Keynote: Dental patients’ education on oral cancer and its risk factors in Saudi: Situation analysis including multiple perspective of dentists and dental-patients
Time : 10:00 Am - 10:45 Am
Mohammed Jafer has completed his MPH and Dental Public Health Residency from Case Western Reserve University, Ohio and is pursuing his PhD at Maastricht University Faculty of Health, Medicine and Life Sciences, Netherlands. He is the former Vice-Dean of Jazan University Dental School, Saudi Arabia. He has published several papers in reputed journals and was a key-note speaker at the 1st International Oral Cancer conference in Saudi Arabia on February 14, 2017. He has recently been awarded the Saudi Aramco Prize for Public Health, 2017 for his work related to oral cancer prevention.
Oral cancer is a major oral health issue in the Jazan region of Saudi Arabia. According to the Saudi Cancer Registry, Jazan region has the highest prevalence of oral cancer in the country. However, limited effort regarding investigation and prevention of oral cancer and its risk factors has been initiated. Moreover, there is a lack of insight into dental patients’ education of oral cancer and its risk factors by dentists and dental-students that could contribute to reducing such disease burden in Jazan. Therefore, a multi-angle approach with five formative studies to investigate the practice of dental patients’ education in Jazan University Dental School clinics including dental students, dentists and dental patients was conducted. Data was collected through observing 95 dentists practices, questionnaire measuring dentists’ knowledge of oral cancer (n= 228), dentists’ perspectives (6 focus group interviews), patients perspectives (40 one-on-one interviews) and patients questionnaires (n= 300) to assess their knowledge and perception of oral cancer and its related issues including dental patients’ education practice. These studies revealed that the practice of dental patients’ education regarding oral cancer and its risk factors is limited. The lack of dental patients’ education practice and skills in the Jazan University Dental School formal education and training and the lack of dental patients’ education enforcement from the clinics supervision may have contributed to this current situation.

Cheek-biting commonly reported by patients with Temporomandibular Disorders (TMDs). This check biting may cause cheek-bite keratosis. The aim of this research is to study the prevalence of cheek-bite keratosis among TMDs patients. Cross-sectional survey conducted on 373 TMDs patients seen in the TMJ clinic by one TMJ specialist since 2013. Convenient sampling technique was followed where all screened patients having TMDs included in the study. TMDs patients who have check-bite keratosis are 226 patients (60.6%). Female TMDs patients are the majority (75.60%) and 78.8% of TMDs patients with cheek bit keratosis were female. The highest number of TMDs patients (4.6%) was at age of 20 years old. Cheek-bite keratosis is an important sign for TMDs screening for the general dentist in the first dental visit. Dentist who find cheek-bite keratosis during intra-oral examination, advised to ask more screening questions and do more clinical examination for TMDs.

Many carcinogenic agents are emphasized as predisposing factors for dysplastic changes leading to OSCC, but inflammation caused by odontogenic trauma has been ignored to certain extent. NF-κB family has vital role in the inflammation and is considered to be involved in the initiation and progression of oral cancer. The purpose of this study was to see the cause and effect relationship between the traumatic inflammation and the dysplastic changes observed in confirmed cases of OSCC using NF-κB pathway. The study was conducted on a sample of 28 patients of OSCC collected from University affiliated hospitals. Among these 23% patients presented with the clinical evidence of odontogenic trauma females made up 48% of cases, while 52% were males. The majority of lesions occurred on the buccal mucosa (57.14%) followed by tongue (33.33%) and retromolar region (9.53%). These specimens were then processed for the NF-κB analysis. The real time PCR reactions were set up for each sample after reverse transcriptase (RT-PCR) reactions with Eva Green primers. All the patients presented with mucosal trauma due to odontogenic reason showed threefold increase of NF-κB amplification, as compared to the other OSCC samples suggesting that inflammation caused as a result of trauma was one of the important initiating factors for dysplastic changes. Early detection and elimination of local trauma due to odontogenic causes could have prevented the dysplastic changes.

He is a member of the Tanzanian Dental Association (TDA) and International Association for Dental Research (IADR).
Background & Aim: There are no reports on the associations between oral problems and lifestyle from adolescents in Maasai population areas. This study aimed to estimate the prevalence of oral diseases/problems and identify associated lifestyle factors in adolescents living in Maasai population areas, Tanzania.
Methods: The sample comprised a random selection of 23 out of 66 rural public primary schools. Classes with children aged 12-14 years were identified from each school and all adolescents in selected class were invited to participate. A questionnaire investigating lifestyle factors (dietary/behavioral) and a clinical examination was done.
Results: Out of a total of 989 invited adolescents, 906 (91.6%) accepted to participate (age 12-17 years, mean 13.4 years, SD 1.2). The prevalence of oral diseases is presented in brackets: bleeding gums (40.9%), dental fluorosis (89.7%) and TMD pain (11.8%). Logistic regression analyses revealed: adolescents with low frequency of cleaning teeth (OR=10.0, CI: 5.0-16.7), those who used wooden toothbrush (OR=1.7, CI: 1.1-2.5) and those with poor oral hygiene (OR=50.0, CI: 14.3-100.0) were more likely to present with bleeding gums. Adolescents reported to use non-tap water (OR=14.0, CI: 3.3-59.3) and trona (OR=11.6, CI: 5.8-23.0) were more likely to present with dental fluorosis. Adolescents with eating problems (OR=3.1, CI: 1.7-5.8) and those reported to clench and/or grind their teeth (OR=2.8, CI: 1.8-4.5) were more likely to present with TMD pain.
Conclusions: Oral problems were common among adolescents from Maasai population areas and associated with lifestyle factors such as oral hygiene, dietary habits and tooth clenching.

Background: Clinical problems of the temporomandibular joint (TMJ) and the masticatory musculature are both included in the term temporomandibular disorder (TMD). The field of TMD is well known for being one of the more controversial topics in dentistry. Studies show a marked difference in the prevalence of TMD from 16 to 64 %. The purpose of the present study was to examine whether patients with clinical TMD had pathological findings utilizing magnetic resonance imaging (MRI).
Material & Methods: The study population consisted of 64 patients with clinical TMD. Symptoms were recorded using a questionnaire, clinical examination included diagnosing occlusion in centric relation, and then a standardized MRI was performed. The images were read, utilizing the Piper system by the treating dentist and then read by two experienced radiologists blinded to clinical data.
Results: All patients had molar interferences in centric occlusion and limited anterior guidance. The patients also had changes in disc position when examining the MRI scans. 68 of the joints (55%) had changes corresponding to Piper IVa classification. It was also found more severe changes like disc degeneration, changes in condylar head, abnormal reduction and restriction in anterior movement. The most severe changes were corresponding to Piper Va and Vb (34 joints, 27%).
Conclusion: All the patients assessed due to TMD showed changes in their TMJ on MRI.
We also found posterior interferences in their occlusion and loss of anterior guidance.

In 2012, he served as Supervisor at Bioengineering University of Genoa. He is actively involved in research since 2006, focusing on dental implants, dental materials and prosthodontics. He participates in national and international dental conferences about vital pulp therapy.
Vital Pulp Therapy (VPT) is a biologic and conservative treatment modality to preserve the vitality and function of the coronal or remaining radicular pulp tissue in vital permanent teeth. The most important biological target of these therapeutic solutions is the dentinal bridge formation. Clinically, dentinal bridge formation is valued by Rx analysis where the pulp chamber is reduced after 3-6 months from VPT therapy. Usually, Clinical practice success on VPT procedure is made when no spontaneous pain is present. Clinical parameters to achieve success in VPT are no encoded. Aim of this lecture is to show the clinical methodic to achieve clinical success in VPT cases on permanent teeth.
