The purpose of this study was to evaluate the association between signs of trauma from occlusion, severity of periodontitis and radiographic record of bone support. The maxillary first molars of 300 individuals were independently evaluated by two examiners for signs of trauma from occlusion, pattern or occlusal contacts and severity of periodontitis. Each site was also evaluated radiographically by an independent third examiner. The results indicated that: teeth with either bidigital mobility, functional mobility, a widened periodontal ligament space or the presence of radiographically visible calculus had a deeper probing depth, more loss of clinical attachment and less radiographic osseous support than teeth without these findings, teeth with occlusal contacts in centric relation, working, nonworking or protrusive positions did not exhibit any greater severity of periodontitis than teeth without these contacts, teeth with both functional mobility and radiographically widened periodontal ligament space had deeper probing depth, more clinical attachment loss and less radiographic osseous support than teeth without these findings and given equal clinical attachment levels, teeth with evidence of functional mobility and a widened periodontal ligament space had less radiographic osseous support than teeth without these findings.
本研究的目的是评估咬合创伤迹象、牙周炎严重程度与骨支持的影像学记录之间的关联。300名个体的上颌第一磨牙由两名检查者独立评估咬合创伤迹象、咬合接触模式或情况以及牙周炎的严重程度。每个部位还由一名独立的第三位检查者进行影像学评估。结果表明：与没有这些表现的牙齿相比，具有双侧指压移动度、功能动度、牙周膜间隙增宽或存在影像学可见牙石的牙齿有更深的探诊深度、更多的临床附着丧失和更少的影像学骨支持；在正中关系、工作侧、非工作侧或前伸位有咬合接触的牙齿，与没有这些接触的牙齿相比，并未表现出更严重的牙周炎；与没有这些表现的牙齿相比，具有功能动度且影像学显示牙周膜间隙增宽的牙齿有更深的探诊深度、更多的临床附着丧失和更少的影像学骨支持；在临床附着水平相同的情况下，有功能动度和牙周膜间隙增宽证据的牙齿比没有这些表现的牙齿有更少的影像学骨支持。
