<p><strong><em>Background :</em></strong><em> There are some factors can cause endodontic failure such as inadequate in cleaning or shaping step, non hermetic obturation, or poor restoration, which can cause bacteria multiply. <strong>Purpose :</strong> To report the management of endodontic failure with nonsurgical treatment. <strong>Case :</strong> 46-year-old woman came to Airlangga Dental Hospital Conservative Dentistry Department to treat her upper right tooth which show symptomatic pain in the last 2 weeks. The tooth has been treated and crowned with porcelain fused to metal about 10 years ago. Clinical examination show the presence of fistula on premolar buccal gingiva, react to percussion.  Radiographic examination show not hermetic obturation in one root canal and radiolucency in the periapical area. The diagnosis for maxillary first premolar is previously treated tooth with chronic periapical abscess.. <strong>Treatment :</strong> Crown and post was removed from the tooth, and endodontic retreatment was done. Follow up 6 months after the retreatment show no reaction to percussion, and radiographic examination show no enlargement periapical lesion. <strong>Conclusion :</strong> Nonsurgical endodontic retreatment always become the first choice to resolve endodontic failure for previously treated tooth.</em></p><p><strong><em>Keywords :</em></strong><em> endodontic failure, maxillary first premolar, nonsurgical endodontic retreatment</em></p><p><strong><em>Correspondence:</em></strong><em> Yongki Hadinata W., drg.

Objective: To show the consequence of two thicknesses of ceramic on the polymerization of resin cement light cured when three different lithium silicate ceramics were used. Materials and Methods: 42 ceramic slices were prepared from three types of ceramics, Emax CAD, Celtra Duo CAD and Vita suprinity CAD (n=14). They were further divided into two subgroups according to thicknesses into sub group thickness 0.5mm and sub group thickness 1mm (n=7). Teflon moulds were fabricated with specific dimensions, where the ceramic disc was placed followed by light cured resin cement Bisco choice 2 veneer and a glass slab with finger pressure applied. Curing with Ascent® PX LED light cure unit for 20 seconds took place, where the tip placed over the ceramic sample directly. Cement film was then separated from the ceramic disk and subjected to analysis by Fourier Transform Infrared Spectroscope. Uncured cement samples were also subjected to analysis. Results: Celtra DUO CAD ceramic showed higher degree of polymerization that of Emax and Vita suprinity while the difference between Emax and Suprinity on the degree of polymerization was not significant. Also, ceramic thicknesses had a significant effect on the degree of polymerization of the resin cement. Conclusion: Thickness of ceramics up to 1mm affects the polymerization of resin cement significantly.

Background: Dental schools are considered to be a very stressful environment; the stress levels of dental students are higher than those of the general population. The aim of this study was to assess the level of stress among dental students while performing specific dental procedures. Methods: A survey was conducted among 257 participants. We used an original questionnaire, which consisted of 14 questions assigned to three categories: I—Diagnosis, II—Caries Treatment, and III—Endodontic Treatment. Each participant marked their perceived level of stress during the performed dental treatment procedures. The scale included values of 0–6, where 0 indicates no stress, while 6 indicates high stress. Results: Third- (p=0.006) and fourth-year (p=0.009) women were characterized by a higher level of perceived stress during dental procedures related to caries treatment. Caries treatment procedures were the most stressful for 18.3% of third-year students, 4.3% of fourth-year students, and 3.2% of fifth-year students. Furthermore, 63.4% of third-year students, 47.3% of fourth-year students, and 17.2% of fifth-year students indicated that they felt a high level of stress when performing endodontic procedures. Conclusion: Third- and fourth-year female students are characterized by a higher level of stress during caries and endodontic treatment procedures. The most stressful treatments for participants were endodontic treatment procedures.
