Abstract

Purpose: Dental development is delayed in individuals born with oral clefts. The purpose of this study was to determine: (1) the proportion of individuals with severe delays in dental maturation; and (2) if there are different patterns of dental development timing, taking into consideration the chronological age of the individual.
Methods: Dental maturation was estimated by the Demirjian method in children aged seven to 12 years with and without clefts. The differences between dental age and chronological age between groups were compared using the Mann-Whitney test, with an alpha of 0.05. A subset of 50 individuals in each group had at least two panoramic radiographs at least two years apart. These were analyzed to determine dental maturation trajectories in comparison with chronological age to identify individuals with different patterns of development.
Results: The sample consisted of 201 children with oral clefts and 201 without clefts. Individuals born with clefts had, on average, two months of delay in dental maturation compared to those without a cleft. Five patterns of differences were identified between dental and chronological age. These distributions were statistically significant statistically (P <0.001).
Conclusion: Children born with cleft lip and palate have delayed tooth maturation and a high frequency of greater delays in tooth maturation over time compared to individuals born without clefts.

牙齿年龄和实足年龄的不同模式:出生时有或没有唇裂的个体的纵向评估。

目的:先天性唇裂患者的牙齿发育迟缓。本研究的目的是确定:(1)牙齿成熟严重延迟的个体比例;(2)如果牙齿发育时间有不同的模式，要考虑到个体的实际年龄。方法:采用Demirjian法对7 ~ 12岁伴有和不伴有唇裂的儿童进行牙成熟评估。采用Mann-Whitney检验比较各组牙龄和实足年龄的差异，alpha值为0.05。每组50人的一个子集至少间隔两年进行两次全景x光片检查。这些分析，以确定牙成熟轨迹与实足年龄的比较，以确定个体不同的发展模式。结果:201例唇裂患儿和201例非唇裂患儿。与没有唇裂的人相比，出生时患有唇裂的人的牙齿成熟平均延迟了两个月。在牙齿年龄和实际年龄之间确定了五种差异模式。结论:唇腭裂患儿的牙齿成熟延迟，且随着时间的推移，唇腭裂患儿的牙齿成熟延迟的频率高于非唇腭裂患儿。

期刊介绍： Acquired after the merger between the American Society of Dentistry for Children and the American Academy of Pediatric Dentistry in 2002, the Journal of Dentistry for Children (JDC) is an internationally renowned journal whose publishing dates back to 1934. Published three times a year, JDC promotes the practice, education and research specifically related to the specialty of pediatric dentistry. It covers a wide range of topics related to the clinical care of children, from clinical techniques of daily importance to the practitioner, to studies on child behavior and growth and development. JDC also provides information on the physical, psychological and emotional conditions of children as they relate to and affect their dental health.
