The popularity of computer-supported collaborative learning (CSCL) in educational settings has been growing as it gives students a chance to create knowledge and solve problems collaboratively. Still, little do we know about the complex dynamics of students’ interactions in CSCL. This dissertation focuses on the social and temporal dimensions of co...

This study used a multilayered approach to map the temporal dynamics of online problem-based learning (PBL) and the transition of students’ roles across time over a full year duration. Based on data from 135 dental students across four consecutive courses throughout a full academic year, the students’ discourses were coded based on the community of...

This study aims to explore the early prediction and forecasting of students’ performance using learning analytics methods. We do so by examining a large number of students at four different time points and employing four machine learning algorithms. We seek to fill a gap in the literature regarding the early prediction of students’ performance vers...

This preface discusses the potential of virtual labs (VLs) as a flexible and immersive alternative to traditional physical labs in light of Technology-Enhanced Learning in Laboratories workshop (TELL 2023), which features seven papers showing various methodologies and perspectives on using VLs. The papers cover topics such as VLs in biomedicine, st...

Teamwork skills are important to practice during higher educational studies to prepare students for the future working life. Since online learning has established itself as a relevant part of higher education, we present here an approach to online team-based learning and show the performance of students during the teamwork, proven by learning analy...

Online computer-supported collaborative learning (CSCL) has risen in popularity in knowledge sharing and problem-solving. This research explored students' online activity in online problem-based learning (PBL) using process and sequence mining approaches. Process mining modeled students' time-stamped activities and links between them. Sequence mini...

Remote learning has advanced from the theoretical to the practical sciences with the advent of virtual labs. Although virtual labs allow students to conduct their experiments remotely, it is a challenge to evaluate student progress and collaboration using learning analytics. So far, a study that systematically synthesizes the status of research on...

Objective: Impacted canines are one of the significant challenges in orthodontics that should be appropriately assessed to provide the best treatment to the patients. Materials and methods: In the present study, 57800 patients were examined over six years to investigate the prevalence, diagnostic procedures, and treatment methodologies for impac...

Introduction In forensic literature, estimating an individual's age has garnered a lot of attention. With increasing age, the size of the dental pulp cavity shrinks as a result of secondary dentin deposits. This could be used as a measure of age. Aside from morphological approaches, radiological approaches might be used to analyze this regression s...

Over the past decade, epistemic network analysis (ENA) has emerged as a quantitative ethnography tool for modeling discourse in different types of human behaviors. This article offers a comprehensive systematic review of ENA educational applications in empirical studies ( $\text{n}=76$ ) published between 2010 and 2021. We review the ENA methods t...

Research has shown the value of social collaboration and the benefits it brings to learners. In this study, we investigate the worth of Social Network Analysis (SNA) in translating students' interactions in computer-supported collaborative learning (CSCL) into proxy indicators of achievement. Previous research has tested the correlation between SNA...

Background: Dental professionals are among the high-risk categories for getting infected with coronavirus disease 2019 (COVID-19) due to their work nature. This study aimed to evaluate the knowledge, attitude, and practices (KAPs) of dental professionals related to COVID-19 and their clinical practice in the Kingdom of Saudi Arabia.

The study was aimed to evaluate the knowledge, attitude, and practices (KAPs) related to COVID-19 and their clinical practice in the Kingdom of Saudi Arabia. OBJECTIVE 1-To evaluate the level of knowledge and attitude reg...

Background: Using of sealant on pits and fissures is likely one of the most generally well-known strategies by the new cavity-prevention systems. Aim: The purpose of this research is to measure the retentiveness of sealants of resin-modified ionomer glass cement (GIC) and resin pits and fissures, on the first permanent molars of special patients...

Aims and Objectives Discomfort associated with the use of fixed orthodontic appliances may have a negative influence on the patient's oral health-related quality of life (OHRQoL). In general, OHRQoL assessments have the potential to provide information on the need to improve the overall quality of care. This study aims to assess the impact of fixed...

Abstract Background: Dental fluorosis is considered one of the dental public health problems in many countries especially those with high level of fluoride in drinking water. Objective: The present study was carried out to assess prevalence and severity of dental fluorosis among an urban and rural population of Al-Rass and two rural suburbs primary...

Background: Secondary dentine is deposition along the wall of the dental pulp chamber leading to a reduction in the size of the pulp cavity with age. Objective: Investigate the three dimensional volumetric change of the root canal systems of mandibular canines teeth in and to correlate the findings with the patient’s age and gender. Materials and M...

Background: Age calculation has become increasingly important in forensic sciences. It considered as the ideal and most accurate method to evaluate the pulp/tooth volume ratio. Cone-Beam Computed Tomography (CBCT) can be used to measure the rate of secondary dentine deposition which is depicted by reduction in the pulp area Objective: The aim of th...
