DENTAL FEAR AND ANXIETY OF JUVENILES IN SOME AREAS OF GYEONGGI PROVINCE

The objective of this study is to measure the fear and anxiety levels of some middle school students in Gyeonggi Province, to analyze the relevant factors, to seek how to alleviate such fear and anxiety and thus enable to make a comfortable and efficient oral management. Six hundred twenty two middle school students in Gyeonggi Province participated in the survey, which used the data of 614 respondents, i.e. 337 males and 277 females. A frequency analysis was conducted to determine the distribution of answers for each question, a crosstabulation analysis was performed to verify the gender differences in answer and an Mann-whitney U test was used to compare fear scores. According to the results patients feared even in unexpected circumstances. In addition, they feared when receiving direct treatment. In terms of gender, female students showed higher levels of fear than male ones (p

Dental fear & anxiety and dental pain in children and adolescents; a systemic review

Background There are few previous studies investigating the relationship of dental fear and anxiety (DFA) with dental pain among children and adolescents. To address this issue, we examined the literature published between November 1873 and May 2015 to evaluate the prevalence of DFA and dental pain among children and adolescents, and their relationships with age and sex. Methods We performed a broad search of the PubMed database using 3 combinations of the search terms dental fear, anxiety, and dental pain and prevalence. A large proportion of the identified articles could not be used for the review due to inadequate end points or measures, or because of poor study design. Thirty-two papers of acceptable quality were identified and reviewed. Results We found that the prevalence of DFA was estimated to be 10%, with a decrease in prevalence with age. It was more frequently seen in girls, and was related to dental pain. Conclusions We concluded that dental fear, anxiety, and pain are common, and several psychological factors are associated with their development. In order to better understand these relationships, further clinical evaluations and studies are required.

Dental Fear and the associated Factors of some Middle School Students in Cheongju-City

This study aims to examine the level of fear and the influential factors affecting their dental fear and to utilize the result as the basic materials in the dental management. The subjects were the students from a middle school located in Cheongju-City. The school was selected by convenient sampling and self-answered questionnaire was filled in by the students for a week from December 19th 2011. The survey result showed that 77 male students and 169 female students(total 246 students) answered `yes` to the question `Have you ever felt fear when you visited a dentist?` among 475 students who had visited a dentist in the past. The distribution of responses in each category of fear was examined by frequency analysis. The study results showed significant difference in the item of `causing irritation during the dental treatments` between male students and female students (p

Use of three-dimensional computed tomography images in dental care of children and adolescents in Korea

Advances in computed tomography (CT) technology - from traditional CT to cone beam (CB) CT - have benefitted both the dentists and their young patients. We therefore wanted to determine the prevalence of CBCT use in pediatric dentistry in Korea. Our first approach was to conduct an institutional survey to evaluate the use of CBCT for diagnosing and evaluating dental problems in pediatric patients. Our second approach was to review any articles published during 2002-2011 in the Journal of the Korean Academy of Pediatric Dentistry that described clinical use of CBCT. The journal articles surveyed indicated that there were three areas in which CBCT was most useful. The most prevalent use was for diagnosis and monitoring of the growth of cystomas and other tumors in the mouth. The second most common use of CBCT was localization of impacted teeth and evaluation of their relations with adjacent teeth. The third use was to observe supernumerary teeth and evaluate their relations with the roots of adjacent teeth. Compared with traditional CT, CBCT has shorter acquisition times and causes less radiation exposure to the patient. There are fewer side effects with CBCT because its accuracy allows minimally invasive treatment for such problems as impacted and supernumerary teeth.

Restoration of Strip Crown with a Resin-Bonded Composite Cement in Early Childhood Caries

Background. Early childhood caries is a widely prevalent disease throughout the world. It is necessary to treat this condition in early childhood; however, child behavior management may be particularly challenging during treatment. To overcome this challenge, we used Carigel to remove caries and RelyX Unicem resin cement for strip crown restoration. It not only has the desired aesthetic effect but is also more effective for primary teeth, which are used for a shorter period than permanent teeth are. Case Presentation. We report a case of three pediatric patients with early childhood caries, in whom caries was removed by using Carigel to avoid the risk of pulpal exposure associated with high-speed handpieces. Subsequently, aesthetic restoration was performed using strip crown with RelyX Unicem self-adhesive resin cement. Conclusion. RelyX Unicem has the following advantages: (1) not requiring have any special skills for the dentist for performing the procedure, (2) decreased occurrence of bubbles during injection of the cement, and (3) overall short duration of the procedure. Thus, it is appropriate for the treatment of pediatric patients whose behavior is difficult to manage. However, further studies are required in order to establish the use of RelyX Unicem as a stable restorative material in early childhood caries.

Caries Prevalence in Korean Children and Adolescents from 2000 to 2012

OBJECTIVES National oral health data is required to assess a populations oral health needs, monitor oral health, plan effective intervention community programs and health policies, and evaluate progress toward health objectives. The study aimed to estimate the prevalence, severity, and inequality in dental caries distribution among Korean young people. STUDY DESIGN Trained, calibrated examiners at the Korea Ministry of Health & Welfare conducted epidemiological surveys in 2000, 2006, and 2012 during which dental caries were assessed according to World Health Organization (WHO) diagnostic criteria. Decayed, missing, and filled surface and tooth (DMFS/DMFT) indices were estimated. RESULTS DMFT indices decreased in all regions between 2000 and 2012, with values of 3.3, 2.2, and 1.8 for 12-year-old children in 2000, 2006, and 2012, respectively. The prevalence of caries was higher among female versus male subjects and in rural versus urban areas. CONCLUSIONS Despite the observed decrease in caries experience indicators in Korea, the caries prevalence remains considerably higher than that in European countries and than the targets set by WHO within the Health21 policy framework. Therefore, Korea apparently retains further potential for caries reduction. Community-based oral disease prevention programs are urgently needed to promote oral health.

Relationship between Oral Health Care and Happiness in Dental Hospital Patients

Background/Objectives: This study is to suggest the oral health promotion plan for the happy life by grasping the close relation between oral health care and happiness in dental hospital patients. Methods/Statistical analysis: The subjects of this study were selected as patients who came to some dental hospitals in Jeollabuk-do, Korea. The subjects were selected as the convenience sampling method and the purpose of the study was explained to the patient. Self-administered questionnaires were administered to subjects voluntarily participating in the study. The responses to the questionnaires were 359 respondents, excluding 19 who responded unfairly to the 378respondents. Findings: Overall happiness was 3.55 points. Among the items of euphoria, the feeling of happiness felt at home was the highest at 4.17 points. Secondly, the feeling of happiness felt when social life was good was 3.89 points. The next was the feeling of happiness when feeling healthy, and the feeling of happiness when feeling economical.The relationship between oral health care and overall happiness is as follows. Significant variables were the number of toothbrushes per day and oral health education. The overall happiness was higher when the number of brushings per day was more than 3 times. Overall oral well-being was high when they received oral health education. The explanatory power of the variables was 52.1.The overall happiness was higher with more intake of clean food and protection food, and the explanatory power of the variable was 55.0.Overall happiness was higher with more intake of Clean food and Protection food, and the explanatory power of the variable was 55.0. Improvements/Applications:Oral health education should be actively pursued so that the proper method and frequency of tooth brushing of Dental Hospital Patients, and the use of oral hygiene products.

Korean National Oral Health Survey Data on the Symmetry of Primary Dentition Surface Caries

OBJECTIVES This study evaluated the intraoral symmetry of dental caries in primary teeth as part of a study of caries patterns in primary dentition. STUDY DESIGN The data for 4,800 5-year-old and 4,379 8-year-old children in this study were from the 2012 Korean national oral health survey. Pearson correlation coefficients of the decayed and filled surface (dfs) values ranged from 0.436 (lower primary canines) to 0.835 (upper primary central incisors) for the right and left primary teeth and from 0.084 (right primary central incisor) to 0.457 (left primary second molar) for the upper and lower primary dentition (P< 0.01). RESULTS The upper and lower dfs values differed significantly (P< 0.05) when the right and left primary second molars were excluded. The left or right primary data without caries ranged from 56.4% (lower of first and second primary molars) to 99.7% (lower primary central incisors). The bilateral caries among cases with one or more in the right or left primary teeth ranged from 25.0% (lower lateral primary incisor) to 72.7% (upper primary central incisors). CONCLUSIONS These results suggested that dental caries in primary teeth show bilateral symmetry and differences in the degree of symmetry according to the teeth set or surface set of the homologous teeth.

Affecting the community periodontal index of korean elderly

This study was conducted to obtain basic data necessary for developing an oral health promotion program and improve the quality of life of senior citizens using elderly facilities. Towards this end, the study analyzed factors that have an impact on their community periodontal index (CPI). The elderly population, using an elderly facility located in Jeollabuk-do, was selected for convenience sampling. Of the 430 respondents who received the questionnaire, 15 were excluded for being unreliable and 415 were selected as subjects for the final analysis. The CPI was high when the subjects had no family living together with them. The CPI was high when the subjects had no monthly income. By age, those aged 80 or over had the highest CPI. Community Periodontal Index 3 was the highest with 181. There were 114 of the Community Periodontal Index 4, 94 of the Community Periodontal Index 2, and 26 of the Community Periodontal Index 0–1. Demographical characteristics that impact the CPI included gender, living with family, monthly income and age. In other words, more women than men, those living away from family, those with no monthly income and older individuals had high CPI scores, and the explanatory power of the variables was 17.6. Oral health symptoms included food impaction, bleeding, dry mouth and pain in teeth. Those with food impaction, bleeding, dry mouth and pain in teeth had high CPI scores. The explanatory power of the variables was 42.7. It may be concluded that systematic oral health education should be provided to elderly individuals to improve their oral health and enhance the quality of their lives.

The relationship between subjective oral health and dental fear in Korean adolescents

Background This study is aimed to evaluate the level of fear and to reduce the overall fear, thereby enabling patients to receive treatment via timely visits. Methods In a survey conducted by 460 South Korean middle school students, we used 453 data that faithfully responded to the survey. Multiple regression analysis was conducted to investigate the factors influencing subjective oral health and dental fear. The significance level used for statistical significance was α = 0.05. Results The level of fear was higher for upper grade, female students. The factors affecting dental fear were higher for gingival bleeding and dental pain. Regarding factors for dental fear affecting subjective oral health, lower fear of puncture needle and tooth removal tool resulted in higher subjective oral health. Conclusion The study found that adolescents had higher fear of dental care when they had gingival bleeding and tooth pain. Gingival bleeding is a symptom of early gingival disease and dental pain is likely due to advanced dental caries. These results suggested that it is necessary to have a program to reduce dental fear and anxiety as well as a program to prevent dental diseases through regular periodic screening and education.
