치아 맹출전 시행한 기관 삽관이 유치열기에 미치는 영향에 대한 증례보고

Delayed eruption and abnormal morphology of the primary incisors following intubation may be due to follicular displacement and localized trauma caused by the process of intubation. Result of such damage included palatal groove formation, defective incisors and acquired clefts. This clinical report presents effect of intubation on the primary dentition of premature low-birth-weight children prior to tooth eruption

Single Median Maxillary Central Incisor(SMMCI) 환아의 증례보고

Anatomic abnormalities of teeth development include the presence of a single maxillary central incisor at midline instead of two central incisors. The incidence of cases with a single maxillary central incisor is approximately 1 in every 50,000 live births. single median maxillary central incisor(SMMCI) may be a integral manifestation of any one of a number of syndromes. It has been reported an association with several midline disorders which have varied in severity. A SMMCI has also been reported as an isolated finding. But in some cases, it has been considered as an incomplete expression of autosomal dominant holoprosencephaly. So any patient who appears for treatment with a SMMCI should be referred for a detailed medical examination to exclude other associated systemic abnormalities and for mutation analysis to facilitate correct diagnosis and the provision of appropriate genetic counseling. Early orthodontic treatment is needed to minimalize emotional trauma of child. This case report was about three patients with a SMMCI as isolated finding. The purpose of these case reports was to present cases of single maxillary central incisor not associated with other disorders

Comprehensive Factors Influencing Quality of Life of Elders Utilizing Senior Welfare Centers

Purpose: The purpose of this study was to investigate the influencing factors on the quality of life of elders. Methods: Data were collected from August 25, September 1, 2014, and participants were 300 elders who were using senior welfare centers. Descriptive statistics, t-test, one-way ANOVA, Pearson correlation coefficient, and stepwise multiple regression were used for data analysis. Results: Elders who were more painful, highly perceived health status, self-esteem and social support, and lower depression showed relatively higher quality of life. Also, there were strong correlations between quality of life and depression (r=-.737) /perceived health status (r=.709). actors predicted quality of life of elders were perceived health status (β=.349), depression (β=-.267), social support (β=.172), self-esteem (β=.170), pain (β=-.130), income (β=.113), and level of education (β=.064). These 7 factors explained 78.2% of the variance in quality of life of elders (F=154.49, p<.001). Conclusion: Therefore, in order to improve the quality of life of elders, a systematic approach is necessary through multilateral cooperation among comprehensive sectors
