Title: MTA Obturation    
Speaker: Dr Josephine Tay Chiew Xsia
Date: Wednesday 11 May 2022


MTA, a.k.a bioceramics, is one of the best inventions in endodontics. It’s known for its excellent biocompatibility, hermetic seal, and antimicrobial properties, used in an array of clinical applications. More commonly in perforation repairs, root-end surgeries, regenerative endodontics, and vital pulp therapies. Its use as root canal obturating material, in the form of sealers and cements per se, is gaining popularity and momentum. Here, we will discuss the whys, dos, and don’ts of MTA applications in obturation.



Title: Postobturation Pain Associated with Tricalcium Silicate and Resin-based Sealer Techniques: A Randomized Clinical Trial    
Speaker: Dr Gabriel Tan
Date: Tuesday 12 October 2021

Available evidence on the biocompatibility of Tricalcium silicate (TSC)-based root canal sealers is generally favourable, but its clinical significance on postobturation pain, which is commonly experienced by patients receiving root canal treatment, has not been widely studied.

The aim of this clinical study was to compare the incidence and intensity of postobturation pain with randomly assigned TSC or resin-based sealer over a period of 7 days. The null hypothesis was that there is no difference in the incidence and intensity of postobturation pain between AH Plus and TotalFill BC sealer.



Title: Immunomodulatory Effects of Antibiotics Used In Regenerative Endodontic Procedures
Speaker: Dr Khoo Shih-Tien
Date: Wednesday 2 June 2021


Conventional endodontic re-treatment and apical surgery are predictable procedures for management of endodontically treated teeth with persistent disease. However, there is no information available that compares these treatment modalities based on patients’ oral health-related quality of life (OHRQoL).

In this study, we aimed to compare OHRQoL of patients who received conventional endodontic re-treatment versus those who received apical surgery and to identify correlations between OHRQoL, clinician-assessed healing outcome and other factors. Following which, we invited a purposive sample of patients to participate in focus group discussions such that more nuanced information on their treatment experiences could be elicited.
