Objective: The purpose of this study was to reduce the burden on dental hygienists in performing dental hygiene processes in the clinic. This study systematically analyzed dental hygiene problems and dental hygiene planning according to the oral condition of patients by applying an oral health care program based on the dental hygiene process. Methods: This study analyzed influential factors of 17 dental hygiene problems and 12 dental hygiene plans according to the oral health index and charts of 185 patients. This study was approved by the Institutional Review Board (IRB No. 1041449-201801-HR-003) of Silla University. The frequency of dental hygiene problems and dental hygiene planning was analyzed and correlations among the oral health index, dental hygiene problems, and dental hygiene planning were analyzed. Results: The higher the bleeding on probing score was, the more scaling was planned. The higher the calculus rate was, the more air-jet and jaw joint disorder prevention education was planned. The higher the O'Leary index was, the more dietary education and air-jet was planned. The higher the Simplified Oral Hygiene Index was, the more air-jet and jaw joint disorder prevention education was planned. The higher the Periodontal Screening and Recording index was, the more scaling and professional tooth cleaning was planned (p<0.05). Conclusions: The burden of oral preventive duties on dental hygienists will be minimized by systematically establishing problems and planning of dental hygiene according to patients' oral health index scores. Therefore, it is expected that dental hygienist can actively use the dental hygiene process in oral health care programs.

Purpose: The aim of this study was to evaluate the erosive potential of several fruit-flavored liquors marketed in Korea by measuring pH, titratable acidity, and variations in pH utilizing an ISO method. Materials and Methods: Six fruit-flavored liquors were investigated. An orange juice and three kinds of soju were selected as the control beverage. The pH and titratable acidity of the beverages were determined by 1 M NaOH until the pH 5.5 and 7.0 (recorded as $TA_{5.5}$ and $TA_{7.0}$, respectively). All measurements were performed in triplicate. The process of ISO 28888 was used for measurement of the pH variation (${\Delta}pH$) using an under-saturated hydroxyapatite solution (screening solution) and determining the difference between the initial and final pH of the screening solution. The average ${\Delta}pH$ was determined based on 4 measurements. Results: All the fruit-flavored liquors tested in this study showed a pH lower than the critical pH for dental erosion (4.5). The average pH of the fruit-flavored liquors was 2.77 and was also lower than the pH of the soju and an orange juice (control drinks). $TA_{5.5}$ and $TA_{7.0}$ values of the fruit-flavored liquors were 4.92ml and 7.13ml, respectively. The fruit-flavored liquors showed an erosive potential capable of damaging the enamel surfaces, whereas the orange juice had the highest titratable acidity. The changes in pH determined using the screening solution confirmed that the fruit-flavored liquors had erosive potential, with ${\Delta}pH$ value of 1.53. Conclusions: The fruit-flavored liquors tested in this study might have a strong potential to erode dental hard tissues.

An appropriate amount of samples, collected from three each paddy forest, field and riverside soil near Taegu city, was suspended in sterile water and then diluted in order to isolation of antagonistic to oral cancer. The diluted samples were inoculated on separating medium in the routing spreading method. So, seven hundred and eighteen strains were isolated on HV agar and 220 strains were on methanol medium from soil samples. So, during the screening of anti-oral cancer activity from soil, we isolated microorganisms showing powerful antagonistic activity. Among them, No. 78 strain exhibited the most strongly anti-oral cancer activity. Microbiological properties were investigated by the methods described in the Bergey's Manual of Systematic Bacteriology and experimental methods of identification of actinomycetes by Hamada et al. As a result, a methylotrophic actinomycetes strain No. 79 was estimated as Amycolatopsis sp. based on taxonomic studies.

Since the first report of a nasal septal abscess (NSA) from a dental origin (1920), six articles have been published in the English literature to date. The most common cause of NSA is an infection of the nasal septal hematoma after trauma. This is a report of an uncommon cause of NSA with a dental origin. A PubMed search performed regardless of year and country using the terms ("nasal septal abscess") OR ("nasal septum abscess") initially yielded 229 articles. After screening, seven articles (eight patients) were selected. Addition of two related articles produced a total of nine articles (10 patients) to be included. The age of the included patients ranged from 7 to 69 years (mean, 32.82 years; standard deviation, ±23.86 years). The sex composition was as followed: males (n=7; 63.6%), females (n=4; 36.4%). Dental histories were various: periapical lesions, caries, extraction, endodontic therapy, and cystic lesions. The maxillary incisor dominated as the tooth of origin. Early diagnosis and treatment of NSAs are important to avoid not only facial deformity, but also severe complications (e.g., intracranial infection). If NSA is suspected in patients without facial trauma, the possibility of a dental origin, especially from the maxillary incisor area, should be considered.

The purpose of laboratory tests in the field of oral medicine can be divided into two categories: (1) medical evaluation of patients with systemic diseases that are planning to receive dental care and (2) diagnosis of patients with certain oral diseases. First, laboratory tests are commonly used to evaluate patients with systemic diseases who need dental management. A combination of multiple tests is usually prescribed as a test panel to diagnose and assess a specific disease. Test panels closely related to oral medicine include those for rheumatoid arthritis, connective tissue disease/lupus, liver function, thyroid screening, anemia, and bleeding disorders. Second, laboratory tests are used as auxiliary diagnostic methods for certain oral diseases. They often provide crucial diagnostic information for infectious diseases caused by bacteria, fungi, and viruses that are associated with pathology in the oral and maxillofacial regions. Laboratory tests for infectious diseases are composed of growth-dependent methods, immunologic assays, and molecular biology. As the field develops, further application of laboratory tests, including synovial fluid analysis in temporomandibular joint disorders, salivary diagnostics, and hematologic biomarkers associated with temporomandibular disorders and orofacial pain conditions, is currently under scrutiny for their reliability as diagnostic tools.
