Background: Dental anxiety is one of the most common phobias and among the major problems in dentistry. Students in medical field are future health professionals who are supposed to provide a positive attitude toward dentistry to the society. However, if they have dental anxiety, their attitude toward dentistry is likely to be negative. Aim: The aim of this study was to determine the prevalence of dental anxiety among undergraduate students at Muhimbili University of Health and Allied Sciences (MUHAS). Methodology: This was a descriptive cross-sectional study involving undergraduate students at MUHAS. Data were collected using self-administered Modified Dental Anxiety Scale questionnaire with additional questions on demographic characteristics and a list of fear-provoking factors. Data were entered and analyzed using the Statistical Package for the Social Sciences computer software version 19.0 (2010; IBM Corp., Armonk, NY, USA). Chi-square test was used to assess the association between variables, and the significance level was set at P < 0.05. Results: This study enrolled 252 undergraduate students with an age range of 18–39 years. More than half (54.4%) were males. Most (55.2%) of the participants had some degree of dental anxiety. The prevalence of dental anxiety was relatively higher in females (70.4%). The association between dental anxiety and the degree courses was significant. Dental students had the lowest dental anxiety level compared to nondental students. Conclusion: The prevalence of dental anxiety among undergraduate students at MUHAS was high. Dental anxiety was significantly higher in female students. There was a significant relationship between dental anxiety and the degree course of the participants.

Aim: The aim of our research is to establish the prevalence of Elongated Styloid Process in Saudi Arabia Jeddah using panoramic radiographs and the assessment of the patient's age, gender, sides, and type. Materials and Methods: This study was performed as a retrospective analysis on digital panoramic radiographs using the record base archives of the International Medical Center, dental department in Jeddah. In this study, 1971 radiographs were examined. The radiographs reviewed were taken between January 2010 - January 2017 using KaVo radiographic machine model OP300-1. The patient demographics, length of the SP at the right and left side and the classification pattern were entered in spreadsheet in microsoft excel 2007; and the statistical calculation were obtained by using SPSS ( Statistical Package for Social Science ) version 21 software. 0.01. Result: The mean length of the styloid process was 29.05 mm in our study . In females it was 29.17 mm and in males it was 31.30 mm with the length being more in males than in females and the result being statistically significant with p value (0.000). The length of the styloid process increased with the age progressively and it was statistically significant with p value 0.004. The average length of right side styloid process in all age groups is 30.2mm and the left side is 29.6mm with the right side being more than the left and the results were statistically significant p value (0.00). SP Type I elongation was the highest on both the right and left sides and also in all the age groups as compared to Types II and III.

Aim: This study aimed to assess the prevalence of impacted teeth and their associated pathologies according to age, gender, site, and type of impaction in the Saudi population in the city of Jeddah using digital panoramic radiographs. Materials and Methods: A total of 2431 digital panoramic radiographs taken during the period between January 2010 and January 2017 were analyzed following exclusion criteria. Finally, a total of 2229 X-rays were considered for the study. Results: The most commonly impacted teeth were upper and lower left third mandibular molars. The most common angulation type was horizontal and the least was vertical impaction. Based on the overlying tissue covering the impacted teeth, soft-tissue impactions were the most common. There was no statistically significant outcome regarding the pathologies as cysts or tumors associated with the impacted teeth. There was a significant association between mesioangular impacted teeth and caries in the second molars. Conclusion: In our study, partial bony mesioangular impactions in level B positions were associated with significant distal caries in the second molars, whereas vertical impactions in level C positions caused increased distal bony loss and resorption which would warrant early surgical intervention in patients and also help in informing the patients on the ramifications of delaying the same. A statistically significant number of partial bony impacted third molars were carious, warranting early intervention.
