The aim of this study was to investigate possible links between competitive swimming during the growth phase and the development of the dentoalveolar arches.
The study sample included 100 swimmers and a control group of 100 age-matched non-swimmers who had never practised swimming or related sports. Subjects who had had previous orthodontic treatment were excluded. Overjet, overbite, sagittal and transverse parameters, arch dimension, crowding and oral habits were recorded.
In the swimmers, there was a significantly higher frequency of molar symmetry (P=0.04), together with a greater number of Class I subjects. The overjet in the swimmers was mainly normal, but the arch dimensions were significantly wider (+10% in the upper arch; P<0.001). Similarly, the swimmers showed significantly less severe crowding (P<0.001) and significantly reduced oral habits (P<0.001).
Our data and analysis demonstrate that competitive swimming during the growth phase has a favourable effect on dental arch development in the sagittal, vertical and transverse planes.
本研究的目的是调查生长阶段的竞技游泳与牙槽弓发育之间可能存在的联系。
研究样本包括100名游泳运动员和100名年龄匹配的非游泳运动员组成的对照组，这些非游泳运动员从未进行过游泳或相关运动。曾接受过正畸治疗的受试者被排除在外。记录覆盖、覆合、矢状和横向参数、牙弓尺寸、牙列拥挤情况和口腔习惯。
在游泳运动员中，磨牙对称性的频率显著更高（P=0.04），同时I类受试者的数量更多。游泳运动员的覆盖主要正常，但牙弓尺寸明显更宽（上颌弓宽10%；P<0.001）。同样，游泳运动员的牙列拥挤程度明显较轻（P<0.001），口腔习惯也明显减少（P<0.001）。
我们的数据和分析表明，生长阶段的竞技游泳在矢状、垂直和横向平面上对牙弓发育有有利影响。
