在本研究中，观察了饲喂饲料的米鼠出生后6天至15周的牙周综合征，以及饲喂高蔗糖饲料的米鼠从断奶(出生后3周)一直到出生后17周的情况。饲喂饲料的大鼠在萌出的后牙上可见早期大量的菌斑堆积，并伴有PMN渗出物，PMN渗出渗入牙龈上皮和固有层。在这组动物中，炎性和吸收改变在跨隔纤维区和肺泡顶很少见。在饲喂700日粮的大鼠中，可以看到类似的细菌菌斑聚集和PMN浸润的模式。在以后的时间段，这种PMN浸润物通常被看到通过跨隔纤维区延伸到牙槽顶，在那里有明显的破骨细胞活动。炎性浸润物的这种根尖延伸与上覆牙龈上皮的溃烂有关。
In this study on the periodontal syndrome in the rice rat, observations were made on rice rats fed stock diet and followed from six days to fifteen weeks after birth, and on rice rats fed a high sucrose diet (Diet 700) from weaning (3 weeks after birth) and followed to seventeen weeks after birth.In rats fed stock diet, early massive accumulations of bacterial plaque were seen on erupting posterior teeth with an underlying PMN exudate and a PMN infiltrate within the gingival epithelium and lamina propria. Inflammatory and resorptive changes were rarely seen in the transeptal fiber area and alveolar crest in this group of animals.In rats fed diet 700, similar patterns of bacterial plaque accumulations and PMN infiltrations were seen. At later time periods, this PMN infiltrate was commonly seen to extend through the transseptal fiber area to the alveolar crest where marked osteoclastic activity was noted. Such apical extension of the inflammatory infiltrate was associated with ulceration of the overlying gingival epithelium.
