Post and core procedures are important clinical methods in routine dental practice. The present research aimed to radiographically assess the quality of post seating performed by undergraduate students at the College of Dentistry, Jazan University.
A total of 343 periapical X-rays of cemented posts (170 from males and 173 from females) were assessed. The assessment covered tooth type, arch, gender, type of post, length of post in relation to the crown and root lengths, the presence of any abnormality in post space, status of the remaining gutta-percha (GP), and the presence or absence of spaces between the end of post and GP. Data were analyzed using the Statistical Package for the Social Sciences (SPSS) program (version 21), and associations between variables were determined using chi-squared or Fisher's exact tests.
Maxillary teeth were the most frequently restored with posts, and the majority (41%) comprised incisors. Similarly, glass fiber post (69%) and taper-shaped posts (86%) were the most used posts. The majority of posts (81.6%) featured a width one-thirds that of the root. Lengths of posts were twice (58%) or equal to (51%) crown and root length respectively. More than 55% of cases presented 3 to 5 mm of GP at their apical portion, and 29% reached more than 5 mm. Approximately 5 to 8% of assessed cases revealed widening of periodontal ligaments, presence of periapical pathologies, and deviation of posts from the canal wall. Most cases (75%) showed the absence of space between GP and the post end.
Qualities of assessed post and core restorations conducted by the 6th year dental students were clinically acceptable.
Periodic evaluation to determine the quality of delivered treatments is a vital cue for health service authorities. This evaluation will improve quality of services and treatments provided by dental students to their patients under the supervision of the faculty. Results obtained will also provide authorities with a clear feedback about academic infrastructure.
桩核修复程序是常规牙科临床实践中的重要方法。本研究旨在通过影像学评估吉赞大学牙科学院本科生进行的桩就位质量。
共评估了343张粘结桩的根尖片（男性170张，女性173张）。评估内容包括牙齿类型、牙弓、性别、桩的类型、桩相对于冠部和根部长度的长度、桩道空间是否存在任何异常、剩余牙胶尖（GP）的状况以及桩末端与GP之间是否存在间隙。使用社会科学统计软件包（SPSS）程序（版本21）进行数据分析，并使用卡方检验或费舍尔精确检验确定变量之间的关联。
上颌牙是最常进行桩修复的牙齿，其中大多数（41%）为切牙。同样，玻璃纤维桩（69%）和锥形桩（86%）是最常用的桩。大多数桩（81.6%）的宽度为牙根宽度的三分之一。桩的长度分别是冠部长度的两倍（58%）或与冠部和根部长度相等（51%）。超过55%的病例根尖部有3至5毫米的牙胶尖，29%的病例牙胶尖长度超过5毫米。约5%至8%的评估病例显示牙周膜增宽、根尖病变以及桩偏离根管壁。大多数病例（75%）显示牙胶尖与桩末端之间无间隙。
六年级牙科学生进行的评估桩核修复质量在临床上是可以接受的。
定期评估以确定所提供治疗的质量是卫生服务当局的重要提示。该评估将提高牙科学生在教师监督下为患者提供的服务和治疗质量。获得的结果还将为当局提供有关学术基础设施的明确反馈。
