The purpose of this study was to provide basic information for improving oral health and dental hygiene through comprehensive dental hygiene care. The subjects in this study were 54 patients who had been treated for 4 weeks in clinic of the Dental Hygiene Department of G University under comprehensive dental hygiene control and care and measured their oral condition, intensity of oral malodor, Simplified Oral Hygiene Index (S-OHI), and Modified Personal Hygiene Performance Index (PHP-M), and surveyed their oral health behavior and oral health consciousness. The results of the study were as follows: 1. The intensity of malodor decreased by 16.49ppb from 75.33ppb on the first visit to 50.84ppb on the last visit when the comprehensive dental hygiene care had been finished. 2. As to change in S-OHI according to gender between the first visit and the last visit for comprehensive dental hygiene care, S-OHI decreased from 2.89 on the first visit to 1.16 on the last visit, and the difference was statistically highly significant. 3. As to change in PHP-M index by tooth according to gender and age between the first visit and the last visit, PHP-M index of the first 6 teeth decreased very significantly from 0.50 on the first visit to 0.34 on the last visit. 4. As a whole, significant improvement was observed in every tooth. According to gender and age, PHP-M index for Tooth No. 26, 36 and 32 decreased significantly in men and women, and those aged under 30 and those aged 30 or over, but for Tooth No. 13 and 15 and 44 it decreased significantly only in men and those aged 30 or over, and for Tooth No. 44 only in men. As presented above, the oral health behavior and oral health consciousness of the visitors to the oral prophylaxis practice room are very important, and it is necessary to enhance their interest in and knowledge of how to improve oral health. Furthermore, comprehensive dental hygiene care required for improving the visitors' oral health.

첫 치과 내원 시기는 치아가 처음으로 맹출 하는 시기나 늦어도 12개월 이내가 추천된다. 추천 시기 이전에도 영아들은 여러가지 이유로 치과에 내원할 수 있지만, 이와 관련된 연구는 거의 찾아보기 어렵다. 이 연구의 목적은 치과에 내원한 영아들의 인구학적특성 및 치과적 특성을 알아보는 것이다. 2006년 1월부터 2015년 12월까지 경희대학교 치과병원 소아치과에 내원한 1세 미만의 영아 419명의 의무기록을 수집하고 분석하였다. 내원 원인의 빈도는 치아 외상(47.5%), 선천치/신생치(19.8%), 치아 우식(8.1%), 유치 맹출과 관련된 문제들(4.3%), 소대 이상(3.6%), 연조직 부종(3.6%), Bohn's nodule(3.3%), 구순구개열(2.9%), 치은신생물(1.9%), 혀의 궤양(1.7%), 구강 검진(1.4%), 법랑질형성이상(1.2%), 턱관절에서의 비정상적인 소리(0.7%) 순이었다. 이번 연구를 통해 실제로 영아의 건강에 해를 끼칠 수 있는 구강 질환들에 대해 확인하였다. 이러한 구강 증상들은 주로 영아와 접할 기회가 많은 소아청소년과 의사나 산부인과 의사에 의해 발견이 되기 쉬우므로, 구강 질환이 적절하게 관리될 수 있도록 이들을 대상으로 한 교육이 필요할 것으로 생각된다.

Dental caries in infants is a representative oral disease causing the malocclusion of permanent dentition and developmental variations in the permanent teeth, so it is very important to manage caries in infants. Thus, in order to survey mothers who visited pediatric dentistry concerning their awareness of nursing bottle caries and to obtain data necessary for developing education materials to prevent nursing bottle caries, the present study conducted a survey using a self reporting questionnaire with 205 mothers who visited the Pediatric Dentistry of a dental hospital in Cheonan with a child aged below 5 during the period from June 7 to August 2 in 2008, and obtained results as follows. 1. The awareness of dental caries was highest in the group aged over 37 months 96.8%, and next in order of age 13~24 months 96.5%, 25~36 months 94.5%, and younger than 13 months 83.3%. 2. The awareness of nursing bottle caries was highest in infants aged over 37 months 58.7%, and next, in 13~24 months 57.9% and in 25~36 months 54.8%, and lowest in infants younger than 13 months 33.3%, suggesting the necessity of education on nursing bottle caries(p=0.423). 3. As to the time of the first visit to dental clinic, 50.0% of infants younger than 13 months, 52.6% of those aged 13~24 months, and 49.3% of those aged 25~36 months replied the completion of the eruption of primary teeth, and 36.5% of those aged over 37 months replied the occurrence of dental caries. Thus, the motives for visiting dental clinic were different among the age groups, and the differences were statistically significant(p=0.005). 4. The age of toothbrushing to be started by mother's opinion was 6 months in 0.5%, 12 months in 68.8%, 18 months in 22.9%, 24 months in 5.9%, and 25 months in 1.0%, and no statistically significant difference was observed according to age. 5. The number of toothbrushing was usually once a day after meal. and increased by in age was shown statistically significantly difference(p=0.035). 6. The most frequent method of preventing nursing bottle caries was regular toothbrushing in all the age groups, and next restriction of sugar intake, regular dental consultation, and fluoridation in order The most effective prevention of dental caries was regular visit to dental clinic and next, toothbrushing after meal.

Background: Administering anesthesia in dentistry can be distressing for patients, especially those with dental fear and anxiety. Needle pain during local anesthesia is a common concern in intraoral procedures. This study aimed to compare pain perception in 4-6-year-old children following intraoral dental injections with 26- and 31-gauge needles. Methods: Fifty healthy children were divided according to age into Group I (N = 25; 4-5 years) and Group II (N = 25; 5-6 years). Each group was further subdivided according to the needle gauge as follows: Group IA (26 gauge), Group IB (31 gauge), Group IIA (26 gauge), and Group IIB (31 gauge). Using a lottery method, the gauge of the needle to be used at the first visit for local anesthesia administration was selected. Children's reactions to pain were evaluated using a Modified Behavioral Pain Scale. Immediately after administration of local anesthesia, pain perception was evaluated using the Faces pain rating scale. In the subsequent visit, another needle gauge was used to administer local anesthesia, and the previously described evaluations were performed. At the third appointment, the child was shown both syringes and asked to choose one of the syringes they preferred, and the choice was noted. Results: When local anesthesia was administered using a 31-gauge needle, pain perception was similar between the two groups. In group II, the children demonstrated significantly higher arm and leg movements (P = 0.001). However, the difference was significant in group I alone (P < 0.001). Conclusion: Irrespective of age, anesthesia with a 31-gauge needle resulted in significantly lower pain perception than anesthesia with a 26-gauge needle.

Objectives: This study aimed to develop and validate machine learning (ML) models using H₂O-AutoML, an automated ML program, for predicting medication-related osteonecrosis of the jaw (MRONJ) in patients with osteoporosis undergoing tooth extraction or implantation. Patients and Methods: We conducted a retrospective chart review of 340 patients who visited Dankook University Dental Hospital between January 2019 and June 2022 who met the following inclusion criteria: female, age ≥55 years, osteoporosis treated with antiresorptive therapy, and recent dental extraction or implantation. We considered medication administration and duration, demographics, and systemic factors (age and medical history). Local factors, such as surgical method, number of operated teeth, and operation area, were also included. Six algorithms were used to generate the MRONJ prediction model. Results: Gradient boosting demonstrated the best diagnostic accuracy, with an area under the receiver operating characteristic curve (AUC) of 0.8283. Validation with the test dataset yielded a stable AUC of 0.7526. Variable importance analysis identified duration of medication as the most important variable, followed by age, number of teeth operated, and operation site. Conclusion: ML models can help predict MRONJ occurrence in patients with osteoporosis undergoing tooth extraction or implantation based on questionnaire data acquired at the first visit.

Purpose. This study examined the predictive factors enabling access to children's oral health care at the level of financial barriers, beliefs, and the provider. Methods. In-depth interviews were conducted with 320 immigrant mothers of low-income families regarding their use of oral health services for children aged four to eight years old. Access to oral health care was measured with frequency of planned dental visits, continuity of care, and age at first visit to dentist. Results. The mother took her child to the dentist at a younger age if she received referrals to a dentist from pediatrician. Regular dental visits were significantly related to household income, provider availability on week-ends, and insurance coverage. The extended clinic hours in the evenings, and the belief in the importance of the child's regular dentist visits increased the likelihood of continuing care. The mothers perceiving a cost burden for the child's dental care were also less likely to return to the dentist. Conclusion. The available care delivery system, coordinated medical care, and health beliefs were among important predictors of the health service use. The study findings suggest need for culturally competent dental health interventions to enhance access to oral health care among particularly vulnerable populations such as low-income children in Korean communities.

The research was conducted to 100 child patients selected by random sampling, which got a Dentocult-SM test in the first visit and then was being continuously managed, out of child patients of a pediatric clinic located in Gyeonggi-do. The period of there search is one year from June 2007 to May 2008, Using Dentocult-SM test, we analyzed the correlation between the distribution of dental plaque, a streptococcus mutans in saliva and condition of dental caries cavity in the teeth of child patients, then we measured the distribution of a streptococcusmutans. According to SM score, we applied incremental oral heath care for child patients to clinical and obtained the following results, 1. In terms of the age of child patients in research, the number of 3 years old patients was 29(lst ranked), the number of 2 years old patients was 28(2nd ranked). 2. The result of SM score showed that female child patients(52.0%) was higher than male ones in negative, male child patients(52.0%) was higher than female ones in mild, female child patients(68.2%) was higher than male ones in moderate, male child patients(57.1%) was higher than female ones in severe. 3. At the first visit, the SM score showed statistically remarkable difference between dt and dmft. We can also confirm the average of severe is the highest. 4. At the second visit, the SM score showed statistically remarkable difference among dt, ft, and dmft index We can also confirm the average of severe is the highest. 5. At the third visit, The SM score showed statistically remarkable difference among dt, ft, and dmft index We can also confirm the average of severe is the highest. 6. The comparison of dmft index differences to SM score showed statistically no remarkable difference in incremental oral heath care for negative and mild, In addition to that, we can confirm that the incremental oral heath care makes statistically remarkable differences in moderate and severe. 7. The comparison of dt index differences to SM score showed statistically no remarkable difference in incremental oral heath care for negative, mild, and moderate, In addition to that, we can con firm that the incremental oral heath care makes statistically remarkable differences in severe. 8. The comparison of mt index differences to SM score showed statistically no remarkable difference in incremental oral heath care for mild and moderate, In addition to that, we can confirm that the incremental oral heath care makes statistically remarkable differences m severe. 9. The comparison of ft index differences to SM score showed statistically no remarkable difference in incremental oral heath care for mild, In addition to that, we can confirm that the incremental oral heath care makes statistically remarkable differences in negative, moderate, and severe. 10. According to the comparison of dmft index to the age, the 4 years old patients showed the highest number(5.50 in the first visit and 6,08 in the second one). In the third visit, the 6 years old patients showed the highest number(7.00). By the above results, we can find that the incremental oral heath care by SM score makes the results of oral care better. Therefore, the improvement or maintenance in oral health of child patients needs continuing personal oral health management and regular systematic management focused on prevention by the specialist.
