The purpose of this study was to provide basic data to standardize the clinical dental hygiene curriculum, based on analysis of current clinical dental hygiene curricula in Korea. We emailed questionnaires to 12 schools to investigate clinical dental hygiene curricula, from February to March, 2017. We analyzed the clinical dental hygiene curricula in 5 schools with a 3-year program and in 7 schools with a 4-year program. The questionnaire comprised nine items on topics relating to clinical dental hygiene, and four items relating to the dental hygiene process and oral prophylaxis. The questionnaire included details regarding the subject name, the grade/semester/credit system, course content and class hours, the number of senior professors, and the number of patients available for dental hygiene clinical training purposes. In total, there were 96 topics listed in the curricula relating to clinical dental hygiene training, and topics varied between the schools. There was an average of 20.4 topic credits, and more credits and hours were allocated to the 4-year program than to the 3-year program. On average, the ratio of students to professors was 21.4:1. Course content included infection control, concepts for dental hygiene processes, dental hygiene assessment, intervention and evaluation, case studies, and periodontal instrumentation. An average of 2 hours per patient was spent on dental hygiene practice, with an average of 1.9 visits. On average, student clinical training involved 19 patients and 26.6 patients in the 3-year and 4-year programs, respectively. The average participation time per student per topic was 38.0 hours and 53.1 hours, in the 3-year and 4-year programs, respectively. Standardizing the clinical dental hygiene curricula in Korea will require consensus guidelines on topics, the number of classes required to achieve core competencies as a dental hygienist, and theory and practice time.

Purpose : Orbital cellulitis is rare, but it could be from the serious complication of sinusitis in children. It is often difficult to distinguish periorbital cellulitis from orbital cellulitis. The purpose of this study is to describe the clinical features of orbital and periorbital cellulitis in a pediatric population and to assess the predisposing factors and their complications. Methods : Forty-one patients aged 18 years and younger who were admitted between January 2000 and December 2006 to Hanil General Hospital and Kyunghee University Hospital with orbital or periorbital cellulitis. The retrospective analyses included clinical characteristics of orbital and periorbital cellulitis, dermographics, past history, predisposing factors, clinical presentations, treatments, and complications. Results : Among 41 patients, 34 patients had periorbital cellulitis, 7 patients had orbital cellulitis. While paranasal sinus disease was the most common predisposing cause in orbital cases, skin lesion, insect bite, dacrocystitis and conjunctivitis were the common causes in periorbital cases. In comparison with periorbital cases, orbital cases had higher level of white blood cell count, erythrocyte sedimentation rate, and C-reactive protein. Blood cultures were taken in 23 patients, but only one had Staphylococcus aureus from blood. Only one case had surgical incision and drainage and recovered without complications. Conclusion : From the results of our data, when patient shows erythematous swelling of periorbital area with opthalmoplegia, chemosis and proptosis, orbital CT scan is required to make diagnosis of orbital cellulitis. Most cases of orbital cellulitis can be treated successfully without surgical intervention. If there is no clinical improvement, repeated CT scan and/or surgical intervention should be considered.

This study analyzed the tooth brushing behavior and oral health status of foreigner immigrant workers and obtained the following results. Statistical significance based on different general characteristics. Gender, educational background, period of stay, health insurance, medical expense coverage, and whether or not one has friends or regular gatherings were significant traits for frequency, while age, marital status, income, and health insurance were traits for part (p<0.05). Statistical significance (p<0.05) was found in marital status and health insurance for time used to brush teeth, period of stay and whether or not one attends a regular gathering for tooth brushing training, and gender, educational background, period of stay, roommate status, medical expense coverage, and whether or not one attends a regular gathering for supplemental oral product usage. The averages of decayed, missing, and filled teeth (DMFT) index and community periodontal index of treatment needs (CPITN) for general characteristics were 6.98 and 3.03 respectively, and gender, roommate status, income, health insurance for DMFT index, and gender, age, marital status, educational background, roommate status, income, health insurance for CPITN were statistically significant (p<0.05). Tooth brushing frequency and part showed statistical significance (p<0.05) for DMFT index based on tooth brushing behavior, while tooth brushing part and time used to brush teeth were significant for CPITN. DMFT index was high at 8.34 for '3 times or more' in tooth brushing frequency, while DMFT index was high at 7.91 and CPITN was low at 2.94 for tooth brushing part. '3 minutes or longer' in time used to brush teeth was the lowest in CPITN at 2.88. As a result of analyzing the correlation between tooth brushing behavior and DMFT index, CPITN, tooth brushing frequency and part in DMFT index, and tooth brushing part and time used to brush teeth in CPITN showed significance (p<0.05). Based on the above results, we must promote the significance of brushing teeth and implement continuous training for correct tooth brushing management to enhance the oral health of foreign immigrant workers.
