OBJECTIVE

The objective of the study was to determine the effectiveness of self-directed learning (SDL) strategy in dentistry by comparing it with lecture. Specifically, the objectives were to describe the students' perception of their learning experience after each TL strategy, compare the students' cognitive performance, determine whether certain student characteristics influence these two variables, and identify whether these two variables are correlated.

Total enumeration was done in the selection of student-respondents. Using a two-treatment counterbalanced experimental research design, two kinds of data were collected after completion of each TL strategy – post-test scores that indicate the students' cognitive performance (lowest score is zero; highest score is 20) and Assessment of University Teaching Activities Questionnaire (A.U.T.A.Q.) results, indicating students' perceptions on their learning experience (5-point scale from strongly disagree to strongly agree).

Results showed that there is a statistically significant difference between the total mean of A.U.T.A.Q. after SDL (M=3.94, SD=.480) and lecture (M=3.74, SD=.658); p =.024. Statistically significant difference (p .05). Nationality and sex did not significantly affect the students' perceptions and cognitive performance except in the third year level. Finally, there is no correlation between these two factors.

It can be concluded that SDL is as equally effective as lectures, but it must be used cautiously at lower year levels where lecture is still more beneficial. Lower year levels exhibited higher cognitive performance after lecture while the higher year levels displayed higher cognitive performance after SDL.

The dental operative microscope has been widely employed in the field of dentistry, particularly in endodontics and operative dentistry, resulting in significant advancements in the effectiveness of root canal therapy, endodontic surgery, and dental restoration. However, the improper use of this microscope continues to be common in clinical settings, primarily due to operators' insufficient understanding and proficiency in both the features and established operating procedures of this equipment. In October 2019, Professor Jingping Liang, Vice Chairman of the Society of Cariology and Endodontology, Chinese Stomatological Association, organized a consensus meeting with Chinese experts in endodontics and operative dentistry. The objective of this meeting was to establish a standard operation procedure for the dental operative microscope. Subsequently, a consensus was reached and officially issued. Over the span of about four years, the content of this consensus has been further developed and improved through practical experience.

The ChatGPT, a lite and conversational variant of Generative Pretrained Transformer 4 (GPT-4) developed by OpenAI, is one of the milestone Large Language Models (LLMs) with billions of parameters. LLMs have stirred up much interest among researchers and practitioners in their impressive skills in natural language processing tasks, which profoundly impact various fields. This paper mainly discusses the future applications of LLMs in dentistry. We introduce two primary LLM deployment methods in dentistry, including automated dental diagnosis and cross-modal dental diagnosis, and examine their potential applications. Especially, equipped with a cross-modal encoder, a single LLM can manage multi-source data and conduct advanced natural language reasoning to perform complex clinical operations. We also present cases to demonstrate the potential of a fully automatic Multi-Modal LLM AI system for dentistry clinical application. While LLMs offer significant potential benefits, the challenges, such as data privacy, data quality, and model bias, need further study. Overall, LLMs have the potential to revolutionize dental diagnosis and treatment, which indicates a promising avenue for clinical application and research in dentistry.

ABSTRACT Teledentistry has been proven to have the potential in addressing the gap in accessing oral health care worldwide. Nevertheless, more information is needed to support evidence-based teledentistry practice in Malaysia. The article aims to review teledentistry in view of implementing it to be a common practice in Malaysia. The authors describe teledentistry application worldwide, as well as its uses in the field of service and education. The article summarises the needs of teledentistry in South East Asia, as well as the ethical perspectives and legal practices. In addition, the article also reviews the opportunities arising from practicing teledentistry, including during the unprecedented COVID-19 pandemic. Following review, teledentistry seems to be a promising path as it could offer solutions to shortages in the workforce, high demand for treatment needs and unequal service distribution due to lack of accessibility in rural areas in Malaysia. Furthermore, teledentistry can extend care to underserved patients and provide opportunities to supplement teaching in dental education. The authors provide recommendations to overcome challenges to ensure a sustainable teledentistry. Incorporating teledentistry into practice in Malaysia is achievable but proper guidelines are required.

ABSTRACT This retrospective study aimed to evaluate patterns of comprehensive dental treatment under general anaesthesia (GA) for healthy children in Universiti Teknologi MARA, Malaysia. The treatment records of healthy paediatric patients who received dental treatment under GA from February 2017 to January 2021 were reviewed. The patients were divided into two groups: (1) less than 6 years old and (2) 6 to 16 years old. Patients’ characteristics were summarised using descriptive statistics while an independent t-test was applied to investigate the influence of “age group” on treatment duration, number of procedures and use of various restorative materials. A total of 125 paediatric patients (67 boys and 58 girls) were included. The patients’ mean age at the time they underwent GA was 5.77 ± 1.94 years old and the average duration of dental treatment was 62.58 minutes. There was a significant difference in the duration of treatment between the two age groups (p < 0.05). Tooth extraction was the most dental procedure performed (63.31%). The 6 to 16 years old group had a significantly shorter treatment duration (p < 0.05). However, no significant differences were found in all procedures (extraction, restoration, preventive and pulp therapy) and the utilisation of composite, glass ionomer cement (GIC) and compomer in both groups. The use of stainless steel crown (SSC) restorations was significantly higher in the less than six years old group (p < 0.05). Most of the dental procedures performed under GA on healthy children were extraction procedures. Children less than six years of old had a longer treatment duration under GA. Composite restorations and SSC were more frequently used in primary dentition.

In recent years, dental treatments of the outpatient children under general anesthesia has gradually developed as a relatively mature behavior management model. Due to the limited operating time and the large patient flow of children in outpatient clinics, higher requirements of management are proposed both in anesthesia and dental treatment phases. The Society of Sedation and Analgesia of the Chinese Stomatological Association organized experts to formulate a guideline of dental treatments of children under general anesthesia in outpatient clinic. The guideline would provide operable implementing criteria for the entire process including general anesthesia in the dental clinics, basic clinical conditions, types of oral diagnosis and treatment, evaluation and preparation before diagnosis and treatment, anesthesia implementation and monitoring, management during the recovery period, common complications and key points of treatments. This guideline will play an important role in the rapid development of the safe and comfort dental treatments of children under general anesthesia in China.
