Teeth and bones of calvarium are important structures from a forensic point of view, as they are extremely resilient to destruction or decomposition, even under temperature variations. Radiology is inevitably an important tool in forensic investigations. Maxillofacial radiology provides a considerable amount of information for the identification of remains and evidence in case of legal matters. The advent of cone-beam computed tomography (CBCT) in the arena of maxillofacial 3D imaging has contributed immensely to forensic science such as the age estimation through teeth, analysis of bite marks, determination of race and sex, etc. The advantages of accuracy in imaging the anatomy, digitized technology favoring easier comparison of records and storage of records for a longer period, cost reduction, dose reduction, and easier portability have made it an unavoidable adjunct in forensic investigations. The aim of this paper is to review and highlight the importance of CBCT in successful forensic identification and analysis. This review is written to address the various aspects of CBCT as a recently developed technology that may be very useful in some forensic contexts, based on searches for current studies in the literature using PubMed, Scopus, Web of Science, and Google Scholar databases, to identify studies published since inception to December 2021, with no language restriction. In conclusion, CBCT is an accessible 3D imaging technology with many applications, one of them being in forensic sciences.

E-learning has completely transformed how people teach and learn, particularly in the last three pandemic years. This study evaluated the effectiveness of additional procedure-specific video demonstrations through E-learning in improving the knowledge and practical preclinical skills acquisition of undergraduate dental students in comparison with live demonstration only. A randomized controlled trial was conducted for the second-year dental students in the College of Dentistry, Jouf University, to evaluate the impact of E-learning-assisted videos on preclinical skill competency levels in operative dentistry. After a brief introduction to this study, the second-year male and female students voluntarily participated in the survey through an official college email. Fifty participants were enrolled in the study after obtaining informed consent. The participants were randomly divided into two groups, twenty-five each. The control group (Group A) was taught using traditional methods, and the intervention group (Group B) used E-learning-assisted educational videos and traditional techniques. An objective structured practical examination (OSPE) was used to assess both groups. The faculty members prepared a structured, standardized form to evaluate students. After OSPE, statistical analysis was done to compare the grades of OSPE between Group A and Group B. Logistic regression analysis was done to express the effect of components of the OSPE on gender, cumulative gross point average (CGPA), Group A and Group B. The results showed a significant difference in the experimental groups after the intervention (p < 0.000). The simulator position parameter demonstrated that the participants had a significant competence level after the intervention by procedure-specific videos (p < 0.000) and an exponential value of 6.494. The participants taught by E-learning-assisted procedure-specific videos and traditional teaching strategies demonstrated an enhanced learning and skill competency level than participants who used only traditional teaching strategies.

Pain, being a subjective phenomenon, is perceived in different manner by individuals based on various factors including age and gender. Various scales are available in literature to assess and record the pain perceived by an individual. Comparison of commonly used pain perception scales among Saudi Arabian population is scarce. A cross-sectional observational study was conducted among 180 subjects who were belonging to 2 age groups namely 7 to 16 years (group 1; n = 90) and 51 to 60 years (group II; n = 90). Subjects with dental pain of pulpal origin were included by employing consecutive sampling. The included participants were asked to record the severity of pain using visual analogue scale (VAS) and Wong Baker facial pain rating scale (WBS) in a computer-generated random order. The data obtained was subjected to statistical analysis. t test was used to compare the pain score recorded using VAS and WBS among males and females. The correlation between VAS and WBS was also assessed. P value < 0.05 was considered statistically significant. All subjects who participated responded to both the pain perception scales. No difference was found between males and females in the pain perception recorded using VAS and WBS in both the groups. A strong positive correlation was found between VAS and WBS score which was found to be statistically significant in both the groups. Both VAS and WBS are reliable tool to record pain perception in both age groups. WBS is found to be easier and more convenient one.

Background: The use of salivary biomarkers offers a non-invasive approach to understanding the metabolic and inflammatory status of hypertensive patients. This study aimed to quantify the salivary nitric oxide (NO), total cholesterol, triglycerides, high-density lipoproteins (HDL), and low-density lipoproteins (LDL) levels in hypertensive individuals and healthy controls in a sub-population in Saudi Arabia. Methods: This cross-sectional study comprised 40 hypertensive patients (test group, 40–50 years old) and 40 age-matched healthy controls who visited the dental hospital in the College of Dentistry, King Khalid University, for dental treatment. Nitric oxide, total cholesterol, triglycerides, HDL, and LDL levels in saliva were assessed. An independent sample t-test was used to compare the results between the hypertensive and control groups. Results: The mean triglyceride and cholesterol levels in the test group were significantly higher (p < 0.05) than those in the control group. Alternatively, the NO level in the test group was significantly (p = 0.014) lower than that in the controls. The triglyceride level was significantly correlated with age in the test group (p = 0.04). Conclusions: This study demonstrated significant differences in the nitrate levels and lipid profiles between hypertensive patients and healthy individuals in a sub-population in Saudi Arabia. The findings indicate that saliva can be used as a non-invasive diagnostic tool for assessing nitrate levels and the lipid profile. However, additional studies with larger sample sizes and more precise testing parameters are required to validate the findings.

This study aimed to quantify the salivary nitric oxide (NO), total cholesterol, triglycerides, high-density lipoproteins (HDL), and low-density lipoproteins (LDL) levels in hypertensive individuals and healthy controls in a sub-population in Saudi Arabia. Methods: This cross-sectional study comprised diagnosed hypertensive patients (test group, 40–50 years old) and age-matched healthy controls who visited the dental hospital in the College of Dentistry, King Khalid University, for dental treatment. Nitric oxide, total cholesterol, triglycerides, HDL, and LDL levels in saliva were assessed. An independent sample t-test was used to compare the results between the hypertensive and control groups. Results: The study included 40 hypertensive patients (20 males and 20 females, aged 40-50) and 40 age-matched healthy individuals (20 males and 20 females). Significant differences in the triglyceride (p = 0.007), cholesterol (p = 0.033), and NO (p = 0.014) levels were observed between the two groups. The triglyceride level was significantly correlated with age in the test group (p = 0.04).

Background: Oral aphthous ulcers (OAUs) are common oral lesions that present with pain and discomfort, compromising oral function including speech, mastication and swallowing. Various modalities of treatment have been reported for management of pain associated with aphthous ulcer. Objectives: The present study assessed the effectiveness of fresh and raw holy basil leaves for management of pain associated with OAU. Materials and Methods: A unicentric outcome assessor blinded study with concurrent parallel design was conducted. Thirty female patients aged 18 years and above who presented with a single, untreated aphthous ulcer were recruited by consecutive sampling from College of Dentistry, King Khalid University. Subjects assigned to the Test group were instructed to chew fresh holy basil leaves and place them in the oral mucosa in contact with the OAU, while the Control group received sugarless chewing gum. Pain associated with OAU was recorded as a pain score using a visual analogue scale, while pain status was recorded as a dichotomous variable and functional pain severity was recorded on a four-point Likert scale. All measurements were made at baseline as well as during the follow-up visits on Day 1, Day 2 and Day 3 following intervention. Non-parametric tests of significance were used for comparison. Results: The Test group performed better than the control group in terms of reduction in functional pain severity, pain status and pain score. Intergroup comparison showed statistically significant difference in pain score and functional pain severity between the Test group and the Control group on Day 3. However, the Test group experienced reduction in pain score by the end of Day 1. Conclusions: Holy basil leaves demonstrated a preliminary reduction in acute self-reported ulcer pain over a 3-day period compared to an active chewing gum control in the female cohort. These exploratory findings indicate potential short-term symptomatic relief, but definitive clinical efficacy warrants validation in larger, randomized trials.
