Abstract

Purpose: Although a series of studies on OXIS contacts have been performed, studies regarding changes in OXIS contacts over time are lacking. Therefore, this study aimed to evaluate the change in contact type between primary molars after 3 years in children aged 3-7 years.

Methods: This longitudinal study was conducted using 2922 sectional die models of 926 children. At baseline (T0), the contact type between the primary molars was scored using replication via the sectional die model method according to the OXIS criteria. After 3 years, the sectional die models of the same children were scored using the same criteria (T1).

Results: McNemar's tests revealed a significant change in contacts from baseline to 3 years. The post hoc test explained specific changes in the contacts that were observed to be significant. These were O to X (p < 0.001), O to I (p < 0.001), O to S (p = 0.035), and I to X (p < 0.001).

Conclusions: A significant change in OXIS contact over time was observed. The O-type contact underwent the maximum change. The least and most stable contacts are the "O" and "I" types, respectively. This change in contact type with age may alter the risk of caries in children.

初级臼齿的 OXIS 接触点：会随时间变化吗？

目的：虽然已经开展了一系列关于OXIS接触的研究，但缺乏关于OXIS接触随时间变化的研究。因此，本研究旨在评估 3-7 岁儿童 3 年后基磨牙间接触类型的变化：这项纵向研究使用了 926 名儿童的 2922 个切面模型。在基线（T0）时，根据 OXIS 标准，通过截面模型复制法对初级臼齿之间的接触类型进行评分。3 年后，采用相同的标准对同一儿童的截面模型进行评分（T1）：McNemar 检验显示，从基线到 3 年期间，接触点发生了显著变化。事后检验解释了接触中观察到的显著变化。这些变化是 O 到 X 的变化（P 结论）：观察到随着时间的推移，OXIS 接触发生了重大变化。O 型接触变化最大。最不稳定和最稳定的接触分别是 "O "型和 "I "型。接触类型随年龄的变化可能会改变儿童患龋的风险。

期刊介绍： The aim and scope of European Archives of Paediatric Dentistry (EAPD) is to promote research in all aspects of dentistry for children, including interceptive orthodontics and studies on children and young adults with special needs. The EAPD focuses on the publication and critical evaluation of clinical and basic science research related to children. The EAPD will consider clinical case series reports, followed by the relevant literature review, only where there are new and important findings of interest to Paediatric Dentistry and where details of techniques or treatment carried out and the success of such approaches are given.
