STUDIES ON ERUPTIVE STAGES OF PRIMARY DENTITION IN KOREAN INFANTS
Cho, Young-Ho ;
THE JOURNAL OF THE KOREAN ACADEMY OF PEDTATRIC DENTISTRY, volume 4, issue 1, 1977, Pages 7~18
The author carried out to determine the normal range of eruptive time, average age and order of eruption of primary teeth in korean infants. The examimation was given to 1757 healty infants(Male 1032, female 725) from afterbirth 4 months to 32 months. The results was as fallows. 1. The eruption of primary teeth was 0.57 months earlier in male than in female. 2. The average month of eruption of primary teeth was as follows; Upper primary central is
months Upper primary lateral is
months. Upper primary canine is
months. Upper first primary molar is
months. Upper second primary molar is
months. Lower primary central is
months. Lower primary lateral is
months. Lower primary camine is
months. Lower first primary molar is
months. Lower second primary molar is
months. 3. The eruptive order of the korean is different from that of the American and same to that of Japanese. 4. There is no significant right and left arch. 5. Generally, the eruption of primary teeth on the upper is 1.08 months earlier than on the lower; but the upper central is 2.16 months later than the lower and the upper second primary is 0.39 months later than the lower.
STUDIES ON THE ROOT RESORPTION OF THE DECIDUOUS TEETH.
Kim, Jin-Tae ;
THE JOURNAL OF THE KOREAN ACADEMY OF PEDTATRIC DENTISTRY, volume 4, issue 1, 1977, Pages 19~23
178 naturally exfoliated maxillary deciduous central incisors, 149 deciduous lateral incisors of children at exfoliation stage were studied on the degree and the tendency of the root resorption, and the age of exfoliation of the deciduous central and lateral incisors. The results were as follows; 1. The root of maxillary deciduous central and lateral incisors tended to be resorbed disto-lingually. 2. The age of exfoliation of maxillary deciduous central incisor was 7.27 year in male, 7.01 year in female, and the age of exfoliation of maxillary deciduous lateral incisor was 8.22 year in male, 7.77 year in female. 3. The exfoliation age of maxillary deciduous central and lateral incisors was earlier in female than in male.
THE STUDY ON THE POSITION OF THE MANDIBULAR FORAMEN IN KOREAN CHILDREN
Baek, Byeong-Joo ;
THE JOURNAL OF THE KOREAN ACADEMY OF PEDTATRIC DENTISTRY, volume 4, issue 1, 1977, Pages 24~27
The Author measured the position of the mandibular foramen with oblique cephalography in 43 5-aged, and 44 7-aged Korean children. The results of the studies were as follows; 1) The distance from the post. occlusal plane to the mandibular foramen was
. in age 5 and
. in age7 to the below. 2) The meeting point of the occlusal plane and anterior of the ramus to the mandibular foramen was
. in age5 and
. in age7. 3) The angulation between the occlusal plane and the line connecting the mandibular foramen and the meeting point of anterior border of the ramus with occlusal plane was
in age5 and
in age7 to the below. 4) % depth was
in age 5 and
in age 7. 5) The price of distance and angulation showed significant results at 0.01 level in KOLMOGOROV-SMIRNOV (TWO-SAMPLE) TEST.
CLINICAL STUDY OF THE GINGIVAL CONDITION FOLLOWING PLACEMENT OF STAINLESSSTEEL CROWN IN PRIMARY TEETH.
Kim, Ji-Tai ;
THE JOURNAL OF THE KOREAN ACADEMY OF PEDTATRIC DENTISTRY, volume 4, issue 1, 1977, Pages 28~34
The present study was undertaken to evaluate gingivitis and oral hygiene status of the crowned teeth comparing to controlled teeth by use of P. M. A. Index and Oral Hygiene. Index in children from
years old. The results were as followings. 1. In P. M. A. Index, satisfactory crowned teeth (1.53) showed statistically significant increment compare to the controlled teeth (0.68) (P<0.01). 2. In P. M. A. Index, unsatisfactory crowned teeth (2.22) showed statistically significant increment compare to the controlled teeth (0.70) (P<0 01). 3. In Oral Hygiene Index, satisfactory crowned teeth (1.49) showed statistically nonsignificant increment compare to the controlled teeth (1.27). 4. In Oral Hygiene Index, unsatisfactory crowned teeth (1.62) showed statistically nonsignicant increment compare to the controlled (1.39) 5. The severity of gingivitis following Oral Hygiene Index showed higher in crowed teeth than the controlled teeth. 6. The severity of giginvitis showed the highest in the unsatisfactory crowned teeth, the next was the satisfactory crowned teeth, and the controlled teeth showed the lowest.
EVALUATION OF CONSERVATIVE TREATMENT BETWEEN AMALGAM FILLING AND STAINLESS STEEL CROWN IN PRIMARY TEETH.
Woo, Won-Sup ;
THE JOURNAL OF THE KOREAN ACADEMY OF PEDTATRIC DENTISTRY, volume 4, issue 1, 1977, Pages 35~38
The study was performed to evaluate effects of Conservative treatment between amalgam filling and stainless steel crown. The selected subjects for this study was 350 children who have amalgam filling or stainless steel crown. The obtained results are as followings. 1. In amalgam filling teeth, 120 teeth (60.0%) showed marginal leakage, 57 teeth (28.5%) showed fracture of filling material and 28 teeth (14.0%) teeth showed periapical lesion. 2. In crowned teeth, 6 teeth (3.0%) showed hole on the surface of crown, 29 teeth (14.5%) showed avulsion of crown and 10 teeth (5.0%) showed periapical lesion. 3. After 12 months from examining date, 69 teeth (34.5%) showed sound condition in amalgam filling teeth and 155 teeth (75.2%) showed sound condition in crowned teeth.
A COMPARATIVE STUDY OF PROXIMAL CAVITIES FOUND BY CLINICAL AND BITE-WING ROENTGENOGRAPHIC EXAMINATIONS
Na, Seong-Sik ;
THE JOURNAL OF THE KOREAN ACADEMY OF PEDTATRIC DENTISTRY, volume 4, issue 1, 1977, Pages 39~44
150 "K" primary school children, from 6 to 10 years old, have been examined both clinically and radiographically for proximal caries in deciduous canine and deciduous posterior teeth and permanent first molar teeth. 1. 598 proximal cavities were diagnosed 154 (25.75%) were revealed by both examinations. 39 (6.52%) appeared on clinical examination only, but 405 (67.73%) were revealed by radiographic examination only. 2. The dental caries occurance on distal surface of first deciduous molar and mesial surface of second deciduous molar were revealed much higher values in all ages. 3. There is no significant differences observed between right and left arch. 4. Proximal cavities were revealed 1.7 times more in mandible than in maxilla.
A STATISTICAL STUDY ON THE DENTAL CARIES INCIDENCE IN CEREBRAL PALSY CHILDREN
Shin, Young-Soon ;
THE JOURNAL OF THE KOREAN ACADEMY OF PEDTATRIC DENTISTRY, volume 4, issue 1, 1977, Pages 45~52
The purpose of this study was to provide information concerning the dental caries incidence in cerebral palsy children, and to aid improvement of their oral health. The author examined 106 cerebral palsy children and 185 normal children as control group, between 3 and 15 years of age. The obtained results were as follows: 1) In the DMF person rate, DMFT rate and DMFT index, cerebral palsy children (74.68%, 16.24% and 2.76 respectively) showed remarkable increment compare to normal children. (14.28%, 6.95% and 1.20 respectively.) 2) In the df person rate, dft rate and dft index, cerebral palsy children(93.33%, 37.41% and 6.22 respectively) showed remarkable increment compare to normal children. (78.64%, 20.68% and 3.29 respectively.) 3) There showed no significant in sexual differences. 4) In the dental caries incidence of the permanent teeth, athetosis and paraplegia type was found higher than other types. 5) Cerebral palsy children was found higher than normal children in the oral hygiene index. 6) There was found out necessity of the continuous dental enlightenment and treatment through this study.
