To investigate the quality of root fillings and coronal restorations and their association with periapical status in an adult Turkish subpopulation.
A total of 400 subjects were examined. Panoramic radiographs of all participants and additional periapical radiographs of affected teeth were processed. The frequency of root canal treatment and the periapical status of all root filled teeth were evaluated. The relationship between the radiographic quality of root fillings and coronal restorations was examined by chi-squared statistical analysis.
A total of 9460 teeth were examined. The total number of root filled teeth was 890 (9.39%), and 658 (73.9%) had apical periodontitis (AP). There was a significant correlation between the presence of periapical pathology and inadequate root canal fillings (P<.05). Presence of AP in root filled teeth was associated with inadequate adaptation of the filling (OR=1.097; P=0.54), and with poor radiographic quality of the coronal restoration (OR=0.91; P=0.70), and with poor radiographic quality of the filling restoration (OR=0.97; P=0.92). Only 24.5% of the root fillings were adequate. The highest percentage of root fillings was found in maxillary right first molars (6.9%).
The results demonstrate a low prevalence of root-filled teeth and poor quality of coronal restorations and root fillings consistent with a high prevalence of apical periodontitis in a Turkish subpopulation.
在土耳其成年亚人群体中，调查根管充填和冠修复的质量及其与根尖周状况的关联。
共检查了400名受试者。处理了所有参与者的全景X线片以及患牙的额外根尖X线片。评估根管治疗的频率以及所有根管充填牙齿的根尖周状况。通过卡方统计分析检查根管充填和冠修复的影像学质量之间的关系。
共检查了9460颗牙齿。根管充填牙齿的总数为890颗（9.39%），其中658颗（73.9%）患有根尖周炎（AP）。根尖周病变的存在与根管充填不充分之间存在显著相关性（P<0.05）。根管充填牙齿中存在AP与充填物贴合不充分相关（OR=1.097；P=0.54），与冠修复的影像学质量差相关（OR=0.91；P=0.70），与充填修复的影像学质量差相关（OR=0.97；P=0.92）。只有24.5%的根管充填是充分的。根管充填比例最高的是上颌右侧第一磨牙（6.9%）。
结果表明，在土耳其亚人群体中，根管充填牙齿的患病率较低，冠修复和根管充填质量较差，这与根尖周炎的高患病率一致。
