Reasons for choosing dentistry as a career among dental students in Saudi Arabia.

OBJECTIVE: This study aimed to identify reasons and influential factors for choosing dentistry as a career among dental students in Saudi Arabia. The preferred field of dental specialty following graduation will also be investigated. MATERIALS AND METHODS: A questionnaire was developed and circulated among undergraduate dental students studying at a private dental college in Saudi Arabia. A list of 16 reasons that possibly influenced students' decision to study dentistry was presented and participants were invited to indicate on a 5-point Likert scale the extent each reason influenced their choice of dentistry as a career. The listed reasons were categorized into economic, professional, vocational, social and personal reasons. RESULTS: Totally, 788 out of 970 questionnaires were completed (response rate: 81%). Proportion of female students exceeded proportion of male students (59% and 41%, respectively) and most participants were Saudi students (73%). The top three influential factors on students' decision to study dentistry were "Dentistry is a prestigious profession," "I like to treat people and improve their appearance," and "I like working with people and caring for them." Variations were identified between male and female students and also between Saudi and non-Saudi students in the reasons to choose dentistry as a career. The vast majority of participants (94%) expressed a desire to follow a postgraduate study. Orthodontics and oral surgery were the most preferred dental specialties. CONCLUSION: The social and vocational reasons were the main factors that motivated this group of dental students to attend a dental program. Greater training opportunities should be planned to accommodate the speculated increasing demand for postgraduate dental education in Saudi Arabia.

Radiographic Assessment of the Quality of Root Canal Fillings Performed by Senior Dental Students.

OBJECTIVE: To evaluate the radiographic technical quality of root canal fillings performed by senior dental students at Alfarabi colleges for dentistry, Kingdom of Saudi Arabia. METHODS: Radiographic assessment was conducted for 246 teeth (390 root canals) endodontically treated by senior dental students to evaluate the quality of root canal fillings. Three criteria were evaluated to assess the technical quality of root canal fillings: length, density, and taper. The root canal filling was considered acceptable if it had an adequate length with no voids and consistent taper from the orifice to the apex. Statistical analysis was conducted using Kruskal-Wallis, Mann-Whitney, and chi-square tests (P=0.05). RESULTS: Acceptable root canal fillings were detected in 127 (32.6%) patients. The frequency of an acceptable root canal filling was the highest for the upper anterior teeth (40%). There were significant differences in the length and density among the types of teeth (P<0.05). However, there was no significant difference in the taper among the types of teeth (P>0.05). CONCLUSION: The quality of root canal fillings performed by senior undergraduate dental students at AlFarabi colleges for dentistry was acceptable in 32.6% of patients. This outcome enhanced the poor performance of undergraduate dental students in the area of endodontics.
