Recently, there are lots methodologies to improve the quality of research in medical and public health fields. One of them is to checking a process of research with a reporting guideline before reporting paper. Especially, reporting guideline for randomized controlled trials (RCTs) is the consolidated standards of reporting trials (CONSORT). Therefore, this review describes the latest version of the CONSORT statement, CONSORT 2010, including intent, background, and contents of this. The CONSORT statement comprises a checklist of essential items that should be included in reports of RCTs and a diagram for documenting the flow of participants through a trial. This report guideline aims at providing guidance to authors about how to improve the reporting of their trials. As consulting the CONSORT, authors could be strictly reported about research methods and results. From this review, we expect to elevate the quality of such research about dental hygiene and to establish the foundation for evidence-based dental hygiene.

Composite resins, commonly used in clinical practice, have been developed to improve aesthetics to obtain smooth surfaces. Although the restored composite resin has a smooth surface, it gradually becomes rough over time. Therefore, this study measured glossiness to evaluate the surface of various composite resins and attempted to evaluate the maintenance of glossiness of composite resins by observing surfaces that change to roughness. Specimens were produced using resin used in clinical practice: Gradia direct anterior (GA), Tetric N-Ceram (TN), Ceram.X Sphere TEC one (CX), Filtek Z350XT (FT), Estelite sigma quick (ES). After creating a smooth surface with slide glass, five locations were randomly selected to measure surface gloss, and the average was the representative value of the specimen. Roughness was applied to the specimen under water pouring at the same speed and pressure using SiC paper #2400, 1200, and 400. The gloss unit of different SiC papers was measured. To evaluate the gloss unit and gloss retention between composite resins, one-way analysis of variance and Tukey multiple comparisons test were used. As a result of the study, there was a difference in gloss unit of specimens produced under the same conditions. Although the degree differed depending on the composite resin, there was also a difference in gloss retention. Based on the findings, composite resins show differences in gloss due to their different characteristics. Ceram.X Sphere TEC one (CX) showing the lowest gloss retention and Estelite sigma quick (ES) showing the highest.
The purpose of this study was to examine the awareness of people in general about halitosis. The subjects in this study were 184 people who visited the clinical practice lab at J health college to get their teeth scaled. After a survey was conducted from May 1 to June 3, 2008, the analyzable answer sheets from 178 respondents were analyzed after four different areas were selected, which included smoking/nonsmoking, scaling experience, toothbrushing frequency and the use of oral hygiene supplies. SPSSWIN 12.0 program was utilized to make a frequency analysis and crosstabs analysis. The findings of the study were as follows: 1. Concerning subjective feelings of halitosis, 55.3 percent(99 people) of the respondents found themselves to have a moderate level of bad breath. 28.5 percent(51) deemed themselves to have a little foul breath, and 14 percent(25) didn't feel they had any bad breath. 2. As to the subjective level of halitosis, 89.8 percent(168) thought that their bad breath was a little perceived only by themselves, regardless of smoking, scaling experience, toothbrushing frequency and the use of oral hygiene supplies. 3. In regard to the cause of halitosis, 31 percent(56) cited plaque in the mouth as the cause, and 28.5 percent(51) pointed out the other causes that weren't mentioned in the questionnaire. 18.4 percent(33) cited decayed tooth, and 11.2 percent(20) pointed out gastroenteric disorder. 10.6 percent(19) viewed diabetes as the cause. 4. As to the time when they had the subjective symptom of halitosis, 114 respondents(63.7%) felt their own bad breath the most immediately after they got up 21.8 percent(39 respondents) did it when they were hungry 5.5 percent(9) did that before breakfast, and 4.5 percent(8) did that after having breakfast. 5. Regarding view of how to prevent halitosis, 52.5 percent(94) brushed their teeth frequently 21.2 percent(38) got their teeth scaled on a regular basis at a dentist's office, and 17.9 percent(32) drank water often. The above-mentioned finding seemed to suggest that the respondents weren't well aware of the fact halitosis was a sort of oral and systemic disease. Therefore the development of halitosis prevention and care programs geared toward practice lab visions were required.
Purpose: Oral hygiene, maintained through plaque control, helps prevent periodontal disease and dental caries. This study was conducted to examine the accuracy of plaque detection with an intraoral scanner(IOS) compared to images captured with an optical camera. Materials and Methods: To examine the effect of color tone, artificial tooth resin samples were stained red, blue, and green, after which images were acquired with a digital single-lens reflex (DSLR) camera and an IOS device. Stained surface ratios were then determined and compared. Additionally, the deviation rate of the IOS relative to the DSLR camera was computed for each color. In the clinical study, following plaque staining with red disclosing solution, the staining was captured by the DSLR and IOS devices, and the stained area on each image was measured. Results: The stained surface ratios did not differ significantly between DSLR and IOS images for any color group. Additionally, the deviation rate did not vary significantly across colors. In the clinical test, the stained plaque appeared slightly lighter in color, and the delineation of the stained areas less distinct, on the IOS compared to the DSLR images. However, the stained surface ratio was significantly higher in the IOS than in the DSLR group. Conclusion: When employing IOS with dental plaque staining, the impact of color was minimal, suggesting that the traditional red stain remains suitable for plaque detection. IOS images appeared relatively blurred and enlarged relative to the true state of the teeth, due to inferior sharpness compared to camera images.
The purpose of the present study was to examine dental hygienists' perception of the current national practical examination. This research was performed using 199 self-reported surveys answered by professors of dental hygiene studies and clinical dental hygienist. Frequency analysis, chi-square tests, and analysis of variance were performed by using IBM SPSS Statistics ver. 20.0. The results revealed that many of the respondents consider the current national practical examination to be neutral. They did not think that the current national practical examination questions are useful for assessing occupation-centric integrated clinical practice ability and counseling techniques for patient intervention. The professors of dental hygiene studies believed that among the research tasks required as mentioned in the national practical examination questions, dental polishing and tooth brushing education are of paramount importance, whereas clinical dental hygienists believed that ultrasonic scaling is the most important (p<0.05). Most of the professors of dental hygiene studies reported that they conducted skills education for dental polishing and tooth brushing education, while most of the clinical dental hygienists reported that tasks actually performed in the clinic included impression taking, model fabrication, ultrasonic scaling, and explaining treatment precautions (p<0.05). Therefore, these tasks can be effectively carried out with the improvement of the national dental hygienist practical examination.
The purpose of this study was to examine the influence of the communication competence and empathy abilities of dental hygiene students on their interpersonal relationship abilities. The subjects in this study were 578 students who majored in dental hygiene at five randomly selected colleges. Out of the colleges, three were located in North Chungcheong province, and one was located in the city of Daejeon. The other one was located in South Gyeongsang province. Data were gathered using structured questionnaires from April 1 to May 7, 2013. The major findings of the study were as follows: 1. The respondents got a mean of $3.23{\pm}0.49$, $85.80{\pm}10.12$ and $83.27{\pm}8.37$ in interpersonal relationship abilities, communication competence and empathy abilities respectively. 2. As for communication competence, empathy abilities and interpersonal relationship abilities by general characteristics, there were statistically significant differences according to age, academic year, clinical practice experience and satisfaction with major. 3. The relationship of communication competence and empathy abilities to interpersonal relationship abilities was analyzed, and interpersonal relationship abilities were found to have a strong significant positive correlation to communication competence, empathy abilities and the subfactors of the two. 4. As a result of analyzing which variables affected interpersonal relationship abilities, it's found that interpersonal relationship abilities were under the influence of age, clinical practice experience, communication competence, empathy abilities. These variables made a 57.2% prediction of interpersonal relationship abilities. The above-mentioned findings suggest that communication competence and empathy abilities exerted an influence on interpersonal relationship abilities. Therefore curriculums and educational programs should be developed in consideration of these variables to ensure the stable college lives and successful relationship building of dental hygiene students who are on the way to adulthood and will serve as health care personnels in the future.
Background: The purpose of this systematic review was to investigate the effects of topical fluoride gel application on dental caries prevention in the permanent teeth of children and adolescents. Methods: We searched the EMBASE, PubMed, and Cochrane Library databases for randomized controlled trials (RCTs) assessing the effects of self-applied or professionally applied topical fluoride gels in patients <18 years of age; the search was completed on April 1, 2018. All included trials involved an experimental group (fluoride gel application) and a control group (placebo or no treatment). The outcome measures were the D(M)FS and D(M)FT indices, which were compared between the two groups. Review Manager software was used for quantitative synthesis of the final selected articles, and a forest plot was generated via a meta-analysis conducted using a random effects model. Results: The results showed that the D(M)FS and D(M)FT indices were lower in the fluoride application group than in the control group, thus indicating that fluoride gel application was effective in dental caries prevention. We also performed a subgroup analysis to determine whether the effects of fluoride application differed if patients received oral prophylaxis (self or professional) before fluoride gel application. Therefore, the two groups showed slightly larger differences when studies without oral prophylaxis before fluoride gel application were considered; however, the difference was not statistically significant. Conclusion: These findings should be utilized to raise awareness about the caries-prevention effects of topical fluoride application among patients and guardians. Further RCTs should evaluate the effects of fluoride application with or without preceding oral prophylaxis, and appropriate fluoride application guidelines should be developed to maximize the effects of fluoride application in clinical practice.
This study was based on the experience of dental hygienists' role conflict, and attempted to grasp the nature of the dental hygienist role conflict factor, constituent factor and coping. Giorgi's phenomenological method was used to analyze data collected through in-depth interviews with nine dental hygienists working in a dental clinic. The analysis revealed three central meanings: task scope, role conflicts, and role conflict management style and limitations. In the first category, task scope, the range of the legal scope, and the duties performed by the dental hygienist differed slightly. The second category included role conflict due to interpersonal relationship, work, work environment, competence, and identity as a professional because of role conflict. The third category included the role conflict management style and limitations. Dental hygienists tried to solve the role conflict situation through various efforts. In the face of the reality that the conflict is not solved despite such efforts, the dental hygienists felt the limitation and chose to leave. Dental hygienists are dissatisfied with their roles because of confusion regarding professional values and lack of awareness of the professional workforce due to differences between legal scope and actual practice. Based on the results of this study, it is necessary to develop a tool to quantitatively measure the level of role conflict in dental hygienists and to conduct follow-up studies on the effects of coping strategies by role conflict situations.
The water supplied from dental unit water systems (DUWS) in dentistry may be heavily contaminated with bacteria and thus may be a potential source of infection for both practice staff and patients. The aim of this study was to evaluate the level of heterotrophic bacteria and to confirm the presence of opportunistic pathogens from DUWS in student clinical simulation laboratory of college of dentistry. Water samples were collected from 36 ultrasonic scalers in student clinical simulation laboratory. The levels of heterotrophic bacteria in water samples were quantified by counting colony forming units (CFUs) on R2A agar media. In addition, opportunistic pathogens were detected by using the polymerase chain reaction (PCR) method. The mean CFUs were 16,095 CFU/ml for water samples and all of water samples exceeded current American Dental Association recommendations of 200 CFU/ml. Pseudomonas species and non-tuberculous Mycobacterium species were detected in the one sample and two samples, respectively, among the 36 water samples by the PCR with specific primers for these bacteria. Our study indicated that DUWS in student clinical simulation laboratory can cause potential infection in students and participants. This study suggested the dental unit water line management and wearing personal protective equipment in student clinical simulation laboratory will be needed to reduce bacterial contamination.
This study conducted a survey of 265 dental hygienists working in Seoul and Gyeonggi Province from January 10 to February 28, 2021 to understand the ethical values and professional occupational characteristics of clinical dental hygienists. The difference in ethical values and professional occupational perception between subjects was post-tested using SPSS WIN 20.0 program and Scheffe test using independent sample T-test and one-way ANOVA. According to the results of the study, ethical thinking in ethical values was statistically significant in dental hospitals with higher final education, more work experience, and ethical work experience (p<0.05). The higher the age, the higher the final education, the more ethical education experience at university, the higher the sense of mission, the fewer working days, the more satisfying the job, the higher the organizational compliance with professional organizations and public service (p<0.05). The results of this study confirm the necessity of regular ethics education such as continuing education for dental hygienists, and are expected to be used as basic data to maintain ethical values and professionalism in clinical practice.
