Apical periodontitis (AP) is an inflammatory disease around the apex of a tooth root. Reported prevalence of AP ranges from 27% to 83% while the data about most post-Soviet countries are still missing. Knowing the prevalence of AP within a certain population helps to plan the treatment need and evaluate the success of endodontic interventions. We aimed to collect data about prevalence and determining factors of AP for the first time in Estonia.
The cross-sectional study included 6552 patients (age 35.5±19.2 years). Radiographic examination was applied to investigate the prevalence of AP and quality of endodontic treatment.
AP was diagnosed in 54.7% of subjects. Endodontically treated teeth were present in 58.2% of subjects. Periapical finding was present in 44.6% of endodontically treated and in 30.8% of untreated teeth. Out of 181,495 teeth, 52.7% were intact. AP was diagnosed in 6.3% of teeth, 6.9% of teeth were endodontically treated. Risk factors for AP included caries (OR = 2.30), male gender (OR = 1.44), too short (OR = 1.76) or too long root canal filling (OR = 2.51), root canal filling of low density (OR = 1.61) while not orthodontic appliance. Lower AP risk was associated with restoration of the tooth - filling (OR = 0.45), crown (OR = 0.34) and bridge (OR = 0.33).
AP is highly prevalent in Southern Estonian population. Most cases are associated with root canal-treated teeth. The overall quality of root canal fillings tends to be low, consistent with the mediocre outcome of treatment. Considerable efforts are required to improve the standards of endodontic treatment.
根尖周炎（AP）是一种发生在牙根尖周围的炎症性疾病。报道的AP患病率在27%至83%之间，而关于大多数后苏联国家的数据仍然缺失。了解特定人群中AP的患病率有助于规划治疗需求并评估牙髓治疗的成功率。我们旨在首次收集爱沙尼亚AP患病率及其决定因素的数据。
这项横断面研究纳入了6552名患者（年龄35.5±19.2岁）。采用影像学检查来调查AP的患病率和牙髓治疗质量。
54.7%的受试者被诊断为AP。58.2%的受试者有接受过牙髓治疗的牙齿。44.6%接受过牙髓治疗的牙齿和30.8%未治疗的牙齿存在根尖部病变。在181495颗牙齿中，52.7%是完好的。6.3%的牙齿被诊断为AP，6.9%的牙齿接受过牙髓治疗。AP的危险因素包括龋齿（比值比[OR]=2.30）、男性（OR=1.44）、根管充填过短（OR=1.76）或过长（OR=2.51）、根管充填密度低（OR=1.61），而不是正畸矫治器。较低的AP风险与牙齿修复有关——补牙（OR=0.45）、戴冠（OR=0.34）和镶桥（OR=0.33）。
AP在爱沙尼亚南部人群中高度流行。大多数病例与根管治疗过的牙齿有关。根管充填的总体质量往往较低，这与治疗效果一般相符。需要付出巨大努力来提高牙髓治疗的标准。
