The purpose of this study was to investigate the prevalence of severe early childhood caries and feeding pratices in preschool children. The subjects of study were six hundred and seventy-two preschool children in Iksan city. Severe early childhood caries(S-ECC) was defined as the presence of one or more cavitated, missing due to caries, or filled smooth surfaces in primary maxillary anterior teeth. The caregivers of children were given a questionnaire including age, gender, birthweight, and feeding practices. The prevalence of S-ECC was 34.5%. The prevalence was significantly higher when there were the habit of sleeping while feeding, the habit of feeding sour or sweet content in the bottle, and the habit of using the pacifier. Birth weight, breast-feeding, bottle-feeding, and the sippy cup habit showed no significant association with the prevalence of S-ECC. There were significant positive associations between breast-feeding and sleeping while feeding, between bottle-feeding and the pacifier, between sleeping while feeding and sour or sweet content in the bottle, between sleeping while feeding and the sippy cup, between sleeping while feeding and the pacifier, and between the sippy cup and the pacifier. There were significant negative associations between breast-feeding and the pacifier.

Purpose: To investigate the effect of nonnutritive sucking(NNS) on the heart rate, oxygen saturation, and behavioral state of premature infants. Method: From December 15, 2004 to February 15, 2005, 20 premature infants hospitalized in the neonatal intensive care units were assigned to an experimental group (10), or a control group (10). Circular pacifiers for premature infants (Johnson, U.S.A.), which had been packed with $2{\times}2$ gauzes to create a vacuum, were used for 5 minutes, one hour after feeding for 5 days. Heart rates and oxygen saturation were checked every minute for 10 minutes once a day and behavioral states were monitored through video recording at the same time. Results: Changes in heart rate, oxygen saturation and behavioral state were found to show significant differences between the experimental group and the control group according to the point in time, and interactions were found between the group and the point of time. However, for behavioral state, no significant difference was found between the experimental group and the control group after the NNS was removed. Conclusion: From the results of this study it is possible to conclude that NNS is a positive intervention to bring about increased oxygen saturation and soothed behavioral state for premature infants.

Purpose: This study is to assess and compare the analgegic effects of $25\%$ sucrose coating pacifier and pacifier. Method: The participants are 75 healthy infants of neonatal age 1-7 days and randomized to receive heel prick before 2 minutes to blood sampling and physiological test in Nursery of A Medical Center from 24. January to 28, February, 2003. The experimental group assigned to one of three treatment groups: no treatment, a pacifier, $25\%$ sucrose coating pacifier. Collected data were analyzed with the SPSS 11.0 program using $x^2$-test, one-way ANOVA and Scheffe, repeated mesured ANOVA. Results: The pain score of $25\%$ sucrose coating pacifier is lower than no treatment group and pacifier group. In heart rate, there were statistical significant differences between three groups. In repiratory rate, there were no statistical significant differences between three groups. In $SaO_2$, there were statistical significant difference between three groups. Conclusion: The $25\%$ sucrose coating pacifier showed pain relief effect in behavior responses and heart rate and $SaO_2$. Accordingly, the sucrose coating pacifier should be applied nursing intervention for simple pain management as heel prick.

Purpose: The purpose of this study was to examine the pain reducing effects of the dextrose-coated pacifier on venipuncture in premature infants. Methods: The design of this study is a nonequivalent control group pretest-posttest design and a crossover trial. The analysed cases were 40 premature infants (20 in experimental group and 20 in control group) in neonatal intensive care unit of a University Hospital, Gyeongnam Province, Korea. The data were collected from April to October, 2009. The experimental treatment was carried out nursing 20% dextrose-coated pacifier on venipuncture for IV injection. The instruments were $O_2$ saturation and heart rate on pulse oxymeter monitor to measure physiologic pain responses, and NIPS to measure behavioral pain responses. Collected data were analyzed with $x_2$ test, t-test using SPSS program. Results: The effects of the 20% dextrose-coated pacifier were found in the physiologic (only heart rate) and behavioral pain response on venipuncture. Conclusion: These finding is suggested that the dextrose-coated pacifier could be an effective nursing intervention for reducing pain on venipuncture in premature infants.

Purpose : We compared the pain reducing effect of orally administered glucose solution with EMLA cream and pacifiers during venipuncture in newborn infants. Methods : Fifty newborn infants(30 prematures) were enrolled in this study. We performed these four pain-reducing methods to all infants in serial order. Group A(control) did not receive any treatment; to group B, EMLA cream was applied on the skin for 1 hour; group C(or D) received 10 percent(or 30 percent) glucose solution orally; group E used pacifiers. Symptoms and signs associated with pain at venipuncture were measured with the Premature Infants Pain Profile(PIPP) scale. Results : There was no significant difference in the PIPP scores between preterm and fullterm infants. The mean PIPP scores of groups were A : $12.5{\pm}2.5$, B : $10.1{\pm}2.6$, C : $9.4{\pm}2.0$, D : $6.5{\pm}2.1$ and E : $8.7{\pm}2.3$; the mean scores of groups B, C, D and E were significantly lower than that of group A(all, P<0.001 except B(P<0.05)), and the mean score of D was significantly lower than those of B, C and E(P<0.001, P<0.005, P<0.05, respectively). The percentages of patients with PIPP scores above 6, which means pain, were A : 100 percent, B : 82 percent, C : 56 percent, D : 40 percent and E : 70 percent. The percentages of patients with PIPP scores above 12, which means severe pain, were A : 72 percent, B : 30 percent, C : 22 percent, D : 0 percent and E : 14 percent; that of group D was clearly lowest. Conclusion : These results support the use of oral glucose solution, EMLA, and pacifiers for pain reduction as effective intervention at venipuncture in newborn infants. The most effective method was a 30 percent oral glucose solution.
