The objective of this study was to assess the quality of post and core restorations carried out by general dentists in the Hail region of Saudi Arabia using periapical radiographs. Additionally, the assessment included the examination of periapical lesions.
A comprehensive analysis was conducted on 301 periapical digital radiographs to assess various factors including the type of post, type of coronal restoration, post length in relation to crown and root length, presence of any abnormalities in the post space, condition of the remaining gutta-percha (GP), gap between the end of the post and the GP, and the presence of apical lesions. Analysis was conducted to determine the frequency distribution and cross-tabulation of the variables.
Prefabricated metallic posts were most commonly used (62.1%), followed by metal posts which were found in 28.9% of the cases, and fiber posts which were used in 9.0% of the cases. The length of the posts in relation to the tooth were 2:1 in 32.6%, followed by 1:1 (27.9%) and 1:2 (23.6%). Parallel posts were used in 54.2% of cases, while the remaining 45.8% used tapered posts. Smooth posts were utilized in 77.1% of the cases, while serrated posts were utilized in 22.9%. Approximately 54.2% of the cases exhibited remaining GP of more than 5 mm, whereas 35.2% demonstrated adequate GP between 3-5 mm and 8.0% with remaining GP less than 3 mm. According to the study's findings, 65.1% of the samples under investigation had full coverage indirect restorations placed.
It was found that the post and core procedures' quality was comparable to earlier epidemiological studies. However, a significant proportion of posts were deemed to have poor technical quality, and apical periodontitis was seen in slightly more than one-third of the cases.
本研究的目的是使用根尖片评估沙特阿拉伯海勒地区普通牙医进行的桩核修复体的质量。此外，评估还包括对根尖病变的检查。
对301张根尖数字化X线片进行了全面分析，以评估各种因素，包括桩的类型、冠修复体的类型、桩长度与冠和根长度的关系、桩道内是否存在任何异常、剩余牙胶的状况、桩末端与牙胶之间的间隙以及根尖病变的存在情况。进行分析以确定变量的频率分布和交叉表。
最常用的是预成金属桩（62.1%），其次是金属桩，占28.9%的病例，纤维桩占9.0%的病例。桩长度与牙齿的比例为2:1的占32.6%，其次是1:1（27.9%）和1:2（23.6%）。54.2%的病例使用平行桩，其余45.8%使用锥形桩。77.1%的病例使用光滑桩，22.9%使用锯齿桩。约54.2%的病例显示剩余牙胶超过5mm，而35.2%显示牙胶在3 - 5mm之间合适，8.0%的剩余牙胶小于3mm。根据研究结果，65.1%的受调查样本放置了全冠间接修复体。
发现桩核修复程序的质量与早期流行病学研究相当。然而，相当一部分桩被认为技术质量较差，并且在略多于三分之一的病例中发现了根尖周炎。
