This retrospective study aimed to assess the performance of posterior composite resin restorations (PCRRs) and evaluate the influence of patient-specific factors on restoration outcomes.
A total of 189 PCRRs were examined in 54 patients, with evaluations based on Modified USPHS criteria. Patient-specific factors were analyzed. Statistical analyses, including chi-square tests, independent samples t-tests, and ANOVA tests, were conducted.
Patients aged over 50 exhibited higher DMFT averages and a higher rate of unsuccessful restorations. Despite higher DMFT scores in females, gender doesn't significantly impact restoration outcomes. Secondary caries correlated with.plaque scores, significantly affecting restoration survival. Marginal adaptation, retention deficiencies, and secondary caries were primary causes of failure. Multi-surface restorations faced higher failure risk due to elevated plaque scores. Class-V restorations showed a higher failure rate, challenging the number of surfaces and longevity correlation.
This study identified key factors influencing posterior composite resin restorations-(PCRRs) in patients over 50, including higher DMFT averages and more unsuccessful restorations. No significant difference was found between brushing; frequency and DMFT rates, possibly due to the absence of non-brushers. Secondary caries; correlated with elevated plaque scores, impacting restoration survival. Primary causes of; failure included marginal adaptation issues, retention deficiencies, and secondary caries, with multi-surface restorations facing a higher risk. However, tooth vitality, beverage and acidic food consumption, and oral hygiene habits did not significantly affect PCRR outcomes.
Patient-specific factors significantly impact PCRRs' long-term performance. Dentists must tailor strategies, emphasizing regular monitoring and preventive measures for extended survival.
本回顾性研究旨在评估后牙复合树脂修复体（PCRRs）的性能，并评估患者特异性因素对修复结果的影响。
对54例患者的189个PCRRs进行检查，根据改良的美国公共卫生署（USPHS）标准进行评估。分析患者特异性因素。进行了包括卡方检验、独立样本t检验和方差分析在内的统计分析。
50岁以上患者的龋失补牙面（DMFT）平均值较高，修复失败率也较高。尽管女性的DMFT评分较高，但性别对修复结果没有显著影响。继发龋与菌斑评分相关，显著影响修复体的存留率。边缘适应性、固位不足和继发龋是失败的主要原因。多面修复体由于菌斑评分升高面临更高的失败风险。V类修复体显示出更高的失败率，对修复面数量与修复体寿命之间的相关性提出了挑战。
本研究确定了影响50岁以上患者后牙复合树脂修复体（PCRRs）的关键因素，包括较高的DMFT平均值和更多的修复失败。刷牙频率与DMFT率之间未发现显著差异，可能是因为没有不刷牙的患者。继发龋与菌斑评分升高相关，影响修复体的存留率。失败的主要原因包括边缘适应性问题、固位不足和继发龋，多面修复体面临更高的风险。然而，牙齿活力、饮料和酸性食物的摄入以及口腔卫生习惯对PCRRs的结果没有显著影响。
患者特异性因素显著影响PCRRs的长期性能。牙医必须制定相应策略，强调定期监测和预防措施以延长修复体使用寿命。
