Abstract
AIM To investigate dental students' self-reported confidence in learning about various domains of patient safety during their clinical training years. METHODS The Health Professional Education in Patient Safety Survey (H-PEPSS) was distributed to the fourth- and fifth-year undergraduate students, interns and postgraduate dental students. The survey explores how the seven domains of the Canadian Patient Safety Institute Safety Competencies Framework and wider cases of patient safety issues are presented in dental education, as well as participants' self-reported comfortability regarding revealing about patient safety issues. A comparison of the patient safety domains scores were assessed through learning scenarios (classroom and clinical), gender, level of study and type of institution. RESULTS Out of 409 participants, 359 undergraduate dental students and 131 postgraduate dental students responded to the survey. Irrespective of the groups, all dental students were most confident regarding their learning aspects about skills pertaining to clinical safety and effective communication and least confident in learning related to managing safety risks. All the patient safety factors irrespective of the scenario, scored above 75% and thus interpreted as good competence. Statistically significant differences were reported among the genders in the classroom scenario for learning about communicating effectively with the patients regarding patient safety issues (p < 0.05). Male dental students, undergraduates and those in the private institution were significantly less confident about recognizing and reporting to immediate risks in the clinical scenario compared to their respective counterparts (p < 0.05). CONCLUSION Based on the results, the dental students are quite confident with regard to the learning aspects of clinical patient safety, nevertheless, their confidence in learning certain patient safety aspects warrants further improvement. This implies a need to address the impact of regular interventions, extra motivation and repeated mentoring in both the classroom and clinical scenarios on improving dental students' confidence about patient safety.

Abstract
BACKGROUND There are only limited studies that have determined the antibacterial effects of various remineralizing agents that can be beneficial to children. AIM The aim of this study is to compare the efficacy of tricalcium phosphate (TCP), calcium sodium phosphosilicate (CSP), and casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) enhanced with fluoride in reducing the Streptococcus mutans (SM) levels in saliva of children. MATERIALS AND METHODS Out of 245 children, 120 of them with SM colony forming units (CFU)/ml in the range of 104-106/ml of saliva were assigned to four groups: (I) TCP; (II) CSP; (III) CPP-ACP enhanced with fluoride; and (IV) control. Salivary samples were collected at intervals of 1 week, 2 weeks, and 4 weeks and the number of CFU/ml of SM in saliva were counted post 48 hour incubation. RESULTS After 1 week, 2 weeks, and 4 weeks, there was a significant reduction in the mean score of SM (P < 0.05). The maximum reduction in the CFU/ml in the saliva was seen in the 1st week after the commencement of the brushing in all the three test groups. Group III children demonstrated the maximum reduction of 15 × 105 CFU/ml, followed by Group II children with 10 × 105 CFU/ml. CONCLUSIONS Twice daily use of CPP-ACP with fluoride, CSP, and TCP caused a significant reduction in the levels of SM in saliva.

Abstract
Objective This study aimed to examine the effectiveness of oral health intervention on the improvement in knowledge and self-reported oral health behavior among 6–8 year old female primary school children in Riyadh, Saudi Arabia. Materials and methods The sample consisted of 1661 girls in primary schools who are 6 to 8-year-olds (first, second and third graders). The children’s level of knowledge was assessed by a self-administered questionnaire that was formulated for this specific age and divided into two parts; oral health knowledge and self-reported oral health behavior. There were seven multiple choice questions and one true/false question with five underlying parts in the questionnaire which contained basic information about oral health knowledge, oral hygiene practices and certain habits that affect teeth. The questionnaires were distributed before and six weeks after implementation of the oral health educational program to measure the level improvement of knowledge regarding oral health among these children. Results All the questions showed statistically significant improvement in knowledge and self-reported behavior in the post intervention group. There was a significant increase in the level of knowledge by 11.24% and level of self-reported behavior by 25% after intervention (P < 0.001). The highest net change in the knowledge due to intervention was noted among third graders (13.3%), whereas for self-reported oral health behavior, it was noted among first graders (28.3%). Conclusion The results of this study showed that an easy-to-organize and inexpensive school-based intervention can, on a short-term basis, be effective in improving the knowledge and self-reported oral health behavior of children.

Abstract
AIM The aim of this study was to evaluate undergraduate dental students' self-perceptions of their clinical dental environment using a valid, concise and more practical version of the Dental Clinical Learning Environment Inventory (DECLEI) questionnaire. MATERIALS AND METHODS The 24-item DECLEI was self-administered to fourth- and fifth-year undergraduate dental students from public and private dental schools in Riyadh, Saudi Arabia, during the 2014-2015 academic year. Factor analysis revealed three underlying factors associated with the clinical learning environment. Independent sample t-tests were used to evaluate any associations amongst the items, the factors, the total DECLEI score and other demographic variables. For the scoring system, 6-point Likert scale responses were scored on a 100% scale ranging from excellent to poor. RESULTS The mean DECLEI total score was 64.1 (good) of 100. Amongst the factors, the highest mean score, 71.3 (good), was obtained for the patient interactions and professionalism, and the lowest mean score, 50.2 (moderate), was observed for all the negatively worded statements in the DECLEI. The instrument exhibited good discriminant validity as it was able to record significant differences between genders and between public and private institutions in the total DECLEI, the factors and most of the items scored. CONCLUSIONS The new DECLEI scale identified several areas of strength and some aspects that could be improved. Overall, the dental students rated the clinical undergraduate programme as more positive than negative.

Abstract
OBJECTIVE To identify current practices and the preferred caries-related treatment decisions and restorative modalities of primary teeth among pediatric dental practitioners in Saudi Arabia. MATERIALS AND METHODS This was a web-based cross-sectional survey conducted among licensed pediatric dental practitioners in Saudi Arabia. Following the retrieval of the email addresses from the Saudi Dental Council, an email explaining the purpose of the study and a link to SurveyMonkey electronic survey consisting of 23 questions was sent to all the members registered under the pediatric dentistry practitioners, starting in September till December 2013. The data obtained was analyzed using descriptive statistics and chi square with and without tabulation processes. The level of significance was set at p < 0.05. RESULTS A total of 108 [54 (50%) male and 54 (50%) female] pediatric dental practitioners responded to the survey out of 308 targeted individuals for an overall response rate of 35.1%. About 65% of the respondents reported that they have never considered pre-veneered or Zirconia crowns as a restorative option for carious vital anterior primary teeth. About 40% reported doing pulpectomy and restored with composite strip crowns at all times. About 86% of the respondents reported doing pulpotomy and stainless steel crown for restoring carious vital posterior primary teeth whereas 73.8% reported restoring with composite resin. However, 83.1% of the respondents reported that they never used pre-veneered or Zirconia crowns after pulpotomy for restoring carious vital posterior primary teeth. A significantly higher number of male participants reported that they used esthetic pediatric crowns in their practice compared to female participants (p < 0.001). CONCLUSION The prevalence of use of composite resin to restore primary teeth was higher compared to glass ionomer cements and amalgam whereas a limited use of esthetic pediatric crowns was found among the sample surveyed. Esthetic pediatric crowns were more utilized by male compared to female participants.

Abstract
Objective The purpose of this study was to investigate evolving trends in dental post graduate specialty preferences and career aspirations among final year dental students in Saudi Arabia. Materials and methods A cross sectional survey using a self-administered questionnaire was conducted among final year dental students from seventeen universities in Saudi Arabia. The questionnaire enquired about socio-demographic details and the ranking of three of their best preferences among the list of specialties/general dentistry and career options. They were also enquired about their opinion regarding the total time required to become a dentist and their intention to go for further studies abroad. The questionnaire assessed factors influencing their choices using a 5 point Likert scale ranging from extremely important to not important. Binary logistic regression to examine the combined effect of several independent variables on the likelihood of choosing a dental specialization/general dentistry and career option were analyzed. Results The overall response rate was 64.6%. Restorative and Aesthetic Dentistry was the most preferred specialty (n = 98; 17.7%) followed by Endodontics (n = 78; 14.1%); Prosthodontics (n = 65; 11.7%) and Orthodontics (n = 63; 11.4%). The two most preferred careers were ‘Civilian dentist in public sector’ followed by ‘Academic services dentist’. Overall, students reported that the influence of family members in the dental profession, preference for private practice and specific interest in patient population as the most important factors in choosing a specialty/general dentistry. Intellectual content of the specialty was ranked the least important. On the other hand, the most important factors for choosing a career were variety of non-clinical duties, access to child care facilities and research opportunities. Conclusion The results of this study show the top preferred specialties and career choices which can be a baseline for establishing national policies and for the improvement of graduate programs. There seems to be a need to promote mentoring activities and provide guidance and encouragement to pre-doctoral dental students in selecting the most appropriate specialty within their capability domain.

Abstract
Background There is a lack of adequate information on dentists’ knowledge about tooth avulsion and its management in Saudi Arabia. The aim of this study was to evaluate the level of knowledge about permanent tooth avulsion and its management among dentists working in Riyadh, Saudi Arabia. Methods A total of 550 dentists were contacted to request their participation in this 19-item questionnaire survey over a three-month period starting in January 2015 using convenience sampling methodology. A questionnaire consisting of demographic items and multiple-choice questions regarding knowledge of avulsion and its management was used. The level of knowledge was assessed using a scoring system that assigned one point for each correct answer and zero points for wrong answers, with a maximum possible score of ten points. An independent t-test was used to compare the level of knowledge (mean score) based on particular variables, such as sex, nationality, type of practice, current employment, working hours and whether the respondents had attended a continuing dental education (CDE) programme on avulsion management. The level of significance was set at P< 0.05. Results A total of 470 completed questionnaires were collected with data suitable for statistical analysis. The majority of the respondents were Saudi (n = 331; 72.1 %) and general practitioners (n = 278; 59.3 %). Most of the participants correctly responded to the knowledge-based questions, except the questions regarding the best storage medium (milk: 24.1 %) and the duration of follow-up by clinical and radiographic examination (5 years: 15.6 %). The mean knowledge score was 5.94 ± 1.57. Gender (P = 0.001), current employment (P = 0.045) and working hours per day (P = 0.020) had a significant effect on the mean knowledge score. Conclusions The surveyed dentists were found to have a moderate knowledge of avulsion and its management, although a relative lack of knowledge was observed regarding the duration of follow-up after replantation.

Abstract
This study compared the surface topography, hydrophilicity, and bioactivity of titanium implants after 3 different surface treatments (sandblasting and acid etching, modified sandblasting and acid etching, and thermal oxidation) with those of machined implants. One hundred indigenously manufactured threaded titanium implants were subjected to 3 methods of surface treatment. The surface roughness of the nontreated (Group A) and treated samples (Groups B through D) was evaluated with a scanning electron microscope (SEM) and profilometer. The wettability was visually examined using a colored dye solution. The calcium ions attached to the implant surface after immersing in simulated body fluid (SBF) were assessed on days 1, 2, and 7 with an atomic electron spectroscope. The data were analyzed statistically. The SBF test allowed the precipitation of a calcium phosphate layer on all surface-treated samples, as evidenced in the SEM analysis. A significantly higher amount of calcium ions and increased wettability were achieved in the thermally oxidized samples. The mean roughness was significantly lower in Group A (0.85 ± 0.07) compared to Group B (1.35 ± 0.17), Group C (1.40 ± 0.14), and Group D (1.36 ± 0.18). The observations from this in vitro study indicated that surface treatment of titanium improved the bioactivity. Moreover, results identified the implants that were sandblasted, acid etched, and then oxidized attracted more calcium ions.

Abstract
OBJECTIVE To evaluate the efficacy of Salvadora persica hexane and ethanol extracts in preserving the viability of human foreskin fibroblasts. MATERIALS AND METHODS Normal human foreskin cells were cultivated in Dulbecco modified Minimum Essential Medium (D-MEM) supplemented with 10% fetal bovine serum and 2 mM of l-glutamine. Cell pellets were suspended in the following test solutions: (1) Hank's Balanced Salt Solution (HBSS); (2) homogenized milk; (3) hexane extract of S. persica; or (4) ethanol extract of S. persica. D-MEM with no serum was used as a positive control. For each condition, cell count was adjusted to 8 × 10(5) cells/ml, and the cells were incubated in the solutions for either 30, 60, or 120 min. Subsequently, the nonviable cells were separated from the viable cells using the trypan blue dye stain. The ratio of viable to nonviable cells was recorded using a cell counter. Statistical analysis of the data was accomplished by one-way analysis of variance using SPSS Version 16. The level of significance was 5% (p < .05). RESULTS We did not detect a significant difference when comparing the percentage of viable cells in test solutions at the three incubation periods (30 min, p = 0.478; 60 min, p = 0.606; 120 min, p = 0.091). Homogenized milk preserved the viability of foreskin fibroblasts better than all other tested solutions. Incubation of cells in S. persica hexane and ethanol extracts resulted in a similar percentage of viable cells to incubation of cells in HBSS for each incubation period. CONCLUSIONS S. persica hexane and ethanol extracts should be considered an alternative storage medium to HBSS.

BACKGROUND Studies evaluating dental assistants' knowledge about tooth avulsion and its management are rare. The purpose of this study was to evaluate the level of knowledge about tooth avulsion and its management among dental assistants in Riyadh, Saudi Arabia and to assess its relationship with their educational background. METHODS A convenience sampling methodology was employed for sample selection. Over a period of four months starting in February, 2013, 691 pretested 17-item questionnaires were distributed. A total of 498 questionnaires were returned for an overall response rate of 72.1%. Six questions were related to knowledge about permanent tooth avulsion and one question was related to knowledge about primary tooth avulsion. Correct answers to these questions were assigned one point each, and based on this scoring system, an overall knowledge score was calculated. An analysis of covariance was used to test the association between the level of knowledge (total score) and the educational qualifications of the respondents (dental degree and others). A P-value of 0.05 was considered the threshold for statistical significance. RESULTS The majority of the respondents (n = 387; 77.7%) were non-Saudis (377 were from the Philippines), and 79.1% (n = 306) of the Filipinos had a dental degree. The question about recommendations for an avulsed tooth that is dirty elicited the highest number of correct responses (n = 444; 89.2%), whereas the question about the best storage media elicited the lowest number of correct responses (n = 192; 38.6%). The overall mean score for knowledge about tooth avulsion was 6.27 ± 1.74. The mean knowledge score among the respondents with a dental degree was 6.63 ± 1.37, whereas that among the respondents with other qualifications was 5.71 ± 2.08. CONCLUSIONS The educational qualifications of the surveyed dental assistants were strongly correlated with the level of knowledge about tooth avulsion and its management.

Abstract
OBJECTIVES The purpose of this study was to evaluate the in vitro sealing ability of three repair materials. Mineral trioxide aggregate (MTA; Group A), calcium phosphate cement (CPC; Group B), and light cured glass ionomer cement (GIC; Group C) when used to repair the perforation created in the pulpal floor of fifty extracted human permanent molars. MATERIALS AND METHODS Preparation of access openings and furcation perforations were done, and the teeth divided into five experimental groups (A, B, C) including two controls (D, E) with ten samples in each group randomly. Following the repair procedure, the pulp chambers and access openings were filled with composite resin and immersed in 2% methylene blue solution for 48 hours. The teeth were sectioned longitudinally and the linear dye penetration measured under a stereomicroscope. RESULTS The comparison of the linear length of micro-leakage (mm) among the experimental groups revealed no significant difference (p = 0.332). On calculating the percentage of depth of leakage to the total length of the perforation, it was observed that the mean leakage was 35.5% in Group A, 53.6% in Group B and the highest, 87.5% in Group C. The mean of leakage percentage was statistically significant by Kruskal-Wallis test (p = 0.003). The results indicated that the dye penetration used as furcation perforation repair material was least with mineral trioxide aggregate. Comparing the depth of penetration of dye, 50% of the Group A samples showed less than 25% of depth penetration. While 40% of Group B cases had more than 50% dye penetration. In our study, all Group C teeth had > or = 50% dye penetration. CONCLUSIONS The present study indicated that GIC had the greatest dye penetration followed by CPC and MTA. Mineral trioxide aggregate and calcium phosphate cement had comparatively better sealing ability than glass ionomer cement.

Abstract
Switching between linearly polarized states of slightly different optical frequencies with the same transversemode pattern is found, as the injection current is increased. Switchings found here for semiconductor rateequation models incorporating a vector electric field, birefringence, and the alpha factor are similar to previously reported experimental results.
