Abstract
BackgroundThe aim of the present study was to compare clinically the incidence of postoperative pain after endodontic treatment using the Reciproc System, taking into account the operator’s experience.Material and MethodsOne hundred patients scheduled for routine endodontic treatment were enrolled in this study. Endodontic treatment was carried out in a single visit by undergraduate and postgraduate students. The chemomechanical preparation of root canals was performed with Reciproc instruments. Pretreatment and postoperative pain was recorded using a visual analogue scale (VAS). Postoperative pain and the need for analgesic consumption were assessed at 4, 8, 16, 24, 48 and 72 hours post-treatment. The data were analyzed using the Mann–Whitney U and Chi-Square test, and the significance was set at P<0.05.ResultsThe mean value of pain after root canal treatment was 1.13±1.94 and 1.91±2.07 on a VAS between 0 and 10 in treatments performed by undergraduate and postgraduate students, respectively. There was a significant difference in the incidence of postoperative pain between the two groups (P<0.05).ConclusionsThe prevalence of postoperative pain was high in the treatments performed by postgraduate students in comparison with undergraduate students. This suggests that operator experience has an influence on the prevalence of postoperative pain after root canal treatment. Key words:Post-endodontic pain, root canal treatment, reciprocating systems, Expert operators Inexperienced operators.
Highlights
Root canal treatment is a common procedure that aims to preserve the tooth by treating diseases of the dental pulp and periradicular region [1]
The Mann–Whitney test showed no significant difference in age distribution between the two groups (P > .05). -Pretreatment pain, Post-treatment pain and intake of analgesics The mean baseline pretreatment pain in the undergraduate student group and the Endodontic Postgraduate student group was 1.99±3.20 and 2.35±2.75, respectively, with no significant differences (P > .05)
We found that patients treated by postgraduate students had a significantly higher prevalence of postoperative pain than those treated by undergraduate students (P = 0.01)
Summary
Root canal treatment is a common procedure that aims to preserve the tooth by treating diseases of the dental pulp and periradicular region [1]. Undergraduate endodontic teaching has made significant headway in educational approaches to knowledge, techniques, and materials These advances have improved the ability of dental students to diagnose and treat pulpal and periradicular diseases [2]. Post-endodontic pain has been investigated in several studies [13,19,20,21]; there is little knowledge about the incidence of postoperative pain after treatment with reciprocating instruments. The purpose of this prospective clinical study was to compare the incidence of postoperative pain after root canal treatment performed by undergraduate and postgraduate students using the Reciproc system. Conclusions: The prevalence of postoperative pain was high in the treatments performed by postgraduate students in comparison with undergraduate students This suggests that operator experience has an influence on the prevalence of postoperative pain after root canal treatment
