To compare the frequency of apical periodontitis (AP) in non-endodontically treated teeth restored with full coverage crowns, amalgam and resin composite fillings, and to disclose the association of type and quality of coronal restoration with periapical disease.
The cross-sectional study involved 597 subjects who attended the Dental Clinic of the Clinical Hospital Centre, Rijeka, Croatia for the first time. Data were collected by means of a clinical and radiological survey. The following data were recorded for all permanently restored non-endodontically treated teeth: the type, the quality of coronal restoration according to clinical and radiographic criteria for marginal integrity as well as the recurrent caries presence, periapical status and marginal bone loss. Chi-square tests were used to analyze the difference in periapical status regarding the type and the quality of restoration. The multivariate logistic regression analysis was used to assess the effect of explanatory tooth-specific variables on periapical status.
There was no significant difference in the proportion of AP with regards to the type and material of adequate quality coronal restorations (χ=5.000, P=0.082). The regression analysis revealed significant positive associations with outcome variable (AP) for crowns (OR=3.39; P<0.001), recurrent caries (OR=4.67; P<0.001) and premolar teeth (OR=1.73; P=0.002).
If the quality of restorations is adequate, there is no difference in the periapical status of non-endodontically treated teeth regarding the type and material of coronal restoration.
比较用全冠、汞合金和树脂复合体充填修复的未经牙髓治疗牙齿的根尖周炎（AP）发生率，并揭示冠部修复体的类型和质量与根尖周疾病之间的关联。
这项横断面研究纳入了597名首次前往克罗地亚里耶卡临床医院中心牙科诊所就诊的受试者。通过临床和放射学检查收集数据。记录所有永久性修复的未经牙髓治疗牙齿的以下数据：修复体类型、根据边缘完整性的临床和影像学标准评估的冠部修复体质量、继发龋的存在情况、根尖周状况和边缘骨丧失情况。采用卡方检验分析根尖周状况在修复体类型和质量方面的差异。采用多因素逻辑回归分析评估解释性牙齿特异性变量对根尖周状况的影响。
在质量合格的冠部修复体的类型和材料方面，AP的比例没有显著差异（χ=5.000，P=0.082）。回归分析显示，全冠（OR=3.39；P<0.001）、继发龋（OR=4.67；P<0.001）和前磨牙（OR=1.73；P=0.002）与结局变量（AP）之间存在显著正相关。
如果修复体质量合格，未经牙髓治疗牙齿的根尖周状况在冠部修复体的类型和材料方面没有差异。
