Abstract

Background: The incidence of oral cancers is increasing all over the world. Early detection ofthis important publichealth matter makes them more amenable to treatment and allows the greatest chance of cure.The aim of thisstudy was to investigate the awareness and knowledge on oral cancer among final -year dental students in Iraq.Materials and methods: Questionnaires were delivered to 160 final–year dental students in the College of Dentistry inBaghdad. The questionnaire focused on the awareness/knowledge of oral cancer, earlyand common clinical signsand symptoms andassociated risk factors.Results: It was found that 87% of students were aware of oral cancer. The followings were recognized as signs andsymptoms of oral cancer: persistent ulcer and lymphadenopathy (71 %, 70%), followed by presence of white patch(63%). A satisfactory knowledge was observed on; smoking (86%), family history (84%), old age (63%), sun lightexposure (59%), smokeless tobacco (57%), alcohol consumption (55%) and Immunosuppression (54%).Consideringdilatory risk-factors, a satisfactory knowledge was identified on hot and spicy food (57%), but not on the otherfactors. Although satisfactory knowledge of dental risk-factors including premalignant disorders (84%) and previoushistory of oral cancer (70%) was observed, inadequate knowledge about other factors was observed.91% of futuredentists indicated that oral cancer can be cured when detected early.Conclusion: This study highlighted the need for more education in dental schools to enhance dental professionals’awareness and knowledge of oral cancer, aiding in early diagnosis and treatment of patients

Abstract

Background: Oral squamous cell carcinoma (OSCC) remains a lethal and deforming disease, with a significantmortality and a rising incidence in younger and female patients. It is thus imperative to identify potential risk factorsfor OSCC and oral PMDs and to design an accurate data collection tool to try to identify patients at high risk ofOSCC development.14 factors consistently found to be associated with the pathogenesis of OSCC and oral PMDs. Eight of themwereidentified as high risk (including tobacco, alcohol, betel quid, marijuana, genetic factors, age, diet andimmunodeficiency) and 6 low risk (such as oral health, socioeconomic status, HPV, candida infection, alcoholicmouth wash and diabetes) were stratified according to severity of risk, associated carcinogenicity andclinicopathological effects, using evidence obtained from the International Agency for Research on Cancer (IARC).This review provides understanding of the significance of various risk factors in oral carcinogenesis to help to stratifypatients, especially those with potentially malignant disorders, into high and low risk groups

Abstract

Background: Saliva plays an important role in oral health. Several salivary proteins are involved in the antimicrobialdefence mechanism and are able to eliminate or inhibit bacterial growth in the oral cavity. Secretory IgA (SIgA) isone of the principal antibodies present in saliva, could help oral immunity by preventing microbial adherence,neutralizing enzymes and toxins.The aim of this study was to investigate the relationship between salivary Streptococcus Mutans (SM) count and S IgAin stimulated whole saliva in children with primary dentition compared to those with permanent teeth in relation tosome oral hygiene parameters.Material and methods: Stimulated whole saliva was collected from 50 children (25 with primary dentation and 25 withpermanent teeth). Salivary flow rate and pH was measured. Oral hygiene index (OHI) and gingival inflammation wasassessed using classical method. S IgA level was measured using an immunoassay kit and SM count was determinedby culture media.Results: Mean salivary flow rate, pH and S IgA were significantly higher among children with permanent teethcompared to those with primary dentition.Compared to primary dentition, permanent dentition was associated with a significantly reduced mean plaqueindex, increased mean gingival index and reduced mean salivary SM count.Although plaque index showed a statistically significant positive correlation with SM count, gingival index showed aweak negative correlation with bacterial count.S IgA, PH and flow rate showed a statistically significant moderately strong negative correlation with bacterial count.Conclusion: This study showed a clear correlation between count of SM in stimulated whole saliva and both SIgA andplaque index
