: Dental occlusion and gingival recession have been studied over the past years especially because of the increasing incidence of occlusal interferences in young patients. The purpose of this pilot study is to investigate any association between occlusal dysfunctions and gingival recessions. Data on gingival phenotype and previous orthodontic treatment were also collected to assess any correlation with the presence of gingival recession. : Forty systemically healthy subjects, without signs of periodontitis and with gingival recessions, were included in the study. The following parameters were determined: location and extent of the gingival recession, gingival phenotype and functional occlusion by means of observing and registering the occlusal contacts in maximum intercuspation position, protrusive and lateral guidance. : Premolars were mostly affected in cases of working-side interferences during lateral guidance (71.19% of the affected teeth during left and 75% during right mandibular movements). The chi-squared exact test applied for the analysis of contingency tables revealed statistically significant associations between excursive interferences during lateral guidance and anterior guidance and the presence of gingival recession on the involved group of teeth. : The results suggest that most gingival recessions might be associated with working-side interferences, the highest number of gingival recessions being associated with active interferences during lateral guidance.
: 近年来,人们对牙齿咬合和牙龈退缩进行了研究,尤其是因为年轻患者中咬合干扰的发生率不断增加。本初步研究旨在调查咬合功能障碍与牙龈退缩之间是否存在关联。还收集了有关牙龈表型和以前正畸治疗的数据,以评估其与牙龈退缩存在的相关性。 : 本研究纳入了 40 名系统健康的受试者,他们没有牙周炎迹象且存在牙龈退缩。确定了以下参数:牙龈退缩的位置和程度、牙龈表型和功能咬合,方法是观察和记录在最大咬合位、前伸和侧方引导时的咬合接触。 : 在侧方引导时的工作侧干扰中,磨牙最常受到影响(左侧下颌运动时受影响的牙齿中有 71.19%,右侧下颌运动时受影响的牙齿中有 75%)。卡方精确检验应用于列联表分析表明,侧方引导和前伸引导时的非工作侧干扰与涉及的牙齿组中存在的牙龈退缩之间存在统计学显著关联。 : 结果表明,大多数牙龈退缩可能与工作侧干扰有关,在侧方引导时主动干扰与最多数量的牙龈退缩相关。
