Today, most children born preterm survive without major impairments. But high frequencies of cognitive and behavioural difficulties arise. Studies on dental behavioural management problems (DBMP) in these children are lacking. In addition, studies on caries prevalence are few and inconclusive.
This study aims to compare the frequency of behavioural problems and poor compliance with dental treatment in preschool children born preterm with those born full-term. The prevalence of caries was also studied.
The study group included 187 children born between 23 and 32 weeks of gestation. The control group constituted full-term children matched by age, sex, immigrant background, and dental operator. DBMP, number of dental visits, missed appointments, and caries between ages 3 and 6 were noted.
At age 3, but not at age 6, the prevalence of DBMP at clinical examinations was significantly higher in preterm children compared with the control group. Of the children who received dental treatments during preschool years, preterm children displayed significantly more DBMP. No significant difference in dental visits or in caries prevalence was found. Preterm children, however, missed significantly more dental appointments.
Children born preterm display a higher prevalence of DBMP at dental examinations and treatments during preschool years.
如今，大多数早产儿出生后能存活且无重大缺陷。但出现认知和行为困难的频率较高。对这些儿童的牙科行为管理问题（DBMP）的研究尚缺。此外，关于龋齿患病率的研究较少且尚无定论。
本研究旨在比较早产学龄前儿童与足月出生儿童的行为问题频率以及牙科治疗依从性差的情况。同时也研究了龋齿患病率。
研究组包括187名孕周在23至32周之间出生的儿童。对照组为按年龄、性别、移民背景和牙科医生匹配的足月儿童。记录3至6岁期间的DBMP、牙科就诊次数、错过的预约以及龋齿情况。
在3岁时，而非6岁时，与对照组相比，早产儿童临床检查时DBMP的患病率显著更高。在学龄前接受牙科治疗的儿童中，早产儿童表现出的DBMP明显更多。在牙科就诊次数或龋齿患病率方面未发现显著差异。然而，早产儿童错过的牙科预约显著更多。
早产儿童在学龄前的牙科检查和治疗中表现出更高的DBMP患病率。
