Objective: The purpose of this study was to evaluate on the antimicrobial effect on the periodontal pathogens and anti-inflammatory effect of Eriobotryae folium. Eriobotryae folium are constituent herbs of Gagamgamroum, which has been used for a long time in oriental medicine as a herbal medicine for treating halitosis and toothache. Method: Eriobotryae folium was prepared by extracting medicinal herb with water. We investigated antimicrobial activity by the minimum inhibitory concentration (MIC) test. We also investigated inhibition of $IL-1{\beta}-induced$ collagenase (mmp-1), stromelysin-1 (mmp-3), interleukin-6 gene expression in human gingival fibroblasts using RTPCR analysis. Result: The antimicrobial effects of Eriobotryae folium was evaluated with MIC against periodontopathogens; Porphyromonas gingivalis 2561, W50, A7A1-28, 9-14K-1, Prevotella intermedia 28, and Actinobacillus actinomycetemcomitans Y4. MICs of Eriobotryae folium were 1.25 mg/ml, 2.5 mg/ml, 0.625 mg/ml, 1.25 mg/ml, 10 mg/ml and 10 mg/ml. The anti-inflammatory effect of Eriobotryae folium was evaluated with influence of herbs on the $IL-1{\beta}-induced$ expression of mmp-1, mmp-3, and interleukin-6. $IL-1{\beta}$ increased mmp-1, mmp-3, and interleukin-6 mRNA levels. Eriobotryae folium significantly inhibited $IL-1{\beta}-induced$ mmp-1, mmp-3, and interleukin-6 gene expressions in a dose-dependent manner. Conclusion: These results suggested that Eriobotryae folium might reduce the excessive proteolytic capacity of the gingival fibroblast during inflammation and could be developed as a new drug for periodontitis.

Introduction: In today's society, the rapid and appropriate care of the dental emergency patients is much more important. So, a retrospective study on the characteristics of emergency dental injuries and diseases will be very meaningful. Materials and Methods: This retrospective clinical study was carried by reviewing the radiographic films and emergency chart of 11,493 patients who had visited the emergency room of Hallym Sacred heart Hospital and were treated in the Department of Oral and Maxillofacial Surgery from January 2006 to December 2010. Results: The male to female ratio was 1.9:1. The highest monthly incidence was observed in May (10.4%) and June (8.9%) and the peak age distribution was the first decade (56.0%), followed by the second decade (16.0%). Trauma was the most common cause in dental emergency patients, followed in order by toothache, odontogenic infection, temporomandibular joint (TMJ) disorder and oral hemorrhage. Soft tissue injury was most prevalent in the trauma group, followed by tooth injury and facial bone fractures. In the tooth injury group, tooth fracture (56.7%) showed the highest incidence followed in order by tooth subluxation (18.2%), tooth concussion (16.9%), tooth avulsion (11.5%) and alveolar bone fractures (3.7%). In the facial bone fracture group, mandibular fractures (81.8%) showed the highest incidence followed in order by maxilla fractures (15.7%), nasal bone fractures (9.0%), zygomaticomaxillary complex fractures (5.4%), orbital bone fractures (2.5%). In mandibular bone fractures, the most common location was the symphysis (70.1%), followed in order by the mandibular angle (33.0%), mandibular condyle (22.8%) and mandibular body (13.6%). In the infection group, a submandibular space abscess (46.2%) was most common followed in order by a buccal space abscess (17.4%), canine space abscess (16.9%) and submental space abscess (12.3%). TMJ dislocation (89.3%) showed the highest incidence in the TMJ disorder group, followed by TMJ derangement (10.7%). In the other group, a range of specific symptoms due to post operation complications, trigeminal neuralgia, chemical burns and foreign body aspiration were reported.

Objectives : The purpose of this study was to analyze the influence which the professional dental hygiene education has on the knowledge and behavioral change for oral health to the students in the departments of dental hygiene. Methods : 771 students in the first grade and 646 students in the third grade who were attending the departments of dental hygiene from 12 colleges in Korea were surveyed. The self-administered questionnaires were distributed to the students in the colleges during May and asked them to answer the questions and then recovered them on the spot. The collected questionnaires were analyzed by using a SPSS/PC program and the difference of significance depending on the group of the students was tested by Chi-square test or Fisher's exact probability test. Results : In the number of eating snacks by the students during one day, 2-3 times was the highest, irrespectively of the grade. The rate of the students brushing their teeth after snack was higher in the third-grade students(34.8%) than in the first-grade students(20.8%). As the path of acquiring oral health knowledge, all of the first-grade and third-grade students replied that their school classes had impacted them the most. The rate of toothache experience was a higher tendency in third-grade students compared to the first-grade students(p=0.116). The rate of gingival bleeding experience was lower in the third-grade students than in the first-grade students. The rate of oral prophylaxis experience was higher in the third-grade students than in the first-grade students. In the smoking rate, there was lower in the third-grade students than in the first-grade students. The rate of acknowledging smoking hazard to the periodontal health was higher in the third-grade students than in the first-grade students. Conclusions : This study revealed that the third-grade students of dental hygiene departments who were majoring in dental hygiene had a higher perception of oral health than the first-grade students whose the dental hygiene education period was short.
