In 46 non-patients and 46 patients, the authors examined the presence (+) and absence (-) of canine tooth guidance (CG), i.e. dynamic dental articulation events in contrast to static dental occlusion events. During a right and a left laterotrusion of the mandible, the number of simple, mutually exclusive and exhaustive tooth guidance events (possibilities) was four. In addition, the authors examined the associations between temporomandibular joint (TMJ) sounds and canine guidance events. In non-patients, CG+ was relatively infrequent (30%), and CG- was relatively frequent (70%). In patients, CG+ was relatively infrequent (22%), and CG- was relatively frequent (78%). In both non-patients and patients, bilateral CG+ was rather infrequent (15%). In both non-patients and patients with the presence of TMJ sounds, CG+ was relatively infrequent (38%) while CG- was relatively frequent (61%). In non-patients as well as patients, no evidence was found that distal CG+ (putative lateral retrusive guidance) was associated with ipsilateral TMJ sounds (relative risk = 0%), nor that the association between mesial CG+ (putative lateral protrusive guidance) and ipsilateral TMJ sounds was beyond that of mere chance (relative risk = 50%).
在46名非患者和46名患者中，作者检查了犬牙引导（CG）的存在（+）和缺失（-）情况，即与静态牙合关系事件相对的动态牙合关节事件。在下颌骨左右侧方运动过程中，简单、相互排斥且详尽无遗的牙引导事件（可能性）数量为4种。此外，作者还研究了颞下颌关节（TMJ）弹响与犬牙引导事件之间的关联。在非患者中，CG+相对少见（30%），而CG-相对常见（70%）。在患者中，CG+相对少见（22%），CG-相对常见（78%）。在非患者和患者中，双侧CG+都相当少见（15%）。在有TMJ弹响的非患者和患者中，CG+相对少见（38%），而CG-相对常见（61%）。在非患者以及患者中，未发现远中CG+（假定的侧方后退引导）与同侧TMJ弹响有关联（相对风险=0%），也未发现近中CG+（假定的侧方前伸引导）与同侧TMJ弹响之间的关联超出偶然范畴（相对风险=50%）。
