Linkage Analysis of Polymorphism of CARD8 Gene (SNP: rs2043211) in Relation to Dental Caries: A Case-Control Study Hashim Mueen Hussein, Sura Sabah, Athraa Ali Mahmood Current Research in Dental Sciences, 2026 Objective: Teeth decay disease is a huge health problem and some reports have inferred caspase recruitment domain family member 8 (CARD8), inflammasome sensor involvement in the disease. Several single nucleotide polymorphisms (SNPs) have been detected in the CARD8 gene. The reference SNP 2043211 (rs2043211) variant is situated in its exon region, leading to the dental caries. The study aimed to determine the impact of the CARD8 (rs2043211SNPs) on the susceptibility of caries presence in patients.Methods: The case-control study included 38 participants aged 20-30 years divided into two groups; the first group (17) was healthy with non-carious teeth and the other group (21) was with active decayed teeth. The clinical examination was done for caries detection then the peripheral blood was taken from all included participants of both groups. The CARD8 gene SNP rs2043211 was amplified and sequenced.Results: Hardy-Weinberg Equilibrium (HWE) analysis of CARDS8 at SNP rs2043211 showed a non-significant (NS) difference in both studied groups. The Adenine Thymine (AT) genotype among the decayed participants was 13 SNPs while in healthy participants 8 SNPs with a non-significant (NS) difference (P=.3). Nevertheless, the odds Ratio (OR) of the AT genotype was 1.83 (0.49-6.7, P=.3) and for genotype TT, it was 1.3 (0.3-5.6, P=.7). It was observed that SNP rs2043211 was associated with tooth decay. In addition, OR for the A allele is 0.6 (0.024-1.5) and 1.65 (0.6-4.15) for the T allele with P=.2 for both alleles.Conclusion: Many factors can play an important role in the initiation and progression of the caries directly or indirectly. The allelic variations in the CARD8 gene are to have been associated with the development of decayed teeth among patients.Keywords: CARD8 gene polymorphism, dental caries, sequencing, teeth decay
The Impact of Ginger Mouthwash on Pregnant Women with Stress and Gingivitis by Measuring Different Salivary Biomarker Levels Batool Abbas Tareq, Athraa Ali Mahmood, Hashim Mueen Hussein Eurasian Journal of Medicine, 2026 Background: Gingivitis is common among pregnant women due to hormonal changes, and stress can increase the severity. Chlorhexidine (CHX) is the standard treatment for gingivitis, but its side effects limit its use during pregnancy. Ginger has an anti-inflammatory and antioxidant effect. The research aims to evaluate ginger mouthwash’s impact on gingival health, cortisol, and lactoferrin (LF) levels in pregnant women with stress and gingivitis compared to distilled water and CHX.Methods: The completed research was a parallel 3-arm triple-blind randomized clinical investigation. The study included 45 pregnant women with stress and gingivitis. Clinical periodontal indicators (bleeding on probing [BOP], plaque index [PI], and gingival index [GI]) were examined at baseline visit and after 7 days of using mouthwash, diaphragmatic breathing, and progressive muscle relaxation (PMR). Salivary cortisol and LF levels were measured, and a comparison was made before and after treatment. The participants answered a “visual analog scale-based questionnaire” at the second visit.Results: Significantly reduced in BOP, PI, and GI in all interventions, but ginger and CHX had a greater significant effect compared to placebo. All mouthwashes, diaphragmatic breathing, and PMR significantly reduced cortisol and LF concentrations. However, the responses to the questionnaire showed that ginger and CHX had significant differences in Q1 and Q3, while nonsignificant differences in Q2, Q4, Q5, and Q6.Conclusion: Ginger mouthwash achieved CHX-comparable reductions in BOP, GI, and PI and decreased cortisol and LF concentrations after 1 week from baseline without adverse effects, highlighting a safe, natural alternative during pregnancy., Cite this article as: Tareq BA, Mahmood AA, Hussein HM.

The impact of bite force on the stability of dental implants Nawres Bahaa Mohammed, Zina Ali Daily, Mohammed Rhael Ali, Noor Fathi Kazim, Hashim Mueen Hussein, et al. Plos One, 2026 Background Since dental implants (DI) are endo-osseous implants that are inserted into the bone and periodontium, which ultimately support the occlusal load, a patient’s bite force (BF) may overburden the supporting DI, leading to bone loss and DI failure. The purposes of this study were to explore the effect of the BF on DIs in different locations of jaws, of both genders during three visits, to investigate DI stability in different locations of jaws, of both genders during three visits, and to assess the association of BF and DI stability(ISQ) with the influence of variables (time, implant location, and gender). Methods The current cohort study involved 80 individuals of both genders who had lost some teeth and needed DIs for the anterior and posterior regions of the jaws. After the insertion of the DIs, their BF was examined by the Loadstar™ sensor, and the DI stability was monitored at three visits of these individuals. First visit during the day of insertion of the crown on the abutment of the implant (immediately loading), second visit at six months following insertion, and third visit after 18 months following insertion. Results The data on the anterior and posterior bite forces (BFs) for the male and female participants after the insertion of the DIs were analysed at three visits. On average, the males exhibited a significantly higher posterior BF compared to the females at the respective three visits. Similarly, the average posterior ISQ in the males was significantly increased than in the females at the respective three visits. Results of the two-way ANOVA of all groups for the implant BF and ISQ values were significantly influenced by the interaction of time, locations of the implants, and gender. The association between the BF and DI stability was significant in using the difference in the regression coefficient ( b ), which was impacted by time, implant location, and gender. Conclusions This study found the significantly complex interaction of factors (time, location, gender) influencing on change of BF and ISQ, by affecting the process of ossteointegration. The significantly higher BF in the posterior regions of males, and significantly greater stability of DIs, could have a potential role in the best DIs therapy. In addition, the association of the BF and DI stability is significantly established with the most important factors influencing the change in BF and DI stability. It varies in a dynamic manner as the interface between the bone and the implant matures, and the patient’s gender, time, and anatomical location all play a significant role in its context. The DIs that are loaded early is dependent on the BF. The BF may be crucial in determining the best DI stability.
Correlation Between Periodontal Disease and Oral, Oropharyngeal, and Parapharyngeal Cancers Zina Ali Daily, Nawres Bahaa Mohammed, Samer Majeed Mohammed, Hashim Mueen Hussein Clinical Cosmetic and Investigational Dentistry, 2025 Background Periodontitis is an inflammatory disease, and contributes to several inflammatory conditions, such as cancer. The relationship between periodontal disorders and different human malignancies is not well understood. The purpose of this study is to assess the association of periodontitis severity with cancers in the oral cavity, oropharyngeal and parapharyngeal regions. Methods The sample comprised 300 participants divided into four case groups: 75 oral, oropharyngeal, or parapharyngeal cancer patients with periodontitis (CA-with-P); 75 oral, oropharyngeal, or parapharyngeal cancer patients without periodontitis (CA-without-P); 75 periodontitis (P) patients without cancers; and a control (C) group of 75 healthy individuals. All participants were subjected to a periodontal examination that considered parameters such as bleeding on probing (BOP), plaque index (PI), probing pocket depth (PPD), and clinical attachment loss (CAL). The type of tumours was identified via a histological analysis of a biopsy sample. Saliva samples were also collected, and an enzyme-linked immunosorbent assay (ELISA) kit was used to determine interleukin 8 (IL-8) and nuclear factor kappa B (NF-κB) levels. Results The research findings indicated a significant increase in the number of sites with clinical observations of BOP (85.11,73.84), PI (87.23.88.14), PPD (8.03,6.82), and CAL (8.67,7.34) in groups CA-with-P and P. The CA-with-P, CA-without-P, and P groups had higher levels of salivary IL-8 (192.03, 121.89,89.22) and NF-κB (10.242, 8.172, 6.324) than the C group. Moreover, there was a significant correlation between the severity of periodontitis and the malignancies in the oral, oropharynx, and parapharyngeal regions. Conclusion This study assessed the mechanisms underlying the correlation between these two disorders, as elucidated by higher levels of salivary IL-8, NF-κB and an increase in clinical periodontal parameters. Periodontal bacteria, which contributes to the development of periodontal disorders, could have a major impact on the onset of oral cancers.
Knowledge, Attitudes and Practices of Dental and Medical Students about Hepatitis B Noor Natik, Abeer Salah Salman, Athraa Ali Mahmood, Wassan Nori, Hashim Mueen Hussein Dentistry 3000, 2025 Objective: This study aimed to evaluate and compare hepatitis B's knowledge, attitudes, and practices among dental and medical students in Iraqi universities. Material and Methods: A cross-sectional observational study was conducted from 1 July to 1 September 2024 among second, third, fourth, and fifth-stage medical and dental students. For survey distribution, the questionnaire consisting of four domains submitted to an internet platform (Google Forms). Undergraduate students were invited to participate in the research via a survey link published on specific groups of students in the social networking platforms Viber and WhatsApp. Results: 426 students responded to the questionnaire. There were statistically significant differences in frequency were seen (p < 0.001) regarding source of your knowledge about HBV, route of infection transition, receiving vaccination, doses of vaccine, and periodic checking of titer values of the vaccine. Frequency of answers for questions regarding immunization programs and strategies against HB infection were not statistically different. Additionally, dental students had more frequent positive responses for use of gloves, changing gloves, use of face mask, changing face masks, use of disposable gown, and use of disposable instruments for the patients positive or suspected HB virus (95.4%, 94.6%, 93.8%, 73.0%, 74.3%, and 96.3%, respectively) whereas medical students less frequently used those (67.6%, 62.7%, 59.5%, 24.9%, 47.6%, and 85.9%, respectively). Conclusion: The study revealed that although both medical and dental students were knowledgeable about HBV transmission, vaccination uptake, particularly among medical students, was inadequate.
