最近的研究波动牙齿不对称孤立的单一压力作为致病因素。由于大多数压力源本质上是复合的，因此本研究旨在确定压力源相互作用对诱导牙齿不对称波动的影响。怀孕的大鼠被分配到六个治疗组中的一个，并受到热，冷，噪音和蛋白质剥夺的各种组合的压力。波动的牙齿不对称的水平进行了评估，发现所有协议产生更高水平的不对称比对照组动物。噪音和蛋白质减少表现出加性效应和应激源的相互作用产生的窝仔数减少。最后对这一领域的进一步研究提出了建议。
Recent studies on fluctuating dental asymmetry have isolated single stressors as causative agents. Since most stressors are composite in nature, the present study was designed to determine the effects of the interaction of stressors in the induction of fluctuating dental asymmetry. Pregnant rats were assigned to one of six treatment groups and stressed with various combinations of heat, cold, noise and protein deprivation. The levels of fluctuating dental asymmetry were assessed and it was found that all protocols produced higher levels of asymmetry than found for control animals. Noise and reduced protein exhibited an additive effect and the interaction of stressors produced a reduction in litter size. Suggestions were offered for further research in this expanding field.
