Objectives: The purpose of this study was to examine the influence of resilience on academic stress in dental hygiene students focused on the mediating effects of self-esteem. Methods: The subjects in this study were 208 selected dental hygiene students in colleges located in Y region of U city. A self-administered survey was conducted by 215 students from May 1 to 15, 2016. The study instruments included resilience, academic stress, and self-esteem. Results: The dental hygiene students got a mean of 4.40 in resilience. Among the subfactors of resilience, they got 4.42 in personal usefulness and 4.38 in self-receptivity. They got a mean of 3.29 in self-esteem and 2.76 in academic stress. Resilience was positively correlated with self-esteem (4=0.55, p<0.01) and negatively with academic stress (r=-0.28, p<0.01). Personal usefulness and usefulness of oneself had a positive correlation with self-esteem (r=0.51, 0.52, p<0.01) and had a negative correlation with academic stress (r=-0.25, -0.28, p<0.01). Self-esteem was negatively correlated with academic stress (r=-0.32, p<0.01). As for the mediating effects of self-esteem on the relationship between resilience and academic stress, self-esteem had perfect mediating effects on the relationship between the two. Conclusions: The results suggested that the self-esteem of the dental hygiene students played an important mediating role in the relationship between resilience and academic stress.

Lidocaine is the most commonly used local anesthetic (LA) agent in various dental as well as oral and maxillofacial procedures. Although rare, adverse effects and allergic reactions to lidocaine have been reported. In patients with suspected allergy to LA or a history of such reaction, careful history-taking and allergy testing should be performed to choose an alternative LA agent to avoid any adverse effects. Here, we present two cases of delayed hypersensitivity reaction to lidocaine, wherein the patients presented with erythema, edema, and itching. Intradermal testing confirmed allergic reaction to lidocaine, and the patients underwent successful dental treatment using an alternative LA agent. This report highlights the importance of allergy testing prior to LA use considering the serious consequences of allergy to these agents and describes the management of such patients using an alternative LA agent.

Purpose: The main purposes of this study are to describe the organization effectiveness and to investigate the effects of dental technicians' work ethic on job satisfaction, organization citizen's action, and organizational commitment. Methods: A total of 300 dental technicians working at dental laboratories in the Daegu area were randomly selected and surveyed, 298 of them were used for the statistical analysis. Results: The work ethic sub-items, such as industry, work centrality, morality, time save, independence, and relation with co-worker are independent variables. The organization effectiveness subi-items, such as job satisfaction, organization citizen's action, and organizational commitment are dependent variables. Sociodemographic variables are used for control variables. Findings are as follows: First, in terms of dental technicians' work ethic, the level of relation with coworker was the highest, and work centrality was the lowest. Second, in terms of dental technicians' organization effectiveness, the level of citizen's organizational action was the highest followed by organizational commitment and job satisfaction in order. Third, the effects of industry, work centrality, time save, relation with coworker, and morality showed statistically significant relationships with organizational effectiveness. Fourth, the effects of industry, work centrality, time save, relation with co-worker, and morality statistically significant relationships with job satisfaction. Fifth, in terms of organization citizen's action, the effects of industry, work centrality, and time save were statistically significant. Sixth, work centrality, time save, relation with coworker, and independence were statistically significant with organizational commitment. Conclusion: Some policy implications for the improvement of organizational effectiveness are introduced and discussed. Dental technicians are required to have vocation and work ethic for themselves and the organization, and by doing so, they may contribute to the improvement of national oral health. Policies and educational programs, which can support them may be necessary.

Objectives: The aim of this study is to investigate the mechanical properties and antibacterial effects on Streptococcus mutans of composite resins containing phytoncide. Methods: Phytoncide was mixed with commercial composite resins at 0 (control), 1.25, 2.5, 3.75, and 5.0 weight percentage (wt%). Mechanical properties related to composite resins such as surface hardness, depth of cure, and flexural strength were measured. Antibacterial effects of composite resins were analyzed by using Streptococcus mutans (ATCC 25175). The results were analyzed by one-way analysis of variance followed by Tukey's test (p<0.05). Results: Composite resins that contain low wt% of phytoncide demonstrated no significant difference in surface hardness, depth of cure, and flexural strength (p>0.05). However, composite resins that contain high wt% of phytoncide had significantly decreased mechanical properties (p<0.05). In terms of antibacterial effects, composite resins containing phytoncide inhibited the growth of S. mutans. Conclusions: Our findings suggest that novel composite resins containing phytoncide have effective antibacterial properties while maintaining the originally important mechanical features of composite resins.

Patients with severe gag reflex (SGR) have difficulty getting the treatment they require in local clinics, and many tend to postpone the start of their treatment. To address this problem, dentists have used behavioral techniques and/or pharmacological techniques for treatment. Among the pharmacological methods available, propofol IV sedation is preferred over general anesthesia because it is a simpler procedure. Propofol in combination with remifentanil is characterized by stable sedative effects and quick recovery, leading to a deep sedation. Remifentanil acts to reduce the pain caused by lipid-soluble propofol on injection. The synergistic effects of propofol-remifentanil include reduction in the total amount of drug required to achieve a desired sedation level and anti-emetic effects. In this case report, we outline how the use of propofol-remifentanil IV sedation enabled us to successfully complete a wide range of dental treatments in a patient with SGR.

The use of dentifries in toothbrushing is to aid removal of dental plaque and contribute to good oral hygiene. Therefore, it is important to record the quantity of dental plaque present after toothbrushing. This report concerns with the plaque removal of toothbrushing in a group of dental students who used dentifrices 'X' 'Y' and 'Z' marketed in Korea. And the cleansing effect was examined in accordance with Simplified Oral Hygiene Index. The Following conclusion was obtained. The dentifrices 'X' 'Y' and 'Z' were effective on the removal of dental plaque in the degree of -0.66±0.21, 0.70±0.24 and 0.84±0.19 plaque Index. The differences in the value of plaque Index between the dentifrices 'X', 'Z' and 'Y', 'Z' were significant statistically. The dentifrice 'Z' had the most intensive effects above all.
