Abstract There is a varying degree of hand torque abilities using finger drivers among clinicians. Calibrating one's own abilities requires complicated instruments not readily available. This study evaluated a simple-to-use method that allows dental practitioners to have a quantifiable clinical assessment of relative torque ability using finger drivers to torque down dental implant components. A typodont that includes dental implants was mounted in a mannequin placed in a patient-reclined position. The subjects were asked to torque as tightly as they could a new healing abutment to an implant secured firmly in resin within the typodont. All participants wore moistened gloves when using a finger driver. The healing abutment was countertorqued using a certified precalibrated precision torque measurement device. The reading on the torque driver was recorded when the healing abutment disengaged. An average of torque values of dentists and dental students was calculated. Fifty subjects had an average maximum torque ability of 24 Ncm (male dentists: 28 Ncm; students: 22 Ncm; male students: 24 Ncm; female students: 19 Ncm). Maximum torque values for all participants ranged from 11 Ncm to 38 Ncm. There was no significant difference between groups. This study showed a varying degree of hand torquing abilities using a finger driver. Clinicians should regularly calibrate their ability to torque implant components to more predictably perform implant dentistry. Dental implant manufacturers should more precisely instruct clinicians as to maximum torque, as opposed to “finger tighten only.”

This study aimed to assess the ability of dental students and recent graduates to detect and recognize mucosal changes that are suggestive of oral cancer and potentially malignant disorders. In this cross-sectional study, a questionnaire was administered to dental students and recent graduates of Ajman University (n = 132). Completed questionnaires were received from 84 (63.6%) females and 48 (36.4%) males which included fifth-year students (n = 80), interns (n = 39), and dental practitioners (n = 13). This questionnaire was designed to assess the respondent’s ability to detect and recognize different types of oral lesions, as well as their knowledge of oral cancer appearance and malignancy potential. The overall accuracy of diagnosis was 46%. The participants correctly identified normal variations, benign tumors, malignant tumors, and premalignant lesions at rates of 60.3%, 31.0%, 55.7%, and 33.4%, respectively. There was no significant difference between the two genders in their ability to recognize and detect correct answers (females, 48.3%; males, 47.2%). According to education level, interns provided the highest percentage of correct answers (52.5%), followed by newly dental practitioners (51.9%) and fifth-year students (44.1%). Conclusion: The respondents of this survey did not exhibit a satisfactory diagnostic capability in recognizing mucosal changes consistent with the clinical presentation of oral cancer. Thus, a need exists for improved and updated educational methods for undergraduate students regarding oral cancer and potentially malignant disorders. Meanwhile, practitioners should look for oral abnormalities to provide better diagnosis and management. Practitioners should also stay up to date on the oral malignancy topic by attending workshops and clinicopathological conferences.

Explosive Force

Background. Acupuncture is often used to treat chronic conditions, such as pain. In recent years, given the importance of the explosive forces generated by shoulder muscles for the completion of motor tasks, studies in which nerves were stimulated through acupuncture to increase the explosive forces were conducted. This study explored the effect of acupuncture on explosive force production by the muscles of the female shoulder joint. Methods. Eighteen healthy women underwent shoulder adduction (Add), abduction (Abd), flexion (Flex), and extension (Ext) tests with an isokinetic measurement system. Acupuncture was used to stimulate the Zhongfu (LU1), Tianfu (LI3), Xiabai (LU4), Binao (LI14), Naohui (SJ13), Jianliao (SJ14), and Xiaoluo (SJ12) points, and electromyography (EMG) signals were recorded before and after acupuncture. Results. After acupuncture, there was a significant difference in the average maximum work, the average maximum power, the average maximum speed, the total work in Add/Abd and Flex/Ext, the EMG signals, and the stiffness of the muscles in Abd and Ext ( P < 0.05 ). There were no significant differences in the average maximum torque in Abd or Flex. Conclusion. Based on the results, there may be a significant correlation between the manipulation of different acupoints by acupuncture and the average maximum torque and stiffness. Acupuncture may stimulate nerves to activate muscles and induce a postactivation potentiation effect that improves explosive force production. Therefore, acupuncture as an auxiliary tool may increase the explosive forces generated by acupoint-related muscles by stimulating nerves.

Aim The aim of this study was to evaluate the self-perceived educational needs of a randomly selected group of general dental practitioners (GDPs) in the Merseyside region (UK). Materials and Methods Eighty-seven GDPs were randomly selected from 850 in the region and asked to complete a self-evaluation questionnaire regarding their self-perceived educational needs. Results Seventy-five (86%) responded, of which 52 (69.3%) were male and 23 (30.7%) female. There was no significant difference in self-perceived knowledge in any of the dental disciplines when gender and period of time since qualification were used as predictor variables. The majority of the GDPs felt they had a good knowledge of restorative dentistry and dental radiography. Some of the GDPs felt they had poor knowledge in implant dentistry, oral medicine, orthodontics, dental sedation techniques, oral surgery, endodontics, periodontics and dental radiography. None of the respondents felt they had poor knowledge in restorative dentistry, prosthodontics and paediatric dentistry. Seventy-four (98.7%) of the responding GDPs were motivated to attend continuing professional development (CPD) courses because of an interest in a particular dental discipline and only one reported attending out of personal learning needs. Implant dentistry was indicated by 30 (40.0%) of the respondents as their training programme of choice. Conclusions The respondents had high self-perceived knowledge of restorative dentistry, dental radiography, periodontics, endodontics, paediatric dentistry and prosthodontics. The respondents had low self-perceived knowledge of implant dentistry, orthodontics, oral medicine and dental sedation techniques. Of GDPs surveyed, 98.7% applied for courses they liked to attend, rather than needed to attend. Fifty-two per cent of male GDPs surveyed expressed a desire for training in implant dentistry.

Abstract. With the mechanization of agricultural operations, agricultural machinery management has become an extensive research field. Sizing tractors and implements to provide the most efficient power transfer has become an ongoing process with advances in technology. Utilization of the rotational power transferred through gear trains from the tractor engine to the power take-off (PTO) shaft is one of the most efficient methods of power transfer to an implement. This research used commercially available torque sensors that were installed on a tractor PTO shaft for measuring the torque delivered to an implement. The torque sensor was calibrated using the Nebraska Tractor Test Lab’s (NTTL) dynamometer by following the Organisation for Economic Co-operation and Development (OECD) Code 2 test procedure for varying PTO loads. The calibration of the sensor was verified using the full load at varying speeds test as described in the OECD Code 2. Tractor PTO shaft torque values measured by the torque sensor were compared to the NTTL’s dynamometer torque measurement. Differences in torque values measured between the sensor and the dynamometer ranged from 3 to 23 N·m. Student’s t-test showed no significant difference between the measurements during the full load varying speed tests which demonstrated that the sensor can be mounted on the tractor’s PTO shaft for torque data collection in field operations.

<p><strong><em>Objectives:</em></strong> The aim of the study was to assess the knowledge, attitude and practice related to gender and study level toward infection control among senior dental students. <strong><em>Materials and Methods:</em></strong> The self-administered questionnaire was distributed among the pre-doctoral dental students (4th and 5th levels) in the Dental Teaching Hospital at Thamar University. It included questions related to vaccinations as well as knowledge and practice toward infection control. The collected data was analyzed using Chi-squared test with significant level <em>P</em>-value &lt; 0.05. <strong><em>Results:</em></strong> Response rate was 63%. Distribution of gender among the participants was almost equal with slight increase in number of male subjects. Participated students from 4<sup>th</sup>-year level were also close to the number of students from 5<sup>th</sup>-year level. Hepatitis immunization was completed by only 12.9% male students and 17.3% females with no significant difference. Likewise, no significant difference was found among the participants by study level. More than 90% of participants reported always wearing gloves during dental treatment. Unexpectedly, however, using of other protective barriers was low. More than 90% of students, with no significant difference between genders or study levels, reported sterilizing instruments after each dental procedure. <strong><em>Conclusion:</em></strong> The present study showed that the level of knowledge and practice of infection control measures was poor among dental students. The attitude towards infectious control measures was positive, but a greater compliance was needed. Rigorous infection control training for students prior to graduation is also highly recommended.</p><p><strong>Keywords:</strong> Infection control, Compliance, Dental students, Yemen.</p>

AbstractIntroduction: The total convergence of the axial walls is the angle made between the opposing axial walls of an abutment. The lower the taper value, the better the retention of the crowns is. Obtaining a proper convergence of the axial wall is a challenge for dental practitioners due to limited access and low visibility, but it also greatly depends on the clinician’s practical skills.This study aims to compare the total convergence of axial walls obtained after tooth preparation done by different experience practitioners in various positions of the patient and different working time (different days of the week, various parts of the day).Materials and methods: To perform this study, 40 acrylate model teeth have been prepared by two last year dental students and two prosthetists. All of them performed two teeth preparations per day in every working day of a week. All the prepared teeth have been photographed, and digitally measured.Results: The extremely statistically significant difference was found in the two beginners’ case, the values of the second beginner being much higher, as in the two experienced operators, where the values are higher for the second prosthetist.Conclusion: The total convergence of the axial wall did not depend on the operators’ experience or education level.

Abstract Background This study evaluated the operating performance of an implant navigation system used by dental students and dentists of prosthodontic background with varying levels of experience. A surgical navigation system and optical tracking system were used, and dentists’ accuracies were evaluated in terms of differences between the positions of actually drilled holes and those of the holes planned using software before surgeries. Methods The study participants were 5 dental students or dentists who had studied in the same university and hospital but had different experience levels regarding implants. All participants were trained in operating the AqNavi system in the beginning of the study. Subsequently, using 5 pairs of dental models, each participant drilled 5 implant holes at 6 partially edentulous positions (11, 17, 26, 31, 36, and 47). In total, each participant conducted 30 drilling tests. Results In total, 150 tests among 5 dentists at 6 tooth positions (11, 17, 26, 31, 36, and 47) were conducted. Although a comparison of the tests revealed significant differences in the longitudinal error (P < .0001) and angular error (P = .0011), no significant difference was observed in the total error among the dentists. Conclusions A relatively long operating time was associated with relatively little implant experience. Through the dental navigation system, dental students can be introduced to dental implant surgery earlier than what was possible in the past. The results demonstrated that the operational accuracy of the dental implant navigation system is not restricted by participants’ implant experience levels. The implant navigation system assists the dentist in the ability to accurately insert the dental implant into the correct position without being affected by his/her own experience of implant surgery.

Abstract Background: Australia possesses a highly multicultural demographic, and thus dental practitioners are likely to encounter culturally and linguistically diverse individuals regularly. It is important for dental practitioners to be culturally competent, however, cultural competency education is highly variable in the curricula of dentistry and oral health courses in Australia, and research is largely limited to dentistry students. This study aims to investigate and compare perceived attitudes, beliefs and practices of cultural competence amongst first and final year Doctor of Dental Surgery (DDS) and Bachelor of Oral Health (BOH) students at the University of Melbourne Dental School.Methods: Following ethics approval, anonymous questionnaires were completed by 213 participants. The questionnaire was adapted from Schwarz’s Healthcare Provider Cultural Competence Instrument (HPCCI) and consisted of five scales. Data was analysed using SPSS V 24.0 software.Results: A total of 213 students participated in this study (response rate = 88%) The majority of participants were female (n=114, 53.5%) and the mean age of 23.5 years (range 18 - 40). The majority of participants were Australian born (n=110) with 74.6 percent (n=159) first generation Australians. Participants who identified as Australian represented 35.7 percent (n=76) with 66.1 percent (n=141) identified as partly Australian. Multivariate analysis indicated that, after controlling for other independent variables in the model, those who had the highest cultural competence score were female, who self-identify as “Australian”, who were in the final year. Furthermore, those who were in the final BOH year scored significatively higher than final year DDS students.Conclusion: The findings of this study suggest that there is a significant difference in students self-reported cultural competence at different stages of their education. This may be attributed to differences in cultural competence education, scope of practice and the type of patient encounters that students may experience. Future research should involve follow up to create longitudinal data, as well as research at other dental schools in Australia and overseas.
