Despite numerous studies on the prevalence of apical periodontitis (AP) and endodontic treatment in diverse geographical populations, there are currently no data on the prevalence of these conditions in populations of adults native to Kosovo. Therefore, little is known about how widespread these conditions are, and whether there is any correlation between root canal treatment and AP. The purpose of our research was to address this anomaly by investigating AP and endodontic treatment in an adult Kosovar population based on radiographic examination.
The sample used for this study consisted of randomly selected individuals referred to the University Dentistry Clinical Center of Kosovo in the years 2006-2007. Orthopantomographs of 193 patients were evaluated. The periapical status of all teeth (with the exception of third molars) was examined according to Ørstavik's Periapical Index. The quality of the root canal filling was rated as 'adequate' or 'inadequate' based on whether all canals were filled, the depth of fill relative to the radiographic apex and the quality of compaction (absence/presence of voids). Data were analyzed statistically using the Chi-square test and calculation of odds ratios.
Out of 4131 examined teeth, the prevalence of apical periodontitis (AP) and endodontic treatment was 12.3% and 2.3%, respectively. Of 95 endodontically-treated teeth, 46.3% were associated with AP. The prevalence of AP increased with age. The prevalence in subjects aged over 60 years old (20.2%) was higher than in other age groups. A statistically significant difference was found for the frequency of endodontically-treated teeth associated with AP in the 40-49 year age group (P < 0.001). Of some concern was the discovery that only 30.5% of the endodontically-treated teeth examined met the criteria of an acceptable root canal filling. Inadequately root-filled teeth were associated with an increased AP risk.
The prevalence of AP and the frequency of endodontically-treated teeth with AP in this Kosovar population are higher than those found in other countries. Inadequate root canal fillings were associated with an increased prevalence of AP.
尽管有许多关于根尖周病（AP）和牙髓治疗在不同地理人群中的流行率的研究，但目前还没有关于这些人群中成年人的患病率的数据。因此，人们对这些疾病的流行程度知之甚少，也不知道根管治疗和 AP 之间是否存在任何关联。我们的研究目的是通过基于影像学检查来研究科索沃成年人的 AP 和牙髓治疗，以解决这一异常情况。
本研究的样本包括 2006-2007 年随机选择到科索沃大学牙科学院就诊的个体。评估了 193 名患者的口腔全景片。根据 Ørstavik 的根尖周指数，检查了所有牙齿（除第三磨牙外）的根尖周状况。根据所有根管是否被填充、相对于根尖的填充深度和压实质量（有无空隙），将根管填充质量评为“充分”或“不充分”。使用卡方检验和计算比值比进行统计学分析。
在 4131 颗检查的牙齿中，根尖周病（AP）和牙髓治疗的患病率分别为 12.3%和 2.3%。在 95 颗接受牙髓治疗的牙齿中，46.3%与 AP 有关。AP 的患病率随年龄增长而增加。60 岁以上人群的患病率（20.2%）高于其他年龄组。在 40-49 岁年龄组中，AP 相关的牙髓治疗牙的频率存在统计学显著差异（P<0.001）。令人担忧的是，仅 30.5%的接受检查的牙髓治疗牙符合可接受的根管填充标准。根管填充不足的牙齿与 AP 风险增加有关。
在这个科索沃人群中，AP 的患病率和 AP 相关的牙髓治疗牙的频率都高于其他国家。根管填充不足与 AP 患病率增加有关。
