    AIM: Online survey was conducted to investigate the state of undergraduate endodontic clinical training in Malaysian dental schools.

    METHODS: An online questionnaire and a cover letter were emailed to the deans of 13 Malaysian dental schools. The questionnaire covers various aspects of endodontic clinical training including teaching methods, endodontic clinical procedures, minimum requirements, clinical sessions and teaching staff.

    RESULTS: The response rate was 69%. Similarities in teaching methods were observed in all responding schools. All schools taught contemporary root canal treatment procedures, including the utilisation of radiograph and electronic apex locator for working length determination, the crown-down approach for canal preparation and the cold lateral compaction for obturation. Sodium hypochlorite solution and non-setting calcium hydroxide medicament were used in most dental schools. Variations were observed in terms of the number of clinical requirements, supervisor: student ratio, and availability of endodontic specialists. The use of engine-driven instruments was observed mainly in government-funded dental schools.

    CONCLUSIONS: The majority of dental schools in Malaysia are adopting the European Society Endodontology recommendation for undergraduate endodontic training, particularly in relation to the surveyed aspects. Most of the government-funded dental schools have progressed towards engaging contemporary endodontics with their increasing application of engine-driven Ni-Ti instruments and 3D imaging techniques. Appointments of full-time endodontic specialists would further enhance the quality of endodontic teaching and permit the utilisation of contemporary endodontic materials.

    The application of magnification devices in endodontics is mainly meant for visual enhancement and improved ergonomics. This is crucial especially when long hours are spent in a narrow operating space to treat obscure microanatomy. Nevertheless, application of magnification in endodontics has yet to be introduced into the mainstream practice due to various influences in behavioral patterns. By conducting an extensive literature search in the PubMed database, this narrative review paper depicts the present state of magnification devices, their applications within the endodontic practice, factors that influence their usage, the advantages, and shortcomings, as well as the significances of magnification in the field of endodontics. This review paper will encourage clinicians to employ magnification in their practice for improved outcome.

    This study aimed to evaluate and compare the frequency of microcracks and its severity at different root canal dentin locations, after preparation with thermomechanically heat-treated engine-driven nickel-titanium instruments. Forty mandibular premolars were assigned to four experimental groups (n = 10): ProTaper Next, ProTaper Gold, WaveOne Gold and Reciproc Blue. After pre-instrumentation micro-computed tomography scans, the root canals were prepared to size 25. Following post-instrumentation scans, pre- and post-instrumentation scanned images were analysed for the presence and extent of dentinal defects. A total of 56 500 cross-sectional images were obtained, showing that less than 2.3% with pre-existing dentinal microcracks. No new microcracks were identified during the post-instrumentation analyses. No significant association was found between the types of dentinal defects, file motions and sequences. Thermomechanically heat-treated rotary files did not induce the formation of new microcracks. There was also no association between the kinematic motions and sequences of the rotary instruments to the types of dentinal defects.
