Impact of incivility experienced by dental hygienists on organizational achievement-as a mediating effect of emotional exhaustion / 대한구강보건학회지

OBJECTIVES: Workplace incivility is experienced by dental hygienists, who perform a variety of tasks and roles in dentistry. Therefore, to enhance the performance of dental and medical institutions, it is necessary to identify dental hygienists experiencing incivility that affects the organizational performance. METHODS: Over a two-month period from May 1 to June 30, 2015, dental hygienists from 30 dental and medical institutions in Busan, the North and South Gyeongsang Provinces, Daegu, Seoul, and the Gyeonggi Province were convenience sampled. Data, from a total of 344 participants, were analyzed using the SPSS and AMOS statistical analysis software. RESULTS: Emotional exhaustion had a partial mediating effect on the relationship between patient incivility and job performance, a full mediating effect in relation to job satisfaction, and a partial mediating effect on the association with turnover intention. Meanwhile, emotional exhaustion had a full mediating effect on the relationships between superior incivility and job performance, as well as turnover intention, while a partial mediating effect in relation to job satisfaction. CONCLUSIONS: An in-depth review of interventions that can enable a mutually respectful working environment, and promote a healthy culture among dental hygienists in dental and medical institutions is needed.

The need for developing guidelines for radiation protection in dental institutions / 대한구강보건학회지

OBJECTIVES: The objectives of this study were to determine the radiation safety status of dental care institutions and to contribute to the development of guidelines for radiation protection in dental clinics in order to improve the work environment and reduce the radiation hazard for practitioners. METHODS: The subjects were selected using a convenience sampling. A total of 300 subjects participated in this study, including 150 dental hygienists from dental clinics in Gwangju Metropolitan City with radiation-related work experience and 150 dental hygienists who had participated in a seminar hosted by the Korean Dental Insurance Manager Association held on January 17, 2016. For the survey, self-entry questionnaires were used, and the collected data were analyzed by performing a frequency analysis using cross tabulation (χ2-test) and t-test, one-way analysis of variance, and multiple regression analysis. RESULTS: The awareness on radiation protection among dental hygienists showed 4.4 out of 5 points, which was high, but the practice of radiation protection was overall poor. For the necessity of developing radiation protection guidelines, 91.9% answered “Yes, it is necessary.”. CONCLUSIONS: The level of radiation protection practiced at dental healthcare centers was much lower than the awareness of it and showed that the requirement of guidelines for radiation protection was high. Therefore, institutional devices require the development and utilization of various types of radiation protection guidelines in order to mitigate radiation risks and improve the work environment.

A study on dentist and dental hygienist burnout / 대한구강보건학회지

OBJECTIVES: Dentists and dental hygienists undergo high levels of stress due to various factors and the burnout of health-care personnel is very important in the context of personal and social problems. Therefore, empirical research reflecting the social, cultural, and special circumstances of the medical environment is necessary. Here, we explore the causes and outcomes of burnout in dentists and dental hygienists and present ways to prevent burnout. METHODS: A cross-sectional research design was used to measure burnout of 141 dentists and 61 dental hygienists. A structured questionnaire containing the Maslach Burnout Inventory (MBI) was administered from May to June, 2018. Data were analyzed using SPSS 25.0, descriptive statistics, t-test, Mann-Whitney test, Kruskall-Wallis test, and multiple regression analysis. RESULTS: Each participant's MBI was measured in three aspects (emotional exhaustion, depersonalization, and personal accomplishment). The MBI scores of dentists with regards to their emotional exhaustion, depersonalization, and personal accomplishment were 24.8%, 34%, and 48.2%, respectively. Alternatively the scores of dental hygienists were 45.9%, 44.3% and 52.5%, respectively, for the same parameters. While the factors affecting the burnout of dentists and dental hygienists were different, it had a negative impact on the professional performance of both. CONCLUSIONS: According to the results of this study, Korean dentists and dental hygienists experience high levels of work-related burnouts. This can have adverse impacts on their personal health and that of their patients. Therefore, stress management is necessary in dentists and dental hygienists.

Job satisfaction level of dental staff at oral health centers for people with special needs / 대한구강보건학회지

OBJECTIVES: The purpose of this study was to investigate the job satisfaction level of the dental staff working at oral health centers for people with disabilities. METHODS: A questionnaire survey was conducted with 73 dentists and dental hygienists working at seven regional oral health centers for people with special needs and dental hospitals for people with disabilities in Seoul. The questionnaire consisted of seven questions across two subscales: general satisfaction (4 questions) and satisfaction with wage and welfare (3 questions). The internal consistency of the questionnaire items was assessed using Cronbach's alpha (0.80). The responses were analyzed using a t-test with SPSS (version 23.0). RESULTS: Of the 73 dental staff members, 50% were dentists, 64% were women, and participants' average age was 30 years. In total, 58% of the participants had up to five years of experience working with people with disabilities, 42% of them worked full-time, and each participant treated an average of 200 patients with disabilities per month. The participants reported that their salary was relatively low. Dental hygienists had higher satisfaction level than dentists in the institution's welfare work. The more full-time workers answered, the more suitable they are for their work. CONCLUSIONS: The job satisfaction level of most professionals working in oral health centers for people with disabilities was not very high but they felt rewarded by their welfare work. It was inferred that it is necessary to examine and improve institutional support aspects such as human resource support. Increasing the number of centers in the central region is also needed.

The Effects of Biofilm Care on Subgingival Bacterial Motility and Halitosis / 치위생과학회지

BACKGROUND: Oral diseases are caused by various systemic and local factors, the most closely related being the biofilm. However, the challenges involved in removing an established biofilm necessitate professional care for its removal. This study aimed to evaluate and compare the effects of professional self and professional biofilm care in healthy patients to prevent the development of periodontal diseases. METHODS: Thirty-seven patients who visited the dental clinic between September 2018 and February 2019 were included in this study. Self-biofilm care was performed by routine tooth brushing and professional biofilm care was provided using the toothpick method (TPM) or the oral prophylaxis (OP) method using a rubber cup. Subgingival bacterial motility and halitosis (levels of hydrogen sulfide, H₂2S; methyl mercaptan, CH₃SH; and di-methyl sulfide, (CH₃)₂S) were measured before, immediately after, and 5 hours after the preventive treatment in the three groups. Repeated measures analysis of variance test was performed to determine significant differences among the groups. RESULTS: TPM was effective immediately after the prevention treatment, whereas OP was more effective after 5 hours (proximal surfaces, F=16.353, p<0.001; smooth surfaces, F=66.575, p<0.001). The three components responsible for halitosis were effectively reduced by professional biofilm care immediately after the preventive treatment; however, self-biofilm care was more effective after 5 hours (H₂S, F=3.564, p=0.011; CH₃SH, F=6.657, p<0.001; (CH₃)₂S, F=21.135, p<0.001). CONCLUSION: To prevent oral diseases, it is critical to monitor the biofilm. The dental hygienist should check the oral hygiene status and the ability of the patient to administer oral care. Professional biofilm care should be provided by assessing and treating each surface of the tooth. We hope to strengthen our professional in biofilm care through continuous clinical research.

Effect of Emotional Labor on Somatization among Dental Hygienists in an Area / 치위생과학회지

BACKGROUND: We investigated somatization symptoms experienced by dental hygienists due to stress from emotional labor. Our aim was to provide basic research data that could be useful in the development of efficient stress management schemes for this occupational group. METHODS: We analyzed data collected from 208 dental hygienists working in Jeollabuk-do Province, Korea. To measure the level and intensity of emotional labor among research participants, we used the Korean Emotional Labor Questionnaire. We used the Somatization Symptom Checklist-90-Revised (SCL-90-R) to measure the level of somatization symptoms among participants. RESULTS: On analyzing the level of emotional labor and somatization symptoms according to general characteristics, participants aged 23~25 years showed high scores for stress due to emotional labor (p<0.05). Working 5 days per week, subjective health status, and organizational support and protection systems were found to correlate with the level of stress due to emotional labor (p<0.05). In the analysis of correlations between emotional labor and somatization symptoms, scoring high across all domains of emotional labor was associated with scoring high for somatization symptoms in the subdomains of emotional labor. When emotional labor and demographical variables were used as independent variables, having higher scores for emotional labor and having poor subjective health status were found to be associated with having higher levels of somatization symptoms (p<0.05). CONCLUSION: Our results showed that working at night and organizational support and protection systems were correlated with emotional labor and somatization symptoms. Measures must be taken at the organizational level to reduce emotional labor and somatization symptoms.

Determining the Relationship among Organizational Commitment, Occupational Stress, and Interpersonal Relations according to Adult Attachment Styles of Clinical Dental Hygienists / 치위생과학회지

BACKGROUND: This study aimed to identify the types of adult attachment and determine the relationship between adult attachment and job factors in dental hygienists. Ultimately, it was necessary to identify the need for a secure attachment to improve the quality of clinical dental hygienist's services. METHODS: Data of 454 clinical dental hygienists working in dental hospitals or clinics were collected. The research tools consisted of items related to the general and work characteristics of dental hygienists (9 items), adult attachment styles (36 items), organizational commitments (12 items), occupational stress (15 items), and interpersonal relations (18 items). Cronbach's α of each tool was ≥0.7. RESULTS: Most of the participants had fearful attachment styles, followed by dismissing-avoidance, security, and preoccupation. Security was the highest level of organizational commitment according to the adult attachment style, although the differences of the levels were insignificant. For occupational stress, preoccupation was the highest, followed by fearful, security, and dismissing-avoidance, and the differences were significant (p<0.001). For interpersonal relations, security was the highest, followed by preoccupation, dismissing-avoidance, and fearful in order, and the differences were significant (p<0.001). CONCLUSION: Job stress and interpersonal relation ability according to the adult attachment style of clinical dental hygienists had significant results. Thus, the development of attachment improvement programs by personal style, development of differentiated clinical education and its application, and improvements in the adult attachment styles of clinical dental hygienists would be required rather than simply presenting the needs to collectively improvement the working environment.

Effects of Critical Thinking and Communication Skills on the Problem-Solving Ability of Dental Hygiene Students / 치위생과학회지

BACKGROUND: This study aimed to investigate the effects of critical thinking and good communication skills on the problem-solving abilities of dental hygiene students. METHODS: A total of 508 dental hygiene students were convenience-sampled from 3 universities. RESULTS: The results revealed that critical thinking had the highest intellectual fairness score of 3.60, and systematicity was the lowest at 3.19. The values for communication skills were high in reaction, social adequacy, and concentration, with an average of 3.65. Problem-solving abilities were in the following order: clarification of the problem, seeking solutions, and decision making. According to general characteristics, more extroverted personalities possessed higher levels of critical thinking, communication skills, and problem-solving abilities (p<0.01). Critical thinking scores were high (p=0.016) in students who responded that peer relationship was difficult; however, their communication skills were the lowest (p<0.001). Additionally, problem-solving abilities were highest among students who reported a difficult peer relationship (p=0.001). The higher the satisfaction with dental hygiene academics, the higher the critical thinking, communication skill, and problem-solving ability (p<0.001). Critical thinking showed a high positive correlation with variables in the following order: clarification of the problem, performing the solutions, seeking solutions, decision making, and evaluation and reflection. The communication skills were also related to these variables listed above (p<0.01). With critical thinking, confidence, watchfulness, intellectual passion/curiosity, sound skepticism, objectivity, and systematicity all influenced the problem-solving ability. CONCLUSION: Communication skills were influenced by noise control, putting on the other's shoe, social tensions, and efficiency, which affected the problem-solving ability. Dental clinics require dental hygienists to have critical thinking to make analytical judgments and effective communication skills to solve human relation problems with patients and care-givers. Therefore, these skills should be developed in dental hygiene students to improve their problem-solving abilities.

Effects of Self-Efficacy and Job Stress on Organizational Commitment among Clinical Dental Hygienists / 치위생과학회지

BACKGROUND: This study aimed to provide basic data to establish a foundation for efficient operation of the organization by assessing the effects of self-efficacy and job stress (measured by self-efficacy, job demand, and job autonomy) on organizational commitment among clinical dental hygienists. METHODS: This was a cross-sectional survey study that used a self-administered questionnaire to collect data. After institutional review board approval, a survey was conducted from January to May 2017, targeting dental hygienists working in dental clinics and hospitals. The final 199 questionnaires were analyzed with PASW 18.0 for Windows (IBM Corp.). The data were analyzed using mean and/or standard deviation t-test, one-way ANOVA, and multiple regression analysis. RESULTS: The means for self-efficacy, job demand, job autonomy, and organizational commitment were 55.94±9.65, 26.55±2.29, 20.24±3.88, and 49.49±8.39, respectively. Along with self-efficacy, the other factors of organizational commitment among dental hygienists that were statistically significant included job autonomy, mean salary (2,500~2,990 thousand Korean won [KRW] and ≥3,000 thousand KRW), and employee welfare (good), which are sub-areas of the surface acting. In other words, it was found that the higher the mean salary, the better the employee welfare, the higher self-efficacy, and the higher the organizational commitment, and the explanatory power of the model was approximately 42.1%. CONCLUSION: These results suggest that the higher the self-efficacy, job autonomy, mean salary, and employee welfare, the higher the organizational commitment. In order to improve job demand among dental hygienists, it is necessary to establish an effective plan to improve job welfare, self-efficacy, and job autonomy.

Osteonecrosis of the jaw in the era of targeted therapy and immunotherapy in oncology

Osteonecrosis of the jaw (ONJ) is a well-known pathological condition in oncology derived from the use of bisphosphonates (BPs) and denosumab. Many molecular and immunological targets have been introduced for daily use in cancer treatment in recent years; consequently, new cases of ONJ have been reported in association with these drugs, especially if administered with BPs and denosumab. When the drugs are administered alone, ONJ is rarely seen. The objective of our study was to analyze the recent literature relative to the association of ONJ with these new drugs highlighting the pathogenic, clinical and therapeutic aspects. The close collaboration between maxillofacial surgeon, oncologist, dentist, and dental hygienist remains the most important aspect for the prevention, prompt recognition, and treatment of this pathology.

Study of Work-Related Musculoskeletal Pain and Health-related Quality of Life among Hospital Workers

PURPOSE: This study examined the work-related musculoskeletal pain and quality of life of hospital workers.METHODS: Self-reported questionnaires were sent to 350 hospital workers at Seoul and Gyeonggi-do, of which 341 were returned. The questionnaire had four items that covered the demographic information, areas of musculoskeletal problems, pain rating scale, and quality of life. The analysis was completed using descriptive statistic, and the differences between pain and demographic variables were identified using a chi-square test. The differences between the type of occupation and quality of life were analyzed by one-way analysis of variance and a Kruskal-Wallis test.RESULTS: The 12-month prevalence of work-related musculoskeletal pain was 86.1% of physical therapists, 86.5% of occupational therapists, 77.1% of dental hygienists, and 75.8% of nurses. A significant difference in the general and work related variables was observed between the subject with a physical burden and type of occupation. The most affected pain sites of the physical therapist included low back, hand and wrist, shoulder, and neck. The occupational therapists included the hand and wrist, shoulder, neck, but the nurses and dental hygienists reported the shoulder, back, hand and wrist. A significant difference in the quality of life was noted between the subjects in physical therapists and dental hygienists and the subjects in the nurses and occupational therapists (p=0.00).CONCLUSION: These findings show that hospital workers appear to be high risk for work-related musculoskeletal pain, and the quality of life of physical therapists and nurses was higher than that of dental hygienists and occupational therapists.

A study of the impact of dental hygienist concern on oral health care of the elderly / 대한구강보건학회지

OBJECTIVES: There is currently little research on dental hygienists' interest and need related to oral care. To perform elderly oral care effectively, dental hygienists must understand the features of aging in the elderly. The purpose of this study is to investigate how dental hygienists' interest affects oral care for the elderly.METHODS: 232 dental hygienists completed a self-reported questionnaire from March to April 2019. The questionnaires consisted of general characteristics of the subjects (6 items), elderly patient experience (11 items), and questions regarding aging (7 items). This study analyzed collected data by frequency analysis, ANOVA, Pearson correlation analysis, and multiple regression analysis.RESULTS: Correlation analysis between concern, need, and participation in elderly oral care showed a significant amount of correlation among all variables. We found that gender (P=0.022), education level (P=0.029), workplace type (P=0.002), and the proportion of future elderly patients were statistically significant (P=0.001) factors affecting the level of concern.CONCLUSIONS: The results of this study suggest that experience in treating and caring for the elderly are essential factors for raising the interest and understanding of oral health care for elderly patients. Therefore, we should consider the development of various programs to raise interest in oral health for the elderly.

A survey of the understanding of the scope of work undertaken by dental hygienists and chair-side dental assistants among dental students in Seoul / 대한구강보건학회지

OBJECTIVES: This study was conducted to investigate the awareness of the students currently attending dental colleges/schools in Seoul regarding the scope of work done by a dental hygienist (DH) and a chair-side dental assistant (DA).METHODS: A direct questionnaire survey was conducted among 950 students who currently attend dental colleges/schools in Seoul. We were able to use a total of 458 samples for final analysis after excluding inappropriate ones. The contents of this structuralized survey included the obligation of proper name badge use for dental health care personnel, the legal work scopes of a DH and a DA in accordance with the revised execution of the ‘Legal Acts on Medical Technicians’, and the inclusion/exclusion of such contents from dental colleges/schools curricula. The results were statistically analyzed via the IBM SPSS Statistics 25.0 software.RESULTS: Many subjects were aware of the difference in scope of work performed by a DH and a DA (P < 0.001), but not their legal obligation to wear appropriate name badges in accordance with the ‘Proposal for the Establishment of the Name Badge Standards for Healthcare Practitioners'. The subjects generally showed higher comprehension of the scope of work performed by a DH (74.3%) than that performed by a DA (57.7%). Without the presence of any corresponding curriculum, accurate responses tended to increase with the students' seniority. Most students (94.4%) agreed with the need to include a class that teaches the scope of work performed by a DH and a DA in their school curricula.CONCLUSIONS: We have found that education regarding ‘Name Badge Standards for Healthcare Practitioners’ and classification of a dental assistant's scope of work is lacking in the existing curriculum. Therefore, it is necessary to establish additional curriculum.

Effects of the 4C Core Competencies on Work Ability among Dental Hygienists / 치위생과학회지

BACKGROUND: This descriptive study aimed to examine the relationship between the 4C core competencies and work ability among dental hygienists.METHODS: From November 2018 to January 2019, data were collected-from 190 dental hygienists workong in dental clinics in Busan, Ulsan, and Gyeongsangnam province using structured questionnaires. For the general characteristics of the dental hygienists, frequency and percentage were calculated, and the level of the 4C core competencies and work ability of dental hygienists was calculated using means and standard deviations. A multiple regression analysis was conducted to analyze the effects of the 4C core competencies on work ability.RESULTS: The mean scores for the 4C core competency levels of the dental hygienists were as follows: communication ability 3.34, critical thinking ability 3.41, creative problem-solving 3.40, and collaborative self-efficacy 3.27. Meanwhile the mean score for work ability level was 3.65. The predictive factors influencing work ability were communication ability and cooperative self-efficacy (p<0.001), and the sub-factors of critical thinking ability that affect work ability were sound conferences (p<0.01), intellectual fairness (p<0.05), intellectual enthusiasm (p<0.05), and self-confidence (p<0.001). Finally, the sub-factors of creative problem-solving ability that affect work ability were planning and execution (p<0.01) and performance evaluation (p<0.05).CONCLUSION: The current study showed that education programs covering the core competencies of dental hygienists, rather than the existing theoretical education program, should be developed and implemented to enhance 4C core competencies that affect work ability.

Relationships between Depression, Oral Dryness, and Oral Health-Related Quality of Life among Elderly in Korea / 치위생과학회지

BACKGROUND: This study aimed to analyze correlations between depression, cognitive function, oral health state, ability to perform activities of daily living, oral dryness symptoms, and oral health-related quality of life, and determine factors influencing the latter.METHODS: This was a cross-sectional study based on questionnaires completed by 260 participants with suspected dementia, residing in South Korea. Psychiatrists, psychiatric nurses, and dental hygienists visited clinics in the participating regions for examination and questionnaire administration. General characteristics, the geriatric depression scale, ability to perform activities of daily living, cognitive function, oral health state, and oral health-related quality of life were analyzed. Independent t-tests, one-way analysis of variance (ANOVA), correlation analysis and multiple regression analysis were conducted, identifying factors affecting oral health-related quality of life. Data analysis was performed using SPSS ver. 20.0 (IBM Corp., USA), and the significance was set at p<0.05.RESULTS: Approximately 65.0% of participants were female, 63.5% were in their 70s, and 90.0% had health insurance. About 21.5%, 42.0%, and 36.5% were normal, slightly impaired, and had dementia, respectively. High cognitive impairment was associated with poor oral health. Sex, education levels, marital status, and living arrangements influenced oral health-related quality of life. According to the regression analysis, geriatric depression and oral dryness affected the Geriatric Oral Health Assessment Index scores.CONCLUSION: In conclusion, oral dryness and depression levels among elders influenced oral health-related quality of life. The results showed that to enhance elders' oral health-related quality of life, it is essential to not only improve their oral health state, but also relieve oral health problems, especially oral dryness, and take into consideration their psychological aspects.

Awareness of occupational hazards and personal protective equipment use among dental hygienists / 영남의대학술지

BACKGROUND: The aim of this study was to evaluate the awareness of occupational hazards and personal protective equipment use among dental hygienists (DHs).METHODS: A total of 271 self-administered questionnaires were obtained from 280 DHs working at dental hospitals or clinics in Daegu and Gyeongsangbuk-do, Korea.RESULTS: The occupational hazards included work involving dust (94.1%), volatile substances (86.0%), noise (97.0%), and light-curing units (96.7%). The proportion of dental hygiene tasks that participants perceived as harmful were 42.4%, 51.7%, 9.2%, and 31.4% in the same order as above. The proportion of participants who used dust-proof masks during work involving dust was 1.1%. Those who wore gas-proof masks and gloves for work using volatile substances were 0.7% and 31.2%, respectively. Participants who used goggles for work involving light-curing units were 31.0%. None of the participants used ear plugs for work involving noise. A total of 22.9% of the participants recognized the Material Safety Data Sheet, while 79.7% had never been educated about harmful work environments.CONCLUSION: When compared to exposure status and perception of occupational hazards, the level of protective equipment use was very low. Extra measures to increase DHs’ use of personal protective equipment are necessary.

Demand and willing to pay for oral hygiene service in long-term care insurance of elderly / 대한구강보건학회지

OBJECTIVES: This study was conducted to identify the demand and willingness to pay for oral hygiene services among elderly people with long-term care insurance. METHODS: Our study was a cross-sectional analysis. Subjects comprised 126 elderly individuals from long-term home-care centers. A total of 28 centers were selected through convenience sampling from among 78 centers in ○○. For analysis, semi-structured questionnaires that required about 20–30 minutes to complete were used. Analysis was performed using SPSS 23.0 software. RESULTS: The overall demand for oral hygiene services was 44.4%, and willingness to pay was 31.0%. Thirty-three people (58.9%) of elderly those who have demand for an oral hygiene service were willing to pay for the service, and 64 people (91.4%) who did not have a demand were not willing to pay for it. Among those with partial dependence on brushing, 65.6% had demand for oral hygiene services and 50.0% were willing to pay costs. Among basic livelihood beneficiaries, 69.6% were willing to pay for oral hygiene services; general subjects and relievers were less willing to pay. CONCLUSIONS: The overall demand for oral hygiene services among elderly people was 44.4%, and the willingness to pay was as low as 31.0%.

The relationship between oral health and radiation-induced mucositis among patients with head and neck cancer / 대한구강보건학회지

OBJECTIVES: This study evaluated the relationship between oral hygiene and health status and radiationinduced mucositis among patients with head and neck cancer over an 8-week period. METHODS: We recruited 40 patients with head and neck cancer scheduled to receive radiation therapy (RT), and 25 patients were included in the study. Before commencing RT, a dentist examined the patients for plaque, and determined the gingival index and pocket depth. A dental hygienist assessed the patients for radiation-induced mucositis once weekly, for 8 weeks, during RT. RESULTS: The mean patient age was 60.96 (±8.47) years, and 21 (87.5%) patients were male. Twenty patients (83.3%) had been diagnosed with squamous cell carcinoma. Patients with cancer located in the head region had more severe mucositis than those with cancer in the neck region, but this was not significant statistically (P=0.053). However, toothbrushing frequency, plaque, gingival index, and pocket depth were not related to radiation-induced mucositis. During RT, the severity of mucositis significantly worsened compared to that at baseline. CONCLUSIONS: Mucositis severity worsened during RT, but this was not related to oral hygiene and health status among patients with head and neck cancer.

Can the number of functional teeth potentially affect cognitive function? / 대한구강보건학회지

OBJECTIVES: With the growing elderly population, there is an increasing interest in the oral and general health of elderly individuals. Loss of teeth is representative of oral disease in elderly individuals and is associated with medical and dental problems. The purpose of this study was to investigate the relationship between the number of remaining functional teeth and cognitive function. METHODS: A total of 456 (111 public health centers, 261 senior centers, 84 sanatoriums) older adults (aged ≥65 years) residing in Korea were included. A mental health nurse examined the cognitive function using the Korean version of the Mini-Mental State Examination. A dentist examined the number of functional teeth and denture status through an oral examination, while a dental hygienist surveyed the subjective masticatory level using a questionnaire. RESULTS: The mean age of the participants was 79.5 years (range 65–97 years), and 76.1% of them were women. Participants with a small number of functional teeth had lower cognitive function. In these participants, the odds ratio with poor cognitive function was 2.30 times higher; it was 2.74 times higher after adjusting for age, sex, residence, education, and denture use, and was statistically significant. CONCLUSIONS: Our study suggested that the number of functional teeth was associated with cognitive function in the Korean elderly population.
