This observational cross-sectional study investigates the relationship between bruxism, anxiety, and periodontal health among fourth- and fifth-year dental students at Al-Hawash Private University. Bruxism, a habit that involves grinding or clenching teeth, may be influenced by stress and anxiety and could relate to changes in gum health. The study focuses on dental students due to their academic stress and workload, aiming to understand how these factors may be connected. Participants will be assessed for probable bruxism, anxiety levels, and periodontal status using clinical evaluations and questionnaires. These measurements will happen once at enrollment to explore possible associations between the psychological and dental health variables. No interventions or treatments are administered, as the study observes existing conditions and habits. Throughout the study, participants will provide information through questionnaires and undergo periodontal examinations to evaluate anxiety, bruxism signs, and gum health at the start. Researchers will analyze these data to identify links among these factors. Participation involves a single assessment session, and safety monitoring or long-term follow-up is not part of this study. The study will run until September 2026.

Researchers are investigating the role of Candida albicans, a common fungal pathogen, in patients with periodontitis, an oral disease characterized by inflammation and destruction of the structures supporting the teeth. This study focuses on Syrian patients to better understand how Candida albicans may affect periodontal health in this population. The study is observational and aims to identify the presence and impact of this fungus in people with chronic periodontitis. Participants will undergo a clinical periodontal assessment, including examination of attachment loss and probing depth. Samples of plaque from beneath the gums subgingival pockets will be collected for microbiological testing to detect Candida albicans. The study groups include Syrian patients diagnosed with periodontitis and Syrian individuals without periodontal disease. During the study, participants will be assessed at enrollment with periodontal screening and recording index measurements. Researchers will analyze subgingival samples to detect Candida species. The study involves no treatment and aims to monitor oral health status and fungal presence. Participation requires consent and includes patients aged 18 years and older. The study is expected to continue until September 2026.

Researchers are evaluating the immediate plaque removal effectiveness of the natural Miswak compared to a traditional manual toothbrush using the Modified Bass technique in patients with fixed orthodontic appliances. The study aims to determine if there is a significant difference in plaque reduction between the side cleaned with Miswak and the side cleaned with a manual toothbrush. This randomized split-mouth clinical trial addresses the challenge of maintaining oral hygiene during orthodontic treatment, where brackets and wires can trap dental biofilm. Participants will have half of their mouth cleaned with the natural Miswak, prepared by removing outer bark and soaking before use, applying vertical and horizontal strokes for 3 to 5 minutes. The other half will be cleaned with a conventional manual toothbrush using the Modified Bass technique, also for 3 to 5 minutes. This single clinical session uses a split-mouth design to minimize variability by having each participant serve as their own control. During the study visit, dental plaque will be assessed using the Modified Quigley-Hein Plaque Index immediately before and after brushing. The study involves no follow-up beyond this session. Participants will be monitored for proper brushing technique and plaque reduction to compare the immediate efficacy of both oral hygiene tools in orthodontic patients. The total participation is limited to this single visit.

This research aims to compare how traditional cigarettes, e-cigarettes, and narghile hookah smoking affect periodontal health among students at Al-Hawash Private University. Despite growing awareness of smoking dangers, especially among young people attracted by safer alternatives, no previous study has directly compared the impact of these three smoking types on gum and teeth health in one group. The study observes groups of cigarette smokers, e-cigarette smokers, and narghile smokers, each with specific daily use habits for at least one year. It is a non-interventional observational study where participants are evaluated without receiving any treatment, focusing on their current smoking habits and periodontal condition. Participants will undergo assessments measuring plaque levels, gum inflammation, pocket depths in gums, attachment loss, bleeding on probing, tooth mobility, gum recession, and furcation involvement at enrollment. These measurements help researchers understand different effects of each smoking type on periodontal tissues. The study runs from June 2025 until August 2026.
