Periodontal disease of equine cheek teeth is common and may lead to tooth loss if left untreated. Limited information is available comparing the effectiveness of treatment methods. The objective of this study was to retrospectively compare the effectiveness of 4 commonly used treatments in reducing periodontal pocket depth (in addition to routine dental treatment and occlusal equilibration). The 4 treatments compared were (1) removal of feed material, lavaging the pocket with dilute chlorhexidine, and then rinsing the mouth with chlorhexidine-containing mouthwash (CL); (2) CL plus placement of metronidazole into the pocket (M); (3) M plus the addition of polyvinyl siloxane temporary filling over the diastema (PVS); and (4) diastema widening to increase the interdental space, then PVS (DW). Pocket measurements were compared before and 2 to 6 months after treatment. Treatment groups CL, M, and PVS showed statistically significant reductions in pocket depth following treatment. The mean pocket depth reduction was the greatest in the DW group (and this was the only group with no cases having an increase in pocket depth), but this was not significant due to the small sample size. Additional analysis to compare effectiveness revealed a confounding effect of initial pocket depth. After accounting for this, DW was associated with smaller improvements than the other treatments, however, this was also based on a small sample size. After accounting for confounders, differences between treatments CL, M and PVS were not found to be significant, although all were associated with statistically significant reductions in pocket depth.
马颊齿的牙周病很常见，如果不治疗可能会导致牙齿脱落。关于比较治疗方法有效性的信息有限。本研究的目的是回顾性比较4种常用治疗方法在减少牙周袋深度方面的有效性（除常规牙科治疗和咬合平衡外）。所比较的4种治疗方法为：（1）清除饲料残渣，用稀释的洗必泰冲洗牙周袋，然后用含洗必泰的漱口水漱口（CL）；（2）CL加在牙周袋内放置甲硝唑（M）；（3）M加在牙间隙上添加聚乙烯基硅氧烷临时充填物（PVS）；（4）扩大牙间隙以增加牙间隙宽度，然后进行PVS（DW）。在治疗前以及治疗后2至6个月比较牙周袋测量值。治疗组CL、M和PVS在治疗后牙周袋深度有统计学意义的降低。DW组的平均牙周袋深度降低最大（且这是唯一没有牙周袋深度增加病例的组），但由于样本量小，差异无统计学意义。比较有效性的进一步分析显示初始牙周袋深度有混杂效应。考虑到这一点后，DW组的改善程度小于其他治疗方法，不过这也是基于小样本量。在考虑混杂因素后，未发现治疗组CL、M和PVS之间的差异有统计学意义，尽管所有组的牙周袋深度均有统计学意义的降低。
