To study the reasons given by a representative sample of Danish general dental practitioners (GDPs) for undertaking root canal treatment and, to investigate their confidence in performing root canal treatment on molar teeth.
A questionnaire was sent to 600 Danish GDPs randomly selected from the roster of the Danish Dental Association. They were asked to recall various factors about their experience of the last root filling they completed, including the reason for treatment and the pulp diagnosis. Self-assessments on 100-mm visual analogue scales (VAS) were reported concerning the confidence in performing root canal treatment of a molar. End-point definitions were 'very easy' (0) and 'very difficult' (100), respectively. Time reports of molar treatments were given in categorized groups.
The most frequent reason for performing root canal treatment was caries within the tooth involved (55%). The majority of treatments involved teeth with vital pulps (54%). Retreatments were carried out in 2% of the cases. The confidence in performing root canal treatment varied but was relatively high, expressed as VAS-values below 50. The creation of an aseptic working field was regarded as the most difficult procedure followed by root canal preparation. Fifty-six percent of the responders stated a time frame of 46-75 min to complete root filling in a molar tooth.
Root canal treatment in Denmark was reported to be undertaken most often because of caries. Treatment was typically performed in molar teeth with vital pulp. Even though apical periodontitis was frequently noted in root filled teeth, retreatments were rare. From a subjective perspective root canal treatment was not considered to be very difficult and was carried out relatively rapidly.
研究丹麦普通牙科医生(GDPs)代表性样本进行根管治疗的原因,并调查他们对磨牙进行根管治疗的信心。
向从丹麦牙科协会名册中随机选取的600名丹麦GDPs发送问卷。要求他们回忆关于他们完成的最后一次根管充填的各种因素,包括治疗原因和牙髓诊断。报告了关于对磨牙进行根管治疗信心的100毫米视觉模拟量表(VAS)的自我评估。终点定义分别为“非常容易”(0)和“非常困难”(100)。磨牙治疗的时间报告按分类组给出。
进行根管治疗最常见的原因是患牙龋坏(55%)。大多数治疗涉及牙髓活力正常的牙齿(54%)。2%的病例进行了再治疗。进行根管治疗的信心各不相同,但相对较高,以低于50的VAS值表示。创建无菌工作区被认为是最困难的步骤,其次是根管预备。56%的受访者表示完成一颗磨牙根管充填的时间框架为46至75分钟。
据报告,丹麦根管治疗最常因龋齿进行。治疗通常在牙髓活力正常的磨牙中进行。尽管根管充填后的牙齿根尖周炎很常见,但再治疗很少见。从主观角度来看,根管治疗并不被认为非常困难,而且进行得相对较快。
