Objectives: The 2018 Basic Health Research (RISKESDAS), conducted by the Ministry of Health of the Republic of Indonesia showed a high prevalence of dental caries (88.8%) in Indonesia and suggested that smoking tobacco was associated with an increased risk of dental caries. This study analyzed the association between tobacco smoking and dental caries in the Indonesian population. Methods: This was a cross-sectional analysis of secondary data collected from RISKESDAS 2018. The study population included 35 391 Indonesians aged ≥10 years from all 34 provinces. The decayed, missing, and filled teeth (DMFT) index was used to measure dental caries. Smoking status was assessed qualitatively based on smoking activity, and the level of smoking exposure was assessed based on the Brinkman index. A multivariable logistic regression analysis was employed to examine the relationships of smoking status and smoking exposure levels with the DMFT index. Results: Of the population aged ≥10 years, 36% had a DMFT≥8 (females: 37.5%, males: 33.9%). Almost one-fourth (23.4%) were current smokers, and 4.1% were ex-smokers. Furthermore, 26.4% had a Brinkman index ≥400, indicating heavy smoking. According to the multivariate analysis, current smoking status was associated with the risk of DMFT≥8 in males (adjusted odds ratio [aOR], 1.40; 95% CI, 1.27 to 1.55; p<0.001) and overall (aOR, 1.07; 95% CI, 1.00 to 1.14; p=0.037). In females, ex-smoking was associated with a 41% higher risk of DMFT≥8 (aOR, 1.41; 95% CI, 1.07 to 1.84; p=0.014). Heavy smoking was associated with a higher risk of DMFT≥8 in males (aOR, 1.38; 95% CI, 1.25 to 1.52; p<0.001) and females (aOR, 1.24; 95% CI, 1.03 to 1.50; p=0.022). Conclusions: Tobacco smoking was associated with dental caries in the Indonesian population.

Dental caries causes the majority of tooth loss among Koreans. Korea is experiencing an increase in dental caries. And it shows a high prevalence of caries in preschool children, which contrasted with the much-improved situation in developed countries. So, it is important to control caries from preschool periods in Korea. Recently, inspections of the teeth of preschool children for evidence of dental disease became a legislative duty in Korea following Oral Health Act(2000). But, standardized oral health programs in preschool children is not yet proposed. Therefore, it is necessary to develop an community based oral health program in preschool children. The purpose of this study was to obtain basic data for the development of community based oral health program in preschool children of Sungnam city. Oral health status in primary dentition were surveyed in 862 2-6 year-old preschool children of Sungnam city by WHO criteria. From the data, df rate, percentage of preschool child ren with active caries, dft index, dt rate, percentage of preschool children with pit and fissure sealant of each age were calculated, and discussed. The obtained results were as follows : 1. The experience of dental caries in primary dentition showed a tendency to increase quickly between 2 and 3 year old children. So, the oral health program in preschool children should be developed to prevent dental caries and control their oral health under three years of age. 2. In 5 year-old children, the percentage with active caries was 60.8% and dft index was 5.06. The dt rate showed a tendency to decrease as proportion to age, but even though 6 year-old children, the dt rate was 47.7%. Therefore, the annual screening dental examination and oral health education programs at the institution for preschool children should be developed to detect and treat dental caries in primary dentition at early stage. 3. The percentage of preschool children with pit and fissure sealant at six years of age was 10.2%. So, pit and fissure sealant and professional fluoride application programs in Public Health Center should be developed to prevent dental caries. 4. Also, it is necessary to establish oral health goals in preschool children and develop water fluoridation program 10 improve and preserve oral health of preschool children in Seongnam city, effectively.

The purpose of this study was to obtain the data for dental caries experience and occlusal pattern to utilize these data for motivating oral health promotion and activating oral health care programme in preschool children of multicultural family. Caries prevalence on primary teeth was surveyed for 3-5 years old 190 children of multicultural families in Chonbuk province. The results were as follows : 1. Dental caries prevalence rate of primary teeth (dmf rate) was 61.7% at 3 years of age, 88.7% at 4 years of age, and 92.6% at 5 years of age (p>0.05). 2. Average score of dmft index was 2.22 at 3 years of age, 4.97 at 4 years of age, and 6.62 at 5 years of age (p>0.05). 3. Most of the caries-prevailed tooth was maxillary primary central incisor and showed 28.8% at 3 years of age, 56.7% at 5 years of age. 4. dmft index and dmfs index of children of Vietnamese, Cambodian, and Filipinos women were higher than those of Chinese and Japanese. 5. In sagittal primary molar relationship, flush terminal plane type was 82.6%, distal step type was 5.2% and mesial step type was 8.4%. This study is the first report for children of multicultural families in Korea. More attention for children of multicultural families will be needed in aspect of oral disease prevention and treatment.

This survey was performed as a pilot of comprehensive survey of 18-month old infants which is an important period in pediatric dentistry. Through the oral examination of 154 infants of 18-month age, labored at Pusan National University Hospital and Ilsin Christian Hospital, and direct interview with their first caregivers (mother in most cases), we investigated into the state of their weaning and feeding, between-meal snacks, oral hygiene care, tooth eruption and dental caries and obtained the results as follows : 1. 73% of the infants had not yet weaned, and 82% of which were being milked during or before sleep without oral hygine care. 2. Snacks were taken in order of fruits, biscuits, cheese, bread and candies, and beverages in order of water, fermented milks, milk, sugared juice, fresh fruit juice. 61% of the infants ate snacks irregularly. 3. The toothbrush for infants was the most popular way of oral hygiene care. The mean age of initiation of tooth brushing was 13.8 months and the mean frequency was 1.6 times a day. 4. The incisors in all infants, the 1st molars in 86%, and canines in 66% were erupted. The average number of erupted teeth was 14.1. 5. The caries prevalence rate was 27.3% and 73% of total caries was observed in maxillary deciduous incisors. dmft index was 0.97. Through these results, it was concluded that a systematic education about weaning time, mode of snacking and the way of oral hygine care is required for the parents.

For the purpose of knowing oral status of handicapped persons and surveying correlative factors, authors interviewed and inspected 259 persons (cerebral palsy 143, mental retardation 101, Down's syndrome 15) from six year to thirty years old in Kwangju. The results were as follows. 1. The dmf rate and dft index of handicapped persons according to age were lower than that of report of normal persons. 2. The DMF rate and DMFT index of handicapped persons increased with age and were similar to or lower than that of report of normal persons by the age of twenty, but were higher after that age. There was no significant difference between handicaps in DMFT rate. 3. Percentage of toothbrushing by himself or herself was 74% in mental retardation, 69% in Down's syndrome, and 48% in cerebral palsy and the frequency of toothbrushing per day of mental retardation, Down's syndrome was higher than that of cerebral palsy. The frequency of toothbrushing per day increased with age. The number of toothbrushing of handicapped persons was slightly higher than that of report of normal persons. 4. Prevalence of gingivitis was 62% in cerebral palsy, 48% in Down's syndrome and 60% in mental retardation. Prevalence of gingivitis increased with age, and was higher than that of report of normal persons. 5. Percentage of tooth anomaly was 15% in Down's syndrome, 8.5% in mental retardation and 4.9% in cerebral palsy. In this study, dental caries of handicapped persons was similar to or lower than that of normal persons and increased with age. The prevalence of gingivitis was much higher in handicapped persons.

Purpose : To evaluate the efficacy of panoramic radiography by comparing the results of clinical examination with radiographic findings. Materials and Methods: We studied 190 patients (20 men and 170 women; mean age, 40 years; range, 22 to 68 years) who visited the health promotion center of Korea Medical Science Institute and were examined both clinically and by panoramic radiography. We compared results from both examinations. Treatment options by clinical examination were described as "no treatment indicated", "treatment of dental caries", "removal of calculus", "treatment of periodontal disease", "prothodontic treatment" and "extraction of the third molar". Findings taken from the panoramic radiography were: dental caries, periapical lesion, alveolar bone loss, calculus deposition, retained root, impaction of the third molar, disease of maxillary sinus, bony change of mandibular condyle, etc. Results: The prevalence of panoramic findings were: 37.9% of dental caries, 17.4% of periapical lesions, 44.7% of alveolar bone losses, 62.6% of calculi deposition, 7.9% of retained roots, 26.8% of third molar impactions, 6.3% of diseases of maxillary sinus, 2.1 % of bony changes of mandibular condlye and 35.8% of miscellaneous lesions. Abnormal conditions revealed by panoramic radiography which had not been discovered on clinical examination were: 24.2% of the patients had dental caries, 17.4% had periapical lesions, 7.4% had calculi deposition, 5.3% had retained roots, 15.3% had third molar impactions. The opposite cases were: 5.2% had dental caries, 12.6% had calculi deposition, and 9.5% had third molar impactions. Conclusion: The use of panoramic radiography as a supplement to the clinical examination might be a valuable screening technique.

The author has made a study on the classification of the mandibular 3rd molars of Korean youths through dental radiography by means of Pell & Gregory's classification and on the prevalence of the dental caries of distal surface of the mandibular 2nd molar adjacent to the mandibular 3rd molars turned anteriorly. The results are as follow; 1. It was found that the largest case number was class I (272 cases, 52.9%) in the relation of the tooth to the ramus of the mandible and 2nd molar. 2. The mesio-angular position was the largest number (239 cases, 46.5%) in the relation of the long axis of the impacted mandibular 3rd molar to the long axis of the 2nd molar. 3. The mesio-angular position of class I was the largest number (140 cases, 27.2 %) in the relation of the tooth to the ramus of the mandible and 2nd molar and the long axis of the impacted mandibular 3rd molar to the long axis of the 2nd molar. 4. The average angle of the long axis of mandibular 3rd molar in mesioangular position or horizontal position to the occlusal plane was 143° 5. Mandibular 3rd molar with lesion such as dental caries or pericoronitis was 73 cases (14.2). 6. The caries incidence rate of the distal surface of the 2nd molar was about 3.1%.
