摘要

研究目的：比較早產兒及足月兒乳齒列萌出狀態，並評估新生兒因子及營養因子是否造成影響。
研究對象與方法：研究對象來自高雄醫學大學新生兒科，包含72位早產兒與141位足月兒（年齡為6-43個月大）， 由兒童牙科醫師及小兒科醫師分別進行口腔檢查及身體檢查，新生兒因子及營養因子則由病歷及問卷進行蒐集。結果以two-way ANOVA比較，p值為0.05。
結果：當以出生後年齡計算時，早產兒萌出乳齒總數少於足月兒(p=0.0126)，但依照年齡分層後唯一顯著的年齡層是6-11個月大的族群（3.13±0.44顆及4.82±0.42顆，p=0.0079）。但若以矯正年齡計算，足月兒與早產兒的萌出乳齒總數沒有顯著差異(p=0.9392)。亦沒有任何一項新生兒因子或營養因子對萌出乳齒總數造成影響（p值均大於0.05）。
結論：早產兒的乳齒萌出狀態與足月兒並無顯著差異，亦不受新生兒因子及營養因子影響，唯需將矯正年齡列入考慮。

Qbjective: The purposes of this study were to compare the eruption status of primary teeth between children of pre-term and full-term birth and to evaluate the effects of neonatal factors and nutritional status on primary teeth eruption.
Subjects & Methods: We recruited 72 pre-term, and 141 full-term birth children (aging from 6 months to 43 months) in Chung-Ho Memorial Hospital, Kaohsiung Medical University (KMUH). Oral and medical examinations were performed by a pediatric dentist and pediatricians, respectively. Medical charts and questionnaires were used to collect other neonatal and nutritional factors. Two-way ANOVA was utilized to compare the results, and the p value lower than 0.05 was considered statistically significant.
Results: When using chronological age in the calculation, children of pre-term birth had slightly delayed primary teeth eruption than those of full-term birth (p=0.0126), but only for children in the group aged 6-11 months (3.13±0.44 and 4.82±0.42, respectively, p=0.0079) When using corrected age in the calculation, children of pre-term birth did not have significant delayed primary teeth eruption compared with those of full-term birth (p=0.9392). No specific neonatal factor or nutritional factor had impact on the total numbers of eruption teeth (all the p values were higher than 0.05).
Conclusion: Eruption status of primary teeth of pre-term birth children was not significantly different from that of full-term birth children, and no specific neonatal factor or nutritional factor had impact on it. However, the corrected age of pre-term birth must be born in mind.
