This study aims to explore experiences of Malaysian undergraduate dental students on the appropriate use of systemic antibiotics for pulp and periapical pathology. Final-year students from thirteen Malaysian dental schools were invited to participate in an online survey on the use of systemic antibiotics for treatment of pulp and periapical infections. The questionnaire was divided into i) respondents’ demographic data; ii) experiences and practices related to antibiotic use in managing endodontic pathology. Two open-ended questions were included to assess awareness on i) existing guidelines for prescribing antibiotics for endodontic pathology; ii) consequences of overprescribing antibiotics. Response rate was 100%. Amoxicillin (with or without clavulanic acid) (85.0%) was the most used antibiotic while clindamycin (53.7%) was chosen for penicillin-allergic patients. Antibiotic treatment was carried out for five-day duration. Cases of acute apical abscess with systemic involvement received the most antibiotic prescriptions (88.5%). A considerable number of students inappropriately prescribe antibiotics for asymptomatic apical periodontitis with or without sinus tract (29.0%) and reversible pulpitis (5.6%). 87.0% of respondents were aware of detrimental effects of antibiotics overuse. Despite high awareness on antibiotics’ side effects, some students still prescribe antibiotics unnecessarily. Enhancement of undergraduate endodontic education is highly recommended to avoid unnecessary antibiotic prescriptions.

EXPLORING THE USES, STERILIZATION AND STORAGE PROTOCOLS OF EXTRACTED HUMAN TEETH FOR RESEARCH ADVANCEMENTS: A SCOPING REVIEW Extracted human teeth (EHT) have long served as invaluable specimens in dental research, offering valuable insights into dental science and biomaterials. This scoping review aims to document the current uses of EHT in dental research and to identify the sterilisation and storage protocols. The study employed scoping review methods. Relevant databases (PubMed, Scopus, and Science Direct) were searched using the terms “extracted human teeth” and “in-vitro” to identify articles for inclusion. The most recent articles published over five years (2019-2023) and those in English were included. Two reviewers independently conducted the selection process, and the decision was consensually made. A descriptive statistical assessment was performed to analyse the studies involving EHT and the sterilising and storage solutions used. A total of 105 articles were reviewed: Endodontology (32%), Dental Materials (24%), Conservative Dentistry (20%), Prosthodontics (8%), Regenerative Therapy (6%), Oral Biology (5%), Orthodontics (4%), and Periodontology (3%). 71% of the reviewed papers did not report the sterilising and storage methods for EHT. When reported, sodium hypochlorite was most commonly used (15%). However, the concentrations and immersion time in the sterilising solutions were inconsistent. The most frequently used storage solutions to keep EHT from dehydration are saline (11%) and distilled water (10%). In conclusion, extracted human teeth continue to be extensively utilised in dental research. Nonetheless, the reporting and standardisation of sterilisation and storage methods are notably inadequate. A standardised guideline for sterilising and preserving extracted human teeth for various types of research is essential to mitigate variability and promote result uniformity. There is a stark absence of consensus regarding the optimal procedures for storing and sterilising EHT, even when used for the same laboratory investigations and different types of dental research.
