People with disabilities (PWDs) often have poor oral health and inadequate health services. This disproportionate burden underscores the need for research into barriers to effective and accessible care. This thesis aimed to examine the perspectives of PWDs by investigating their challenges in accessing dental care, Oral Health-Related Quality of Life (OHRQoL), and levels of dental fear and anxiety (DFA). In addition, the thesis investigated the role of education in preparing providers for special care dentistry (SCD). Five original studies investigated clinical, institutional and educational factors that influence oral care utilising various study designs. The challenges of dental care and education for PWDs were investigated in Trinidad and Tobago (T&T) by interviewing healthcare professionals (HCPs) and caregivers. Surveys assessed OHRQoL and DFA of patients aged 6–18 years at the Special Needs Dental Clinic (SNDC) and the Child Dental Health Unit (CDHU). The impact of a workshop on SCD for dentists, dental students and allied HCPs was evaluated using questionnaires. An international survey assessed the effect of dental student training delivered at European and American universities. Barriers to care included cost, limited access to dental care for PWDs, and HCPs’ readiness. OHRQoL among children at these clinics was generally poor, especially for those with disabilities, who were significantly more likely to experience DFA at a moderate level than those without. Lack of knowledge and professional development motivated participants’ attendance at the SCD workshop. The participants perceived communication and non-compliance as the main challenges in dental treatment at the SCD workshop. The dental students showed a positive intention to treat PWDs after SCD training. Variations in clinical exposure, health care systems, and cultural expectations were observed between the international universities. This thesis indicates that addressing barriers in oral care access, clinical preparedness, and training can improve dental experiences for PWDs. Educational initiatives may foster positive attitudes and readiness among HCPs, leading to better dental care, improved OHRQoL, and reduced DFA among PWDs.
