DATA: Studies assessing OHRQoL amongst patients aged ≥18 years, before and after rehabilitation with RPDs of any type and design, were included. The quality of included studies was evaluated using the Cochrane risk of bias tools. Meta-analysis was conducted using a random-effect model.
SOURCES: MEDLINE, EMBASE and CENTRAL, up to March 29, 2022.
STUDY SELECTION AND RESULTS: Thirteen studies were eligible and eight were included in the meta-analysis. The studies had moderate to serious risk of bias. There was a very low level of certainty that OHRQoL, as measured using OHIP-14, improved 3 months after RPDs were fitted (222 participants, MD: -12.0, 95% CI: -16.1, -7.9, p<0.001) and after 6 months (101 participants, MD: -10.5, 95% CI: -16.4, -4.6, p<0.001). At 12 months post-treatment, RPD rehabilitation did not result in statistically significant improvement in OHIP-14 scores (62 participants, MD: -12.7, 95% CI: -26.1, 0.6, p = 0.06). However, the assessment using OHIP-49 at 12 months showed significant improvement (87 participants, MD: -34.8, 95% CI: -41.9, -27.7, p<0.001), with low certainty of evidence.
CONCLUSIONS: Based on the limited evidence available, this review found that RPD rehabilitation appear to improve OHRQoL in the short term up to 6 months, with a very low level of certainty. The long-term effect of RPD treatment on OHRQoL after 12 months is inconclusive. There is currently insufficient evidence on the effect of RPD treatment on OHRQoL. This review highlights the need for more and better quality studies.
CLINICAL SIGNIFICANCE: Data on RPD outcomes are summarised, aiding clinicians in providing evidence-based patient-centred care that matches patients' needs and expectations. Recommendations for future research were also highlighted.

METHODS: Fifty-four dental students enrolled in 2018 were recruited as participants and assigned to two groups. Both groups were given the same lecture and asked to watch the same video in either the enhanced or non-enhanced version. The enhanced video was modified with the contemporaneous subtitle of the presenters' dialogue, text bullet points and summary text pages. The knowledge acquisition from the two types of video was subjected to pre- and post-tests one month after the students watched the video. A questionnaire was used to evaluate the students' perceptions of the learning experience and a performance test on practical skills was performed after six weeks. All the students responded to the test (100%).
RESULTS: The enhanced video demonstration improved the students' short-term knowledge acquisition after they watched the video, with an average score of 1.59 points higher in the enhanced group than in the non-enhanced group (p
MATERIAL AND METHODS: Twenty-eight participants treated with cantilevered RBFDP at an increased OVD were prospectively recruited. They were asked to answer a validated patient satisfaction questionnaire based on six parameters during the 12-week review visit.
RESULTS: 71.4% of the participants were completely satisfied with the color, shape, and function. Twenty-one (75%) participants reported no complaints about the prostheses. 89.3% will recommend this treatment option to others. There was a significant difference between males and females in avoiding loading on the prostheses (p = 0.015). The level of satisfaction did not differ by age, ethnicity, location, and arch of the prostheses (p > 0.05).
CONCLUSIONS: Patient satisfaction toward RBFDP cemented by using the Dahl approach was generally high on all the parameters at the 12-week review visit.
Materials and Methods: The present systematic review was carried out according to PRISMA guidelines. The search was carried out on PubMed/MEDLINE, Cochrane collaboration, Science direct, and Scopus scientific engines using selected MeSH keywords. The articles fulfilling the predefined selection criteria based on the fit and accuracy of removable partial denture (RPD) frameworks constructed from digital workflow (CAD/CAM; rapid prototyping) and conventional techniques were included.
Results: Nine full-text articles comprising 6 in vitro and 3 in vivo studies were included in this review. The digital RPDs were fabricated in all articles by CAD/CAM selective laser sintering and selective laser melting techniques. The articles that have used CAD/CAM and rapid prototyping technique demonstrated better fit and accuracy as compared to the RPDs fabricated through conventional techniques. The least gaps between the framework and cast (41.677 ± 15.546 μm) were found in RPDs constructed through digital CAD/CAM systems.
Conclusion: A better accuracy was achieved using CAD/CAM and rapid prototyping techniques. The RPD frameworks fabricated by CAD/CAM and rapid prototyping techniques had clinically acceptable fit, superior precision, and better accuracy than conventionally fabricated RPD frameworks.
MATERIALS AND METHODS: Two reviewers independently searched two electronic databases, PubMed and Scopus. The search was complemented from references of included studies and published reviews. Studies published in the English language through January 2021 that had assessed and documented the clinical and radiographic failure of crown or FPD in vital permanent teeth due to pulpal or periapical pathology with a follow-up of at least 12 months were selected. Data screening, data collection and extraction of data was performed. Quality of studies involved was analyzed using the Newcastle-Ottawa Quality Assessment Scale for cohort studies. Meta-analysis was done using random effects model. Publication bias was assessed using funnel plots.
RESULTS: Electronic searches provided 10,075 records among which 20 studies were selected for systematic review and 7 studies were selected for meta-analysis. With respect to quality assessment, all the studies involved were considered as high quality as the score in scale ranged between 6 and 9 as per the Newcastle-Ottawa Quality Assessment Scale for cohort studies. The meta-analyses showed that there was no statistically significant difference in the incidence of the loss of pulp vitality or pulp necrosis through clinical and radiographic examination with the follow up period of 5 years: p < 0.001, 95% CI: 0.96-1.00, I2 = 77.84%; 10 years: p < 0.001, 95% CI: 0.88-0.95, I2 = 93.59%; 15 years: p < 0.001, 95% CI: 0.92-0.96, I2 = 94.83%; and 20 years: p < 0.001, 95% CI: 0.94-0.96, I2 = 95.01%.
CONCLUSIONS: The meta-analysis revealed clinical and radiographic success rate ranging between 92% to 98% at different follow up periods ranging between 5 years and 20 years. Future high-quality randomized clinical controlled trials with a larger population are required to confirm the evidence as only observational studies were considered in this paper.
