A validated online questionnaire was distributed to final-year dental students at Universiti Teknologi MARA. The questionnaire utilized both scaled responses and closed-ended questions to gain data regarding students’ confidence levels in performing root canal treatment. : In this study, 93.4% of the students were confident in placing a rubber dam, 90.8% were confident in injecting local anesthesia and root canal irrigation. Procedures that were rated as least confident were access cavities and management of interappointment flare-ups. For the mean rate of self-confidence in performing RCT in the dentition, maxillary anterior teeth (4.24±0.63) ranked highest followed by mandibular premolars (4.11±0.72), whereas the least confidence was in treating maxillary molars (3.38±0.69). Higher scor...

Methodology: A simulation of a prepared root canal (conical frustum) of 12 mm length with an apical diameter of 0.40 mm following Protaper F4 apical preparation was created using three-dimensional (3D) CAD software. 3D simulated aspiration needles (EndoVac, micropores needle) and (mANP, 30G flat open-ended needle) were also created. The irrigation dynamics were evaluated through transient CFD simulations. In addition, the irrigation dynamics of mANP were also assessed at three different needle depths of insertion. Results: The EndoVac and mANP streamlines pattern showed irrigants able to reach the apical end. Both needle designs demonstrated negative static apical pressure. The mANP using an open-ended needle design revealed a higher average WSS magnitude in all three differen...

[1] One important component of the obturation is the placement of sealer. Conventional hand placement techniques of root canal sealers involve the use of reamers, absorbent paper points, lentulo spiral, and gutta-percha cones. [2] The limitations of all the techniques are the inability of the sealer to penetrate into canal Introduction: The aim of this study was to compare the effect between different levels of ultrasonic tip activation on the depth of epoxy resin-based sealer (AH plus) dentinal tubules penetration. Materials and Methods: Extracted single-rooted premolars (n = 60) were randomly allocated into three groups and instrumented following the same protocol. Group 1 (control), the sealer was mixed with 0.1% Rhodamine B dye and placed using size 20 K-file. In Group 2, the sealer was passively activated using ultrasonic tip (ISO 25) 10 s mesiodistally and buccolingually at 2 mm from the apex. In Group 3, the sealer was activated in a similar manner at 4 mm from the apex. Samples were sectioned horizontally at 2 mm, 4 mm, and 6 mm from the apex and analyzed using a stereomicroscope for tubular dentine sealer penetration. The cross-sectional area (μm 2) was measured with software to get the percentage of sealer penetration, and presences of voids were recorded. Results: Significant lesser percentage of sealer penetration into the dentinal tubules was observed between the control group and both the experimental groups (P = 0.00) at 2 mm, 4 mm, and 6 mm from the apex. There was no significant difference in the percentage of sealer penetration into the dentinal tubules between both the experimental groups (P > 0.05). The presence of voids between all groups was not statistically significant (P > 0.05). Conclusion: Passive ultrasonic activation of sealer placement resulted in deeper sealer penetration into the dentinal tubules even at a higher level of tip activation (4 mm).

It is rare and may be confused with a wide variety of diseases for example furuncle, pericoronitis in relation to the mandibular third molars, parotid fistula, preauricular sinuses, periapical and periodontal pathology, and many more. Patients might seek treatment from their physician as they are not aware of its odontogenic origin and these cases usually are misdiagnosed and leading to inappropriate treatment. Objective: To discuss the detailed management of two cases of extraoral draining sinus that were successfully treated. Case Reports: The first case was referred by the Department of Oral and Maxillofacial Surgery, for management of extraoral draining sinus originating from tooth 36. In the second case, the extraoral draining sinus is caused by pulpal necrosis of several mandibular anterior teeth. Intra-radicular microorganisms in infected root canal...
