We aimed to evaluate the impact of Virtual Reality Dental Simulators (VRDS) on preclinical training in endodontics for undergraduate dental students. Purposive sampling technique was used to target undergraduate dental students at two dental schools: in Qatar and Turkey. After training on endodontic access cavity preparation on upper anterior teeth using acrylic teeth on dental mannequins and virtual reality haptic dental simulator, a questionnaire based on a combination of open- and closed-ended items was distributed to the participants. The sample included 60 dental undergraduate students. The participants reported positive experiences with VRDS and 76% considered it to be helpful in improving their fine motor skills. Endodontic access cavity preparation on VRDS was perceived to be similar to natural and acrylic teeth by 73.34% and 53% of participants, respectively. Overall, 85% of participants supported the use of VRDS training to supplement conventional training on dental mannequins but also recommended the need for improvements in VRDS training in endodontics. The findings of this study underscore the benefits of VRDS in endodontics. Future research involving larger samples from multiple institutions may help to optimize VRDS in undergraduate dental education.

The transition of an undergraduate dental student to an actual practicing dentist is a crucial phase and ensuring the preparedness of graduates for the complexity and demands of contemporary dental practice is a challenging task. This study aimed to evaluate the self-perceived preparedness of undergraduate dental students and house officers in the dental colleges of Pakistan. A cross-sectional national study was planned to collect information from dental students and new graduates in Pakistan. The pre-validated Dental Undergraduates Preparedness Assessment Scale (DU-PAS) was used. A purposive sampling technique was utilized to recruit house officers and undergraduate dental students from 27 dental schools in Pakistan. The data analysis was carried out using the R statistical environment for Windows (R Core Team, 2015). A total of 862 responses with 642 females and 219 males were analyzed in the study. Overall, the clinical skills score was 30.56 ± 9.08 and the score for soft skills was 30.54 ± 10.6. The mean age of the participants was 23.42 ± 1.28. Deficiencies were reported in various soft skills and clinical skills attributes. The results highlighted the strengths and weaknesses of dental students and new graduates in Pakistani dental institutions. The findings may be used to further develop and strengthen the teaching and training of dental students in Pakistan.

Endodontic technical errors are the foremost cause of treatment failure. A thorough understanding of root canal configuration (RCC) is essential to prevent these iatrogenic errors. This study used CBCT images to determine the association between root canal configuration, endodontic technical errors, and periapical status. CBCT images of 101 patients, including total of 212 obturated premolars (256 canals) were assessed. RCCs were classified according to the Vertucci system. The presence of endodontic errors and periapical lesions associated with each RCC was noted. Presence or absence of coronal restoration and its association with periapical radiolucency was recorded. The most frequent RCC was Type I (199 cases; 77.73%), followed by Type II (26 cases; 10.15%), Type IV (22 cases; 8.59%), Type V (4 cases; 1.56%), Type III (4 cases; 1.56%), and Type VI (1 case; 0.39%). Under-filling and non-homogeneous filling were the most common technical errors. Prevalence of periapical radiolucency was 81% in the presence of technical errors. The absence of coronal restoration caused apical lesions in 93% of cases. The frequency of endodontic technical errors increased as the root canal configurations became more complex. Periapical lesions occurred more often in teeth with endodontic errors and/or absent coronal restoration.

Purpose: This study evaluates the influence of patient factors and clinical outcomes in full-mouth rehabilitations using dental implants under general anesthesia. Key parameters include patient demographics, medical histories, procedural details, and postoperative outcomes. Methods: A retrospective analysis was conducted on patients undergoing full-mouth rehabilitation with dental implants under general anesthesia from 2020 to 2023. Patient records were reviewed to assess age, gender, systemic conditions, surgical complications, and treatment outcomes. Data analysis was performed to identify significant associations between patient factors and clinical outcomes. Results: Among 120 patients, the mean age was 58.6 ± 12.4 years, with 65% male and 35% female patients. Comorbidities such as diabetes (25%) and cardiovascular disease (20%) were prevalent. A 96% implant survival rate was achieved after one year. Postoperative complications included minor infections (5%) and transient neuropathy (2%). Patients with controlled comorbidities demonstrated better outcomes compared to those with uncontrolled conditions (P < 0.05). Conclusion: Patient factors such as age and controlled systemic conditions significantly influence clinical outcomes in full-mouth rehabilitations under general anesthesia. The procedure is safe and effective when appropriate preoperative planning and patient selection are undertaken.

Aim: To compare the effectiveness of conventional and rotary NiTi files for Gutta-Percha (GP) removal in straight roots during retreatment root canal treatment (RCT), using manual Hedstrom files and ProTaper Universal System, respectively. Methods: It was an in-vitro experimental study using non-probability consecutive sampling. Sixty extracted single rooted maxillary and mandibular permanent teeth with straight canals were selected for this study. Following preparation, the root canals were filled with GP along with a sealer and kept for two weeks in a moist environment at room temperature. Thirty teeth were randomly allocated to the study and control groups each. GP removal was accomplished with Hedstrom files and Pro Taper retreatment files in group 1 and group 2, respectively. Digital radiographs were obtained using Kodak RVG digital radiography system software version VER.6.10.8.3-A and analyzed for the difference of opacities indicating residual GP. AutoCAD 2006 software was used to outline the root canal and the residual root filling. Independent sample t test was used to compare the total residual GP in both groups. Results: No significant difference in the residual root filling was observed following removal with conventional Hedstrom files versus ProTaper universal retreatment files. In both groups, the residual GP was confined to the apical third of the roots. Conclusion: ProTaper Universal Retreatment files and manual Hedstrom files are equally effective in the removal of GP in straight canals.
