Objectives: The aim of this study was to investigate the essential services, importance, interval of examinations, and role of dental hygienists in children's family dentistry program. Methods: A total of 124 participants completed a self-administered questionnaire. The data were analyzed using independent t-test, and ANOVA, and Pearson correlation analysis. Results: All participants stated that oral examination and panoramic radiography are required; children should be educated about brushing, use of oral products, and regular check-ups; and preventive treatments such as molar sealants and prophylaxis should be offered. They stated that light-curing resins and glass ionomer fillings should be offered in treatment services. They stated that examination intervals should be shorter for education and prevention rather than treatment. Dental hygiene students were more likely than dentists and dental hygienists to say that the program was more important. There was a correlation between oral examinations and education and treatment, and between essential services and their importance. Conclusions: Services considered essential and important should be provided first, education and prevention should be provided more frequently than treatment, and their importance should be emphasized not only to dental hygiene students but also to dental hygienists and dentists who are the main providers of services.

Purpose: To investigate the differences in the colon microbiota composition of Hirschsprung's disease (HSCR) patients with and without a history of postoperative Hirschsprung's associated enterocolitis (HAEC). Methods: Colon tissue microbiota was characterized by bacterial deoxyribonucleic acid (DNA) extraction and 16S rDNA sequencing for taxonomic classification and comparison. Results: The sequence diversity richness within samples was significantly higher in samples from patients with a history of postoperative HAEC. We observed an increased relative abundance of the phyla Bacteroidetes, Firmicutes and Cyanobacteria in HAEC patients and Fusobacteria, Actinobacteria and Proteobacteria in HSCR patients and, an increased relative abundance of the genera Dolosigranulum, Roseouria and Streptococcus in HAEC patients and Propionibacterium and Delftia in HSCR patients. Conclusion: Our findings provide evidence that the colon tissue microbiota composition is different in HSCR patients with and without postoperative HAEC.

Objective: To determine and compare the frequency distribution of various arch shapes in ethnic Malays and Malaysian Aborigines in Peninsular Malaysia and to investigate the morphological differences of arch form between these two ethnic groups. Methods: We examined 120 ethnic Malay study models (60 maxillary, 60 mandibular) and 129 Malaysian Aboriginal study models (66 maxillary, 63 mandibular). We marked 18 buccal tips and incisor line angles on each model, and digitized them using 2-dimensional coordinate system. Dental arches were classified as square, ovoid, or tapered by printing the scanned images and superimposing Orthoform arch templates on them. Results: The most common maxillary arch shape in both ethnic groups was ovoid, as was the most common mandibular arch shape among ethnic Malay females. The rarest arch shape was square. Chi-square tests, indicated that only the distribution of the mandibular arch shape was significantly different between groups (p = 0.040). However, when compared using independent t-tests, there was no difference in the mean value of arch width between groups. Arch shape distribution was not different between genders of either ethnic group, except for the mandibular arch of ethnic Malays. Conclusions: Ethnic Malays and Malaysian Aborigines have similar dental arch dimensions and shapes.

Early childhood caries prevalence has increased significantly in children ages 2~5 years. ECC disproportionately affects lower socioeconomic and minority groups, is a predictor for future decay, but is preventable and manageable. Caries risk assessment systematically derives a patient's caries risk and is important during an infant oral health visit beginning at age 1. Information obtained through a risk assessment can guide a disease management care path tailored to an individual's age and risk to effectively treat and manage one's caries disease process.

The purpose of this study was to provide the basic data for preventing dental caries, and maintaining and enhancing oral health. The subjects of this study were 138 male and female students who were in the 6th grade of elementary schools in Gimpo city. This study investigated the number of decayed tooth and the factors related to the number of decayed tooth, by using the results of questionnaire and oral health survey over such subjects. So, this study obtained the following conclusions. 1. For the number of decayed tooth, 'nothing(D = 0)' was the highest as 37.7%, and 'from two to three' was 23.9%, 'more than four' was 21%, and 'one' was 17.4% in order. 2. For the frequency of visiting dental clinics within the last one year, 'one to two times' was the highest as 52.2%, and the children who have not visited dental clinics even one time during one year were 23.9%. 3. For average daily tooth brushing frequency, 'two times' was the highest as 71.7%. For the use of oral health devices besides toothbrushes, 'I don't use' was the highest as 54.3%. For the experience of sealant and fluoride application, 'nothing' was the highest as 86.9% and 71.3% respectively. For the recognition on the use of fluoride dentifrice, 'I don't know' was the highest as 66.9%. 4. The socio-demographic factors related to the number of decayed tooth were mother's age, mother's background, mother's employment, and after-school fosterer(p > 0.05). 5. The oral health care factors related to the number of decayed tooth were average daily tooth brushing frequency, the use of oral health devices besides toothbrushes, and the experience of fluoride application.(p > 0.05) 6. The snack intake factors related to the number of decayed tooth were tooth care foods intake frequency and decaying foods intake frequency(p > 0.05). 7. The oral health belief item related to the number of decayed tooth was susceptibility(p > 0.05). 8. According to the results of regression analysis, the less mother was employed, the more the average daily tooth brushing frequency was, the more the tooth care foods intake frequency was, the less the decaying foods intake frequency was, and the higher susceptibility was, the lower the number of decayed tooth. 9. In order to prevent and cure early the dental caries which occur frequently in elementary school students, the establishment of oral health centers within schools should be expanded to promote tooth brushing instruction, fluoride solution rinsing, diet control, periodic oral examination.

Purpose: Recently, there has been a worldwide increase in the prevalence of food allergies in children and it may cause nutritional imbalance and poor quality of life for growing children due to dietary restrictions. This study was conducted to quantitatively measure the life burden and related factors of mothers who are the primary caretakers of food-allergic children. Moreover, we generated data for use as a scientific basis for the development of a disease management program to reduce the burden on life from raising food-allergic children. Methods: Mothers of 2,005 children aged 2 years or older and enrolled in Seoul Metropolitan Atopy Free Schools in 2016 who have had diagnosis of food allergy in their lifetime were surveyed. The burden on life of parents with food-allergic children was measured using 17 questions from the Food Allergy Quality of Life-Parental Burden (FAQL-PB) questionnaire, and subjects were asked to respond with a scale of 1 ~ 7. Results: We analyzed the effects of sociodemographic factors of parents and children and the accompanying allergic disease factors on the lives of parents. The number of restricted food items due to food allergy of a child and accompanying diagnosis of atopic dermatitis had a positive (+) effect on the life burden of the parents. Conclusion: Accurate oral food challenge for food allergies should be administered to prevent excessive restriction of food intake. Moreover, efforts should be taken to prevent morbidity accompanying food allergy and relieve symptoms of asthma, allergic rhinitis and atopic dermatitis.

The present study seeks to find the effect of oral health status that parents recognized, oral health habit and food intake on existence of decalcified teeth and decayed teeth. Participants were 293 infants aged 18-24 months who visited C dental clinic in Kyungki province between January and December 2010. Questionnaires and oral exam results were used and statistically analyzed by the SPSS program. Fisher's Exact and chi-square test were used to analyze the data. The 18-20 month-old age group had the highest rate of decalcified teeth with 36.4% while the 23-24 month-old age group had the highest rate of decayed teeth with 37.0%. Bottle feeding showed correlation with decalcified teeth, and decayed teeth. Parents were able to recognize decayed teeth and decalcified teeth. Group 2 food(soda/soft drinks/sugared fruit juice) was related to decalcified teeth and decayed teeth(p<.001). Group 4 food (cake/cookies/doughnut/dried fruit/banana) and group 5food(caramel/candy/chocolate bar) were both related to decalcified teeth(p<.001). As the result of dental examination, dental treatment was highly needed for the 21-22 month-old age group(89.3%), and preventive treatment and plaque control were highly needed for the 18-20 month-old age group(94.5%). The results concluded that 18-24 months was the critical period for children's oral health, therefore organized oral health education for parents is necessary.

Objectives : The aim of our study was to investigate association of norepinephrine transporter gene (SLC6A2) polymorphism and side effects of osmotic-release oral system methylphenidate (OROS MPH) in children with attention-deficit hyperactivity disorder (ADHD). Methods : We recruited drug naive children with ADHD (N=97). We administered OROS MPH by tolerable dosage. At week 8 of treatment, parents completed the Barkley's side effect rating scale. We analyzed two SLC6A2 single nucleotide polymorphisms (SNPs), rs192303 and rs3785143, with blood of subjects. We compared the frequency and severity of each side effect among SLC6A2 genotypes of 2 SNPs. Results : In the analysis of frequency of each side effect, irritability differed according to rs192303 and rs3785143 genotype. In comparisons of severity, talking less and disinterest differed according to rs192303 genotype. In the case of rs3785143, severities of disinterest and irritability were involved with genotype. Conclusion : Side effects of OROS MPH showed an association with SLC6A2 genotype.

The objective of this study was to investigate trends in ankyloglossia and its surgical treatment among pediatric patients in South Korea from 2011 to 2020. Data from Health Insurance Review and Assessment Service (HIRA)'s Healthcare Bigdata Hub were used for analysis of the ankyloglossia diagnosis rate and frenum surgery rate. Considering annual population change, crude rates per 100,000 were calculated and analyzed. To investigate other factors of frenum surgery incidence besides gender and age, pediatric patient sample data from HIRA were used. The diagnosis rate of ankyloglossia increased from 204.4 in 2011 to 356.6 per 100,000 people in 2020, while the frenum surgery rate increased from 26.8 to 34.3 per 100,000 people. Males were more likely to receive frenum surgery than females. Surgeries were more likely to be done at a hospital instead of a clinic or a general hospital. In the age group of 0 - 4 years, the largest number of frenum surgeries were performed in pediatrics, and in the age group of 5 - 9 years, the largest number of surgeries were conducted in pediatric dentistry. In the older age groups, the largest proportion of frenum surgeries were performed in the departments of conservative dentistry and oral and maxillofacial surgery. The diagnosis of ankyloglossia and the operation of frenum surgery among South Korean children increased during the last decade. Since the function of the tongue can affect maxillofacial development in many aspects, pediatric dentists should pay more attention to the functional management of intraoral soft tissue in growing children.

Purpose: In this study, we aimed to develop dental charts for Turkish children and young adults of both genders within the age group of 4.5-22.5 years according to tooth mineralization and eruption in a format similar to that proposed by AlQahtani et al. Materials and Methods: In total, 753 digital panoramic radiographs from 350 males and 403 females were assessed. The permanent teeth were evaluated according to the classification system described by Demirjian et al. The eruption stage was assessed with Bengston's system, which was modified by AlQahtani et al at four points. Results: Teeth generally developed earlier in females than in males. This was particularly notable in the age group of 5-14 years. However, this difference was usually visible in only one stage, not in all teeth. It has been determined that the mixed dentition period ended with the shedding of the second deciduous molars in both genders. Conclusion: The dental charts presented here included information that could be beneficial to dental clinicians in making appropriate diagnosis and planning orthodontic and surgical procedures. These charts also provided datasets for preliminary dental age estimation in Turkish children and young adults.
