two cases of dens evaginatus that appear in two sisters. In the elder, a periapical lesion on radiographs is shown, and it is treated by calcium hydroxide apexification. The other sister is early recognized of dens evaginatus, it is treated using glass ionomer cement reinforcing with sequential grinding.

Recently, the number of stray dogs is proportionate to the increase of the number of the companion dogs. Sarcoptic scabiei var canis, causing scabies, is one of the most important canine zoonotic arthropods in Korea and around the world. Thus, we have tried to know the prevalence of canine scabies in the stray dogs in Korea. A total of 565 stray dogs were collected from the rescue centers all over the country from Jan. 2006 to Dec. 2006. They were grouped with euthanasia or natural death and examined for the gender and age estimated by dental formula. To identify the lesions, the whole body was grossly examined and tested pathologically. Thirty two (5.66%) of 565 dogs were diagnosed as canine scabies. Dogs from urban areas had fewer scabies (0.62%) than those of rural areas (12.5%). Prevalence of scabies in male and female dogs was no difference as 5.96% and 5.25%. Euthanasia group showed higher prevalence (6.48%) than natural death group (2.44%) in scabies. Old dogs over five years showed lower infestration (1.82%) in scabies. In histopathological findings, there were mites in the burrows formed in the subcorneal space. Acanthosis, hyperkeratosis with crust, and vascular dilatation were main findings. One hundred thirteen (20%) of 565 stray dogs were diagnosed to have skin disease. Among them, canine scabies is the most prominent ectoparasite as 5.66 %. With previous reports on human infection in Korea, canine scabies must be regarded as the important zoonotic canine skin disease. Accordingly, for the human and canine hygiene it is imperative that stray dogs with skin problems are segregated and tested for the parasites to treat properly as soon as arriving at rescue shelter.

Moderns have desire likely to be further good-looking concomitant with a qualitative advancement of the life. With one of this phenomenon, an orthognathic surgery performing at the dept. of oral and maxillofacial surgery have been becoming a more extensively. It's possible to occur many complications during the operations and especially, an excessive bleeding of those may be fatal and so a transfusion is performing for the prevention &management of that. But, because of the rate of increase of an blood-born infection like AIDS via transfusion, nowadays an autologous blood transfusion is interesting to us. We made a comparative study of an amount of blood loss &transfusion using hemoglobin value after classifying the orthognathic surgeries from Feb. '97 to Mar. '98 in single-jaw and doublejaw surgery. And we intended to set a standard against of a routine preoperative cross-matching deciding the amount of predictive homologous blood transfusion according to operative method. Simultaneously, we studied the realization &effectiveness of autologous blood transfusion with some cases, so would like to present. Results: 1. Single-jaw operation can be performed without blood transfusion or with homologous blood transfusion through only blood typing & screening. 2. We commonly transfuse two units of blood with double-jaw operation and an autologous blood transfusion has much more advantage than an homologous blood transfusion. 3. We can reduce charge associated with blood transfusion through precisely preoperative evaluation of patients and proper type of blood transfusion.

An augmentation of the maxillary sinus floor facilitates placement of dental implants in the posterior atrophic maxilla. However, a maxillary sinus augmentation has potential complications that can lead to early failure and loss of the bone graft. One specific complication is sinus membrane perforation. Especially, large perforations may cause loss of the graft materials into the sinus and infection, so, early failure of the sinus lift. Attempts at managing sinus membrane perforations are difficult because of the limited access to them and friability of the thin Schneiderian membrane. Repair of sinus membrane perforations intraoperatively may be performed using a variety of techniques and materials, including sutures, collagen membranes, fibrin glue. Inspite of various repair technique, as has been reported extensively in the literature, large perforations represent an absolute contraindication to the continuation of surgery. But, we obtained clinically favorable results in cases that show repair of the perforated sinus membrane with a micro-suture technique by 4X Loupe ($Surgitel^{(R)}$ Loupe, General Scientific Corporation) in large perforation. The objective of this presentation is to report of several cases of repair of the perforated sinus membrane with micro-suture technique using 7.0 or 8.0 suture materials, to make a brief review of the literature about various technique managing perforated sinus membrane.

Implantation of allografts has increased widely with not only the availability of many allogenic bone but also allogenic soft tissues. The aim of tissue banking is to provide surgeons with safe tissues compatible with their intended clinical application. The incidence of tissue transplant-transmitted infection is unknown and can only be inferred from prospective studies. The possibility of donor-to-recipient disease transmission through soft tissue transplantation can be considered by reviewing the risk associated with other transplanted hard tissues. Viral, bacterial, and fungal infections have been transmitted via transplantation of soft tissue allografts such as skin, cornea, dura, pericardium. fascia lata, and heart valves. Corneas have transmitted rabies, Creutzfeldt-Jakob disease (CJD), hepatitis B (HBV), cytomegalovirus (CMV), herpes simplex virus (HSV), bacteria, and fungi. Heart valves have been implicated in transmitting tuberculosis, hepatitis B. HIV-1 and CMV. CJD has been transmitted by dura and pericardium transplants. Skin has transmitted CMV, bacteria, and fungi. Cadaveric skin, pericardium, dura, and fascia lata have been used in dental patients with intra-oral soft tissue injuries and GBR. This study is review of the considering transmission of infectious disease in allogenic soft tissues and guidelines of reducing the risk. Prior to use, many tissues are exposed to antibiotics, disinfectants, and sterilants, which further reduce or remove the risk of transmitted disease. Because some soft tissue grafts cannot be subjected to sterilization steps, the risk of infectious disease transmission remains and thorough donor screening and testing is especially important.

Background: Osteoradionecrosis is a delayed complication from radiation therapy which causes chronic pain, infection and constant deformity after necrosis. Most of the osteoradionecrosis occurs spontaneously or after the primary oncologic surgery, dental extraction or by trauma of prosthesis. The treatment of osteoradionecrosis relies on both conservative measures and surgical measures. The fibular osteocutaneous free flap has become more popular choice for reconstruction of maxillofacial defects as a treatment of osteoradionecrosis. Methods: We presented our experiences from 7 patients with osteoradionecrosis who have had reconstruction surgery with fibular osteocutaneous free flap at National Cancer Center during the recent 5 years. We performed segmental mandibular resection with fibular osteocutaneous free flap for all 7 patients of advanced osteoradionecrosis who were not controlled by conservative treatment such as wound irrigation, debridement, and antibiotics. Results: A wide range of techniques were available for the reconstruction of composite defects resulted from the treatment of advanced mandibular osteoradionecrosis. Significant improvement was noted in relieving pain and treating trismus after the surgery however difficulty in swallowing and xerostomia showed less improvement. Conclusions: We concluded that fibular osteocutaneous free flap can be performed safely in patients with osteoradionecrosis and yields positive outcomes with significantly increased success rate. The fibular osteocutaneous free flap was our preferred choice for the mandibular reconstruction due to its versatility and predictability.

Nine cases of maxillary sinus aspergillosis during a period from February of 1992 to June of 2000 were investigated to analyze the clinical, radiologic and pathologic features. Maxillary sinus aspergillosis is rare disease, but it was increasing tendency with overuse antibiotics, steroid hormones, and anticancer agents. Aspergillosis of the maxillary sinus may occur as a chronic disease in an otherwise healthy person. The clinical features of maxillary sinus aspergillosis were similar to the non-fungal, chronic sinusitis. Intrasinus calcification is known to be a characteristic feature of maxillary sinus aspergillosis. It is suggested that excess root filling materials containing zinc oxide in the maxillary sinus could favour the formation of a local, non-invasive maxillary sinus aspergillosis. And this "dental" model of pathogenensis of maxillary sinus aspergillosis is an alternative to the widely accepted concept of spore inhalation and "aero-genic" pathogenensis of maxillary sinus aspergillosis. The radical surgery such as Caldwell-Luc operation was one of the most effective treatment modalities. Our results of this study indicate that maxillary sinus aspergillosis might occur mainly in healthy individuals rather than debilitating patients. It could efficiently treated with radical surgery alone without the antifungal agents. 4 cases were suspected to be related with teeth extraction and endodontic treatment. There were no recurrence in all cases.

The pulp infection of primary tooth is often caused by dental caries or trauma. But, if it is not managed properly, it can be produce the periapical lesion. The periapical lesion can cause some complications such as enamel hypoplasia, displacement, root dilaceration and impaction. Treatment options of displaced permanent successor are clinical and radiological follow-up after extraction of primary teeth, surgical opening, orthodontic traction, transplantation and extraction. In these cases, the premolars with abnormal eruption path caused by periapical lesion of the primary tooth have shown successful spontaneous eruption just as a result of extraction of infected primary tooth and space maintenance.
