Chemical burns onto oral mucosa which are infrequent, may result from contact with a wide variety of chemical agents. The degree of injury depends on the chemical, its concentration, duration of contact, and the natural penetrability and resistance of the tissues involved. Chemicals do not usually “burn”in that they do not cause destruction by hyperthermic activity. Rather, they damage tissue by causing coagulation of protein by one of several processes, reduction, oxidation, desiccation, corrosion, or vesication. Paraquat(Gramoxon) is the most frequently agricultural chemicals that induce the severe toxic reactions onto the organs of human body in Korea. The toxic reaction are composed of pulmonary edema and fibrosis, formation of hyaline membrane, inflammatory reaction and bleeding tendency, owing to the cell damage by the production of superoxide radicals. The contents of essential treatment in paraquat intoxication are commonly airway and breathing maintenance, gastric lavage, much hydration and diuresis, hemoperfusion and medications for the removal of the chemicals and the prevention of various complications. The sedative oral dressings, such as, orabase ointment application, warm saline gargling, lidocaine viscous gargling and oral gargling by the mixed solutions(tetracycline, prednisolone and 10% dextrose water) are important for the improvement of chemical oral mucositis and the comfortable feeding of diet. The authors managed properly two cases of oral chemical mucositis that were occurred by the incorrect use of agricultural chemicals(paraquat) and report the cases with the review of literatures about care of the chemical intoxication and oral mucositis.

The side effects of head and neck radiation therapy include mucositis, xerostomia, loss of taste, radiation caries, oral infection, osteoradionecrosis and trismus. When a patient is arranged to begin head & neck radiotherapy, oral pathologic lesions are examined and managed for the prevention of oral complications. The advanced odontogenic infection should be especially controlled before the radiotherapy and the patient must be instructed for proper oral prophylaxis. Generally the more conservative treatments, such as, scaling, restoration, endodontic treatment, are the care of choice and dental extraction is performed in advanced periapical and periodontal pathologic conditions. If the dental extraction should be done, the radiotherapy consequently will be delayed until there is epithelium covering the extraction socket, leaving no exposed bone. The cancer patient with severe emotional stress pray for the early radiation therapy, in spite of possibility of the recurrent odontogenic infectious lesions. So, the authors attempted to do the early radiation therapy by the conservative endodontic drainage and surgical incision & drainage without extraction of the infected teeth, and resulted in relatively good prognosis without the severe side effects of head and neck radiotherapy.

The purpose of this article is to confirm the longterm biocompatibility of national Avana implant and international ITI implant in dogs. At the fourth month after extreaction of the mandibular third and fourth premolar in three dog, both implants were inserted using careful atraumatic technique and prosthetic abutments were applied onto the implants in three months. After that, the implants were examined by naked eye and radiographic image every three months during 1 year, for detection of the complications, such as, mobility, bone resorption and wound infection. At 1 year after application of prosthetic abutment, the dogs were sacrificed for the histopathologic analysis by light microscope. The results obtained were as follows; 1. All implants had the ralatively good prognosis without mobility, wound infection and moderate bone resoprtion, in clinical and radiological evaluation during one year. 2. The all histopathologic specimens at one year after application of prosthetic abutment onto the implants showed the distinct osseointegration between implant system and bone, with projection of new bone apposition onto the peri-implant tissue. But Avana implants had the less osseointegration than ITI implants in the cancellous and marrow layer of jaw bone. 3. The all histopathologic specimens at one year after application of prosthetic device showed the firm junction by dense connective tissue pattern between the implant and the gingival portion. But Avana implants had the less firmer junction than ITI implants. 4. The authors confirmed that Avana implant and ITI implant have more higher tissue biocompatibility in dental implantation, but ITI implant has the more osseointegration than the Avana implant.

The purpose of this study was to assess relative tooth abrasivity and to measure effective fluoride concentration of dentifrices selling in Korea for help consumer's selection of suitable dentifrice. Assessment of the abrasion on tooth produced by different dentifrices were carried out on bovine teeth in the laboratory and tested by radioactive dentin abrasion method. And total soluble fluoride concentrations within the dentifrices was determined using fluoride ion selective electrode with standard curve obtained from standard solutions of known fluoride concentration. 10 dentifrice samples were stored at 49t for 15 weeks and the measurements were made for each dentifrice in 1 week, 2 weeks, 3 weeks, 13 weeks and 15 weeks and 11 dentifrice samples were stored at 40.6C for 3 weeks and the measurements were made for each dentifrice in 1 week and 3 weeks. Tooth abrasivity of selling dentifrices is suitable for toothbrushing but dentifrice which recommended for patient who have tooth abrasion or erosion was somewhat high abrasivity level. Effective fluoride concentrations of selling dentifrices were maintained generally optimal level. But some dentifrices contaning CaCO_(3), as abrasive were decreased as time elapsed. It was suggested that relative tooth abrasivity must be marked on package and fluoride level should be maintained acceptable level in dentifrices for consumer's selection of suitable dentifrice.

The aim of this study was to assess the effect of mouthrinse products which contained 0.03% sodium fluoride, 0.05% cetylpyridinium chloride(CPC), 0.04% pine leaf extracts and 0.04% green tea extracts. The negative control was distilled water contained no antibacterial agents. The in vivo study used case control, double-blind and crossover design in which 40 healthy subjects aged from 20 to 25 participated. On baseline, subjects received a scaling and polishing to reduce plaque index to 0 and commenced rinsing three times and toothcleansing twice daily. Rinsing time was 30 seconds. Plaque, gingivitis, halitosis and the number of S. mutans(CFU/㎖) were scored at baseline, after 2 weeks, after 4 weeks and after 6 weeks. Plaque and gingivitis were score by index and halitosis by halimeter. To compare the microhardness data of differently stored enamel surfaces the in vitro study used pH Cycling Model. Each 19 bovine enamel specimens were given 17h demineralization, 0.25h immersion in mouthrinse products and control, and 6h remineralization buffer solution for 48h and 96h. Gingivitis, halitosis and S. mutans growth of the mouthrinse group were more reduced significantly than control group at 2 weeks(p<0.05). The microhardness of enamel surfaces were also more decreased in mouthrinse products than in distilled water(p<0.05).
