BACKGROUND The success of fixed dental prosthesis (FDPs) delivered to the patients depends upon the implementation of appropriate laboratory procedures and dental materials which are required during fabrication of that prosthesis. Inappropriate technique during its fabrication may not always hamper the esthetic end results or fit, but may also hamper the longevity as well. Thus, knowledge about the dental materials as well as the basic laboratory procedures among the dental laboratories should be regularly assessed to assure good quality work. This survey was conducted to assess the knowledge among laboratory technicians regarding the routinely used laboratory procedures and materials for fabrication of FDPs in dental laboratories in Western Maharashtra region with the help of a validated questionnaire. METHODS An electronic survey was conducted with the help of a validated questionnaire that was circulated to 49 laboratories in Western Maharashtra region. The feedback was gathered from laboratory technicians and was then statistically analysed to achieve the objectives of the study. RESULTS 48.8 % of laboratories confirmed that technicians working for them were registered under the state council. 51 % agreed that they only used dental materials that were American Dental Association (ADA) specified. The most common gypsum product for pouring of impressions was dental stone. 65.9 % of the technicians agreed that they inspected the cast before starting the fabrication procedure. Die preparation and ditching procedure was done by 52.9 % and 35.7 % laboratories respectively. Only 38.1 % agreed of using beryllium free alloy ingots; in 66.7 % laboratories, ceramic work was carried out in a separate ceramic room with 76.2 % having adequate ventilation provisions. CONCLUSIONS Response of technicians in Western Maharashtra region regarding their knowledge about basic laboratory procedures in FDP fabrication indicates several areas of weakness. Avoiding such inadequacy in laboratories can significantly reduce FDP failure rates. KEY WORDS Fixed Dental Prosthesis, Dental Laboratory, Survey

The aim of this paper is to report a clinical case with bilateral missing mandibular second premolars that were restored by metal-ceramic inlay-retained fixed dental prostheses. The first prosthesis was of a traditional design and the second was of a modified design. The suggested design is created by modifying the retainer wings of the traditional resin-bonded inlay-retained fixed dental prosthesis and covering the wings with composite resin. The modified design is relatively conservative, esthetic and provides an extra element for the retention of posterior metal-ceramic inlay-retained fixed dental prostheses.

Precision And Accuracy

The aim of this study was to compare the accuracy and precision of 3D printers used to obtain models of fixed dental prostheses. A fixed dental prosthesis preparation was scanned and reproduced by four 3D printers: RapidShape P40, Asiga MAX, Varseo, and Photon. The impressions were scanned again, and the dataset was compared to the original dataset. Mean discrepancies (µm) were 52.97±20.48 (RapidShape P40), 68.27±43.53 (Asiga MAX), 62.22±56.21 (Varseo), and 80.03±28.67 (Photon). There was no difference (p=0.314) in accuracy; however, the precision differed (p=0.015) among the 3D printers. The printers had distinct precision but did not differ in accuracy.

Exact Point

Lasers have been well integrated in clinical dentistry for the last two decades, providing clinical alternatives in the management of both soft and hard tissues with an expanding use in the field of dental materials. One of their main advantages is that they can deliver very low to very high concentrated power at an exact point on any substrate by all possible means. The aim of this review is to thoroughly analyze the use of lasers in the processing of dental materials and to enlighten the new trends in laser technology focused on dental material management. New approaches for the elaboration of dental materials that require high energy levels and delicate processing, such as metals, ceramics, and resins are provided, while time consuming laboratory procedures, such as cutting restorative materials, welding, and sintering are facilitated. In addition, surface characteristics of titanium alloys and high strength ceramics can be altered. Finally, the potential of lasers to increase the adhesion of zirconia ceramics to different substrates has been tested for all laser devices, including a new ultrafast generation of lasers.

BackgroundThe global COVID-19 pandemic has impacted on the mental health of individuals, particularly those with chronic illnesses. We aimed to quantify stress, anxiety and depression among individuals with Inflammatory bowel disease (IBD) in Australia during the pandemic.MethodsAn electronic survey was made available to IBD patients Australia-wide from 17 June to 12 July 2020. Respondents with an underlying diagnosis of IBD and over 18 years of age were included. A validated questionnaire (Depression, Anxiety, Stress Score-21, DASS21) was used to assess depression, anxiety and stress. Data on potential predictors of depression, anxiety and stress were collected.Results352 participated in the survey across Australia. 60.5% of respondents fulfilled DASS criteria for at least moderate depression, anxiety or stress. 45% reported a pre-existing diagnosis of depression and/or anxiety. Over 2/3 of these respondents reported worsening of their pre-existing depression/anxiety due to the current pandemic. Of those without a pre-existing diagnosis of anxiety or depression, high rates of at least moderate to severe depression (34.9%), anxiety (32.0%) and stress (29.7%) were noted. Younger age (OR 0.96, 95% CI 0.94 to 0.98, p<0.001), lack of access to an IBD nurse (OR 1.81, 95% CI 1.03 to 3.19, p=0.04) and lack of education on reducing infection risk (OR 1.99, 95% CI 1.13 to 3.50, p=0.017) were associated with significant stress, anxiety and/or depression.ConclusionHigh prevalence of undiagnosed depression, anxiety and stress was identified among respondents. Improved access to IBD nurse support and greater attention to education are modifiable factors that may reduce depression, anxiety and/or stress among patients with IBD during the pandemic.

Abstract Background The benefits of student acquired Problem-based learning (PBL) skills in the preclinical phase might carry-on into the clinical phase and the application of these skills in the understanding of clinical subjects remains uncertain. Current study is aimed at exploring the perceptions of carry-on benefits of problem-based learning skills into the clinical phase. Methods Using a pre-validated questionnaire, the benefits of PBL skills in the clinical phase were evaluated by seven questions on a five-point Likert scale. A non- parametric test assessed variation between the groups. p-value of <0.05 was considered statistically significant for this study. Results The overall mean score of the perception of acquired preclinical benefits of PBL in clinical phase was 4.57±2.41; females demonstrating higher mean scores (4.86±2.15) as compared to male students(4.23±2.67). Overall, fifth-year students showed a high satisfaction(4.84±2.36) of the effective use of preclinical PBL skills in clinical courses. 5th-year female student’s perception of preclinical collaborative learning skill benefits in clinical courses was significantly(p<0.03) higher than male. Conclusions The study concludes that a substantial preclinical PBL educational strategy benefits are carried into the clinical phase especially the long-lasting self-direct learning, collaborative learning and problem-solving skills consistent with demanding abilities of a competent physician.
