Aims: To investigate self-perceived stress level of senior dental students in Saudi Arabia during different fixed prosthodontics procedures. Also, to explore the possible stress-related factors during each procedure. Settings and Design: A structured, close-ended, and open-ended, anonymous questionnaire was distributed in a website format to senior dental students of 19 dental schools in Saudi Arabia. Materials and Methods: Students were asked to rate the level of stress they feel during different fixed prosthodontics procedures on a scale from 0 to 10. They were also asked to rate the adequacy of their preclinical training in these procedures and how many times they have performed each of the procedures clinically. Statistical Analysis Used: Descriptive statistics were presented in means, percentages, and standard deviation and inferential statistics were performed using One-way ANOVA, independent t -test and Pearson’s correlation. Results: About 423 students answered the questionnaire, in which 228 (54%) were females and 195 (46%) were males. Vital tooth preparation (5.27 ± 2.459) and pos space preparation (5.13 ± 2.766) were rated as the most stressful procedures ( P < 0.05). Fear of error or mishaps was the most reported reason for stress during these two procedures. Pearson’s correlation showed significant but weak negative correlation between stress scores and number of times the student has performed the procedure ( P < 0.05). Students who believe that they had adequate preclinical training reported significantly lower stress scores ( P < 0.05). Conclusion: Self-perceived stress among dental students is related to the type of procedure they perform in the clinic and how frequent they have been exposed to it during their preclinical training.
Aim: This study aims to investigate the morphometrics of permanent canines in establishing sexual dimorphism in the native Arabian population. Methods: Thirty (male = 12; female = 18) native Arabian subjects, with ages ranging between 20–45 years. The mesiodistal (MD), cericoincisal (CI) and labiolingual (LL) widths of the teeth 13, 23, 33, and 43 and the inter-canine distance in maxillary (MaxICW) and mandibular (ManICW) arches were measured using a digital caliper. The gran method was used for establishing sex dimorphism among the study subjects. Descriptive statistics were employed using SPSS version 20.0 (Armonk, NY, USA, IBM Corp.). Results: The comparison of either of the measurements (MD, CI, LL, MaxICW and ManICW) were shown to be statistically significant (p > 0.05). The overall mean values of teeth 13, 23, 33, and 43 for CI, LL, MaxICW, and ManICW were lower for females than males (p > 0.05). The MD width was higher in females than that of males (p > 0.05). The sex dimorphism value for teeth 13, 23, 33, and 43 were 0.98, 0.99, 1, and 0.99, respectively. The standard canine index was high for mandibular teeth and lower for mandibular teeth, and SCI values for teeth 13, 23, 33, and 43 were 0.219, 0.218, 0.257 and 0.256, respectively. Conclusion: The morphometrics of permanent canines are helpful in sex determination with the aid of odontometric analysis.
