Oral lichen planus is the main disorder associated with DG. However, DG may be a feature of bullous disease and connective tissue disease.

BackgroundA previous study has shown that dental practitioners in Benghazi believed that the less prevention-oriented education system is one of the barriers to applying preventive dentistry.ObjectiveTo assess attitudes and perceived competence of the dental graduates in Benghazi towards prevention and early management of dental caries.MethodsA cross-sectional, questionnaire-based survey was conducted among internship students attending the Department of Community and Preventive Dentistry in Faculty of Dentistry, Benghazi, Libya. The participants were asked to provide demographic information, to respond to statements about their attitudes towards preventive dentistry, and to answer questions regarding their perceived competence in applying preventive dentistry procedures.ResultsData from 108 Libyan dental graduates were analysed for this study, of which 64% of them were females and 42.1% of them passed their final year with grade: acceptable. The most acknowledged aspects of preventive dentistry were being useful and essential to the community (95.4 and 90.8%, respectively). The percentage of participants expressing a proficiency in providing oral hygiene instructions was the highest (95.4%). There were differences between study subgroups in their perceived competence of preventive dental practices by gender and academic performance (p≤0.05).ConclusionThis study highlighted that the currently implemented undergraduate education programme in Benghazi dental school does not provide dentists with the required attitude and skills to fulfil their role in providing preventive-oriented health services.

One third of dentists from three Arab dental schools indicated they would refuse to treat HIV + patients. Adequate knowledge and moral beliefs reflecting professional ethics were associated with lower odds of refusal counterbalancing the association with attitude indicating increased concern for risk of infection with implications for dentist education and training.

Objectives: To investigate the prevalence of the most common occupation-related health problems as well as factors associated with their incidence among dental practitioners. Materials and methods:A cross-sectional, questionnairebased survey of Libyan dental practitioners. Participants provided information regarding their experience of occupationally related problems they encountered over the past 12 months which included inquiries about musculoskeletal pain, percutaneous injuries, allergy, eye and sight problems, and hearing problems.Results: Musculoskeletal problems were the most frequently reported (48.2%), followed by percutaneous injuries (35%), eye problems (22%), allergy (11%) and hearing problems (7.6%). Musculoskeletal problems were significantly higher among dentists who work in private sector, full timer as well as those who prefer to work in a sitting position (p = 0.021, 0.027 and 0.008, respectively). Practitioners with less than 5 years in service reported significantly higher percentage of percutaneous injuries (p = 0.027) than their senior counterparts, whereas practitioners who spent more than 10 years in service were more likely to suffer from visual disturbances (p = 0.033). Conclusion:The findings of this study indicate that musculoskeletal problems and percutaneous injuries are the most commonly reported occupational health problems among dentists, whereas allergic reactions and hearing problems are the least reported ones.Clinical significance: Dentists should use alternate working positions to minimise musculoskeletal problems and adopt more effective strategies to prevent percutaneous injuries particularly among novices.
