Objectives: The purpose of the study is to investigate the effect of oral exercise on oral health and oral health related quality of life in the elderly people. Methods: The subjects were83 elderly people including 42 elderly people of intervention group and 41 elderly people of control group. A dentist and a dental hygienist carried out the direct oral examination. The self-reported questionnaire was completed and the oral examination consisted of decayed tooth, missing tooth, filling tooth, functioning tooth, plaque index, salivary flow rate, and range of motion in mouth opening. OHIP-14 was used to assess the oral health related quality of life. For three months, oral exercise was done twice per week in the experimental group. Results: Before oral exercise, there was no significant difference between the intervention group and control group. After 3 months, there was a significant improvement in plaque reduction and range of motion in mouth opening between two groups (p<0.001, p<0.001). Oral health related quality of life was observed in the intervention group (p<0.001). Conclusions: The oral exercise using toothbrushing remarkably improved the oral health related quality of life in the elderly people.

This study analyzes through the review of literature and laws the exposure time, clinical frequency, and radiation exposure of intraoral and extraoral radiography as well as of panoramic radiography performed by dental hygienists in dental clinics, compares the dental radiology curriculums of radiological science and dental hygiene departments, and proposes the expansion of dental hygienists' radiography operations. The radiology curriculums were compared between the radiological science and dental hygiene departments of colleges. For new analysis by radiography for dental diagnosis, the exposure time, radiation absorbed dose, effective dose, and number of days of natural radiation were compared by the type of oral radiation films and radiographical techniques proposed by domestic and international studies. The exposure time of panoramic radiography is 15 seconds and it takes about two minutes for completion, whereas the exposure time of the standard radiography is 0.2~0.8 seconds and it takes 10 times longer for completion of the radiography of full mouth than the panoramic radiography. The standard radiography can cause distortions of radiation at severely curved parts of dental arch and palatopharyngeal reflex. However, panoramic radiography can be performed even for lock jaw patients, causes less inconvenience to patients and is much simpler than the standard radiography. The percentage of dental clinics where radiography is performed by dental hygienists was 92.0%, and the percentage of standard film radiography by dental hygienists was 98% whereas the percentage of panoramic radiography by dental hygienists was 92%. For the absorbed dose which is an indicator of radiation exposure, the When the effective dose which is an indicator of the danger of radiation exposure was converted to the number of days of natural radiation, it was 3.3 days for panoramic radiography, but 13.9 days for the full mouth standard radiography by bisecting angle technique which was 4.2 times longer than the panoramic radiography. There were two colleges that had a dental radiology course with two credits in the departments of radiological science. The credits for dental radiology courses in the department of dental hygiene ranged varied by college, ranging from 3 to 8; on average, the theory course was 2.2 credits and the practice course was 2.02 credits. To summarize the above results, the percentage of dental clinics where panoramic radiography is performed by dental hygienists under the guidance of dentists is high. Panoramic radiography has become an essential facility for dental clinics. It is faster than standard film radiography and less dangerous due to low radiation exposure. Panoramic radiography is a simple mechanical job that does not require training of oral radiography by radiotechnologist. Because panoramic radiography is one of major operations which must be performed at all times in dental clinics, it must be designated as intraoral technique rather than extraoral technique, or legalized for inclusion in the scope of operations of dental hygienists.

Background: The use of dental floss along with a toothbrush is a well-known oral hygiene product that effectively removes dental plaque and reduces the risk of dental caries and periodontal disease. Despite the fact that various types of floss are being used, flossing methods based on the thread type are being taught. In addition, personal preference according to the floss types has not been investigated. In this study, individual preferences according to the floss types were investigated by experiencing various types of dental floss to both floss users and non-users. In addition, the change in intention to use dental floss in the future after flossing experience of non-users was investigated. Methods: General public participated in the individual interview survey (n=419). Subjects responded to the questionnaire after using all of the thread type, Y-type, and C-type floss. All statistics were expressed frequencies and percentages for categorical variables, and the chi-squared test was used to determine the statistical significance of associations between the variables. Results: As a result of the analysis, the preference of C-type floss was highest in both floss users and non-users. The biggest reason for not using dental floss was not knowing the necessity of flossing (36.4%). In addition, both floss users and non-users responded that C-type floss was suitable for flossing in the anterior and posterior regions. The change in the positive future intention to use dental floss after flossing experience of non-users was statistically significantly associated with age. Conclusion: This result suggests that there is a need to provide education on how to use dental floss in various forms. Based on this, it will be possible to lead a change in individual's attitude for future oral health through active and continuous flossing experience.

Objectives: The purpose of this study was to verify the oral environmental change in using the natural oral cleaner containing propolis and prevention effect of oral disease. Methods: The subjects were 60 university students in Gangwon province. The groups consisted of 30 students of experimental group and 30 students of control group. The subjects were those who did not take the antipsychotic, diuretic, antihistamine, and anesthetic. The students rinsed their mouth with propolis mixture of oral cleanser for 4 weeks after receiving informed consent from October 1 to November 2, 2012. Collected saliva was measured for amount, salivary consistency, pH, plague index, gingival index, and halitosis. Results: The amount of salivary in propolis mixture of oral cleansing group remarkably increased (t=2.16, p<0.05). pH was alkaline in the group with oral cleaner containing the propolis (t=2.80, p<0.01). The bad breath remarkably decreased in the group with oral cleaner containing the propolis (t=-5.77, p<0.001). Conclusions: The use of the oral cleaner containing the propolis increased the amount of salivary and pH. The use of oral cleaner containing the propolis reduces halitosis and maintains good quality of oral hygiene.

Background: Korean dental hygienists perform various tasks under the supervision of dentists in addition to the tasks listed in the law. Many meaningful studies have been conducted to determine the actual tasks of dental hygienists, but these studies did not show common results due to the differences in research methods or designs. Hence, this study aimed to review the reported data on the tasks of dental hygienists in Korea and to clarify them based on a systematic literature review. Methods: For the literature search, the COre, Standard, and Ideal model presented by the National Library of Medicine was referenced. Seven databases were searched for literatures published in Korea, including PubMed, and Google Scholar. Of the 352 studies found using key words, titles, and abstracts, 46 were finally extracted based on the first and second exclusion criteria. After confirming the tasks of Korean dental hygienists in 46 literatures, 136 tasks were listed and calculated as appearance rate in the literature. Results: The most common tasks in 46 studies were fluoride application (67.2%), radiography (65.4%), scaling (65.4%), sealant (60.7%), patient management and counseling (56.7%), tooth-brushing education (52.2%), impression taking with alginate (50.1%), and making temporary crowns (47.9%). The most mentioned tasks of dental hygienists in public health centers were fluoride application (100%), sealant (100%), oral health education (71.4%), public oral health program evaluation (71.4%), school fluoride mouth-rinsing program (71.4%), water fluoridation (57.1%), tooth-brushing education (57.1%), school oral health programs (57.1%), and public elderly oral health programs (57.1%). Conclusion: This study showed that Korean dental hygienists had 136 tasks by reviewing 46 related studies and that the main job of Korean dental hygienists was oral disease prevention including scaling, sealant, and fluoride application.

The aim of this study was to analyze the factors related to self-reported halitosis. This study performed a questionnaire survey, targeting at 450 adults who lived in Seoul and Gyeonggi area. Main results of this study were as followings. Relationships between socio-demographic characteristics and halitosis showed no significant difference. Relationships between subjective oral health and halitosis, the groups that were treated dental prosthesis, aware of periodontal disease and dry mouth symptoms reported more halitosis (p<0.05). The group that brushed teeth less than twice a day, did not brush teeth after having a snack, and had frequent sweet treat reported more halitosis (p<0.05). The group that more experienced limitation, discomfort, discomfort reported more halitosis (p<0.05). Based on the results derived as above, the self-reported halitosis was shown to be related to periodontal disease, dry mouth, oral hygiene care and quality of life. Therefore, it is considered that preventing periodontal disease and oral dryness as well as reinforcing the oral hygiene care will contribute to prevention of halitosis and enhancement of quality of life.

In this paper, we propose a study is to prepare basic data for integrated health promotion education by preventing dry mouth and dry eyes through lifestyle management. From October 7 to 17, 2022, a total of 516 respondents who voluntarily agreed and responded through a self-written structured questionnaire were statistically analyzed for university students in their 20s across the country. As for the factor of feeling dry mouth among the living habits of the study subjects, the more smoking per day, the higher(8.41±2.041) and very high(7.75±2.927) felt dry mouth(p=.015), and the time spent using smart phones. The shorter this was, the lower(1.16±0.784) and very low(1.83±1.672) felt dry mouth(p=.022). The main factors contributing to dry mouth and dry eyes were dry eyes (odds ratio 3.651, p=.000), and high smoking(odds ratio 0.916, p=.038), and the more you use your smart phone (odds ratio 0.256, p=.004), the more you feel dry mouth. When feeling dry eyes, they felt dry mouth more(odds ratio 4.002, p=.000), and the more they exercised, the more dry eyes they felt(odds ratio 1.600, p=.009). As a result, since dry mouth and dry eyes appear as common inconveniences, it was found that lifestyle management is necessary to maintain and promote a healthy life. Therefore, it is proposed to build an integrated health platform that can improve the quality of life and implement personalized health management programs.

Background: Microstomia is defined as a condition with a small sized-mouth that results in functional impairment such as difficulty with food intake, pronunciation, and poor oral hygiene and cosmetic problems. Several treatment methods for microstomia have been proposed. None of them are universally applicable. This study aims at analyzing the cases treated at our institution critically reviewing the pertinent literature. Methods: The medical records of all microstomia patients treated in our hospital from November 2015 to April 2018 were reviewed retrospectively. Of these, all patients who received surgical treatment for microstomia were included in the study and analyzed for etiology, chief complaint, surgical method, and outcomes. The functional outcomes of mouth opening and intercommissure distance before and after the surgery were evaluated. The cosmetic results were assessed according to the patients' satisfaction. Results: Five patients with microstomia were corrected. Two cases were due to scar contracture after chemical burn, two cases derived from repeated excision of skin cancer, and one patient suffered sequela of Stevens-Johnson syndrome. The following surgical methods were applied: one full-thickness skin graft on the buccal mucosa, three buccal mucosal advancement flaps after triangular excision of the mouth corner, and one local buccal mucosal flap. Mouth opening was increased by 6.0 mm, and the intercommissure distance improved by 7.2 mm on average. Follow-up was 9.6 months (range, 5-14 months). Cosmetic assessment was as follows: two patients found the results excellent, three judged it as good. Conclusion: Microstomia has several causes. In order to achieve optimal functional recovery and aesthetic improvement it is important to precisely evaluate the etiologic factors and the severity of the impairment and to carefully choose the appropriate surgical method.
