Patients' hospital stay was directly related to the complexity of the orthognathic procedure, the operation time, time spent in ICU and the year in which the operation was done. There was a significant reduction in the LHS over the progressing years and this could be due to an increase in experience and knowledge of the operators and an improvement in the hospital facilities.

The use of prophylactic antibiotics for the prevention of infective endocarditis following dental procedures has long been debated and there is still confusion regarding its efficacy. As a result, the prophylactic treatment varies considerably amongst different countries across the world and amongst different dental practitioners. Aim: To evaluate the knowledge of dental staff regarding the guidelines for the prevention of infective endocarditis.Methods: This was a cross sectional analytical study which included all staff members. A self administered questionnaire was used and responses were “graded” according to the American Heart Association (AHA) guidelines.Results: The response rate was 87% (N=39) and 97% reported to use the AHA guidelines; 66% reported their knowledge was based on previous training and scientific journals. Of those cardiac conditions and dental procedures which required prophylaxis; 47% and 65% chose the correct option, respectively. Penicillin was prescribed as the drug of choice by the majority of respondents. Conclusions: Although almost all staff reported the use of the AHA guidelines, many were not following them. The study emphasizes the need for continuous education and evaluation of this critical aspect of dentistry.

The development of local anesthesia in dentistry has marked the beginning of a new era in terms of pain control. Lignocaine is the most commonly used local anesthetic (LA) agent even though it has a vasodilative effect and needs to be combined with adrenaline. Centbucridine is a non-ester, non amide group LA and has not been comprehensively studied in the dental setting and the objective was to compare it to Lignocaine. This was a randomized study comparing the onset time, duration, depth and cardiovascular parameters between Centbucridine (0.5%) and Lignocaine (2%). The study was conducted in the dental outpatient department at the Government Dental College in India on patients attending for the extraction of lower molars. A total of 198 patients were included and there were no significant differences between the LAs except those who received Centbucridine reported a significantly longer duration of anesthesia compared to those who received Lignocaine. None of the patients reported any side effects. Centbucridine was well tolerated and its substantial duration of anesthesia could be attributed to its chemical compound. Centbucridine can be used for dental procedures and can confidently be used in patients who cannot tolerate Lignocaine or where adrenaline is contraindicated.

The aim of the present study was to assess visibility of the mandibular canal (MC) on cross-sectional cone beam CT (CBCT) images at impacted mandibular third molar (IMTM) sites. CBCT images for 150 IMTMs were selected for the study. The type of tooth impaction (horizontal, vertical, mesial and distal) and location of the MC (inferior in contact and superimposed) were evaluated on pseudopanoramic images. Cross-sectional images were generated and two observers evaluated the location of the MC (buccal, lingual, inter-radicular and inferior) and its visibility using 3-point scoring scale: (1À3, goodÀexcellent). KruskalÀWallis test was used to examine the differences in the visibility of the MC according to its location and the type of tooth impaction. The visibility scores of the MC were good, very good and excellent at 3, 25 and 122 IMTM sites, respectively. There were no statistically significant differences in the visibility scores of the MC according to its location or the type of tooth impaction (P < 0.05). Therefore, despite the different locations of the MC and different types of tooth impaction at IMTM sites, the visibility of the MC was excellent on most of the cross-sectional CBCT images. CBCT is considered a valuable diagnostic tool for achieving these results.

Although online teaching has been implemented worldwide, specifically in higher education, resistance to technology use exists, as faculty members may lack technology familiarity and may require both guidance and training. The present study evaluated faculty members’ satisfaction towards distance teaching as imposed during the COVID-19 pandemic. An online survey which evaluated socio-demographics and faculties ‘satisfaction toward distance education was validated and completed by 286 faculties from different faculty-fields of education across all Universities in Jordan. Factor analysis was conducted to validate the questionnaire and univariable analysis was conducted to evaluate demographic variables association with satisfaction degree. The confirmatory factor analysis indicated that the most suitable structure for the study data was a 3-factor model constructed from 21 items. The three factors were students-related factor, institution-related factor and technology-related factor. The scores for the three factors were 2.66, 2.00 and 3.33 out of 5 respectively. Faculties who received training for online teaching and those who have attended courses as a trainee were more satisfied with distance education. In conclusion, the faculties’ low satisfaction level reported in the present study shows margin for distance education improvement by conducting intensive training courses for online teaching with the aim of improving faculties’ satisfaction levels towards a web-based teaching environment and hence improving education outcomes.
