The Effect Of Smoking On Clinical Presentation And Expression Of Tlr-2 And Cd34 In Oral Lichen Planus Patients: Clinical And Immunohistochemical Study, Enji Ahmed Mahmoud, Nermin Yousif, Nermin Raouf

Dentistry

Background: Oral lichen planus is a chronic inflammatory disease which is considered as a potential precancerous condition. Numerous studies have confirmed that inflammation is a strong risk factor for cancer development. Smoking is associated with potentially malignant disorders of the oral and oropharyngeal mucosa. The adverse consequences of smoking in various pathologies are mediated by its effects on the immune-inflammatory system. Little is known about the influence of cigarette smoke content on the course of OLP and inflammatory response. Methods: Twenty oral lichen planus smoker patients, 20 oral lichen planus non-smoker patients and 20 control patients were included in this …

Single Nucleotide Polymorphism Of Prostaglandin-Endoperoxide Synthase (Ptgs2) And Defensin Beta 1 (Defb1) Genes In Malay Chronic Periodontitis Subjects, Jagender Singh Jasmin Kaur

Student Works (2020-2029)

The association of prostaglandin-endoperoxide synthase 2 (PTGS2) and defensin beta 1 (DEFB1) single nucleotide polymorphisms (SNP) with chronic periodontitis (CP) have been widely studied amongst different ethnic groups such as the Chinese and European population. Thus far, no study has been done on the Malay ethnic group. Hence, this study assessed the allele and genotype frequencies of PTGS2 and DEFB1 variants in subjects with CP and periodontally healthy individuals in Malaysian Malays. Samples of 78 Malay CP subjects and 62 periodontally healthy controls were obtained from Malaysian Periodontal Database and Biobanking system (MPDBS) for this study. DNA samples were genotyped …

Preschool Children's Toothbrushing Behaviour And Association With Their Oral Health, Muhammad Khan Iqra

Student Works (2020-2029)

Toothbrushing is an important yet neglected behaviour that has affected oral health of preschool children (4-6 years). Factors like dietary habit, socioeconomic status and oral conditions also affect oral health of preschool children. Despite intervention efforts, recent investigations reported high prevalence of early childhood caries (ECC) and oral diseases among this age group across different populations. Therefore, it is imperative to understand the relationship between toothbrushing behaviour and oral health status of preschool children to prevent oral diseases, hence improve their oral health. The aim of the current study was to evaluate toothbrushing behaviour of preschool children, assess their oral …

Investigation Of Inflammatory Responses Following The Use Of Novel Anisotropic Hydrogel Tissue Expander In The Skin Of Maxillofacial Region, Salim Igdayir Kholoud Mohamed Ali

Student Works (2020-2029)

Background: The purpose of tissue expander is to grow healthy supplementary tissue under the controlled of mechanical force exerted by the tissue expander. In the field of reconstructive and plastic surgery, the use of soft tissue expanders are important for growing healthy supplementary tissue. However, the molecular mechanism associated with the inflammatory response associated with the force generated from the use of tissue expanders is still not characterized. Among the many types of tissue expanders, anisotropic type of hydrogel tissue expander was chosen due to its ability to produce controlled incremental inflation on the tissue that enhance cellular adaptation and …

Mageb2 Antibody As Potential Diagnostic And Predictive Tool In The Progression Of Oral Cancer, Awang Hasyim Noratikah

Student Works (2020-2029)

Introduction: Oral squamous cell carcinoma (OSCC) represents more than 90% of all oral cancer. Despite advances in diagnostic and therapeutic modalities, mortality and morbidity rates have not improved in the last decade. Hence, alternative diagnostic and therapeutic approaches are urgently needed. Cancer testes antigens (CTA) are proteins that are expressed in various malignant tumours but its expression in normal tissue is restricted to testes and occasionally placental trophoblast. Due to its exclusive presence in different types of malignant tumors, and their ability to trigger immune responses, CTA are considered promising biomarkers for cancer vaccines. A previous protein array study reported …
