Qualitative analysis of student perceptions assessing active learning methods in a therapeutics course
Abdulrahman Alsayari, Dalia Almaghasalah, Arwa Khaled, Yahya Alhamhoom, Asif Ansari Mohammad, Mohammed Ghazwani
July-December 2017, 2(2):8-17
Objectives: To evaluate the implementation of active learning methods in a therapeutic course from students’ perspective. Methods: The project consisted of two phases of work: Phase I was a fieldwork, where students were exposed to the different active learning methods. Phase II was a feedback from students by interview through conducting focus groups, to assess their preference for each learning method. Results: The students regarded the newly implemented active learning methods as generally helpful in developing most of the skills required for the practice of pharmacy, but there were a number of suggestions for improvement. Conclusion: Students indicated that incorporation of these active learning methods resulted in better academic outcomes including in their examinations.

Objectives: To determine the prevalence of self-perceived halitosis among a group of young Saudi female patients residing in Abha- Kingdom of Saudi Arabia. Materials and Methods: This is a cross sectional observational study, an electronic questionnaire was formulated using Google Forms Application, which included 30 questions enquiring factors under investigation. 373 young females residing in Abha responded to the questionnaire. Age range of subjects was (18-45 years). Results: 51.3% of study participants reported self-perceived halitosis, 82.2% of those felt it the most after waking up. 71.9% of those who reported self-perceived halitosis discovered the problem by themselves, 19.6% were told by family or friends, 87% of them never visited a dentist to be diagnosed, 80.9% reported trying to solve the issue without referring to a dentist and 19.1% received a dentist prescribed treatment for halitosis. Conclusions: The prevalence of self-perceived halitosis in our study population is higher than other populations in the Kingdom of Saudi Arabia. Dental health care seeking behavior needs to be focused upon, as less than a quarter of the study participants consulted a dentist regarding their halitosis complaint. Further studies are needed to correlate the factors investigated in this study with self-perceived halitosis.

Knowledge regarding use of oral hygiene aids among dental interns in Saudi Arabia
Nabeeh A AlQahtani
July-December 2017, 2(2):1-7
Context: Toothbrushes with dentifrice are the most widely used method of self-performed mechanical plaque control. Plaque removal exclusively by tooth brushing is difficult in critical inter-dental areas. Several inter-dental cleaning aids have been developed and are available like dental floss, toothpick, uni-tufted and proxa brush. Aims: The aim of this study was to assess the knowledge regarding use of oral hygiene aids among dental interns in Saudi Arabia. Setting and Design: The present study is a cross-sectional questionnaire based study. Methodology: A questionnaire with 12 questions focusing on the application of different oral hygiene aids was developed to assess knowledge among dental interns. Six schools were randomly selected for the study and intern dentists were included in the study. Statistical Analysis: The collected responses were analyzed for descriptive statistics. Results: A total of 393 (87.5%) out of 449 dental interns participated in the research. The mean knowledge score was found to be 5.45±1.71. The maximum and minimum score obtained was 10 and 1 respectively. Overall, majority (59.5%) of respondents were found to have average knowledge regarding oral hygiene aids. Knowledge in good and excellent categories together was found in only 27.3%. Conclusions: The knowledge regarding use of oral hygiene aids among dental interns was found to be inadequate. There is a need to emphasize significance of maintenance phase of treatment especially by self-care measures. Further research regarding behavior and attitudes of dental interns on oral hygiene aids needs to be investigated.

Objectives: To examine the debonding of the acrylic teeth to polyamide denture base under bending stresses, in comparison to that of the conventional heat cure acrylic denture base. Materials and Methods: Eighty maxillary central incisors were divided into two equal groups. Each tooth of Polyamide group was prepared with a “T-shaped connected tunnels”in the cingulam using a twist drill. Four wax blocks, having ten teeth each ware made and processed with polyamide base. For the acrylic group, four wax blocks having ten teeth each were prepared and processed with heat cure acrylic denture base. The blocks were mounted on the Instron universal testing machine, and increasing bending loads were applied at 135 degrees on the lingual side of each tooth using a 3 mm diameter rod until the tooth was de-bonded or the base was fractured. The results were statistically analyzed using Mann-Whitney U Test. Results: The mean bond strength of acrylic tooth to polyamide base was24.89Mpa. (load= 176N).There was no incidence of tooth debonding in the acrylic group. However, the heat cure acrylic base fractured at an average bending load of 316N (stress=44.7Mpa). Conclusion: Within the limitations, this study can provide the following conclusions: The polyamide denture base exhibited excellent fracture resistance, but the bond between the base and the tooth is significantly less than the fracture resistance of acrylic base. There is a significant risk of debonding of the tooth from the polyamide denture base. The bond strength of the acrylic tooth to the acrylic denture base is stronger than the toughness of the acrylic base.
