This study was conducted to investigate practice rate of dental hygiene assessment and to understand the performance ratio according to hospital type. A questionnaire survey was conducted on 195 dental hygienists, and the dental hygiene assessment items examined were 6 types of dental history, medical history, vital signs measurement, extraoral examination, intraoral soft tissue examination, andtissue examination. As a result of the study, the item with the highest percentage of performers was 92.8% of dental history, and the lowest item was extraoral examination 57.9%. And, dental clinics were higher than dental hospitals and university hospitals in all dental hygiene assessment categories, and in particular, performance rates of extraoral examination and intraoral soft tissue examination were higher in dental clinics. Considering the overall high rate of dental hygiene assessment through this study, it is necessary to discuss the legal work of dental hygienists and to reflect the insurance fee.

Objective : This prospective study sought to verify the stability of three types of short implants measuring 7mm or less. Materials and methods : Implants measuring 7mm or less were placed in patients at multicenter dental clinics in Korea, China, Taiwan, and Singapore. Initial stability, intraoperative and postoperative complications, crestal bone loss, and survival rate of the implant were prospectively evaluated. Results : The primary stability of a 6-mm implant was lower than that of a 7-mm implant. The marginal bone loss of short implants measuring less than 7mm was minimal. Complications such as wound dehiscence, implant mobility, and peri-implant mucositis developed, and these were associated with initial implant failure. The short-term survival rate of 6-mm implant was 93.7%, and that of 7-mm implant, 96.6%. Conclusion : Short implant for the mandible with insufficient height for the residual ridge can be selectively used. Poor primary stability and wound dehiscence can cause osseointegration failure and alveolar bone loss.

It is generally accepted that dental procedures can be the causes of dental anxiety, and dental anxiety is described as a significant influence on physical reactions, which may complacate the dental treatment, and there has been much emphasis in the control of it. So it is very useful for dentists to know the degree of anxiety of their patients for the treatment planning and prevention of unexpected emergent state which may be caused by severe anxiety. For the study of the degree of the dental anxiety, 1,041 patients of the Dept. of Oral Diagnosis of S.N.U. hospital and some private clinics were evaluated for dental anxiety by means of dental anxiety scale questionaire. The results were as follows : 1. The mean value of 517 male patients and 524 female patients were are $9.31\pm2.76 and 12.01\pm2.78$ in respective. 2. There was no significant alteration by age and educational backgrounds. 3. Four male patients and nineteen female patients achieved scores ranging from 17 to 20 which have been known to dental phobics.

This clinical report describes hemisection and endodontic treatment of first molar tooth and mandible fracture repair in a dog. A 10 years old spayed female shih-tzu was diagnosed as left mandibular fracture by oral examination and dental radiography. First, partial odontectomy of mesial root of mandibular first molar placed in fracture line was performed, and then endodontic treatment of distal root and bone graft in extraction site was performed. Thereafter the fracture region was fixed with interdental wiring and acryl resin splint. Mandibular fracture site was healed without any complications, observed for 19 weeks follow-up period. Upon this result, this case is proving that fractured mandible can be treated successfully with hemisection followed by bone graft, interdental wiring and acryl resin splint to preserve the remaining tooth for mastication rather than tooth extraction.

The purpose of this study was to investigate the performance of dental infection control. This survey was performed on 158 of the dental hygienist in certain areas. The research was performed using a self-reported questionnaire and interview method from June to July, 2014. The collected data was analyzed by PASW Statistics ver. 18.0. Guideline of infection management, infection controller, regular infection control training, Sterilization of the handpiece/per head resulted 57~74% for dental hospital. It was higher than 13~20% for dental clinics (p<0.05). Infection control guidelines and vaccination recognition of dental were more performed in dental hospital. Patient's hand hygiene performed, tooth brushing before treatment, cross infection educational experience was less than 20%, research cooperation of medical history was over 90% (p<0.05). Performing rate of the dental hospital workers were investigated higher in protective personal devices, infection control of treatment room. A correlation analysis about institutional support, infection control of dental hygienists, patients with infection control cooperation showed a positive correlation statistically significant. Infection control can be enhanced when the medical staff, the patient, the organization combined cognitive and practice. Dental hygienist is required to recognize and practice the infection control guidelines through continuing education.

Background: Digital panoramic dental X-ray equipment (PDX) is frequently used by patients and dental workers for diagnosis and examination in dental institutions; however, infection control has not been properly implemented. Therefore, in this study, we aimed to systematically review the potential risk of cross-infection in the dental environment by investigating the contamination level of general aerobic bacteria and Staphylococcus aureus, which are important in hospital infections, in PDX areas that people mainly contact. Methods: This survey was conducted from March to May 2023 and covered one general hospital, three dental hospitals, and nine dental clinics equipped with PDX. Bacteria samples were collected from the left-handle, right-handle, forehead support, and head side support as the patient's contact areas, as well as the X-ray exposure switch and left-click mouse button as the dental hygienist's contact areas of the PDX. The collected bacteria were spread on Petrifilm, and colonies formed after 48 hours of culture were counted. Results: General aerobic bacteria and S. aureus were detected in all areas investigated. Significant differences in bacterial counts between different regions of the PDX were observed in both groups (p<0.001). The detection rates of general aerobic bacteria (p<0.001) and S. aureus (p<0.001) were significantly higher in the contact areas of patients than those of dental hygienists. A positive correlation was observed between the forehead and the temple region in terms of general aerobic bacteria and S. aureus detection (r=1) (p<0.01). Conclusion: Taken together, the presence of many bacteria, including S. aureus, detected in PDX indicates that PDX has a potential cross-infection risk. Our results therefore highlight the need for the development of appropriate disinfection protocols for reusable medical devices such as PDX and periodic infection prevention training for hospital-related workers, including dental hygienists.

Objectives: The purpose of the study was to investigate the satisfaction towards clinical training institution according to clinical practice contents in the dental hygiene students. Methods: A self-reported questionnaire was completed by 382 dental hygiene students of five colleges in Busan, Ulsan, and Gyeongsangnam-do from August 20 to September 30, 2013. The data were analyzed using SPSS WIN 20.0 program for t-test, one-way ANOVA, and Pearson's correlation analysis. The questionnaire consisted of the general characteristics of the subjects and the satisfaction towards the clinical training institution. The satisfaction was composed of 44 questions including the general satisfaction, practice contents, practice guide, training time of practice, training environment, practice evaluation, and personal relationship by Likert 5 point scale. Results: The students were most satisfied with the practice contents of the dental university hospitals. The dental hospital and dental clinics were the most satisfied choice in the personal relationships. Public health center dental clinics bestowed the students with the most satisfied practice guidance, time, environment, and evaluation. Practice contents and practice time were the most influential factors to dental hygiene department satisfaction to the students. Conclusions: In order to enhance the clinical practice satisfaction, it is necessary to have the continuous relationship with the clinical training institution. The practice satisfaction is influenced by the contents and environment of the clinical training institution.

Objectives : This study is designed to identify the need for an efficient infection control plan in the curriculum of Dept. of Dental Hygiene and encourage dental hygienists to be more attentive to infection control by analyzing their personal protective measures, hand-washing frequency and other factors relating to infection control. Methods : A survey was conducted of 471 dental hygienists in general hospitals, dental clinics and dental hospitals in City of Busan and Gyeongsangnam-do from December 20, 2009 to February 21, 2010. Results : 1. Among those who worked for more than 11 years, personal protection (3.79) and hand-washing frequency (3.90) factors were rated high (p<0.05). 2. When surveyed by workplace, personal protection was high in general hospitals (3.75) while hand-washing frequency was high in dental clinics (3.74). 3. Among those who received infection control education more than three times, personal protection (4.07) and hand-washing frequency (3.80) were high (p<0.05). 4. Personal protection-related factors were general hospital workers, necessity of infection control education and awareness on infectious disease (p<0.05), while factors associated with hand-washing frequency were number of patients per day, whether or not infection control-related class is given at school, necessity of infection control education and awareness on infectious disease (p<0.05). Conclusions : To enhance awareness of infection control, it may be necessary to addan infection control-related class to the school curriculum and provide the necessity of conducting continuous and systematic infection control education through newly entering staff training and education of dental practitioners.

Purpose: We investigated correlations between the findings of oral examinations and panoramic radiography in order to determine the efficacy of using panoramic radiographs in screening examinations. Methods: This study included patients who visited dental clinics at National Health Insurance Service (NHIS) Ilsan Hospital for checkups during 2009-2015 and underwent panoramic radiographic examinations within 1 year prior to the oral examinations. Among the 48,006 patients who received checkups, 1,091 were included in this study. The data were evaluated using the Cohen kappa and interrater agreement coefficients. Accuracy, sensitivity, and specificity were calculated using data from the panoramic radiographs as true positive diagnoses. Results: The interrater agreement coefficient for occlusal caries was 28.8%, and the Cohen kappa coefficient was 0.043 between the oral and panoramic radiographic examinations. Root caries and subgingival calculus were only found on the radiographs, while gingival inflammation was found only by the oral examinations. The oral examinations had a specificity for detecting occlusal dental caries of 100%, while their sensitivity for proximal dental caries and supragingival calculus was extremely low (14.0% and 18.3%, respectively) compared to the panoramic radiographic examinations. The oral examinations showed a relatively low sensitivity of 66.2% and a specificity of 43.7% in detecting tooth loss compared with panoramic radiography. Conclusions: Panoramic radiography can provide information that is difficult to obtain in oral examinations, such as root caries, furcation involvement, and subgingival calculus, which are factors that can directly affect the survival rate of teeth. It therefore seems reasonable and necessary to add panoramic radiography to large-scale health checkup programs such as that provided by the NHIS.

Eagle's syndrome is the manifestation of elongated styloid process that is not a common entity in dental clinics. Without the knowledge of this syndrome misdiagnosis can be made and therefore differential diag-nosis with other diseases of oral and maxillofacial area is required. The symptoms of elongated styloid process are cervical pain, foreign body sensation, dysphagia and pharyngeal pain. A 27 years old male vis-ited our hospital. He had cervical pain with unilateral facial nerve palsy. Along with meticulous clinical examinations, 3D-CT, Plain radiographic studies were used to make the diagnosis. In computed tomogra-phy, Lt. styloid process was elongated and fractured. Patient have undergone surgical resection of elongat-ed styloid process and have been carefully observed. Characteristically, preoperative facial nerve palsy showed rapid postoperative recovery. The other clinical symptoms that were present in the initial visit were diminished. The purpose of this article is to report a case of Eagle's syndrome presenting unilateral facial nerve palsy that was treated with transoral surgical approach with literature review.
