A Simplified Prosthetic Implant Loading Protocol: 1-Year Clinical Follow-Up Study
Purpose. To retrospectively investigate the one-year clinical outcome following a standardized treatment protocol for immediate loading. The protocol mandates predefined requirements for implant stability. If fulfilled, immediate loading of the implants is performed with a simplified prosthetic protocol which includes one-time impression at the time of surgery and definitive restoration within eight weeks. Methods. Twenty-five patients were treated with 48 Neoss ProActive Tapered implants. Minimum primary stability was established before subjecting the implants to immediate nonfunctional load. Definitive prostheses were delivered six to eight weeks from implant placement. Insertion torque (IT), resonance frequency analysis (RFA), intraoral radiographs, and impressions of implant positions were registered at implant placement. During clinical follow-up, RFA was measured at two, four, and six to eight weeks and six months from implant placement to monitor continued implant stability. Marginal bone level measurements were performed at implant placement, six-month, and one-year follow-up visits. Results. IT was over 40 N·cm for 46 implants. Two implants with IT <30 N·cm were both splinted to another implant with IT >50 N·cm, tightening the retention screw with low forces. No implants were lost during the observation period. Mean RFA measurements remained stable without any decrease during the initial six-month healing phase. Mean marginal bone remodeling was −0.47 ± 0.38 mm from implant placement to 1 year. No significant difference was found for marginal bone remodeling between implants placed in the healed bone or fresh extraction sockets. Conclusion. Within the limits of this study, it is concluded that using a simplified immediate loading protocol can be predictably applied to reduce the overall treatment time and the number of clinical sessions.
Acceptance of Leadership Empowerment Efforts for Female Employees in Three Dental Hospitals
Introduction. Empowerment is an organisational effort in increasing the willingness and ability of employees to be more independent in performing their duties. Employee leadership empowerment substantially increases motivation, performance, and commitment to the organisation. Leadership empowerment includes self-determination, competence, meaning, and impact. The purpose of this study was to determine the acceptance of leadership empowerment efforts for female employees in three dental hospitals in Bandung. Methods. A descriptive survey was conducted and the study population was dental hospitals in Bandung. The exclusion criteria were dental hospitals which unwillingly followed the research. The inclusion criteria were dental hospitals that have empowered female employees. The data collection technique was performed with total sampling. The research sample amounted to 102 people from three dental hospitals—all data were collected using a validated questionnaire. Data analysis was performed using relative frequency distribution. Results. Leadership empowerment for female employees in three dental hospitals in Bandung has been given by each. The highest acceptance of empowerment efforts for female employees was shown by employees of Dental Hospital of Jenderal Achmad Yani University, followed by Dental Hospital of Universitas Padjadjaran, and subsequently Dental Hospital of Maranatha Christian University. The level of acceptance of empowerment efforts that need to be improved in three Dental Hospitals in Bandung was self-determination or autonomy at work. Employees must be given more freedom on performing their duties, developing their careers, and acting more independently. Conclusion. Acceptance of leadership empowerment for female employees in three dental hospitals in Bandung has been demonstrated in each. Acceptance of leadership empowerment efforts in all subdimensions of empowerment needs to be improved, primarily related to self-determination.
Dental Service Utilization and Barriers to Dental Care for Individuals with Autism Spectrum Disorder in Jordan: A Case-Control Study
Individuals with disabilities are at higher risk for oral diseases such as caries and periodontal disease. Therefore, regular dental care is essential to maintain oral health. However, individuals with disabilities encounter difficulties in accessing dental care. The challenges and barriers to oral care faced by individuals with autism spectrum disorder (ASD) have not been addressed in Jordan. The aim of this study was to examine the use of dental services in individuals with ASD in Jordan and identify barriers that affect their access to dental care in comparison with individuals without ASD. A case-control study was carried out among 296 parents/caregivers of individuals with ASD and individuals without ASD, which involved completion of a self-designed questionnaire. The majority of the participants in both groups had visited the dentist in the year preceding completion of the questionnaire. The main reason for visiting dental services was toothache (43%), and the least common reason was routine checkup (11.6%), with a significant difference () observed between the two groups. Barriers including embarrassment (43.5%), a lack of specialized dental staff (28.6%), a lack of knowledge of how to treat people with disabilities (26.6%), and inadequate facilities (34%) were significantly () more likely to be reported by individuals with ASD than the controls. In conclusion, knowing and understanding the barriers to accessing dental care could improve overall health for individuals with ASD. Furthermore, recognizing the challenges in accessing dental care for this population could help oral health professionals to minimize these difficulties.
Effect of Marginal Designs on Fracture Strength of High Translucency Monolithic Zirconia Crowns
Introduction. Monolithic zirconia is able to achieve certain aesthetic, but its durability in resisting fracture has been questioned, as fractures often originate from margins of restoration. This study determined fracture resistance of highly translucent monolithic zirconia crowns with different margin designs in terms of marginal thickness and collar height. Materials and Methods. Zirconia blanks (Ceramill® Zolid HT+) were selected for the fabrication of zirconia crowns according to different designs, including varying margin thicknesses (light chamfer, CL; heavy chamfer, CH) and collar heights (no collar, NC; low collar, LC; high collar, HC), which resulted in CLNC, CLLC, CLHC, CHNC, CHLC, and CHHC groups (15 crowns each). The crowns were seated on a metal die and loaded vertically through round end punch (θ = 10 mm), contacting with inclined planes of cusp in a testing machine with crosshead speed of 0.2 mm/min until fracture. Videos with a rate of 50 frames/second were used to record fracture. Fracture load (N) and durable period (s) were compared for significant differences using ANOVA and Bonferroni test (α = 0.05). Results. The mean ± sd of fracture load (N) and durable time (s) were 3211 ± 778 and 212 ± 47 for CLNC; 3041 ± 1370 and 188 ± 53 for CLLC; 2913 ± 828 and 192 ± 27 for CLHC; 4226 ± 905 and 245 ± 35 for CHNC; 4486 ± 807 and 228 ± 29 for CHLC; and 4376 ± 1043 and 227 ± 37 for CHHC. This indicated that marginal thickness had a significant influence on load-bearing capacity and durable time (). No significant impact of collar height was shown, either on load-bearing capacity or durable time (). No interaction between two factors was presented (). Conclusions. Heavy chamfer margin provided stronger zirconia crown than light chamfer, but both were capable of withstanding fracture load higher than maximum masticatory force. Neither presence nor absence of collar indicated any impact on strength. Fabrication of zirconia crowns with either heavy or light chamfer margin and either presence or absence of collar, with the consideration of emergence profile, should be considered.
Creation and Evaluation of an Endodontic Diagnosis Training Software
Objective. The purpose of the study is to evaluate a user-friendly, comprehensive, fully integrated web- and mobile-based application that was specifically developed to guide learners and help them practice and train in pulpal and periapical diagnosis. Methods. The software was designed for assistance in the diagnosis of the pulpal and the periapical area. The software contained questions and tests, e.g., presence or absence of signs and symptoms, cold test, percussion, palpation, and radiographic examination that the user must answer to arrive at the final diagnosis. An electronic survey was prepared to evaluate the effectiveness, productivity, and accurateness of the software. The software and the electronic evaluation survey were sent by e-mail to dental students, endodontist, general dentists, and dental interns who study or work in four Saudi dental colleges. Data was analyzed using descriptive statistics. Result. A total of 203 questionnaires were completed. Results showed that 29% of the participants were highly satisfied with the software; 40% gave a very good rating about the application satisfaction, while only 2% reported a poor degree of satisfaction with the software. Results also showed that students accurately selected the correct diagnosis but received relatively low diagnostic proficiency scores because they did not request diagnostic data in a pattern similar to experts. Conclusion. In conclusion, the software is promising as an effective and efficient tool for teaching and assessing the diagnostic skills of learners.
Practices and Attitudes of Dental Loupes and Their Relationship to Musculoskeletal Disorders among Dental Practitioners
Objective. A dental loupe is a tool used by many dentists and dental students to improve visual field and performance. This study aims to assess the practices and attitudes about dental magnification loupes and their relationship to musculoskeletal disorders. Materials and Methods. A cross-sectional study was conducted involving 400 dental students and dentists in four dental colleges in Jeddah, Saudi Arabia. The mean age was 28.35 years (SD = 8.50), and 56% of the participants were male. Also, 70.75% were students or interns, while 29.25% were dentists. Data gathering was conducted using a questionnaire that was composed of four sections: demographic, magnification devices usage, attitude toward dental loupes, and the Nordic questionnaire to assess musculoskeletal disorders. Results. A total of 66% of participants had used dental magnification tools before, but only 12.25% were using dental loupes at the time of the study. The main reported advantages of dental loupes were comfort in vision (59.25%) and improved work accuracy (53%), while the main disadvantage was difficulty in visual measurement (28.5%). A total of 73.25% reported that price was the main barrier to the use of dental loupes. Lower back (63.5%), neck (65.25%), and shoulder (46.25%) pain were the most frequently reported areas of discomfort. There was a significant relationship (<0.05) between the use of dental loupes and lowered levels of reported discomfort in the lower back, neck, shoulders, elbows, upper back, and feet. Conclusion. There are few dental professionals who use dental loupes in Saudi Arabia. There was a significant relationship between dental loupes use and reduction of musculoskeletal disorders among dental students and dentists.
