“…Hence, the working length is a very significant aspect in evaluating the excellence of endodontic treatment. Ideally, it is believed that the working length seems to be 1–2 mm from the radiographic apex [ 11 , 12 ]. The inter-appointment medicaments have been promoted to deliver an uninterrupted quantity of antimicrobial agents that limits the growth of bacteria and blocks bacterial multiplication [ 13 ].…”

A contemporary knowledge of root canal treatment (RCT) is a prerequisite for a successful outcome. Studies observed that General Dental Practitioners (GDPs) were not abreast of current endodontic knowledge due to a lack of continuing dental education, not following the treatment protocols that they had learned in their undergraduate program, and overlooking the evidence-based current endodontic practices. Therefore, this study was intended to assess the awareness, attitude, and clinical endodontic practices among General Dental Practitioners in Saudi Arabia. This cross-sectional questionnaire-based study was conducted among all 312 GDPs working in Saudi Arabia. The questionnaire consisted of socio-demographic details and 23 questions regarding current endodontic practices. The collected data was analyzed using the SPSS Version 21 (Chicago, IL, USA). The chi-square test was applied to explore the influence of gender, workplace, and the years of professional activity on the materials and techniques employed in the RCT procedure. The study results showed that of all respondents, 159(51.0%) were males, 153(49.0%) were females, and 286(91.7%) were Saudi nationals. Most of the GDPs, i.e., 204(65.4%) practiced in private hospitals or clinics whereas 108(34.6%) practiced in Government hospitals. Root canal treatment on all teeth had been performed by 196(62%) of the practitioners. Association of gender with demographic details and endodontic practices revealed a statistically significant difference between both genders with respect to region, nationality, type of RCT treated on the tooth, and the technique used to measure the working length (p < 0.05). Furthermore, years of professional experience and workplace significantly affect endodontic practices (p < 0.05). This study concluded that most of the general dental practitioners complied with quality standard guidelines showing a positive attitude toward endodontic practices. Furthermore, irrespective of gender, most of the steps in endodontic procedures revealed a significant association with years of professional experience and the workplace.

Background To investigate the effect of silver diamine fluoride (SDF) application and activation on the bond strength of gutta-percha to dentin and resin bonded post to dentin. Methods Thirty-six human premolar teeth were used. The coronal part tooth was removed, and endodontic mechanical preparation was performed for all the teeth. The teeth were divided according to final rinse protocol (n = 9) as follows: Control group; no SDF application, SDF/NA; 38% SDF as a final rinse with no activation, SDF/MDA; 38% SDF as a final rinse with manual dynamic activation and SDF/US; 38% SDF as a final rinse with ultrasonic activation. Root canal obturation using lateral condensation technique followed by fiber post insertion after 48 h in the root canal after corresponding preparations. The roots were cut with a low-speed precision saw creating 2 mm thickness sections. A total of 4 sections were obtained from each tooth, 2 coronal specimens (with post) and 2 apical specimens (with Gutta percha). Each specimen was subjected to push-out bond strength test with a universal testing machine. Data were analyzed using two-way ANOVA. Results The Push-out bond strength at the apical root section was significantly higher in SDF/MDA and SDF/US groups compared to control group. While for the coronal part, all SDF treated specimen showed reduced Push-out bond strength. Conclusion SDF application as final rinse may reduce the bonding performance between fiber post and dentine. Activation with manual and ultrasonic methods improved the bond strength at the apical root section.

“…In some cases of endodontically treated teeth, intra-canal posts are considered essential in order to enhance the final restoration retention. Compared to cast metal and core systems, fiber posts became more usable due to their better esthetics, closer elastic modulus to that of dentin, and more uniform stress distribution (1)(2)(3).…”

“…Debonding of the fiber posts at the adhesive resin-dentin junction is considered to be their most common failure reason, which is thought out to be a sequel of the thick smear layer and debris covering the root surface formed during post space preparation (1)(2)(3) .…”

Background;The smear layer is considered an obstacle limiting the penetration of adhesive types of cement into the dentinal tubules, thus adversely affecting the bond strength of the fiber posts. Objective;The purpose of this study was to assess the effect of ultra-sonic activation on the bond strength of fiber posts, cemented with self-adhesive cement to the root dentin.Methods; A total of 18 recently extracted single rooted premolars were selected. The root canals were prepared using ProTaper rotary, samples were obturated with Protaper universal gutta percha points. Post space was prepared using gates glidden drills, specimens were randomly divided into two groups of n=9 according to the irrigation application techniques; Group 1: conventional syringe, Group 2: ultra-sonic activation. Posts were cemented using Rely X Unicem2, bond strength was determined by pull out test.Results; A statistically significant higher mean value was recorded in Group 2 compared to Group 1.Conclusions; Ultrasonic activation can aid the irrigation with 2.6% NaOCl followed by 17% EDTA in smear layer removal, contributing in a triad way of cleaning of the root canal system and thus promoting the bond strength of fiber posts.
